In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R6 7300 are marginally better than the AMD Radeon R5 M255.

The Radeon R5 M255 has a 392 MHz higher core clock speed but 4 fewer Texture Mapping Units than the Radeon R6 7300. The lower TMU count doesn't matter, though, as altogether the Radeon R5 M255 manages to provide 5.7 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 R5 M255 has a 392 MHz higher core clock speed than the Radeon R6 7300 and the same number of Render Output Units. This results in the Radeon R5 M255 providing 3.1 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 Radeon R5 M255 was released less than a year after the Radeon R6 7300, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The Radeon R5 M255 has 4096 MB video memory, but the Radeon R6 7300 does not have an entry, so the two GPUs cannot be reliably compared in this area.

The Radeon R5 M255 has 320 Shader Processing Units and the Radeon R6 7300 has 384. However, the actual shader performance of the Radeon R5 M255 is 256 and the actual shader performance of the Radeon R6 7300 is 133. The Radeon R5 M255 having 123 better shader performance is not particularly notable, as altogether the Radeon R6 7300 performs better when taking into account other relevant data.

The Radeon R5 M255 requires 20 Watts to run and the Radeon R6 7300 requires 20 Watts. The two GPUs require the same amount of wattage to run. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

GPU Mini Review

Mini ReviewRadeon R5 M255 is an entry-level graphics card based on the second revision of the Graphics Core Next architecture.

It offers a core codenamed Sun PRO that packs 320 Shader Processing Units, 20 TMUs and 8 ROPs, on a 64-bit memory interface of DDR3. While the central unit runs at 925MHz and goes up to 940MHz, in Turbo Mode, the memory clock operates at 1000MHz. The regular version should offer 2GB of video memory but expect to see gimmicks of up to 4GB.
Technically R5 M255 is just a higher-clocked Radeon HD 8570M. Due to its very limited performance, even Intel's Iris Graphics Will offer better performance and so it ends up being an useless acquisition.
Radeon R6 7300 is an integrated Graphics Card in the APU A10-7300.

It is based on the Graphics Core Next Architecture and offers 384 Shader Processing Units, 24 TMUs and 8 ROPs. While the central unit is set at 533MHz, 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 800MHz.
The Graphics Card also shares the processor's L2 Cache of 4MB. Therefore, it reduces the need to resort to its memory bandwidth.

Overall, the Graphics Card's performance depends a lot on the system configuration. Best case scenario, expect performance superior to a dedicated NVIDIA GeForce GT 720M or an AMD Radeon R5 M230.
The card is thus suited for 720p gaming and some modern demanding games can be played at least on medium settings.
