GeForce GT 320 vs Radeon R7 240

Intro

Compare those specifications to the Radeon R7 240, which makes use of a 28 nm design. AMD has set the core speed at 730 MHz. The DDR3 RAM is set to run at a speed of 900 MHz on this particular card. It features 320 SPUs as well as 20 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 240		30 Watts
GeForce GT 320		43 Watts
	Difference: 13 Watts (43%)

Memory Bandwidth

Performance-wise, the Radeon R7 240 should theoretically be a little bit superior to the GeForce GT 320 in general. (explain)

Radeon R7 240		28800 MB/sec
GeForce GT 320		25280 MB/sec
	Difference: 3520 (14%)

Texel Rate

The Radeon R7 240 will be a bit (about 13%) better at texture filtering than the GeForce GT 320. (explain)

Radeon R7 240		14600 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 1640 (13%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R7 240 is a better choice, and very much so. (explain)

Radeon R7 240		5840 Mpixels/sec
GeForce GT 320		4320 Mpixels/sec
	Difference: 1520 (35%)

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: Bandwidth is the max amount of data (in units of megabytes per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units of the card 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units 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 rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
