Processador AMD ZEN2 7nm (ler primeiro post)

Já tinha mencionado umas 2 páginas atrás, a AYA Neo "handheld gaming console"

Aya Neo appears to be capable of offering 28-36 FPS throughout the demo featuring Cyberpunk 2077, the highly anticipated title that will launch on December 10th on next-gen consoles and PCs. The game settings were not shown, but they are probably set to a minimum (obviously do not expect ray tracing here). The video is not very good quality either, so we cant see how detailed the textures are in this demo.

The console features a 1280×800 screen, which is a standard resolution of most mid-range tablets. Aya Neo does not have any discrete GPU, hence all rendering takes place on the integrated Radeon Vega graphics. AMD Ryzen 5 4500 features 6 GPU cores clocked at 1500 MHz. This is not the top tier APU in the Renoir-U series and we are not quite sure why Aya opted for the cut-down model featuring 6 CPU cores and no SMT (but lack of hyper-threading might have no impact on gaming performance). The processor has a nominal TDP of 15W, but can be confirmed within the 10W to 15W range.

Ficarei muito surpreendido se eles não forem anunciados na CES, pelo menos os Zen2.
 
Relativamente ao 3500X e o 3600 qual é a diferente entre os dois?

Do que tenho visto não há diferenças tirando os clocks.

Tenho visto os preços a subir e ia fazer o upgrade a um PC para gaming, mas assim está complicado...

O 3500x tem 6 cores e 6 threads, o 3600 tem 6 cores e 12 threads e o turbo deste tem mais 100MHz.
 
First Tests: AMD’s Ryzen Threadripper Pro, New Muscle in Workstation CPUs

Threadripper Pro: A Lenovo Exclusive (for Now)
For its debut, the Pro chip is available exclusively in the Lenovo ThinkStation P620, a workstation tower that we are reviewing in parallel with this story. AMD says it will make the chip available to other workstation vendors after the exclusivity arrangement ends, though it did not provide a timeline for that.

The Ryzen Threadripper Pro also uses the new WRX80 chipset, which brings on a bunch of improvements over the TRX40 chipset. (TRX40 debuted to support third-generation Threadrippers.) The WRX80 supports up to 128 PCI Express 4.0 lanes, up from 88 for the Ryzen Threadripper and its TRX40 chipset. It also doubles the memory channels from four to eight and works exclusively with error correcting code (ECC) memory.

One last curiosity about the Ryzen Threadripper Pro is that it does not require Windows 10 Pro for Workstations, like some Intel Xeon chips do. Thanks to a licensing agreement between AMD and Microsoft, Ryzen Threadripper Pro systems can use straight Windows 10 Pro, which will help keep costs down. The arrangement makes sense, since Windows 10 Pro for Workstations supports technologies that Ryzen Threadripper Pro workstations will not use, such as multi-CPU implementations.

Tal como diz o artigo a "exclusividade" da Lenovo não deverá manter-se por muito tempo.

Curiosamente hoje a Videocardz publicou uma foto de uma Gigabyte WRX80

Gigabyte WRX80 SU8 supports up to AMD Ryzen Threadripper PRO 3995WX, which is a 64 core 280W CPU based on sWRX8 (4094) socket. Unlike the Threadripper non-PRO series, the WRX80 platform features 8-channel memory support.

The series also supports up to 128 PCIe lanes, a double of what the non-PRO series do. This might be important as this WRX80 motherboard features seven PCIe Gen 4 x16 slots.

Se maior parte do software IPMI já é mauzito, um feito pela Realtek deve ser um desastre :D

Tem melhorado e iniciativas como OpenBMC está a começar a dar os seus frutos. Ainda há uns dias a AMD fez uma apresentação sobre o seu suporte ao OpenBMC e começam a aparecer alguns modelos de algumas marcas a usar o OpenBMC.
No Software dos IPMIs, ainda se apanham muitos "cancros". Há pouco tempo reparei num, relativamente recente e com a ultima versão do software, que usava o Kernel 2.6.28...............Vá lá, já é uma sorte não ser o 2.4. :005:

As Lans da Realtek também estão substancialmente melhores. Os maiores problemas que tenho visto é com NICs antigas deles, muitas vezes usadas em IPMIs, que transformam um Switch numa árvore de natal.

