In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 8870M are significantly better than the Nvidia GeForce GT 740M.
The GeForce GT 740M has a 85 MHz higher core clock speed than the Radeon HD 8870M, but the Radeon HD 8870M has 8 more Texture Mapping Units than the GeForce GT 740M. As a result, the Radeon HD 8870M exhibits a 3.1 GTexel/s better Texture Fill Rate than the GeForce GT 740M. 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 85 MHz higher core clock speed than the Radeon HD 8870M and the same number of Render Output Units. This results in the GeForce GT 740M providing 1.4 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.
Both the Radeon HD 8870M and the GeForce GT 740M were released at the same time, so are likely to be quite similar.
The Radeon HD 8870M and the GeForce GT 740M have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.
The Radeon HD 8870M has 43.2 GB/sec greater memory bandwidth than the GeForce GT 740M, which means that the memory performance of the Radeon HD 8870M is noticeably better than the GeForce GT 740M.
The Radeon HD 8870M has 640 Shader Processing Units and the GeForce GT 740M has 384. However, the actual shader performance of the Radeon HD 8870M is 496 and the actual shader performance of the GeForce GT 740M is 311. The Radeon HD 8870M having 185 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon HD 8870M delivers a significantly smoother and more efficient experience when processing graphical data than the GeForce GT 740M.
The Radeon HD 8870M requires 50 Watts to run and the GeForce GT 740M requires 45 Watts. The Radeon HD 8870M requires 5 Watts more than the GeForce GT 740M to run. The difference is not significant enough for the Radeon HD 8870M to have a noticeably larger impact on your yearly electricity bills than the GeForce GT 740M.

|Mini Review||Overview |
Radeon HD 8870M is a Performance Mobile Graphics Card based on the Second Revision of the GCN Architecture.
The GCN 1.1 Release adds support for AMD's TrueAudio Technology which does calculations of audio effects "better" than the CPU and further improves the Powertune Technology.
It equips a GPU codenamed Venus XT which has 10 Compute Units activated and thus offers 640 Shader Processing Units, 40 TMUs and 16 ROPs. The Central Unit Initially Operates at 725MHz and goes up to 775MHz, in Turbo Mode.
The GPU accesses a 2GB frame buffer of fast GDDR5, through a 128-bit memory interface. The size of the frame buffer is adequate. The memory clock operates at 1125MHz.
DirectX 11.0 Support (11.0 Hardware Default) and support for Crossfire, PowerTune Technology, Eyefinity, App Acceleration, HD3D, ZeroCore Power and other technologies.
With a rated board TDP of 50W, it is suited for 17" or larger laptops.
Gaming benchmarks put its performance on average with NVIDIA's GeForce GTX 670M.
We recommend a Decent Processor (Intel Core i5 Mobile) and 8GB of RAM for a system with Radeon HD 8870M.
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
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.
We recommend a decent processor (Intel Core i5 Mobile) and 8GB of RAM for a system with GeForce GT 740M.
