Biostar B650M Motherboard Review – All The Basic AM5 Features In A Sub-$100 Design

AMD's B650 motherboards have come a long way. From the days their prices were above $150 US to now when you can find a large majority of options close to $100 US. These are decent options for AM5 PC builders and now, we are looking at designs that retail for under the $100 US segment.

Biostar is one of the manufacturers that has a very diverse portfolio of AMD AM5 motherboards, mainly the B650 options. The company focuses on the budget segment with its product stack and recently introduced the B650MT which is an entry-level design that offers all the basic features one can expect from the AM5 platform.

For today's review, we will be testing out the Biostar B650MT motherboard to see if its low price is worth given its performance and onboard features.

The AMD AM5 Platform

But before we talk about the motherboard, let's take a small recap of the AM5 platform itself. 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 & 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.

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 28 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 B650 Series Platform

The B650E & B650 chipsets are designed as a mainstream motherboard solution with the Extreme series featuring both PCIe Gen 5.0 & M.2 while the non-E boards will adopt only PCIe 5 slot designs. The B650 motherboards are the successor to the B550 motherboards and come in at a slightly higher price range. Compared to the X670/E offerings, the B650 chipset comes in a single PCH design. The motherboards carry support for RDNA 2 iGPU too which are 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.

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 now committed to a 2027+ longevity for its AM5 platform and respective motherboards which is great news for builders who have invested in the new Ryzen platform. The motherboards support the upcoming Ryzen 9000 Desktop CPUs based on the Zen 5 architecture & will also feature support for newer generations, whether those be classic or X3D "3D V-Cache" CPU variants.

Cooler Compatibility With AM5 Socket

The AMD Ryzen 7000 Desktop CPUs feature a perfect square shape (45x45mm) but house a very chonky integrated heat spreader or IHS. The CPUs are 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 Ryzen 7000 chips.
