Guru of 3D posted their review of the GTX680 today: Maybe this will work... Fixed the link, nothing like copy and paste. My Amazon Wishlist / TV |

The comments didn't speak too highly of the 480's. Heck, with some water cooling, and a huge overclock, they can hold their own.....:D Steve Warning, addicted to SETI crunching! Crunching as a member of GPU Users Group. GPUUG Website |

I have been waiting for the 79xx price`s to fall after nvidia`s 6xx came out, As it says in the article they have taken their time about it, They have to cash in on it if sale`s are good. |

The AMD Radeon HD7990will be released to the wild on 17th April @ $849 Expensive ... I wonder if there are takers? It's good to be back amongst friends and colleagues ![]() ![]() |

The current high prices & lack of availability for the latest GPUs can be blamed on TSMC and their problems producing 28nm wafers. And because production & supply is so limited for the new GPUs, the older ones continue to remain (relatively) expensive. Don't expect things to improve until late this year. 3rd Quater at best.

AnandTech - The Intel Ivy Bridge (Core i7 3770K) Review 22 pages and I couldn't find a single AVX reference for you guys:( But I did find this on page 19: " ... Ivy Bridge is the first true compute capable GPU from Intel. This marks an interesting step in the evolution of Intel's GPUs, as originally projects such as Larrabee Prime were supposed to help Intel bring together CPU and GPU computing by creating an x86 based GPU. With Larrabee Prime canceled however, that task falls to the latest rendition of Intel's GPU architecture. With Ivy Bridge Intel will be supporting both DirectCompute 5—which is dictated by DX11—but also the more general compute focused OpenCL 1.1. Intel has backed OpenCL development for some time and currently offers an OpenCL 1.1 runtime for their CPUs, however an OpenCL runtime for Ivy Bridge will not be available at launch. As a result Ivy Bridge is limited to DirectCompute for the time being, which limits just what kind of compute performance testing we can do with Ivy Bridge."

AnandTech - The Intel Ivy Bridge (Core i7 3770K) Review That's to bad. I would have thought they would have gone a bit further to support OpenCL. Larrabee was pulled, but it lives on in the Knight's whatever series. That's when things will get more interesting. That's head to head with NVidia in gpgpu computing. They better have their OpenCL act together by then. The GPU on IvyBridge, while interesting, doesn't compete with the massive independent coprocessor units of NVidia and ATI. That may change though. Getting the data to where it gets crunched is the real bottleneck. |

Getting the data to where it gets crunched is the real bottleneck. PCIe 3 is now here. I wouldn't consider 984MB/s a bottleneck. If it is a x16 link gives almost 15.8GB/s. Grant Darwin NT |

It's 2 680s on the same board with some nice features, but bare in mind with it being 680s their DP performance is going to be the same as erm a 680. |

Release date today for the 690, price wise = dedicated cruncher for sure! Anyone care to guess at the numbers in terms of output? It kind of appeals to kick out one card that will beat (and some) my entire old diskless seti farm from back in the day :) https://www.aria.co.uk/Products/Components/Graphics+Cards+-+NVIDIA/GeForce+GTX+690 3072 cuda cores is just insane, that's pretty much got to be getting close to the realms of the CPU not being able to feed it - or saturating one of the transports? I dunno, but I'm excited about the card despite the cash outlet I am seriously considering a dedicated 24/7 cruncher in the datacentre rack - just got to hope I have enough headroom in AMPs by turning off the current machines.

just got to hope I have enough headroom in AMPs by turning off the current machines. The new GPUs are very low power users compared to what went before. A GTX690 under full load draws less power than a single GTX580 card under the same load. A single GTX690 actually draws less power than 2 GTX680s- about 85W less. Grant Darwin NT |

Thereby saving the planet. Don't I wish. "The secret o' life is enjoying the passage of time." 1977, James Taylor "With cats." 2018, kittyman ![]() |

just got to hope I have enough headroom in AMPs by turning off the current machines. current machines in there are a little old now, might be time for an end of tax year refresh If I can pull more points, less leccy usage in the 1/4 rack all the better. Just me, or does there seem to be very little point in CPU crunching now? Not a single GPU is in the rack, all the GPU power is in offices under desks heating the rooms! ![]() |

... Unfortunately you still need a CPU, and might as well get more use out of it than simply feeding the GPU. And doing CPU crunching using mature technologies and compilers provides a very good level of quality control. My estimate is that more than 60% of the work is being done on CPU still, and they are far more reliable than GPUs overall. But certainly anyone building a system intended mainly for crunching ought to concentrate on the GPU capability. With the GPUUG efforts and probable future improved download it may even become sensible again to aim at the most crunching capability which can be achieved in a single system, for now two or three lesser systems are more likely to be able to maintain full productivity.
