In just about every benchmark shown today and even in those not listed the multi-GPU results favor X58. Nothing shocking about that as in previous testing with both Nvidia and ATI video cards, we came to the same conclusion. The only difference today is that we are using the latest generation DX11 capable GPU and the percentage differences are not really any different with previous GPU chipsets. Where we did not have a difference was in actual game play experiences. It was impossible to tell the difference between platforms, except for some additional thermal output from the X58 setup.

If you happen to benchmark Intel platforms for a living, then clearly an X58/Bloomfield platform is the way to go. No questions asked, not even a hint of doubt should enter one’s mind as to the X58 being the logical choice. How about the other 99.9% of us? Well, if you just need that safe feeling that you are getting the maximum benefit out of those $380 HD 5870 cards you just purchased, the X58 paired with a Core i7 is an easy choice. It is an even easier choice if you plan on upgrading to Gulftown next year.

For those of us who are interested in power consumption, heat, noise, and not all that worried about a 2% to 7% difference in the benchmarks, then the Lynnfield platform is an attractive alternative with the latest generation GPUs. In fact, without the 920/X58 hanging around at similar pricing, the general thoughts/concerns regarding 860/P55 would probably be significantly different within the enthusiast community. The 860/P55 is a very good platform, especially for those running at stock or near stock speeds where the aggressive turbo mode will make a difference in daily computing tasks and your pocketbook.

That said, if you are running a single card such as the HD 5870, either platform is fine. However, performance in x8 mode was a bit disappointing for those needing the second slot for purposes other than graphics. In the end, performance in games was still very good and only a benchmark would inform you of less than stellar performance. What we cannot answer right now is if the dual x8 PCIe capability on Lynnfield will become a true bottleneck with the GPUs that follow the current/planned releases from AMD/Nvidia.

So our conclusion still has not changed from a month ago, if you plan on purchasing a high end multi-GPU setup you'll want to go with X58/Bloomfield for the best possible performance. If you want a great combination of application and gaming performance without the power consumption or heat concerns, the Lynnfield platform is a very attractive alternative.

    Wow, you're totally right:

    Lynnfield: 12-28 min FPS
    X58: 8-26 min FPS

    Talk about a crippled platform!

    We all already know that you're a moron, but in the future please try to make it less obvious. Thanks.

    The result of this test is really clear to me: if you are even remotely close to on a budget, P55 w/ a great card is the way to go. The $100 you save on a P55 mobo invested into graphics will get you way more than the same invested in X58 and a $100 cheaper graphics card. If money is no object, get X58. Perhaps more importantly, once we're dealing with cards and games that drop things well below the 60Hz refresh rate of our monitor, the additional bandwidth in X58 will probably make an even smaller difference.

    The fears regarding the integrated PCIe controller on Lynnfield are wildly exaggerated.

    I'd say a $100 difference in motherboards is largely an exaggeration depending on exactly what features you are looking for, the power consumption differences are far more interesting to me.

    Now if we could only find out whether 8x PCIe would be a bottleneck for a SATA3 card.
  • UNHchabo - Wednesday, September 30, 2009 - link

    In terms of theoretical bandwidth, there's plenty in a PCIe slot. The SATA 6Gbps standard gives about 600MB/s of effective bandwidth, and PCIe 2.0 has 500MB/s per lane. This means that with PCIe 2.0, your motherboard slot is only limiting your card's performance if you give one lane per port.

    Sure, and the power consumption savings are a nice plus. Then consider that 90+% of us don't even care about CF/SLI because we only ever one run GPU card, and there's really no reason to bother with X58 over P55.
  • ekoostik - Tuesday, September 29, 2009 - link

    Agreed. Really enjoyed reading this on my new single-GPU powered 860 sitting silently next to me.

    "Does that mean the integrated dual x8 PCIe 2.0 logic on Lynnfield is a poor choice compared to the dual x16 PCIe 2.0 sporting X58, absolutely not based on our initial tests."

    The comma after "X58" should be a question mark and "absolutely" should be the beginning of a new sentence. ;)

    almost 10% penalty because of the lynnfield crippled northbridge.
    its not just that but in the more interesting part of the game when there is more congestion, lynnfield stutters.
    if you are going to buy a new spanking 3.72 tflops directx ati card don't commit the mistake of using lynnfield.

    You're an idiot regardless of what you buy - so it evens out.

    "x58 is 1fps faster than lynnfield!!" as he sits behind his 33ms input lag, 3 frame ghosting, 60Hz LCD using a 600dpi mouse on a free mousepad.
