In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 M275 are significantly better than the Nvidia GeForce GT 445M v2.

The Radeon R9 M275 has no core clock speed set, so any comparison between Texture and Pixel Fill Rates is not currently possible.

The Radeon R9 M275 was released over three years more recently than the GT 445M, and so the Radeon R9 M275 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GT 445M when running the latest games.

The Radeon R9 M275 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 R9 M275 also has superior memory performance overall.

The Radeon R9 M275 has 24 GB/sec greater memory bandwidth than the GT 445M, which means that the memory performance of the Radeon R9 M275 is slightly better than the GT 445M.

The GeForce GT 445M v2 has 144 Shader Processing Units and the Radeon R9 M275 has 640. However, the actual shader performance of the GT 445M is 164 and the actual shader performance of the Radeon R9 M275 is 0. The GT 445M having 164 better shader performance is not particularly notable, as altogether the Radeon R9 M275 performs better when taking into account other relevant data.

The Radeon R9 M275 transistor size technology is 12 nm (nanometers) smaller than the GT 445M. This means that the Radeon R9 M275 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 R9 M275 requires 50 Watts. The Radeon R9 M275 requires 15 Watts more than the GT 445M to run. The difference is not significant enough for the Radeon R9 M275 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.
Radeon R9 M275 is a fast-middle-class-level graphics card based on the second revision of the Graphics Core Next architecture.
It offers a core codenamed Venus XT that packs 640 Shader Processing Units, 40 TMUs and 16 ROPs, on a 128-bit memory interface of fast GDDR5. While the central unit runs at XXXMHz and goes up to XXXMHz, in Turbo Mode, the memory clock operates at 1000MHz. The regular version should offer 2GB of video memory but expect to see gimmicks of up to 4GB.
Its performance is still unknown so use this rank as a guideline only.
