GeForce GTX 465 vs Radeon R7 M260

Intro

Compare those specs to the Radeon R7 M260, which makes use of 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 specific card. It features 384 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce GTX 465 should in theory be much superior to the Radeon R7 M260 overall. (explain)

GeForce GTX 465		102592 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 86592 (541%)

Texel Rate

The GeForce GTX 465 will be much (more or less 56%) more effective at texture filtering than the Radeon R7 M260. (explain)

GeForce GTX 465		26708 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 9548 (56%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 465 is a better choice, and very much so. (explain)

GeForce GTX 465		19424 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 13704 (240%)

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 largest amount of information (measured in megabytes per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 are applied in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the graphics 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 amount of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
