Highly anticipated: AMD’s Financial Analyst Day 2022 has simply taken place, and with it got here a slew of details about its upcoming and future processors, together with Zen 4 and the next-generation RDNA 3 graphics playing cards. In the case of its CPUs, AMD guarantees a whopping 35% efficiency enhance over Zen 3, whereas the GPUs supply a 50% efficiency per watt uplift.
AMD’s desktop CPU roadmap confirms a number of details about Zen 4. Firstly, the corporate’s 3D V-cache expertise used within the Ryzen 7 5800X3D will likely be a part of the brand new processor sequence, although it by no means revealed what number of chips will put it to use and whether or not they’ll launch alongside the brand new processors. As a reminder, the Ryzen 7 5800X3D stacks a 41mm2 die containing solely L3 cache over the Zen 3 core advanced die, growing the quantity of L3 cache from 32MB to 96MB.
When AMD mentioned Zen 4 at Computex final month, it promised a larger than 15% single-thread efficiency uplift over Zen 3. It now says general efficiency enchancment is 35% larger than the present era. Whether that additionally refers to single-threaded efficiency or multi-threaded (or a mixture of each) is unclear.
We know elevated clock speeds, an space the place AMD has lengthy stood within the shadow of Intel, will likely be an enormous a part of Zen 4’s efficiency increase. The processor it confirmed off at Computex, believed to be a prototype of the Ryzen 9 7950X, ran at 5.5 GHz on “most” threads when working a Ghostwire Tokyo demo, and the corporate later confirmed the CPU was not overclocked.
We additionally see Zen 4c (Bergamo) on the roadmap, which will increase the usual most Zen 4 core rely from 96 to 128, and point out of the 4nm course of—an enhanced 5nm node that will likely be used within the cellular Phoenix Point line that mixes Zen 4 cores, RDNA 3 graphics, and Xilinx’s Artificial Intelligence Engine (AIE).
Elsewhere, the roadmaps reveal that the Threadripper household will likely be getting the Zen 4 therapy. There have been fears that AMD was letting the model die off, however we do not know if, like Zen 3, solely the Threadripper Pro sequence will likely be a part of the next-gen chips.
As for Zen 5, codenamed Granite Ridge and sure known as the Ryzen 8000 sequence, will probably be constructed on the 4nm/3nm processes, use the identical AM5 socket as Zen 4, and is ready to reach in 2024.
Jumping to AMD’s graphics playing cards and RDNA 3, the spotlight statistic is that the structure will supply a 50% efficiency per watt uplift over RDNA 2, which sounds engaging however ought to be taken with some salt as it is going to probably be a best-case situation. We can nonetheless count on the flagships to be power-hungry. Whether they’ll rival the rumored RTX 4090/4090 Ti’s 600W to 800W stays to be seen.
Like Zen 4, RDNA 3 will likely be constructed on 5nm course of expertise from TSMC. It boasts “superior multimedia capabilities” similar to AV1 encode/decode assist and comes with DisplayPort 2.0 assist.
Other new options embody a reworked compute unit (CU) and next-generation Infinity Cache. We even have affirmation that RDNA 3 GPUs will return to a chiplet design, one thing that has been rumored for some time. It would be the first time AMD has used the design in shopper playing cards for the reason that Vega period.
AMD additionally confirmed the existence of RDNA 4. It’s primarily based on the 3nm course of and will launch in the identical 12 months as Zen 5: 2024.
The Zen 4 CPUs and RDNA 3 graphics playing cards are set to launch later this 12 months.
