Ma jok, "nova" arhitektura bazirana na skylakeu
Samo je i dalje pitanje 10nm, hoće li im uspjeti.

Ili stvarno imaju novi 10nm spreman ili budu dobar stari 14nm dodatno nasvirali, pa ko i svi ostali - jednostavno ga marketing označi kao 10nm i voljno.

Mada nadam se da sad uistinu imaju funkcionalnih 10nm za (masovnu) proizvodnju.

Sunny Cove (2019) is an improved architecture CPU in 10nm -- that'll be the downgraded but hopefully now working 10nm process, might be called 10+ (but it's really 10-...). Willow Cove (2020) is a further optimised Sunny Cove with process tweaks, presumably Intel will call this 10++ but it's based on the same process, it's certainly not 7nm. Golden Cove (2021) is another 10nm CPU with more features, and maybe (going by Intel strategy in the past) some more process tweaks, maybe this will be 10+++? Timescales for 7nm are (according to Intel) completely decoupled from 7nm; logically you'd expect the first 7nm CPUs to emerge in 2022 according to the above dates, but maybe if 7nm really does deliver on-time (unlike 10nm...) the later 10nm CPUs will get canned in favour of 7nm.

There have been various rumours about what Intel are doing to fix their 10nm yield problem, including going from 36nm to 40nm MMP and ditching SAQP for interconnect, removing cobalt for interconnect, and removing COAG (said to have been the reason they couldn't get any GPU yield on the i3-8121U). Whatever the exact truth is, there is bound to be some impact on density below the much-vaunted Intel numbers (probably now similar to or maybe even a bit lower than TSMC), and more to the point relayout of all custom IP (which Intel have a *lot* of) as well as new standard cell and RAM libraries which means a big delay -- normally fundamental layout changes to a process like this need re-characterisation of libraries and IP before products can be taped out. Best guess is that the "new" Intel 10nm process (and products made on it) will be at least a year behind TSMC 7nm even if things go well, which then puts it directly up against TSMC 7nm+ (partial EUV) which will be ~20% denser using the high-density process/libraries, and probably faster (at the same density) than Intel using high-speed process/libraries. Intel must be hoping that their promises of delivering their 7nm process on-time (whatever that means...) using a different team pay off, but it seems impossible that it will catch up with TSMC 5nm which will be in risk production in 2Q2019.

If Zen 2 can be pushed as high as 5GHz it's likely to be because AMD chose high-speed low-density libraries (e.g. 9-track 4-fin with DDB) instead of low-speed high-density ones (e.g. 6-track 2-fin with SDB), together with a performance-oriented metal stack (fewer minimum pitch layers, tapered width higher metal, thick top metal with MIM decoupling) instead of a density-oriented one (more fine-pitch metal, thinner higher metal) --- but all these are elements of the same basic 7nm process, the recipe you choose from the huge bag of ingredients is up to you. Intel would always have used high-performance options, TSMC used to introduce high-density ones first because that was their big customer base, but now they also see HPC/CPU as a priority so are making suitable process options available from the start.

Intel Xeon W-3175X zeigt sich zu Preisen ab 4.100 Euro - duplo skuplji od Threadripper 2990WX modela, a opet duplo jeftiniji od Xeon Platinum 8176.

Nema više šamaranja mrtvog magarca tj. skylake refreshiranja i 14nm. Sljedeći intel desktop bi trebao biti nova mikroarhitektura na 10nm, sad dali će se zvati ice lake ili sunny cove nebitno. Očekujem standardnih +5% ipc +/-, ali i pad clocka naspram coffee refresha

[The Exiled]

14nm možda više nema, ali Skylake (i derivati) budu i dalje poslužili kao temelj za dodatnu Sunny Cove optimizaciju. Obzirom da zapravo nisu pokazali ništa novo, već je sve još uvijek obavijeno 10nm misterijom, pitanje je na koju foru su došli ili dolaze iz sfušanog i neiskoristivog 10nm procesa, u ovaj "novi" 10nm s kojim budu daljnje tri-četiri godine plasirali sve svoje proizvode na tržište.

još par info o sunny cove-u : Intel Chief Core Architect on Spectre/Meltdown, Sunny Cove, & 10nm

Mora se priznati da Intelov marketing zna kaj radi:

Sunny Cove | Willow Cove | Golden Cove: to be very clear here, these are the codenames for the individual core microarchitecture, not the chip, which is an important departure from how Intel has previously done things.

Ko bi rekel, čisto da se dodatno zbuni sve i svakoga.

So where does this leave us in terms of Sunny Cove predicted performance compared to Skylake at a clock for clock level? Unfortunately we don’t have enough information.

OoO 5.0GHz+ all-Sunny-Cove-core CPU?

Intel confirmed that Ice Lake will be built using Sunny Cove cores. But Intel also showed off what they said was an Ice Lake Xeon 10nm processor and package.

Color me skeptical, but what was held up is likely either not ICL-SP or just silicon that doesn’t work.

Dakle, ni novinari koji su bili na tom druženju, na kraju dana još uvijek ne znaju ništa konkretno. Bilo bi za očekivati da će Intel, ako stvarno imaju "novih" 10nm svim okupljenima pokazati aposlutno sve, ne samo razvojne ploče za 15W Ice Lake U i svoju ARM big.LITTLE verziju. Tim više, jer kad Intel uistinu ima nove proizvode na novoj mikroarhitekturi i novom (ili poboljšanom) proizvodnom procesu onda to izgleda kao Sandy Bridge (1 - 2) ili Haswell predstavljanje, isto kao što je AMD napravil za Zen+ CES Tech Day. Nerijetko je Intel koristil IDF za najavu stvari koje su dolazile godinu-dvije kasnije, a sad ne žele dati izravan odgovor na pitanja oko "novog" 10nm procesa, ali hej 7nm samo što nije, jer je zapravo razvijan paralelno s prošlim, starim i propalim 10nm procesom, koji opet nije baš takav fijasko da ne bi poslužil za "novi i poboljšani" 10nm Sunny Cove i društvo.

Dabog da je sve kaj su rekli o tom novom 10nm procesu istina, u suprotnom...

[Smartic]

Ovo mi se čini ko da su sve požurili mjesec dana samo zbog Zen 2 leakova i polupripremljeno najavili sve i svašta umjesto na CESu.

[The Exiled]

Bome i to kaj veliš, a i Intel je u polupripremljeno modu od izlaska prve Ryzen generacije. Da nije, početkom 2019. bi tek čitali recenzije o Core i7-8700K. Nema jebene šanse da bi u međuvremenu sve ovo izašlo na vidjelo.
