Nvidia Titan X vs Radeon RX 550

Intro

The Nvidia Titan X uses a 16 nm design. nVidia has clocked the core frequency at 1417 MHz. The GDDR5X RAM is set to run at a frequency of 1251 MHz on this particular model. It features 3584 SPUs along with 224 Texture Address Units and 96 Rasterization Operator Units.

Compare those specifications to the Radeon RX 550, which comes with a clock speed of 1100 MHz and a GDDR5 memory speed of 1750 MHz. It also makes use of a 128-bit bus, and makes use of a 14 nm design. It is made up of 512 SPUs, 32 TAUs, and 16 ROPs.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
