AMD AM5 Platform Launches In Three PCIe Gen 5.0 Ready Chipset Flavors: X670E For Extreme, X670 For Enthusiasts, B650 For Mainstream Motherboards

AMD has also announced its brand new AM5 platform which will feature support for the Ryzen 7000 Desktop CPUs and include the X670E, X670 & B650 chipset-based motherboards.

AMD X670E, X670 & B650 Chipsets To Enable The Next-Gen PCIe Gen 5.0 Ecosystem For Ryzen 7000 CPU-Ready Motherboards

The AMD Ryzen 7000 CPUs will be migrating to a new home known as AM5, the successor to the long-lasting AM4 platform. It marks a fresh start for the Ryzen Desktop family and as such, existing Ryzen CPUs starting with Ryzen 1000 & all the way up to Ryzen 5000 won't be supported by the new platform we will tell you why it is so.

The AM5 platform will first and foremost feature the brand new LGA 1718 socket. That's correct, AMD isn't going the PGA (Pin Grid Array) route anymore and now focusing on LGA (Land Grid Array), similar to what Intel uses on its existing desktop processors. The main reason to go LGA is due to the addition of enhanced and next-gen features such as PCIe Gen 5, DDR5, etc that we will get to see on the AM5 platform. The socket has a single latch & gone are the days of worrying about pins underneath your precious processors.

AMD AM5 Feature Set: X670E, X670 & B650 Launching This Fall

In terms of features, the AM5 platform will initially support AMD's Ryzen 7000 'Zen 4' Desktop CPUs and extend that support to future Ryzen CPUs and APUs. The platform offers DDR5-5200 (JEDEC) memory support, up to 24 PCIe lanes (Gen 5 standard), increased NVMe 4.0, and USB 3.2 I/O lanes & we have also heard chatter about native USB 4.0 support which will be a game-changer.

A new feature called EXPO (AMD Extended Profiles for overclocking) will allow enhanced DDR5 memory OC on the new platform, similar to Intel's XMP. It has been a rough road for AM4 to offer decent DDR4 OC capabilities but that has more or less been sorted out by now, we can only expect DDR5 to have a much better OC and compatibility experience compared to DDR4 on AM4 platforms. Furthermore, it looks like the platform will only be DDR5 compatible and we won't see DDR4 options as we do on Intel's existing platform. But with DDR5 prices and availability improving, that won't be that big of a deal for most high-end consumers for who AMD will be aiming first.

AMD AM5 Platform Block Diagram:

The AM5 compliant AMD 600-series motherboards are currently being prepped up by the board makers, The 600-series lineup will initially consist of three chipsets, the X670E, X670, and B650. In terms of features, the X670E (Extreme) is designed for the higher-echelon of motherboards with unparalleled capabilities, and extreme overclocking, and will have PCIe 5.0 support for both GPU and storage. The X670 motherboards will be very similar in offering enthusiast-level overclocking but PCIe Gen 5.0 support for storage and graphics will depend on manufacturers. It is likely that some board makers will go to cost-effective route and enable PCIe 5.0 support only for the GPU while keeping storage limited to PCIe 4.0. Both X670 chipsets will come in a dual-PCH solution on the motherboard to allow for the increased I/O for the next-gen platform.


Finally, there's the B650 chipset which will be aimed as a mainstream motherboard solution and will only come with PCIe 5.0 support for the storage devices. The B650 motherboards will be the successor to the B550 motherboards and come in a similar price range. Compared to the X670/E offerings, the B650 chipset will come in a single PCH design. The motherboards will carry support for RDNA 2 iGPU too which will be featured on Ryzen 7000 'Raphael' CPUs and offer both HDMI / DP outputs.

One of the highlighted features of the AMD AM5 600-series platform is SAS or Smart Access Storage. This technology will enable GPU decompression with supported Microsoft DirectStorage games. Although there aren't many of those out there yet but expect industry-wide support for this on newer platforms.

SmartAccess Storage gets you out of the load screen and into your gameplay

Traditional game loading takes a significant amount of compute power to decompress the game’s data, requiring the CPU to do the decompression and data transfer, which introduces latency and takes up considerable system resources.

To help bypass these bottlenecks, AMD has created SmartAccess Storage, a suite of technologies supporting Microsoft DirectStorage that utilizes Smart Access Memory with new AMD platform technologies along with Radeon GPU asset decompression to improve both game load times and texture streaming
