Final yr, AMD unveiled their entry-level ‘Mendicino’ mobile parts to the market, which mix their 2019 Zen 2 cores and their RDNA 2.0 built-in graphics to create an reasonably priced collection of configurations for mainstream cell units. Though a lot of the dialogue over the previous few months has been about their Ryzen 7040 cell components, AMD has launched 4 new SKUs explicitly designed for the Chromebook area, the Ryzen and Athlon 7020C collection.
Among the most notable options of AMD’s Ryzen/Athlon 7020C collection processors for Chromebooks embody three completely different configurations of cores and threads, starting from entry-level 2C/2T as much as 4C/8T, all with AMD’s RDNA 2-based Radeon 610M cell built-in graphics. Designed for all kinds of duties and customers, together with and never restricted to customers, schooling, and companies, AMD’s Ryzen 7020C collection seems to supply comparable specs and options to their common 7020 collection cell components however expands issues to the broader Chromebook and ChromeOS ecosystem too.
Shortly recapping final yr’s AMD Mendocino cell components, AMD launched 4 SKUs with Zen 2 cores and RDNA 2 built-in graphics. Very like the AMD Mendocino collection for Chromebooks that AMD has introduced, their generic Ryzen/Athlon 7020 components for cell units vary from two entry-level 2C/2T and 2C/4T components as much as two beefier 4C/8T components, all with AMD’s Radeon 610M ‘Mendocino’ built-in graphics.
The highest tier Ryzen 7020 collection CPU, the Ryzen 5 7520U, has 4C/8T, with a base frequency of two.8 GHz and a 1T enhance frequency of as much as 4.3 GHz. Related in specification however barely slower, the Ryzen 3 7320U has the identical 4C/8T however with a 2.4 GHz base and 4.1 GHz 1T enhance core clock velocity, whereas each share the identical 4 MB of L3 cache.
The opposite two chips, Althon Gold 7220U and Athlon Silver 7120U had been once more comparable, however the Athlon Gold 7220U has Simultaneous Multithreaded (SMT) enabled, giving it 2C/4T as an alternative of 2C/2T. All of AMD’s Ryzen/Athlon 7020 collection processors even have a TDP of 15 W, making them extra appropriate for much less intensive workloads and lower-powered options the place issues like extending battery life on the go are extra necessary than uncooked compute energy.
AMD Ryzen/Athlon 7020C Sequence: Mendocino For Chromebooks
Curiously, the Ryzen/Athlon 7020C collection can be primarily based on AMD’s Mendocino graphics and TSMC’s 6 nm node, and the specs between the 7020C and 7020 collection are just about an identical. The one actual distinction between each units of Mendocino chips is that the 7020C SKUs are designed particularly for ChromeOS. On the identical time, the common 7020 collection caters to Microsoft Home windows-based cell units corresponding to notebooks.
|AMD Ryzen 7020 C-Sequence Lineup|

|Athlon Silver 7120C||2C / 2T||2.4 GHz||3.5 GHz||1MB L2 + 2MB L3||Radeon 610M||15 W|
Beginning on the high of the stack, the AMD Ryzen 5 7520C is a 4C/8T half with a 2.8 GHz base and a 4.3 GHz 1T enhance clock frequency. The Ryzen 3 7320C is similar to the Ryzen 5 7520C, nevertheless it’s barely slower, with a base core frequency of two.4 GHz (400 MHz much less) and a 1T enhance frequency of 4.1 GHz (200 MHz much less). Every core has a devoted 512 KB of L1 cache, so the 4C/8T components have a complete L2 cache of two MB and a shared 4 MB pool of L3 cache.
Shifting down the stack, we’ve the Athlon Gold 7220C, a 2C/4T half with a mixed whole of 1 MB of L2 cache, and this particular SKU has the identical 4 MB pool of L3 cache out there to it. It has a 2.4 GHz base frequency, with a 1T enhance frequency of as much as 3.7 GHz. Final however not least, the entry-level Athlon Silver 7120C would not profit from SMT, so it is basically a 2C/2T chip with the identical base frequency of two.4 GHz because the Athlon Gold variant however with a barely slower 1T enhance frequency of three.5 GHz (200 MHz much less).
