Intel Pentium 4 2.8G (3)
Overclocker 25 Aug 2002

P4 2.8G registers an increment of 3.35% in performance over the P4 2.4G

P4 2.8G registers an increment of 2.17% in performance over the P4 2.4G

P4 2.8G registers an increment of 16.12% in performance over the P4 2.4G

Conclusion

The P4 2.8G has reclaimed the crown of the Gigahertz CPUs. While this race is heating up, both Intel and AMD definitely has yet to show us some of the secret weapons. One of the rumours is that AMD's future CPU will adopt a FSB of 166Mhz. We have seen that moving from 100Mhz FSB to 133Mhz makes quite a difference in the performance of the system, so will the shift from 133mhz to 166mhz makes it faster if enhanced with a 512K L2 cache?

On the Intel front, we should be expecting newer chipsets coming from Intel and SiS. In fact, the current fastest platform for P4 is the 850E+RIMM4200. SiS also has a SiS R658 chipset which is on the pipeline. We have already seen that and there is no doubt if the i850E + RIMM4200 (512M) is paired up with P4 2.8G, it will leave AMD 2600+ further behind in the performance race. There is also the upcoming Dual Channel DDR chipset from Intel by the technical model name of "Bay at the Rock". This is something we are looking forward.

In conclusion, what I want to say is that the performance of a system is not entirely reliant on the CPU but it also relies on the chipset and the mainboard design. The drivers involved also plays an important role in the resulting performance levels. The supporting peripherals will also increase the overall performance if the applications are I/O intensive. 

* We are unable to post detail results of AMD 2600+ as AMD never send us CPUs. Drop them a mail if you want OCWorkbench to be able to test out the latest CPUs from them.
