In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 675MX are massively better than the AMD Radeon HD 7570M.

The GeForce GTX 675MX has a 100 MHz higher core clock speed and 56 more Texture Mapping Units than the Radeon HD 7570M. This results in the GeForce GTX 675MX providing 36 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 GTX 675MX has a 100 MHz higher core clock speed and 24 more Render Output Units than the Radeon HD 7570M. This results in the GeForce GTX 675MX providing 15.2 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 GeForce GTX 675MX was released less than a year after the Radeon HD 7570M, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GeForce GTX 675MX has 1024 MB more video memory than the Radeon HD 7570M, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GeForce GTX 675MX also has superior memory performance overall.

The GeForce GTX 675MX has 89.6 GB/sec greater memory bandwidth than the Radeon HD 7570M, which means that the memory performance of the GeForce GTX 675MX is much better than the Radeon HD 7570M.

The GeForce GTX 675MX has 960 Shader Processing Units and the Radeon HD 7570M has 480. However, the actual shader performance of the GeForce GTX 675MX is 576 and the actual shader performance of the Radeon HD 7570M is 120. The GeForce GTX 675MX having 456 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GTX 675MX delivers a massively smoother and more efficient experience when processing graphical data than the Radeon HD 7570M.

The GeForce GTX 675MX transistor size technology is 12 nm (nanometers) smaller than the Radeon HD 7570M. This means that the GeForce GTX 675MX is expected to run slightly cooler and achieve higher clock frequencies than the Radeon HD 7570M.

The GeForce GTX 675MX requires 100 Watts to run and the Radeon HD 7570M requires 13 Watts. The GeForce GTX 675MX requires 87 Watts more than the Radeon HD 7570M to run. The difference is significant enough that the GeForce GTX 675MX may have an adverse affect on your yearly electricity bills in comparison to the Radeon HD 7570M.

GPU Mini Review

Mini ReviewOverview
GeForce GTX 675MX is a High-End Mobile Graphics Card based on the first revision of the Kepler Architecture.

Architecture
The Kepler Architecture was NVIDIA's big step to power efficiency. Each Stream Multiprocessor (SMX) now hosts 192 Shader Processing Units - against the 48 of older Fermi Architecture, and has been redesigned being now clocked at the same speed of the Central Unit. This means they are more energy efficient and will consequently lead to cooler operating temperatures. However, it also means they are weaker. It can be said that one Fermi SMX is as fast as 2 Kepler SMXs.
Additionally, and not available in all GPUs, Kepler also introduced the Boost Clock Feature. The Boost Clock is an even higher Clock Speed activated when in gaming mode and becomes the effective speed of the GPU.

GPU
It equips a GPU Codenamed Kepler GK104-N13E-GSR-A2 which has 5 Stream Multiprocessors activated and thus offers 960 Shader Processing Units, 80 TMUs and 32 ROPs. The Central Unit is clocked at 600MHz.

Memory
The GPU accesses a 2GB frame buffer of fast GDDR5, through a 256-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 900MHz.

Features
DirectX 11.0 Support (11.0 Hardware Default) and support for SLI, Optimus, CUDA, OpenCL, DirectCompute, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies

Power Consumption
With a rated board TDP of 100W, it is suited for very large sized laptops.

Performance
Gaming benchmarks indicate is not too far from the desktop GeForce GTX 650 Ti Boost Edition.

System Suggestions
We recommend a Power Processor (Intel Core i7 Mobile) and 8GB of RAM for a system with GeForce GTX 675MX.
Overview
Radeon HD 7570M is an Entry-Level Mobile Graphics Card based on the second revision of the Terascale Architecture.

Architecture
The Second variant of the Terascale 2 Architecture is still manufactured with a 40nm technology and despite allowing more Stream Cores, their design remains more or less the same compared to the first variant.

GPU
It equips a GPU codenamed Thames PRO which has 6 Compute Units activated and thus offers 480 Shader Processing Units, 24 TMUs and 8 ROPs. The Central Unit runs at 500MHz.

Memory
The GPU accesses a 1GB frame buffer of fast GDDR5, through a 64-bit memory interface. The size of the frame buffer is adequate. The memory clock operates at 800MHz.

Features
DirectX 11.0 Support (11.0 Hardware Default) and support for Crossfire, HD3D, Eyefinity, App Acceleration, PowerPlay and other technologies.

Power Consumption
With a rated board TDP of 13W, it is suited for average sized laptops.

Performance
Gaming benchmarks put its performance somewhere on average with GeForce GT 525M.

System Suggestions
We recommend a Modest Processor (Intel Core i3 Mobile and 4GB of RAM for a system with Radeon HD 7570M.
