GeForce GTX 1050 Ti vs Radeon HD 4790

Intro

Compare all that to the Radeon HD 4790, which comes with GPU clock speed of 600 MHz, and 512 MB of GDDR5 RAM set to run at 800 MHz through a 256-bit bus. It also is made up of 640(128x5) SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 1050 Ti should in theory be a small bit faster than the Radeon HD 4790 in general. (explain)

GeForce GTX 1050 Ti		114688 MB/sec
Radeon HD 4790		102400 MB/sec
	Difference: 12288 (12%)

Texel Rate

The GeForce GTX 1050 Ti will be quite a bit (more or less 223%) more effective at texture filtering than the Radeon HD 4790. (explain)

GeForce GTX 1050 Ti		61920 Mtexels/sec
Radeon HD 4790		19200 Mtexels/sec
	Difference: 42720 (223%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 1050 Ti is superior to the Radeon HD 4790, and very much so. (explain)

GeForce GTX 1050 Ti		41280 Mpixels/sec
Radeon HD 4790		9600 Mpixels/sec
	Difference: 31680 (330%)

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 max amount of information (measured in megabytes per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core 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 output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
