Zen 4: 16 large cores also for laptops

Leaving aside a few exceptions that did not follow the concept defined by AMD, until now laptops were the domain of the APU, a solution combining processor and graphics cores, often in one piece of silicon. With a generation Zen 4 the situation is likely to be different. It does not change the fact that AMD will present the APU in CES 2022 in less than three months Rembrandt with eight cores Zen 3+ and RDNA 2 graphics. It doesn’t change that AMD will probably come up with the APU a year later Phoenixwhich kernels Zen 3+ replaces kernels Zen 4, again eight.

However, it is changing that these products will not be the only AMD processors for the mobile segment, but during their era the offer will be expanded by a mobile version of the processor Raphael (We are waiting for its desktop version next autumn, it will be intended for socket AM5). While de facto overclocked APUs now serve notebooks in the 65W + segment, APUs will now remain in the lower TDP segment, while the more powerful segment will also offer processors with more than eight cores. That ‘s up to sixteen.

From Raphael the optional presence of RDNA 2 graphics is expected in the long run, but will be slower than the APU version. Which makes sense with regard to the segments that such solutions will serve – the most powerful gaming laptops with separate graphics and mobile workstations. The integrated GPU does not need high 3D performance; its purpose is primarily to display and reduce consumption in a situation where there is no need to perform separate graphics, which the system can then shut down in appropriate situations (internet, documents, video, etc.).

While Intel thanks Alder Lake will be the first manufacturer to offer a reference configuration with sixteen processor cores in the mobile segment, AMD se Zen 4 / Raphael will be the first with sixteen large cores. Alder Lake, as well as his successor Raptor Lake, is based on a maximum of eight large cores; the others are made up of smaller Atom nuclei.
