GeForce GTX 1050 3GB vs Geforce GTX 680

Intro

Compare all of that to the Geforce GTX 680, which comes with a clock speed of 1006 MHz and a GDDR5 memory frequency of 1502 MHz. It also uses 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 Raster Operation Units.

	Difference: 61952 (93%)

Pixel Rate

The GeForce GTX 1050 3GB should be a little bit (more or less 4%) faster with regards to full screen anti-aliasing than the Geforce GTX 680, and also able to handle higher screen resolutions more effectively. (explain)

GeForce GTX 1050 3GB		33408 Mpixels/sec
Geforce GTX 680		32192 Mpixels/sec
	Difference: 1216 (4%)

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 (counted in MB per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better 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 maximum number of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
