Intel's Core 2 Extreme & Core 2 Duo: The Empire Strikes Back

CPU Bound Gaming Performance
While we always try to run our gaming benchmarks in CPU reviews as a balance between being CPU and GPU bound, there is some merit to using CPU bound gaming scenarios as a true measure of the gaming power of a CPU.
The previous pages of gaming benchmarks were run at 1600 x 1200, which struck a good balance between being CPU and GPU bound on our CrossFire setup but here we’re looking at exactly how good of a gaming CPU the Core 2 Duo is. By running these tests at 640 x 480 with the same CrossFire setup as before we’re ensuring that the performance bottlenecks in these titles shift as far as possible from the GPU and onto the CPU.
These tests aren’t designed to tell you how fast these CPUs are at running these games, but rather how quickly they can run through the physics and AI code when not waiting on the graphics card at all.
We chose to look at two CPUs: the Core 2 Extreme X6800 and the Athlon 64 FX-62, to get an idea of how strong each architecture was at pure physics/AI processing in games. We also omitted any games whose performance didn’t change by dropping the resolution from 1600 x 1200 to 640 x 480 (meaning that those games were already predominantly CPU limited in our previous tests).
| CPU | Quake 4 | HL2 Ep 1 | F.E.A.R. | BF2 |
| AMD Athlon 64 FX-62 | 156.7 | 170.0 | 164.0 | 108.7 |
| Intel Core 2 Extreme X6800 | 192.5 | 263.5 | 236.0 | 142.3 |
| Advantage (Intel) | 22.8% | 55.0% | 43.9% | 30.9% |
In terms of sheer ability to process physics and AI as well as feed a hungry graphics subsystem, Intel's Core 2 Extreme X6800 is anywhere between 22 and 55% faster than AMD's Athlon 64 FX-62.
While this doesn't mean much for real world gaming, it does cement the fact that Intel's Core 2 processor is significantly faster at the type of code current 3D games will throw at it. The very same benchmarks that Intel used to complain about favoring AMD, now favor Intel just as much; oh how times have changed.

This is a bit more complicated - you could buy a $1000 FX-62, or you could buy a $316 Core2Duo, then a $150+ mainboard. If you want to run SLI, you are out of luck right now - but things might change in the immediate future. If you have NVidia SLI, you must go to Crossfire (at this moment).But anyway, looks like AMD can not compete in the top

Since the P6!!!! Makes me think if AMD actually cares about improving performance on their processors. Maybe they should scrap the Fab in New York and make a research facility instead. Start hiring interns from MIT. Do something! lol.I admit, even though I enjoyed AMD having the performance crown, It was a period of limited choice and limited performance gain. Who here on the free market care about 100MHz increaments? They went from a 110nm to 90nm with no performance benifit - they went from single core to the dual core X2's with no performance benifit -- they went from DDR to DDR2 with no performance improvement -- now they are going to 65nm which they also made clear they will make no changes to increase performance. AMD has really dropped the ball and they deserve what they get. I don't know why anyone, including over clockers, would want to be a AMD fan boy at the momment.

AMD went from single core to dual core with no performance benefit?Maybe on Planet Troll...

The X2 improved performance only on specific suites of software. Can you say the same about Conroe? I mean I was really able to crank up the rez in oblivion after I upgraded to an X2 *rolls eyes*.JarredWalton - Friday, July 14, 2006 - link
The performance increases you're seeing in most games on Core 2 Duo come entirely from the better architecture, not from dual processor cores. We just can't test single core performance on Core 2 because such chips don't exist and they won't until Conroe-L ships (in about a year judging by road maps -- it looks like Intel and their partners want to have time to clear out all of their NetBurst inventory first).Regs - Friday, July 14, 2006 - link
Yes, I completely agree. The only difference on the X2 compared to the single cores was encoding. Not unless you do own a 10-thousand dollar server for well...server use.Calin - Friday, July 14, 2006 - link
Being a fanboy is like a religion - you don't change your religion overnight.AMD cares about selling expensive processors. As long as the P4 was the opposition (especially after the Northwood days), AMD was king of hill, and sold its processors at whatever prices the market would pay. Now, Intel took that place. I hope this will change with K8L, as this will bring even lower prices for even better processors.
Also, AMD was unable to produce enough processors, so they sold most of it for a premium. As for the move to 90nm, they got some extra frequency headroom, and lower power consumption. This also reduced their costs (too bad the cost reduction wasn't really passed to customers).
If their move from single to dual core brought no performance benefit, tell that to companies buying dual core opterons for thousands dollars apiece.

Good lord. You might as well throw up the GAME OVER and TILT signs for AMD right now. Although I wouldnt want them to disappear from competition (I dont want us to return to expensive Intel cpu's at the same time) there isnt much I see in this article that gives AMD any advantage at the moment over Intel. Sooner or later this was bound to happen from Intel though, the Athlon 64 made a similar situation against Pentium 4 making it look pretty obsolete comparitavely at the time.Now assuming the prices that AMD plans to drop to are correct, perhaps they can remain compeditive for building a budget system vs. Core 2 as I would not recommend a new Pentium 4 at this point to anyone...
That reminds me of the good ol days over overclocking the Celeron A...
dice1111 - Wednesday, July 19, 2006 - link
Ahhh, yes. My old Celeron A (still overclocked and in use). I was so happy about overclocking back then. Please Intel, let me get that taste of nostalgia!!!mobutu - Friday, July 14, 2006 - link
I'd really like to upgrade to Conroe but I don't want the Intel chipset on motherboard.Jarred, Wesley, do you know (estimate) when you'll have a review with final 590 reference board and when we can expect motherboards with 590 Intel edtn to be available?
Thanks in advance guys. Great Conroe review.
