The AMD Athlon is taking this benchmark home! The 2700+ is beating the P4 pretty handily and so is the 2600+ processor. The difference here between the P4 and Athlon is about 13%.
The SiSoft memory scores here show us the difference between running DDR333 on a 266 FSB processor and the new 333 MHz FSB bus on the 2700+. With the added bandwidth on the processor we can now see the P4 is having a hard time keeping its head above the water where it used to stand tall above it.
This is the benchmark that shows off the key benefits of the improvements AMD has made on their latest processors.
Here, we can see that the added bus rate doesn’t help the integer or floating-point calculations of the Athlon – after all the 2700+ and 2600+ are virtually running at the same clock rate, and thus their scores are nearly the same. On the ALU side, the P4 is falling nearly 9% behind the Athlon XP line. On the FPU side, you can see on the graph that the P4 wins out over the Athlon by 15% or so. However, that score is with SSE2 enhancements running. Without SSE2, the P4 2.8 GHz scores a 1543, which is 95% slower than the Athlon XP 2700+.
