While happy with my MSI GTX460 Cyclone SOC 1GB, any thoughts on the validity/performance in GPUGRID computing for this product: Another card which is likely to be available early next year is the GTX 560 which will replace the much successful GTx 460 GPU based on the GF-104 Core. The new GPU Core will be the GF-114 and will also be a refined version of the previous generation core. The GF-104 Core itself was a vast improvement over the GF-100 Core which resulted in much better performance while utilizing lower power and resulting in lower temps. Same would be with the new Core. All of the eight 48-core SMs will be enabled on the card which will provide 384 Cuda Cores as compared to the 336 of the GTX 460. I was considering adding a second GTX460 now, but this may be worth waiting for in improved performance. Thoughts? Pricing/market impact/purchase timing? | |

They are out now, although stock may be limited to start with. Pricing looks like arouund $210 (AUD). | |

I expect 1/3 of the shaders will not be usable, as with the GTX460. Ignoring any other changes and just going by frequency and shader count a GTX560 should be about 40% faster than a GTX460; (384/336)X(822/675)x100%=1.3917 | |

But until someone runs GPUgrid on it we'll never know for sure. The Palit card I referred to has the thing clocked higher (900Mhz) than a GTX570 reference design, that should make up a bit for lack of shaders. That and we're comparing a GF114 with a GF110, so its like comparing apples with oranges. Gigabyte also have a factory OC'ed GTX560 Ti SOC that is clocked at 1000Mhz, again with a dual fan cooling solution. Uses 195w at full load. ____________ BOINC blog | |

While I speculate on reference design performance to some extent, what we have known for some time is that the GTX560 has 384 cuda cores (shaders) but only 8 SMs, giving it a 48/1 ratio, the same ratio as the GTX460 (7 SMs), GTS450 (4 SMs) and numerous GT400 OEM cards (from 3 SMs down to 1); so the GTX560 is not like a GTX570 which has 15 SMs and a 32/1 ratio. The performance gulf between the cards is massive. | |

Hello: 266.66 driver is actually the 265 with arrangements to work with the new 560Ti not be if this could be the problem. Best regards. | |

Yes, the 266.66 is the only one for 560Ti, Einstein CUDA 3.2 task run, PG tpsieve CUDA 2.3 too (manual PSA). Other drivers did not find a GPU. | |
