In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 M275X are noticeably better than the Nvidia GeForce GT 750M 2GB GDDR5.

The GT 750M has a 41 MHz higher core clock speed than the Radeon R9 M275X, but the Radeon R9 M275X has 8 more Texture Mapping Units than the GT 750M. As a result, the Radeon R9 M275X exhibits a 5.9 GTexel/s better Texture Fill Rate than the GT 750M. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GT 750M has a 41 MHz higher core clock speed than the Radeon R9 M275X and the same number of Render Output Units. This results in the GT 750M providing 0.7 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 Radeon R9 M275X was released over a year more recently than the GT 750M, and so the Radeon R9 M275X is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GT 750M.

The Radeon R9 M275X and the GeForce GT 750M 2GB GDDR5 have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The memory bandwidth of the Radeon R9 M275X and the GeForce GT 750M 2GB GDDR5 are the same, which means the Radeon R9 M275X and the GT 750M have equal limitations when it comes to graphical data transfer.

The Radeon R9 M275X has 640 Shader Processing Units and the GeForce GT 750M 2GB GDDR5 has 384. However, the actual shader performance of the Radeon R9 M275X is 592 and the actual shader performance of the GT 750M is 406. The Radeon R9 M275X having 186 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon R9 M275X delivers a marginally smoother and more efficient experience when processing graphical data than the GT 750M.

The Radeon R9 M275X requires 50 Watts to run and the GeForce GT 750M 2GB GDDR5 requires 50 Watts. The two GPUs require the same amount of wattage to run. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

GPU Mini Review

Mini ReviewRadeon R9 M275X is a fast-middle-class-level graphics card based on the second revision of the Graphics Core Next architecture.
It offers a core codenamed Venus XTX that packs 640 Shader Processing Units, 40 TMUs and 16 ROPs, on a 128-bit memory interface of fast GDDR5. While the central unit runs at 900MHz and goes up to 925MHz, in Turbo Mode, the memory clock operates at 1000MHz. The regular version should offer 2GB of video memory but expect to see gimmicks of up to 4GB.
Its performance is practically identical to the old desktop Radeon HD 7770.
Overview
GeForce GT 750M v4 is a Fast-Middle-Class Mobile Graphics Card based on the first revision of the Kepler Architecture.

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.

GPU
It equips a GPU Codenamed GK107-N14P-GT which has 2 Stream Multiprocessors activated and thus offers 384 Shader Processing Units, 32 TMUs and 16 ROPs. The Central Unit is initially clocked at 941MHz and goes up to 1058MHz, in Turbo Mode.

Memory
The GPU accesses a 2GB frame buffer of fast GDDR5, 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 1000MHz.

Features
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 50W, it is suited for average sized laptops.

Performance
GeForce GT 750M v2 is essentially a fast GeForce GTX 660M.
Gaming benchmarks indicate its performance is only slightly below the desktop GeForce GTX 650.

System Suggestions
We recommend a decent processor (Intel Core i5 Mobile) and 8GB of RAM for a system with GeForce GT 750M v4.
