Intel E6750 Conclusions

On all our tests Core 2 Duo E6750 performance was identical to Core 2 Duo E6700, even though it uses a faster front side bus – and we simulated the use of several different types of application.

So what is the advantage of using a Core 2 Duo E6750 instead of a Core 2 Duo E6700? Based on the results from our tests, none.

Then why Intel is launching this new 1,333 MHz external bus? We have two answers for that.

First, on quad-core CPUs the higher external clock rate may increase the system performance. This happens because currently on Intel quad-core CPUs the cores are arranged into two pairs. The cores inside each pair can talk directly to each other, but if they need to talk to a core that belongs to the other pair they need to go to the front side bus and make this connection going thru outside the processor. Increasing the CPU external clock rate increases, at least in theory, the speed each core pair can talk to each other.

We will have to wait until we review a quad-core CPU based on this new FSB to see if this is really the case.

The second reason we can see is regarding DDR3-1333 memories, which will be supported by the Intel X38 chipset to be launched in July. Using DDR3-1333 memories with a Core 2 running externally at 1,333 MHz you will be able to match the FSB clock with the memory clock, allowing you to achieve the maximum performance with current technology.

In retrospect we must keep in mind that this is the first time in six years that Intel is launching a new front side bus speed with memories matching it. When the Pentium 4 was launched, for example, it used the then-new 400 MHz FSB and there were no 400 MHz memories at the time – this was PC-100 times and DDR-400 wasn’t available yet. The same thing happened when they launched the 533 MHz, the 800 MHz and even the 1,066 MHz external clock speeds. Even to this date Intel chipsets do not officially support DDR2-1066 (even though Intel P965 and P35 can access memories at 1,066 MHz just fine and P35 officially support DDR3-1066). DDR3-1333 availability may be an issue, but that is a totally different story.

Features:

Dual-Core Processing	Two independent processor cores in one physical package run at the same frequency, and share up to 4 MB of L2 cache as well as up to a 1333 MHz1 Front Side Bus, for truly parallel computing.
Intel® Wide Dynamic Execution	Improves execution speed and efficiency, delivering more instructions per clock cycle. Each core can complete up to four full instructions simultaneously.
Intel® Smart Memory Access	Optimizes the use of the data bandwidth from the memory subsystem to accelerate out-of-order execution. A newly designed prediction mechanism reduces the time in-flight instructions have to wait for data. New pre-fetch algorithms move data from system memory into fast L2 cache in advance of execution. These functions keep the pipeline full, improving instruction throughput and performance
Intel® Advanced Smart Cache	The shared L2 cache is dynamically allocated to each processor core based on workload. This efficient, dual-core optimized implementation increases the probability that each core can access data from fast L2 cache, significantly reducing latency to frequently used data and improving performance
Intel® Advanced Digital Media Boost	Accelerates the execution of Streaming SIMD Extension (SSE) instructions to significantly improve the performance on a broad range of applications, including video, audio, image and photo processing, multimedia, encryption, financial, engineering and scientific applications. The 128-bit SSE instructions are now issued at a throughput rate of one per clock cycle effectively doubling their speed of execution on a per clock basis over previous generation processors.
Intel® Virtualization Technology (Intel VT)	Intel® VT allows one hardware platform to function as multiple “virtual” platforms. For businesses, Intel VT offers improved manageability, limiting downtime and maintaining worker productivity by isolating computing activities into separate partitions.
Intel® Trusted Execution Technology (Intel® TXT)	Intel® TXT provides hardware-based mechanisms to help protect against software-based attacks and help protect the confidentiality and integrity of data stored or created on the system. It does this by enabling a trusted environment where applications can run within their own space, protected from all other software on the system.
Intel® 64 Architecture	Enables the processor to access larger amounts of memory. With appropriate 64-bit supporting hardware and software, platforms based on an Intel processor supporting Intel 64 architecture can allow the use of extended virtual and physical memory.
Execute Disable Bit4	Provides enhanced virus protection when deployed with a supported operating system. The Execute Disable Bit allows memory to be marked as executable or non-executable, allowing the processor to raise an error to the operating system if malicious code attempts to run in non-executable memory, thereby preventing the code from infecting the system.
Intel Designed Thermal Solution for Boxed Processors	Includes a 4-pin connector for fan speed control to help minimize the acoustic noise levels generated from running the fan at higher speeds for thermal performance.5 Fan speed control technology is based on actual CPU temperature and power usage.

Intel Core 2 Duo E6750 Preview

Introduction:

You've gotten the upgrade itch again. Your system is up to date, you have a dual core processor already, but that hardware jones just won’t go away. Kind of like the new car itch. You get in and smell the newness, kick the tires, and the salesman leads you down the hallway to the finance room to talk to the numbers guy. Then you finally put your name on the dotted line and you are now the proud owner of a new car. On the way home the buyers regret starts. By the time you get home, you start to realize that the other car was still pretty nice. You won’t have to sign on the dotted line and promise out your first born child to be able to own one of Intel’s latest Core 2 Duo CPUs. In fact, with the latest price drops, they are downright affordable. For the Average Joe, 2.66 GHz, 1066MHz and 1333MHz are numbers that really don’t mean a whole lot.

For the enthusiast, those numbers bring the hope of increased performance and higher clock speeds from the CPUs that we chose. Intel’s latest Core 2 Duo CPUs feature a 333 FSB instead of the 266 FSB we have grown accustomed to. Built using the same 65 nanometer process as its predecessors, it includes a shared L2 cache of 4 megabytes with 64 bit support on a socket 775 platform. Many motherboards currently on the market have the capability to use these new CPUs, while some need just a simple BIOS update to gain the capability. So why not jump in and take a look while we see what the latest from Intel has to offer.

Intel was formed at a time when the average size computer took up a large amount of space, usually several rooms. My how times have changed. Now the heart of a computer can be held in the palm of your hand with no thoughts of being crushed. Intel has lead the way with innovation and continually reducing the size of the processor and increasing the level of performance.

Installation:

The installation process is slightly different from many processors that have been produced. With the 775 socket, Intel has migrated away from using pins on the bottom of the CPU to make contact with the socket. Instead of the pins being on the processor, the pins are spring loaded in the socket and the contact surface on the CPU is just a flat circular disc. This eliminates the fear of bending a pin if for some reason you drop the processor or it was handled roughly during shipment. While this is a change, it is for the better in my opinion.

Installing this processor into the motherboard is no different than any other socket 775 Intel processor. You will want to start out by opening the hold down mechanism. Lift out and up on the retention arm to release the hold down mechanism. Then lift the hold down plate and insert your CPU, making sure you index the processor into the socket using the two notches on the socket and processor as your guide.
