AMD ‘Renoir’ Ryzen 4000 Series APUs For Desktop Confirmed In Leaked B500 AM4 Socket Motherboard Roadmap

AMD’s ‘Renoir’ Ryzen 4000 Series processors, which were earlier meant primarily for laptops, are headed to desktop computing as well, confirmed a leaked roadmap for new motherboards. The ZEN 2 based mobility CPUs would be accommodated on the highly compatible AMD AM4 socket. The AMD Ryzen Renoir APUs should offer exceptionally quiet but powerful performance.

New motherboards with the B550 chipset for AMD’s new processors will also accept the 7nm AMD Renoir Ryzen 4000 Series ZEN 2-based APUs. The new motherboards are capable of supporting PCIe 4.0, however, the mobility APUs adapted for desktop use is limited to PCIe 3.0. The rest of the specifications and features would work as per the new chipset for the highly mature AM4 socket.

AMD Renoir Ryzen 4000 Series ZEN 2-Based APUs Coming To Desktops:

Renoir is the codename for ZEN 2 based APUs from AMD. This essentially means they are based on the ZEN 2 Architecture and come with an onboard or Integrated Graphics Processor (iGPU). A mystery AMD Renoir APU with 8 Cores and 16 Threads appeared online recently. Hence it was only a matter of time before motherboard manufacturers indirectly confirmed the existence of the powerful but lightweight APU for desktop use.

AMD ‘Renoir’ Ryzen 4000 Series CPUs, based on the ZEN 2 Architecture and manufactured on the 7nm Fabrication Node, are headed to the desktops as well, confirmed two motherboard manufacturers. There have been several hints about the AMD Renoir CPUs being tested for desktop applications. A mystery 8 Core AMD CPU was recently spotted in a leaked entry over at UserBenchmark, and the Ashes of the Singularity (AotS) benchmark even confirmed the name of expected upcoming Renoir desktop APU. The AMD ‘Renoir’ Ryzen 7 4700G has a 65W TDP.

Gigabyte and ASRock Confirm Future Availability Of AM4 AMD Renoir Ryzen 4000 Series APUs For Desktop Motherboards:

The first leak comes from Gigabyte. Their presentation for the newly introduced B550 chipset motherboards contained a future roadmap for AMD 500-series chipset motherboard. The slide confirms that AMD will launch Ryzen 4000G Renoir APUs. Needless to add, this is a direct confirmation of the codename as well as the series moniker for desktop use.

Gigabyte also mentions X570, B550, and (yet unreleased) A520 chipset will be compatible with Renoir APUs. The presentation went on to add ‘Future CPUs’ named Vermeer. So far, no manufacturer, including AMD, has confirmed the existence of any such CPUs or APUs. But Gigabyte went ahead and confirmed the codename of the Ryzen 4000 series processors. The Vermeer APUs would succeed the current-generation Matisse APUs meant for desktops. Incidentally, the AMD Matisse Ryzen 3000 CPUs will succeed the Picasso Ryzen 3000G CPUs and support PCIe 4.0.

Another popular motherboard manufacturer, ASRock, reconfirmed the future availability of AMD Renoir Ryzen 4000 desktop APUs and added that these processors with integrated GPUs will be limited to PCI-Express Gen 3 or PCIe 3.0. Incidentally, the new B550 motherboards with AM4 sockets do feature PCIe 4.0 support. However, the ZEN 2 based AMD Renoir Ryzen 4000 Series processors are limited to PCIe 3.0. Hence a compromise in the speed and bandwidth is expected.

The B550 Taichi website added to the confirmation by mentioning compatible memory configurations available for the AMD Renoir APUs. There appears to be no difference in terms of memory support for Matisse and Renoir. In other words, the Renoir and Matisse processors would offer easy upgradability.
