The most interesting chips out of the bunch are the GeForce GTX 860M and the GeForce GTX 850M considering that these are the first mobile chips to feature the Maxwell core architecture. Maxwell Comes To Mobility As The GTX 860M and GTX 850M GPUs We again see no use of the extra VRAM unless the user is playing 2K games. The chip features a massive 6 GB GDDR5 memory which runs across a 192-bit bus at speeds of 5 GHz effective (1250 MHz QDR) pumping out 120.0 GB/s bandwidth. The GeForce GTX 870M features the GK104 core with 1344 CUDA cores, 112 TMUs, 24 ROPs, a clock speed of 941 MHz core and 967 MHz boost. Next up we have the GeForce GTX 870M which is another Kepler rebrand and a cut down version of the GeForce GTX 880M chip.
The memory runs along a 256-bit interface pumping out 160 GB/s bandwidth though we don’t know how the higher VRAM would benefit users in terms of raw performance numbers. The VRAM has been expanded to 8 GB GDDR5 and the clock speeds have been bumped to 933 MHz base and 954 MHz boost although the memory is clocked at 5 GHz effective rate. The GeForce GTX 880M is technically the same chip as the GeForce GTX 680M and GTX 780M with 1536 Cuda Cores, 128 TMUs and 32 ROPs but it has some key improvements. From the specifications, we can see that the GeForce GTX 880M would be the flagship chip of the mobility lineup but it's just a rebrand of the GTX 780M with some improved clock speeds.
Our buddies over at Videocardz managed to get hand of some exclusive slides which detail the performance and power efficiency of these new chips. From what we have seen, the GeForce GTX 880M and the GeForce GTX 870M are Kepler rebrands of the GeForce GTX 780M and GTX 770M chips while the GeForce GTX 860M and GTX 850M will feature the first generation Maxwell core architecture which made a debut last month with the GeForce GTX 750 series graphics cards. Apparently, the GeForce GTX 800M mobility lineup features both NVIDIA Kepler and Maxwell architecture based parts. Over the last few months, we have seen several leaks regarding the GeForce GTX 880M, GeForce GTX 870M and the most interesting GeForce GTX 860M GPUs. NVIDIA GeForce GTX 800M Mobility Chips Launching At CeBIT14
The NVIDIA GeForce GTX 800M Mobility chips will feature four new chips which include the GTX 880M, 870M, 860M and the 850M which will power the high-performance notebooks in 2014. NVIDIA is preparing to launch their next series of mobility chips codenamed the GeForce GTX 800M at CeBIT 2014.
