This seriously needs to not be circulated anymore.
1) This is not a GPU design, it is an APU design.
The SPU's or Serial Processing Units are simply Bulldozer-esque "Modules".
It also has a northbridge and southbridge.
The memory units are for DDR3, not GDDR5 (which is what you would normally use for a high power GPU).
It has a HyperTransport bus. There is no useful purpose to have this on a GPU.
2) This is an Opteron APU.
The RAM is ECC which is not yet a mainstream consumer part.
It includes an ARM security module, which has been a part of Opteron CPUs for a little while.
It has platform management capabilities, only found in servers.
It has Advanced Server RAS (see http://www.intel.com/content/www/us/en/servers/reliability-availability-and-serviceability-for-the-always-on-enterprise-paper.html)
