GeForce GT 430 1GB vs Radeon R7 240

Intro

Compare all that to the Radeon R7 240, which features 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 SPUs, 20 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 240		30 Watts
GeForce GT 430 1GB		60 Watts
	Difference: 30 Watts (100%)

Memory Bandwidth

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

Texel Rate

The Radeon R7 240 should be a lot (more or less 30%) more effective at anisotropic filtering than the GeForce GT 430 1GB. (explain)

Radeon R7 240		14600 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 3400 (30%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R7 240 is superior to the GeForce GT 430 1GB, by far. (explain)

Radeon R7 240		5840 Mpixels/sec
GeForce GT 430 1GB		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 moved past the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at 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 the video card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). 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 max fill rate.
