GeForce GT 430 vs Radeon R7 260X

Intro

Compare all that to the Radeon R7 260X, which comes with GPU clock speed of 1100 MHz, and 2048 MB of GDDR5 memory running at 1625 MHz through a 128-bit bus. It also features 896 Stream Processors, 56 TAUs, and 16 ROPs.

GeForce GT 430		60 Watts
Radeon R7 260X		115 Watts
	Difference: 55 Watts (92%)

Memory Bandwidth

Performance-wise, the Radeon R7 260X should in theory be a lot superior to the GeForce GT 430 in general. (explain)

Radeon R7 260X		104000 MB/sec
GeForce GT 430		28800 MB/sec
	Difference: 75200 (261%)

Texel Rate

The Radeon R7 260X will be much (about 450%) more effective at AF than the GeForce GT 430. (explain)

Radeon R7 260X		61600 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 50400 (450%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R7 260X is a better choice, by far. (explain)

Radeon R7 260X		17600 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 14800 (529%)

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 (measured in MB per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 are processed per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write 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 clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel 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 potential to reach the max fill rate.
