In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7770 2GB GHz Edition are massively better than the Intel HD Graphics 4600 Desktop.
The HD 7770 has a 600 MHz higher core clock speed and 36 more Texture Mapping Units than the Graphics 4600. This results in the HD 7770 providing 38.4 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 HD 7770 has a 600 MHz higher core clock speed and 14 more Render Output Units than the Graphics 4600. This results in the HD 7770 providing 15.2 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 HD 7770, 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 HD 7770.
The HD 7770 has 2048 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 Desktop has 20 Shader Processing Units and the Radeon HD 7770 2GB GHz Edition has 640. However, the actual shader performance of the Graphics 4600 is 100 and the actual shader performance of the HD 7770 is 544. The HD 7770 having 444 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7770 delivers a massively 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 HD 7770. This means that the Graphics 4600 is expected to run very slightly cooler and achieve higher clock frequencies than the HD 7770.
The HD Graphics 4600 Desktop requires 88 Watts to run and the Radeon HD 7770 2GB GHz Edition requires 80 Watts. We would recommend a PSU with at least 300 Watts for the Graphics 4600 and a PSU with at least 500 Watts for the HD 7770. The Graphics 4600 requires 8 Watts more than the HD 7770 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 HD 7770.

|Mini Review||Overview |
Intel HD Graphics 4600 Desktop are Integrated Graphics in some of Intel's Desktop Haswell Processors.
The Haswell GT2 Core includes support for DirectX 11.1, OpenCL 1.2 and OpenGL 4.0. 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 1250MHz, 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 220.

We recommend 4GB of RAM for a system with Intel HD Graphics 4600 Desktop.
|Radeon HD 7770 2GB GHz Edition is a variant of the Radeon HD 7770 GHz Edition aka just Radeon HD 7770. |
The only difference between this version and the original is the increase in the video memory that was doubled from 1GB to 2GB.
It's proved that extra memory for this GPU does not yield extra performance. Therefore, this GPU's performance is exactly like the standards.
