Ako su sa zen-om+ uspjeli izvući 3% ipc-a sa samo sitnijim izmjenama na arhitekturi, za očekivat je da će zen 3 donijeti veći napredak u odnosu na zen 2. Izmjene će biti osjetno veće, za početak memorijski kontroler migrirat s 12nm na 7nm+ što će podosta smanjiti dimenzije, potrošnju i osloboditi prostora za npr ugurati još l3 cache i drugih stvari, onda i same jezgre na 7nm+ proizvodni proces koji će biti dosta ispoliraniji, zreliji u odnosu na trenutnog pa možemo očekivat i oko 200 mhz veći takt i 20% više tranzistora, nešto kao prelazak s 14nm na 12nm, vjerojatno i bolje.

Tesko da ce IO dio maknuti s 12 nm, jos uvijek su vezani s GF pa im je isplativije raditi IO na 12 nm nego placati penale. Plus sto IO dio ne skalira dobro sa smanjivanjem nodea.

A i mislim da im još prostora ne treba, vjerujem da više neće povećavati broj jezgri, no to sam rekao i nakon 8 corea

Neka alternativna rješenja su moguća kod apu-a (već za zen 2) - npr. Da umjesto jednog core čipleta bude gpu, manji I/O die, nekakav hbm2 ili L4 Cache ili nešto...

DDR5 je valjda logična nadogradnja, PCIe 6 koji je najavljen, brijem još više jezgri jer će se TDP još malo smanjiti, bilo bi super kad bi uveli četverokanalnu memoriju u gaming klasu po niskim cijenama

The AMD Zen 5 core was*confirmed*to be in development by AMD a while ago in their slides during the Zen+ launch. It has once again been confirmed by David Suggs, who’s the chief architect for the AMD Zen 2 and Zen 5 microprocessor cores. AMD has teams within the CPU department who are working on different Zen cores in parallel. David, in particular, has been the Chief architect behind the AMD Zen 2 core which recently made its debut with the*Ryzen 3000 processors*and also, the upcoming Zen 5 cores.

...

The Zen 5 core which should launch in between 2022-2023 can be based on a further optimized 5nm process which would allow for significant performance uplifts. Since there are no more “+” within the Zen family (e.g. Zen+), we should expect noticeable upgrades that would further lift IPC along with improved chiplet interconnects. AMD’s Zen 5 core would mark another breakthrough for AMD by the time it launches while their*competition*would still be relying on their in-house 7nm node.

AMD 3rd Gen Threadripper Coming This October to Take on Intel's New HEDT Lineup?
Citiraj:
AMD is planning to surprise Intel by unveiling its 3rd generation Ryzen Threadripper HEDT (high-end desktop) processor lineup around the same time Intel launches its 10th generation Core "Cascade Lake-X" processor and the "Glacial Falls" HEDT platform, according to sources in the motherboard industry, speaking with DigiTimes. We're fairly sure the sources aren't referring to AMD's 16-core Ryzen 9 3950X processor, because it has already been announced and will be available in September. The 3rd generation Ryzen Threadripper will likely be a derivative of the company's "Rome" multi-chip module, and compatible with existing socket TR4 motherboards with a BIOS update, although a new chipset could also be launched to enable PCI-Express gen 4.0. AMD has the option to deploy up to 64 CPU cores across eight 7 nm "Zen 2" chiplets, while the 12 nm I/O controller die will be likely reconfigured for the HEDT platform with a monolithic 4-channel DDR4 memory interface and 64 PCIe gen 4.0 lanes. It's capable of 8 memory channels on the 2nd generation EPYC.

Ajde prestanite, kakve veze ima video o liku koji kenja 25min "Ja nisam htjeo radit više videje o AMD-u al mi moja duhovna zajdnica s discorda pomogla da prebolim krizu identiteta pa ću ipak raditi videje o AMD-u" ima veze s nadolazećim procesorima? HU ima patreona pa nikad nisu izbacilo pola videa na patreona a pola public na yotube, to je dick move. Zajebao je masno i kraj priče, otvorite temu i svaštari za njega i ostavite nas na miru.

Slažem se sa Sheby o tome da neki video o tome što će on raditi sa svojim kanalom nema mjesta u ovoj temi.

Da je slučajno tema u videu o nadolazećim cpu/socketima i sl. nebih imao ništa protiv (mada bi nekima i to smetalo). Jer budimo realni i da ispadne netočno većina linkova o nadolazećim stvarima su leakovi, "leakovi" i nagađanja, te naša vlastita trabunjanja. To je ipak on topic.

Za ove ostale stvari su ionko svi supscribeani koga zanima

x599 za threadripper razumijem, no ove X590 za AM4 mi ne drže vodu (videocardz iznosi teoriju prema kojoj je kao x570 zamišljen kao bez pci-e 4.0, a x590 sa, no očito nije ispalo tako, dok wccftech iznosi teoriju da je x590 možda neka limitirana serija uz R9 3950x)

Koliko znam AMD je imao plan da ima x570 i x590 ali su odustali od tog i sve ugradili u x570. Jedino gdje x590 ima smisla je ako bude imao vise pci-e staza. Ali je moguce da su ove Asus ploce bile samo prototipi prije nego je AMD odbacio x590.

AMD EPYC Rome 7742 battles Intel Xeon in benchmarks posted online
Citiraj:
If the recent benchmark postings are to be believed, the EPYC 7742 will have 64 cores and 128 threads and, therefore, would likely be the flagship model. The processor allegedly has up to 256MB of cache and comes with 225W. If the leaks are accurate, the 64-core monster will run at a 2.25 GHz base clock and 3.4 GHz boost clock. The deleted posting pitched the EPYC 7742 against AMD's own EPYC 7601 and Intel's existing Xeon Platinum 8280 and Xeon Gold 6138 chips. According to the test notes, the aforementioned processors were tested in both single-socket and dual-socket configurations on the Ubuntu 19.04 operating system with the latest Linux 5.2 kernel. The user also claimed to have applied all mitigations for each processor.
TL;DR - AMD za sutra sprema ubojice fazana.

