In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R7 M270 are very slightly better than the Nvidia GeForce GT 445M v2.

The Radeon R7 M270 has a 155 MHz higher core clock speed and the same number of Texture Mapping Units as the GT 445M. This results in the Radeon R7 M270 providing 3.7 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 R7 M270 has a 155 MHz higher core clock speed than the GT 445M, but the GT 445M has 8 more Render Output Units than the Radeon R7 M270. As a result, the GT 445M exhibits a 3.3 GPixel/s better Pixel Fill Rate than the Radeon R7 M270. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The Radeon R7 M270 was released over three years more recently than the GT 445M, and so the Radeon R7 M270 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 R7 M270 has 3072 MB more video memory than the GT 445M, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The GT 445M has 8 GB/sec greater memory bandwidth than the Radeon R7 M270, which means that the memory performance of the GT 445M is marginally better than the Radeon R7 M270.

The Radeon R7 M270 has 384 Shader Processing Units and the GeForce GT 445M v2 has 144. However, the actual shader performance of the Radeon R7 M270 is 269 and the actual shader performance of the GT 445M is 164. The Radeon R7 M270 having 105 better shader performance is not particularly notable, as altogether the GT 445M performs better when taking into account other relevant data.

The Radeon R7 M270 transistor size technology is 12 nm (nanometers) smaller than the GT 445M. This means that the Radeon R7 M270 is expected to run slightly cooler and achieve higher clock frequencies than the GT 445M. While they exhibit similar graphical performance, the Radeon R7 M270 should consume less power than the GT 445M.

The Radeon R7 M270 requires 30 Watts to run and the GeForce GT 445M v2 requires 35 Watts. The GT 445M requires 5 Watts more than the Radeon R7 M270 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 Radeon R7 M270.

GPU Mini Review

Mini ReviewOverview
Radeon R7 M270 is a Middle-Class Mobile Graphics Card based on the First Revision of the Graphics Core Next (GCN) Architecture.

Architecture
The GCN 1.1 revision of the Graphics Core Next Architecture adds new important technologies and is largely oriented for energy efficiency. New technologies such as PowerTune and TrueAudio are the biggest additions as well as DirectX 11.2 support.

GPU
It equips a GPU Codenamed Opal XT which has 6 Compute Units activated and thus offers 384 Shader Processing Units, 24 TMUs and 8 ROPs. The Central Unit is clocked at 725MHz and goes up to 825MHz, in Turbo Mode.

Memory
The GPU accesses a 4GB 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.

Performance
Radeon R7 M270 should be as fast as Radeon R7 M265 and thus offer Performance similar to GeForce GT 740M.

System Suggestions
Radeon R7 M270 is best suited for resolutions up to and including 1366x768. We recommend a Modest Processor and 4GB of RAM for Optimal Performance.
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.
