GeForce GTX 275 vs GeForce GTX 960

Intro

Compare those specs to the GeForce GTX 960, which uses a 28 nm design. nVidia has clocked the core frequency at 1127 MHz. The GDDR5 memory is set to run at a speed of 1750 MHz on this particular card. It features 1024 SPUs along with 64 Texture Address Units and 32 ROPs.

GeForce GTX 275		50640 Mtexels/sec
	Difference: 21488 (42%)

Pixel Rate

The GeForce GTX 960 will be much (approximately 103%) faster with regards to anti-aliasing than the GeForce GTX 275, and also will be able to handle higher resolutions better. (explain)

GeForce GTX 960		36064 Mpixels/sec
GeForce GTX 275		17724 Mpixels/sec
	Difference: 18340 (103%)

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: Memory bandwidth is the largest amount of data (counted in MB per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher 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 applied in one second. This number is worked out by multiplying the total amount of texture units of the card 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 processed per second.

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