In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 830M 2GB are very slightly better than the Nvidia GeForce GT 445M v2.

The GeForce 830M 2GB has a 512 MHz higher core clock speed but 8 fewer Texture Mapping Units than the GT 445M. The lower TMU count doesn't matter, though, as altogether the GeForce 830M 2GB manages to provide 3.6 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 GeForce 830M 2GB has a 512 MHz higher core clock speed than the GT 445M, but the GT 445M has 8 more Render Output Units than the GeForce 830M 2GB. As a result, the GT 445M exhibits a 0.4 GPixel/s better Pixel Fill Rate than the GeForce 830M 2GB. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GeForce 830M 2GB was released over three years more recently than the GT 445M, and so the GeForce 830M 2GB 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 GeForce 830M 2GB has 1024 MB more video memory than the GT 445M, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the GT 445M has superior memory performance.

The GT 445M has 25.6 GB/sec greater memory bandwidth than the GeForce 830M 2GB, which means that the memory performance of the GT 445M is slightly better than the GeForce 830M 2GB.

The GeForce GT 445M v2 has 144 Shader Processing Units and the GeForce 830M 2GB has 256. However, the actual shader performance of the GT 445M is 164 and the actual shader performance of the GeForce 830M 2GB is 397. The GeForce 830M 2GB having 233 better shader performance is not particularly notable, as altogether the GT 445M performs better when taking into account other relevant data.

The GeForce 830M 2GB transistor size technology is 12 nm (nanometers) smaller than the GT 445M. This means that the GeForce 830M 2GB is expected to run slightly cooler and achieve higher clock frequencies than the GT 445M. While they exhibit similar graphical performance, the GeForce 830M 2GB should consume less power than the GT 445M.

The GeForce GT 445M v2 requires 35 Watts to run and the GeForce 830M 2GB requires 25 Watts. The GT 445M requires 10 Watts more than the GeForce 830M 2GB 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 GeForce 830M 2GB.

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.
Overview
GeForce 830M 2GB is a Middle-Class Mobile Graphics Card based on the First Revision of the Maxwell architecture.

Architecture
The Maxwell architecture features many improvements and among them is the extremely large L2 Cache which allows NVIDIA to produce Graphics Cards with relatively small memory data transfer rates, without causing too much impact on the overall performance. Furthermore, the Shaders have been redesigned and are both more powerful and energy efficient.

GPU
It equips a GPU codenamed GM108 which has 2 SM activated and thus offers 256 Shader Processing Units, 16 TMUs and 8 ROPs. The central unit runs at 1082MHz and goes up to 1150MHz, in Turbo Mode.

Memory
The GPU accesses a 2GB frame buffer of DDR3, through a 64-bit memory interface. The Frame Buffer is exaggerated and in no way benefits the GPU. The memory clock operates at 900MHz.

Features
DirectX 11.2 Support (11.0 Hardware Default) and support for GPU Boost 2.0, GeForce Experience, PhysX and other technologies.

Power Consumption
With a rated board TDP of 25W, it will only be equipped in average sized notebooks.

Performance
Benchmarks indicate its performance is over 20% faster than the older GeForce GT 730M. Therefore, it should match GeForce GT 740M.

System Suggestions
We recommend a modest processor (Intel Core i5 Mobile) and 4GB of RAM for a notebook with GeForce 830M 2GB.
