guru 3d fengu að prufa nýja kortið hjá nvidia ..
Guru 3D has got there hands on a GTX295 and ran a few benchmarks comaring it to the Mighty 4870X2, the word Mighty wont be used for much longer with the looks of things, testing was done with very early Beta drivers and an engineering sample of the card.
Now the GTX 295 is a bit of a weird combo. See, it has the memory volume and frequency of two GTX 260 cards yet the raw shader processor horsepower of two GeForce GTX 280 cards.
Memory: 1792 MB (896 MB per GPU)
Shaders processor: 240 per GPU, 480 in total
Core frequency: 576 MHz (Texture and ROP units)
Shader processor: 1242 MHz
So that makes it a bit of a hybrid in between two GTX 260 and 280 graphics cards. One thing is a fact though, it's an awful lot of computing power for sure.
Quick note for the true geeks: Each GPU features seven ROP and framebuffer partitions. Each ROP partition contains four ROP units, providing each GPU with 28 ROP units. Each framebuffer partition is connected to 128 MB of memory, totalling 896 MB of video memory for each GPU, thus times two. Total number of Texture Filtering Units: 160 (80x2).
Power consumption: while we cannot disclose any definitive numbers based on our own tests, you can rest assured that when these two GPU's are fully utilized the card can peak towards 289 watts power consumption. It remains to be discussed for the final review, but the GPU is now made on a smaller 55nm fabrication node which typically ensures lower voltages and thus power consumptions and TDP. In the end I can tell you though that power consumption will be slightly lower than the competition's X2.
