GeForce GT 230 vs Radeon HD 7750

Intro

The GeForce GT 230 features core speeds of 550 MHz on the GPU, and 800 MHz on the 1536 MB of DDR3 RAM. It features 32 SPUs along with 16 TAUs and 8 ROPs.

Compare those specifications to the Radeon HD 7750, which comes with a core clock speed of 800 MHz and a GDDR5 memory frequency of 1125 MHz. It also features a 128-bit bus, and makes use of a 28 nm design. It features 512 SPUs, 32 Texture Address Units, and 16 ROPs.

The Radeon HD 7750 should in theory perform a lot faster than the GeForce GT 230 in general. (explain)

Radeon HD 7750 72000 MB/sec
GeForce GT 230 38400 MB/sec
Difference: 33600 (88%)

Texel Rate

The Radeon HD 7750 should be quite a bit (more or less 191%) faster with regards to AF than the GeForce GT 230. (explain)

Radeon HD 7750 25600 Mtexels/sec
GeForce GT 230 8800 Mtexels/sec
Difference: 16800 (191%)

Pixel Rate

The Radeon HD 7750 should be quite a bit (approximately 191%) more effective at FSAA than the GeForce GT 230, and should be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon HD 7750 12800 Mpixels/sec
GeForce GT 230 4400 Mpixels/sec
Difference: 8400 (191%)

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 MB per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the 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 amount of pixels 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 ROPs by the the core 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 output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
