Gaming Performance Comparison

In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 6570 2GB DDR3 are marginally better than the Nvidia GeForce GT 630 GDDR5.

The GT 630 has a 160 MHz higher core clock speed than the HD 6570, but the HD 6570 has 8 more Texture Mapping Units than the GT 630. As a result, the HD 6570 exhibits a 2.6 GTexel/s better Texture Fill Rate than the GT 630. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GT 630 has a 160 MHz higher core clock speed than the HD 6570, but the HD 6570 has 4 more Render Output Units than the GT 630. As a result, the HD 6570 exhibits a 2 GPixel/s better Pixel Fill Rate than the GT 630. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GT 630 was released over a year more recently than the HD 6570, and so the GT 630 is likely to have better driver support, meaning it will be more optimized for running the latest games.

The HD 6570 has 1024 MB more video memory than the GT 630, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The GT 630 has 22.4 GB/sec greater memory bandwidth than the HD 6570, which means that the memory performance of the GT 630 is slightly better than the HD 6570.

The GeForce GT 630 GDDR5 has 96 Shader Processing Units and the Radeon HD 6570 2GB DDR3 has 480. However, the actual shader performance of the GT 630 is 156 and the actual shader performance of the HD 6570 is 203. The HD 6570 having 47 better shader performance is not particularly notable, as altogether the GT 630 performs better when taking into account other relevant data.

The GeForce GT 630 GDDR5 requires 65 Watts to run and the Radeon HD 6570 2GB DDR3 requires 60 Watts. We would recommend a PSU with at least 300 Watts for the GT 630 and a PSU with at least 400 Watts for the HD 6570. The GT 630 requires 5 Watts more than the HD 6570 to run. The difference is not significant enough for the GT 630 to have a noticeably larger impact on your yearly electricity bills than the HD 6570.

GPU Mini Review

Mini ReviewGeForce 630 1GB GDDR5 is a middle-class graphics card still based on the 2010, 40nm, Fermi architecture.
It's based on the 'Fermi GF108' Core and offers 96 Shader Processing Units, 16 TMUs and 4 ROPs, on 128-bit memory interface of fast GDDR5. The central unit runs at 810MHz and the memory clock operates at 800MHz.
Compared to the reference DDR3 Card, it should offer exactly the same performance at lower resolutions. Despite being equipped with fast GDDR5, this Graphics Card will not perform very well at anything higher than 1440x900.
This Graphics Card can be paired with any average Dual-Core CPU.
Radeon HD 6570 2GB 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 2GB DDR3 version which will perform EXACTLY like the 1GB DDR3 version due to the GPU limitations and therefore considered a gimmick.
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.
