AMD casts aging CPU and GPU designs to Google’s Chromebooks • The Register

To satisfy Chromebook customers’ most discerning wants, AMD has Frankensteined collectively a line of chips constructed from cast-off CPU and GPU architectures.
AMD’s 7020C-series components — the “C” standing for Chromebook — introduced right this moment sew collectively the chipmaker’s four-year-old Zen-2 cores with an over two-year-old RDNA-2 GPU, and a contemporary reminiscence controller with help for the newest LPDDR5 DRAM and assemble all of it utilizing a TSMC 6nm course of.
For reference, AMD launched its Zen-4 pocket book chips in January, which characteristic RDNA-3 built-in graphics, and are fabbed utilizing a 4nm course of. However aside from bearing the identical Ryzen 7000 title, AMD’s newest Chromebook chips share nearly nothing in widespread with these components.

Regardless of the growing older CPU and GPU, AMD claims the processors can obtain between 17 and 19.5 hours of battery life. That is probably all the way down to the extra fashionable 6nm course of tech used to fab the components. That size of time was estimated from the crXPRT battery life exams, we’re advised.

As you may anticipate these chips aren’t precisely AMD’s speediest.  All 4 Chromebook-centric SKUs introduced Tuesday characteristic a 15W TDP and AMD’s Radeon 610M graphics. And earlier than you get excited in regards to the prospect of built-in RDNA-2 graphics — the identical tech powering Microsoft’s Xbox Collection X|S, Sony’s PlayStation 5, and Valve’s Steam Deck — TechPowerUp places the Radeon 610M’s relative efficiency at someplace between the 14-year-old Nvidia GeForce GT240 and a 15-year-old 9600 GT. That stated, the onboard graphics helps as much as three 4K screens, which is greater than will be stated about Apple’s vastly extra highly effective M2 SoCs.

The most important differentiator between these chips comes all the way down to the CPU. On the backside 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 two.4GHz and a lift clock of three.5GHz. Leaping as much as the Athlon Gold unlocks multi-threading, two further megs of cache, and 200MHz increased enhance clock.
Issues solely begin getting fascinating while you step as much as AMD’s Ryzen 3 7320C and Ryzen 5 7520C, each of which characteristic four-cores and eight threads, and 6MB of cache. Choosing the R5 will web you barely increased base and enhance frequencies at 2.8GHz and 4.3GHz over the two.4GHz base and 4.1GHz enhance on the R3.
AMD’s technique of mashing older core and GPU designs into “fashionable” chips is under no circumstances a brand new phenomenon. For a few years shopping for a desktop CPU with built-in graphics additionally meant dwelling with older course of tech and core designs. The Ryzen 3400G, for instance, launched in 2019; as a substitute of the then-new Zen-2 core and TSMC’s 7nm course of, it featured the older Zen+ structure constructed on GlobalFoundries’ 12nm course of node.

In any case, you’ll be able to anticipate AMD’s 7020C-series components making their method into a spread Chromebooks, together with these made by Dell and Asus, beginning in Q2 2023. ®
