GeForce GTX 285 1GB vs GeForce GTX 750 Ti

Intro

Compare all that to the GeForce GTX 750 Ti, which makes use of a 28 nm design. nVidia has clocked the core frequency at 1020 MHz. The GDDR5 RAM works at a frequency of 1350 MHz on this model. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

GeForce GTX 750 Ti		40800 Mtexels/sec
	Difference: 11040 (27%)

Pixel Rate

The GeForce GTX 285 1GB should be quite a bit (approximately 27%) faster with regards to FSAA than the GeForce GTX 750 Ti, and also will be able to handle higher resolutions better. (explain)

GeForce GTX 285 1GB		20736 Mpixels/sec
GeForce GTX 750 Ti		16320 Mpixels/sec
	Difference: 4416 (27%)

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 max amount of data (counted in MB per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 are applied in one second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
