GeForce GTX 1050 vs Radeon HD 5850

Intro

Compare all of that to the Radeon HD 5850, which has core speeds of 725 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 1440(288x5) SPUs as well as 72 TAUs and 32 ROPs.

GeForce GTX 1050		114688 MB/sec
	Difference: 13312 (12%)

Texel Rate

The GeForce GTX 1050 will be a bit (about 4%) better at texture filtering than the Radeon HD 5850. (explain)

GeForce GTX 1050		54160 Mtexels/sec
Radeon HD 5850		52200 Mtexels/sec
	Difference: 1960 (4%)

Pixel Rate

The GeForce GTX 1050 should be quite a bit (more or less 87%) better at anti-aliasing than the Radeon HD 5850, and should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 1050		43328 Mpixels/sec
Radeon HD 5850		23200 Mpixels/sec
	Difference: 20128 (87%)

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 maximum amount of information (counted in MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it 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 AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
