In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 M290X Crossfire are significantly better than the Nvidia GeForce GTX 675M SLI.

The R9 M290X has a 230 MHz higher core clock speed and 32 more Texture Mapping Units than the GTX 675M. This results in the R9 M290X providing 56.6 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 R9 M290X has a 230 MHz higher core clock speed than the GTX 675M and the same number of Render Output Units. This results in the R9 M290X providing 14.7 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 M290X was released over a year more recently than the GTX 675M, and so the R9 M290X is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 675M.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The Radeon R9 M290X Crossfire and the GeForce GTX 675M SLI have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The R9 M290X has 115.2 GB/sec greater memory bandwidth than the GTX 675M, which means that the memory performance of the R9 M290X is massively better than the GTX 675M.

The Radeon R9 M290X Crossfire has 2560 Shader Processing Units and the GeForce GTX 675M SLI has 768. However, the actual shader performance of the R9 M290X is 1958 and the actual shader performance of the GTX 675M is 952. The R9 M290X having 1006 better shader performance and an altogether better performance when taking into account other relevant data means that the R9 M290X delivers a massively smoother and more efficient experience when processing graphical data than the GTX 675M.

The R9 M290X transistor size technology is 12 nm (nanometers) smaller than the GTX 675M. This means that the R9 M290X is expected to run slightly cooler and achieve higher clock frequencies than the GTX 675M.

The Radeon R9 M290X Crossfire requires 200 Watts to run and the GeForce GTX 675M SLI requires 200 Watts. The two GPUs require the same amount of wattage to run. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

GPU Mini Review

Mini ReviewRadeon R9 M290X Crossfire is a solution of two Radeon R9 M290X put together using AMD'S Crossfire technology.
Check the page of Radeon R9 M290X to know more about its chip.
Crossfire 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, is up to twice as better as a single Radeon R9 M290X performing by itself but at times (depending whether or not the 3D game supports crossfire or in the graphics driver) it performed worse than a single Radeon R9 M290X.
Even the most demanding games will run at the highest settings.
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.
