![]() PCIe 3.0 is now supported by the mobile Kepler series and GPU Boost 2.0 mode can automatically overclock the card if the laptop cooling system allows it. This feature is available on any notebook with a graphics card from the 800M series.Īccording to our benchmarks, the performance of the GeForce 825M is somewhere between the GT 730M and GT 740M. Furthermore, the GK208 chip has 16 TMUs and 8 ROPs on a 64-bit memory interface. GK208 is based on the Kepler architecture and offers two shader blocks, called SMX, each with 192 shaders for a total of 384 shader cores. The shaders are clocked at the same speed as the rest of the chip. It is based on the 28 nm Kepler architecture and uses the same GK208 chip as the GeForce GT 730M and 740M. The NVIDIA GeForce 825M (sometimes also called GT 825M) is a middle class DirectX 12 graphics card. NVIDIA GeForce 825M ► remove from comparison The 800M series also supports Optimus to automatically switch between an integrated graphics card and the Nvidia GPU. Therefore, the card is best suited for 14-inch laptops or larger. The power consumption of the GeForce 845M should be in a range of about 30 - 35 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. GM107/108 integrate the sixth generation of the PureVideo HD video engine (VP6), offering a better decoding performance for H.264 and MPEG-2 videos. Very demanding games such as Crysis 3 or Battlefield 4 will require lower resolutions and/or details. ![]() Many games of 2013/2014 (Tomb Raider or BioShock Infinite, etc.) can be played fluently in 1366 x 768 and high detail settings. However, a GeForce GTX 850M is still an additional 50 percent faster. Thanks to the 128-bit memory interface (respectively the GDDR5 memory of the GM108 model), the GeForce 845M offers about 30 percent more performance than the GeForce 840M. Similar to Fermi and Kepler, the GM107 and GM108 support DirectX 12 with feature level 11.0 only. The larger size can process some of the memory traffic to allow for a relatively narrow memory interface without significantly reducing 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.Īnother optimization is the massively enlarged L2 cache (GM107: 2 MB). ![]() Both models offer approximately the same performance.Ĭompared to Kepler, Maxwell has been optimized in several details to increase power efficiency. The NVIDIA GeForce 845M is a mid-range, DirectX 12-compatible graphics card for laptops unveiled in spring 2014. It is one of the first cards based on Nvidia's new Maxwell architecture, but is still manufactured in 28 nm. In addition to a version based on GM107 (partially deactivated to 384 ALUs, 128-bit, DDR3 memory), there is also another version using the GM108 chip (384 Shader, 64-bit, GDDR5 memory).
