GeForce GTX 1050 Ti vs Radeon HD 4790

Intro

Compare all of that to the Radeon HD 4790, which has core speeds of 600 MHz on the GPU, and 800 MHz on the 512 MB of GDDR5 RAM. It features 640(128x5) SPUs along with 32 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce GTX 1050 Ti should theoretically be a small bit superior to 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 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 resolution is important to you, then the GeForce GTX 1050 Ti is a better choice, by far. (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: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once 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, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock 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 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 reach the max fill rate.
