GeForce GT 430 (OEM) vs Radeon R7 240

Intro

Compare all of that to the Radeon R7 240, which comes with a GPU core clock speed of 730 MHz, and 2048 MB of DDR3 RAM set to run at 900 MHz through a 128-bit bus. It also is made up of 320 Stream Processors, 20 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Both cards have the exact same memory bandwidth, so in theory they should have identical performance. (explain)

Texel Rate

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

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

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R7 240 is a better choice, by far. (explain)

Radeon R7 240		5840 Mpixels/sec
GeForce GT 430 (OEM)		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 largest amount of data (measured in megabytes per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

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