GeForce GTX 1050 vs Radeon HD 4790

Intro

Compare all of that to the Radeon HD 4790, which uses a 55 nm design. AMD has clocked the core speed at 600 MHz. The GDDR5 memory works at a frequency of 800 MHz on this card. It features 640(128x5) SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 1050 will be 12% faster than the Radeon HD 4790 overall, because of its higher data rate. (explain)

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

Texel Rate

The GeForce GTX 1050 is much (more or less 182%) faster with regards to AF than the Radeon HD 4790. (explain)

GeForce GTX 1050		54160 Mtexels/sec
Radeon HD 4790		19200 Mtexels/sec
	Difference: 34960 (182%)

Pixel Rate

The GeForce GTX 1050 will be a lot (more or less 351%) more effective at full screen anti-aliasing than the Radeon HD 4790, and should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 1050		43328 Mpixels/sec
Radeon HD 4790		9600 Mpixels/sec
	Difference: 33728 (351%)

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 largest amount of information (in units of MB per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of 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.
