Intel discontinues 13 processors

As the launch of the Core i7 generation is nearing, Intel is clearing the field in the product line-up. Intel grants the EOL status to 13 processors by the end of this year. The processors, under which eight dualcore and five quadcores, do not just include 65nm models, some of the 45nm 'Penryn' CPU's will also be discontinued already.

Production will stop on the 65nm E6850, E6750, E6650 and E4600 dualcores. In the 45nm line-up, the affected models are the E8300, E8200 and E8190. In the second quarter of 2009, the E4700 will also be removed from the line-up.

The first Yorkfield quadcore will go EOL in early 2009

Of the quadcores, the immensely popular Q6600 and it's big brother the Q6700 will be phased out in the first quarter of 2009. A remarkable thing is that Intel will already cancel the production on it's latest 45nm quadcores, considering the fact that their availability wasn't optimal until March this year.The first 45nm Yorkfield to clear the field is the Q9450, which will be followed by the Q9750 and QX9770 in the second quarter of 2009. These holes will be filled with respectively the entry-model Core i7 920 and the 3.2 GHz Core i7 965.

Intel Core I 7-940 REVIEW

The overclock performance data of bloomfield processors began to appear. Since core i7 processors are the representatives of the new nehalem architecture , the built-in memory controller will help to raise speed in the appropriate applications, the presence of hyper-Threading technology will allow to accelerate multi-threaded applications, but games can not demonstrate a explosive increase in comparison with core 2 Quad processors .

Associate reported some results which compare the processors core i 7-940 (2.93 GHz) and Core 2 Extreme QX9770 (2.93 GHz) in many applications.


Associates used the engineering model core i 7-940 (2.93 GHz), based on B0 stepping. It is completely possible that the series processors will show a higher speed level ; therefore results in question should not be assumed as final.

For simplification in the results analysis we give below the boost value in the selected applications after transfer from yorkfield to bloomfield processor:

• SuperPi - > 19.3%;
• WinRAR 3.71 - > 77.3%;
• Fritz chess benchmark - > 29%;
• Everest memory (Copy) - > 149,7%;
• CineBench - > 25.7%;
• TMPGEnc 4.5 - > 8%;
• 3DMark06 CPU - > 13.9%;
• 3DMark vantage CPU - > 50.5%;
• Half life 2-> 2.3%;
• World In conflict - > 6.7%;
• May's Devil Cry 4-> 5.1%.

In two games, Call of duty 4 and company of heroes, the processor core i 7-940 lose over their predecessor by 8.6% and 7.2% . In the remaining cases the confident superiority of this new architecture is observed. The intensive boost is observed in multithreaded applications memory bandwidth hungry application . Games, as it was assumed, demonstrate only a moderate increase in the performance.

Now here is the detailed info :

CPU :

* Intel Core 2 QX9770 (344x8.5=2.93 GHz ,12 Mb L2 Cache)
* Intel Core 2 QX9770 (400x8=3.2 GHz ,12 Mb L2 Cache)
* Intel Core i7 Extreme 940 (2.93 GHz , 8MB L3 Cache)

Motherboard :

* Intel X48
* Intel X58

Memory

* DDR3-1333Mhz 1GB x2
* DDR3-1333Mhz 1GB X3

Video card :

* Geforce Gtx 260 (576/1998/1242)

HDD :

* Seagate SATA 500 GB

Operating system and Driver:

* Windows Vista ultimate SP1
* Video Driver : Forceware 177.98
* Intel Chipset : 9.0.0.1011

Super Pi and winrar :

Intel Core I 7-940 REVIEW

Super pi is based on the processor cache (and memory for large calculation) while winrar love tide timing and high memory bandwidth , In both case the CPU power also play a large role . Winrar in this case do not miss the occasion to show the large gain from the integrated 3 channel memory controller (this will be confirmed also in memory bandwidth tests)

Core i7 overclocked to 4.2GHz

Because Core i7 Extreme has multiplier unlocked, so overclockers can easily OC to 4.2GHz by pulling up the multiplier. But like Phenom, the bus speed can not boost a lot. So we’d better drop our thought, they are not Core 2 anymore, so we may not have chance to see 500MHz+ bus speed.

If you read the everest benchmark chart and 3Dmark Vantage, the performance looks quite impressive.

Core i7 Incompatible With Performance DDR3 Memory

It looks like Intel’s upcoming Core i7 platform will have tight limits on the maximum DIMM voltages that can be safely used. According to information uncovered at the Inquirer, motherboard manufactures have been told by Intel that DDR3 memory when set to use voltages higher than 1.65V can burn out the CPU of upcoming Core i7 platforms.

Performance DDR3 memory that requires a voltage higher than 1.65V may permanently damage Core i7 CPUs.

Images of an unreleased Asus X58 motherboard in its apparent retail packaging show a sticker placed across the DIMM slots stating “According to Intel CPU SPEC, DIMMs with voltage setting over 1.65V may damage the CPU permanently. We recommend you install the DIMMs with the voltage setting below 1.65V.” According to the Inquirer, Asus had said it is safely running memory kits at 1.7V in its labs, but beyond that voltage you are on your own.

Intel’s upcoming Core i7 platform does not use a Front-Side Bus, making CPU overclocking essentially independent of the RAM. According to Fudzilla however, CPU and memory voltages on the Core i7 platform are synchronous, creating a potential limit for extreme overclocking if the CPU can only handle 1.65V safely.

What this also means is that consumers wishing to use current generation performance DDR3 memory with a Core i7 system may be in for a disappointment. Much of the performance memory currently available use a voltage greater than 1.7V, such as Patriot’s Viper 4GB 2000 MHz DDR3 memory that operates at 2.0V. It is expected that memory manufactures will release DDR3 memory kits designed for the Core i7 platform with some manufactures already announcing such plans. For example, A-Data’s recently announced a tri-channel DDR3 memory kit that operates between 1.65V to 1.75V and offers a latency setting of 7-7-7-20 2T for DDR3-1333+.

Unlike Intel’s Core 2 platform, the Core i7 platform uses triple channel memory, meaning memory kits designed for the Core i7 platform will come with three memory sticks instead of two. This fact alone might help prevent consumers from accidentally buying memory kits incompatible with Core i7 systems. Intel is expected to release the Core i7 platform in November for the upper mainstream, performance and enthusiastic markets.
