GeForce GT 230 vs Radeon R7 250X

Intro

Compare all that to the Radeon R7 250X, which features clock speeds of 1000 MHz on the GPU, and 1125 MHz on the 1024 MB of GDDR5 memory. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 230		65 Watts
Radeon R7 250X		95 Watts
	Difference: 30 Watts (46%)

Memory Bandwidth

Theoretically, the Radeon R7 250X should perform quite a bit faster than the GeForce GT 230 overall. (explain)

Radeon R7 250X		72000 MB/sec
GeForce GT 230		38400 MB/sec
	Difference: 33600 (88%)

Texel Rate

The Radeon R7 250X will be quite a bit (about 355%) faster with regards to AF than the GeForce GT 230. (explain)

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

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R7 250X is a better choice, and very much so. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory per 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 - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends 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 reach the max fill rate.
