GeForce GTX 1050 vs Radeon HD 4790

Intro

Compare those specifications to the Radeon HD 4790, which comes with a core clock frequency of 600 MHz and a GDDR5 memory frequency of 800 MHz. It also uses a 256-bit bus, and uses a 55 nm design. It is made up of 640(128x5) SPUs, 32 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce GTX 1050 should theoretically be a 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 (about 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 a lot (more or less 351%) better at full screen anti-aliasing than the Radeon HD 4790, and also will be able to handle higher screen resolutions better. (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 max amount of data (counted in megabytes per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, 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 amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, 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 maximum amount of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
