GeForce GTX 1050 vs GeForce GTX 275

Intro

Compare that to the GeForce GTX 275, which makes use of a 55 nm design. nVidia has set the core frequency at 633 MHz. The GDDR3 memory is set to run at a frequency of 1134 MHz on this model. It features 240 SPUs as well as 80 Texture Address Units and 28 Rasterization Operator Units.

Texel Rate

The GeForce GTX 1050 will be a bit (about 7%) faster with regards to anisotropic filtering than the GeForce GTX 275. (explain)

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

Pixel Rate

The GeForce GTX 1050 is quite a bit (about 144%) faster with regards to full screen anti-aliasing than the GeForce GTX 275, and will be able to handle higher screen resolutions without losing too much performance. (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: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 number of texture map elements (texels) that are 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 the texel rate, the better the card will be at 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 that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
