Dual-core desktop CPU bout: AMD vs. Intel part4

6: Video encoding

Results with night vision may vary.

With products such as Microsoft's Windows Media Center operating system and the video-capable iTunes 7, a computer's ability to encode video will only become more important. That said, we suggest you pay extra attention to these video-encoding scores if you're building a PC with any intent to integrate it into your home entertainment scheme.



Intel made its most competitive showing on our video-encoding test. AMD still wins the round, but the difference is not as pronounced as it is on other tests. The Athlon 64 X2 4800+ takes its familiar perch atop the performance chart, and both it and the Athlon 64 X2 4600+ stand out from the pack in a noticeable way. The processors in the middle of the performance scale, however, are so close that they're statistically tied, with less than 4 seconds and 2 percentage points between the Pentium D 840 and the Athlon 64 X2 4200+. Perhaps we should no longer be surprised that AMD's midrange chips compete well with Intel's higher-end CPUs, but that AMD's dual-core CPUs have maintained such a consistent streak of high performance should impress even the most adamant of Intel apologists.

Winner: AMD

7: Price vs. performance

Which CPU has the most juice per dollar?

Our price-vs.-performance chart shows just how much performance you're getting per dollar spent. We based our price figures on the suggested prices from each company, but that strategy has a caveat: For AMD, the X2-series chips have per-individual-unit pricing, which you can read for yourself here. Intel, on the other hand, provides only a suggested equivalent price of a chip as if it was purchased in a 1,000-unit lot. And of course both of those listings are estimates of what you'll really find in the market, so while we used the vendor-provided figures for the sake of consistency,we suggest you shop around.
Given the provided prices then, it's plain that Intel can afford to put its 80 percent market share to good advantage, at least with the low-end chips that most people are likely to purchase. At a suggested price of $241, the Pentium D 820 chip is the least expensive of the bunch. But while lower is generally better on such a scale, keep in mind the balance between the two ratings. The best bang for the buck in our minds is the $507 AMD Athlon 64 XS 4400+, which beat the $530 Intel Pentium D 840 on five of our six tests. And on the high end, the $803 AMD Athlon 64 X2 4800+ is the decisive winner, easily taking out the $999 Intel Pentium Extreme Edition 840 (which, incidentally, we couldn't find for less than $1,029).

Winner: AMD

4: Photo editing

Depending on your level on interest in the hobby, photo editing might mean anything from a simple edge crop of a shot from your daughter's wedding to running a wedding photo business of your own. Our Photoshop test represents a task common to many photographers: converting large-size images to Web-appropriate file sizes.




The results of this round mirror those of the first round with our SysMark application test. AMD has a clear advantage with the higher-end chip, and the results get closer as you move down into the mainstream and lower-end chips. AMD's top three X2 chips finished at the top, but Intel and AMD exchanged even blows when we looked at the Pentium D 840, 830, and 820 chips matched up against the Athlon X2 4200+ and 3800+ chips. The round still goes to AMD for the showing by its top three X2 chips, but at least Intel was competitive in this round--unlike the last two.
Winner: AMD

5: MP3 encoding

Now root kit free.

If there's one modern multimedia task that affects the broadest swath of people, it might be MP3 encoding. Even though loading music into iTunes from a CD isn't exactly demanding, it's a common enough task that is easy to relate to the test results. iTunes also has the distinction of being a multithreaded application, which means that it's programmed to take advantage of multiple processor threads, making it ideal for dual-core CPU testing.



The results from this round are second only to the 3D gaming results in terms of AMD dominance. The only AMD processor that's slower than an Intel CPU is the Athlon 64 X2 3800+, but even that CPU manages to outpace Intel's lower-end dual-core chips, the Pentium D 830 and the Pentium D 820, in ripping an album to MP3 in iTunes, by 9 and 14 seconds, respectively. If you think that's bad for Intel, the difference between the Athlon 64 X2 4800+ and the Pentium Extreme Edition 840 is even worse, to the tune of a 23-second difference, or a whopping 20 percent.

How much more of a beating can Intel take? Will the referee need to step in and stop the fight?

Winner: AMD

Dual-core desktop CPU bout: AMD vs. Intel part2

2: Gaming

He who frags fastest, frags best.

