GeForce GT 430 1GB vs Radeon HD 6570 (OEM) 1GB

Intro

The GeForce GT 430 1GB comes with core speeds of 700 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR3 RAM. It features 96 SPUs as well as 16 Texture Address Units and 4 Rasterization Operator Units.

Compare all that to the Radeon HD 6570 (OEM) 1GB, which has core clock speeds of 650 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR3 memory. It features 480 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 6570 (OEM) 1GB 50 Watts
GeForce GT 430 1GB 60 Watts
Difference: 10 Watts (20%)

Memory Bandwidth

Both cards have the exact same bandwidth, so theoretically they should perform exactly the same. (explain)

Texel Rate

The Radeon HD 6570 (OEM) 1GB should be much (approximately 39%) faster with regards to anisotropic filtering than the GeForce GT 430 1GB. (explain)

Radeon HD 6570 (OEM) 1GB 15600 Mtexels/sec
GeForce GT 430 1GB 11200 Mtexels/sec
Difference: 4400 (39%)

Pixel Rate

The Radeon HD 6570 (OEM) 1GB is a lot (more or less 86%) better at AA than the GeForce GT 430 1GB, and also will be capable of handling higher resolutions without slowing down too much. (explain)

Radeon HD 6570 (OEM) 1GB 5200 Mpixels/sec
GeForce GT 430 1GB 2800 Mpixels/sec
Difference: 2400 (86%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.

hmmm. looks like ATI is way infront of the GeForce. Even though I have always wanted GeForce cause it SEEMS better. Looks like ATI has won my money. As much as I would like to have the nVidia card I want the better card so ATI is my choice
