| Pentium4 2.4 GHz Another Turning Point | |
| (Review by MS, April 8, 2002) |
Test Platform
Since our last P4 review, quite a few things have changed, the SIS 645 has become a real production platform and the GeForce4 has been introduced as well. In other words, we are looking at an entirely different platform.
At One Glance
The highest we were able to run the CPU stable was 120 MHz FSB for 2880 MHz clockspeed, however, this is with the caveat that most of the time the CPU would not initialize at this speed. At 118 MHz there were no real problems, however, for ultimate reliability we went bach one more MHz to 117 MHz where the system would run absolutely reliable, even with the memory bus set to a 3:5 ratio (194.5 MHz)
Synthetic Benchmarks
Sisoft Sandra
Memory benchmarks are more an issue with the chipset or the particular board in question and have little to do with the CPU itself, we'll leave those for a full review of the ASUS P4S333 within the next few days and concentrate on the CPU integer and floating point performance here.
Arithmetic CPU Performance
2.808 GHz (117 MHz FSB)
SiSoft Sandra Arithmetic CPU performance at 100 and 117 MHz FSB. As you can see (of course you cannot which is implicit by this phrase), the performance scales in a perfectly linear fashion with clock speed as it was not expected otherwise.
SiSoft Sandra Multimedia CPU performance
In the multimedia benchmark, the picture repeats itself.
2.4 GHz (100 MHz FSB)
2.808 GHz (117 MHz FSB)
SiSoft Sandra CPU multimedia performance at 100 and 117 MHz FSB. Again, we find an almost perfect match with the expected performance increase.
