In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7850 XFX Core Edition are massively better than the AMD Radeon R5 7400K.

The HD 7850 has a 104 MHz higher core clock speed and 48 more Texture Mapping Units than the Radeon R5 7400K. This results in the HD 7850 providing 42.9 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 104 MHz higher core clock speed and 24 more Render Output Units than the Radeon R5 7400K. This results in the HD 7850 providing 21.5 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 Radeon R5 7400K was released over a year more recently than the HD 7850, and so the Radeon R5 7400K 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 Radeon R5 7400K does not have an entry, so the two GPUs cannot be reliably compared in this area.

The Radeon R5 7400K has 256 Shader Processing Units and the Radeon HD 7850 XFX Core Edition has 1024. However, the actual shader performance of the Radeon R5 7400K is 126 and the actual shader performance of the HD 7850 is 749. The HD 7850 having 623 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 Radeon R5 7400K.

The Radeon R5 7400K requires 65 Watts to run but there is no entry for the Radeon HD 7850 XFX Core Edition. We would recommend a PSU with at least 300 Watts for the Radeon R5 7400K and a PSU with at least 500 Watts for the HD 7850. The HD 7850 has been recommended a PSU with 200 Watts more than the Radeon R5 7400K. The difference is significant enough that the HD 7850 may have an adverse affect on your yearly electricity bills in comparison to the Radeon R5 7400K.

GPU Mini Review

Mini ReviewRadeon R5 7400K is an integrated Graphics Card in the A4-7400K.
It is based on the Graphics Core Next Architecture and offers 256 Shader Processing Units, XX TMUs and X ROPs. The memory bus-width will depend on whether or not the system's RAM is dual-channeled and the operating memory clock, on its frequency. Thus, it can be either 64-bit or 128-bit and up to 933MHz.
Therefore, the Graphics Card's performance depends a lot on the system configuration. Best case scenario, expect performance superior to Intel's powerful Iris Graphics 5100.
The card is thus suited for 720p gaming and some modern demanding games can be played at least on medium settings.
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.
