Here you can see that the added bandwidth on the processor bus gives the 2700+ a slight advantage in the ScienceMark test. The P4 results show it being a bit under 4% slower than the Athlon XP 2700+ setup.
The Cachemem results are a bit mixed as the P4 setup takes the Read test by a hefty margin of 12%. On the other hand the write test shows the Athlon XP 2700+ winning by over 20% and leaves the P4 on the same level as the 2600+ and 2000+ AMD setups
The newly updated SPECviewperf 7.0 has similar tests but is supposed to be less partial towards any particular architecture of processor or graphics card. On all of them we see that the Athlon XP 2700+ processor takes the crown. The P4 has a good showing coming in second on nearly all of them as well, and rather close on the Light and UGS tests.
