In terms of overall gaming performance, the graphical capabilities of the Nvidia Quadro K4000M are significantly better than the Nvidia GeForce GT 445M v2.

The Quadro K4000M has a 31 MHz higher core clock speed and 56 more Texture Mapping Units than the GT 445M. This results in the Quadro K4000M providing 34.4 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 Quadro K4000M has a 31 MHz higher core clock speed and 16 more Render Output Units than the GT 445M. This results in the Quadro K4000M providing 10.1 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 Quadro K4000M was released over a year more recently than the GT 445M, and so the Quadro K4000M 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 Quadro K4000M 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 Quadro K4000M also has superior memory performance overall.

The Quadro K4000M has 49.6 GB/sec greater memory bandwidth than the GT 445M, which means that the memory performance of the Quadro K4000M is noticeably better than the GT 445M.

The GeForce GT 445M v2 has 144 Shader Processing Units and the Quadro K4000M has 960. However, the actual shader performance of the GT 445M is 164 and the actual shader performance of the Quadro K4000M is 577. The Quadro K4000M having 413 better shader performance and an altogether better performance when taking into account other relevant data means that the Quadro K4000M delivers a significantly smoother and more efficient experience when processing graphical data than the GT 445M.

The Quadro K4000M transistor size technology is 12 nm (nanometers) smaller than the GT 445M. This means that the Quadro K4000M 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 Quadro K4000M requires 100 Watts. The Quadro K4000M requires 65 Watts more than the GT 445M to run. The difference is significant enough that the Quadro K4000M may have an adverse affect on your yearly electricity bills in comparison to 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.
Quadro K4000M is a high-end business card based on the 28nm, Kepler architecture.
Technically the successor to the previous Quadro 4000M, it's based on the Kepler GK104 (despite the SPU count) and offers 960 Shader Processing Units, 80 TMUs and 32 ROPs, on a 256-bit memory interface of fast GDDR5. The central unit runs at 600MHz and the memory clock operates at up to 700MHz.
Quadro K4000M's drivers are certified for professional applications. Therefore, and also because it's underclocked, its performance lies closer to GeForce GTX 675M despite the similarities to GeForce GTX 675MX.
