GeForce GTX 1050 Ti vs Radeon HD 4790

Intro

Compare all of that to the Radeon HD 4790, which uses a 55 nm design. AMD has set the core speed at 600 MHz. The GDDR5 memory runs at a frequency of 800 MHz on this particular model. It features 640(128x5) SPUs as well as 32 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTX 1050 Ti should in theory be a little bit better 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 a lot (approximately 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 superior to the Radeon HD 4790, 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 (measured in MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
