AMD Breaks 1GHz GPU Barrier With Radeon HD 4890

MojoKid writes "AMD announced today that they can lay claim to the world's first 1GHz graphics processor with their ATI Radeon HD 4890 GPU. There's been no formal announcement made about what partners will be selling the 1GHz variant, but AMD does note that Asus, Club 3D, Diamond Multimedia, Force3D, GECUBE, Gigabyte, HIS, MSI, Palit Multimedia, PowerColor, SAPPHIRE, XFX and others are all aligning to release higher performance cards." The new card, says AMD, delivers 1.6 TeraFLOPs of compute power.

    AMD Breaks 1GHz GPU Barrier

    I was diligently working at XYZ Corp a few buildings down when Incident One happened in their lab. At first, I was just sitting in my cubicle when suddenly we felt a severe shuddering of space & time around us. Then a few seconds later everyone heard a loud "Ka-BOOM" and everyone stood up to see what was going on outside. The buildings directly adjacent to the AMD lab had all their windows blown out and every car alarm within a square mile was going off. Some scientists with their hair blown straight back and carbon scoring randomly on their faces and white lab coats were seen to climb out of the rubble of AMD's R&D building. They immediately began dusting themselves off, high-fiving each other and patting each other on the back laughing and ecstatic. Then they headed towards the liqueur store down the street to pick up some champagne. Shortly after it was discovered that 1Ghz is the frequency at which æther vibrates when it is at rest so once you pass it, you leave a wake of æther behind your time cone. Roger Penrose and Stephen Hawking are due to give a speech at "GPU Ground Zero" this week, I hope to make it.

    If I were working marketing for AMD, I would be pointing out how switching from base ten to base eleven, twelve, thirteen, etc provides a theoretically unlimited amount of newsworthy advertisements in broken barriers. "We just need to make it to 2,357,947,691 hertz and we'll be the first to claim we've broken the 1 Ghz (base11) barrier! Where the hell was the report that we broke base9 last year?!"

      Not a bad idea, though discrete cards today have dedicated memory for the GPU, with a bus custom designed for that card. Not expandable, but high performance. The connection to main memory would be faster if the new socket was connected directly to the cpu socket, though that mostly helps UMA (i.e. cheap) solutions and having the GPU on die with the CPU would be cheaper. The extra cooling potential would be helpful for sure, either for performance or maybe to provide the same cooling quieter since my GPU is already my loudest fan!

      Pity some CPU maker couldn't come along, buy a GPU maker, and make something like this.

      Yeah, unless that company was also a motherboard maker, that might be a hard sell. An extra ZIF socket with heat sink mounts and extra memory channel, in mainstream desktop mobos? Yeah, foisting that kind of cost onto the mobo makers doesn't go over well unless you're the 800lb gorilla. Which of course isn't the company you're talking about.

      Something that I don't see other posters mention is that the design of many parts of the CPU are hand-tweaked down to the transistor level exactly for this purpose - low heat, high frequency. GPU's are designed in a larger scale, which is logical if you remember that if you exclude the cache, the CPU is a much simpler (in transistor count) than a GPU, when GPU generations occur much more often and differ more from one to the other. So, you have a fraction of the CPU design cycle to incorporate a radically different feature set, there is no time for the same kind of tweaks - if you end up with very low clock speeds you can still parallelize some more.
