In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 670M 3GB are significantly better than the AMD Radeon HD 8850M.

The Radeon HD 8850M was released over a year more recently than the GTX 670M, and so the Radeon HD 8850M is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 670M.

The GTX 670M has 1024 MB more video memory than the Radeon HD 8850M, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 670M also has superior memory performance overall.

The GTX 670M has 40 GB/sec greater memory bandwidth than the Radeon HD 8850M, which means that the memory performance of the GTX 670M is noticeably better than the Radeon HD 8850M.

The Radeon HD 8850M has 640 Shader Processing Units and the GeForce GTX 670M 3GB has 336. However, the actual shader performance of the Radeon HD 8850M is 496 and the actual shader performance of the GTX 670M is 402. The Radeon HD 8850M having 94 better shader performance is not particularly notable, as altogether the GTX 670M performs better when taking into account other relevant data.

The Radeon HD 8850M transistor size technology is 12 nm (nanometers) smaller than the GTX 670M. This means that the Radeon HD 8850M is expected to run slightly cooler and achieve higher clock frequencies than the GTX 670M.

The Radeon HD 8850M requires 45 Watts to run and the GeForce GTX 670M 3GB requires 75 Watts. The GTX 670M requires 30 Watts more than the Radeon HD 8850M to run. The difference is not significant enough for the GTX 670M to have a noticeably larger impact on your yearly electricity bills than the Radeon HD 8850M.

GPU Mini Review

Mini ReviewOverview
Radeon HD 8850M is a Performance Mobile Graphics Card based on the Second Revision of the GCN Architecture.

The GCN 1.1 Release adds support for AMD's TrueAudio Technology which does calculations of audio effects "better" than the CPU and further improves the Powertune Technology.

It equips a GPU codenamed Venus PRO which has 10 Compute Units activated and thus offers 640 Shader Processing Units, 40 TMUs and 16 ROPs. The Central Unit Initially Operates at 625MHz and goes up to 775MHz, in Turbo Mode.

The GPU accesses a 2GB frame buffer of DDR3, through a 128-bit memory interface. The size of the frame buffer is exaggerated and in no way benefits the GPU. The memory clock operates at 1000MHz.

DirectX 11.0 Support (11.0 Hardware Default) and support for Crossfire, PowerTune Technology, Eyefinity, App Acceleration, HD3D, ZeroCore Power and other technologies.

Power Consumption
With a rated board TDP of 45W, it is suited for 17" or larger laptops.

Gaming benchmarks put its performance somewhat above NVIDIA's GeForce GT 750M.

System Suggestions
We recommend a Decent Processor (Intel Core i5 Mobile) and 8GB of RAM for a system with Radeon HD 8850M.
GeForce GTX 670M 3GB is a high-end mobile GPU still based on the 2010 Fermi architecture.
It's based on the Fermi GF114 Core which offers 336 Shader Processing Units, 56 TMUs and 24 ROPs on a 192-bit memory interface of 3GB GDDR5 (which is a gimmick since this GPU does not benefit from a 2GB frame buffer, let alone 3GB). The central clock runs at 598MHz and the memory clock operates at 750MHz. Expect a power consumption of up to 75 Watts.
It's essentially a tweaked GeForce GTX 570M with a slightly higher clocked central unit that consumes the same power and so expect modern demanding games to be playable at 1080p with fluent frame rates (30+).
