Should I over-clock my Processor?

[-RK]

I know what hyperthreading is, and it is usually abbreviated as HTT for HyperThreading Technology.

HT is used for hypertransport which is used in AMD's socket 754 and beyond for bi-directional communication along the equivalent of a fsb, the hypertransport bus.

From what I know of P4 architecture, the primary limit of the CPU is in the bus. Having 2 seperate threads running on the same clock probably won't affect actual performance in application.

30% improvement of performance promised by intel. I've tried 3D Mark 05 to determine whether is there really improvement or not, I get only slight improvement, so it proved that getting 2 threads to run on a single core really did improved gaming performance, but not for applications. But after some overclocking, I'll get improvements of higher percentage. I've over-clock my processor to 4GHz, max load temperature is 60 dgrees (Worth getting the CoolerMaster Hyper TX2) , but not so sure about stabilty, still currently testing. If I have the money, I rather get a Core2 Duo rather than overclocking to compete with a Dual Core processor, but I know it's difficult because it's greatly improved by the additional SSSE3 instruction set.

A 3GHz single core perform better than 2GHz dual core in some games, because some games doesn't ultilize both the cores. I have this feeling that my P4 processor is powered by a single strong core and Dual Core has 2 weak cores working together

65/45nm architecture makes things smaller and more efficient.

The core2 solos perform at a level beyond the p4s. Good luck finding a solo anymore though, Dual-core cpus are much more future-proof.

That's why Cedar Mill perform better than Prescotts. Core2 series outperformed the P4s just because of the additional SSSE3 (aka SSE4) instruction set.

Even the original core solos (remember those?) outdid the p4s at a lower clock speed.

Because of the additional SSSE3 instruction set, Take PentiumD vs Core2 Duo as example, they are both Dual-Cores. But in gaming application, a 3GHz (for example) P4 can perform better than a 2GHz Dual-Core sometimes, anyway what's P4s maximum most stable temperature? I'm getting 68 degrees sometimes.....

You're running fairly hot, but you aren't in danger until you hit 75*C

The original core series did NOT include support for ssse3, though it was in later Pentium Ds when they started using Yonah in the PD. The 32 extra instructions in SSSE3 are only useful if the program can use them.

P4s have gotten to 5+ghz on good watercooling, but they don't see huge performance increases at that speed.

Some games don't support dual cores, and a dual-core won't exactly double performance. It also depends on what series of dual core. The pentium D's and core duos had really big memory latency issues between the cores.

The P4 prescott was known to run stable oc'd at around 80c and the cedar mill is safe at 72-73, so you're probably good with that. Only a stress test can really tell though.
