Nvidia unveils GeForce GTX 650 and GTX 660
Nvidia today released two new GeForce graphics cards that work thanks to their 28-nm graphics chips sparingly and on top of Windows 8 interface DirectX 11.1 compatible. The GeForce GTX 660 will cost around 225 euros and is primarily intended for players. The Nvidia GeForce GTX 650 requires 115 euros - it is designed to compete with AMD's Radeon HD Series 7700th It contains much less functional units than the GeForce GTX 660, namely 384 instead 960th Also you GK107 graphics chip has no turbo mode, but remains dauerthaft in games at 1058 MHz.
The GeForce GTX 650 comes with 1 GB of GDDR5 memory connected via 128 data lines to the GPU (80 GB / s). They will burn maximum 64 watts, yet packs Nvidia standard is a 6-pin power connector on the motherboard. Overclockers will be pleased. In games, the GeForce GTX 650 should be 10 to 35 percent faster than AMD's Radeon HD 7750, according to Nvidia selected benchmarks. Check the lack of available test samples did not, however. Nvidia partners allowed until today the extradition.
With 980 MHz to run the 960 shader cores of the GTX 660th You may not, unless the TDP of 140 watts is not exceeded, on 1033 MHz or more dynamically overclock. GK106 between the GPU and the 2 GB memory (3004 MHz) are 192 data lines, the transfer rate is enough for full HD games (144 GB / s). SLI can be via the card also interconnect with one another.
In 3DMark 11, the GeForce GTX 660 manages around 6400 points in the performance setting. A GeForce GTX 670 is about 25 percent faster (8097 points). In very demanding Extreme mode, the GTX 660 reached around 2200 points. The power consumption is measured at idle 9 watts, the three-screen operation at 32 watts and in games at an average of around 110 watts. The GeForce GTX 650 is around 5 watts at idle and when playing HD videos swallow 13 watts - the Nvidia revealed during a conference call ..

Between the two graphics cards in terms of performance and price gapes still a big gap that will close in the second week of October, Nvidia, the GeForce GTX 650.
