GeForce GT 320 vs Radeon R7 240

Intro

Compare that to the Radeon R7 240, which uses a 28 nm design. AMD has set the core frequency at 730 MHz. The DDR3 RAM works at a speed of 900 MHz on this particular card. It features 320 SPUs as well as 20 TAUs and 8 Rasterization Operator Units.

The Radeon R7 240 should be a bit (approximately 13%) more effective 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

The Radeon R7 240 will be a lot (approximately 35%) more effective at FSAA than the GeForce GT 320, and also will be capable of handling higher resolutions while still performing well. (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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 processed per second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
