As previously reported, AMD is preparing unusual mobile processors for budget laptops, codenamed Mendocino. They combine TSMC’s advanced 6nm process technology to deliver over 10 hours of battery life for laptops based on them, graphics on the advanced RDNA 2 architecture, and processor cores on the outdated Zen 2 architecture. AMD immediately disclosed the number of cores and four units but did not say anything about the video-core.
Now a slide has appeared on the Web, according to which the integrated AMD Mendocino graphics has only 2 Compute Units, which is equivalent to 128 stream processors. Also, although the memory controller supports LPDDR5 RAM, it only has a couple of 32-bit channels. This is half as usual, which means that the memory bandwidth will also be half as much. But integrated graphics use RAM as video memory. As a result, the performance is only enough to display the image. Of the good, there is support for decoding AV1 and VP9.
The Zen 2 cores also went under the knife. The amount of the L3 cache was cut to 4 MB. Previously, this configuration was only used in mobile Ryzen 4000 and desktop hybrid Ryzen 4000G.
AMD Mendocino will fit into thin laptops and Chromebooks ranging from $400 to $700. The sale is expected towards the end of the year.