3D gaming opens up a can of worms for performance testing because it's so commonly associated with 3D graphics cards. The processor does affect 3D performance, however. In order to test our CPUs' 3D capability, we created a so-called CPU-limited Half-Life 2 benchmark, which turns off all of the advanced graphics features, as to minimize the calls to the onboard graphics chip. This lets the CPU do most of the 3D heavy lifting.
Intel should be embarrassed with its showing in round 2. At every turn, AMD beat it to the punch. Even the Athlon 64 X2 3800+, the lowest end of AMD's dual-core CPUs, is better suited to 3D gaming than Intel's highest-end Extreme Edition 840 CPU, which lost by a full 10 percent.


That said, we should point out that games aren't really designed to take advantage of CPUs with multiple processing threads yet. We expect to see multithreaded games that will take advantage of dual-core CPUs sometime next year, at which point the 3D gaming results will need revisiting (there will likely be new chips available by then, as well). But for now, if you are a gamer in need of a dual-core rig, the only choice you need to make is deciding which Athlon X2 chip to pick up.

Winner: AMD

3: Multitasking

Our SysMark test gauges a processor's ability to work with a series of applications, but it doesn't really give us an idea of how well a CPU handles two intensive tasks simultaneously. That's where our multitasking test comes in. If you've ever run a virus scan on your PC (and we hope you have), you've likely experienced the swimming-in-molasses effect this process has on overall performance. But if you believe the marketing hype, dual-core CPUs are supposed to make virus scanning faster while letting you perform other tasks at the same time without delay.




To test dual-core CPUs then, we employ McAfee's VirusScan to inspect 40GB worth of files, while simultaneously encoding an 85MB video file using a program called Dr. Divx. We then time how long it takes each chip to complete both tasks. The results of our tests skewed heavily in AMD's favor (sensing a pattern yet?).

he best Intel could place on this test was fourth, with its $999 Pentium Processor Extreme Edition 840 chip coming within 4 seconds of the $507 Athlon 64 X2 4400+. It's also interesting to note that all three of Intel's Pentium D chips finished last on this test. As we saw in the last round with the gaming test, AMD overachieves to the point where even its budget Athlon 64 X2 3800+ chip outpaces Intel's second-fastest Pentium D 840. If you are like most computer users, you have more than one window running more of the time. And if you are like most computer users reading this story, you will draw the same conclusion as we have: AMD's Athlon X2 processors are the clear choice for superior multitasking performance.

Winner: AMD

Dual-core desktop CPU bout: AMD vs. Intel part1

You may recall a few months back when AMD took out full-page newspaper ads to challenge Intel to a dual-core server duel. Intel declined to take up AMD on its offer, but the challenge got us thinking: what would the results of a dual-core desktop CPU fight look like? Many people equate Windows PCs with Intel Pentium processors (and soon will likely be doing the same with Macs), but we've seen dual-core CPU AMD systems power ahead of dual-core Intel-based PCs on more than one occasion.

To answer the question once and for all, we circled up a bunch of cars in an abandoned parking garage and set ourselves to a no-holds-barred dual-core desktop CPU fistfight. AMD submitted its five dual-core CPUs, and Intel matched with its lineup of four. We built two test beds as nearly identical as we could for the two platforms and ran each chip through a battery of tests. We then ran those results through our price-vs.-performance calculator to find out not only which is the best overall dual-core CPU in terms of raw performance but also which one offers the most bang for your buck. Skip ahead to the official ruling if you want, but the match itself is interesting.

1.Day-to-day computing

Which chip delivers for the average Joe/Jane?

While dual-core CPUs are primarily meant for heavy multitasking and running multimedia applications, it's not like you're suddenly going to stop using Microsoft Word or other common applications when you sit down in front of a dual-core PC. Our first test, BAPCo's SysMark 2004 benchmark, gauges how well each chip handles the day-to-day rigors of standard office-productivity apps in addition to creating content for the Internet.

The test results are broken down into three scores: office productivity, Internet content creation, and overall. We primarily look to the overall score to determine our rating when we use SysMark for desktop testing, but the individual scores are particularly important if you're interested in buying a dual-core CPU for a specific task.
The results are clear: AMD lands a quick combination and takes the first round by placing two of its X2 processors at the top of the charts. Not only is its top-of-the-line Athlon 64 X2 4800+ faster than Intel's flagship Pentium Processor Extreme Edition 840 chip, but the Athlon 64 X2 4600+ also outpaces Intel's best. That result doesn't speak well of Intel's chip that costs $350 more than the X2 4600+.

