NVIDIA GeForce GT 640 tested
As usual in recent times, the vast majority of rumors end up being successful. Last week leaked specifications of the new GPUs Nvidia GeForce GT 640 in its three editions , rumor materialized ends today, though with a slight error.
The three editions of the Nvidia geforce GT 640 GPU
Nvidia has three variants of its new gpu Geforce GT 640, 2 of which are based on the core gk107 (Kepler) differing by having DDR3 and GDDR5 128-bit bus, and a third version, which is actually a Geforce GT 545 renowned old kernel-based GPU GF116 (Fermi).
Here the specifications of the three variants of the GeForce GT 640:
It is noted that unlike her older sisters (GeForce GTX 670/680/690) the GT 640 GPU lacks the Boost technology, we assume that the decision was motivated by keeping the chip within the ranges reported TDP of 65W.
Without further ado here are some of the tests performed by Expreview the Galaxy GeForce GT 640, which comes factory overclocked to 1006MHz and is the model based on DDR3 memory GK107:
We see that despite having a 26.22% overclock, the GPU Geforce GT 640 (U.S. $ 109 for DDR3 version and $ 129 for GDDR5 version) is far from reaching the GPU AMD Radeon HD 7750 (U.S. $ 109) The lower performance GPU architecture-based Core Graphics Next (GCN) of AMD, which does not leave a very good feeling about this new proposal from Nvidia, unless reduction in its suggested price.
