Op-ed: The future will be measured in performance per watt

  1. Earlier this year Nvidia launched their GeForce GTX 750 Ti and GTX 750 graphics cards. Based on the latest Maxwell microarchitecture, the release garnered a surprising amount of attention. Normally cards in this price and performance bracket are unexciting workhorses; they're the...

  2. I have high hopes from Maxwell .

    True... until they find something else to make chip out of rather than silicon.

    So much about performance per watt - and where are the figures?

  5. An nvidia fanboy troll could have written a better article than this.

    "Nvidia’s Maxwell effectively doubled performance per watt against Kepler, and it thoroughly trounces AMD’s GCN architecture."

    Where is the data that shows Maxwell "trouncing" GCN?

    "Their GCN graphics core architecture is arguably more efficient than their VLIW4 and VLIW5 architectures of yesteryear,"

    Where is the data that shows GCN being "arguably" (instead of clearly) more efficient than VLIW?

    This article is written by a Technical Marketing Specialist of Corsair. Is this the official position of Corsair?

    Not just that but I dunno about you but I would love a GPU that can handle next-next-next-gen games on max seeing as the "Next-Gen" stuff isnt next get but last-last-last-Gen except Star Citizen that atleast looks to be a real Next-Gen game!

    Another interesting note, is that the cost of energy continues to increase much faster than inflation. In 15 years, it is easily possible that the cost of powering a laptop over a 3 year period will actually exceed the cost of the laptop itself - making power efficiency even more important.

    This article kinda reminds of the old American philosophy, "if you want more performance, you just add more cubes". That still holds true to a certain extent today but to quote Bob Dylan's famous song "the times they are a changing", and fast.
    No gamer or even enthusiast NEEDS a 1500W+ PSU unless they are just arrogant braggers. Hell, even the old Apollo spacecraft with it's enormous Saturn V booster required just 28 Amps to drive all it's electrical systems and that was 50 years ago.

    A rather tortured comparison I would have thought given that GPU efficiency and CPU efficiency aren't directly comparable given the disparate workloads.
    Interestingly enough, the only product line that both vendors have comparable products are math co-processors, and Nvidia's older Kepler architecture Tesla (235w K20X) stands up pretty well to Intel's current KNC Xeon Phi (300w SE10P). The current Green500 list, the general "go to" for GPGPU efficiency tends to support this view.
    On the net?
    It's not particularly difficult to find a perf/watt comparison. Many tech review sites now carry them. Here's a recent one from TPU for example - it only includes aggregated data from seventeen games, so YMMV

    That's because it's not an article. It's an op-ed.

    You mean, except for Maxwell things are pretty even? But wasn't Maxwell the architecture being addressed?
    As for Maxwell being 15% more efficient than the 265, the latest reviews say it's easily double that
