GeForce RTX 3050 vs Radeon HD 7950

Intro

The GeForce RTX 3050 makes use of a 8 nm design. nVidia has set the core speed at 1552 MHz. The GDDR6 memory works at a speed of 1750 MHz on this card. It features 2560 SPUs as well as 80 Texture Address Units and 32 Rasterization Operator Units.

Compare all that to the Radeon HD 7950, which makes use of a 28 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 RAM runs at a frequency of 1250 MHz on this specific card. It features 1792 SPUs along with 112 Texture Address Units and 32 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. 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 rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
