In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 8850M are massively better than the AMD Mobility Radeon HD 3670.

The Radeon HD 8850M was released over three years more recently than the Radeon HD, and so the Radeon HD 8850M is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the Radeon HD when running the latest games.

The Radeon HD 8850M has 1536 MB more video memory than the Radeon HD, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the Radeon HD 8850M also has superior memory performance overall.

The Radeon HD 8850M has 6.4 GB/sec greater memory bandwidth than the Radeon HD, which means that the memory performance of the Radeon HD 8850M is marginally better than the Radeon HD.

The Radeon HD 8850M has 640 Shader Processing Units and the Mobility Radeon HD 3670 has 120. However, the actual shader performance of the Radeon HD 8850M is 496 and the actual shader performance of the Radeon HD is 82. The Radeon HD 8850M having 414 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon HD 8850M delivers a noticeably smoother and more efficient experience when processing graphical data than the Radeon HD.

The Radeon HD 8850M requires 45 Watts to run and the Mobility Radeon HD 3670 requires 30 Watts. The Radeon HD 8850M requires 15 Watts more than the Radeon HD to run. The difference is not significant enough for the Radeon HD 8850M to have a noticeably larger impact on your yearly electricity bills than the Radeon HD.

GPU Mini Review

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

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.

GPU
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.

Memory
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.

Features
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.

Performance
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.
The ATI Mobility Radeon HD 3000 Series of discrete graphics allow you to experience the power of HD with graphics processing designed for how you work and play. Advance to the next generation of HD game performance and lifelike realism thanks to Microsoft DirectX 10.1 capabilities and PCI Express 2.0 support for fast throughput and superior overall system performance. Watch the latest Blu-ray and HD-DVD videos in full-HD 1080p image resolution off your graphics processor and reduce demands on your CPU. Enjoy breakthrough energy efficiency with superb performance-per-watt delivering exceptional battery life.
