The increased size can handle some of the memory traffic to allow for a relatively narrow memory interface without significantly reducing the performance. 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. 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). The GTX 860M offers 640 shader units clocked at 1029 MHz (+ Boost) as well as 4 GB of GDDR5 memory (128 bit, 5000 MHz effective).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. OptimusĪPIs supported by GeForce GTX 860M SLI, sometimes including their particular versions.The NVIDIA GeForce GTX 860M is an upper mid-range, DirectX 12-compatible graphics card for laptops unveiled in March 2014. It is one of the first cards based on Nvidia's new Maxwell architecture (GM107 chip), but is still manufactured in 28 nm.
You'll probably need this information if you need some particular technology for your purposes. Technological solutions and APIs supported by GeForce GTX 860M SLI. Note that GPUs integrated into processors have no dedicated memory and use a shared part of system RAM instead. Parameters of memory installed on GeForce GTX 860M SLI: its type, size, bus, clock and resulting bandwidth. For notebook video cards it's notebook size, connection slot and bus, if the video card is inserted into a slot instead of being soldered to the notebook motherboard. Useful when choosing a future computer configuration or upgrading an existing one. Information on GeForce GTX 860M SLI's compatibility with other computer components. These parameters indirectly speak of GeForce GTX 860M SLI's performance, but for precise assessment you have to consider its benchmark and gaming test results. GeForce GTX 860M SLI's general performance parameters such as number of shaders, GPU base clock, manufacturing process, texturing and calculation speed.
