The 5nm Zen 4 architecture-based AMD Ryzen 7000 “Raphael” desktop CPUs have been leaked ahead of their unveiling at Computex 2022 tomorrow.
AMD Ryzen 7000 Leak: World’s first 5nm desktop CPUs, dual Zen 4 chipsets, up to 16 cores, RDNA-2 GPU, coming to market this fall
The AMD Ryzen 7000 processors are powered by the brand new Zen 4 core architecture, which will be a complete architectural overhaul. The CPUs retain the chiplet design along with high core counts. AMD hasn’t confirmed anything regarding the specs, but it says they’ll be powered by TSMC’s 5nm processing nodes and were designed for gamers first. The leaked slide from Videocardz confirms that the CPU will use two Zen 4 CCDs (Core Complex Dies) based on TSMC’s 5nm process and a single I/O die (IOD) based on the 6nm Process Node is manufactured by TSMC.
AMD Ryzen ‘Zen 4’ Desktop CPU Expected Features:
- Brand New Zen 4 CPU Cores (IPC / Architectural Enhancements)
- Brand new TSMC 5nm process node with 6nm IOD
- Support on AM5 platform with LGA1718 socket
- Dual channel DDR5 memory support
- 28 PCIe lanes (CPU exclusive)
- 105-120W TDPs (high end ~170W)

The next-gen Zen 4-based Ryzen desktop CPUs will be codenamed Raphael, replacing the Zen 3-based Ryzen 5000 desktop CPUs, codenamed Vermeer. Based on the information we currently have, since these will be the standard Zen 4 powered chips, we expect to see up to 16 cores and 32 threads again on the upcoming Ryzen 7000 desktop CPUs.
The all-new Zen 4 architecture is rumored to deliver a single-threaded performance boost of over 15% over Zen 3, reaching clock speeds of around 5GHz as demonstrated by them at CES 2022. GHz across all cores (core count not mentioned ), meaning the single-threaded clock speed would be over 5GHz. We can expect an all-core boost of up to 5GHz on the next-gen Zen 4-powered platform. The CPUs will also feature RDNA 2 iGPU, which can be used on the latest AM5 motherboards via HDMI 2.1 FRL and DP 1.4 connectors.
The AMD Ryzen 7000 desktop CPUs will be perfectly square in shape (45 x 45mm) but will house a very chunky Integrated Heat Spreader, or IHS. The CPUs are the same length, width, and height as existing Ryzen desktop CPUs and are sealed on the sides so applying thermal paste doesn’t fill the interior of the IHS with TIM. For this reason, current coolers will also be fully compatible with Ryzen 7000 chips.
In terms of TDP requirements, the AMD AM5 CPU platform will feature six different segments, starting with the flagship 170W CPU class, which is recommended for liquid coolers (280mm or higher). It looks like this will be an aggressively clocked chip with higher voltages and CPU overclocking support. This segment is followed by CPUs with 120 W TDP, for which the use of a high-performance air cooler is recommended. Interestingly, the 45-105W variants are listed as SR1/SR2a/SR4 heat segments, meaning they would require standard heatsink solutions when operating in a standard configuration, so not much more is required to keep them cool keep.
In terms of launch, the AMD Ryzen 7000 desktop CPUs are slated to launch this fall, meaning we won’t see the chips in action until September 2022 at the earliest. It’s definitely surprising as the motherboard makers are mostly done with their upcoming X670E, X670, and B650 offerings that will be unveiled tomorrow. AMD is expected to reveal more details about its Ryzen 7000 CPU family at Computex, so tune in to the event here tomorrow!
