Sunny Cove


We covered Sunny Cove microarchitecture a while ago, but here is a refresher on what has changed. Internally the CPU is larger, and the cache has been increased, the CPU internally can handle a lot more as Intel has widened the microarchitecture, and technologies such as branch prediction have been optimized to improve accuracy and reduce latency.


Compared to Skylake, Sunny Cove will have 50% more L1 cache, 100% more L2 cache, a larger out of order window, and will be capable of many more loads and stores. It is a serious improvement over Skylake.


Intel is also integrating its deep learning boost instruction set, which is much like an improved AVX and is already available with Cascade Lake.


With an impressive 18% IPC increase, Intel is poised to impress many with their new microarchitecture.


Performance is also on track to keep up with the generational performance improvement, even with the decrease in frequency which was hinted in Intel's first 10nm process briefing.
