AMD PRO A-Series APU "Desktop Bristol Ridge" vs "Desktop Skylake" Spec
![]()
So, I've been fiddling with BriR/StoR. I have come to some conclusions that need to be tested or verified by others.
1#;
- 28nm Super Low Power, 28nm Advanced, 28nm High Performance Plus are all created with 32nm Geometry.
- 28nm High Performance Advanced however is created with 22nm Geometry. [Which is why we have seen it with 22FDX]
2#;
The architecture used is not "Excavator", but is in fact "Drillcorer" or simply Driller. Other than the inclusion of the Fully Integrated Voltage Regulator.
- I have identified some optimizations to WCC, TLBs, and Vector Processing Unit.
- I have identified some regressions to L1d latency, L2 latency, and an erroneous identification of a 4 MB L3 cache on Bristol Ridge. [44c for L3, 19c for L2, 5c for L1d]
VPU Change;
Pipe 0; FPFMA, FPCVT
Pipe 1; FPFMA, FPXBR
Pipe 2; FPMMA, FPMAL
Pipe 3; FPMAL, FPSTO, FPSHF
WCC only evicts to the L2. Where with Piledriver, it went everywhere. Kaveri retained the same behavior.
Essentially, a fusion of bdver1/2 and bdver3/4. No big boggling changes, everything should performance the same. Except, for workloads that mix Vector FP and Packed Int.

DT Bristol Ridge schedule was for late july, so it shouldnt be long before MBs and APUs are launched, surely next month or early october, i guess that they are waiting for current DT APUs inventories to be low enough, because once BR is launched Kaveri sales will logicaly plummet...
I thought DIY Bristol Ridge on AM4 was due in Octobor, with OEM Bristol Ridge coming before then?

Between Nehalem/SB levels? interesting....FP results in old SUperpi with Carizzo:
