Gaming Performance Comparison
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 375 MHz higher core clock speed and 28 more Texture Mapping Units than the Graphics 4600. This results in the Radeon HD 7750M providing 17.6 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 375 MHz higher core clock speed and 14 more Render Output Units than the Graphics 4600. This results in the Radeon HD 7750M providing 8.8 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 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 when compared to the Radeon HD 7750M.
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 20 Shader Processing Units and the Radeon HD 7750M has 512. However, the actual shader performance of the Graphics 4600 is 108 and the actual shader performance of the Radeon HD 7750M is 250. The Radeon HD 7750M having 142 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 47 Watts to run and the Radeon HD 7750M requires 28 Watts. The Graphics 4600 requires 19 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.
|Mini Review||Overview |
Intel HD Graphics 4600 Mobile are Integrated Graphics in some of Intel's Mobile Haswell Processors.
The Haswell GT2 Core includes support for DirectX 11.1, OpenCL 1.2 and OpenGL 4.3. Additionally, it also offers better Decoding Performance, when compared to its Predecessors.
It equips a GPU Codenamed GT2 which offers 20 Shader Processing Units, 4 TMUs and 2 ROPs. The Central Unit Initially Runs at 200MHz and goes up to 1350MHz, in Turbo Mode.
The GPU Shares the System's RAM which varies from System to System. Typically, the GPU reserves 1.7GB. Depending on whether or not the system's RAM is Dual-Channeled, it can access either a 64-bit or 128-bit memory interface. The operating memory clock also depends on which speed the System's RAM is running and is limited by the highest operating speed that the Processor supports. In this case, it is 800MHz.
It is then obvious the Memory Bandwidth depends on a lot of factors and thus this Graphics Card performance may vary heavily from system to system.
The Most Powerful Variant Offers Performance similar to a dedicated GeForce GT 540M.

We recommend 4GB of RAM for a system with Intel HD Graphics 4600 Mobile.
Radeon HD 7750M is a Fast-Middle-Class Mobile Graphics Card based on the First revision of the GCN 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.
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.
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.
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 28W, it is suited for 15" or larger laptops.
Gaming benchmarks put its on average with NVIDIA's GeForce GT 645M.
We recommend a Decent Processor (Intel Core i5 Mobile) and 8GB of RAM for a system with Radeon HD 7750M.
