GeForce GT 340 vs Radeon R7 M260X

Intro

Compare those specs to the Radeon R7 M260X, which makes use of a 28 nm design. AMD has clocked the core frequency at 825 MHz. The GDDR5 memory works at a speed of 1000 MHz on this card. It features 384 SPUs along with 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 M260X should be 18% faster than the GeForce GT 340 overall, because of its greater data rate. (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%) 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 should be much (approximately 50%) faster with regards to FSAA than the GeForce GT 340, and also should be capable of handling higher 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: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be transported over the external memory interface within a second. It is calculated 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 it uses DDR5, multiply by 4 instead. 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 are applied in one second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
