GeForce GTX 1050 Ti vs Radeon HD 4790

Intro

The GeForce GTX 1050 Ti uses a 14 nm design. nVidia has set the core speed at 1290 MHz. The GDDR5 RAM works at a speed of 1750 MHz on this model. It features 768 SPUs as well as 48 TAUs and 32 ROPs.

Compare those specs to the Radeon HD 4790, which features a core clock speed of 600 MHz and a GDDR5 memory frequency of 800 MHz. It also features a 256-bit memory bus, and makes use of a 55 nm design. It is made up of 640(128x5) SPUs, 32 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1050 Ti should be a little bit faster than the Radeon HD 4790 overall. (explain)

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

Texel Rate

The GeForce GTX 1050 Ti should be much (about 223%) faster with regards to anisotropic 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 high levels of AA is important to you, then the GeForce GTX 1050 Ti is superior to the Radeon HD 4790, by a large margin. (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.

Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total amount of texture units 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 maximum number of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