AMD's biggest problem is going to be production capacity. Because they are going to sell every single piece of Rome silicon they spin.
Razlog zasto ima lošeg silicija i zašto je nestašica 3900X....sve dobro ode za Rim, Google, Twitter, Microsoft...samo neki od klijenata

So has AMD done the unthinkable? Beaten Intel by such a large margin that there is no contest? For now, based on our preliminary testing, that is the case. The launch of AMD's second generation EPYC processors is nothing short of historic, beating the competition by a large margin in almost every metric: performance, performance per watt and performance per dollar.

AMD EPYC 7002 Series Rome delivers a Knockout
Citiraj:
AMD is now engaged in an asymmetric attack against the legacy Intel Xeon architectures. Intel has a competitive response in its 2020 “Ice Lake” generation, but its 2nd Generation Intel Xeon Scalable chips released just four months ago are not competitive in many markets. This is all due to the 10nm process delays which pushed next-generation Intel Ice Lake out and therefore has the AMD EPYC 7002 competing against a legacy Xeon architecture. The world has certainly changed. AMD EPYC 7002 “Rome” now brings a better chiplet design. Intel is also not saying AMD “glued” together parts anymore. Instead, Intel is trying to catch up with the Intel Xeon Platinum 9200/ Cascade Lake-AP family gluing two pieces of silicon together and losing some functionality. Intel is also aggressively marketing its packaging technology advantages.
Citiraj:
On the AMD EPYC 7702P side, AMD is calling Intel that if it wants to be performance competitive, it needs to discount two Platinum 8280M’s by 83% plus the incremental cost of a dual-socket server versus a single-socket server.
This is a big deal.

Citiraj:
AMD specifically asked us not to use power consumption from the 2P test server with pre-production fan control firmware we used for our testing. We are also not allowed to name because Intel put pressure on the OEM who built it to have AMD not disclose this information, despite said OEM having their logo emblazoned all over the system. Yes, Intel is going to that level of competitive pressure on its industry partners ahead of AMD’s launch. In every dual-socket test, we are seeing the AMD EPYC 7742 out-perform the dual Intel Xeon Platinum 8280 configuration sometimes by ~2x, and yet the maximum power is lower.

Previše se taj intelov node spominje kao problem, to im dosta utječe na efikasnost, no veći je problem arhitektura tj. nepostojanje chiplet dizajna, jer s ovom ne mogu nikako pratiti core count, dok ovi povećavaju kao od šale, a i ovo što naprave je gro skuplje zbog ogromnog die size.

Taktike su i dalje iste, jer eto - ljudi ne bi skužili da nova EPYC 7002 serija troši i košta manje, dok istovremeno nudi više.

Mark Papermaster (AMD’s Chief Technology Officer) however said that the company both “Can’t let up” and “won’t let up” with its pursuit of performance.

“We are always working on the next designs while we are doing our current design,” Papermaster was highlighting the ‘leapfrogging design teams’ approach AMD uses for its engineering efforts. In a nutshell, there is an overall project manager which helps coordinate the efforts of the design teams.

But the teams work on different architectures and are not competing with each other, instead, they share and empowering each other’s ideas. So as Zen 2 is being worked on, they can share what they’re learning (such as the strengths and weaknesses of Zen 2) with the team designing Zen 3, so they can attempt to fix those issues the best they can.

Mark Papermaster also confirmed that Zen 3 is “right on track” for launch next year, and a slide was used to solidify this assertion. Zen 3’s design is complete, and Zen 4 is currently in the design phase.
This likely means that Zen 3 is going to start being tapped out, Engineer Sample processors created and then tested in preparation for the architectures release next year.

“We don’t stop there, we already have our engineers working on Zen 4,” he said. It’s fundamental for us to keep momentum in the industry. We have focused on showing the industry we have a roadmap that we can delivery to enterprise and data center as promised.”

“We know that’s a highly competitive environment we are in, but for us, it is personal. We will not let up, you have our commitment,” he concluded.

To put the new roadmap into context, this is the roadmap that AMD put out in the early part of 2018 when the original Ryzen was still current, and we were waiting on the release of the Ryzen 2000 series. Details are scarce for Zen 3, and virtually non-existence for Zen 4. We do know that Zen 3 for the AM4 platform basically represents the end of AMD’s backwards compatibility commitment. So, in theory, at least, Ryzen 4000 should still work on say an X370 motherboard (though we can guess without features such as the latest PCIe standards and so on).

There has been no shortage of other rumors for features such as SMT-4 for Zen 3, though whether this is either accurate or what line of processors would feature SMT-4 is… at best, questionable.

Zen 3 does use 7nm+, which means some of the layers use EUVL in the manufacturing process. In theory, at least, this should improve yields and offer around 15 percent better area scaling, as well as improving power consumption and performance. Performance is said to be about 10 percent better at same power consumption compared to the ‘vanilla’ 7nm process.

Regardless of all that, AMD is executing very well indeed, and with news Google, Dell, HPE and many other partners are jumping into the Rome ecosystem, AMD probably will have a pretty good future in the data center for at least the next few years.

"at the same power consumption". Znači ne mora značit da će uopće imati veći clock, nego će biti efikasniji. Vjerojatno će performance gain ići preko IPC

Ne vjerujem u neki porast clocka za zen3 nakon svega. No čak i da dođe do pada clocka činjenica je da će izbaciti brži cpu (znači vjerojatno isključivo ipc gain)
