GeForce GTX 1050 3GB vs Geforce GTX 690

Intro

Compare those specifications to the Geforce GTX 690, which comes with a core clock speed of 915 MHz and a GDDR5 memory frequency of 1502 MHz. It also features a 256-bit memory bus, and makes use of a 28 nm design. It is made up of 1536 SPUs, 128 Texture Address Units, and 32 ROPs.

GeForce GTX 1050 3GB		86016 MB/sec
	Difference: 298496 (347%)

Texel Rate

The Geforce GTX 690 will be a lot (more or less 251%) more effective at AF than the GeForce GTX 1050 3GB. (explain)

Geforce GTX 690		234240 Mtexels/sec
GeForce GTX 1050 3GB		66816 Mtexels/sec
	Difference: 167424 (251%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Geforce GTX 690 is the winner, by far. (explain)

Geforce GTX 690		58560 Mpixels/sec
GeForce GTX 1050 3GB		33408 Mpixels/sec
	Difference: 25152 (75%)

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: Memory bandwidth is the max amount of information (measured in MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
