GeForce GTX 1050 Ti vs Radeon HD 5850

Intro

Compare all of that to the Radeon HD 5850, which uses a 40 nm design. AMD has set the core speed at 725 MHz. The GDDR5 RAM works at a frequency of 1000 MHz on this particular model. It features 1440(288x5) SPUs along with 72 Texture Address Units and 32 ROPs.

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

Texel Rate

The GeForce GTX 1050 Ti will be a little bit (approximately 19%) faster with regards to anisotropic filtering than the Radeon HD 5850. (explain)

GeForce GTX 1050 Ti		61920 Mtexels/sec
Radeon HD 5850		52200 Mtexels/sec
	Difference: 9720 (19%)

Pixel Rate

The GeForce GTX 1050 Ti is quite a bit (approximately 78%) more effective at anti-aliasing than the Radeon HD 5850, and should be able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 1050 Ti		41280 Mpixels/sec
Radeon HD 5850		23200 Mpixels/sec
	Difference: 18080 (78%)

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 data (counted in MB per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 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 higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
