NVIDIA presents GeForce 800M series

NVIDIA has finally unveiled the long-awaited 8th generation of mobile graphics chips. Much to the surprise of analysts and fans the new chip family includes GPUs from three generations – Maxwell, Kepler and even Fermi.

As expected the GeForce GTX 880M/870M and 860M top the line but they are all based on the older Kepler architecture. It appears that NVIDIA still thinks that Kepler is more than enough for modern games and this is a fact that we can hardly deny. The GeForce GTX 880M comes with a GK104 GPU (Kepler) and has 1536 stream processors at 954 MHz and 4 GB of 256-bit GDDR5 memory at 5000 MHz. The GTX 870M offers the same GK104 core but it has 1344 stream processors at 941 MHz and 3 GB of 192-bit memory at 5000 MHz. The GTX 860M consists of two chips – the GK104 Kepler and the GM107 Maxwell. The Kepler processor has 1152 stream processors at 797 MHz and 2 GB of 128-bit memory at 5000 MHz, while the Maxwell core offers 640 stream processors at 1029 MHz. The memory is the same running at 5000 MHz.

The slower GTX 850M, 840M and 830M come with Maxwell cores. The GTX 850M is a GM107 Maxwell GPU with 640 stream processors at 936 MHz and 128-bit DDR3/GDDR5 memory at up to 5000 MHz (2 GB). The GTX 840M is a GM108 Maxwell GPU with 384 stream processors at 1029 MHz and 2 GB of 64-bit memory at 2000 MHz. There’s no information on the GTX 830M except that it is a GM108 Maxwell GPU with 2 GB of 64-bit memory. The GTX 820M is still a mystery as there’s no information on this one whatsoever.

The new NVIDIA chips promise between 15 per cent and 60 per cent better 3D performance. The 800M series is now available in notebooks made by Lenovo, MSI, Razer, Gigabyte and other companies.
