GeForce GT 430 (OEM) vs Radeon R7 250X

Intro

Compare those specs to the Radeon R7 250X, which comes with core speeds of 1000 MHz on the GPU, and 1125 MHz on the 1024 MB of GDDR5 memory. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

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

Texel Rate

The Radeon R7 250X should be much (more or less 257%) more effective at AF than the GeForce GT 430 (OEM). (explain)

Radeon R7 250X		40000 Mtexels/sec
GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 28800 (257%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R7 250X is the winner, by a large margin. (explain)

Radeon R7 250X		16000 Mpixels/sec
GeForce GT 430 (OEM)		2800 Mpixels/sec
	Difference: 13200 (471%)

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: Bandwidth is the max amount of data (in units of MB per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 amount of texture map elements (texels) that can be applied 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 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 number of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant 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.
