GeForce GT 130 vs Radeon R7 240

Intro

Compare all that to the Radeon R7 240, which has 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 features 320 SPUs, 20 Texture Address Units, and 8 ROPs.

Texel Rate

The Radeon R7 240 is much (about 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 running with a high screen resolution is important to you, then the GeForce GT 130 is the winner, by a large margin. (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 (in units of MB per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 processed in one second. This number is calculated by multiplying the total amount of texture units by the core clock 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 applied per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. 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 rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
