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 GeForce GT 740M is 311 and by the Radeon HD 8670M is 311. 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 45 Watts to run but there is no entry for the Radeon HD 8670M.

GPU Mini Review

Mini ReviewRadeon 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 first revision of the Kepler Architecture.

The Kepler Architecture was NVIDIA's big step to power efficiency. Each Stream Multiprocessor (SMX) now hosts 192 Shader Processing Units - against the 48 of older Fermi Architecture, and has been redesigned being now clocked at the same speed of the Central Unit. This means they are more energy efficient and will consequently lead to cooler operating temperatures. However, it also means they are weaker. It can be said that one Fermi SMX is as fast as 2 Kepler SMXs.
Additionally, and not available in all GPUs, Kepler also introduced the Boost Clock Feature. The Boost Clock is an even higher Clock Speed activated when in gaming mode and becomes the effective speed of the GPU.

It equips a GPU Codenamed GK107-GT-740M which has 2 Stream Multiprocessors activated and thus offers 384 Shader Processing Units, 32 TMUs and 16 ROPs. The Central Unit is clocked at 810MHz.

The GPU accesses a 2GB frame buffer of DDR3, through a 128-bit memory interface. The size of the frame buffer is exaggerated and no way benefits the GPU. The Memory Clock Operates at 900MHz.

DirectX 11.0 Support (11.0 Hardware Default) and support for SLI, Kepler Boost, Optimus, CUDA, OpenCL, DirectCompute, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies

Power Consumption
With a rated board TDP of 45W, it is suited for average sized laptops.

GeForce GT 740M is essentially a fast GeForce GT 640M.
Gaming benchmarks indicate its Performance is around 3% worse than the older GeForce GT 650M.
