Leaked roadmap forecasts 28-nm Fermi shrinks for 2012

We already know that Kepler, Nvidia’s next-gen 28-nm GPU, isn’t scheduled to enter production until next year. Well, the folks at SemiAccurate have now gotten some dirt on a batch of other 28-nm parts Nvidia has in the pipeline. Those products are said to be shrinks of existing Fermi GPUs, and their production schedules purportedly suggest Kepler won’t hit stores until March 2012 at the earliest.

SemiAccurate shows a list of 10 upcoming 28-nm mobile parts with power envelopes as low as 15-20W and as high as 70-75W. Memory interfaces will range from 64 to 256 bits in width, and they’ll be connected to as much as 2GB of GDDR5 RAM on higher-end offerings. Other details are slim; the site says some information is "a bit blurred to protect the exact sub-species of mole involved," so I assume that’s intentional.

The most interesting nuggets of information are perhaps the sampling and mass production time frames. Seven of these Nvidia GPUs will start sampling in early October, and those same parts are due to be mass produced in late December. SemiAccurate predicts that Nvidia’s Kepler offerings "will trail the above by at least three months, likely more." You do the math.

We’d recommend taking that information with a grain of salt, of course. That said, if SemiAccurate is right, then Nvidia won’t have any 28-nm GPUs out this year. AMD, meanwhile, has gone on record to say it will "deliver" 28-nm products this year. We’ll just have to see how all of these predictions pan out.

    So are the updates to the Fermi chips going to be all mobile or some desktop variants as well? I didn’t derive much from SemiAccurate-not sure I ever do.

    And a March release? Out. Glad I pulled the trigger on a released card, not sure I could wait with shiny new games like BF3 coming out.

      I think Charlie said the purpose of this was cost-cutting on the OEM side, not raising performance, so it’s only mobile and even if it was desktop don’t expect retail cards for a while.

      When I saw the actual next gen will be Q2 or later I was also glad I bought recently.

        Ditto. What did you purchase?

    >=15W for a mobile chip? Isn’t that a tad high?

      Not even remotely. It’s not a “chip.” It’s a ton of chips on a PCB. Think about everything that has to be there even on the lowest end graphics cards.

        Yes, but are these low-end solution any better than what’s integrated into CPUs these days (Llano, etc)? Because the specs for the GT520 and 63×0/64×0 don’t really look 15W worth of better to me…

    I really don’t care how many nanometers wide the circuit traces in my GPU are; I care about performance within reasonable power requirements. Fermi always delivered great power; it was it’s horrendous appetite for electricity that put me off it. If this process shrink solves that (as it seems it would), then it just comes down to raw performance vis-a-vis new AMD parts.

      Nvidia’s drivers function better with workstation apps like solid works and adobe CS. I love AMD consumer cards for gaming but they can’t compete with the flexibility of Nvidias driver set.

          Those HD5870s are STILL freezing/crashing on my friend’s PC, and he’s updated the driver every single time a new one comes out in hopes getting rid of that issue… just to be disappointed again and again.

          When will AMD learn to write decent graphics drivers?

            If your friend can’t get a 5870 to work, chances are something else is wrong or the card is defective. AMD drivers have their issues, yes, but they aren’t so bad that they constantly freeze/crash machines. I’ve seen ONE real bug that was noticeable, that was the ‘cursor lag’ at the top right of the screen.

            It has been fixed in 11.6 and 11.7.

            They may have some other odd issues, but nothing so critical that it crashes/freezes. I’d check the power supply or replace the card. There’s more to that problem than drivers.
