GeForce GTX 260 Core 216 vs GeForce GTX 750

Intro

Compare those specs to the GeForce GTX 750, which uses a 28 nm design. nVidia has set the core frequency at 1020 MHz. The GDDR5 memory works at a speed of 1250 MHz on this card. It features 512 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

Performance-wise, the GeForce GTX 260 Core 216 should in theory be quite a bit superior to the GeForce GTX 750 in general. (explain)

GeForce GTX 260 Core 216		111888 MB/sec
GeForce GTX 750		80000 MB/sec
	Difference: 31888 (40%)

Texel Rate

The GeForce GTX 260 Core 216 will be a lot (more or less 27%) faster with regards to texture filtering than the GeForce GTX 750. (explain)

GeForce GTX 260 Core 216		41472 Mtexels/sec
GeForce GTX 750		32640 Mtexels/sec
	Difference: 8832 (27%)

Pixel Rate

The GeForce GTX 750 is a little bit (more or less 1%) better at anti-aliasing than the GeForce GTX 260 Core 216, and capable of handling higher resolutions while still performing well. (explain)

GeForce GTX 750		16320 Mpixels/sec
GeForce GTX 260 Core 216		16128 Mpixels/sec
	Difference: 192 (1%)

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 transferred across the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the 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 the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
