AMD deploys the artillery in the ‘chromebooks’: its Ryzen 5000 C ‘Zen 3’ chips promise us up to 13 hours of autonomy

The inertia that AMD has acquired since the arrival of the first revision of the Zen architecture has been very favorable, but the one that has managed to stand out in a resounding way has been the Zen 3 microarchitecturewhich arrived on desktop PCs at the end of 2020, and only a few months later it also landed on laptops.

Already then the interesting performance/watt ratio that these microprocessors have invited us to anticipate that they would end up reaching the chromebookand, although they have been slow to do so, the first Zen 3 microarchitecture chips for these teams are already here.

AMD has introduced four new Ryzen 5000 processors belonging to the C series that are capable of simultaneously processing up to 16 threads of execution, incorporate Vega graphics and have a 15 watt TDP. Also, like the other CPUs in this family, they are being manufactured by TSMC using its 7nm FinFET photolithography. Sounds really good.

Up to 16 execution threads and 13 hours of autonomy

The new Ryzen 5000 C processors are not the only chips that AMD has to compete in the segment of the chromebook. In fact, these CPUs are going to coexist with the Ryzen and Athlon 3000C, which implement the Zen microarchitecture and from now on will be relegated to the mid-range. The Ryzen 5000 C will be positioned in the premium segment, so we will find them in the most ambitious teams in this category.

There is no shortage of chips, there is a huge deficit: we are manufacturing more than ever and it is still not enough

As expected, the new chips, according to AMD, give us higher performance (the Ryzen 3000 C processes at most 8 threads of execution simultaneously) and a maximum autonomy of 13 hours. The most ambitious of them all, the Ryzen 7 5825C, works at a maximum clock frequency of 4.5 GHz and incorporates 20 MB of level 2 and 3 cache, specifications that on paper place it on a par with many processors. Ryzen 5000 for mainstream laptops.


In the next slide AMD compares the performance of the new Ryzen 5000 C with that of the Ryzen 3000 C, and, as we can see, the new chips are imposed with an insulting clarity. The largest difference arises in the multithread test scenario, but it is understandable if we consider that the Ryzen 7 5825C simultaneously processes 16 threadsand the Ryzen 7 3700C can only deal with 8 threads at a time.


One of the distinguishing features of the chromebook, beyond its price, if we compare them with conventional laptops is its autonomy. And in this territory, what AMD promises us also looks good. According to this company its Ryzen 5 5625C bend clearly to an Intel Core i5-1135G7 processor, although ideally we should take this wisely until we have a chance to check it out when one of the new chromebook fall into our hands.


The first ‘chromebooks’ with Ryzen 5000 C CPU are about to hit stores

AMD has confirmed that in the coming weeks the first chromebook equipped with the new Ryzen 5000 C processors with Zen 3 microarchitecture. HP Elite C645 G2 will integrate up to a Ryzen 7 5825C chip, and the Acer Spin 514 It will also offer us that same CPU in its most ambitious configuration. Both computers have SSD storage with PCIe 3.0 NVMe interface, Wi-Fi 6 and Bluetooth 5.2.
