Earlier today, we heard about AMD’s new server acceleration card, the Radeon Instinct MI100, which is larger in the core but less power, which is incredible. Now, TechPowerUp has discovered that someone has uploaded the card’s BIOS, and has further confirmed its specifications.
BIOS file information shows that the MI100 device ID string is “0x1002 0x738C”, confirmed from AMD, code-named Arcturus (Bighorn), BIOS file version is “000.000.000.000.013547”, fresh out on January 23 this year.
Combined with the string “MI100 D34303 A1 XL 200W 32GB 1000M” and related information, mi100 has a memory capacity of 32GB HBM2, optional Samsung (KHA8849) 01X,SK Hynix (H5VR64ESA8H) particles, frequency 1GHz, in line with Samsung,SK Hynix official specifications, if continue to match 4096-bit bit width, the bandwidth is 1TB/s.
200W is power consumption, is undoubtedly quite low, to know 64 computing units, 4096 stream processors of the existing computing card Radeon Instinct MI60 power consumption is 300W, the same size of the game card RX Vega 64 is also about 300W (water-cooled version is 345W), The MI100 can basically double the core size to 128 cell computing units and 8,196 stream processors.
Browse the BIOS file can also find a number of frequency values, such as 1334MHz, 1091MHz, 1000MHz, 1200MHz, 1403MHz, according to the AMD graphics sample law, 1334MHz is the core of the highest frequency, 1091MHz is the base frequency, 1000MHz corresponds to the memory frequency.
Such a core frequency is undoubtedly quite low, to know that the MI50 can accelerate to 1725MHz (MI60 not announced), but even so, in the core size increased by 1 x, the core frequency reduced by about 1/4, can reduce power consumption by 1/3, no doubt indicates that Arcturus core energy efficiency is very high, in the architectural redesign at the same time, may also be upgraded to 7nm plus process.
The exact architecture of the Arcturus core is not certain, but the odds are based on an upgrade to Vega rather than a Navi- like, which locates the game card, and from the code name, Arcturus Vega, And Navi are constellations.
