Intel Starts Qualification of Ice Lake CPUs, Raises 10nm Volume Expectation for 2019

Leta 2019 lahko torej pričakujemo le Ice Lake-U:

Intel's Ice Lake-U is a quad-core processor based on the codenamed Sunny Cove microarchitecture. Among other notable features, on the CPU side of matters Ice Lake-U supports VNNI and Cryptographic ISA instructions, as well as Intel's long, long awaited support for LPDDR4X memory. Meanwhile on the GPU side of matters, this is the first chip to integrate Intel's Gen11 iGPU, which with up to 64 execution units, promises a big step up in performance. The CPU will be paired with a chipset natively supporting Thunderbolt 3, 802.11ax Wi-Fi, and a number of other innovations. The whole Ice Lake-U package is expected to have a TDP of 15 W, so the product will be able to address thin-and-light and mainstream laptops.

Ne le, da o desktop procesorjih ni govora, še procesorje za laptope načrtujejo v zelo omejenem razredu, pod 15W. Gre torej za logično nadaljevanje Core i3-8121U - baby steps, ne 10nm revolucija.

Ice-Lake-SP Xeons in 2020

As for 10 nm ramp in general, Intel is only talking about producing its relatively small Ice Lake-U processors in volumes this year, which is the company's typical way of ramping up a new node. When it comes to their larger Ice Lake-SP server parts, Intel expects to launch those 10 nm Xeon products in 2020. The company says that its Ice Lake-SP CPUs will be available in less than 12 months after its Ice Lake-U products hit the market. In fact, Intel has even advised investors to expect 10 nm Xeons to arrive "rather sooner than later" in 2020, which would imply something earlier than Q4'2020.

Medtem ko procesorje za strežnike napovedujejo "konec 2020 ali prej", pa o desktopu niti besedice. Po logiki bi seveda sledil kmalu za procesorji za prenosnike, a Intel še preostega laptop programa (nad 15W) ni napovedal...

Lenovo in Dell pa sta medtem že leakala, da bosta že na Computexu pokazala laptope z Ice Lake-U:


New Dell XPS with Ice Lake confirmed and we'll get our first proper look this summer

Nekaj smo že videli.

Me zanima, če je bil Sunny Cove oz. Ice Lake zakoličen že praktično pred leti - pred odkritjem vseh varnostnih pomanjkljivosti v Intel procesorjih, glede na to da je roadmap, pokazan na Intel architecture day lanskega decembra "Security Features" pripisal šele arhitekturam, ki Sunny Covu sledijo...

Vprašanje tudi, kako realističen je ta roadmap - ena arhitektura od avgusta 2015 do decembra 2019 (Skylake), nato pa vsako leto naprej nova? Verjamem, da jih imajo "na zalogo" zaradi zaostajanja 10 nm procesa, in da bi bilo preskakovanje izdelane arhitekture metanje denarja stran, a se mi vseeno ne zdi preveč realistično, sploh glede na napovedi pičasnega vpeljevanja Ice Lake skozi celo naslednje leto...

Intel zadnje čase na veliko natolcuje.
Hkrati pa o marsi čem molči.

Ranljivosti, o katerih si govoril, so že ene take stvari.

Dejansko bodo pravi Intel procesorji, ki bi jih človek kupil, prišli čez par let. Ko se bo vse skupaj izzvenelo (proizvodni proces, krpanje ranljivosti).

Do takrat je pa, vsa zame, vse kupaj en "Fail cove".

Sunny cove?

Jup. Imaš na Anandtech.

Če misliš Intel Core i3-8121U, ta ni Sunny Cove oz. Ice Lake, ampak Cannon Lake, ki je le Skylake + nekah ukazov na 10nm (na pol delujoč in s slabšo učinkovitostjo perf / watt kot na 14 nm, razen dodanih novih ukazov).

uspeli so 5.7 Ghz z amd kartico ter porabi 1500W https://www.tomshardware.com/reviews/ov...

So oz. sedaj Ice za laptope z 15W TDP.

Večji problem je desktop.

Cannon Lake 10 nm ni isto kot Sunny Cove oz. Ice Lake - medtem ko je Cannon Lake praktično Skylake z ekstra AVX-512 in še nekaterimi drugimi dodanimi ukazi, pa je Sunny Cove kar velika sprememba:

On the back end of the microarchitecture design, Intel has done several things including increasing cache sizes, making the execution of the core wider, increasing L1 store bandwidth, and other things.



Starting with the cache improvements, the Sunny Cove core back end has a 48 KB L1 Data cache, upgraded from 32 KB. Normally cache misses decrease by a factor of a square root of the proportional size when the cache is increased, so in this case we should expect a 22% reduction in L1-Data cache misses. We are told that the L2 cache size has also been increased in both the Core and Xeon variants of Sunny Cove (256 KB and 1 MB respectively), although to exactly what size will be revealed at a later date.

While not back-end, the micro-op (uOp) cache has increased from a 2048-entry design, although exactly to what Intel is not saying at this point. The second level TLB size has also increased, which will help with machine address translation of recent addresses - normally this is increased when more lookups need to be kept and stored, which means that Intel identified a number of use cases where recent addresses had been evicted shortly before being needed



From the diagram we can see some other changes, such as the increase in execution ports from eight to ten, allowing more instructions to come out of the schedulers at one time. Port 4 and Port 9 is linked to a cycling data store, doubling that bandwidth, but also the AGU store capabilities have doubled, for which the increased L1-D size will help. Previously on Skylake there was a potential bottleneck when all three AGUs could attempt a store, however only enough bandwidth was present for one per clock cycle. Load performance is unaffected. There is also an allocation increase, moving from four to five. This means that the dispatch out of the reorder buffer can now hit five instructions per cycle, rather than four - however given that the ops/cycle out of the Skylake decoders and uOp cache was four-to-five (depending on certain factors), it will be interesting to see how the front end has changed as a result.

