Maxwell-Based GeForce GTX 800M Series To Be Revealed This Week... Nvidia is gearing up to launch its next series of mobile chips for laptop gaming, the GTX 800M series. Hot on the heels of Nvidia’s Maxwell debuts, the GeForce GTX 750 Ti and GTX 750, the GTX 800M series GPUs will be a mixture of both Kepler and Maxwell architecture. The four new chips are set to be the GTX 880M, 870M, 860M and the 850M, all of which will be targeted towards high-end performance gaming laptops… The Relative Importance Increase Of The New 800M Range Compared To Their Predecessors GeForce GTX 880M & 870M The GeForce GTX 880M and GTX 870M GPUs will, for the most part, be straight up refreshes of their previous-gen counterparts. They’ll be sporting the Kepler architecture and will be re-brands of the GTX 780M and 770M respectively, although some key changes should see some nice performance boosts. The core clock speed of the 880M sees a bump up to 933MHz from 823MHz, while the VRAM doubles up to a hefty 8GB GDDR5. Other than that it remains the same as the 780M before it, with 1536 CUDA cores on a 256-bit interface. The 770M meanwhile is another Kepler rebrand, this time clocked at 941MHz, with 6GB GDDR memory, across a 192-bit memory bus. Maxwell-based GTX 860M & 850M Where things get more interesting though are the GTX 860M and 850M. These are set to be the first mobile chips to take advantage of the Maxwell architecture. They are reportedly similar in design to the recently release GeForce GTX 750 Ti. The GeForce GTX 860M has 640 CUDA cores, 40 TMUs and 16 ROPs. It will also have 2GB of onboard GDDR5 memory, running on a slightly limiting 128-bit bus. No word on the exact clock speed yet, but we’d expect from the rest of its specs for it to weigh in at a very similar speed to the 750 Ti, so around 1GHz. The 850M will be very similar but will contain just 512 CUDA cores. While the specs are fairly modest, where this pair of cards is going to excel is in their efficiency. It’s something we’ve clearly seen from the GTX 750 Ti benchmarks and it looks to be the case here once again, owing to the Maxwell architecture. In terms of both power efficiency they are both streets ahead of their predecessors, with the 850M and 860M showing 60% and 40% improvements respectively. With the total power draw for both cards at 50w or less, this a pair of cards that should be fantastic for prolonged periods of gaming on the move. Some of the more powerful cards on the Kepler architecture have the potential to drain a laptop’s battery very quickly indeed, so this should improve things considerably. 800m-series-specs-table According to a series of leaked presentation slides the GTX 880M and 870M will be targeting 1080p gaming at Ultra settings, while the Maxwell-based 860M and 850M will be 1080p gaming on High settings. What do you make of these new cards? Why do you think Nvidia isn’t going wholly down the Maxwell for GPUs release in 2014? Let us know your thoughts!
