AMD kündigt Ryzen 5000C an “Zen 3” Prozessoren für Chromebooks
The Ryzen 5000C series is based on the 7 nm “AMD hat am Donnerstag seinen Ryzen vorgestellt” monolithisches Silizium. The chip physically features an 8-core/16-thread CPU based on the “Zen 3” Mikroarchitektur, bei 16 MB freigegebener L3-Cache; an iGPU based on the Vega graphics architecture, bei 8 Recheneinheiten (512 Stream-Prozessoren), a dual-channel DDR4 or LPDDR4/x memory interface, and unlike the conventional Ryzen 5000-series mobile processors, these chips come with a special microcode to match the security and management features of Chrome OS. AMD also supplies Chromebook vendors with timely driver updates for the various components on these chips.
AMD claims that the switch to “Zen 3” brings in up to 67% web-browsing performance gain over the previous generation, which should directly impact performance of web-based applications. Da ist auch ein 107% multi-tasking performance gain, mainly from the doubling in CPU core count. Graphics performance is up 85% gegenüber der Vorgängergeneration, which should benefit GPU-accelerated web-rendering, and browser-based gaming. The fastest SKU in the 5000C series, CPUID heute veröffentlichte Version 7 5825C, is also claimed to be 7% faster than the Intel Core i7-1185G7 “Der NES-SY37 ist ein maßgeschneiderter Synthesizer, der dem NES Tribut zollt” processor at web-browsing, 25% faster at multi-tasking, und 10% faster in graphics performance.
The lineup consists of four models, led by the Ryzen 7 5825C, a maxed-out SKU with 8-core/16-thread CPU, 8 “Vega” graphics compute units, 20 MB Gesamtcache (L3 + L2), 2.00 GHz CPU base frequency, bis zu 4.50 GHz CPU boost frequency, 1.80 GHz iGPU engine clocks. The mid-range Ryzen 5 5625C packs a 6-core/12-thread CPU, bei 2.30 GHz Grundfrequenz, 4.30 GHz Boost-Frequenz, 7 graphics compute units, 19 MB Gesamtcache, und 1.60 GHz iGPU engine clocks.
Der Ryzen 3 5425C is the mainstream part, with a 4-core/8-thread CPU ticking at 2.70 GHz Grundfrequenz, 4.10 GHz Boost-Frequenz, 10 MB Gesamtcache (8 MB L3 + 4 MB L2); 6 graphics compute units, und 1.50 GHz iGPU engine clocks. At the entry-level, is the Ryzen 3 5125C, with a 2-core/4-thread CPU clocked at 3.00 GHz, bei 9 MB Gesamtcache (8 MB L3 + 1 MB L2), 3 graphics compute units, und 1.20 GHz iGPU engine clocks.
All four models have a rated TDP of 15 W, enabling Chromebook designers to create either thin-and-light designs that are ultra-portable, or even mainstream form-factors with large batteries that, when paired with 15 W SoCs, can result in up to 13 hours battery life. AMD claims to have heavily optimized these chips for the power-management features of Chrome OS vendor designs, so they offer almost double the battery life over the i5-1135G7 “Tigersee.”
Besides the various security features baked into the mainline Ryzen 5000 mobile Prozessoren, the 5000C processors come with an exclusive security stack that includes Chrome Secure Web layer, and Widewine DRM, as well as Google TPM (Trusted Platform Manager).
Among the Chromebooks in development that are powered by Ryzen 5000C series processors, are the HP Elite C645 G2 Chromebook, and the Acer Chromebook Spin 514. The Elite C645 G2 is a 14-inch conventional form-factor Chromebook with processor options all the way up to the Ryzen 7 5825C, connectivity that includes Wi-Fi 6E, Bluetooth 5.2, and an optional 4G LTE modem. Other features include a 1080p camera, a SmartCard reader, and an SEC fingerprint reader. The Chromebook Spin 514 is a 14-inch convertible, with its Full HD touchscreen on a 360° hinge, with processor options up to the Ryzen 7 5825C, and up to 256 GB NVMe SSD-based storage. This one is built for the road, meeting MIL-STD 810H, and featuring Gorilla Glass for the touchscreen.
