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.

    So they say 5 years ago until now Intel was “all” crap. I think Northwood was/is very good.
    Sorry but the Netburst stuff is STILL garbage. Core 2 is head and shoulders better than anything they've made since the P3. Although, I thought the power consumption would be better.

    Man, some AMD fanboys just can't take defeat with dignity.

    Really expensive? Top of the line, sure, but funny you fail to mention the E6300 and E6600, which both offer far better value than the equivalent priced A64.

    Finally match (or even exceed by a few points)?
    OK, here is where I suggest you get your eyes checked out, or go back to school and learn to read graphs. C2D *spanked* A64, not 'match it or exceed it by a little'.

    I think you are just upset that AMDs days as performance crown are over. Tough life being a fanboy eh. You gotta take the ups with the downs son. ;)

    how is a $999 C2E hundreds of dollars more than a $999 FX-62? How is a 55% increase in performance "match (or even exceed by a few points)"? Perhap a slow reading of the article is need. Reply

    Intel has a hot chip on their hands here. Problem is, when will it have SLI available?
    And when will we finally see a review using an Nvidia chipset on the AMD side of this equation?

    newegg has started the conroe game by getting a $460 premium on extreme CD2

    errr......
    thats a rape of $360, not $460 - my bad (duh)

    It's not on the website anymore. I can't find any Conroe's up their at all. Non-existant. Also, and I know some of you read this but didn't AT say that the supply Conroe would be tight and would drive prices up until the end of the year? So why the bitching about higher prices? If Dell and others are buying up and making supply tight then prices go up. That's the way stuff is.

    Also, who has a Conroe other than the EE that we can buy today? Also, if these CPU's aren't available and today is the launch day then wouldn't this be considered a paper launch? And one more thing, where are the motherboards for this thing?

    technically a paper launch means there were none available at all on launch date. my understsanding is that there were some of these available, they have just been bought up. a limited supply is still better than a true paper launch, imho, even if the end result is the same for most of us - no product available to buy.

    This is a paper launch, and there's a variety of political reasons for it. Among the reasons:

    1 -- AMD is cutting their processor prices in a couple weeks, right after Core 2 Duo was supposed to launch. Intel wanted to launch first.

    2 -- People have been previewing Conroe performance for a while, because they got processors without going through Intel. Some were upset that they couldn't do articles because they didn't want to put in the time or effort trying to get a chip through other sources. By moving up the NDA lift date, Intel now allows all of the web sites to talk about Core 2 Duo in the open.

    Anyway, it's all a marketing war right now, and both AMD and Intel are guilty. Where are the Energy Efficient AMD processors? In about the same place as current Core 2 Duo chips. Basically, though, Intel is building up supply before the official availability launch as opposed to the NDA launch. We might actually be pleasant surprised by availability at the end of the month.

    How can it be a paperlaunch if they haven´t launched yet? Launch is still july 27th.

    Having sites test an upcoming product is a whole other matter.

    And just because some can buy B2 stepping retail Core 2 Duos from sites already shipping them means nothing.

    Here is a pic of a retail X6800 btw ;)
