1. ipc impro\u00adve\u00adment is still hig\u00adher than expected
\n2. Focus on impro\u00adving memo\u00adry latency
\n3. avx per\u00adfor\u00admance enhance\u00adments (alt\u00adhough it is esti\u00adma\u00adted that 512 is not supported)
\n4. 7 nm fre\u00adquen\u00adcy pre\u00adview (engi\u00adnee\u00adring sam\u00adple fre\u00adquen\u00adcy has been hig\u00adher than expected)
\n5. More refi\u00adned boost fre\u00adquen\u00adcy step\u00adping (pbo and xfr are more intelligent)
\n6. It is not clear whe\u00adther ryzen will put pcie\u20114.0
\n7. one more thing.\u2026..(ray tracing?!?!)<\/p>\n
