VS

Radeon RX 550 vs Radeon RX Vega 64

Intro

The Radeon RX 550 makes use of a 14 nm design. AMD has set the core frequency at 1100 MHz. The GDDR5 RAM works at a speed of 1750 MHz on this specific card. It features 512 SPUs along with 32 Texture Address Units and 16 ROPs.

Compare those specifications to the Radeon RX Vega 64, which has clock speeds of 1247 MHz on the GPU, and 1890 MHz on the 8192 MB of HBM2 memory. It features 4096 SPUs along with 256 TAUs and 64 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of MB per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 are applied in one second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
