AMD Ryzen 7000 ‘Raphael’ desktop CPUs based on the 5nm Zen 4 architecture have been leaked ahead of their unveiling tomorrow at Computex 2022.
AMD Ryzen 7000 Leaks: World’s First 5nm Desktop CPU, Dual Zen 4 Chips, Up to 16 Cores, RDNA 2 GPU, Launching This Fall
AMD Ryzen 7000 processors will be powered by the new Zen 4 core architecture, which will be an overhaul of the architecture. CPUs will retain the chiplet design along with the high core count. AMD has not confirmed anything regarding the specifications but it is said that it will be powered by a 5nm TSMC process node and designed for gamers first. The leaked chip from Videocardz confirms that the CPU will use two Zen 4 CCDs (Core Complex Dies) based on TSMC 5nm process and an I/O die (IOD) that is manufactured on a TSMC 6nm process node.
Expected Features of AMD Ryzen ‘Zen 4’ Desktop CPU:
- All-new Zen 4 CPU cores (IPC/architectural improvements)
- Brand new TSMC 5nm process knot with 6nm IOD
- Support on AM5 platform with LGA1718 . socket
- Dual channel DDR5 memory support
- 28 PCIe slots (CPU specific)
- 105-120W TDPs (upper range ~170W)
The next-generation Zen 4-based Ryzen desktop CPUs will be codenamed Raphael and will replace the Zen 3-based Ryzen 5000 desktop CPUs codenamed, Vermeer. From the information we currently have, since these will be the standard chips powered by Zen 4, we expect to see up to 16 cores and 32 threads again on the upcoming Ryzen 7000 Desktop CPUs.
The new Zen 4 architecture is rumored to provide more than 15% more single-thread performance over Zen 3 and reach clock speeds of around 5GHz as shown at CES 2022. The demo showed the undisclosed Zen 4 Ryzen 7000 CPU which It operates at 5GHz across all cores (core number not mentioned) which means that the single-thread clock speed will exceed 5GHz. We can expect a boost of up to 5GHz for all cores on the next generation Zen 4 powered platform. The CPUs will also be equipped with an RDNA 2 iGPU which can be used through the HDMI 2.1 FRL and DP 1.4 connectors on the latest AM5 motherboards.
AMD Ryzen 7000 desktop CPUs will feature a perfectly square shape (45 x 45 mm) but will have an integrated highly interlaced heat splitter, or IHS. The CPUs will be the same length, width, and height as current Ryzen Desktop CPUs and are sealed across the sides, so applying thermal paste won’t fill the interior of IHS with TIM. This is also why existing coolers will be fully compatible with Ryzen 7000 chips.
For TDP requirements, the AMD AM5 CPU platform will feature six different sections starting with the 170W main CPU class that is recommended for liquid coolers (280mm or higher). It looks like this will be a higher voltage chip with CPU overclocking support. This segment is followed by 120W TDP CPUs which is recommended for high performance air cooler. Interestingly, the 45-105W variants are listed as SR1/SR2a/SR4 thermal chips which means they will require standard heatsink solutions when running in a stock configuration so not much else is needed to keep them cool.
As for the launch, AMD Ryzen 7000 Desktop CPUs are said to launch this fall, which means the earliest we’ll see the chips in action is September 2022. It’s certainly surprising because motherboard makers are mostly ready with the upcoming X670E and X670. B650 Deals To Be Revealed Tomorrow. AMD is expected to reveal more details regarding its Ryzen 7000 CPU family at Computex, so be sure to tune in to the action here tomorrow!
