GeForce GT 430 vs Radeon R9 M275X

Intro

The GeForce GT 430 makes use of a 40 nm design. nVidia has set the core speed at 700 MHz. The GDDR3 RAM works at a speed of 900 MHz on this specific model. It features 96 SPUs as well as 16 Texture Address Units and 4 Rasterization Operator Units.

Compare those specifications to the Radeon R9 M275X, which makes use of a 28 nm design. AMD has set the core frequency at 900 MHz. The GDDR5 RAM runs at a speed of 1125 MHz on this specific card. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

GeForce GT 430 28800 MB/sec
Difference: 43200 (150%)

Texel Rate

The Radeon R9 M275X should be quite a bit (about 221%) faster with regards to texture filtering than the GeForce GT 430. (explain)

Radeon R9 M275X 36000 Mtexels/sec
GeForce GT 430 11200 Mtexels/sec
Difference: 24800 (221%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M275X is a better choice, by a large margin. (explain)

Radeon R9 M275X 14400 Mpixels/sec
GeForce GT 430 2800 Mpixels/sec
Difference: 11600 (414%)

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 information (measured in MB per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics 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 maximum amount of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
