GeForce GT 130 vs Radeon R7 240

Intro

Compare those specs to the Radeon R7 240, which uses a 28 nm design. AMD has set the core frequency at 730 MHz. The DDR3 memory is set to run at a speed of 900 MHz on this card. It features 320 SPUs along with 20 Texture Address Units and 8 ROPs.

Radeon R7 240		30 Watts
GeForce GT 130		75 Watts
	Difference: 45 Watts (150%)

Memory Bandwidth

Theoretically speaking, the Radeon R7 240 is 140% faster than the GeForce GT 130 overall, due to its greater data rate. (explain)

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

Texel Rate

The Radeon R7 240 is a lot (approximately 22%) more effective at AF 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 resolution is important to you, then the GeForce GT 130 is a better choice, by far. (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 max amount of data (measured in MB per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the card's 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 bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
