GeForce GT 320 vs Radeon R7 M260

Intro

Compare all that to the Radeon R7 M260, which uses a 28 nm design. AMD has set the core frequency at 715 MHz. The DDR3 RAM runs at a speed of 1000 MHz on this particular card. It features 384 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GT 320 should be quite a bit faster than the Radeon R7 M260 in general. (explain)

GeForce GT 320		25280 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 9280 (58%)

Texel Rate

The Radeon R7 M260 is much (about 32%) faster with regards to anisotropic filtering than the GeForce GT 320. (explain)

Radeon R7 M260		17160 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 4200 (32%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R7 M260 is superior to the GeForce GT 320, and very much so. (explain)

Radeon R7 M260		5720 Mpixels/sec
GeForce GT 320		4320 Mpixels/sec
	Difference: 1400 (32%)

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 transferred past the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the 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 maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
