AMD's Quad FX: Technically Quad Core

Gaming Performance with Quake 4 and Oblivion
Quake 4 doesn't show a huge deficit when looking at Quad FX performance vs. a single socket dual core AMD setup; there's a slight drop but nothing huge. Even though the latest version of the engine is multi-threaded, there's no real benefit above two cores. We will have to wait for the next-generation of titles before we'll start seeing real boosts in performance for quad core CPUs.
Oblivion performance is notably worse on Quad FX than with only a single socket AMD system due to the added memory latency. Now if you were running a 3dsmax render in the background, then the Quad FX system would be faster than its dual core counterpart.

If you would bother to read, you would see those IDLE numbers are Without C'n'C.Witch C'n'C the IDLE number is be more like 250W than 380W.

Hell, I should REALLY read after myself more thoroughly...JKing76 - Thursday, November 30, 2006 - link

I think it is safe to say Intel has caught AMD with its pants down this round with their Core 2 Duo line of products. Intels product line is much more compelling and performance\watt is scary good for Intel.Hell Intel's offering must be good, it got me to buy their product for the first time in nearly a decade! ;)

Actually not.AMD has caught Intel pants down in 2003. It took Intel 3!!! years to come back to game.
Those 3 yrs Intel was NOT price competitive.
Intel has just caught up in midle of 2006, this was to be expected and WAS expected by AMD.
AMD is about to catch up to Intel after 1 year..
This 1 year AMD IS price competitive, hence it is still in the game..
The 2008 Intel CSI may catch AMD with pants down. May.
Actually, in 2008 AMD will have some 30-35% marketshare and be so well entrenched in the corporate market that some mild performance(as now) hiccup is not gonna hurt them in any serious manner.

If you need quad-core/CPU system, kentsfield is a much better choice, no question asked.sprockkets - Thursday, November 30, 2006 - link
Why is it that just putting the other 2 cores on the same package reduces power consumption so much?Anyhow, yeah, Intel is ahead, though this would be good for servers, not for desktops. Even so, Intel for now is still better.
But, I found for perhaps 90% of all people, an old s754 board with a $45 dollar Sempron works fast enough. I wish Anand would check out the new C7 processor mini ITX boards to see how well it works for so little power consumption.

The QX6700 pretty much draws twice as much power as the E6700, the big benefit of going for quad-core in a single system is that you only have one motherboard, harddrive, one set of RAM sticks, one video card, etc. The 4x4 is horribly engineered, I think even 400W at load is too much for two Opterons at 3GHz.mino - Friday, December 1, 2006 - link
Two Opterons DO NOT employ 8000GTX usually ...Two Opterons do have 95W TDP(lower voltage) ... compared to 125W for FXs
Two Opterons are available in 68W TDP ...
Two Opterons are NOT available in 3GHz flavour ....
Two Opterons are twice as expensive ....

The 4x4 motherboard, that is...
