Gaming Performance Comparison

In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 675MX are massively better than the AMD Radeon HD 7570M 1GB GDDR5.

The GeForce GTX 675MX and the HD 7570M have the same core clock speed of 600 MHz, but the GeForce GTX 675MX has 56 more Texture Mapping Units than the HD 7570M. As a result, the GeForce GTX 675MX exhibits a 33.6 GTexel/s better Texture Fill Rate than the HD 7570M. 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 and the HD 7570M have the same core clock speed of 600 MHz, but the GeForce GTX 675MX has 24 more Render Output Units than the HD 7570M. As a result, the GeForce GTX 675MX exhibits a 14.4 GPixel/s better Pixel Fill Rate than the HD 7570M. 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 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 3072 MB more video memory than the 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 86.4 GB/sec greater memory bandwidth than the HD 7570M, which means that the memory performance of the GeForce GTX 675MX is much better than the HD 7570M.

The GeForce GTX 675MX has 960 Shader Processing Units and the Radeon HD 7570M 1GB GDDR5 has 400. However, the actual shader performance of the GeForce GTX 675MX is 576 and the actual shader performance of the HD 7570M is 132. The GeForce GTX 675MX having 444 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 HD 7570M.

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

The GeForce GTX 675MX requires 100 Watts to run but there is no entry for the Radeon HD 7570M 1GB GDDR5.

GPU Mini Review

Mini ReviewNote: If you have an iMac, please select GeForce GTX 675MX Mac Edition as your card.

GeForce GTX 675MX is a high-end mobile GFX based on the 2012 Kepler architecture.

It's based on the Kepler GK104 Core and thus offers 960 Shader Processing Units activated, 80 TMUs and 32 ROPs on a 256-bit memory interface of up to 4GB GDDR5. The central clock runs at 600MHz and the memory clock operates at 900MHz. Expect a power consumption of up to 100 Watts.

Expect modern demanding games to be playable at 1080p with very fluent frame rates (45+).
Radeon HD 7570M 1GB GDDR5, codenamed 'Thames-XT', is a mid-range GPU part of the Mobility HD 7000M Series released by AMD in 2012.
It's still based on the old Turks chip and therefore a renamed Radeon HD 6650M but only 400 of the 480 Pipelines are available. The core-clock will range from 450MHz to 650MHz, and will be decided by the laptop manufacturer, probably according to the cooling system and the memory clock, with fast GDDR5 will be set to 900MHz. Using fast GDDR5, its performance will be very similar to the Radeon HD 6550M, since it's paired with a 64 bits bus.
A DDR3 version, codenamed "Thames-PRO" is also manufactured.
The performance is very limited and so Very Demanding games (e.g. Metro 2033, Max Payne 3) will only run on the lowest settings and even Demanding games (e.g. Crysis, Mafia 2) might require very reduced settings.
