Each generation, the manufacturers create a series of cards, with set vRAM and SIMD Cores. The market is split into three categories: server, professional, and consumer. Consumer cards are cheapest and are primarily targeted for the video game market. Professional cards have better driver support for 3d programs like Autocad. Finally, server cards provide virtualization services, allowing cloud companies to virtually split their cards between customers.

While Consumer class GPUs cost anywhere from $100 to $1000. Professional cards can run to $2000, while server and professional class cards have more vRAMcan cost as much as $10, consumer cards are more than adequate starting points for GPU Programmers000.

GPUs use high-bandwidth RAM, such as GDDR6 or HBM2. These specialized RAM GDDR6 and HBM2 are designed for the extremely parallel nature of GPUs, and can provide 200GBps to 1000GBps throughput. In comparison: a typical DDR4 channel can provide 20GBps. A dual channel desktop will typically have under 50GBps bandwidth to DDR4 main memory.

NVidia's consumer line of cards is Geforce, branded with RTX or GTX labels. Nvidia's professional line of cards is "Quadro". Finally, Tesla cards constitute NVidiaNvidia's server lineof cards is "Tesla".
