For many years, Google has worked with Samsung Foundry to produce its Tensor chips. However, this may be changing with the upcoming Tensor G5, which is set to launch with the Pixel 10 series. A recent leak from Google’s gChips division, shared by Android Authority, suggests that Google will use TSMC’s advanced 3nm process for the new chip, which could lead to better efficiency and performance.
Changes in CPU and GPU Design
One of the most notable updates in the Tensor G5 is its redesigned CPU architecture. Unlike the previous Tensor G4, which offered only a small performance boost, the G5 retains a primary Cortex-X4 core but includes a revamped mid-cluster. The new setup features five Cortex-A725 cores, an increase from the previous three Cortex-A720 cores, while the smaller cluster has been downgraded to two Cortex-A520 cores. This change indicates that Google is trying to find a better balance between performance and power usage, although the decision to keep the Cortex-X4 instead of upgrading to the latest Cortex-X925 is quite interesting.
Innovations in Graphics Performance
The Tensor G5 also breaks away from tradition by not using the ARM Mali GPU. Instead, it adopts a new GPU from Imagination Technologies (IMG), the DXT-48-1536. This GPU adds ray tracing support, a first for Tensor chips, and includes GPU virtualization features that could improve graphics performance for gaming and other demanding tasks. While the new TPU in the Tensor G5 shows a 40% rise in TOPS (Trillions of Operations Per Second), internal benchmarks indicate a more modest 14% enhancement in real-world applications. Furthermore, the TPU now allows on-device training and incorporates embedded RISC-V cores that enable capabilities that weren’t available before, likely expanding its AI functions.
Anticipation for the Pixel 10 Series
For those eagerly awaiting the Pixel 10 series, there’s good news! The Pixel 10, expected to be released in the latter half of next year, will be the first device to sport the Tensor G5. Switching to TSMC’s 3nm process could greatly improve power efficiency, addressing previous concerns regarding the Tensor series, especially issues like thermal management and performance slowdowns. Reports suggest that Google aims to compete more effectively with Snapdragon-powered smartphones by making this strategic move, as TSMC’s manufacturing technology has been crucial for Qualcomm’s recent achievements.
In summary, these updates reflect Google’s ambitious intentions to establish the Pixel 10 series as a more formidable player in the flagship smartphone market.
