GeForce GT 320 vs Radeon R7 M260

Intro

Compare those specifications to the Radeon R7 M260, which uses a 28 nm design. AMD has clocked the core frequency at 715 MHz. The DDR3 memory is set to run at a frequency of 1000 MHz on this particular model. It features 384 SPUs as well as 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

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

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

Texel Rate

The Radeon R7 M260 should be a lot (more or less 32%) better at texture 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 resolution is important to you, then the Radeon R7 M260 is a better choice, 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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (in units of megabytes per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the 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 most pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
