ECS P55H-AK: P55/NF200 Versus X58 In 3-Way SLI

We’ve seen how three-way SLI boosts gaming performance, but do we really need X58's PCI Express connectivity to realize those gains? Using three GTX 480s, we pit the latest P55/NF200 solution from ECS against a powerful X58-based incumbent to find out.

Benchmark Results: Alien Vs. Predator

Extreme details make Alien Vs. Predator one of the few games that can take advantage of multiple high-end graphics processors at medium resolutions. We already see the advantage of three-way SLI at our lowest test setting, and even more surprising is the P55+NF200 lead.

CPU bottlenecks become less of an issue as we push towards GPU limits. Just as surprising as the P55 win at middle resolutions is the X58’s win at high resolutions, since GPU “bottlenecks” should be far more restrictive than platform differences.

Possible reasons for the X58 platform’s win include its triple-channel memory controller, the slight latency increase caused by adding an NF200 bridge mid-stream on the P55 motherboard, or both.

    Well, if I'm shocked at anything, it's that the P55 platform actually outdid the x58 on some benchmarks. From a pure video card usage's perspective, you really won't be missing out on anything going for the P55 over the x58.

    And while this makes the P55 look good, what really sucks - if you're looking into the longevity of the P55 motherboards anyway - is that the new "Sandy Bridge" CPU's coming out in 2011 will feature a 1155 socket instead of an 1156, which means upgrading to a new motherboard.

    Very interesting reading, a bit shocked at the outcome. P55 can really be a viable alternative to X58 after all, even for the enthusiast crowd.

    Yes the 1156 platform is going bye bye it's realy sad.
    But i think that it shows that moving PCIa to CPU die is not a good idea as P55 with additional chip wins in the end - even the power usage test.

That is to say, you really don't need more than sixteen lanes from the CPU, for optimal SLI performance you only need those same 16 lanes to feed all graphics cards simultaneously.

    What an awesome board ECS has put together. I'd like to see a full review of this board - I'm intrigued with the effort ECS has put it to make what seems like a excellent piece of gear. Perhaps this will result in the trickle down effect if ECS is successful, that is, maybe starting at the high end will result in better mid- and low- range boards.

  • Nvidia does not seem to be bothered by continuing production of 65nm NF200. Would like to know if there is any R&D into a die-shrink to 40nm or less.

    tacoslaveyeah i hate how they took of one pin just to f@#$ with us.IIRC they didn't just take out one pin but they also redesigned how clocking of the CPU works. 1155 CPUs will have their own clock generator (as opposed to 1156's board-generated clock) and the board needs to support this. They could possibly hack-around this but why would they bother? Sheep will always buy the latest Intel stuff no matter what. :)

    This is an excellent article, nice analysis that I enjoyed reading before bed :).

    Now let all the trolls come out about the LGA 1155 release!
    Seriously, as a respective consumer to Intel, i have began to dislike their practices. Why do I not want SB? Hmmm...good question, same reason I do not want P55..short live and full of disaster!
