AMD shows ‘cube’ of four Vega boards for 100 teraflops of processing power

At the AMD Tech Summit, Radeon chief architect Raj Koduri showcased a “cube” that can accommodate up to four Vega GPUs. Together, these would have 100 teraflops of computing power and would be interconnected by means of an as yet unannounced special interface.

According to, Koduri informed the audience that the cube, which has not yet been officially named, can handle 100 teraflops at 16fp half-precision computing. The four boards were prototypes that did not yet contain a GPU. The interface to interconnect the cards would be the unannounced response to NVlink from Nvidia.

A photo has leaked of an apparently private part of the same event. It shows a computer running Doom on what is believed to be an engineering sample of an unannounced AMD video card. It can be seen that it runs in a 4k resolution with a stable frame rate of 68fps. The card has 8GB of HBM2 memory and the hardware ID is 687F:C1, a string of characters that has come across before and presumably belongs to the AMD Radeon RX 490.
