There had been rumours that the next generation of AMD Navi’s core would be “Arcturus”, but AMD officials later confirmed that it was actually a code name for a server-specific speed card product and would not appear in a consumer-grade game card. The BigHorn star, also known as the Makhers, is the brightest star in the Bootes and the brightest star in the northern night sky, ranking fourth in brightness all day, in the same category as AMD’s previously used codename, Vega and Polaris.
Today, hardware exposure experts @KOMACHI_ENSAKA, said that the discovery of a new AMD professional acceleration card “Radeon Instinct MI100”, should be the Arcturus core, the core base frequency 1090MHz, acceleration frequency 1333MHz, equipped with 32GB HBM2 memory, and the entire card power consumption is only 100W.
AMD Radeon Instinct line of products, Vega architecture of the existing two models MI50, MI60, both using 7nm process, respectively, with 4096, 3840 stream processors, with 16/32GB, 32GB HBM2 memory, frequency 1GHz, bit width 4096-bit, bandwidth 1TB/s, the whole card power consumption 300W.
The exact specifications of the Arcturus core are not accurate for the time being, and are said to still be 7nm process and Vega architecture, which does not rule out upgrading to 7nm plus, while the core size will double to 8192 stream processors (128 units), while the memory frequency of 1GHz or 1.2GHz, or 4096-bit width bandwidth is 1.2TB/s.
With the core doubling and power consumption down by a third, the Arcturus core’s efficiency is quite amazing, of course, at a much lower frequency, and the MI50’s acceleration frequency can reach 1725MHz, but even so, the performance of the new core card will certainly be greatly improved, and it is worth looking forward to.
