AMD Ryzen 8000 "Granite Ridge" Desktop CPUs Rumored To Utilize Same IO Die As Ryzen 7000

Aug 04, 2023

AMD's Ryzen 8000 "Granite Ridge" Desktop CPUs are rumored to utilize the same IO die as the existing Ryzen 7000 chips.

According to some new information by Olrak29_ & Kepler_L2, it looks like AMD will be keeping one part of its next-gen Ryzen 8000 Desktop CPUs, codenamed Granite Ridge, the same as the existing Ryzen 7000 CPUs.

By the way this is a leak, Granite Ridge uses the same IO Die https://t.co/CrHMHMCPlI

We know from previous information that AMD's Ryzen 8000 family of Desktop CPUs will launch in 2024 on the AM5 socket. The next-generation family was expected to support Zen 5 CPU cores & RDNA 3.5 iGPU cores however, one aspect of the family has changed since AMD revealed the CPU plan in its official slide back in June 2023. The slide clearly mentions 65W to 170W CPUs. It could include both APUs and CPUs but we know for certain that 170W is a power target that Ryzen APUs aren't designed around.

The AMD Ryzen 8000 Desktop CPUs will utilize the next-gen Zen 5 core architecture, offering a big leap in performance and power efficiency but at the same time, one chiplet will be kept the same & that's the IOD (I/O Die). The rumor states that nothing has changed from the Ryzen 7000 for the IO die which means the 28 PCIe Gen 5 lanes, memory controllers, USB functionalities, and even RDNA 2 iGPU cores will remain untouched.

Reusing the same IO die should have no major impact though. The company has previously reused Zen 2's IOD for Zen 3. In fact, the reusability will definitely save AMD some costs and make it easy to produce Ryzen 8000 chips using a good-to-go IOD solution.

Interestingly, AMD lists the Ryzen 7000 "Desktop" CPUs with Navi 3.0 support whereas the Radeon 710M iGPU in fact is based on the RDNA 2 graphics core. The next-gen lineup was mentioned to support the newest RDNA 3.5 GPU core which will be coming to the Strix APU family next year but that isn't the case either.

The AMD Ryzen 8000 CPUs will also retain the 2 compute units which should be enough for any diagnostic operations and office workloads since specific SKUs work great for office and business environments where a dGPU isn't essential. This also means that the IOD might be based on a 6nm process node like before. Some of the key features of Zen 5 CPUs include:

For those who want to see RDNA 3.5 GPU cores on the AM5 platform will have to wait for the AMD APU lineup. The red team has yet to launch its Ryzen 7000G "Phoenix" family for desktops & while motherboard makers were excited to share their plans for the lineup at Computex 2023, they have now gone silent regarding a potential launch. We might see them later on but it looks like AMD has currently focused its production towards the mobility platforms.
