At the Taipei Computer Show, AMD presented the 7nm CPU processor and 7nm GPU graphics card for the first time. The former is EPYC in the server field, and the latter is an upgraded version of the existing 14nm Vega.
AMD said 7nm Vega is currently in trial production and will be released in the second half of this year. The first products are Radeon Instinct calculation cards, followed by Radeon game cards.
AMD did not disclose the specific details of the 7nm Vega core, but at least the core area can be roughly estimated to see how much the upgrade 7nm process can bring.
We found an AMD CEO, Dr. Su Zifeng, holding a 7nm EPYC CPU and two core photos of 7nm Vega at the same time.
7nm EPYC is still SP3 package style, size does not change, is still 58.5 × 75.4 mm, can be calculated that each side of the 7nm Vega package core is about 47.8 mm.
The side length of the current 14nm Vega package core is 47.5mm, which is abnormally close, which means it will not change at 7nm. It is simple.
The 14nm Vega core has an area of 486 square millimeters, but its estimated area before publication was 510 square millimeters. Taking this error into account, it can be concluded that The 7nm Vega has a core area of 285-298mm2, which is no more than 300mm2.
In other words, After upgrading the 7nm process, Vega core will shrink by almost 40%!
It is conceivable that the frequency of 7nm Vega will have higher performance, and power consumption and heating will be better controlled. It is worth looking forward to!
