GeForce GT 340 vs Radeon R7 M260X

Intro

Compare that to the Radeon R7 M260X, which features a clock frequency of 825 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 128-bit 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 perform just a 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 a small bit (more or less 13%) faster with regards to 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 much (about 50%) better at AA than the GeForce GT 340, and should be able to handle higher screen resolutions while still performing well. (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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
