Gaming Performance Comparison
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.
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 80 Shader Processing Units and the Radeon HD 7770 2GB GHz Edition has 640. However, the actual shader performance of the Graphics 4600 is 157 and the actual shader performance of the HD 7770 is 544. The HD 7770 having 387 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 Radeon HD 7770 2GB GHz Edition requires 80 Watts to run but there is no entry for the Graphics 4600. We would recommend a PSU with at least 500 Watts for the HD 7770, but we do not have a recommended PSU wattage for the Graphics 4600.
|Mini Review||Intel HD Graphics 4600 Desktop is the successor to Intel HD 4000 Desktop that's featured in the Haswell based desktop CPUs. |
It features 20 Execution Units (80 Shader Processing Units) and its central-unit speed will range between 400MHz and 1250MHz (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.
|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.
