GeForce GTX 1050 vs Radeon HD 4790

Intro

Compare all that to the Radeon HD 4790, which comes with core clock speeds of 600 MHz on the GPU, and 800 MHz on the 512 MB of GDDR5 memory. It features 640(128x5) SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTX 1050 should in theory be a little bit superior to the Radeon HD 4790 overall. (explain)

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

Texel Rate

The GeForce GTX 1050 should be quite a bit (approximately 182%) more effective at 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 is quite a bit (about 351%) faster with regards to FSAA than the Radeon HD 4790, and also able to handle higher resolutions while still performing well. (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: Bandwidth is the largest amount of information (counted in MB per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it 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 AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
