GeForce GTX 1050 Ti vs Radeon HD 4790

Intro

Compare that to the Radeon HD 4790, which comes with a clock frequency of 600 MHz and a GDDR5 memory frequency of 800 MHz. It also makes use of a 256-bit bus, and makes use of a 55 nm design. It features 640(128x5) SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 1050 Ti, in theory, should be just a 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 a lot (more or less 223%) better at 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 lots of anti-aliasing is important to you, then the GeForce GTX 1050 Ti is a better choice, 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.

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (counted in megabytes per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units 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 processed in a second.

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