Processador AMD ZEN3 (Ryzen 5000 series)

Agradeço a indicação. Eu estava a referir-me a dois kits de 2x16GB, portanto 64GB ao todo. Cada kit de 2x16GB 4000 Mhz CL17 a 320€.

Para quem quer ter o dito bolo e comê-lo, ou seja, 64GB a 4000 Mhz ou mais, ainda tem um custo proibitivo.

É o dobro do preço por mais 400 Mhz e CL17, comparando com os 64GB 3600 CL16 que eu tinha visto.

Espero que estes Ryzen não necessitem disto tudo para valer a pena...

Exacto... é que 4000MHz é porreiro para quem colocar por exemplo 16GB. É caro, verdade, mas fazível.. Trocar os 64 3200 por 4000 já dói mais..

É que para eu trocar os meus 64GB para 4000MHz iria ficar a pensar, porque iria gastar sensivelmente o mesmo para meter 128GB a 3600.

E na realidade, não preciso de nenhum dos dois face aos 64GB 3200MHz.. Não iria ter vantagem absolutamente nenhuma.

Independentemente de tudo, é aguardar para ver o que dizem quando saírem :)
 
Fora que 4 módulos e mais stress pro controlador de memoria, pode nao ser possivel mesmo com kits que de 4000.

Tive aqui a pensar, saiu leaks que o Rocket Lake pode ter all core de 5 ghz com boost de 5.5. Juntando o ganho de IPC vai destruir o zen3 em gaming, já que novamente ficamos com um delta de 600 a 800 mhz. Embora o rocket lake nao deve ter IPC maior, ja que o zen3 aparenta superar até o Tiger Lake.

Será que o "Warhol" será a resposta da AMD a "cozinhar" para bater o Rocket Lake em gaming? Eu diria que é um core monolitico de 8 cores para diminuir latências e ter clocks maiores.

A AMD pode introduzir isto como os 5000XT e mantendo os outros em MCM para diferenciar e ser gama mais acessível.
 
Coloquem Sal, mas andam uns Eng. Sample do 5950X, com OC a 6 Ghz, no Geekbench 5.................a correr MacOS. :D

Estive a ler na diagonal a entrevista ao "Mestre do Papel", no Anandtech e tem lá algumas coisas interessantes.

Zen3 usa os mesmos 7nm do Zen2:
IC: Speaking to that process node, TSMC’s 7nm as you said: we’ve specifically been told that it is this sort of minor process update that was used for Ryzen 3000XT. Are there any additional benefits that Ryzen 5000 is getting through the manufacturing process that perhaps we are not aware of?

MP: It is in fact the core is in the same 7nm node, meaning that the process design kit [the PDK] is the same. So if you look at the transistors, they have the same design guidelines from the fab. What happens of course in any semiconductor fabrication node is that they are able to make adjustments in the manufacturing process so that of course is what they’ve done, for yield improvements and such. For every quarter, the process variation is reduced over time. When you hear ‘minor variations’ of 7nm, that is what is being referred to.

Binning:
IC: With AMD and Intel, we’re now seeing both companies binning the silicon from the fabs to within an inch of its maximum - leaving very little overclocking headroom just so users have that peak performance straight out of the box. From your perspective how do features such as the Precision Boost Overdrive, where frequencies go above the stated range on the box - how do features like that evolve or do they just slowly disappear as binning optimization and knowledge increases over time?

MP: Of course our goal is to maximize what we support with our maximum boost frequency. With Zen 3 we do increase that to 4.9 GHz. We’re always focused on improving our binning - the way you should think about it is [that] we’ll always have the best boost frequency that we can provide, and it is tested across the full gamut of workloads. Our test suite tries to cover literally every type of workload that we believe our customers would be able to run on our CPU. But end-users are very smart, and they might have a segment of those applications, and our thought is that we will continue to provide overclocking so that the enthusiast that really understands their workloads and may have a workload that gives them an opportunity to run even faster given the unique nature of what they are interested in, of what they’re running, and we want to give them that flexibility.

Zen3 é um redisign do Zen:
IC: Zen 3 is now the third major microarchitectural iteration of the Zen family, and we have seen roadmaps that talk about Zen 4, and potentially even Zen 5. Jim Keller has famously said that iterating on a design is key to getting that low hanging fruit, but at some point you have to start from scratch on the base design. Given the timeline from Bulldozer to Zen, and now we are 3-4 years into Zen and the third generation. Can you discuss how AMD approaches these next iterations of Zen while also thinking about that the next big ground-up redesign?

