Por exemplo, cada Chipset ligar ao Switch Pci-Ex via 4 Lanes (4 Lanes X 2 = 8 Lanes) e depois a ligação do Switch para o CPU ser só de 4 Lanes, em vez de 8, se os 2 Chipsets se ligassem directamente ao CPU. Além disso, toda a comunicação Chipset <-> CPU e Chipset <-> Chipset passaria pelo Switch Pci-Ex.O Super IO conectava num dos chipsets, embora é algo grande. Mas para que teria um PLX?
7600x , 7800x , 7900x e 7950x brevemente chegar ao novo am5. Tdp 170w com iGPU e DDR 5 e pciex 5 e nvme 5.
Gostei de ter finalmente 2 type-c. Já devia ser norma nas mid end vir 2 type-c e high end vir 3 ou mesmo 4.
3 USB vindo do CPU e 5 portas USB vindo de um dos chips, o segundo deve focar-se em expandir PCIE lanes.
Talvez com B-650 não tenhamos mais que 5/6 USB externas, mas é mais que suficiente ihmo.
In terms of performance, AMD is claiming its Zen4 core architecture will offer over 15% single-thread uplift (sadly we do not have the footnotes explaining what is being compared here), 2X bigger (1MB) L2 cache per core and Max Boost over 5 GHz.
The 600-series motherboards will offer up to 24 PCIe Gen5 lanes for storage and graphics, up to 14 SuperSpeed USB 20 Gbps (TypeC), WiFI-E6 support with DBS/Bluetooth Low Energy 5.2. Interestingly. AMD also revealed 600-series motherboards will be equipped with up to four HDMI 2.1 and DisplayPort 2 outputs.
https://videocardz.com/newz/amd-rev...-b650-chipsets-for-first-gen-am5-motherboardsAMD also confirms its new AM5 platform supports a new technology called SmartAccess Storage. We have revealed those plans a few weeks ago, and we were right in our predictions. This technology adds AMD platform technology and GPU decompression for Microsoft DirectStorage Enabled Games.
The AMD 600-series chipsets for AM5 are known as Promontory 21 (PROM21), and come in 3 configurations:
- Low-end, presumably A620, with a single defeatured PROM21
- Mid-range, known as B650, with a single PROM21
- High-end, known as X670, with dual PROM21 chipsets on the motherboard
Here are the specifications of a single PROM21 chipset (B650):
- 19 x 19 mm FCBGA package
- Maximum Power ~7W
- One PCIe 4.0 x4 Uplink to host
- Two PCIe 4.0 x4 downlink controllers (Total 8 Lanes)
- Four PCIe 3.0 x1 / SATAIII 6 Gbps flexible ports (4L PCIe or 2L PCIe + 2x SATA or 4x SATA)
- Six USB 3.2 Gen 2 10 Gbps ports (Two of the ports can be fused to form one USB 3.2 Gen 2x2 20Gbps port, with four remaining 10Gbps USB ports)
- Up to 6 additional USB 2.0 ports
For the A-class chipset, one PCIe 4.0 x4 downlink is disabled
For a typical motherboard with 4x SATA ports, B650 can support one PCIe 4.0 x4 M.2 NVMe SSD, while the A-class chipset supports none. The remaining PCIe 4.0 lanes are used for WiFi, 2.5G Ethernet and PCIe x1 expansion slots.
The X670 boards have their daisy-chained chipsets linked with PCIe 4.0 x4.
Thus, the specifications of a dual PROM21 daisy-chained board (X670) are as follows:
- Two 19 x 19 mm FCBGA packages
- Maximum Power ~7W x 2
- One PCIe 4.0 x4 Uplink to host
- Three PCIe 4.0 x4 downlink controllers (Total 12 Lanes)
- Eight PCIe 3.0 x1 / SATAIII 6 Gbps flexible ports (4L PCIe + 4x SATA or 2L PCIe + 6x SATA)
- Twelve USB 3.2 Gen 2 10 Gbps ports (Four of the ports can be fused to form Two USB 3.2 Gen 2x2 20Gbps ports, with eight remaining 10Gbps USB ports)
- Up to 12 additional USB 2.0 ports
Additionally, there is plenty of I/O directly from the CPU:
- One PCIe x16 slot for graphics (or bifurcated to two x8 slots)
- One PCIe x4 slot for M.2 NVMe SSD
- One PCIe x4 link for discrete USB4 controller (Maple Ridge JHL8540 or ASMedia ASM4242) or M.2 NVMe SSD
- One PCIe 4.0 x4 for chipset downlink
- Three combo USB-C ports supporting USB3.2 Gen 2 10Gbps and DisplayPort 2.0 UHBR10 Alt Mode (each combo port can be split into discrete DP and USB 2.0 Type-A)
- One additional dedicated display output (DP 2.0 UHBR10 or HDMI 2.1 Fixed Rate Link or eDP)
- One USB 3.2 Gen 2 10Gbps port with BIOS flash capability
- One USB 2.0 port with SecureBIO support for Windows Hello capability
- SPI/eSPI, GPIO, HD Audio
“X670E“ branded motherboards will require the primary PCIe and M.2 slots to support PCIe 5.0 linkrate. The chipset itself is identical to X670.
https://angstronomics.substack.com/p/site-launch-exclusive-all-the-juicyFor AM5, there was also the intention to dual-source these chipsets from 2 different 3rd party suppliers, namely ASMedia and MediaTek. However, we note that more recent developments have exclusively focused on validation using ASMedia silicon, and are unsure when Mediatek will supply chipsets, if at all.
