GeForce GTX 1050 3GB vs Radeon HD 4790

Intro

The GeForce GTX 1050 3GB features a clock speed of 1392 MHz and a GDDR5 memory frequency of 1750 MHz. It also makes use of a 96-bit memory bus, and makes use of a 14 nm design. It is made up of 768 SPUs, 48 Texture Address Units, and 24 Raster Operation Units.

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

Memory Bandwidth: Bandwidth is the max amount of information (measured in megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 number of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
