GeForce GTX 1050 vs GeForce GTX 275

Intro

Compare those specifications to the GeForce GTX 275, which has a core clock frequency of 633 MHz and a GDDR3 memory speed of 1134 MHz. It also makes use of a 448-bit bus, and makes use of a 55 nm design. It is made up of 240 SPUs, 80 TAUs, and 28 Raster Operation Units.

GeForce GTX 1050		75 Watts
GeForce GTX 275		219 Watts
	Difference: 144 Watts (192%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 275 should perform just a bit faster than the GeForce GTX 1050 in general. (explain)

GeForce GTX 275		127008 MB/sec
GeForce GTX 1050		114688 MB/sec
	Difference: 12320 (11%)

Texel Rate

The GeForce GTX 1050 is a small bit (about 7%) more effective at AF than the GeForce GTX 275. (explain)

GeForce GTX 1050		54160 Mtexels/sec
GeForce GTX 275		50640 Mtexels/sec
	Difference: 3520 (7%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 1050 is a better choice, by a large margin. (explain)

GeForce GTX 1050		43328 Mpixels/sec
GeForce GTX 275		17724 Mpixels/sec
	Difference: 25604 (144%)

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 largest amount of data (measured in MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that 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 number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
