GeForce GT 340 vs Radeon R7 260X

Intro

Compare all that to the Radeon R7 260X, which has a core clock frequency of 1100 MHz and a GDDR5 memory speed of 1625 MHz. It also makes use of a 128-bit memory bus, and makes use of a 28 nm design. It is comprised of 896 SPUs, 56 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 340		69 Watts
Radeon R7 260X		115 Watts
	Difference: 46 Watts (67%)

Memory Bandwidth

Theoretically, the Radeon R7 260X should perform a lot faster than the GeForce GT 340 in general. (explain)

Radeon R7 260X		104000 MB/sec
GeForce GT 340		54400 MB/sec
	Difference: 49600 (91%)

Texel Rate

The Radeon R7 260X will be quite a bit (approximately 250%) more effective at AF than the GeForce GT 340. (explain)

Radeon R7 260X		61600 Mtexels/sec
GeForce GT 340		17600 Mtexels/sec
	Difference: 44000 (250%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R7 260X is the winner, and very much so. (explain)

Radeon R7 260X		17600 Mpixels/sec
GeForce GT 340		4400 Mpixels/sec
	Difference: 13200 (300%)

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 maximum amount of information (counted in MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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 ability to get to the max fill rate.
