AMD scours parts bin for old CPUs, GPUs to put in Chromebooks
The biggest differentiator between these chips comes down to the CPU. At the bottom of the stack is AMD's Athlon Silver 7120C, a two-core, two-hardware-thread chip with 3MB of cache, and a base clock of 2.4GHz and a boost clock of 3.5GHz. Jumping up to the Athlon Gold unlocks multi-threading, two extra megs of cache, and 200MHz higher boost clock.
Things only start getting interesting when you step up to AMD's Ryzen 3 7320C and Ryzen 5 7520C, both of which feature four-cores and eight threads, and 6MB of cache. Opting for the R5 will net you slightly higher base and boost frequencies at 2.8GHz and 4.3GHz over the 2.4GHz base and 4.1GHz boost on the R3.
AMD's strategy of mashing older core and GPU designs into"modern" chips is by no means a new phenomenon. For many years buying a desktop CPU with integrated graphics also meant living with older process tech and core designs. The, for example, launched in 2019; instead of the then-new Zen-2 core and TSMC's 7nm process, it featured the older Zen+ architecture built on GlobalFoundries' 12nm process node.
In any case, you can expect AMD's 7020C-series parts making their way into a variety Chromebooks, including those made by Dell and Asus, starting in Q2 2023. ®

Hypoxia extends lifespan and neurological function in a mouse model of agingAging is one of the strong risk factors for the most common diseases on our planet, but we have few interventions that delay aging (including dietary restriction). This study reveals that a different type of restriction - oxygen restriction - can extend lifespan and counter neurological demise in a mouse model of accelerated aging.

'Lost' immune cells partly to blame for reduced vaccine response in older peopleUnderstanding the ways our immune response changes as we age holds the key to designing better vaccines and boosting protection for people most at risk. Research published by Dr. Michelle Linterman and her group today in Nature Immunology has explained that the organization of the germinal center, which is vital to the generation of longer-lived protection following vaccination, is altered in aging.
