In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7850 XFX Ultra OC Edition are massively better than the Intel UHD Graphics 630.

The HD 7850 has a 625 MHz higher core clock speed and 41 more Texture Mapping Units than the UHD Graphics 630. This results in the HD 7850 providing 54.3 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 7850 has a 625 MHz higher core clock speed and 29 more Render Output Units than the UHD Graphics 630. This results in the HD 7850 providing 30.1 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 UHD Graphics 630 was released over three years more recently than the HD 7850, and so the UHD Graphics 630 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 7850 when running the latest games.

The HD 7850 has 1024 MB video memory, but the UHD Graphics 630 does not have an entry, so the two GPUs cannot be reliably compared in this area.

The UHD Graphics 630 has 184 Shader Processing Units and the Radeon HD 7850 XFX Ultra OC Edition has 1024. However, the actual shader performance of the UHD Graphics 630 is 212 and the actual shader performance of the HD 7850 is 849. The HD 7850 having 637 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7850 delivers a massively smoother and more efficient experience when processing graphical data than the UHD Graphics 630.

The UHD Graphics 630 transistor size technology is 14 nm (nanometers) smaller than the HD 7850. This means that the UHD Graphics 630 is expected to run slightly cooler and achieve higher clock frequencies than the HD 7850.

The UHD Graphics 630 requires 15 Watts to run but there is no entry for the Radeon HD 7850 XFX Ultra OC Edition. We would recommend a PSU with at least 500 Watts for the HD 7850, but we do not have a recommended PSU wattage for the UHD Graphics 630.
