In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 650M Mac 1GB Edition are very slightly better than the AMD Radeon HD 8850M.

The GT 650M has a 275 MHz higher core clock speed but 8 fewer Texture Mapping Units than the Radeon HD 8850M. The lower TMU count doesn't matter, though, as altogether the GT 650M manages to provide 3.8 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 GT 650M has a 275 MHz higher core clock speed than the Radeon HD 8850M and the same number of Render Output Units. This results in the GT 650M providing 4.4 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 Radeon HD 8850M was released less than a year after the GT 650M, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The Radeon HD 8850M has 1024 MB more video memory than the GT 650M, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the GT 650M has superior memory performance.

The GT 650M has 48.3 GB/sec greater memory bandwidth than the Radeon HD 8850M, which means that the memory performance of the GT 650M is noticeably better than the Radeon HD 8850M.

The GeForce GT 650M Mac 1GB Edition has 384 Shader Processing Units and the Radeon HD 8850M has 640. However, the actual shader performance of the GT 650M is 346 and the actual shader performance of the Radeon HD 8850M is 496. The Radeon HD 8850M having 150 better shader performance is not particularly notable, as altogether the GT 650M performs better when taking into account other relevant data.

The GeForce GT 650M Mac 1GB Edition requires 45 Watts to run and the Radeon HD 8850M requires 45 Watts. The two GPUs require the same amount of wattage to run. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

GPU Mini Review

Mini ReviewOverview
GeForce GT 650M Mac 1GB Edition is a Fast-Middle-Class Mobile Graphics Card based on the first revision of the Kepler Architecture.

Architecture
The Kepler Architecture was NVIDIA's big step to power efficiency. Each Stream Multiprocessor (SMX) now hosts 192 Shader Processing Units - against the 48 of older Fermi Architecture, and has been redesigned being now clocked at the same speed of the Central Unit. This means they are more energy efficient and will consequently lead to cooler operating temperatures. However, it also means they are weaker. It can be said that one Fermi SMX is as fast as 2 Kepler SMXs.
Additionally, and not available in all GPUs, Kepler also introduced the Boost Clock Feature. The Boost Clock is an even higher Clock Speed activated when in gaming mode and becomes the effective speed of the GPU.

GPU
It equips a GPU Codenamed GK107 which has 2 Stream Multiprocessors activated and thus offers 384 Shader Processing Units, 32 TMUs and 16 ROPs. The Central Unit is clocked at 900MHz.

Memory
The GPU accesses a 1GB frame buffer of fast GDDR5, through a 128-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 1254MHz.

Power Consumption
With a rated board TDP of 45W, it is suited for average sized laptops.

Performance
Gaming benchmarks indicate its performance is similar to GeForce GTX 660M.

System Suggestions
We recommend a decent processor and 8GB of RAM for a system with GeForce GT 650M Mac 1GB Edition.
Overview
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.
