Thread: Nvidia geforce gtx 680

Three days before the official release of the first Geforce video card of the "next generation" further technical details and first benchmark results are known, consequently, this seems a rather dreary battle for the top of the league to announce graphics card, because the GTX 680, hot as the first model, could probably convince fully.


Have changed much is not really the core of the architecture, for example, writes PC-max.de , except for the further scaled down feature size of Kepler was of only 22nm compared to the previous "Fermi" done too little of the structure is by and large

remained the same. However, the newcomers have a least three times the amount of shader units, like its predecessor,GeForce GTX 580 On the 294mm ² silicon chip put under the engineer of NVidia 3.54 billion transistors with a frequency of approximately one GHz ( Turbo can be controlled = 1058MHz), whereas the internal video memory overclocked up to 3GHz.


The memory bus is sending you become smaller (256 instead of 384 bits), but not slower, which has to do with a doubling of the transferred texture units. Overall, the technique is therefore especially organized better, because with fewer parts in less space an improvement in performance was achieved. Most of the technical details but in fact only confirm what was already expected anyway.


The extent to which performance has improved, the boys from HKEPC (see video) trying to figure out where ever they had the pre-production for her. Depending on which Benchmark is being considered, results in almost all areas of a decent performance increase of between 10 and 30%. Especially in comparison to AMD current flagship, the Radeon HD 7970 NVidia has cut Kepler model well. In 3DMark11, the tests were able to detect up to 50% more performance in most tests, the core of Kepler at least somewhat better. In direct comparison, NVIDIA also performs better because of lower power consumption, because the 300 watts, the AMD card is less than the Kepler model whose power hungry with 195 watts specified is loose.
