GeForce GTS 450 1GB vs Radeon R7 M260X

Intro

Compare those specifications to the Radeon R7 M260X, which comes with a core clock frequency of 825 MHz and a GDDR5 memory speed of 1000 MHz. It also uses a 128-bit memory bus, and makes use of a 28 nm design. It is comprised of 384 SPUs, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R7 M260X should theoretically be just a bit superior to the GeForce GTS 450 1GB overall. (explain)

Radeon R7 M260X		64000 MB/sec
GeForce GTS 450 1GB		57728 MB/sec
	Difference: 6272 (11%)

Texel Rate

The GeForce GTS 450 1GB will be quite a bit (about 27%) better at anisotropic filtering than the Radeon R7 M260X. (explain)

GeForce GTS 450 1GB		25056 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 5256 (27%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTS 450 1GB is the winner, by far. (explain)

GeForce GTS 450 1GB		12528 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 5928 (90%)

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 information (measured in MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
