The possible connection between Google’s upcoming Tensor G5 chip and Imagination Technologies as a GPU vendor is not exactly new. Various reports<\/a> and rumors have already hinted at that, but now we have yet another interesting industry source on the matter. Keep up with us here for a second since the explanation is a bit complicated.<\/p>\n Last month, there was a RISC-V Day Tokyo conference in Japan. One of the materials that came out from the conference was a blog post by postgraduate student Yang Yanling detailing RISC-V and Imagination GPU integration. Imagination Technologies themselves shared the blog post on WeChat, giving it quite a bit of credibility. Said post also featured a breakdown of different chips that use and will be using Imagination GPUs. One of the now-removed tables explicitly mentions the Google Tensor G5.<\/p>\n
As previous rumors have suggested, the Tensor G5, expected to power the Google Pixel 10, will be using the DXT-48-1536 GPU. It is a modern GPU solution that, unlike the Arm Mali-G715 inside the Tensor G3 and G4, is capable of modern feats like ray tracing.<\/p>\n We also know that the Tensor G5 will be fabbed by TSMC<\/a> instead of Samsung on a 3nm-class node. Google will use Arm Cortex CPU cores and a new fully custom image signal processor (ISP), which will replace the partially custom designs of its predecessors, which relied on modified Samsung ISPs with Google-designed blocks. Google is also expected to use a custom memory controller, system-level cache and power modules. Third-party solutions will be sourced for USB, PCIe, and I3C components as well as third-party interfaces for the DSI (display), DisplayPort, flash storage and memory (LPDDR5x).<\/p>\n It is also worth noting that the same table that details the Tensor G5 chip also mentions a mysterious custom Xiaomi chipset, going by the name XuanJie, that is said to use an Imagination Technologies GPU.<\/p>\n
