Looks like the memory bandwidth enables up to perfect scaling on some applications. Of course, this is using Rambus memory, which some will agree is on its way out. On the other hand, Intel's dual channel DDR chipset called Springdale should be available by the time these faster speed parts are released next year. Vive la Competition, n'est pas?"At this point, here is an important announcements on the future top model P4/3600: there is a 29% increase in clock speed over the current top model with 2.8 GHz. The primary concern was how the increase in speed was reflected in the performance values. The result we got was that in all benchmarks, the CPU landed in first place by a long shot. The increase over the P4/2800 is between 7% and 29%, depending on the application. The biggest performance leap is with rendering applications, such as Cinema 4D XL, Lightwave 7.5 and 3D Studio Max 4.2. This means that performance increases linearly with clock speed gain - now that's perfect scaling! Smaller growth can be witnessed in MPEG-encoding tests, such as MPEG-1, MPEG-2 and MPEG-4. The lowest rise in terms of percent was with the 3D games (DirectX7 and DirectX8); here, the increase was between 7% (3D Mark 2001) and 15% (Comanche 4). It should be mentioned that these test results don't depend on CPU performance alone. In any case, the 3.6 GHz P4 scored the absolute best marks -- at Quake 3, for example, with 416 fps, or in the Sysmark test, with 328 points.In any case, the 3.6 GHz P4 scored the absolute best marks -- at Quake 3, for example, with 416 fps, or in the Sysmark test, with 328 points."
