GeForce GT 430 vs Radeon R9 380X

Intro

Compare all of that to the Radeon R9 380X, which makes use of a 28 nm design. AMD has set the core frequency at 970 MHz. The GDDR5 memory runs at a speed of 1425 MHz on this specific card. It features 2048 SPUs as well as 128 TAUs and 32 ROPs.

GeForce GT 430		11200 Mtexels/sec
	Difference: 112960 (1009%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 380X is superior to the GeForce GT 430, by a large margin. (explain)

Radeon R9 380X		31040 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 28240 (1009%)

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 largest amount of information (in units of megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster 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 in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
