SiFive releases the latest RISC-V architecture processors P870 and X390 with a 50% increase in peak single-threaded performance

Thanks to CTOnews.com netizen OC_Formula for the clue delivery! CTOnews.com October 12, RISC-V chipmaker SiFive announced the launch of two new products, the SiFive Performance P870 CPU and the SiFive Intelligence X390 NPU processor.

According to reports, the P870 processor is suitable for high-performance consumer applications or in combination with vector processors in data centers. The P870 is a six-wide out-of-order core with a peak single-threaded performance improvement of 50% (specINT2k6) compared with the previous generation of SiFive Performance series processors, meets RVA23 requirements, and provides shared cluster cache to support up to 32-core clusters.

In addition, the P870 is fully compatible with Google's platform requirements for Android on RISC-V. P870 also provides other SiFive features that have been verified:

RISC-V vector of 128b VLEN length (RVV)

Vector encryption and Hypervisor extension

IOMMU and Advanced interrupt Architecture (AIA)

Non-inclusive (non-inclusive) tertiary cache

Validated RISC-V WorldGuard security design

The SiFive Intelligence X390 uses a single-core configuration, double vector length and double vector ALU, which increases vector computing performance by four times and persistent data bandwidth by four times compared to the X280. With the SiFive Vector Coprocessor Interface extension (VCIX), users can add their own vector instructions and / or accelerate hardware design. CTOnews.com attached product features include:

1024 bit VLEN, 512 bit DLEN

Single / double vector ALU

VCIX (2048 bits output, 1024 bits input)
