In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7770M 2GB are very slightly better than the Nvidia GeForce GT 445M v2.

The HD 7770M has a 105 MHz higher core clock speed and 8 more Texture Mapping Units than the GT 445M. This results in the HD 7770M providing 7.9 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 HD 7770M has a 105 MHz higher core clock speed than the GT 445M and the same number of Render Output Units. This results in the HD 7770M 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 HD 7770M was released over a year more recently than the GT 445M, and so the HD 7770M 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 HD 7770M 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 HD 7770M also has superior memory performance overall.

The HD 7770M has 24 GB/sec greater memory bandwidth than the GT 445M, which means that the memory performance of the HD 7770M is slightly better than the GT 445M.

The Radeon HD 7770M 2GB has 512 Shader Processing Units and the GeForce GT 445M v2 has 144. However, the actual shader performance of the HD 7770M is 294 and the actual shader performance of the GT 445M is 164. The HD 7770M having 130 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7770M delivers a noticeably smoother and more efficient experience when processing graphical data than the GT 445M.

The HD 7770M transistor size technology is 12 nm (nanometers) smaller than the GT 445M. This means that the HD 7770M is expected to run slightly cooler and achieve higher clock frequencies than the GT 445M. While they exhibit similar graphical performance, the HD 7770M should consume less power than the GT 445M.

The Radeon HD 7770M 2GB requires 32 Watts to run and the GeForce GT 445M v2 requires 35 Watts. The GT 445M requires 3 Watts more than the HD 7770M to run. The difference is not significant enough for the GT 445M to have a noticeably larger impact on your yearly electricity bills than the HD 7770M.

GPU Mini Review

Mini ReviewOverview
Radeon HD 7770M 2GB is a Fast-Middle-Class 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 Chelsea XT which has 8 Compute Units activated and thus offers 512 Shader Processing Units, 32 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 32W, it is suited for 15" or larger laptops.

Performance
Gaming benchmarks put its on average with NVIDIA's GeForce GT 650M.

System Suggestions
We recommend a Decent Processor (Intel Core i5 Mobile) and 8GB of RAM for a system with Radeon HD 7770M 2GB.
Overview
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.