Whereas TDP is an enigmatic time period, it is all the time a great indication of the place energy will seemingly sit from a producer’s standpoint. All 4 of AMD’s Ryzen/Athlon 7020C collection processors for ChromeOS use their RDNA 2.0-based Radeon 610M built-in graphics, which has 2 x CUs with a complete of 128 shader cores which can be clocked to 1.9 GHz. Though the Radeon 610M is not primarily designed for gaming because of the low variety of shader cores. For reference, the Ryzen 7020/7020C collection options the identical built-in graphics discovered on the higher-end Zen 4 primarily based Ryzen 9 7945HX 16C/32T cell processor, which requires discrete graphics to unleash the extra bandwidth advantages from PCIe 5.0 and PCIe 4.0 graphics chips.
Within the case of the 7020C collection, all 4 SKUs have a TDP of 15 W set by AMD, which suggests these chips are centered on delivering extra effectivity, which is crucial in issues corresponding to extending battery life, which is significant in a cell system.
Regardless of each units of the Mendocino-based Ryzen and Athlon 7020/C collection processors that includes the precise specs, there’s one key and significant distinction. This comes by way of Security measures, and because it’s to be anticipated, a tool designed for Microsoft’s Home windows working system has completely different necessities and wishes from one thing corresponding to ChromeOS. We reached out to AMD to search out out what variations there are in built-in safety, with AMD stating the next:
“These (7020C collection) are the ChromeOS variations of the Mendocino processors launched for Home windows final yr. They do share the identical specs. Nonetheless, the 7020C Sequence is optimized for ChromeOS, together with completely different fusing particularly for ChromeOS safety features. Therefore the 7020U collection can’t be used for Chromebooks”.
Different options of AMD’s Mendocino-based 7020C collection processors embody assist for as much as three exterior 4K60 shows, with the aptitude to assist Wi-Fi 6 and Bluetooth 5.2 units; that is one thing the Chromebook distributors will implement by controllers. Just like the Ryzen/Athlon 7020 collection, the 7020C collection additionally helps the lower-powered LPDDR5 reminiscence, which regarding JEDEC, is LPDDR5-5500 in twin channel mode for the Mendocino-based chips. We requested for additional clarification from AMD on what this fusing of safety features entails, however AMD declined to remark or share further particulars.
As is typical with a brand new launch, AMD did present some in-house efficiency figures, however we normally take these with a pinch of salt with out emphasizing them an excessive amount of. Inside AMD’s slide deck, the AMD to AMD efficiency comparisons had been evaluating the Ryzen 3 7320C in opposition to the Ryzen 3 3250C, which is, in reality, two generations outdated; the earlier technology designed for Chromebooks was the 5025C collection. AMD additionally in contrast efficiency in opposition to Arm-based MediaTek Kompanio chips and an Intel Core i3-N305 processor.
Relating to the broader claims made, AMD claims a 1.8x uplift in efficiency on common in contrast with Arm’s IP, with as much as 15% ‘higher’ efficiency on common in opposition to the competitors on the x86 CISC. AMD additionally claims management in battery life. Nonetheless, as it’s broadly right down to pocket book and Chromebook distributors to optimize by its batteries and power-saving mechanisms, it is a a lot tougher metric to evaluate from a platform standpoint.
Along with their announcement of the Ryzen and Athon 7020C collection for Chromebooks, AMD has additionally introduced two new Chromebooks with its companions primarily based on the 7020C collection. One among these is the Dell Lattitude 3445 Chromebook, which is powered by the AMD 7020C collection processors, with assist for as much as 256 GB of SSD, 16 GB (2 x 8 GB) of LPDDR5 reminiscence, and with built-in assist for Wi-Fi 6 and BT 5.2 units.
The second Chromebook to be introduced is the ASUS Chromebook CM34 Flip (CM3401), which has a 14″ 16:10 facet ratio touchscreen show with an non-obligatory one-touch fingerprint sensor and is powered by as much as and together with the Ryzen 5 7520C processor. The ASUS CM34 Flip additionally has an built-in FHD webcam with a privateness shutter and helps Wi-Fi 6 wi-fi connectivity and BT 5.2 units.
Each the Dell Lattitude 3445 and ASUS CM34 Flip (CM3401) are anticipated to launch someday in Q2 2023, with different units from AMD’s companions anticipated to launch new Chromebooks with Ryzen/Athlon 7020C collection processors across the identical time.
On the time of writing, neither AMD nor their Chromebook companions have offered any indications on costs or different mannequin specs or configurations.
