Core 2 Extreme Quad Processor Performance

Earlier in the week, Intel announced a single-socket processor built with two Core 2 CPU dies, the Core 2 Extreme Quad processor (code-named Kentsfield). The two dies connect via a 1066MHz (effective) front-side-bus (FSB). Intel claims that the FSB will have more than enough bandwidth to feed both cores, even if it is in heavy operation. Well, extremetech has got a hold of one and is comparing it to a Intel Core 2 Extreme X6800 processor, both of which are in identical machines, with the same motherboard, memory, video card and storage running Windows XP Prefessional Edition with service pack 2, running these performance tests, POV-Ray 3.70 beta 15, 3ds Max 8, DivX 6.25, and the 3DMark06 and PCMark05.

The full product name, as we noted earlier, is the Core 2 Extreme Quad QX6700. This is in line with Intel’s current naming scheme for CPUs, although they never called the previous Core 2 Extreme a “Duo.”

The CPU will clock at 2.66GHz with a 1066MHz effective FSB and may require a new motherboard. Intel noted that their new motherboard is an updated version of the D975XBX, which has been re-engineered to support the quad-core processor as well as DDR2/800 support. (Previous versions of the board would only support DDR2/667). It’s likely that some Intel 965P-based boards will also support the QX6700, but we haven’t received confirmation of that yet.

It’s likely that motherboards using the Intel 975X chipset and currently advertised as “Quad Core Ready” will work fine with the QX6700.

The QX6700 is rated for at 125 TDP (thermal design power), which is slightly less than the old Pentium Extreme Edition 965 CPU. However, unless you’re running four copies of Prime 95, it’s unlikely that all four cores will be running full-out all the time. Some of the boutique PC vendors have clocked the CPU up to 3.2GHz on air and 3.73GHz with liquid cooling. Source: ExtremeTech

Unfortunately, most of today’s PC games still tend to be single-threaded, so you won’t see much of a benefit initailly, maybe it it is a newer game, but that is changing rapidly, especially among game developers who are creating titles for pcs and the newer gaming consoles. Today’s game consoles require multi-threaded games, which mean PC games will be headed in this direction as well. But, while a gamer might not see as much improvement right now, 3d animation artists and video creators need to put back some money for it now, they will want one when they are available. Windows Vista will definately work well with a system containing one of these processors, a fast graphics card and high bandwidth memory, I can’t wait.
