Intel Dual Core Test

Hi Guys,

got my hands on a P4 3.2GHZ Dual Core (D940 processor)

I took a Video File approx 48mins and run a final compile. It took 37mins to compile.

I run the same test on P4 3.0GHZ 478 Prescott and it took 49 mins.

I am hoping to run the same test tomorrow with VS10+

and with any luck get my hands on a Conroe to test as well.

Very difficult to make comparisons. A priori, compensating for processor speeds, passing from YOUR 3 GHz Prescott to YOUR 3.2 GHz dual core, you obtained an impressive rendering speed improvement of 24% with YOUR particular test file.

This does not mean that others would receive the same figures. Processor performance is not the be all and end all of video rendering times. There are many other factors that can influence the results, such as memory size/type/speed, FSB, chipset, motherboard design, CPU cycle latency, HT on/off, L1/L2 cache memories and even the type of file you are rendering, etc., etc., etc.

I upgraded from a prescott HT 3 ghz OC'ed to 3.7 over to a P950 and I notice a pretty good speed increase as well. I haven't put a stop watch to it yet, but is is definately fster.

I'm changing out my mobo as well (my existing one doesn't OC very well), but I expect with the new mobo I should be able to OC around 4.1 or so. But at any rate... the dual cores do make a difference.

Overclocking is not recommended for video work, as there are much longer periods of intense CPU and RAM activity than with, e.g., games.

I've been oc'ing for years with absolutely no problems whatso ever.
I run MSP, Studio, Liquid and a few others.... they all respond quite well.

I did have to install liquid cooling because of the higher temps though. Now I'm 38 degrees C at idle and 5o at full load

I'll be getting a new Core 2 Duo 6400 soon. It runs at 2.13 Ghz but can reliably overclock to 2.8 using stock cooling! This gives it comparable performance to the Core 2 Extreme, which is about $1200 more expensive.
Blitzes everthing AMD can offer as well. It's gonna be faaast.
