Battle 4: AMD vs. Intel

Coming to our fourth and final battle of this Doom 3 comparison we have the comparison we've all been waiting for, AMD vs. Intel. For this comparison we benchmarked quite a few different CPUs, all K7 based processors (e.g. Athlon XP, Sempron 2800+) are colored green, all K8 based processors (e.g. Athlon 64, Athlon 64 FX, Sempron 3100+) are colored orange and all Intel processors are blue in the graphs:

The first thing you'll notice is that the top of the chart is dominated almost exclusively by AMD Athlon 64 and Athlon 64 FX processors. Even the Athlon 64 3400+ manages to outperform the almighty Pentium 4 Extreme Edition 3.4, not to mention that the FX-53 distances itself from Intel's fastest by no less than 18%.

Making our way further down the chart we see that the Athlon 64 3000+ is quite possibly the best buy for excellent Doom 3 performance, weighing in right between the two Extreme Edition processors at less than 20% of the cost of those chips.

Next we have all of the Pentium 4s that manage to offer middle of the road performance under Doom 3, although we do see the K8 based Sempron 3100+ wedged in between the Prescott 3.2 and Prescott 3.0GHz CPUs.

Finally at the bottom we have the Athlon XPs as well as the lonely Celeron D, which is barely saved from a disappointing last place showing.

The standings remain the same at 1280x1024 as you can see below:

    The amount of System memory (above 512MB) is unlikely to have any impact on framerate in the timedemo as I doubt it would need to swap anything out after the first run (which is discarded anyway).

    I found my 128MB graphics-card (a Ti4200) gave an almost identical framerate at Low, Medium, and High quality settings in the timedemo even when gfx-card limited, provided Aniso was disabled in the driver for High quality mode (which would otherwise use 8x Aniso and impact on performance in other ways). So increasing the videocard memory from 128MB to 256MB will have no effect whatsoever on the timedemo, except maybe at Ultra quality which I didn't bother testing.

    That's the OS load balancing between the two procs. Two D3 threads aren't running at once. That's why sum utilization of both procs won't go over 100%.

    Is this review using XP or XP64 beta with the amd64 ? Are the benefits the same using a 32bitXP as opposed to the 64 bit XP ?

    its interesting how DOOM3 runs best in the Nvidia/AMD combo along with the amazing price/performance that they offer over their competitors

    the Athlon64 3000+ is on par with Intel's 3.4GHz EE, while the price difference is $840

    the GeForce 6800 GT is faster than ATI's X800XT PE, the price difference being $160

    so in this scenario, the Nvidia+AMD combo can save you $1000 and still outperform the ATI+Intel combo

    bottom line, for DOOM3 and future DOOM3 engine games, ATI+Intel=losers

    Yes, I would also like to see some numbers benchmarking 256/364/512/768/1024/etc MB memory configurations. When does the average system have *enough* ram to run WinXP and play a game? Reply

    Would it be possible to add the cache (and other) specs of the K7s to certain charts?
    Because sometimes the 2700 and 2800 are slower than then the 2500 and it'd be interesting to know why.

    Great article AT! I'm happy to know my 2.53Ghz @ 2.717Ghz P4 and 9800pro will happily run D3 at 8x6 in medium quality. I can now wait until HL2 at least to upgrade to whatever makes sense at the time (A64 something I imagine). Thanks again! Reply

    Great article, Do you plan to give an update with the high end ATI cards?

    Somehow, I feel ashamed that the Sempron 3100+ crushes my ol' P4 2.4C.... please please please stop publishing articles like this that encourage me to spend any more of my money upgrading to a new AMD platform to go along with my 6800. Reply
