GeForce GT 340 vs Radeon R7 M260X

Intro

The GeForce GT 340 has a core clock frequency of 550 MHz and a GDDR5 memory speed of 850 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It features 96 SPUs, 32 TAUs, and 8 ROPs.

Compare those specifications to the Radeon R7 M260X, which features a core clock frequency of 825 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of 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

The Radeon R7 M260X, in theory, should be a little bit faster than the GeForce GT 340 overall. (explain)

Radeon R7 M260X 64000 MB/sec
GeForce GT 340 54400 MB/sec
Difference: 9600 (18%)

Texel Rate

The Radeon R7 M260X will be just a bit (approximately 13%) better at texture filtering than the GeForce GT 340. (explain)

Radeon R7 M260X 19800 Mtexels/sec
GeForce GT 340 17600 Mtexels/sec
Difference: 2200 (13%)

Pixel Rate

The Radeon R7 M260X is a lot (more or less 50%) more effective at FSAA than the GeForce GT 340, and also will be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon R7 M260X 6600 Mpixels/sec
GeForce GT 340 4400 Mpixels/sec
Difference: 2200 (50%)

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.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
