AMD has declared that it'll launch the first of its Ryzen 7000 series CPUs and their new AM5 series motherboard platforms during a live-streamed event at 4:30am IST on August 30. The event was going to be presented by AMD CEO Dr. Lisa Su, CTO and EVP Mark Papermaster and alternative company executives. Fans around the world would be able to tune up on AMD's YouTube channel and catch a replay shortly once the live stream ends. The chip manufacturer would finally reveal the pricing and product specifications and reveal more details of the Zen 4 design on which these new CPUs were primarily based.

AMD has so far confirmed a minimum of one model with up to 16 cores
Motherboards would be based on the B650 chipset that only supports PCIe 5.0

Ryzen 7000 series CPUs, codenamed 'Raphael', were based on the new Zen 4 design. AMD has so far confirmed a minimum of one model with up to 16 cores, manufactured by TSMC on a new 5nm method and organized in standard 'chiplets' that permit for scalable designs and cost-effective integration. Boost clock speeds need to be “significantly above 5GHz.”

Ryzen 7000 series CPUs would use a new LGA (Land Grid Array) CPU package with pads rather than pins, requiring the motherboard socket to have pins that would create contact with them. Also, AMD has mentioned that l of these CPUs would be for the first time feature integrated graphics capabilities, based on the RDNA2 design. Other changes include a doubling of L2 caches and new instructions for accelerating AI workloads. AMD guarantees a 15 percent rise in single-threaded performance compared to the previous generation, plus significantly power efficiency gains.

The new socket and AM5 platforms break upgrade compatibility with AM4 motherboards that have been in use since the original Ryzen desktop CPU launch in 2017. This was necessary in order to introduce support for DDR5 RAM and shift to the PCIe 5.0 interconnect standard. However, the cooler mount and clearance would remain the same, would ensure compatibility with all existing air and liquid coolers.

There would be at least three tiers of desktop motherboards at launch time. Those were based on the X670 Extreme chipset would be aimed towards “the most demanding enthusiasts” who would desire to use multiple PCIe 5.0 devices plus overclocking capabilities thanks to high-end power delivery features. The X670 chipset was for to “the bulk of enthusiasts and gamers” and would permit PCIe 5.0 lanes for at least one graphics card plus one M.2 memory device. Motherboards would be based on the B650 chipset which would only support PCIe 5.0 for storage devices, which would be able to be fine for most mainstream users.
