In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 M270X are significantly better than the AMD Radeon HD 6850M.

The Radeon R9 M270X has a 50 MHz higher core clock speed and 8 more Texture Mapping Units than the Radeon HD 6850M. This results in the Radeon R9 M270X providing 7.8 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 Radeon R9 M270X has a 50 MHz higher core clock speed than the Radeon HD 6850M and the same number of Render Output Units. This results in the Radeon R9 M270X providing 0.8 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 Radeon R9 M270X was released over three years more recently than the Radeon HD 6850M, and so the Radeon R9 M270X is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the Radeon HD 6850M when running the latest games.

The Radeon R9 M270X has 1024 MB more video memory than the Radeon HD 6850M, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the Radeon R9 M270X also has superior memory performance overall.

The Radeon R9 M270X has 38.4 GB/sec greater memory bandwidth than the Radeon HD 6850M, which means that the memory performance of the Radeon R9 M270X is noticeably better than the Radeon HD 6850M.

The Radeon R9 M270X has 640 Shader Processing Units and the Radeon HD 6850M has 800. However, the actual shader performance of the Radeon R9 M270X is 496 and the actual shader performance of the Radeon HD 6850M is 270. The Radeon R9 M270X having 226 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon R9 M270X delivers a significantly smoother and more efficient experience when processing graphical data than the Radeon HD 6850M.

The Radeon R9 M270X transistor size technology is 12 nm (nanometers) smaller than the Radeon HD 6850M. This means that the Radeon R9 M270X is expected to run slightly cooler and achieve higher clock frequencies than the Radeon HD 6850M.

The Radeon R9 M270X requires 50 Watts to run and the Radeon HD 6850M requires 50 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 R9 M270X is an upcoming high-end mobile graphics Card, based on the 28nm GCN architecture.
Radeon R9 M270X offers a GPU codenamed Venus xT which is at essence a mobile version of the Cape Verde XT GPU. Thus, it offers 640 Shader Processing Units, 40 TMUs and 16 ROPs, on a 128-bit memory interface of fast GDDR5.
The central unit runs at 725MHz and goes up to 775MHz, in Turbo Mode, while the memory clock operates at 1000MHz. Expect a rated board TDP of 60W.
Its performance is therefore positioned between Radeon 7750 and Radeon 7770 and thus the card is not suited for 1080p gaming but it needs to be paired with at least 8GB of RAM and a considerably powerful Dual-Core processor.
Radeon HD 6850M is a high-end GPU based on the 40nm Terrascale 2 architecture.
It's based on the Juniper Core (therefore related to Radeon HD 6770) and offers 800 Shader Processing Units, 40 TMUs and 16 ROPs on a 128-bit memory interface. Though fast GDDR5 is supported, the most common version features standard DDR3 but comes higher clocked. Its central clock runs at 675MHz and the memory clock operates at 800MHz.
Compared to Radeon HD 6850M, its performance is considerably slower due to being paired with standard DDR3 and the power consumption should remain similar since GDDR5 is more energy efficient.
Using a 720p resolution, most of today's games are only playable at medium settings but with very fluent frame rates (45+).
