In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7850 XFX Core Edition are massively better than the Intel Iris Graphics 5100 Desktop.

The HD 7850 has a 460 MHz higher core clock speed and 56 more Texture Mapping Units than the Graphics 5100. This results in the HD 7850 providing 51.8 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 7850 has a 460 MHz higher core clock speed and 28 more Render Output Units than the Graphics 5100. This results in the HD 7850 providing 25.9 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 5100 was released over a year more recently than the HD 7850, and so the Graphics 5100 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 7850.

The HD 7850 has 1024 MB video memory, but the Graphics 5100 does not have an entry, so the two GPUs cannot be reliably compared in this area.

The Iris Graphics 5100 Desktop has 160 Shader Processing Units and the Radeon HD 7850 XFX Core Edition has 1024. However, the actual shader performance of the Graphics 5100 is 314 and the actual shader performance of the HD 7850 is 749. The HD 7850 having 435 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 Graphics 5100.

The Graphics 5100 transistor size technology is 6 nm (nanometers) smaller than the HD 7850. This means that the Graphics 5100 is expected to run very slightly cooler and achieve higher clock frequencies than the HD 7850.

The Iris Graphics 5100 Desktop requires 28 Watts to run but there is no entry for the Radeon HD 7850 XFX Core 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 Graphics 5100.

GPU Mini Review

Mini ReviewIris Graphics 5100 Desktop are found in some of the 2013 Haswell desktop processors.
They feature 40 Execution Units (160 Shader Processing Units), 8 TMUs and 4 ROPs. They share system memory and so the memory channel and speed will depend on the users configuration. The best possible combination is a dual-channel bus-width with an operating memory clock of 800MHz.
Its central unit and turbo frequency also depend on the CPU its embedded but it ranges from 400MHz to 1350MHz.
Its performance is average and only somewhat better than what dedicated GeForce GT 630 & Radeon 6570 offer.
Radeon HD 7850 XFX Core Edition is a special edition of the powerful Radeon HD 7850. See the standard version for more information about it.
This edition features a special cooling system that allows twice as much heat dissipation when compared to the reference AMD cooling system but its performance is still the same, as there's no over-clocking out of the box.
