GeForce GT 340 vs Radeon R7 M260X

Intro

The GeForce GT 340 has core clock speeds of 550 MHz on the GPU, and 850 MHz on the 512 MB of GDDR5 RAM. It features 96 SPUs along with 32 Texture Address Units and 8 Rasterization Operator Units.

Compare all that to the Radeon R7 M260X, which features a core clock frequency of 825 MHz and a GDDR5 memory frequency of 1000 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It is comprised of 384 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R7 M260X should in theory be a little bit better than the GeForce GT 340 in general. (explain)

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

Texel Rate

The Radeon R7 M260X is a bit (more or less 13%) more effective 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

If using lots of anti-aliasing is important to you, then the Radeon R7 M260X is a better choice, and very much so. (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: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated 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 fill 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.
