AMD’S Ryzen 7000 and RDNA 3 chips are set to stun later this year

RDNA 4 also makes an official appearance on the road map.

AMD’S Financial Analyst Day is when it reveals a peek at its upcoming lineup for all the people who really matter in the world of consumer electronic­s: insanely rich investors. But fortunatel­y we lowly consumers get to see the same info, which included details on upcoming plans for the Zen CPU line and RDNA3 graphics processors.

On the desktop side of things, we got more details on Zen 4 AKA Ryzen 7000 ( fave. co/3zndbyr), which is already known to be coming later this year and will provide a single-thread performanc­e boost of 15 percent over Zen 3. The new series of 5nm and 4nm chips will also feature higher clock speeds (which we’ve already seen hinted at in an earlier demo of a Ryzen 7000 chip hitting 5.5 GHZ), plus boost instructio­ns per clock by 8 to 10 percent and memory bandwidth per core by “up to 125 percent” for data center use. Efficiency gets a notable improvemen­t,

too: The company claimed Zen 4 CPUS will increase performanc­e per watt by approximat­ely 25 percent, with an overall performanc­e improvemen­t of 35 percent. That’s with a 16-core, 32-thread Zen 4 CPU (the next-gen equivalent of the current Ryzen 9 5950X; fave.co/3catzfh) running a Cinebench multicore test.

Beyond Zen 4 is (wait for it) Zen 5, pushing the manufactur­ing into 4nm and 3nm territory on the AM5 socket. AMD says these chips will arrive in 2024, “built from the ground up to deliver performanc­e and efficiency leadership.” More technical informatio­n on these

Granite Ridge CPUS was not provided. Both Zen 4 and Zen 5 chips will feature standard and 3D V-cache equipped products, as well as a high-density C variant meant for servers.

On the GPU side of things, AMD says its nextgen RDNA 3 architectu­re (Radeon RX 7000 series, on the retail boxes) will be combined with 5nm and 6nm fabricatio­n, advanced chiplet architectu­re, and further enhancemen­ts of the Infinity Cache system ( fave.co/3arujwc). This will deliver “50 percent greater performanc­e-per-watt compared to the prior generation” when they begin to land later this year, but more raw performanc­e comparison­s were not presented. RDNA 4/Navi 4X GPU news was

even more scant; AMD isn’t saying yet what process node will be used for its 2024 GPUS.

AMD also hyped its next-gen laptop SOC designs, code-named Phoenix Point. These laptop boards will combine Zen 4 processors and RDNA 3 mobile GPUS, integratin­g a new image scale processors, more advanced refresh and response display capabiliti­es, and “extreme power management.” Considerin­g the impressive results of the Ryzen 6000 series notebooks ( fave.co3zihnsv), this is promising news indeed…even if it, too, is light on technical detail. Strix Point is the name for laptop

Socs planned for 2024.

Elsewhere in the presentati­on ( fave. co/39dzwzj), AMD spoke about its AI software advancemen­ts, cloud computing hardware, and data center innovation­s. But for consumers, the action will truly begin at the end of 2022 and beginning of 2023. Naturally, the competitio­n isn’t sitting around: That’s when Nvidia’s RTX 4000 series GPUS are expected, and Intel is boosting both its bread-and-butter processor tech and its incipient entry into the red-hot GPU market.
