GeForce GTX 750 vs Radeon Pro Duo

Intro

Compare those specifications to the Radeon Pro Duo, which has a core clock speed of 1000 MHz and a HBM memory frequency of 500 MHz. It also uses a 4096-bit memory bus, and makes use of a 28 nm design. It is comprised of 4096 SPUs, 256 TAUs, and 64 Raster Operation Units.

Pixel Rate

The Radeon Pro Duo is quite a bit (more or less 684%) faster with regards to AA than the GeForce GTX 750, and should be able to handle higher resolutions while still performing well. (explain)

Radeon Pro Duo		128000 Mpixels/sec
GeForce GTX 750		16320 Mpixels/sec
	Difference: 111680 (684%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The number 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 fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
