Rather it is intended for use in laptop/notebooks and will use the output of the host mobile device. This device has no display connectivity, as it is not designed to have monitors connected to it. The GPU is operating at a frequency of 1020 MHz, which can be boosted up to 1085 MHz, memory is running at 1253 MHz (5 Gbps effective).īeing a mxm module card, the NVIDIA GeForce GTX 860M does not require any additional power connector, its power draw is rated at 75 W maximum. NVIDIA has paired 4 GB GDDR5 memory with the GeForce GTX 860M, which are connected using a 128-bit memory interface. It features 640 shading units, 40 texture mapping units, and 16 ROPs. The GM107 graphics processor is an average sized chip with a die area of 148 mm² and 1,870 million transistors. Even though it supports DirectX 12, the feature level is only 11_0, which can be problematic with newer DirectX 12 titles. Built on the 28 nm process, and based on the GM107 graphics processor, in its N15P-GX-A1 variant, the chip supports DirectX 12. Manufacturerīattery Boost, GameStream, ShadowPlay, GPU Boost 2.The GeForce GTX 860M was a mobile graphics chip by NVIDIA, launched on January 13th, 2014.
#NVIDIA GEFORCE GTX 860M UPDATE WORSE SERIES#
The 800M series also supports Optimus to automatically switch between an integrated graphics card and the Nvidia GPU. Therefore, the 860M is best suited for 15-inch laptops or larger. The low-clocked Kepler version draws just slightly more power.
The power consumption of the GeForce GTX 860M should be similar to the old GTX 765M (about 60 watts). 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. However, very demanding games such as Crysis 3 or Battlefield 4 will require lower resolutions and/or details.ĭespite its considerably higher shader count, the Kepler version is about 10 percent slower, mainly due to the worse bandwidth efficiency.
Similar to Fermi and Kepler, Maxwell / GM107 supports DirectX 11.2 with feature level 11.0 only.Īlthough the GTX 860M has much less memory bandwidth and computing power, it can compete with (or sometimes even beat) the old Kepler-based GeForce GTX 770M while drawing significantly less power. Many games of 2013/2014 (Tomb Raider or BioShock Infinite, etc.) can be played fluently in FullHD resolution and very high detail settings. 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. 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.
