In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 675M SLI are massively better than the AMD Radeon R7 M265.

The Radeon R7 M265 has a 180 MHz higher core clock speed than the GTX 675M, but the GTX 675M has 104 more Texture Mapping Units than the Radeon R7 M265. As a result, the GTX 675M exhibits a 60.2 GTexel/s better Texture Fill Rate than the Radeon R7 M265. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The Radeon R7 M265 has a 180 MHz higher core clock speed than the GTX 675M, but the GTX 675M has 56 more Render Output Units than the Radeon R7 M265. As a result, the GTX 675M exhibits a 33.3 GPixel/s better Pixel Fill Rate than the Radeon R7 M265. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The Radeon R7 M265 was released over a year more recently than the GTX 675M, and so the Radeon R7 M265 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 Radeon R7 M265, 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 160 GB/sec greater memory bandwidth than the Radeon R7 M265, which means that the memory performance of the GTX 675M is massively better than the Radeon R7 M265.

The Radeon R7 M265 has 384 Shader Processing Units and the GeForce GTX 675M SLI has 768. However, the actual shader performance of the Radeon R7 M265 is 269 and the actual shader performance of the GTX 675M is 952. The GTX 675M having 683 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 Radeon R7 M265.

The Radeon R7 M265 transistor size technology is 12 nm (nanometers) smaller than the GTX 675M. This means that the Radeon R7 M265 is expected to run slightly cooler and achieve higher clock frequencies than the GTX 675M.

The Radeon R7 M265 requires 35 Watts to run and the GeForce GTX 675M SLI requires 200 Watts. The GTX 675M requires 165 Watts more than the Radeon R7 M265 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 Radeon R7 M265.

GPU Mini Review

Mini ReviewRadeon R7 M265 is a middle-class-level graphics card based on the second revision of the Graphics Core Next architecture.
It offers a core codenamed Marts XT that packs 384 Shader Processing Units, 24 TMUs and 8 ROPs, on a 128-bit memory interface of DDR3. While the central unit runs at 800MHz and goes up to 825MHz, in Turbo Mode, the memory clock operates at 1000MHz. The regular version should offer 2GB of video memory but expect to see gimmicks of up to 4GB.
Technically R7 M265 is just a higher-clocked Radeon HD 8750M and thus it should be able to run all of 2014's games at medium or high settings, using a 720p resolution.
This card should be paired with a decent Dual Core Processor at least 8GB of RAM.
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.
