GeForce GT 340 1GB vs Radeon R7 M260X

Intro

Compare all of that to the Radeon R7 M260X, which uses a 28 nm design. AMD has set the core speed at 825 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this particular card. It features 384 SPUs along with 24 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R7 M260X should in theory be just a bit better than the GeForce GT 340 1GB in general. (explain)

Radeon R7 M260X		64000 MB/sec
GeForce GT 340 1GB		54400 MB/sec
	Difference: 9600 (18%)

Texel Rate

The Radeon R7 M260X will be a bit (more or less 13%) more effective at AF than the GeForce GT 340 1GB. (explain)

Radeon R7 M260X		19800 Mtexels/sec
GeForce GT 340 1GB		17600 Mtexels/sec
	Difference: 2200 (13%)

Pixel Rate

The Radeon R7 M260X will be much (approximately 50%) more effective at anti-aliasing than the GeForce GT 340 1GB, and should be capable of handling higher screen resolutions more effectively. (explain)

Radeon R7 M260X		6600 Mpixels/sec
GeForce GT 340 1GB		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 maximum amount of information (in units of MB per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
