Intel’s Quad-Core CPU delivers speed and power

Intel delivered their Core 2 Duo processor line in July which also delivered a surprise through the computer industry. The performance devotees who had been pleased by the performance of the Athlon 64 X2 CPUs had seemed to change their minds almost overnight. Additionally the message board is also full of posts arrogant on how they could push their E6300 CPU over the 3GHz. Currently it is AMD that is struggling. The company is looking anemic which was once noticed as swift and lean compared to the older juggernaut of Intel. The Sunnyvale, California based CUP Company would also not leave the competition so easily. AMD has already cut out prices from their own line of processors after Intel launched their Core 2 processor as the standard AMD system trends would be fairly less expensive. However, the price reductions have actually hurt the margins of AMD and the final thing the company would want is to be the second tier provider as they are back into the times when they were perceived as the second basis for Intel friendly CPUs.

Intel yet has something like their killer instinct they previously had, which fear that the ex-CEO had frequently proclaimed. Therefore Intel has launched their Core 2 Extreme Q6700 Quad-core processor. They are carefully built with 2 Core 2 Duo dies and this QX6700 is basically a 2 dual-core processor Cup that is packed single.  This makes it look like one processor as it is crucial for the licensing of operating system. Microsoft actually counts the hollows and not how many cores are used when licensing windows.

They have designed a system that uses QX6700 in order to find out if the 2 additional cores would really make any difference, but the result is as you would expect which is mixed. There are a few systems where it can make a clear difference while in other programs or applications you might hardly notice it. However when noticed in during the introduction for windows licensing purpose, the QX6700 actually looked a single CPU. The code name for this new quad core chip is Kentsfield which literally ties two dies that are built into the same multi chip module. This offers QX6700 a proficient die size of just 268mm sq that is double the size of single Core 2 Duo CPU.

There are also some other inferences for this approach, where both the dies offer 4MB of common L2 cache, but they are dedicated to the 2 cores on the same die. When you need to pass data forth and back between the cores it must be done through the 1066MHz SFB or shared front side bus. Intel suggests that SFB has ample of bandwidth to manage the kind of traffic that is used by desktop CUP. Some of the CPU architects still have some quires as a true quad-core basically consists of four cores on one die, but to this Intel had several reasons: The outcome is better for the pair of 143mm sq dies over the single 286mm sq die. It is also easier to bin-sort CPUs in order to get matched pairs for which the die with 2 mismatched cores will have to ship at a frequency of lower core. Lastly the key reason is faster time in marketing.
