The NVIDIA GeForce GTX 670MX SLI is a high-end DirectX 11-compatible laptop graphics card made up of two GeForce GTX 670MX. Each card is equipped with a 28nm GK104 core based on the Kepler architecture.
Each SLI card typically renders a single frame (AFR mode). As a result, micro stuttering may occur in low fps ranges of 30fps. This is due to the different timespans between the two frames (e.g., irregular delays between sequential frames).
Brief Description Of Nvidia Geforce GTX 670mx
Let us discuss the features of this card:
1. Architecture
The general architecture of the card:
- The Kepler architecture replaces the Fermi architecture, which debuted in laptops with the GeForce 400M series. The GK106 Kepler core includes five shader blocks known as SMX that run at the same speed as the central core.
- All five blocks in the GTX 670MX are active, resulting in 960 CUDA cores.
- Although the Kepler architecture has more shader cores than the Fermi design, the Kepler shaders are expected to be up to twice as power efficient.
- However, because the shader domain lacks a hot clock, two shaders on a Kepler chip have the same speed as one shader on a Fermi chip (as the latter is clocked twice as fast).
- The mobile Kepler series now supports PCIe 3.0, and an optional Turbo mode can automatically overclock the Nvidia card by a theoretical 15% if the laptop cooling system allows it.
- This boost mode is implemented in the BIOS, but it is ultimately determined by the laptop’s manufacturer.
2. Performance
Performance of this card:
- The graphics performance of the GeForce GTX 670MX SLI is dependent on the benchmark/game’s driver support.
- It can be up to twice as fast as a single GTX 670MX in ideal conditions, making it one of the fastest mobile graphics solutions for laptops in 2012.
- The performance should be comparable to a single GTX 680M on average, but with the issues of micro stuttering (see above) and higher power consumption.
- The GPUs are powerful enough to run 2012 games smoothly with Full HD resolution, maxed-out graphical settings, and antialiasing.
- Even the most demanding games, such as Metro 2033, Alan Wake, and Risen 2, can be played at the highest detail settings.
3. Features
Features of this graphics card:
- The enhanced feature set now supports up to four active displays. In addition, high-resolution monitors with resolutions of up to 3840×2160 pixels can now be connected via DisplayPort 1.2 or HDMI 1.4a, if available.
- HD-Audio codecs such as Dolby TrueHD and DTS-HD can be transmitted through the HDMI port in bitstream mode.
- However, because most laptops will include Optimus, the integrated GPU will almost certainly have direct control over the display ports, potentially limiting the feature set available from Nvidia Kepler cards.
- The GK104 core also houses the 5th generation PureVideo HD video processor (VP5), which provides hardware decoding of HD videos.
- MPEG-1/2, MPEG-4 ASP, H.264, and VC1/WMV9 are all fully supported up to 4K resolutions, while VC1 and MPEG-4 are only supported up to 1080p.
- For features like Picture-in-Picture, two streams can be decoded in parallel. Another unique feature is the inclusion of a dedicated video encoding engine, similar to Intel QuickSync, which can be accessed via the NVENC API.
4. Power Consumption
Power consumption information:
- When compared to a single GTX 670MX, the power consumption of the GeForce GTX 670MX SLI should be doubled.
- As a result, only large desktop replacements can withstand the heat.

Conclusion
This is a top-class graphics card if you like to play games from around 2012-13. Of course, since it’s very old, it does not make sense to try and run newer games on it. If you have this card, then that means you own an older system too. So that was our opinion on this graphic card. Let us know your thoughts in the comments below.
