Pentium 133 and RDRAM 533
Pentium 133 and RDRAM 533 much faster than single channel DDROK, to make the decision harder, even though RDRAM is "obsolete" and the main path is DDR, RDR 533 is a better choice for performance...
As of today, we have already tested the processors that Intel won't be bringing you until the fall of this year, at the earliest. Above all, this is related to the models Pentium 4/2666 and Pentium 4/2533, which are the first CPUs to offer support for 533 MHz Rambus. Our benchmark results clearly prove that if Intel changes the FSB and memory clocks (to 133 MHz and 533 MHz, respectively), this will put it quite a distance ahead of its competition from AMD, as well as its own series of processors. In the Office Performance category, the Pentium 4/2666 with 533 MHz RDRAM soars about 50% above the fastest AMD Athlon XP 2000 (VIA KT333 platform and DDR333). In MPEG-2 video encoding, the Pentium 4/2666 is approximately 25% ahead of the AMD Athlon XP 2000 (VIA KT333 platform). What's more, the P4 2666/533 achieves higher benchmark results than a P4 3000/400 in some categories.
Here, we'd like to make a general observation about the benchmark tests: used together with a 533 MHz memory clock, the performance of the Pentium 4 increases accordingly in all categories. By comparison, the growth in performance for the AMD processors, in conjunction with the VIA KT333 chipset, is relatively small. This fact is partially due to the DDR333 memory modules that we used, which did not work in CL2.0 mode. So, now it can already be determined that, in the future, AMD processors (Athlon XP/MP) will not make such big leaps in performance .
