They aren't replacing each other at this point.Beside no mention is made, even it was posted in this forum, that there s a native 2C/4T Raven Ridge, one has to wonder why they released this SKU if it were to be replaced by a chimeric FDSOI based Stoney Ridge.
Stoney Ridge successors are ~$300 and lower targeted in laptops. ~25% of AMD's market
Raven2 successors are ~$300 and up targeted in laptops. ~40% of AMD's market.
Raven/Renoir successors are $700 and up targeted in laptops. ~35% of AMD's market.
There is subtle differences with 65h and 70h models versions of Excavator. Why would they need to improve on a product that is uncontested within its field.15h has not had a new CPU design since Carrizo, which launched in 2015!
AMD has only shown their compute(HP) x86 core roadmap. AMD had subtlely changed the naming of Excavator with Stoney. To their mobile(LP) core architecture.
Excavator = the core for Entry, Essential, Budget SoCs.
Zen = the core for Mainstream, Premium, Enthusiast SoCs.
It might not be on a roadmap, but there is an architecture after Excavator. That happens to not be Zen. Why else stop-gap and release A9-9420, A9-9425, A9-9435.. we have seen this behavior before a decade ago.
"Up to 52% Higher CPU Performance over previous generation with 'Excavator' cores in Entry-level."
"Incredible 52% CPU improvement over A8-7410"
However, when Ryzen 3 3200u/Athlon 300u comes around, they do not compare them to the A9-9425(2018 model)/A6-9225(2018 model). Instead, they compare only towards Intel, implying this is a new market section between big Raven and small Stoney. While, also registering A9-9435/A6-9235 for USB support. We know those are coming out because of A4-9120e.
We do not know exactly the new core will be but we do know the strong points of cluster-based multithreading.
- Better area, power, performance scaling than SMT and CMP.
- Reduces complexity to the PMU and interconnect. A single module is virtually a single core to the power distribution/data transport architecture.
- Dual-core CMP same clock = dual-core CMT same clock, quad-core or dual-core w/ SMT same clock = quad-core CMT same clock.
However, they use the same numbers as Zen. Meaning if you are paying attention, XV2 is to Zen2 from Zen1 levels of improvement at minimum.
