GeForce GTX 285 1GB vs GeForce GTX 750

Intro

Compare those specs to the GeForce GTX 750, which features a core clock frequency of 1020 MHz and a GDDR5 memory frequency of 1250 MHz. It also uses a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 512 SPUs, 32 TAUs, and 16 ROPs.

GeForce GTX 750		32640 Mtexels/sec
	Difference: 19200 (59%)

Pixel Rate

The GeForce GTX 285 1GB is quite a bit (about 27%) more effective at anti-aliasing than the GeForce GTX 750, and also capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 285 1GB		20736 Mpixels/sec
GeForce GTX 750		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: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, 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 the video card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units 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 fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
