In terms of overall gaming performance, the graphical capabilities of the Intel UHD Graphics 630 are noticeably better than the AMD Radeon HD 2900 XT 512MB.

The HD 2900 XT has a 393 MHz higher core clock speed but 7 fewer Texture Mapping Units than the UHD Graphics 630. The lower TMU count doesn't matter, though, as altogether the HD 2900 XT manages to provide 3.8 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 2900 XT has a 393 MHz higher core clock speed and 13 more Render Output Units than the UHD Graphics 630. This results in the HD 2900 XT providing 10.8 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 UHD Graphics 630 was released over three years more recently than the HD 2900 XT, 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 2900 XT when running the latest games.

The HD 2900 XT has 512 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 2900 XT 512MB has 320. However, the actual shader performance of the UHD Graphics 630 is 212 and the actual shader performance of the HD 2900 XT is 155. The UHD Graphics 630 having 57 better shader performance is not particularly notable, as altogether the HD 2900 XT performs better when taking into account other relevant data.

The UHD Graphics 630 transistor size technology is 66 nm (nanometers) smaller than the HD 2900 XT. This means that the UHD Graphics 630 is expected to run massively cooler and achieve higher clock frequencies than the HD 2900 XT.

The UHD Graphics 630 requires 15 Watts to run and the Radeon HD 2900 XT 512MB requires 215 Watts. We would recommend a PSU with at least 550 Watts for the HD 2900 XT, but we do not have a recommended PSU wattage for the UHD Graphics 630. The HD 2900 XT requires 200 Watts more than the UHD Graphics 630 to run. The difference is significant enough that the HD 2900 XT may have an adverse affect on your yearly electricity bills in comparison to the UHD Graphics 630.

GPU Mini Review

Mini ReviewOverview Intel UHD Graphics 630 are Integrated Graphics in some of Intel's Coffee Lake Processors. Architecture The Coffee Lake Architecture succeeds the Kaby Lake Architecture and aims for increased CPU and Graphics Performance, within the same Power Requirements. It includes support for DirectX 12.1, OpenCL 2.1 and OpenGL 4.6, as well as DDR4 Memory Support. GPU The central unit initially runs at 300MHz and goes up to 1150MHz in Turbo Mode. The GPU Codenamed GT2 offers 184 Shader Processing Units, 23 TMUs and 3 ROPs Memory Speed The operating memory clock depends on which speed the System's RAM is running and which memory type is installed and is ultimately limited by the highest operating speed that the processor supports. Depending on whether or not the System's RAM is Dual-Channeled, it can access either a 64-bit or 128-bit Memory Interface. Memory Frame Buffer The GPU Shares the System's RAM which varies according to the System. The GPU may reserve up to 1.7GB.Radeon HD 2900 XT 512MB is a high-end GPU based on the 80nm variant of the second unified shader architecture, R600.
It's based on the R600 XT Core and offers 320 Shader Processing Units, 16 TMUs and 16 ROPs on a 512-bit memory interface of standard GDDR3. The central unit runs at 743MHz and the memory clock runs at up to 828MHz.
Its performance is somewhat faster than Radeon HD 2900 Pro due to being higher clocked and the extra memory bandwidth is bottlenecked by the small sized frame buffer and thus most games have to be played using a 1024x768 resolution but should be playable at high settings.
