Multitasking Scenario 4: 3D Rendering

We received several requests for a 3D rendering multitasking test, so we put one together. For this test, we ran our SPECapc 3ds max 6 benchmark while we had iTunes, Firefox and Newsleecher all running like we have in previous tests. The application focus remained on Firefox to give it the highest scheduler priority, and the results are below:

3D Rendering + Multitasking Environment

Once again, we have one of those situations where the Athlon 64 X2 4400+ is more than twice as fast as the Athlon 64 FX-55. 3ds max is actually one of the best ways to guarantee that you exploit problems with Windows' scheduler in a repeatable fashion. In fact, part of the reason for such huge performance gains for AMD in SYSMark 2004 is this exact type of scenario caused by 3ds max not allowing the Windows scheduler to preempt other running tasks properly. The result here is that single core systems are basically horrendous in performance and system response, while all of the dual core systems actually let you get work done.

What's also interesting is that the performance of the Athlon 64 X2 4400+ is virtually identical with the Athlon 64 FX-55 from our standalone 3ds max test (1.65 vs 1.66). In this benchmark, the Pentium Extreme Edition 840 takes a pretty significant lead, thanks to HT. We see that even with a dual core CPU, there are still some issues to overcome with the OS' scheduler. So, we get an unusually large increase in performance due to HT due to the scheduler being tricked into sending more threads to the CPU rather than attempting to have them preempt one another for CPU time.

    i think what #130 was saying was that: from top to bottom, AMD's offerings are really good...if you want the best "bang for the buck" the 3400+ or whatever, or a 3000+ winnie OC'd will provide you with the best performance per dollar you spend...EVEN against the X2's.

    On the other hand if cost is not an issue, an X2 4400+ provides extremely good performance for people willing to pay the $500 premium.

    Zebo's point is in direct response to your point, which is AMD "STILL" has the best bang for the buck, not intel.

    or maybe YOU missed the logic? LOL

    "Intel is just lucky a 3400+ new castle wasn't in that test suite. It's would win the majority of tests over an 830!! and it's still cheaper. Or did you miss this chart? LOL"

    Why not just admit it. AMD's DC is about 10-20% faster while costing 80-100% more.

    Even if the 3400+ is added, that comparison is moot since if you compare the score of that to the price of AMD's own DC - the price performance ratio is stagerrring? Or did you miss that logic?

    Anyways did you miss the part that even AMD DC was being beaten by their own single core.

    Next.

    "The Athlon 64 4000+ was the last single core member of the Athlon 64 line.
    The Athlon 64 FX will continue as a single core CPU line, with the FX-57 (2.8GHz) due out later this year."

    Where did you get this info anand, i am not sure if an Athlon64 X2 4400+ could not coexist with a Athlon64 4400+. If this is the last 4000+ than i must say gee thats too bad....

    Techreports review is better for you. 64-bit OS, 64-bit apps when possible, no mystery unreproducable benchmarks like Anand's database stuff.

    Intels DC chips can hardy compete with AMDs single core offerings. Side by side both DC it's a joke.

    So ya, AMD still has the "best bang for the buck" top end to bottom end. And they a far on top of the mountain.

    Isn't the shoe on the other foot?

    For several years now, so many touted AMD's cheaper price and competative pricing.

    Now with Pentium4 D, especially with the 3GHz model, you get half the price of the cheapest X2 while probably at best 20% lower performance?

    What happened here?

    Now P4D 3GHz model is the best bang for the buck and not the AMD offering. This is a complete reversal of what a lot of AMD supporters have been touting?

    #125 Yeah, good point.

    Compare:
    A. singletreaded 32-bit app on a singlecore
    B. multi-threaded 64-bit app on a dualcore
    Considering that multithreaded apps already see such large gains on dualcores, going 64-bit too could well mean a more than 100% improvement from A to B.

    But of course, NO ONE needs dual core, 64-bit and +4GB memory in the next 5-10 years :P

    The ball now lies with MS and (Linux) app developpers to write more stuff in multithreaded 64-bit code. From what I hear and read it is not so much the 64-bit part as it is the threading that is a real challenge, even for veterans.

    Visual, On P.12 I was referring to the closest Xeon competitor to the 252s which is the Quad Xeon 3.6 GHz 667 MHz FSB.

    Does that make any more sense?

    jvarszegi, the actual stored procs are not prefixed with "sp_", we just used that as part of the "analogy" to the real system.

    One could also argue that we did not prefix the analogy example with the object owner either which also incurs a cache miss.

    Honestly, I have never quantified the expense of the sp_ prefix or the object owner.

    Where are the dual-core Windows x64 and Linux x64 benchmarks?? That's what I really want to see.
