    What makes you think this will perform the same as a 280x?

    I base my k/h assumption that a mid end, although maxwell card, would not perform better than the top end kepler card.

    I went with 4x R9 270s last week because they only pull 138w each and give me 445KH/s.

    In the world of GPGPU, having access to a CPU through a very low-latency channel is a very appealing prospect. First off, this eliminates some of the normally required PCIe transfers, which are slow and costly. That's obviously always a good thing. CPU's are very good at general purpose computations. Unlike GPUs, CPUs are very good at making decisions. If you can offload a decent portion of the decision making to the CPU, that's a few percent of extra performance on *basic* GPGPU kernels while potentially much more on sophisticated kernels.

    About a month ago I restructured my finite-difference time-domain code by moving as many decision-making tasks (mostly if-statements) CPU-side as possible. In doing so I removed about 15 if-statements, but added 10-50 extra arithmetic operations per if-statement that I removed. The end result was a 4% performance increase, which given the simplicity of the kernels to begin with is pretty damn good. It will be interesting to see how the addition of the ARM on-board affects all of this.

    Translation: 20nm is so bad that TSMC told us to go F ourselves for production. We're desperately trying to get yields up, but every wafer super, extra, mega sucks. And we gotta paper launch a card (maxwell in general) really far ahead this time LOLZ.

    So 4% eh , add 10-20% and this poorly named card is not getting anywhere near a 7870 in compute never mind a 280x.
    It should however play games really well and with nvidias recent cross licence with intel they might have something brewing but then again intel did keep x86 off the licence so it may yet be tricky especially since intel seam to have access to nvidias patents and much more leverage in foundry tech then nvidia.
    This is panic status releasing by nvidia , , like I said ages ago maxwell (big proper one with 1tb bandwidth nested memory) is 2014 q4 earliest likely 1h 2015 on 20nm unless they have fully ditched tsv attached memory plans which would make for a lot of Bs in nvidias earlier pr slides

    The key to the 4% was just that it was gained by getting rid of a few if-statements. There are plenty of other operations that can be used in more sophisticated kernels that would gleam higher performance gains with offloading to a CPU.

    It will be interesting to see how much it actually helps with more complicated GPGPU kernels, but yeah I doubt it will approach anything like a 7870 or 280x in the vast majority of circumstances. Seems like more of a niche card.

    What settings did you use for that? My 7870 (with the same number of SPs) tops out at about 350 KH/sec.

    Funny how this thread went from maxwell to mining.
     
    HumanSmoke and xorbe say thanks.

    I would rather it be about maxwell as that is far more interesting.

    I've known about maxwell for quite a long while now and what it brings to the table. Anyone know what amd's R300 series cards are going to bring?

    So we'll have mining-induced GPU price inflation on top of nVidia's typical one? Nice! :p

    How do you mine inductance? Mining is so confusing. :(

    You know it's coming... Newegg is already inflating prices of AMD cards, and hoarding their most sought after cards, artificially restricting supply so they can create little gems like this beauty here:


    Mining Kit UKO-K140K: AMD Sempron 2.8GHz Single Core, 6 X Radeon R9 290X 4GB, 4GB RAM, 2 X 1500W 80 PLUS Gold Power Supply
    All this can be yours for only: $4,119.99!!

    It's only a matter of time before Nvidia steps into the ring, and then it's off to the races so to speak, dunno yet what part Maxwell will play in this game... :(

    I'm all for gaming and computing inspired innovation, and I really hope Nvidia is focusing on that with Maxwell, but the Pandora box has been opened, and fact is there's a big market in the mining business right now, and sooner than later we'll have two contenders in this arena.

    I'm looking forward particularly to what Maxwell will bring in terms of power
    efficiency, not very exited about the desktop parts, but mostly about the mobile parts!

    Those bastards, they did it ... save $250 LOL
    At least they could throw in 6 PCIE risers and a piece of a PC gamer's soul :cry:

    If true, that's a big gap from 750 Ti to 760 yeah?

    Is this looking like the other side of the tegra k1 binning tree to anyone else, ???.
    Like poor core bin but max gpu array bin
