GeForce GT 230 vs Radeon R7 250X

Intro

The GeForce GT 230 features a clock speed of 550 MHz and a DDR3 memory speed of 800 MHz. It also features a 192-bit bus, and uses a 40 nm design. It features 32 SPUs, 16 TAUs, and 8 ROPs.

Compare all that to the Radeon R7 250X, which features a GPU core clock speed of 1000 MHz, and 1024 MB of GDDR5 memory set to run at 1125 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 TAUs, and 16 ROPs.

The Radeon R7 250X is a lot (more or less 355%) more effective at AF than the GeForce GT 230. (explain)

Radeon R7 250X 40000 Mtexels/sec
GeForce GT 230 8800 Mtexels/sec
Difference: 31200 (355%)

Pixel Rate

The Radeon R7 250X will be a lot (approximately 264%) faster with regards to anti-aliasing than the GeForce GT 230, and also should be able to handle higher resolutions while still performing well. (explain)

Radeon R7 250X 16000 Mpixels/sec
GeForce GT 230 4400 Mpixels/sec
Difference: 11600 (264%)

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 max amount of information (counted in MB per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If 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 amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
