AMD has unveiled a line of Ryzen 5000C processors specifically for Chrome OS laptops. The family consists of four chips offering up to eight processing cores and a nominal TDP of 15W. The processors are manufactured using the 7 nm process and are based on the Zen 3 architecture. Each chip also contains up to eight Radeon RX Vega graphics cores.
According to the manufacturer, Chromebooks based on Ryzen 5000C processors offer up to two times longer battery life compared to models based on Intel Tiger Lake processors. At the same time, the company aims to hit the high-end of Chromebooks with the new high-performance Ryzen 5000C, while using the existing Ryzen 3000C chip series in lower-end Chrome OS-based models.
In fact, the Ryzen 5000C processor series is a repurposed series of energy-efficient mobile Ryzen 5000U chips. Ryzen 5000C processors differ from the latest in maximum clock frequencies increased by 100 MHz, but maximum frequencies of graphics cores reduced by 100-200 MHz. The only exception is the Ryzen 3 5125C chip, which is a completely new processor as there are no dual-core and quad-thread models in the Ryzen 5000U series. The characteristics of the chips of the Ryzen 5000C series can be found in the table below.
Obviously, using eight-core processors should boost multithreaded performance significantly, while increasing the number of executable instructions per clock (IPC) that the Zen 3 architecture offers also contributes to a good increase in single-threaded performance should . Using the 7nm-based Radeon RX Vega “on-board” will also benefit from higher performance compared to the 14nm-based Vega integrated graphics of the Ryzen 3000C models.
Compared to the same Ryzen 7 3700C, the new Ryzen 7 5825C offers up to 67% faster single-threaded performance in the Webxprt 3 test, according to AMD itself, while more than twice the multi-threaded performance of the new chip is shown in the Geekbench benchmark 5 claims, although the latter doesn’t quite reflect CPU performance in real-world conditions.
Since most games on Chromebooks run in a browser window, the new chip’s claimed performance gain of up to 85% in the Motion Mark test, which simulates graphics load in a browser, compared to the previous generation chip can be very welcome.
Since Intel hasn’t released Chromebook-optimized Alder Lake processors yet, AMD is comparing its new products to the Tiger Lake lineup. For example, the Ryzen 7 5825C is pitted against the Intel Core i7-1185G7, and AMD’s latest is 7% faster in Webxprt 3, 25% better in Geekbench 5 Multi-Threaded, and 10% stronger in Motion Mark.
However, the most important feature of AMD Ryzen 5000C series processors is their energy efficiency. The manufacturer claims that the Ryzen 5 5525C model in a Chromebook offers up to 94% (almost double) battery life compared to the Intel i5-1135G7 in the CrXPRT2 benchmark, a dedicated test for Chromebook batteries by Principled Technologies .
In terms of security feature support, the new Ryzen 5000C chips copy them from the Ryzen PRO series processors. Among other things, support for Secure Boot, AMD Secure Processor and Google TPM technologies is declared here.
AMD is touting today’s HP Elite C645 G2 and Acer Chromebook Spin 514 as examples of high-end Chromebooks that will use the Ryzen 5000C.
Both innovations are based on the flagship Ryzen 7 5825C with eight cores. Many manufacturers will also be presenting their solutions based on the new Ryzen 5000C processors in the foreseeable future.
