GeForce GTX 260 vs Radeon R7 240

Intro

Compare those specs to the Radeon R7 240, which makes use of a 28 nm design. AMD has set the core speed at 730 MHz. The DDR3 memory runs at a speed of 900 MHz on this specific card. It features 320 SPUs as well as 20 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 240		30 Watts
GeForce GTX 260		182 Watts
	Difference: 152 Watts (507%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 260 should be 289% faster than the Radeon R7 240 in general, due to its greater bandwidth. (explain)

GeForce GTX 260		111888 MB/sec
Radeon R7 240		28800 MB/sec
	Difference: 83088 (289%)

Texel Rate

The GeForce GTX 260 should be quite a bit (more or less 152%) better at texture filtering than the Radeon R7 240. (explain)

GeForce GTX 260		36864 Mtexels/sec
Radeon R7 240		14600 Mtexels/sec
	Difference: 22264 (152%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 260 is superior to the Radeon R7 240, by far. (explain)

GeForce GTX 260		16128 Mpixels/sec
Radeon R7 240		5840 Mpixels/sec
	Difference: 10288 (176%)

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 megabytes per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video 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 could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
