Intel Unveils a Clean-slate CPU Core Architecture Codenamed "Sunny Cove"
Intel today unveiled its first clean-slate CPU core micro-architecture since "Nehalem," codenamed "Sunny Cove." Over the past decade, the 9-odd generations of Core processors were based on incrementally refined descendants of "Nehalem," running all the way down to "Coffee Lake." Intel now wants a clean-slate core design, much like AMD "Zen" is a clean-slate compared to "Stars" or to a large extent even "Bulldozer." This allows Intel to introduce significant gains in IPC (single-thread performance) over the current generation. Intel's IPC growth curve over the past three micro-architectures has remained flat, and only grew single-digit percentages over the generations prior.
It's important to note here, that "Sunny Cove" is the codename for the core design. Intel's earlier codenaming was all-encompassing, covering not just cores, but also uncore, and entire dies. It's up to Intel's future chip-designers to design dies with many of these cores, a future-generation iGPU such as Gen11, and a next-generation uncore that probably integrates PCIe gen 4.0 and DDR5 memory. Intel details "Sunny Cove" as far as mentioning IPC gains, a new ISA (new instruction sets and hardware capabilities, including AVX-512), and improved scalability (ability to increase core-counts without running into latency problems).
