In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 M375X 4GB are significantly better than the Nvidia GeForce GT 445M v2.

The R9 M375X has a 330 MHz higher core clock speed and 16 more Texture Mapping Units than the GT 445M. This results in the R9 M375X providing 22.3 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 R9 M375X has a 330 MHz higher core clock speed than the GT 445M and the same number of Render Output Units. This results in the R9 M375X providing 5.3 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 R9 M375X was released over three years more recently than the GT 445M, and so the R9 M375X 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 R9 M375X has 3072 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 R9 M375X also has superior memory performance overall.

The R9 M375X has 32 GB/sec greater memory bandwidth than the GT 445M, which means that the memory performance of the R9 M375X is noticeably better than the GT 445M.

The Radeon R9 M375X 4GB has 640 Shader Processing Units and the GeForce GT 445M v2 has 144. However, the actual shader performance of the R9 M375X is 503 and the actual shader performance of the GT 445M is 164. The R9 M375X having 339 better shader performance and an altogether better performance when taking into account other relevant data means that the R9 M375X delivers a significantly smoother and more efficient experience when processing graphical data than the GT 445M.

The R9 M375X transistor size technology is 12 nm (nanometers) smaller than the GT 445M. This means that the R9 M375X is expected to run slightly cooler and achieve higher clock frequencies than the GT 445M.

The Radeon R9 M375X 4GB requires 75 Watts to run and the GeForce GT 445M v2 requires 35 Watts. The R9 M375X requires 40 Watts more than the GT 445M to run. The difference is significant enough that the R9 M375X may have a slight adverse affect on your yearly electricity bills in comparison to the GT 445M.

GPU Mini Review

Mini ReviewOverview
Radeon R9 M375X 4GB is a Performance Mobile Graphics Card based on the First Generation of the Graphics Core Next Architecture (GCN).

Radeon R9 M375X 4GB Features a GPU Codenamed Venus XTX which is a First Gen GCN GPU and is identical to the Cape GPU used on the Desktop Radeon R7 250X.
Venus XTX has 10 Compute Units Unlocked and thus offers 640 Shader Processing Units, 40 TMUs and 16 ROPs.

The Central Unit is Clocked at 900MHz and goes up to 925MHz, in Turbo Mode.

Memory: Speed
The GPU is equipped with fast GDDR5 and Accesses the Frame Buffer through a 128-bit Memory Interface. The Memory Clock Operates at 1125MHz.

Memory: Frame Buffer
The GPU can fill up a Memory Pool of up to 4GB. Under most circumstances, this only proves useful in certain 3D Games whose Settings Require Large Amounts of Memory.
However, because the GPU itself is too weak to work under other circumstances in which 4GB of Memory are needed - such as 4K Gaming, a Large Frame Buffer is mostly a Gimmick.

Power Consumption
With a rated board TDP of 75W, it is suited for large laptops.

Radeon R9 M375X 4GB is a Direct Rebrand of Radeon R9 M275X.
Performance is Comparable to the Desktop Radeon R7 250X.

System Suggestions
Radeon R9 M375X 4GB is best suited for resolutions up to and including 1600x900. We recommend a Strong Processor and 8GB of RAM for Optimal Performance.
GeForce GT 445M v2 is a Fast-Middle-Class Mobile Graphics Card based on the first revision of the Fermi 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.

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.

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.

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.

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.
