The GP104 chip is manufactured in 16nm FinFET process at TSMC and offers a range of new features. Therefore it is capable of WQHD and 4K gaming in high settings (see game benchmarks below). On average the GTX 1070 is around 20 percent faster than the old mobile GeForce GTX 980 and therefore the second fastest mobile graphics card (non SLI). In our benchmarks with various laptops the performance ranged from -5 to -14% slower performance compared to partner models of the GTX 1080 desktop models with slightly higher clocks. Nvidia claims that partner solutions can be up to 10 percent slower however. With a good fan system, the performance of the laptop version is on par with the desktop GTX 1070 (Founders Edition). The performance depends on the cooling solution of the laptop. Sadly this variant im sold with the same GTX 1070 name, making it hard to judge the performance. The TDP is also reduced and rumored to be 10 Watts higher than the predecessor, the GTX 980M.įor thin and light laptops Nvidia offer a Max-Q called version of the GTX 1070 with lower TDP and also significantly lower performance. Instead of the new GDDR5X, the GTX 1070 uses slower GDDR5 graphics memory - but still 8 GB. Both cards are based on a cut down GP104 chip (like the GTX 1080) and are manufactured in 16 nm FinFET at TSMC.Ĭompared to the GTX1080, the GTX1070 features less CUDA cores (2048 versus 2560) that are clocked a bit lower (maximum Boost 1645 versus 1733). It comes in two variants, the desktop version (see here for the detail page) with 1920 shaders and the mobile variant with 2048 shaders and lower clock rates. The Nvidia GeForce GTX 1070 is the second fastest Pascal based graphics card in mid May 2016.

The power consumption of the GeForce GTX 860M SLI should double from 60 to about 120 watts (including board and memory) compared to a single GTX 860M. Of course, VP6 supports all features of previous generations (4K support, PIP, video encoding via NVENC API). Unfortunately, HDMI 2.0 is still not supported. GM107 integrates the sixth generation of the PureVideo HD video engine (VP6), offering a better decoding performance for H.264 and MPEG-2 videos. Most games (as of 2014) are playable at the highest detail setting and in FullHD resolution. In many cases it is even possible to activate additional anti-aliasing. Accordingly, the 860M SLI competes with the high-end single-GPU GeForce GTX 880M. The GeForce GTX 860M SLI is about 70 - 80 percent faster than a single GTX 860M, leading to a performance somewhere between a single GeForce GTX 680 (desktop) and Radeon R9 280X (desktop). Similar to Fermi and Kepler, Maxwell / GM107 supports DirectX 12 with feature level 11.0 only. The increased size can handle some of the memory traffic to allow for a relatively narrow memory interface without significantly reducing the performance. Each of the two GM107 features 5 SMMs and thus 640 shader cores, 40 TMUs and 16 ROPs (128-bit interface).Īnother optimization is the massively enlarged L2 cache (GM107: 2 MB). Smaller Streaming Multiprocessors (SMM) with only 128 ALUs (Kepler: 192) and an optimized scheduler should lead to better utilization of the shaders. Nvidia promises that a Maxwell SMM with 128 ALUs can offer 90 percent of the performance of a Kepler SMX with 192 ALUs. This happens because of different timespans between two frames (e.g., irregular delays between sequential frames).Īlternatively, there is also a version based on the Kepler chip GK104, which has 1152 shader units clocked at 797 MHz.Ĭompared to Kepler, Maxwell has been optimized in several details to increase power efficiency. Therefore, it may suffer from micro stuttering in low fps ranges of 30fps. The clocks for the SLI-setup are identical to a single GTX 860M. With SLI, each card usually renders a single frame (AFR mode). Each card has a 28 nm GM107 core based on the Maxwell architecture. The NVIDIA GeForce GTX 860M SLI is a high-end DirectX 12-compatible graphics solution for laptops, consisting of two GeForce GTX 860M. NVIDIA GeForce GTX 860M SLI ► remove from comparison
