The PCI ID Repository

Name: Radeon HD 6310

Found on AMD Fusion DB-FT1 Development Board.

How is this related to ID 9802?
???Maybe ID 9802 was used early for Radeon HD 6250/6310 and later split up into 9804->HD 6250, 9806->HD 6310??? (Just guessing!)

http://www.amd.com/uk/Documents/49286A_Embedded_Solutions_Brief_FT1.pdf
says "AMD Embedded G-T56N processor with AMD Radeon HD 6310 graphics" twice(!), and
http://www.ibase-i.com.tw/2009/dbft1.html
says the same (although they may have copied it from the AMD's pdf).

So, now what? A typo? But which of the two is correct? Or two minor GPU variants sharing one ID?

If you're really sure about that, you could name it Wrestler [Radeon HD 6300 Series]

I think I got it figured out now! http://www.notebookcheck.net/AMD-Radeon-HD-6320.54746.0.html states the difference between 6310 and 6320 is a "Turbo Core" feature. And some AMD document mentiones "GPU Sclk Boost" (I think that's the same thing!) was enabled for the G-T56N when upgrading the silicon from the B0 to the C0 stepping. They must've changed the PCI ID accordingly: G-T56N stepping B0 reports a Radeon 6310 (9802) and stepping C0 identifies itself as Radeon 6320 (9806). (AFAICT the same happened to the G-T40N: Radeon 6250 -> 6290, but I don't have hardware to check.)

So "Wrestler [Radeon HD 6320]" for device 9806 is correct. The documentation for my DB-FT1 Development Board is wrong, AMD forgot to update it when moving from B0 to C0 silicon!
