HELP Rembrandt after two generations aimed at increasing processor performance (Renoir doubling the number of processor cores; and Cezanne increasing IPC) will focus on graphical performance. After years of using tuned architecture Vega (GCN5) occurs on RDNA 2, an almost two-generation shift. We can only hope that with a stabilized financial situation, AMD will no longer deploy new graphics architectures to the APU for about two generations…
VLIW4 -> GCN1 -> GCN2 -> GCN3 -> GCN4/Polaris -> GCN5 / Vega -> RDNA -> RDNA 2
… But more often. Vega has found application in three generations of APUs, and although Intel does not yet threaten its position in the desktop and has reached half of its performance, in the mobile sphere it already achieves similar performance. Above all, the latest generation of multimedia equipment is missing. The implementation of a substantially innovated graphics core is certainly related to the support of LP (DDR5), which bring a significant shift in the data throughput of the system bus, which gives room to increase graphics performance, which would otherwise be more or less limited by DDR4 memory throughput.
The 6nm manufacturing process will be served by the APU Rembrandt AMD’s premiere, which also means the first deployment of the EUV process in the PC segment. Recall that the EUV version of the 7nm process did not succeed as TSMC as planned, so this process was only partially applied in the mobile world (only the deployment of HiSilicon is known). The TSMC refers to the tightened version of the 7nm EUV production as a 6nm process. Since no PC manufacturer in the world also produces anything on Samsung on 7nm or newer lines, nor does Intel use EUV, it will be Rembrandt in this respect it is the premiere (albeit only formal; from the 6nm process, compared to the 7nm, no fundamental shift in frequencies or consumption takes place; rather silicon is saved).
The new APU will also be the first (and for a long time the only) product from AMD stables with an integrated USB 4.0 controller (or, if you prefer the illogical marketing label “USB4”). Desktop Zen 4 at the end of next year, it will support USB 4.0 in the form of a separate controller, as integrated support will probably not pay off (for low-end boards, it would probably end up unused, so it will be added only where it makes sense).
Processor cores will undergo the smallest change. They will remain for a generation Zen 3 (Although some sources add “+” to them, the meaning of which is still unknown – perhaps a slightly higher IPC?). However, it seems that after several generations of products, Intel will have the upper hand this time. Its upcoming Core generation builds on the Alder Lake architecture, which is the opposite Ice Lake / Rocket Lake increases IPC by 19% and in addition brings a fourth generation 10nm process called Intel 7, which significantly shifts the achievable frequencies in situations limited by TDP. Rembrandt thus, over time, it will be a product focused on graphics rather than processor performance.
The launch of the mobile version is expected at CES in January, but according to current information, AMD started large-scale series production at the turn of August and September at the latest. This is relatively early compared to the usual schedule, but it can be assumed that with the current unceasing demand for hardware, AMD expects high sales and has started production to be able to fill stocks in advance. According to leaker Greymon55, the factory in China, which AMD uses to encapsulate its products, is preparing to process six new products in the first half of 2022.