Em relação ao TR Pro, há uma coisa que não percebo. Aquilo parece uma transformação de um 1 Epyc para 1 socket com clocks diferentes, no entanto o Epyc não usa Chipset. Eu vejo o cooler passivo do Chipset, na Board da Gigabyte, mas aquele Chipset faz exactamente o quê? 8 canais de memória não tem relação com o chipset. 128 Lanes Pci-Ex é igual ao Epyc, por isso suponho que vem tudo do CPU. O Chipset receberá umas lanes Pci-Ex, para umas portas SATA, Som e IO Legacy?
Neste tipo de plataformas, com aquela quantidade de Lanes Pci-Ex, parece-me sempre um desperdício terem chipset.

Já agora, essa board da Gigabyte é um pouco estranha. Parece uma mescla de Board para Servidores (A caixa diz "Server") e Workstations.


Há uns dias vi uma review à Gigabyte MZ-72 HB0, para o mercado de Servidores e pensei que com uma Gráfica, placa de Som e placas USB, dá uma bela "Mega Workstation" com Dual Epycs, visto que é uma Board Extended ATX:

Mesmo sendo Extended ATX, para colocarem 2 Sockets, fica mesmo ali no limite das dimensões da Board. :)
 
Hoje fui ao site da msi para ver se havia uma bios nova para a minha msi b450a pro max e estava lá uma bios beta com a designação de:
- Updated AMD AGESA ComboAm4v2PI 1.1.0.0 Patch D
- Support Re-size BAR function to enhance GPU performance.

Alguem sabe se esta função de BAR funciona com os cpu´s zen 2 da serie 3000? ou como ativar esta função?

" The requirement of this feature is pairing the AMD Radeon RX 6000 series graphics card with AMD Ryzen 5000 series desktop processor"

https://www.amd.com/en/technologies/smart-access-memory

Já se fala ficar disponível para placas Nvidia e Intel.
 
Há rumores que possa funcionar nas outras gerações de ryzen.

Inicialmente a amd indicava que era preciso uma b550 ou x570.
 
Última edição:
Já foi aqui mencionado. As gerações anteriores dos ryzen carecem de uma instrução especifica que é a maior responsável pelos ganhos com o SAM.

TechPowerUp notes that the new Ryzen 5000 CPUs are the only AMD series to integrate the PCIe physical layer feature called full-rate _pdep_u32/64, which allows processors to see the GPU’s entire video memory as a single addressable block instead of separate 256 MB apertures. It is true that Zen2 CPUs use the same IO die and PCIe controller as Zen3, but AMD SAM is actually controlled through a new ISA CPU instruction set. These specific instructions are only emulated in microcode using other similar instructions in the Zen2 and older cores, and this makes everything predating the new Ryzen 5000 essentially too slow to benefit from the performance uplift offered by SAM.

Mais uma review à Lenovo ThinkStation P620

AMD Threadripper Pro 3995WX Review: The Lenovo ThinkStation P620 Debut
The 3995WX serves as the head of AMD's new four-pronged Threadripper Pro lineup, which extends down to 12-core models, and all of the chips are currently exclusive to Lenovo's ThinkStation P620 workstations, at least for now. We have seen new unannounced WRX80 motherboards from ASUS and Gigabyte pop up over the last few weeks, so it is possible that we could eventually see Threadripper Pro products come to retail.
Threadripper Pro processors support 128 lanes of PCIe 4.0, but Lenovo doesn't use all of the lanes for this particular chassis – the P620 supports 80 PCIe 4.0 lanes for the PCIe slots, which leads the workstation segment.
https://www.tomshardware.com/news/amd-threadripper-pro-3995wx-review

Deduzo que as boards que estejam para ser lançadas façam uso do resto das lanes PCIe, falta saber é se os CPU estarão à venda no mercado (não OEM) ou não.

