AMD is adding 6 nm, RDNA2 and DDR5 for laptops

The Ryzen Mobile 6000 will use an RDNA2 graphics unit and (LP) DDR5 memory for the first time, TSMC’s N6 process is also new. A roadmap from AMD – albeit a bit outdated – shows the manufacturer’s plans for notebooks: In 2022 the change from (LP) DDR4 to (LP) DDR5 memory will take place and the Vega graphics architecture that has been used for years will be replaced by a Navi-2x -Design exchanged with current RDNA2 technology.

AMD is currently selling the Ryzen Mobile 5000H (45W) and the Ryzen Mobile 5000U (15W) alias Cezanne with Zen 3 cores, including those with Lucienne as a refresh of the Ryzen Mobile 4000U ( Renoir ) with Zen 2 cores.

In the future, Rembrandt is to follow Cezanne: Basically, it will remain with Zen 3, but in an improved form than Zen3 +, and in addition, Navi / RDNA2 graphics instead of Vega plus (LP) DDR5 instead of (LP) DDR4 and PCIe Gen4 instead of Gen3. In addition, AMD uses the N6 manufacturing process with extreme ultraviolet exposure ( EUV ), so far the N7 has been used with classic immersion lithography (DUV). TSMC speaks of an 18 percent smaller chip area if N6 is used instead of N7.

Refreshs for cheaper devices

Below Rembrandt U there is still Barcelo U with Zen 3 and Vega including (LP) DDR4, ultimately a continuation of Cezanne with 15 watts. AMD proceeds in the same way as from Renoir to Lucienne: The design remains the same in principle but may receive various improvements. With Lucienne, for example, CPPC2 have been integrated for fast clocking up and a deep sleep mode at low load.

Van Gogh can be found on the roadmap before Rembrandt, but this APU is said to have been deleted. Instead, Dragon Crest appears, a design with 9 watts designed for tablets. It is still based on 7 nm and Zen but should have a Navi / RDNA2 graphics and an LPDDR5 controller.

Pollock remains up-to-date in the affordable range for Chromebooks, among other things. This is a low-power version of Dali like the Athlon Silver 3050e with 6 watts. There is Zen plus Vega in 14 nm, old technology for little money.
