Wolfenstein

Finally among our benchmark suite we have Wolfenstein, the most recent game to be released using the id Software Tech 4 engine. All things considered it’s not a very graphically intensive game, but at this point it’s the most recent OpenGL title available. It’s more than likely the entire OpenGL landscape will be thrown upside-down once id releases Rage later this year.

Even at 2560 Wolfenstein is very close to being CPU limited when we’re working with SLI/CF. There’s just enough room for the 6990 to once again fall behind the 6950CF, however even the all-powerful 6970CF only eeks out a few more frames per second. In these conditions the test is less about the hardware and more about the software.

    My 470 still beats this at compute tasks. Hehehe.

    And damn, this card is noisy.

    Not even close, unless you are talking about outdated distributed computing projects like Folding@Home code. Try any of the modern DC projects like Collatz Conjecture, MilkyWay@home, etc. and a single HD4850 will smoke a GTX580. This is because Fermi cards are limited to 1/8th of their double-precision performance.

    In other words, an HD6990 which has 5,100 Gflops of single-precision performance will have 1,275 Glops double precision performance (since AMD allows for 1/4th of its SP). In comparison, the GTX470 has 1,089 Gflops of SP performance which only translates into 136 Gflops in DP. Therefore, a single HD6990 is 9.4x faster in modern computational GPGPU tasks.

    Those are just theoretical performance numbers. Not all programs *even newer ones* can effectively extract ILP from AMD's VLIW4 architecture. Those that can will no doubt with faster; others that can't would be slower. As far as I'm aware lots of programs still prefer nV's scalar arch but that might change with time. Reply

    Well.. if you can oly use 1 of 4 VLIW units in DP then you don't need any ILP. Just keep the threads in flight and it's almost like nVidias scalar architecture, just with everything else being different ;)

    It all depends on the driver and compiler implementation, and the guy/gal coding it. If you code the same but the compilers are generations apart, then the compiler with the higher generation wins out. If you've had more experience with CUDA based OpenCL, then your NVIDIA OpenCL implementation will outperform your ATI Stream implementation. Pick your card for it's purpose. My homebrew stuff works great on NVIDIA, but I only code for NVIDIA - same thing for big league compute directions. Reply

    ".....Cayman’s better power management, leading to a TDP of 37W"

    - is it honestly THAT good? :P

    oops...re-read...that was idle TDP !! Reply

    my old 7900gt used 48 at load

    Don't like the direction this is going. In GPUs it's hard to see any performance advances that don't come with equivalent increases in power usage, unlike what Core 2 was compared to Pentium4.

    Are you kidding? I have a 7900GTX I dont even use, because it fried my only spare large power supply. A 5670 is twice as fast and consumes next to nothing. Reply
