NVIDIA GeForce 825M vs NVIDIA GeForce 845M
NVIDIA GeForce 825M
► remove from comparison The NVIDIA GeForce 825M (sometimes also called GT 825M) is a middle class DirectX 12 graphics card. It is based on the 28 nm Kepler architecture and uses the same GK208 chip as the GeForce GT 730M and 740M.
Architecture
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. Furthermore, the GK208 chip has 16 TMUs and 8 ROPs on a 64-bit memory interface.
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.
Performance
According to our benchmarks, the performance of the GeForce 825M is somewhere between the GT 730M and GT 740M. Current games (as of 2013/2014) can thus be played in 1366 x 768 and medium settings. However, very demanding games such as Crysis 3 or Battlefield 4 will require lower resolutions and/or details.
Features
The feature set of the 825M corresponds to the GT 730M and 740M. This includes support for up to 4 active displays. Furthermore, high resolution monitors of up to 3840x2160 pixels can now be connected using DisplayPort 1.2 or HDMI 1.4a if available. HD-Audio codecs, such as Dolby TrueHD and DTS-HD, can be transmitted via bitstream mode through the HDMI port. However, as most laptops will feature Optimus, the integrated GPU will likely have direct control over the display ports and may limit the feature set available by the Nvidia Kepler cards.
The 5th generation PureVideo HD video processor (VP5) offers hardware decoding of HD videos. Common codecs such as MPEG-1/2, MPEG-4 ASP, H.264 and VC1/WMV9 are fully supported up to 4K resolutions while VC1 and MPEG-4 are supported up to 1080p. Two streams can be decoded in parallel for features such as Picture-in-Picture. Another feature is the inclusion of a dedicated video encoding engine similar to Intel QuickSync that can be accessed via the NVENCI API.
Power Consumption
The power consumption of the GeForce 825M should be similar to the GT 730M. As a result, the Nvidia GPU is best suited for multimedia notebooks 14-inches in size or greater. The 800M series also supports Optimus to automatically switch between an integrated graphics card and the Nvidia GPU.
NVIDIA GeForce 845M
► remove from comparison 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). Both models offer approximately the same performance.
Architecture
Compared to Kepler, Maxwell has been optimized in several details to increase power efficiency. 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.
Another optimization is the massively enlarged L2 cache (GM107: 2 MB). The larger size can process some of the memory traffic to allow for a relatively narrow memory interface without significantly reducing performance.
Similar to Fermi and Kepler, the GM107 and GM108 support DirectX 12 with feature level 11.0 only.
Performance
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. However, a GeForce GTX 850M is still an additional 50 percent faster. Many games of 2013/2014 (Tomb Raider or BioShock Infinite, etc.) can be played fluently in 1366 x 768 and high detail settings. Very demanding games such as Crysis 3 or Battlefield 4 will require lower resolutions and/or details.
Features
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. 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.
Power Consumption
The power consumption of the GeForce 845M should be in a range of about 30 - 35 Watts. Therefore, the card is best suited for 14-inch laptops or larger. The 800M series also supports Optimus to automatically switch between an integrated graphics card and the Nvidia GPU.
