Audio/Video Encoding

Not all audio encoding applications are multithreaded, and thus, we don't see overly impressive performance here from the X2 4400+. That being said, the X2 is at least competitive with its faster single core relatives.

DivX 5.2.1 with AutoGK

Armed with the DivX 5.2.1 and AutoGK 1.60, we took all of the processors to task at encoding a chapter out of "Pirates of the Caribbean". We set AutoGK to give us 75% quality of the original DVD rip and did not encode audio.

DivX Encoding

The days of AMD losing the encoding comparisons are over - the Athlon 64 X2 4400+ offers encoding performance that rivals the Pentium D 840. Unfortunately at the sub-$500 level, AMD remains fairly non-competitive in encoding performance.

XviD with AutoGK

Another very popular codec is the XviD codec, and thus, we measured encoding performance using it instead of DivX for this next test. The rest of the variables remained the same as the DivX test.

WMV9 Encoding

The Athlon 64 X2 continues to dominate in encoding performance in our own Windows Media Encoder 9 test.

    Anand, great reading as always.

    I have an observation:

    On the 'Development Performance - Compiling Firefox' section you write
    "This particular test is only single threaded, ..."

    Why not launch a multithreaded build?

    "make -j3 -f client.mk build_all"

    Makes good sense for AMD to keep their (server) dualcore chips pricey. AMD has limited manufacturing capacity, and they have best singlecore solution. In other words, they might as well keep the dualcore prices high, to a) make more money in cases where people are willing to fork over lots of money, and b) keep people who are on a budget interested in their singlecore offerings, at least until their new fab goes online.

    I have some comments about the Firefox compile test. First, thanks alot for including it. Now I have some comments about it. First, you are using GNU make and it supports parallel compiles. So, you should be able to replace the line:

    make -f client.mk build_all

    with the line:

    make -j 2 -f client.mk build_all

    to perform a parallel compile using 2 processors. The -j option specifies how many processors or threads you are using. You can do parallel compiles on a single processor machine as well as multi-processor or multi-core machines. It is often the case that using -j 2 or -j 3 on a single processor machine will give the best results because of it's allowing the overlaping of cpu computations and I/O.

    You don't say whether you did a debug or optimized build. I would recommend doing both the debug and optimized builds and reporting the results of both. When doing parallel optimized compiles, you may want to make sure you are not swapping although for the server tests it looks like you have plenty of memory - 4 GBytes. I did not see immediately how much memory you were using for the X2 tests. Anyway, I would recommend doing both debug and optimized compiles with -j n where n is 1, 2, 3, and 4 or perhaps just 1, 2, and 4. Since compiles are essential to development work and also embarassingly parallel, this should provide a really good comparison of the multitasking capabilities of these systems.

    Hope you can do this or at least some of it and thanks alot for adding a really good compile test to your test suite.

    The server market is where AMD is going headed to get large margins in their chips. With Supermicro joining the AMD camp (they must have seen the performance of the Opteron dualcore, blinked their eyes and said, "we're in") Dell is left alone holding Intel only product lines. Intel will not have a response on the server front until Q1 2006. That is troubling for Intel because it give AMD six months of market buildup and Fab36 time to come online and increase volume tremendously. It should be interesting.

    Imagine a 4800+ on a 939 DFI board running at 2-2-2-8 1t timings versus the P4 Extreme dualcore. Drooling just thinking about having either processor, but especially the AMD

    "AMD would probably have problems delievering a lower cost dual core in quantities ."

    This is exactly it. Why should AMD let demand outstrip supply? Just jack up the price until you've got just enough demand to consume your supply.

    I mean, yes, I'd love an Athlon64 X2 5000+ with 1mb of cache for ~$250, but that's life. AMD stockholders should be pleased with this decision.

    There's also the impending move to socket M2 to consider... the Athlon64 X2 makes sense for people with very low-end A64's, but M2 is going to be the better upgrade path for FX and/or 3800+ users. I would be surprised to see any 939 Athlon64's past 5200+.

    While our desires as desktop users are for high volumes of X2s at low prices, we have to balance that with what AMD as a company needs to survive...money. AMD is currently capacity constrained with regard to dual-core CPUs with only Fab30. They have entered into agreements with both IBM and Chartered for additional capacity (probably on the lower end chips), but that won't come online until late this year. Just before production starts to ramp at Fab36.

    In the meantime, AMD has stated that their order of priority goes Server -> Mobile -> Desktop with the profitability motive in mind. For most users that will be heavily into the multi-tasking benefits of dual-core CPUs, spending $5xx for the low-end X2 vs $1000 for the PEE 840 will be a no-brainer. Seeing how that is a small minority of users, AMD can reasonbly supply the demand for them while still maintaining the highlest level of availability of dual-core Opterons at much better ASPs. Remember that AMD wants to capture as much market share in the server market as possible while Intel has no response.

    As a share-holder, I hope that the demand for dual-core Opteron is deafening based on the incredible price/performance ratio (thus limiting their ability to produce X2 in high quantity). As a middle-of-the-road desktop user, I'm quite content with my mildly OC'd A64 for the next year or two.

    w00t! Ill have to read it later tho...

    Certainly impressive.

    I think it is important to remember that the "Athlon64 X2" was actually an Opteron running ECC RAM at 2T on a less-than-stable motherboard. I think it is best think of this as a comparison of Intel's dual cores, AMD's single cores, and a hog-tied Athlon64 X2.
    Makes you wonder how an actual X2 with fast memory on a fast motherboard will perfom.

    Regardless, I'm really excited about the upgrade potential, and I hope that AMD sticks with socket 939 for a long while.

    Great review Anand...Thanks for fixing your gaming bar charts...they were wacked before!

  • Tapout1511 - Thursday, April 21, 2005 - link

    Sure would have been nice if they had included a single core A64 at 2.2GHz w/ 1MB cache (3500+ right?) to illustrate instances where the extra core was useful and when it wasn't.

    Oh well.
