Gaming Performance Comparison
In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 740M are significantly better than the AMD Radeon HD 8670M.
The GeForce GT 740M has a 35 MHz higher core clock speed and 8 more Texture Mapping Units than the Radeon HD 8670M. This results in the GeForce GT 740M providing 7.3 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.
The GeForce GT 740M has a 35 MHz higher core clock speed and 8 more Render Output Units than the Radeon HD 8670M. This results in the GeForce GT 740M providing 6.8 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.
The GeForce GT 740M was released less than a year after the Radeon HD 8670M, and so they are likely to have similar driver support for optimizing performance when running the latest games.
The GeForce GT 740M has 1024 MB more video memory than the Radeon HD 8670M, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GeForce GT 740M also has superior memory performance overall.
The GeForce GT 740M has 14.4 GB/sec greater memory bandwidth than the Radeon HD 8670M, which means that the memory performance of the GeForce GT 740M is slightly better than the Radeon HD 8670M.
Both the Radeon HD 8670M and the GeForce GT 740M have 384 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the . Knowing that the shader performance of the GeForce GT 740M is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.
The GeForce GT 740M requires 33 Watts to run but there is no entry for the Radeon HD 8670M.

|Mini Review||Radeon HD 8670M is a middle-class Graphics Card based on the GCN architecture. |
It features the Mars XT GPU and thus offers 384 Shader Processing Units, 24 TMUs and 8 ROPs. The central unit can be initially clocked at up to 775MHz reach up to 825MHz in Turbo Mode while the memory interface is of 64-bit of standard DDR3.
It can be addressed as a fast Radeon HD 8550M due to its considerably higher core-clock speed.
Benchmarks indicate its performance is somewhat above NVIDIA's GeForce GT 630M and thus the card can run most modern games at medium games.
|GeForce GT 740M is a middle-class mobile graphics card based on the 28nm, Kepler architecture. |
It's based on the Kepler GK107 Core and offers 384 Shader Processing Units, 32 TMUs and 16 ROPs, on a 128-bit memory interface of DDR3. The central unit runs at 810MHz (890MHz in Turbo Mode) and the memory clock operates at up to 900MHz.
Its performance is therefore similar (though slower) to the DDR3 Variant of previous GeForce GT 650M and so most modern games will run at medium or high settings. Its power consumption should be lower, thanks to the power optimizations.
This Graphics Card needs to be paired with an average Quad Core CPU and can only achieve fluent frame rates at 1366x768.
