GeForce GTX 560 Ti 448 vs Radeon R9 M265X

Intro

Compare that to the Radeon R9 M265X, which features a core clock speed of 575 MHz and a GDDR5 memory speed of 1125 MHz. It also features a 128-bit bus, and makes use of a 28 nm design. It is made up of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTX 560 Ti 448 should theoretically be quite a bit better than the Radeon R9 M265X in general. (explain)

GeForce GTX 560 Ti 448		144000 MB/sec
Radeon R9 M265X		72000 MB/sec
	Difference: 72000 (100%)

Texel Rate

The GeForce GTX 560 Ti 448 is quite a bit (more or less 78%) faster with regards to texture filtering than the Radeon R9 M265X. (explain)

GeForce GTX 560 Ti 448		40992 Mtexels/sec
Radeon R9 M265X		23000 Mtexels/sec
	Difference: 17992 (78%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 560 Ti 448 is superior to the Radeon R9 M265X, and very much so. (explain)

GeForce GTX 560 Ti 448		29280 Mpixels/sec
Radeon R9 M265X		9200 Mpixels/sec
	Difference: 20080 (218%)

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 maximum amount of data (measured in megabytes per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that 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 - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
