In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 8850M are massively better than the Nvidia GeForce Go 7800.

The Radeon HD 8850M was released over three years more recently than the GeForce Go 7800, 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 GeForce Go 7800 when running the latest games.

The Radeon HD 8850M has 1792 MB more video memory than the GeForce Go 7800, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The GeForce Go 7800 has 3.2 GB/sec greater memory bandwidth than the Radeon HD 8850M, which means that the memory performance of the GeForce Go 7800 is marginally better than the Radeon HD 8850M.

The Radeon HD 8850M has 640 Shader Processing Units but the GeForce Go 7800 does not have an entry, so the two GPUs cannot be reliably compared in this area.

The Radeon HD 8850M requires 45 Watts to run and the GeForce Go 7800 requires 35 Watts. The Radeon HD 8850M requires 10 Watts more than the GeForce Go 7800 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 GeForce Go 7800.

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.
GeForce Go 7800 is a fast middle-class level GPU.
It can use up to 256MB of dedicated video memory, and it's only available with a DDR3 memory type + a 256 bits Memory Bus Width.
Due to its features and unlike the previous GeForce Go models, it should be able to play all old games (before 2006) smoothly at the highest settings but it might not be good enough to play of today's games at the lowest settings, due to the limited memory size and DirectX support.