The results scale similarly in AMD's favor as you move down each company's lineup. The X2 4400+ edges out its direct competitor, the Pentium D 840, for example. And at the low end, the X2 3800+ dispatches the Pentium D 820. For day-to-day computing performance, AMD's Athlon 64 X2 chips are the collective winner.

Winner: AMD

Amd VS Intel

AMD, long the oppressed rebel force in the chip industry, managed to launch an attack on the Intel Death Star with the introduction of its 64-bit Opteron processors in 2003.Opteron ran 64-bit applications and legacy 32-bit applications without the drag on performance noted in Intel's Itanium processors. AMD upped the ante further in 2005 with the introduction of its first dual-core Opteron processors that doubled the performance of single-core Opterons.

The first chink in Intel's armor appeared in the second quarter of that year when, as Mercury Research reported, Intel's market share slipped to 82.5 %, from 82.8 % in the year ago quarter, while AMD's inched up to 15.7 % from 15.6 %.

AMD further provoked Intel by running a newspaper ad challenging Intel to a processor duel, using the image of an AMD chip in a boxing ring.

AMD's share rose to 25.3 % in the fourth quarter of 2006, while Intel's fell to 74.4 %. Intel, while perhaps surprised, didn't take long to retaliate. Intel (2006 revenue, $35 billion) financed a price war with AMD ($5.6 billion) that pushed AMD into a pool of red ink, losing $2.1 billion over the last four quarters.

On the eve of the Barcelona launch, Bruce Shaw, AMD's director of server and workstation product marketing, said AMD may be battle-weary but is still in the fight: “If you look at the market as a whole it’s hard not to wax poetic about [how] we’ve brought competition to the market just by being here."

AMD Challenges Intel To A Dual-Core Duel

Live Shoot-Out to Focus on Server Workloads and Energy Consumption

SUNNYVALE, CA -- August 23, 2005 --In the spirit of fair and open competition, AMD (NYSE:AMD) today issued a challenge to Intel to conduct a head-to-head competition of dual-core x86 server processors. AMD’s proposed dual-core duel in 2005 would be a live, public performance evaluation between server platforms based on the highest-performing Dual-Core AMD Opteron™ 800 Series or 200 Series processors and the corresponding Intel x86 server processors that are commercially available in volume.

The challenge, issued today in The Wall Street Journal, USA Today, San Jose Mercury News and The San Francisco Chronicle, features the world’s first x86 dual-core server microprocessor, the Dual-Core AMD Opteron processor, in a boxing ring waiting for the Intel challenger. AMD has challenged Intel to settle the question once and for all—whose x86-based dual-core architecture best meets server customer’s needs.

“Since we launched Dual-Core AMD Opteron processors in April 2005, we’ve won every major industry-standard benchmark for x86 servers. AMD64 dual-core technology provides industry-leading performance, is easy to upgrade and is energy efficient,” said Marty Seyer, corporate vice president and general manager, Microprocessor Solutions Sector, AMD. “We are giving our competitor a fair and open opportunity to challenge our clear market leadership in a public setting. A head-to-head match using industry-standard benchmarks will arm customers with the information necessary to determine which company can best meet their computing needs. The gauntlet has been thrown down, it is time to cut through the hype, and demonstrate who the industry’s leader in x86 dual-core processing is today.”

Should Intel accept AMD’s challenge, the duel would take place at a public venue to be announced in the coming weeks, with testing conducted by a neutral, third-party testing lab. Testing would be done using industry-standard server benchmarks most relevant to customers today such as SPECjbb^® and SPECweb^® Measurement on energy consumption would also be conducted.

For more information on AMD’s challenge to Intel, please visit www.amd.com/duel. Stay tuned to this web site over the coming months for additional details on the duel, including an online petition to be launched in early September.

Rendering Performance

POV Ray is one of the oldest raytracing programs out there and it has been updated I don't know how many times since we started using it first in 1997. One of the issues we observed repeatedly was that the SSE2 render engine was slower than the standard version. WIth the 3.7 beta .21, this has changed, the standard version turned out to be markedly slower than the "formerly slower" SSE2 version. Due to the expiration of the older version, we show data obtained with the latest beta with the caveat that they may not be exactly comparable with the older results.

