In terms of overall gaming performance, the graphical capabilities of the Intel Iris Graphics 540 Mobile are very slightly better than the AMD Radeon HD 6850M.

The Radeon HD 6850M has a 375 MHz higher core clock speed and 32 more Texture Mapping Units than the Graphics 540. This results in the Radeon HD 6850M providing 24.6 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 HD 6850M has a 375 MHz higher core clock speed and 14 more Render Output Units than the Graphics 540. This results in the Radeon HD 6850M providing 10.2 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 540 was released over three years more recently than the Radeon HD 6850M, and so the Graphics 540 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 HD 6850M has 960 MB more video memory than the Graphics 540, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the Graphics 540 has superior memory performance.

The Graphics 540 has 8.5 GB/sec greater memory bandwidth than the Radeon HD 6850M, which means that the memory performance of the Graphics 540 is marginally better than the Radeon HD 6850M.

The Iris Graphics 540 Mobile has 48 Shader Processing Units and the Radeon HD 6850M has 800. However, the actual shader performance of the Graphics 540 is 403 and the actual shader performance of the Radeon HD 6850M is 270. The Graphics 540 having 133 better shader performance is not particularly notable, as altogether the Radeon HD 6850M performs better when taking into account other relevant data.

The Graphics 540 transistor size technology is 26 nm (nanometers) smaller than the Radeon HD 6850M. This means that the Graphics 540 is expected to run slightly cooler and achieve higher clock frequencies than the Radeon HD 6850M. While they exhibit similar graphical performance, the Graphics 540 should consume less power than the Radeon HD 6850M.

The Iris Graphics 540 Mobile requires 15 Watts to run and the Radeon HD 6850M requires 50 Watts. The Radeon HD 6850M requires 35 Watts more than the Graphics 540 to run. The difference is significant enough that the Radeon HD 6850M may have a slight adverse affect on your yearly electricity bills in comparison to the Graphics 540.

GPU Mini Review

Mini ReviewOverview
Intel Iris Graphics 540 Mobile are Integrated Graphics in some of Intel's Skylake Mobile Processors.

The Skylake Architecture succeeds the Broadwell Architecture and aims for increased CPU and Graphics Performance, within the same Power Requirements. It includes support for DirectX 12.1, OpenCL 2.0 and OpenGL 4.4, as well as DDR4 Memory Support.
The GPU Codenamed GT3-U offers 48 Shader Processing Units, 8 TMUs and 2 ROPs.

The Central Unit Initially Runs at 350MHz and goes up to 1050MHz, in Turbo Mode.

Memory: Speed
The Operating Memory Clock depends at which speed the System's RAM is running and which Memory Type is installed and is ultimately limited by the highest operating speed that the Processor supports. In this case, it is 933MHz for DDR3 and 1067MHz for DDR4.
Depending on whether or not the System's RAM is Dual-Channeled, it can access either a 64-bit or 128-bit Memory Interface.
An addition to the Iris Graphics is the access to a L4 Cache of 64MB eDRAM which further increases the Memory Performance.

Memory: Frame Buffer
The GPU Shares the System's RAM which varies according to the System. The GPU may reserve up to 1.7GB.

Because Performance depends heavily on the Memory Bandwidth, it may vary heavily from System to System.
Best Case Scenario, expect Performance Identical to a dedicated GeForce 830M.

System Suggestions
Intel Iris Graphics 540 Mobile is best suited for resolutions up to and including 1366x768. We recommend 4GB of RAM for Optimal Performance.
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+).
