2.0GHz Today, 2.5GHz Tomorrow

At the last minute, AMD informed us that we'd be receiving three sets of Barcelona processors: a pair of 1.9GHz chips, 2.0GHz chips and 2.5GHz chips. The latter won't be shipping until Q4 of this year, but AMD wanted to show that Barcelona is yielding at higher clock speeds and that there is a roadmap going forward.


Barcelona - 1.9GHz


Barcelona - 2.0GHz

To be honest, we expected 2.5GHz by the end of year from AMD, and slightly higher on the desktop but it's good to actually have silicon in hand instead of empty promises or hunches.


AMD taking notes from Intel, hand written clock speeds are in.

With 2.5GHz in hand today, we'd expect Phenom to be at or below 2.6GHz by the end of the year, with 3.0GHz coming sometime in 2008.

    Good catch, thx. Even though I said 'lower is better', I swapped it in my mind.
    So K10 looks much worse than K8 single core in that test.
    I wonder where that penalty comes from and if it will pronounced in other apps.

    I have a question about RAM types. Are the slots different for normal unregistered DDR2, registered DDR2, and FBDIMM DDR2?

    If any of those are the same slots, what happens if you mess up and put the wrong type?

    And I also have a suggestion for you Anand. Try testing with ASUS L1N64-SLI WS motherboard. It is originally for the QuadFX line of processors from AMD, but apparently the old K8 socket-f opterons work just fine in it, with unregistered DDR2. I assume the newer Barcelona opterons will too.

    Good preview Anand...
    Nice closing summary that put's it in a nutshell.

    Too bad you couldn't drop a q6600 into that socket instead of just a k10 for a comparison that we all are looking forward to. ;)
    Considering it isn't coming to desktop for a while, no biggie, it will be compared when it matters.

    What is the huge deal in AMD not being able to get to high frequencies, I don't understand?
    3ghz was in range many years ago for Intel, AMD still has difficulty getting parts out at 3Ghz. I lack the understanding if it's just manufacturing limits/costs or is it more due to their architecture limitations (interconnects and such).

    quote:

    The trouble for AMD this time around is that Phenom is a much larger chip than the outgoing Athlon 64 X2, whereas Intel's Penryn family will actually be smaller than Conroe. AMD is already losing a considerable amount of money each quarter, so fabbing a larger chip at the same price as current CPUs will only make the situation worse. However, Intel can afford to continue to keep its processors as aggressively priced, especially moving to 45nm.

    To put it plainly: Phenom/Barcelona make this price war more difficult on AMD, while Penryn makes it easier on Intel. What's the end game? Is there a solution?


    This is the part that is really scarry. Intel who had profits in the 5bil range last quarter, can literally drive AMD into the ground by outpricing and outperforming them. Even if Intel decides to start losing money with a hugely aggressive price/performance ratio that is hard to pass up, AMD would not be able to withstand that onslaught for long...Question is does Intel have the blood lust to ring the death knoll once and for all and try to drive them into the ground. The saving grace here really is the high end server market with 2 and 4 socket configurations(8,16 cores) where Barcelona will stretch it's legs over Intel.
    I hope for the best!

    Intel could do that, but they're not going to. AMD has to stay in business, because Intel can't afford to become a monopoly. However, Intel doesn't have a problem putting AMD on life support.

    It's a scary time for AMD.
  • MadBoris - Monday, September 10, 2007 - link

    Hehe, good point. War of attrition. Break down their supply lines and lower their profits in such a way that they can't afford to do extensive R&D to innovate technology. Keeps them hobbling near by, but not as dangerously competitive.
    Intel can even make themselves "appear" more superior as a company by comparison to their runner up, and yet all the while they are innovating at the same pace they always were and not all that better, just have the appearance of greater superiority.

    You might just shoot yourself in the foot if and when AMD brings out the Sledgehammer.
  • leexgx - Monday, September 10, 2007 - link

    thay did it was an K8 for 3 years but then Core2 came with its Sledgehammer

    taken AMD to long to bring there new cpu out

    I compared the performance scaling between Barcelona and Core 2 Quad where Anandtech has run the same benchmarks. The C2Q results are taken from http://www.anandtech.com/cpuchipsets/intel/showdoc...">this review:

    The CPUs used are Barcelona @2GHz, @2.5GHz and Q6600@2.4Ghz, QX6850@3GHz. Both increasing the frequency by 25%. Only a few benchmarks were common between both. The gaming benchmarks for example were run at 1024*768 for Barcelona and 1600*1200 for C2Q so those can't be compared.

    Barcelona 2GHz to 2.5GHz:

    14.7% - Sysmark 2007
    23.4% - WME
    14.5% - iTunes
    21.2% - 3dsmax R9 SPECapc
    19.4% - Lightwave 3D


    Q6600@2.4GHz to QX6850@3GHz:

    15.2% - Sysmark 2007
    23.7% - WME
    21.5% - iTunes
    23.5% - 3dsmax R9 SPECapc
    21.3%/24.1% - Lightwave 3D - 2 different runs

    It should be noted that QX6850 runs at a higher FSB than Q6600 but this can't be helped. It's the best numbers I could find.

    Interesting strictly from a CPU scaling perspective. It's good to consider them all as an average lump, as some of that code is likely "Intellified", like Itunes.
    I was hoping to see a bigger advantage in scaling due to the AMD architecture, scaling doesn't appear like it is going to be "too much" better over Intel though.
  • flyck - Monday, September 10, 2007 - link

    you might want to consider that opteron had limited bandwith DDR2 667 for 4 cores which limits scaling and performance. For phenom we speak about DDR2 1024 without the registered latency.
