Documentation leak confirms preparation of AMD Ryzen processors for Chromebooks

Documentation leak confirms preparation of AMD Ryzen processors for Chromebooks


One of the users of Twitter was discovered documentation for AMD’s new energy-efficient hybrid processor, the Ryzen 3250C. We talked about this chip as part of a mysterious device called Google Zork recently. It is likely that we are talking about a new model of the Pixelbook Chromebook.

As indicated in the documentation, the chip belongs to the eighth generation of hybrid (APU) x86-compatible AMD processors and is based on the Zen architecture of the first generation (Raven Ridge). It has built-in I / O controllers, a graphics subsystem, as well as memory controllers. Thus, for the chip to function, it does not require an additional chipset on the motherboard, which reduces the total cost of production of the final product.

The novelty uses two physical cores, as well as four virtual threads. The frequency is not indicated, but the earlier appearance of this processor in synthetic tests indicated a base frequency of 2.6 GHz. The declared size of the L3 cache is 4 MB. According to the document, the new model provides the number of operations per cycle (IPC) 40% higher than the previous generation APU.

Technical characteristics of the graphics subsystem are also not indicated. However, it is reported that it supports the DirectX 12 API, OpenGL 4x / 2.1, as well as OpenCL 2.0. It is very likely that first-generation Vega graphics will be applied here.

In addition, the document reports that the APU is presented for different connectors: with support for the Socket AM4 connector, as well as Socket FP5 for compact ultrabooks and devices made in the 2-in-1 form factor. Different levels of TPD are announced for the new processor – from 4.5 to 15 watts.

As Tom’s Hardware resource points out, the new Ryzen 3000C series APUs (previously also reported Ryzen 3700C with Vega Graphics) For the first time, they received support for Data Fabric (SDF) technology, which is part of the Infinity Fabric interconnect, which is used as a bridge between CPU and GPU architectures. According to AMD, this technology maximizes bandwidth to ensure minimum latency and increase overall maximum performance.

The leak of documentation can also be an indirect evidence in favor of the imminent announcement of a device based on the above hybrid processor.
