Sophgo SG2380 – A 2.5 GHz 16-core SiFive P670 RISC-V processor with a 20 TOPS AI accelerator

Sophgo SG2380 is an upcoming 2.5 GHz 16-core RISC-V processor based on SiFive Performance P670 cores and also equipped with a 20 TOPS AI accelerator using SiFive Intelligence X280 and Sophgo TPU that will find its way into a $120 desktop-class mini-ITX motherboard in H2 2024.

The RISC-V processor also supports up to 64GB RAM, as well as UFS 3.2 and SATA 3.0 storage, comes with an Imagination GPU for 3D graphics and a VPU capable of 4Kp60 H.265, H.264, AV1, and VP9 video decoding, plenty of interfaces, and the system can manage locally deployed larger-scale LLMs like LLaMA-65B without the need for external NVIDIA or AMD accelerator cards.

Oasis mini-ITX motherboard

Oasis SG2380 mini ITX motherboard
Oasis motherboard layout

While the SG2380 SoC will be used for various applications,  I expect a range of computers, mini PCs, and laptops considering the geopolitical situation between the US and China, the first platform based on the 16-core RISC-V processor will be the Oasis motherboard.

Oasis specifications:

  • SoC – Sophgo SG2380 16-core RISC-V SoC as described above
  • System Memory – Up to 64GB 128-bit LPDDR5 5500MT/s
  • Storage
    • Pluggable UFS module
    • microSD card for OS booting and data
    • M.2 M-Key socket for NVMe SSD (PCIe 3.0 x4)
    • 4x SATA ports for HDD and/or SSD

  • Expansion
    • PCIe x16 slot with PCIe Gen 3 x8 signal
    • 8x DIO, 2x CAN Bus
  • Dimensions – 17 x 17cm (Mini-ITX form factor)

As you can see from the lack of photos of the board, development is still at the early stage, and the processor and motherboard are only expected in about 9 months (Q3/H2 2024), so I’d assume things may still change a bit, especially for the board.

But if you feel somewhat adventurous, you can already pre-order your Oasis motherboard from Arace for just $0.10 which will give you a coupon code for a 20% discount, or a starting price of starting $120. A few more details may also be found in the announcement.

The board looks pretty good. Would make a nice NAS. I wonder which hd audio they are using and if that will have linux drivers.

It says 5-30w, i wonder if they mean 5w when idle. 30w is quite a lot, more than many would like for a nas.

Yeah, have NAS always tiptoed up to 20 TOPS LLM? Maybe you’re upscaling your ColecoVision and Pippin speedruns through an AI upscaling texturing, but also deepdreaming a Shrek continuity? Also you use 10 64bit cores for stuff involving 6 cameras? But not h.265 encode. Bit of a media completist, there. GMI goes canvassing?

16 cores + gpu, 30 watt is not very much, as a nas it would use 5w i think.

Now that’s starting to be interesting with 12×2.5GHz cores. I’m confused about the DRAM though, the SoC supports DDR4/LPDDR4 and the mobo uses LPDDR5. We’ll see when it’s available.

Make a might fine ZFS NAS, if it is available with ECC RAM.

M.2 M-Key socket for NVMe SSD (PCIe 3.0 x4) (3.938 GB/s)
4x SATA ports for HDD and/or SSD (2.4GB/sec)

Wìth a M.2 NVME SATA 3.0 Card 6 Ports  (ASM1166) that could be up to 10 hard disks, configured as RaidZ3 10 (or RaidZ2 10) which would limit the read performance to that of a single hard disk (but that could still be more that enough to fully saturate both network links).

It’s almost 2024 and people still spread this silly urban myth about ZFS ‘needing’ ECC RAM 🙁

Maybe the third time will actually appear!

You never need “ECC” RAM, ever, but … (there is always a but), if you wish to measure bit flips, then you want ECC RAM. One fun example I particularly love is the higher rate of bit flips in the vicinity of cattle: https://www.jakepoz.com/debugging-behind-the-iron-curtain/

One thing to keep in mind for spinning rust and SSD that all data is stored using some form of LDPC (low density parity check) because the assumption is that every single read at the lowest level inside the device will be corrupt. Data leaving through external interfaces has been rebuilt from the corrupt low level raw data. In almost all storage some form of ECC is used. It is also used in CPU registers, L1, L2 and L3 caches.

I think this confusion emerged from all people wanting to build their NAS using ZFS and ECC, making some thinking that ZFS requires ECC. That’s not true, any FS is better protected with ECC, as it’s not fun to discover that some data were corrupted in memory after being read and checksummed, or before being checksummed and written. This FS might even check a bit more than other ones but this will not catch the classical memory corruption stuff caused by low-cost DRAM sticks or overheating RAM chips. When ECC is supported and available, for a NAS it remains a… Read more »

a former FreeNAS forum moderator who invented the ‘scrub of death’ myth: https://www.truenas.com/community/threads/ecc-vs-non-ecc-ram-and-zfs.15449/

From a support point of view though insisting on ECC RAM made a lot of sense since forcing FreeNAS users to buy expensive ‘server grade’ mainboards instead of using consumer grade crap.

Willy

As usual, people advocating full-throttle in either direction are always causing pain. I’d say that it’s always preferable to use ECC for storage, at least to avoid worrying, and there’s no reason one FS would be more or less sensitive to bit flips than others since they can happen anywhere in the chain.

With the way that modern silicon works, you either bypass blocks that do not function 100%, or develop software workarounds. A product will be shipped. There is a reason for buying previously used, tested and debugged off the shelf silicon IP blocks for SPI/UART/CPU/PCIe/eMMC/USB/GMAC/…. it is all to lower the risks involved.

Not cheaper as you have to add ram, but hell yeah I have ordered a coupon as its more Mac Mini than RK3588. 12x 2.5 GHz performance cores, 4x 1.6 GHz efficiency cores that are supposedly Cortex-A78 like in perf.

I go off what they are doing at LLama.cpp as they are doing great stuff there. Prob not https://github.com/ggerganov/llama.cpp#memorydisk-requirements which is a bit outdated but good enough for rule of thumb. Its all about how much quantisation and effect on perplexity and context windows you use. Also though loading up with a load of ram could also make this a very cost effective training platform as I may be wrong about this but you could stack the devices but need to keep in a single ram instance. 64gb for training many models is super usefull and vastly cheaper than any… Read more »

Usually you want to use a Q5K_M model that provides quality slightly above Q5_1 in a size between Q4_1 and Q5_0. It generally gives good trade-offs. Very roughly speaking you’ll need bits/8*model size + approx 10% of it for the context. So a 65B model at Q5K_M could be around 44G in operation, so it might just tightly fit in 48G RAM. In any case, it’s also interesting to consider more recent variations of these models, particularly those mixed with orca and platypus. Mistral (and its fork dolphin-2.1-mistral) is surpassing everything at only 7B but only exists at 7B, so… Read more »

[ (Thx), me reading there are ‘mixed-precision optimizer’ ((b)float16-mixed can be comparable to (b)float32’s prediction accuracy), what might improve precision, while reducing model size for training/inference. There was a number being ~1TB of data input for ~current LLMs. Probably, there’s lower expectation for reduced model sizes with demand for precision also, thus being ~10’s of GB ram for inference tasks. Another possibility seems sharing training/requests over several GPUs or TPUs? training for 16bit(FP,BF) optimizers ‘trillion-parameter model with an optimizer in 16-bit precision would ordinarily require around 16 terabytes (TB) of memory to accommodate the optimizer states, gradients, and parameters’ with… Read more »