There are also substantial changes in the execution ports between Skylake and Sunny Cove, which is best represented in a diagram and a table:



...

For Sunny Cove, there is also built-in support for larger memory capacities. The paging table for main memory is now a five layer design, up from four layers, supporting a Linear Address space up to 57 bits and a physical address space up to 52 bits. This means, according to Intel, that the server processors could theoretically support 4 TB of memory per socket. We will see Sunny Cove hit the market in the server space with Ice Lake-SP in 2020 according to Intel's previous Xeon roadmaps. For security, Sunny Cove has access to Multi-Key Total Memory Encryption, and User Mode Instruction Prevention.

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. There is only enough to whet the appetite. Intel wants you (and me) to come back for more in 2019.


Medtem pa pri Intelu:

Intel's stock on track for biggest one-day drop since Sept. 29, 2008

This afternoon, Intel announced their earnings for Q1 of their 2019 fiscal year. Revenue for the first quarter came in at $16.1 billion, which is flat compared to Q1 2018, but margins were down 4% to 56.6%. Due to this, operating income was down 7% to $4.2 billion, and net income was down 11% to $4.0 billion.

Although Intel invested some additional $1.5 billion to boost its 14 nm fab output last year, it looks like its supply problems are not going to be solved until the second half of this year. The company admitted on Thursday during its earnings conference call that supply challenges will persist throughout the third quarter.

"We have increased capacity to improve our position in the second half, although product mix will continue to be a challenge in the third quarter as our teams align available supply with customer demand," said Robert Swan, CEO of Intel.

Padec vrednosti delnice je predvsem zaradi tega, Intelove napovedi o padcu prihodka tako za naslednje četrtletje kot tudi za celotno leto 2019:

Jah tega ne vemo, in še lep čas ne bomo vedeli - sploh zgleda za desktop.

Leak Intel roadmapa za prenosnike s Tweakers.net seveda ni potrjen, a se zaenkrat sklada z Intelovimi uradnimi izjavami.

Potrditev verjetnosti leaka je tudi omemba "omejene izdaje" Ice Lake-U in Ice Lake-Y procesorjev za drugo in tretje letošnje četrtletje - tako Dell kot Lenovo sta leakala, da pripravljata omejene serije prenosnikov nizkih moči, ki bodo predstavljene na Computexu - na voljo pa verjetno še pol leta ne ali pa v izjemno majhnih količinah, gre za miritev vlagateljev v stilu Core i3-8121U, 10 nm procesorja iz decembra 2017.

Semiaccurate je šel v svojih napovedih še korak dlje:

Leaked roadmap shows Intel's 10nm woes

Oni so že oktobra lani napovedovali, da Intelov 10 nm proces sploh ne bo deloval. Vmes so napoved sicer popravili na "bo deloval, ampak šele v drugi ali tretji iteraciji". Tweakers.net roadmap to dokaj podpira - zmogljivejše serije laptop procesorjev so še v celotnem letu 2020 napovedane na 14 nm!

Kar tudi nekako izključuje prihod Ice Lake desktop procesorjev kadarkoli kmalu po zadnjem četrtletju 2019, kot so do sedaj mnogi po tihem upali. Za vse prenosnike nad 28 W se bodo še celo naslednje leto uporabljali 14 nm procesorji, Coffee Lake H refresh, in po koncu 2019 še Comet Lake H 8 in 10 jedrniki. Za nižje zmogljivosti pa v drugem četrtletju 2020 pridejo še 10 nm Tiger Lake 4 - jedrniki, in kasneje 4 in 6 - jedrni Rocket lake s 14 nm CPU in 10 nm GPU.

Torej napovedi, da bo AMDjev Ryzen 3000 7 nm užival le kako četrtletje ali dva vakuuma pred prihodom Ice Lake desktop 10 nm procesorjev ne zgledajo prav verjetne...

Kaže, da je prehod na 10nm za Intel problematičen plus kaže, da je tudi sekanje ovinkov udarilo nazaj

Si si, glede na to da intel TR primerja z 2x drazjim procom, ok sej i9 primerjate tudi s skoraj 2x drazjim procom..
No koliko € na fps si pa bolsi ce vzames amd.
In kot smo rekli se gres 144FPS gaming , potem se pozna da na enmu si na low na drugem pa medium...

A tega trola sploh kdo resno jemlje?

Bodo z 7nm ryznom tam tam ves ta čas, škoda, da so imeli tak naskok.

Vmes je še 6nm.

V bistvu je 7nm+

O cem to ti?

Malo sarkazma, 7nm AMD GPU vs xx nm Nvida

Mogoce jih sreca pamet in bodo malce bolj resno zasnovali tudi prihodnjo generacijo GPUjev oz. mogoce si bodo lahko to financno privoscili.
Itak pa je problem, ce je na svetu veliko idiotov, ki bodo se vedno kupili precenjen GTX 1650, cetudi za isto ceno dobijo BISTVENO hitrejsi RX 580.

Slabe novice za intel na desktopu.
