GeForce GTX 960 vs Radeon RX 550

Intro

The GeForce GTX 960 uses a 28 nm design. nVidia has set the core frequency at 1127 MHz. The GDDR5 memory works at a speed of 1750 MHz on this model. It features 1024 SPUs along with 64 TAUs and 32 Rasterization Operator Units.

Compare those specs to the Radeon RX 550, which features a core clock speed of 1100 MHz and a GDDR5 memory speed of 1750 MHz. It also uses a 128-bit bus, and uses a 14 nm design. It features 512 SPUs, 32 TAUs, and 16 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, 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 maximum number of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
