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

Intro

The GeForce GT 430 1GB has a GPU core speed of 700 MHz, and the 1024 MB of GDDR3 memory is set to run at 900 MHz through a 128-bit bus. It also features 96 SPUs, 16 Texture Address Units, and 4 Raster Operation Units.

Compare those specifications to the Radeon HD 6570 (OEM) 1GB, which uses a 40 nm design. AMD has clocked the core speed at 650 MHz. The GDDR3 RAM works at a speed of 900 MHz on this particular model. It features 480 SPUs along with 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 exactly the same bandwidth, so in theory they should have identical performance. (explain)

Texel Rate

The Radeon HD 6570 (OEM) 1GB is much (about 39%) faster with regards to texture 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 should be quite a bit (more or less 86%) faster with regards to AA than the GeForce GT 430 1GB, and able to handle higher resolutions without losing too much performance. (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: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to 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
