GeForce GT 340 vs Radeon R7 M260X

Intro

The GeForce GT 340 has a GPU core speed of 550 MHz, and the 512 MB of GDDR5 RAM is set to run at 850 MHz through a 128-bit bus. It also is made up of 96 Stream Processors, 32 TAUs, and 8 ROPs.

Compare all of that to the Radeon R7 M260X, which uses a 28 nm design. AMD has clocked the core frequency at 825 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this particular card. It features 384 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 M260X should be 18% faster than the GeForce GT 340 in general, 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 will be a little bit (more or less 13%) faster with regards to AF 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 will be much (about 50%) faster with regards to FSAA than the GeForce GT 340, and should be able to handle 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.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 number 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 higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
