GeForce GTX 1050 3GB vs Radeon HD 4790

Intro

The GeForce GTX 1050 3GB uses a 14 nm design. nVidia has clocked the core frequency at 1392 MHz. The GDDR5 RAM runs at a frequency of 1750 MHz on this specific model. It features 768 SPUs along with 48 Texture Address Units and 24 Rasterization Operator Units.

Compare those specs to the Radeon HD 4790, which features GPU core speed of 600 MHz, and 512 MB of GDDR5 memory running at 800 MHz through a 256-bit bus. It also features 640(128x5) Stream Processors, 32 TAUs, and 16 Raster Operation Units.

GeForce GTX 1050 3GB 86016 MB/sec
Difference: 16384 (19%)

Texel Rate

The GeForce GTX 1050 3GB should be quite a bit (about 248%) faster with regards to anisotropic filtering than the Radeon HD 4790. (explain)

GeForce GTX 1050 3GB 66816 Mtexels/sec
Radeon HD 4790 19200 Mtexels/sec
Difference: 47616 (248%)

Pixel Rate

The GeForce GTX 1050 3GB should be much (more or less 248%) better at full screen anti-aliasing than the Radeon HD 4790, and should be able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX 1050 3GB 33408 Mpixels/sec
Radeon HD 4790 9600 Mpixels/sec
Difference: 23808 (248%)

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.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is worked out by multiplying the total number 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 processed in a 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. The figure is worked out by multiplying the number of Render Output Units by the the core speed of the card. 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 quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