MP: Zen 3 is in fact that redesign. It is part of the Zen family, so we didn’t change, I’ll call it, the implementation approach at 100000 feet. If you were flying over the landscape you can say we’re still in the same territory, but as you drop down as you look at the implementation and literally across all of our execution units, Zen 3 is not a derivative design. Zen 3 is redesigned to deliver maximum performance gain while staying in the same semiconductor node as its predecessor.

O ISA não interessa a nível de performance:
IC: While the x86 market for both client and enterprise is very competitive, there is increasing pressure from the Arm ecosystem in both markets, it’s hard to deny. At present, Arm’s own Neoverse V1 designs are promising a near-x86 level of IPC, and subsequent 30% year-on-year architectural uplift, at a fraction of the power that x86 runs at. While AMD’s goals so far have been achieving peak performance, like in Zen 3, but how does AMD intend to combat non x86 competition, especially as they are starting to promise in their roadmaps more and more performance?

MP: We won’t let our foot of the gas pedal in terms of performance. It’s not about ISA (instruction set architecture) - in any ISA once you set your sight on high performance you’re going to be adding transistors to be able to achieve that performance. There are some differences between one ISA and another, but that’s not fundamental - we chose x86 for our designs because of the vast software install base, the vast toolchain out there, and so it is x86 that we chose to optimize for performance. That gives us the fastest path to adoption in the industry. We have historically have lived in nothing but a competitive environment - we don’t expect that to change going forward. Our view is very simply that the best defense is in fact a strong offence - we’re not letting up!

Alegadamente, os SKUs dos APUs Mobile de 15 W, da Série 5000:
3CpFS5u.png


Algumas notas. Metade são "Lucienne" usando Zen2 e a outra metade é "Cezanne" com Zen3. Nada confuso portanto........
Os baseados no Zen2 vão dos 4 aos 8 MB de L3. Os baseados no Zen3 podem ter 8, 12 e 16 MB de L3. Isto é, os APUs Zen3 têm no Chip o dobro da Cache L3 dos APUs baseados no Zen2.
Os 2 modelos têm 8 CUs Vega. Nada sobre estes CUs Vega são iguais entre as versões Zen e Zen3.
Parece que todos os SKUs vão ter SMT activo.

Não percebo como pode haver tanta incompetência a dar nomes a CPUs.

Eu percebo que estejam a tentar escoar os restos dos zen2, mas isto não ajuda em nada a ficarem bem na fotografia.

Já do lado da Intel a salganhada de nomenclatura que lá vai na gama de portáteis é medonha, é quase preciso ter uma folha ao lado a indicar o que significa cada número.
Ridiculo!
 
Man, nem os 4000 se tem direito e agora vem esta salganhada.

E não esquecer da cena de 1 x 2 CCDs.

Este Cezzane em socket AM4 é capaz de ser um brinquedo muito bom se vier com 16 MB L3 unificado, humm
 
Que raio, afinal sempre eram verdadeiros os rumores?
E a acreditar nos rumores, daqui a uns meses devem sair os Van Gogh para TDP semelhante (7 a 18), com Zen3 + RDNA2 :freak3:
 
Boa tarde

Novidades sobre o Ryzen 5 5600X.

AMD Ryzen 5 5600X Benchmarked, Conquers Intel Core i5-10600K

5ymSgl5RQvJKTWOw.jpg


In the test results, the AMD Ryzen 5 5600X CPU has scored Processor Arithmetic and Processor Multi-Media scores of 255.22 GOPS and 904.38 Mpix/s. These scores are not much on their own until we compare them to some of the Intel offerings. When compared to the Intel Core i5-10600K CPU, which is likely its targeted competing category, it scores 224.07 GOPS and 662.33 Mpix/s for Processor Arithmetic and Processor Multi-Media tests respectively. This puts the AMD CPU ahead 13.9% and 36.5% in these tests, indicating the possibility of Zen 3. Another important note here is the thermal headroom both of these CPUs run. While the Intel model is constrained withing 125 W TDP, the AMD model runs at just 65 W TDP. This could be an indication of the efficiency that these new processors harness.

Cumprimentos
 
Última edição:
Não percebo como pode haver tanta incompetência a dar nomes a CPUs.

Alguém na AMD, na parte de "Branding", está a pensar que é um Génio por colocar Zen2 misturados com Zen3 nos 5000 e assim "despacha-los" de forma mais rápida. Provavelmente até tem razão.
A parte negativa é que a AMD não precisa de "despachar" os APUs Zen2, mesmo depois do lançamento dos APUs Zen3, porque eles não têm qualquer problema. O problema dos APUs Zen2 é mesmo ser complicado arranja-los em Desktop e Laptop.
A outra parte negativa é que, um cliente, se um dia perceber a marosca e se sentir enganado, se calhar não vai querer comprar produtos da mesma marca.

Anyway......
