Details of what is claimed to be Google's upcoming Tensor G5 and G6 SoCs have popped up over on Notebookcheck.net and the site claims to have found the specs on a public platform, without going into any further details. Those that were betting on the Tensor G5—codenamed Laguna—delivering vastly improved performance over the Tensor G4, are likely to be disappointed, at least on the CPU side of things. As previous rumours have suggested, the chip is expected to be manufactured by TSMC, using its N3E process node, but the Tensor G5 will retain the single Arm Cortex-X4 core, although it will see a slight upgrade to five Cortex-A725 cores vs. the three Cortex-A720 cores of the Tensor G4. The G5 loses two Cortex-A520 cores in favour of the extra Cortex-A725 cores. The Cortex-X4 will also remain clocked at the same peak 3.1 GHz as that of the Tensor G4.

Interestingly it looks like Google will drop the Arm Mali GPU in favour of an Imagination Technologies DXT GPU, although the specs listed by Notebookcheck doesn't add up with any of the specs listed by Imagination Technologies. The G5 will continue to support 4x 16-bit LPDDR5 or LPDDR5X memory chips, but Google has added support for UFS 4.0 memory, something that's been a point of complaint for the Tensor G4. Other new additions is support for 10 Gbps USB 3.2 Gen 2 and PCI Express 4.0. Some improvements to the camera logic has also been made, with support for up to 200 Megapixel sensors or 108 Megapixels with zero shutter lag, but if Google will use such a camera or not is anyone's guess at this point in time.

Arm has announced a pair of new Armv9 CPU cores today, alongside a refresh of a third. The new additions are the Cortex-X925—which is a huge model number jump from the previous Cortex-X4—and the Cortex-A725 which should be an upgraded Cortex-A720. Finally the Cortex-A520 has been refreshed to bring a 15 percent power efficiency improvement as well as support for 3 nm production nodes. Arm claims that the Cortex-A925 delivers its highest performance improvement ever over a previous generation with a single core uplift of up to 36 percent and an AI performance improvement of up to 46 percent compared to the Cortex-X4. The Cortex-X925 will support up to 3 MB private L2 cache and is tape-out ready for 3 nm production nodes.

The Cortex-A725 is said to offer a 35 percent performance efficiency improvement over the Cortex-A720 and it's been given performance boosts both when it comes to AI and gaming workloads. It's said to be up to 25 percent more power efficient than the Cortex-A720 and L3 cache traffic has been improved by up to 20 percent. Again, the Cortex-A720 is ready for production on a 3 nm node. Finally, Arm has also updated its DynamIQ Shared Unit to the DS-120 and here Arm has managed to reduce the typical workload power by up to 50 percent and the cache miss power by up to 60 percent. The DSU-120 scales to up to 14 Arm cores, suggesting that we might get to see some interesting new SoC implementations in the coming years from Arm's partners, although Arm's reference platform is a 2-4-2 configuration of the new cores.
