A ghost from the previous emerged on a Reddit thread (opens in new tab) the opposite day. A consumer has managed to get his arms on a Radeon Professional prototype that leverages your entire Vega 20 die.
AMD has produced many graphics playing cards and accelerators based mostly on the Vega 20 silicon. However solely the extra unique and area of interest fashions got here with the fully-enabled Vega 20 die, which homes 64 CUs, equal to 4,096 shading models. The small checklist contains the 2018-era Radeon Intuition MI60, which targets the AI and deep studying market, plus the Radeon Professional Vega II and Radeon Professional Vega II Duo, which wound up in choose Mac Professional machines. Sadly, the retail market obtained to reap the total advantages of what Vega 20 needed to provide.
The mysterious Radeon Professional from the Reddit thread sports activities the identical aesthetics because the Radeon Professional V420, a professional-grade graphics card that additionally by no means made it to the market. Images of the PCB reveal the large Vega 20 silicon, which measures 331 mm², with 4 stacks of high-speed HBM2 reminiscence. As well as, the prototype options one 8-pin PCIe energy connector and a 6-pin PCIe energy connector, an appropriate configuration for as much as 300W.
Because it’s unreleased {hardware}, GPU-Z had issue determining the Radeon Professional graphics card. Nevertheless, in keeping with the software program, it has the identical system ID because the Radeon Intuition MI60. As well as, the utility experiences SK hynix because the producer of the HBM2 reminiscence, however in actuality it is Samsung.

In keeping with the proprietor, the Radeon Professional graphics card comes with two completely different units of firmware. The first firmware has the next energy restrict with 32GB of 1,600 Mbps reminiscence, whereas the second firmware includes a extra modest energy restrict with a reminiscence quota of 31.984GB. As well as, the graphics card sports activities the standard blower-style cooler, which seems to be fairly good and even has a little bit of RGB lighting to it. The Redditor reported temperatures lower than 80 levels Celsius
beneath load, with the cooling fan hitting speeds of three,800 RPM. For reference, the cooling fan has a most rotational pace of 5,000 RPM.
The Radeon Professional prototype hits 1,700 MHz, so it is nicely throughout the vary of the opposite Vega 20-powered SKUs. The Radeon Professional Vega II tops out at 1,720 MHz, and solely the Radeon Intuition MI60 flaunts a 1,800 MHz enhance clock pace.
Efficiency could possibly be higher, partly as a result of it is a prototype and wishes correct software-level assist. Because of this, the Radeon Professional graphics card would not carry out 100% throughout real-world checks. Nonetheless, it delivered a double-precision efficiency of as much as 6.4 TFLOPs, round 14% slower than the Radeon Intuition MI60.
It stays a thriller why AMD backpedaled and did not launch the Radeon Professional V420. It could have been a really aggressive skilled graphics card on the time.
