GeForce GT 430 vs Radeon R7 240

Intro

Compare that to the Radeon R7 240, which features a core clock frequency of 730 MHz and a DDR3 memory frequency of 900 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It is comprised of 320 SPUs, 20 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 240		30 Watts
GeForce GT 430		60 Watts
	Difference: 30 Watts (100%)

Memory Bandwidth

Both cards have the exact same memory bandwidth, so theoretically they should perform exactly the same. (explain)

Texel Rate

The Radeon R7 240 is a lot (more or less 30%) faster with regards to texture filtering than the GeForce GT 430. (explain)

Radeon R7 240		14600 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 3400 (30%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R7 240 is superior to the GeForce GT 430, and very much so. (explain)

Radeon R7 240		5840 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 3040 (109%)

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 maximum amount of data (counted in MB per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's 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 number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
