    Though Newegg is charging $580, the rumor of $550 turned out to be true. Goodbye Nvidia with your slower $650 GPUs (though they're issuing a price cut next month).

    No boost clock speed anymore. Now the stated clock speed of the GPU is the "up to" speed, and that speed will be maintained as long as temps don't exceed 95C. Yes, 95C. That is AMD's default max temp. On the plus side, the way the new settings work, the GPU will never run hotter than 95C unless you change the setting. This could be a good safety feature. If it tries to go above 95C, it throttles itself. Standard "up to" clock is 1000MHz.

    L2 cache on the 290X has been increased to 1MB, up from 768kB on the 7970.

    Length is 11", which is about 1/2" longer than a 780 or Titan.

    6-pin + 8-pin power connectors.

    Power usage....they claim TDP is 250W, however it's clearly closer to 300W. As i mentioned awhile back, it's obvious this GPU was meant to be made at a 20nm lithography, but AMD got in a hurry because of Nvidia being faster (at gaming) and TSMC was unable to pick up the pace, so AMD gets what they get.

    Re: AMD

    Crunching specs that matter to us

    GPU GFLOPS FP32 GFLOPS FP64 Price
    7970 3788.8 947.2 $300
    GTX 780 3977 165.7 $500
    7970GE 4096 1024 $310
    Titan 4494 1299 $1000
    GTX 780Ti 5046 210 $650
    Titan @ 1GHz 5376 1593 $1000
    R9 290X 5632 704 $550

    Update: FP64 on 290X may have been intentionally crippled to 1:8 SP instead of 1:4 standard. Though i have found only 1 source stating this, it's a very reliable one. Needs verification.

    Update 2: Verified

    No, that 165.7 on the 780 is not a typo. It just sucks that badly.

    Re: AMD

    So clearly the 7970GE (or any 7970 O/Ced over 1GHz) is the best credits / dollar ratio. Thanks, this thread helped me with the big decision.

    Re: AMD

    I have 3 7970s and 1 7950 running. (and 5870, 6950, 3 Nvidias )
    All cards are slightly overclocked and the first thing I do is resetting them to standard clocks with MSI Afterburner.
    The older ones tend to get hot rams after years of using so I decrease the Ram speed.
    They are 24/7 working and thats the best way to keep them alive.

    Ouch. AMD stock down 20% on news they have been downgraded to "underperform" by rating agency Canaccord Genuity. Yesterday AMD was trading at a two-year high... somehow I knew it wouldn't last!

    Re: AMD

    TSMC also lost 6% yesterday after shareholders found out Apple is switching back to Samsung for their lolphone processors. May drop more today because of it.
