In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7850M are significantly better than the Nvidia GeForce GT 445M v2.

The Radeon HD 7850M has a 105 MHz higher core clock speed and 16 more Texture Mapping Units than the GT 445M. This results in the Radeon HD 7850M providing 13.3 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 Radeon HD 7850M has a 105 MHz higher core clock speed than the GT 445M and the same number of Render Output Units. This results in the Radeon HD 7850M providing 1.7 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 7850M was released over a year more recently than the GT 445M, and so the Radeon HD 7850M is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GT 445M.

The Radeon HD 7850M has 1024 MB more video memory than the GT 445M, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the Radeon HD 7850M also has superior memory performance overall.

The Radeon HD 7850M has 24 GB/sec greater memory bandwidth than the GT 445M, which means that the memory performance of the Radeon HD 7850M is slightly better than the GT 445M.

The GeForce GT 445M v2 has 144 Shader Processing Units and the Radeon HD 7850M has 640. However, the actual shader performance of the GT 445M is 164 and the actual shader performance of the Radeon HD 7850M is 367. The Radeon HD 7850M having 203 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon HD 7850M delivers a noticeably smoother and more efficient experience when processing graphical data than the GT 445M.

The Radeon HD 7850M transistor size technology is 12 nm (nanometers) smaller than the GT 445M. This means that the Radeon HD 7850M is expected to run slightly cooler and achieve higher clock frequencies than the GT 445M.

The GeForce GT 445M v2 requires 35 Watts to run and the Radeon HD 7850M requires 40 Watts. The Radeon HD 7850M requires 5 Watts more than the GT 445M to run. The difference is not significant enough for the Radeon HD 7850M to have a noticeably larger impact on your yearly electricity bills than the GT 445M.

GPU Mini Review

Mini ReviewOverview
GeForce GT 445M v2 is a Fast-Middle-Class Mobile Graphics Card based on the first revision of the Fermi Architecture.

Architecture
The Fermi Architecture is manufactured with a 40nm technology and uses a technique known as Hot Clocking: The Shaders are clocked twice as fast as the Central Unit. While this leads to a reasonable performance boost, it causes enormous amounts of energy dissipation, leading, ultimately, to a significantly higher operating temperature.
Fermi is also the first GPU architecture with fully cached memory access which increases memory performance.

GPU
It equips a GPU Codenamed GF106-N11E-GE-A1 which has 3 Stream Multiprocessors activated and thus offers 144 Shader Processing Units, 24 TMUs and 16 ROPs. The Central Unit is clocked at 570MHz.

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 625MHz.

Features
DirectX 11.0 Support (11.0 Hardware Default) and support for Optimus, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies

Power Consumption
With a rated board TDP of 35W, it is suited for 15" or larger laptops.

Performance
Gaming benchmarks put its performance almost on level with the desktop GeForce GT 450 v4.

System Suggestions
We recommend a decent processor (Intel Core i5 Mobile) and 4GB of RAM for a system with GeForce GT 445M v2.
Overview
Radeon HD 7850M is a Performance Mobile Graphics Card based on the First revision of the GCN Architecture.

Architecture
The GCN Architecture succeeds the 40nm Terascale Architecture. In addition to being produced with a 28nm Technology, the GCN Architecture adds other Technologies that allow for energy efficiency. For example, ZeroCore Power, a long idle power saving technology, allows the Graphics Cards to shut down by itself when the Monitor is turned off.
GCN also adds Improved Anisotropic Filtering, DirectX 11 Tessellation and the Partially Resident Textures (PRT) Technology, which enables future games to utilize ultra-high resolution textures with the same performance as today's small and often repetitive textures.

GPU
It equips a GPU codenamed Heathrow Pro which has 10 Compute Units activated and thus offers 640 Shader Processing Units, 40 TMUs and 16 ROPs. The Central Unit Operates at 675MHz.

Memory
The GPU accesses a 2GB frame buffer of fast GDDR5, 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 40W, it is suited for 17" or larger laptops.

Performance
Gaming benchmarks put its on average with NVIDIA's GeForce GTX 660M.

System Suggestions
We recommend a Decent Processor (Intel Core i5 Mobile) and 8GB of RAM for a system with Radeon HD 7850M.