AMD Opens Up Threadripper Pro: Three New WRX80 Motherboards

Stepping out of its supposed 'exclusivity deal' with Lenovo, who had the first rights to Threadripper Pro in the ThinkStation P620, motherboard vendors have started showing off some of its WRX80 motherboard models designed for AMD's Ryzen Threadripper Pro processors. Some of the benefits of the new platform over standard Threadripper include eight-channel memory and up to 128 x PCIe 4.0 lanes, which is double that of the non-Pro variants. While this sounds like EPYC, it sits between the two with only 2 TB DRAM support. It's time to showcase what we know, including three new models based on the WRX80 chipset.

Ryzen%20Threadripper%20Pro%20Press%20Deck_7.9-page-010_575px.jpg

The AMD WRX80 chipset benefits from eight-channel memory for increased bandwidth when compared to quad-channel Threadrippers and dual-channel Ryzen configurations, with capacity for up to 2 TB when used with DDR4 LRDIMM memory. It also includes support for both ECC and non-ECC memory at DDR4-3200. The biggest jump in regards to specification compared to regular TR is in its PCIe support, with up to 128 PCIe 4.0 lanes available, which in turn increases the amount of PCIe slot real estate vendors can use.

Supermicro M12SWA-TF
M12SWA%20TF%20front2%201200_575px.jpg

It is E-ATX in size, which is fully utilized with an impressive six full-length PCIe 4.0 x16 slots. This includes support for two triple-slot or three dual-slot graphics cards, which will depend on the configuration a user opts for. For storage, the M12SWA-TF includes four SATA ports and four PCIe 4.0 x4 M.2 slots that include support for RAID 0, 1, 5, and 10 arrays. Supermicro has also incorporated two PCIe 4.0 U.2 slots, with support for just RAID 0 and 1 arrays. The M12SWA-TF also uses an ASpeed's 7th generation AST2600 BMC controller with one D-sub video output on the rear for physical IPMI access. (Ian: Oooh, AST2600 is new, isn't it?)

The board also includes support for up to five USB 3.2 G2 ports, with four Type-A and one Type-C, and five USB 3.2 G1 Type-A ports including a mixture of support on the rear panel and through internal headers. There's also two USB 2.0 ports available, with ten 4-pin fan headers, including two for CPU fans and eight for chassis fans. Supermicro is using Realtek's new and unannounced ALC4050 HD audio codec, with a secondary ALC1220 codec. Networking support includes two RJ45 ports, including one powered by an Aquantia AQC113C 10 GbE controller, with an Intel I120-AT Gigabit controller also allowing for IPMI access.

EDIT: do que percebi do comunicado da AMD, que tem declarações de um responsável da HPE deduzo que vá haver oferta de uma Workstation da HP.
 
Esta board e uma chapada nas mariquice de RGB e plásticos, mesmo de homem.

Bom, acho que usa todas as 128 lanes

6x pcie x16 = 96 lanes
4x m2 = 16 lanes

Logo ja temos 112 lanes, so sobrou 16, mas penso que tal como no WRX40, 8 lanes vai pro chipset... Se bem que nem precisava de chipset a plataforma...
 
A Supermicro vai ser vendida como workstation, mas também está disponível um kit para poder montar em rack.

The Supermicro AS-5014A-TT system is the workstation platform built around the M12SWA-TF motherboard.
Supermicro-AS-5014A-TT-Front-Three-Quarter.jpg

his is a standard workstation tower from Supermicro. We are told that there are both air-cooled as well as 360mm closed-loop liquid cooling options for the AMD Ryzen Threadripper Pro CPUs. At a system level, support for 256GB DIMMs gets us up to 2TB of memory supported although that is likely cost-prohibitive for many users. Still, if you need it, it is available and not currently available on the Lenovo ThinkStation P620.

We asked Supermicro and there is an available rackmount kit for this platform. That allows the system to be racked. The front-to-rear airflow of the CPU and DIMMs means that it should work well in a rackmount environment as well.
