Powerful Polaris "C99" Flagship GPU, Based On AMD's GCN 4.0 Architecture, Passes RRA Certification

A calendar month ago I reported on an unusually powerful AMD GPU that I spotted in Zauba shipping manifests.The nomenclature analysis on the particular GPU revealed that this is quite clearly, the flagship part of AMD'southward "C9X" generation of GPUs. Almost a calendar month subsequently the Polaris production was spotted, information technology has received RRA Certification – marking another milestone in its path to consumer shelves. The particular RRA certificate tin exist plant here.

Powerful AMD GCN four.0 flagship 'C99' passes RRA certification

AMD uses a predictable nomenclature while naming its test boards. All of these boards start with the letter C (which probably stands for consumer) followed by five numbers. The first digit after C almost certainly denotes the generation of the graphic card. The 2nd digit manifestly represents the relative rank of the bit in the same lineup. The numbers that follow are much harder to guess at externally and can draw whatsoever specification whatsoever. Since the numbering follows a very obvious trend however, its not that hard to figure out how AMD builds the lineup. Before nosotros become whatsoever farther, take a expect below.

Hawaii boards for were named C6XXXX, Tonga boards C7XXXX and Fiji boards C8XXXX. In fact, if we are being specific nigh information technology than the verbal code names were:

Hawaii XT had the C 6 7101 code name.

Tonga had the C76501 code name.

Republic of the fiji islands XT had the C88001 code proper name.

By the same logic, Polaris (and other GCN four.0) boards should take the C9XXXX nomenclature, and this is something we have already seen before. The Baffin XT GPU listed on Zauba had the Cix8101 code name, which is clearly a Polaris die. Apart from that nosotros spotted a total of two more than variants on Zauba which are probably besides Polaris GPUs. Go on in heed that the INR value given to these dies is just the insurance value (and does non depict the expected MSRP of the aforementioned).

RRA is S Korea'southward National Radio Research Agency and any silicon based electronic must receive their postage stamp of approval before it'southward immune to exist a consumer production. The certification also marks the final stages of the design of a particular GPU (no changes tin be fabricated afterward this certification is received) and means that all the concluding touches on the flagship Polaris GPU have been fabricated. The certification number is "MSIP-REM-ATI-102-C99301" and it'due south the last six numbers that are of particular interest to the states. The document covers iv sub-variants of the production as well (C99302, C99303, C99304, C99305) but we can tell from the nomenclature that the changes are not significant enough to constitute cloth information.

AMD Vega 10, Polaris 10, Polaris 11 Feature *Not to scale.

The certificate date is of earlier this month (viii^th April 2022) and shows that AMD is well on track in the production of its next generation graphics cards. We take previously seen other Polaris boards such as the Polaris xi "C91" variant get RRA's stamp of approval; which constitutes the modest Polaris board equally clear from the nomenclature. Hither is the matter nonetheless, up till now we accept spotted effectually 4 distinct variations of AMD's 4th generation GCN products:

C9i103 Lath (Polaris xi)
C94402 Board (Polaris eleven)
C98101 Board (Polaris 10)
C99398 Board (Unknown Flagship, Full Powered Polaris 10 or Vega 10?)

To beginning of with, nosotros have the C91XXX boards which clearly form the lowest tier of Polaris GPUs out there. This is probably the Nano sized Polaris 11 board we have seen before. Then come boards function of the C94XXX lineup which are probably the full-fledged version of Polaris eleven. It could also be a cutting down version of Polaris ten also; in either example, this is the mid-end variant of the Polaris lineup that we will be seeing soon. This constitutes the "real" entry level GPU from AMD's 14nm FinFET lineup.

Farther up ahead, we have the C98XXX board, which is without a incertitude, the Polaris x GPU. Shipping data from Zauba has actually identified this detail GPU as Baffin XT. Which means nosotros are looking at the cutting down variant of Polaris 10. The full-fledged variant (previously known as Ellesmere) is what forms the terminal flagship of AMD's 14nm FinFET GPUs. This is the very same board listed as C99XXX in RRA's certificate. We have already heard rumblings about the specifications and arrival dates of the Polaris lineup but if in that location is 1 thing we can say for certain, information technology is this: the flagship GCN 4.0 GPU is going to be a beast of a graphics card.