Media Encoding

Video and audio encoding are becoming increasingly important in the world of personal computing. Home-editing of videos and sound recordings are among the popular applications as is just the standard archiving of DVD material. In the case of audio encoding, there is relatively little out there in terms of applications that are multithreaded, meaning that they would take advantage of multiple cores. Or if there are appications like that, they are not free and the generally short conversion times achieved with free download utilities do not provide enough anguish to actually purchase potentially faster, multithreaded applications.For this article we used three applications that at least ran in the 80-85% CPU utilization when encoding audiovisual material, namely DVD-Shrink 3.2. Dr.DivX 2.0 OSS and the latest version of Mainconcept, namely H.264 Encoder.

In the case of DVD-Shrink we compressed John Grisham's "Runaway Jury" from 4,464 MB to 3,323MB, a compression to 59.6%. Dr.DivX encoded a 4.2 MB file (Watermellon.mpg) to a DivX file at Extreme Quality (thread priority: low) and Mainconcept encoded the same Watermellon.mpg file to an [H.264] High, 1920 x 1080 pixel, 29.97 fps, 48,000Hz 16 bit MPG file.

Conclusion

Intel once again came, saw and won and did so consistently by a landslide. The combination of DDR3, a new memory controller and the faster host bus interface turned out to be quite the "trio infernale", leaving the competition nothing but tears in their eyes. Rumor has it that the next generation Penryn CPUs will up the ante again over what we are seeing now, and the upcoming X38 platform will equally hit another homerun.

At this point, we cannot comment on products that have not been released yet. Fact is, though, that AMD will need a pretty gigantic leap to overturn the current market situation. On the other hand, it is not always top performance that counts, conservative power management and ultra-low pricing are the dominating factors in the bread and butter market.

All of that said and done, there is one last thing to do and that is to award Intel one of our coveted "Editor's Choice Awards". Well done!

Intel's Core 2 Quad Extreme Edition QX6850 and Core2 E6750 part 1

Intel is releasing its latest steps in evolution of the CPU, that is, the Conroe and Kentsfield cores souped up to run on a 1333 MHz bus interface. Combined with the latest P35 chipset and some fast DDR3, do the new kids on the block have what it takes to up the ante again?

Evolution of a Winner

There is hardly a shadow of doubt about who owns the desktop performance segment. Intel’s Core2 design has re-created the Caesarian motto Veni Vidi Vici by sweeping essentially every single benchmark that is out there, from gaming applications to rendering performance and encoding, whatever could be won was – indeed – won. Part of the Imperial Laurels have to be attributed to the quad-core offerings, like the Core2 Quad Extreme 6700 and 6800. Despite sharing the same host bus these quad core processors have managed to stay abreast of the competition, courtesy of highly sophisticated memory management that, regardless of the rather pedestrian values in synthetic benchmarks, appears to provide the correct data in sufficiently timely fashion. Needless to say, though that this is still one of the bottlenecks in the overall system architecture and this is where the new processors identified by a -50 as their last two product numbers promise some major improvement.

To make a long story short, Intel is doing three things simultaneously, each of which synergistically contributes to an overall increase in performance. The first thing is the introduction of a new, lower latency memory controller as part of the P35 chipset. The second factor is the introduction of DDR3 that finally overcomes some of the childhood maladies of DDR2. The third factor is what offsets the new line of CPU from its predecessors, they are running at a whopping 1333 MHz host bus interface. To be true, it is a 333 MHz clock and the bus is quad-pumped for 1333 MHz data rate over a 64-bit interface that in the final analysis is capable of transferring 10.67 GB sec from the system logic a.k.a. North Bridge to the CPU and vice versa.

The P35 Stop Gap

Before delving into performance issues, we would like to mention a few other things. The P35 chipset as it is almost common knowledge is only an intermediate chipset on the way to the next best thing coming from Intel, that is the X38 chipset. A lesser known fact is that aside from Intel, nVidia is also grinding the battleaxes by releasing BIOS updates for their nForce 680i chipset enabling 1333 MHz support along with future support for the Penryn core – for the time being with DDR2 support only but there is also a DDR3 version on the horizon.

CPU Details

Under the Hood of the Core2 Duo 6750 and the Core2 Extreme 6850 is nothing new, we have the same Conroe and Kentsfield processors that we already saw in earlier productions and that were largely responsible for re-establishing Intel's leading role in the performance desktop segment.
