$212 / $209 / $209 / $189It's been two years since the launch of the AMD AM5 motherboard platform and the 600-series motherboards. Since its launch, the platform has seen the launch of several CPUs in the Ryzen 7000, Ryzen 8000, and Ryzen 9000 family. While the 600-series motherboards provide great features & compatibility with newer Zen 5 CPUs, motherboard makers are always looking to enhance user experiences through the latest technologies, which is why AMD has introduced a new chipset line called 800-series.
The first wave of AMD 800-series motherboards (X870E & X870) hit shelves last year with the Ryzen 9000 series and now, the company has released the latest B850E & B850 options for mainstream PC builders. These motherboards provide brand-new designs and brand-new features that are sure to entice new AMD builders and older AM4 users into investing in a new motherboard for their gaming and content creation needs.
We received a load of motherboards from various manufacturers so let's start by taking a look at these updated designs. For this review, we will be testing out four ASRock B850 motherboards, the B850 RIPTIDE WIFI, the B850I Lightning WIFI, the B850 Steel Legend WIFI and the B850 Live Mixer WIFI.
The AMD AM5 Platform
The AMD AM4 platform has been the longest-running modern-day platform to date which was first introduced in 2017 & is very much alive and kicking in 2024. The company just recently launched new chips for the platform and it looks like it will stick around for a good while.
AMD is now launching its 2nd Generation AM5 platform under the new 800-series family. The lineup initially targeted high-end enthusiasts with the X870E and X870 chipsets but now, we're going to look at the budget segment with the B850E and B850 options.
The AMD B850 chipset will offer both Gen5 and Gen4 capabilities with Gen5 primarily being used for NVMe storage devices and Gen4 for graphics. The motherboard makers will have the option to dedicate the Gen5 lanes to a discrete graphics card if they want. The AM5 motherboards based on the AM5 chipset will also feature USB 3.2 (20 Gbps) support so no USB4 like the high-end options. Graphics will be handled in x16 (Gen4) or x8 (Gen5 or Gen4) configurations. The good thing is that B850 motherboards will support both memory and CPU overclocking and will be targeted at Intel's B760 family which mostly covers the $100-$200 US range.

The motherboards will feature support for DDR5-5600 MT/s memory speeds natively and over 8000 MT/s transfer rates on some of the high-end motherboards that we will be getting by the July timeframe.
The AMD B850 motherboards will feature the same Promontory 21 die minus the native USB4 support. They will carry Gen5 GPU support but Gen5 M.2 support will be optional. The B840 will be the entry-level option within the series with the older Promontory 19 die, which means you will get just Gen4 GPU/SSD support, no CPU overclocking and only memory overclock support. The B840 motherboards are going to be very affordable in terms of pricing so that will be competitive against sub-$200 US options from Intel.
AMD will also have the A620/A620A series continuing its role to serve the entry-level segment. There are plans to offer even more price adjustments, making them a viable option for ODMs and system builders to attract more customers.

Meet The LGA 1718 Socket - How Long Will This One Last?
As mentioned earlier, AM4's reign is finally over and the AM5 socket is here now. The new socket moves from a PGA (Pin-Grid-Array) design to an LGA (Land-Grid-Array) layout. The new LGA 1718 socket offers more pin connections to the CPU, allowing for more communication channels with the board itself and enabling support for enhanced features that the new platform has to offer.
As for longevity, AMD has committed to a 2027+ plan for its latest AM5 socket. The AM4 platform is a testament to AMD's support for its consumers and while the newer 500-series lineup was locked out initially, the company and its partners worked towards extending support for older processors on the newer chipsets and newer CPUs on older motherboards. The AM4 platform continues to be the best seller in the Ryzen lineup, but that would change with the introduction of more budget and feature-rich designs for the AM5 socket like the 800-series.
Cooler Compatibility With AM5 Socket
The AMD Ryzen 7000/8000/9000 Desktop CPUs will feature a perfect square shape (45x45mm) but will house a very chonky integrated heat spreader or IHS. The CPUs will be the same length, width, and height as the existing Ryzen Desktop CPUs and are sealed across the sides so applying thermal paste won't fill the interior of the IHS with TIM. That's also why current coolers will be fully compatible with the latest Ryzen CPUs.
