sci five announced the pair (opens in new tab) new high-performance RISC-V (opens in new tab) The processor is targeted at what is being called the “next generation of wearables and smart consumer devices.” Known as the P670 and P470, the processors offer new features and improved performance compared to previous CPUs based on popular open source architectures.
SiFive Performance P670 and P470 #RISCV processors bring unmatched computing performance and efficiency to wearables, smart home applications, AR/VR devices, and more.

Virtualization is supported, including a separate IOMMU for accelerating I/O for virtualized devices and a full out-of-order vector implementation based on the RISC-V Vector v1.0 specification approved last year. increase. The chip claims to be the first on the market to support the new RISC-V vector encryption extensions. The company has also talked about his 128 cores in the past, but it also shows enhanced scalability by working together clusters of up to 16 cores.
SiFive’s 600 Series Is Performance-Oriented — The P650, The Forerunner Of The P670 (opens in new tab) Performance was expected to match the Arm Cortex A-77, but the 400 series is a more efficient chip.The P550 is a perfect match for Intel’s Horse Creek dev board, which combines RISC-V with DDR5 RAM and PCIe 5.0. It was a nice tip. Intel Tried To Acquire His SiFive For His $2 Billion Around This Time Last Year, But The Deal Fell Down (opens in new tab) After the enterprise could not agree to the terms.
The P670 is built on a 5nm process and is capable of achieving maximum clock speeds of over 3.4GHz. SiFive’s description sounds like a P650 with two additional vector units. The new chip aims to beat Arm’s design in a performance-per-mm metric that measures the space a chip occupies relative to its processing power.
The P470 is designed as a companion chip to the P670 and we expect it to come in a big.LITTLE configuration, exactly like Arm chips use in smartphones and tablets. It’s also designed at the 5nm node and reaches the same clock speeds as its big brother, the P450 is also present. This lacks a single vector unit in his P470 and is area optimized especially to fit in tight spaces.
“The P670 and P470 are specifically designed to handle the most demanding workloads of wearables and other advanced consumer applications. It delivers strong performance and compute density to enterprises that are looking to grow,” said Chris Jones, vice president of products for SiFive. “We have optimized these new RISC-V Vector-enabled products to deliver the increased performance and efficiency that the industry has long sought.”
There is no news about when the P670 and P470 will be available or which companies will use them.
