We’ve been tracking the rise of RISC-V considering the fact that the ISA debuted approximately a decade ago. Even though the greatest-executing RISC-V CPUs are nevertheless far behind their x86 or ARM equivalents, the absolute degree of performance you can get from a RISC-V core is raising swiftly. Even superior, specifically for these who like experimenting with new architectures, the value is coming down.
It is been achievable to acquire a RISC-V board before this, but the choices have been limited, especially for the revenue you’d invest. We mentioned an pricey SiFive selection final yr — a quad-core chip, in that case — but there is now a a great deal more cost-effective Beagle board choice.
The CPU is a twin-core U74 developed by “StarFive” — you can see the label down below — but the U74 is a SiFive CPU main. StarFive and SiFive use the exact symbol, implying a marriage among the two. The corporation may do small business less than both of those names or have spun off aspect of its chip progress group. Irrespective, the U74 core is prevalent to both this $119 BeagleV and the additional-costly Hive Unmatched platform we covered back in 2020. Attributes contain:
- VIC-7100 RISC-V dual-main at 1.5GHz with 2MB L2 cache.
- Eyesight DSP Tensilica-VP6
- NVDLA motor (2048 MACs @ 800MHz)
- Neural community engine (1048 MACs @ 500MHz)
The board expenses $149 with 8GB. H.264 and H.265 decode are both equally supported, as is 1080p @ 30Hz refresh charge output more than HDMI. There are 4x USB 3. ports, a Gigabit Ethernet port, and 802.11b/g/n wi-fi. There is also a 40-pin GPIO header, as you can see:
There are two variations on the way. The very first, shipping and delivery quickly to fanatic backers, lacks committed video hardware and only ships with 8GB of RAM. The next will supposedly function a GPU by PowerVR alongside with open up supply drivers. It’ll ship in two flavors — a $119 4GB variant and an 8GB variant, at $149. These afterwards boards are expected to swap to a new SoC, trading out the VIC-7100 for the VIC-7110. This will be a quad-main SoC, with the aforementioned focused video clip components.
It is good to see RISC-V selling prices coming down and we’ll be curious to see if the open ISA starts choosing up lovers in the client room. Raspberry Pi is definitely the 800-pound, $35 gorilla in the space, but a honest quantity of corporations have released very similar Do-it-yourself items with increased price tag tags than the RBP and correspondingly greater characteristic sets.
The U74 is reported to have effectiveness similar to a Cortex-A55, so do not hope miracles from the diminutive chip, but prime-finish overall performance on RISC-V is bettering nicely, calendar year to year. If any ISA is heading to set up by itself as a substantial-effectiveness (broadly construed) substitute to ARM or x86, it appears to be like like it’ll be RISC-V.
