Wow a fanless Radeon RX 5700 XT Graphics Card from Sapphire … but this is one is designed for rack mount servers and devices.
Taken from VideoCardz … Sapphire announced a new GPRO model called X070 Compute Card. This SKU was designed for professional use, such as computations on a bigger scale. Sapphire is showcasing the card in a server environment, where the airflow is already provided by the enclosure.
The card is based on Radeon RX 5700 XT SKU featuring Navi 10 GPU. This model features 40 Compute Units with 2560 Stream Processors. Sapphire’s GPRO model is equipped with 8GB of GDDR6 memory clocked at 14 Gbps. In terms of GPU frequency, the GPRO X070 features AMD reference specs of 1607 / 1755 / 1905 MHz (base, game, and boost clock respectively). The fact that this card has a game clock listed in official specifications may sound strange considering that the card is designed for a professional workload, but technically, this is just a custom Radeon RX 5700 XT.
Interestingly GPRO X070 has a secondary BIOS with ‘Efficiency Mode’. In this mode, the clock speed is reduced to 1500 / 1700 / 1750 MHz with the memory clock kept at 14 Gbps. It is unclear what exactly is the purpose of this mode, but reduced clock speeds are often seen in graphics cards in mining environments.
