Right at the very end, we see Whiskey Lake performing +42% above Broadwell, and Ice Lake performing +47% above Broadwell. A quick calculation of 1.47/1.42 means that even Intel is only predicting an absolute gain of ~3.5% for Ice Lake over current generation systems.
The reason why the difference is so small is because of IPC and frequency. Intel is touting a median IPC advantage on the new Sunny Cove cores of +18% against Skylake. That isn’t something we were able to test in the short time we had with the system, but +18% should provide a healthy bump – we actually see a number of key microarchitectural improvements bubble up through in our SPEC testing.
But at the same time, the frequency has decreased – our Whiskey Lake Huawei Matebook system was +500 MHz on the base frequency (+38%), and +700 MHz on the turbo frequency (+18%). If it were not for the vast increase in memory speed, moving from LPDDR3-2133 to LPDDR4X-3733, one might have predicted that the Core i7-1065G7 Ice Lake processor and the Core i7-8565U Whisky Lake processor would have performed equally.
IIRC malo by tam byť 50% viac cache, a ak robili väčšie zmeny v organizácii tak by to ešte mohlo byť neoptimalizované.Key changes from Sunny Cove

Dokonce prý se šušká z interních zdrojů, že nasazen do velkovýroby nakonec vůbec nebudeDOC_ZENITH píše:Já jsem to řikal už před lety (když bylo jasné jakej je 10nm epic fail), že se nakonec možná vůbec žádné mass produkce nedočkáme, má slova stále platí a to se blíží konec r 2020
Hlavně ice-lake už je z dnešního pohledu dost zastaralej, měl to bejt jen vesměs shrink SK-X, rozdíly asi jako Haswell-Broadwell. Takže i kdyby vyšel tak to bude "meh" produkt.
