In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R5 M255 are significantly better than the Intel HD Graphics Mobile (Broadwell).

The Radeon R5 M255 has a 625 MHz higher core clock speed and 16 more Texture Mapping Units than the Graphics Mobile. This results in the Radeon R5 M255 providing 17.3 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 Radeon R5 M255 has a 625 MHz higher core clock speed and 6 more Render Output Units than the Graphics Mobile. This results in the Radeon R5 M255 providing 6.8 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 Graphics Mobile was released less than a year after the Radeon R5 M255, 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 Graphics Mobile does not have an entry, so the two GPUs cannot be reliably compared in this area.

The HD Graphics Mobile (Broadwell) has 12 Shader Processing Units and the Radeon R5 M255 has 320. However, the actual shader performance of the Graphics Mobile is 10 and the actual shader performance of the Radeon R5 M255 is 256. The Radeon R5 M255 having 246 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon R5 M255 delivers a marginally smoother and more efficient experience when processing graphical data than the Graphics Mobile.

The Graphics Mobile transistor size technology is 6 nm (nanometers) smaller than the Radeon R5 M255. This means that the Graphics Mobile is expected to run very slightly cooler and achieve higher clock frequencies than the Radeon R5 M255.

The HD Graphics Mobile (Broadwell) requires 4 Watts to run and the Radeon R5 M255 requires 20 Watts. The Radeon R5 M255 requires 16 Watts more than the Graphics Mobile to run. The difference is not significant enough for the Radeon R5 M255 to have a noticeably larger impact on your yearly electricity bills than the Graphics Mobile.

GPU Mini Review

Mini ReviewIntel HD Graphics Mobile (Broadwell) are integrated graphics in the budget Celeron and Pentium Broadwell Mobile processors.
Their performance depends on the processor they are integrated on, as the latter defines the Base and Boost Clock, as well as on the SYSTEM RAM, which defines the operating memory clock, and whether the GPU accesses a 64-bit or 128-bit memory interface.
Best case scenario, the Intel HD Graphics Mobile (Broadwell) performs on par with Intel HD 4000 Graphics and so most modern demanding games will not be playable. Less graphically intense games will be playable at lower graphics settings.
Radeon 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.
