GeForce GT 130 vs Radeon R7 240

Intro

Compare all of that to the Radeon R7 240, which has a core clock frequency of 730 MHz and a DDR3 memory frequency of 900 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It is made up of 320 SPUs, 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 130		75 Watts
	Difference: 45 Watts (150%)

Memory Bandwidth

The Radeon R7 240 should theoretically be a lot faster than the GeForce GT 130 in general. (explain)

Radeon R7 240		28800 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 16800 (140%)

Texel Rate

The Radeon R7 240 is much (more or less 22%) faster with regards to anisotropic filtering than the GeForce GT 130. (explain)

Radeon R7 240		14600 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 2600 (22%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GT 130 is the winner, and very much so. (explain)

GeForce GT 130		8000 Mpixels/sec
Radeon R7 240		5840 Mpixels/sec
	Difference: 2160 (37%)

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 moved past the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
