In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7750M are significantly better than the Intel HD Graphics 4600 Mobile.

The Radeon HD 7750M has a 175 MHz higher core clock speed and 28 more Texture Mapping Units than the Graphics 4600. This results in the Radeon HD 7750M providing 16.8 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 Radeon HD 7750M has a 175 MHz higher core clock speed and 14 more Render Output Units than the Graphics 4600. This results in the Radeon HD 7750M providing 8.4 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The Graphics 4600 was released over a year more recently than the Radeon HD 7750M, and so the Graphics 4600 is likely to have better driver support, meaning it will be more optimized for running the latest games.

The Radeon HD 7750M has 1024 MB video memory, but the Graphics 4600 does not have an entry, so the two GPUs cannot be reliably compared in this area.

The HD Graphics 4600 Mobile has 80 Shader Processing Units and the Radeon HD 7750M has 512. However, the actual shader performance of the Graphics 4600 is 157 and the actual shader performance of the Radeon HD 7750M is 250. The Radeon HD 7750M having 93 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon HD 7750M delivers a significantly smoother and more efficient experience when processing graphical data than the Graphics 4600.

The Graphics 4600 transistor size technology is 6 nm (nanometers) smaller than the Radeon HD 7750M. This means that the Graphics 4600 is expected to run very slightly cooler and achieve higher clock frequencies than the Radeon HD 7750M.

The HD Graphics 4600 Mobile requires 45 Watts to run and the Radeon HD 7750M requires 28 Watts. The Graphics 4600 requires 17 Watts more than the Radeon HD 7750M to run. The difference is not significant enough for the Graphics 4600 to have a noticeably larger impact on your yearly electricity bills than the Radeon HD 7750M.

GPU Mini Review

Mini ReviewIntel HD Graphics 4600 Mobile is the successor to Intel HD 4000 Mobile that's featured in the Haswell based Mobile CPUs.
It features 20 Execution Units (80 Shader Processing Units) and its central-unit speed will range between 400MHz and 1300MHz (Turbo Boost) and that the fastest memory supported is DDR3-1600 meaning its memory-clock will operate at 800MHz, at the most.
Benchmarks indicate its performance is up to 25% better than previous Intel HD 4000. However, only Iris Graphics offer performance good enough to play all modern demanding games, some even with extremely fluent frame rates.
Overview
Radeon HD 7750M is a Fast-Middle-Class Mobile Graphics Card based on the First revision of the GCN Architecture.

Architecture
The GCN Architecture succeeds the 40nm Terascale Architecture. In addition to being produced with a 28nm Technology, the GCN Architecture adds other Technologies that allow for energy efficiency. For example, ZeroCore Power, a long idle power saving technology, allows the Graphics Cards to shut down by itself when the Monitor is turned off.
GCN also adds Improved Anisotropic Filtering, DirectX 11 Tessellation and the Partially Resident Textures (PRT) Technology, which enables future games to utilize ultra-high resolution textures with the same performance as today's small and often repetitive textures.

GPU
It equips a GPU codenamed Chelsea PRO which has 8 Compute Units activated and thus offers 512 Shader Processing Units, 32 TMUs and 16 ROPs. The Central Unit Operates at 575MHz.

Memory
The GPU accesses a 1GB frame buffer of fast GDDR5, through a 128-bit memory interface. The size of the frame buffer is adequate. The memory clock operates at 1000MHz.

Features
DirectX 11.0 Support (11.0 Hardware Default) and support for Crossfire, PowerTune Technology, Eyefinity, App Acceleration, HD3D, ZeroCore Power and other technologies.

Power Consumption
With a rated board TDP of 28W, it is suited for 15" or larger laptops.

Performance
Gaming benchmarks put its on average with NVIDIA's GeForce GT 645M.
