GeForce GTS 150 vs GeForce GTX 560

Intro

The GeForce GTS 150 features a core clock frequency of 740 MHz and a GDDR3 memory speed of 500 MHz. It also makes use of a 256-bit bus, and makes use of a 55 nm design. It is comprised of 128 SPUs, 64 TAUs, and 16 Raster Operation Units.

Compare all that to the GeForce GTX 560, which comes with a core clock frequency of 810 MHz and a GDDR5 memory speed of 1001 MHz. It also makes use of a 256-bit bus, and uses a 40 nm design. It is comprised of 336 SPUs, 56 TAUs, and 32 Raster Operation Units.

The GeForce GTX 560 should theoretically perform a lot faster than the GeForce GTS 150 in general. (explain)

GeForce GTX 560 128128 MB/sec
GeForce GTS 150 32000 MB/sec
Difference: 96128 (300%)

Texel Rate

The GeForce GTS 150 should be a bit (about 4%) more effective at texture filtering than the GeForce GTX 560. (explain)

GeForce GTS 150 47360 Mtexels/sec
GeForce GTX 560 45360 Mtexels/sec
Difference: 2000 (4%)

Pixel Rate

The GeForce GTX 560 should be much (approximately 119%) more effective at AA than the GeForce GTS 150, and should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 560 25920 Mpixels/sec
GeForce GTS 150 11840 Mpixels/sec
Difference: 14080 (119%)

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 max amount of information (measured in megabytes per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units of the card 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
