Radeon RX 5700 XT vs Radeon RX Vega 64

Intro

The Radeon RX 5700 XT makes use of a 7 nm design. AMD has set the core speed at 1605 MHz. The GDDR6 RAM is set to run at a speed of 14000 MHz on this specific model. It features 2560 SPUs along with 160 Texture Address Units and 64 ROPs.

Compare those specifications to the Radeon RX Vega 64, which comes with GPU core speed of 1247 MHz, and 8192 MB of HBM2 RAM running at 1890 MHz through a 2048-bit bus. It also is comprised of 4096 Stream Processors, 256 TAUs, and 64 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
