Gaming Performance Comparison

In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 635 are noticeably better than the AMD Radeon HD 6570 1GB DDR3.

The GeForce GT 635 has a 317 MHz higher core clock speed than the HD 6570, but the HD 6570 has 8 more Texture Mapping Units than the GeForce GT 635. As a result, the HD 6570 exhibits a 0.1 GTexel/s better Texture Fill Rate than the GeForce GT 635. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GeForce GT 635 has a 317 MHz higher core clock speed than the HD 6570 and the same number of Render Output Units. This results in the GeForce GT 635 providing 2.5 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 GT 635 was released over a year more recently than the HD 6570, and so the GeForce GT 635 is likely to have better driver support, meaning it will be more optimized for running the latest games.

The GeForce GT 635 has 1024 MB more video memory than the HD 6570, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The HD 6570 has 12.8 GB/sec greater memory bandwidth than the GeForce GT 635, which means that the memory performance of the HD 6570 is slightly better than the GeForce GT 635.

The GeForce GT 635 has 384 Shader Processing Units and the Radeon HD 6570 1GB DDR3 has 480. However, the actual shader performance of the GeForce GT 635 is 371 and the actual shader performance of the HD 6570 is 203. The GeForce GT 635 having 168 better shader performance is not particularly notable, as altogether the HD 6570 performs better when taking into account other relevant data.

The GeForce GT 635 transistor size technology is 12 nm (nanometers) smaller than the HD 6570. This means that the GeForce GT 635 is expected to run slightly cooler and achieve higher clock frequencies than the HD 6570.

The GeForce GT 635 requires 35 Watts to run and the Radeon HD 6570 1GB DDR3 requires 44 Watts. We would recommend a PSU with at least 350 Watts for the GeForce GT 635 and a PSU with at least 400 Watts for the HD 6570. The HD 6570 requires 9 Watts more than the GeForce GT 635 to run. The difference is not significant enough for the HD 6570 to have a noticeably larger impact on your yearly electricity bills than the GeForce GT 635.

GPU Mini Review

Mini ReviewGeForce GT 635 (OEM) is an OEM upcoming middle-class Graphics Card based on the GK208 Core of the Kepler 2.0 architecture.
The Kepler GK208 Core is a power optimized Kepler GK108 Core that offers offers 384 Shader Processing Units, 16 TMUs and 8 ROPs, on a 64-bit memory interface of standard DDR3. While the central unit runs at 967MHz, the memory clock operates at 1002MHz.
Its performance is comparable to GeForce GT 640 and significantly faster than GeForce GT 630 at lower resolutions but performance is hindered by its very narrow bus-width.
Radeon HD 6570 1GB DDR3 is a middle-class GPU part of the Radeon HD 6000 Series released by AMD in 2010/2011.
There are many versions, whereas the only differences are the Memory Type (from DDR3 to GDDR5) and the amount of video memory (from 512MB to 2048MB). This is the 1GB DDR3 version.
The result is a solid middle-class GPU able to play Very Demanding games at low or Medium settings, depending on the resolution + DirectX version used. Demanding games should run fluently from medium to high settings.
