GeForce GT 230 vs Radeon R9 M280X

Intro

The GeForce GT 230 makes use of a 40 nm design. nVidia has set the core speed at 550 MHz. The DDR3 memory works at a speed of 800 MHz on this model. It features 32 SPUs along with 16 Texture Address Units and 8 Rasterization Operator Units.

Compare those specs to the Radeon R9 M280X, which makes use of a 28 nm design. AMD has set the core speed at 900 MHz. The GDDR5 memory runs at a frequency of 1375 MHz on this particular model. It features 896 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.

GeForce GT 230 38400 MB/sec
Difference: 49600 (129%)

Texel Rate

The Radeon R9 M280X should be quite a bit (about 473%) faster with regards to texture filtering than the GeForce GT 230. (explain)

Radeon R9 M280X 50400 Mtexels/sec
GeForce GT 230 8800 Mtexels/sec
Difference: 41600 (473%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 M280X is the winner, and very much so. (explain)

Radeon R9 M280X 14400 Mpixels/sec
GeForce GT 230 4400 Mpixels/sec
Difference: 10000 (227%)

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 moved past the external memory interface in a second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

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