If you recall, AMD publicly revealed the first processor to use the AMD Zen microarchitecture on the second day of Computex 2016. Codenamed “Summit Ridge“, the desktop processor will come with eight AMD Zen processor cores that are capable of processing sixteen threads simultaneously.
AMD Zen Sneak Peek
AMD today gave us a sneak peek of the AMD Zen processor architecture. AMD Senior Fellow and Design Engineer, Michael Clark, gave a 26-minute long technical briefing on the AMD Zen architecture at the Hot Chips Symposium in Cupertino, California. Here are the key takeaway points :
- Zen delivers 40% more instructions per clock than the current Excavator core.
- Zen is highly scalable and will be used in every future AMD mobile, desktop or server processor.
- Zen has a better core engine that handles two threads per core, and boasts a large Op Cache, wide micro-op dispatch, as well as larger instruction schedulers, Retire Queue, Load Queue and Store Queue.
- Zen has a better cache system too, with almost double the L1 and L2 bandwidth, and 5X better L3 bandwidth.
- Zen is the first AMD microarchitecture to emphasise low power design, using aggressive clock gating with multi-level regions, as well as other microarchitecture tricks to greatly reduce power consumption.
