In terms of overall gaming performance, the graphical capabilities of the Intel HD Graphics 4600 Desktop are significantly better than the AMD Radeon HD 3650.

The Radeon HD 3650 has a 325 MHz higher core clock speed and 4 more Texture Mapping Units than the Graphics 4600. This results in the Radeon HD 3650 providing 4.2 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 3650 has a 325 MHz higher core clock speed and 2 more Render Output Units than the Graphics 4600. This results in the Radeon HD 3650 providing 2.1 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 three years more recently than the Radeon HD 3650, and so the Graphics 4600 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the Radeon HD 3650 when running the latest games.

The Radeon HD 3650 has 256 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 3650 has 120. However, the actual shader performance of the Graphics 4600 is 157 and the actual shader performance of the Radeon HD 3650 is 87. The Graphics 4600 having 70 better shader performance and an altogether better performance when taking into account other relevant data means that the Graphics 4600 delivers a marginally smoother and more efficient experience when processing graphical data than the Radeon HD 3650.

The Graphics 4600 transistor size technology is 33 nm (nanometers) smaller than the Radeon HD 3650. This means that the Graphics 4600 is expected to run much cooler and achieve higher clock frequencies than the Radeon HD 3650.

The Radeon HD 3650 requires 65 Watts to run but there is no entry for the Graphics 4600. We would recommend a PSU with at least 400 Watts for the Radeon HD 3650, but we do not have a recommended PSU wattage for the Graphics 4600.

GPU Mini Review

Mini ReviewIntel 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 3650 is a fast-middle-class GPU based on the 55nm, second unified shader architecture, R600.
It's based on the RV635 PRO Core and offers 120 Shader Processing Units, 8 TMUs and 4 ROPs a 128-bit memory interface of standard GDDR3. The central unit runs at 725MHz and the memory clock runs at up to 800MHz.
Its performance is relatively below the average and so today's modern games will have to be played at modest resolutions from low to medium settings. DirectX 11 games aren't supported.
