Gaming Performance using Quake 4, Battlefield 2 & Half Life 2 Episode 1
We will wrap up with gaming performance benchmarks. If you expect to find something exciting with the currently available software, prepare to be disappointed. There are slight variations in the benchmark scores, but most differences can be accounted for by the margin of error in running each test. Even those applications which do have rudimentary SMP support show no advantage from having more than dual cores.
As an example, our understanding is that the threading approach used in Quake 4 consists of separating the client and server threads and running each system as a separate thread. This is known as coarse grained threading and it represents one of the easiest approaches to making an application multithreaded. Unfortunately, as is the case here, coarse threading often results in limited performance improvements. A system is only as fast as its slowest component, and in the case of Quake 4 the client thread still does the vast majority of work, including all the graphics and sound rendering. The end result is that even with high-end graphics cards, you still quickly become GPU limited.

What do you mean it is "a insanely round-about way of measuring power draw"? Can you come up with a better one that doesn't involve cutting tracks on mobos to read the current being passed through them? Or a method which would work equally well with very soon to be released G80 graphics-core which is reputed to dissipate rather a lot of heat (clamp the water-block on that G80 and we'll soon see how much heat it really puts out).If you can come up with a simpler and better method of determining the power usage of CPUs and other devices, feel free to divulge the details here because their current method of measuring at the AC power-outlet is woefully inadequate, and I think a water-block heat-transfer system is not only a simple but quite accurate way of measuring power use, but one that can be applied to both CPUs and GPUs.

Wow, all you guys have really weird methods of measuring power draw. Nearly all the power for modern processors comes through the 12V Aux power connector. You can measure the current and voltage here and you will get the power consumption of the processor. However, the efficiency of the VRM can skew the results slightly.Gigahertz19 - Thursday, November 2, 2006 - link
Ah I like the little hint on the transitor count for Nividia's G80 when they release next week. Can't wait till Nvidia's G80 is released and we get some benchies :)

Looking at pure encoding performance we can expect only 40-50% increase.It is very,very bad.
Why don't you compare this CPU with Dual-Core Opteron platform?
Without better cache management this CPU is only for benchmarks same as 4x4 it's with crazy pricing.

Why compare cheaper single-socket platform with more expensive dual-socket platform?
Are you kidding? Kentsfield PC will be cheaper than 4x4 PC, if Kentsfield will achieve same level of performance, then it will have better price/performance ratio.

Damn.. I can't get over how gigantic those dice look together.msva124 - Thursday, November 2, 2006 - link
Is the article fully uploaded yet? I got some 404s as I was reading through it.xFlankerx - Thursday, November 2, 2006 - link
Fine for me now. NIce stuff too, as has come to be expected from AT.Chuske - Monday, December 25, 2017 - link
I come from the FUTURE !! In very late 2017, beggining of 2018, quad core CPUs are still very much in use .. even QX6700 and people favourite Q6600 (10$ now) held pretty well, for 11 yo cpus ..
