GeForce GTS 250 512MB vs GeForce GTX 1050

Intro

Compare all of that to the GeForce GTX 1050, which comes with a clock speed of 1354 MHz and a GDDR5 memory speed of 1750 MHz. It also uses a 128-bit memory bus, and uses a 14 nm design. It is made up of 640 SPUs, 40 TAUs, and 32 Raster Operation Units.

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 1050 is a better choice, by far. (explain)

GeForce GTX 1050		43328 Mpixels/sec
GeForce GTS 250 512MB		11808 Mpixels/sec
	Difference: 31520 (267%)

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 past the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR type 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 anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
