In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 770M SLI are massively better than the AMD Radeon HD 8850M.

The GTX 770M has a 186 MHz higher core clock speed and 120 more Texture Mapping Units than the Radeon HD 8850M. This results in the GTX 770M providing 104.8 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 GTX 770M has a 186 MHz higher core clock speed and 32 more Render Output Units than the Radeon HD 8850M. This results in the GTX 770M providing 28.9 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 GTX 770M was released less than a year after the Radeon HD 8850M, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GTX 770M has 2048 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 770M also has superior memory performance overall.

The GTX 770M has 160 GB/sec greater memory bandwidth than the Radeon HD 8850M, which means that the memory performance of the GTX 770M is massively better than the Radeon HD 8850M.

The Radeon HD 8850M has 640 Shader Processing Units and the GeForce GTX 770M SLI has 1920. However, the actual shader performance of the Radeon HD 8850M is 496 and the actual shader performance of the GTX 770M is 1557. The GTX 770M having 1061 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 770M delivers a massively smoother and more efficient experience when processing graphical data than the Radeon HD 8850M.

The Radeon HD 8850M requires 45 Watts to run and the GeForce GTX 770M SLI requires 150 Watts. The GTX 770M requires 105 Watts more than the Radeon HD 8850M to run. The difference is significant enough that the GTX 770M may have an adverse affect on your yearly electricity bills in comparison to 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.

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 GTX 770M SLI is a combination of 2 GeForce GTX 770M put together using NVIDIA's SLI technology.
Together, this combination offers 1920 Shader Processing Units, 160 TMUs and 48 ROPs. This, on a 192-bit memory interface, per card, of fast GDDR5. While the central unit runs at 811MHz and goes up to XXXMHz, in Turbo Mode, the memory clock operates at 1000MHz.
Best case scenario, this combination is expected to perform better a single GeForce GTX 780M and deliver similar performance to a desktop GeForce GTX 680 but ultimately, its performance depends on the driver support and on the 3D application.
Therefore, and paired with a powerful processor, all demanding games should be playable at the highest settings. Still, this combination might surpass the 150W barrier of TDP and therefore require more power than a single GeForce GTX 780M, though delivering better performance.
