In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 675M SLI are massively better than the Nvidia GeForce 830M 2GB.

The GeForce 830M 2GB has a 462 MHz higher core clock speed than the GTX 675M, but the GTX 675M has 112 more Texture Mapping Units than the GeForce 830M 2GB. As a result, the GTX 675M exhibits a 62.1 GTexel/s better Texture Fill Rate than the GeForce 830M 2GB. 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 462 MHz higher core clock speed than the GTX 675M, but the GTX 675M has 56 more Render Output Units than the GeForce 830M 2GB. As a result, the GTX 675M exhibits a 31 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 a year more recently than the GTX 675M, and so the GeForce 830M 2GB is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 675M.

The GTX 675M has 2048 MB more video memory than the GeForce 830M 2GB, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 675M also has superior memory performance overall.

The GTX 675M has 177.6 GB/sec greater memory bandwidth than the GeForce 830M 2GB, which means that the memory performance of the GTX 675M is massively better than the GeForce 830M 2GB.

The GeForce 830M 2GB has 256 Shader Processing Units and the GeForce GTX 675M SLI has 768. However, the actual shader performance of the GeForce 830M 2GB is 397 and the actual shader performance of the GTX 675M is 952. The GTX 675M having 555 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 675M delivers a massively smoother and more efficient experience when processing graphical data than the GeForce 830M 2GB.

The GeForce 830M 2GB transistor size technology is 12 nm (nanometers) smaller than the GTX 675M. This means that the GeForce 830M 2GB is expected to run slightly cooler and achieve higher clock frequencies than the GTX 675M.

The GeForce 830M 2GB requires 25 Watts to run and the GeForce GTX 675M SLI requires 200 Watts. The GTX 675M requires 175 Watts more than the GeForce 830M 2GB to run. The difference is significant enough that the GTX 675M may have an adverse affect on your yearly electricity bills in comparison to the GeForce 830M 2GB.

GPU Mini Review

Mini ReviewOverview
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.
GeForce GTX 675M SLI is a solution of two GeForce GTX 675M put together using NVIDIA'S SLI technology.
Check the page of GeForce GTX 675M to know more about its chip.
As usual, SLI relies a lot on proper driver support and may suffer from micro-stuttering in lower frame rates (below 30). Benchmarks indicate the performance is overall, about 35% better than a single GeForce GTX 675M performing by itself but at times (depending whether or not the 3D game supports SLI or in the graphics driver) it performed worse than a single GeForce GTX 675M.
Even the most demanding games will run at the highest settings.
