GeForce GTX 550 Ti vs GeForce GTX 960

Intro

Compare all of that to the GeForce GTX 960, which features a GPU core clock speed of 1127 MHz, and 2048 MB of GDDR5 RAM set to run at 1750 MHz through a 128-bit bus. It also is comprised of 1024 SPUs, 64 TAUs, and 32 ROPs.

GeForce GTX 550 Ti		28800 Mtexels/sec
	Difference: 43328 (150%)

Pixel Rate

The GeForce GTX 960 should be much (more or less 67%) better at FSAA than the GeForce GTX 550 Ti, and able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 960		36064 Mpixels/sec
GeForce GTX 550 Ti		21600 Mpixels/sec
	Difference: 14464 (67%)

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 data (counted in MB per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 can be processed per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
