Microsoft today unveiled a host of new mobile devices, and among them were several very interesting.
In particular, the Surface Pro X received a modified Snapdragon SoC 8cx, but there are no details of what it changed.
the Notebook Surface Laptop 3 also received an unusual heart — AMD Ryzen Surface Edition. Microsoft also noted that it was "custom" solution, that is, it differs from that used in other APU AMD. And now we know what exactly the difference is.
AMD issued a press release which has details on these processors, which the company calls the most productive mobile Ryzen in history. In addition, these processors are already available on the AMD website in the relevant section.
the New APU only two: Ryzen 7 3780U Microsoft Surface Edition Processor and Ryzen 5 3580U Microsoft Surface Edition Processor. For convenience, we will call them Ryzen Ryzen 3780U 7 and 5 3580U. This hybrid processors of the mobile line Ryzen 3000, and this means that they are based on the architecture of Zen+ and are produced according to 12-nanometer process technology. Really, the APU, though unique, but slightly different from the usual. In particular, Ryzen 7 3780U is an analogue of Ryzen 7 3750H with some differences, and Ryzen 5 3580U very similar to Ryzen 5 3550H. In fact, the only difference in TDP and the GPU.
so, Ryzen Ryzen 3580U 5 and 7 3780U got four cores with SMT support. The first operates at frequencies of 2.1-3.7 GHz, the second — and 2.3-4.0 GHz. TDP here the custom, but the base value is equal to 15 watts versus 35 watts for a conventional counterparts.
as for GPU, the Junior model is Vega 9 576 stream processors, and high — Vega 11 with 704 processors. In both cases it is on one compute unit (64 stream processors) more than 7 3750H Ryzen Ryzen 5 and 3550H.
If we are talking about mobile APU AMD, then Ryzen 7 3780U has the highest performing GPU, although exactly the same there are table models: 3400G 5 Ryzen, Ryzen Ryzen 2400G 5 and 5 2400GE.
Thus, there is nothing unique to the new CPU, however this is my first experience with AMD, so later we can see a more specific processors created for the needs of a partner company.
