• repost Eddwardoveho príspevku z iného fóra ... snáď sa nenahnevá, aby aj tu bolo pekne spracované jeho info

Vsetko ohladom novej architektury potom smerovat sem.
Tema sa netyka moznych 10-jadrovych Comet Lake (Coffee Lake refresh refresh) procesorov.

Intel 10nm Sunny Cove ’10th Gen Ice Lake’ ES CPU Single-Core Performance Leaks Out, On Par With A 5.3 GHz 9700K at Just 3.7 GHz

Super. Kto cakal na Ryzen moze cakat na Intel.

Nez to bude na trhu, tak sa asi vyplati kupit ten Ryzen

Moc by som tomu ale neveril. Z 3.7 GHz na 5.3 je to narast 43%, to je naozaj neuveritelne, aby spravili taky obrovsky posun vo vykone.

[Leon]

Nieco som nepochopil? Ved tam pisu ze vykon na 3.7ghz je cca rovnaky ako ma 5.3ghz 9700k-a. Ake 43 percenta? Sunny vobec nemusi mat 5 ghz +-. Dokonca asi urcite mat ani nebude, uz dlho sa predpoklada ze nova arch kvoli tym problemom nebude mat vysoke frekvencie.

[M1ch4l]

z 3.7 GHz na 5.3 GHz je to 43% narast frekvencie, t.j. tolko sunny cove straca co do frekvencie. Takze aby tie cipy mali rovnaky vykon na takto rozdielnych frekvenciach, musel by sunny cove tych 43% dohnat niekde inde (IPC, latencie, ...). A hovorim, ze je to privela.

Intel začal dodávat 10nm procesory Ice Lake

[Leon]

V anandtechu zmerali výkon a IPC je cca 13 až 18 percent nad Skylake

https://www.anandtech.com/print/14664/t ... -lake-10nm

Vo výsledku to ale nakoniec bude možno úplne inak kvôli frekvenciám. ľudia dostanú tak 3 percentá celkového výkonu ako doteraz a dovidenia

This graph shows the single thread performance of Skylake and beyond, compared to 5th Gen Broadwell hardware. 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.

Zdá sa, že AMD bude fakt na koni nejakú dobu.

Ice Lake v prvních benchmarcích, jak je na tom Sunny Cove a grafický výkon?
