    At $666, it’s not exactly compelling.

    Sure, it is faster, but I’ll still take the cheap FPGA approach.

    PicoSoC on iCE40 all the way. With an iCESugar, it doesn’t break the bank.

    I can see the value for people working on porting fundamental software, things like operating systems, programming languages or c libraries. But that’s about it.

    On the bright side, it’s cheaper and better than their previous offering, which was $1k. If this is a trend and it continues, it’ll reach sane specifications and pricing.

    1. 4

      Pricing of various options for linux capabale alt ISA:

      • PolarSOC ~ $500USD (600Mhz u540 cores, 2G Ram but get a FPGA)
      • Sifive Hi-Five Unmatched $665 USD (Unrevealed but clockspeed > 1.5Ghz, 8GB Ram, PCI-Ex8, M2 for Network and M2 For Storage and u740 Cores (not sure if these are the upgraded ones announced last month or not).
      • RaptorCS Thunderbird ~$1400USD No ram but 4 fast cores (and a probably very loud CPU cooler)
      • Orange Crab FPGA (128MB Ram, limited expansion) $130USD ~100Mhz
      • ULX3S FPGA (32MB Ram, some expansion) $130USD ~100Mhz
      • HiFive Unleased + Microsemi exapansion board (for the same capabilities as the Unmatched) $3000USD

      The new board is interesting as it’s < 25% of the cost of the previous iteration and pretty turnkey for putting together a system.

      It is of course a question as to whether to get this or wait for one more generation (ie OOO (u840?))

      (Edit: Spelling)

      1. 1

        Unrevealed but clockspeed > 1.5Ghz

        What’s your source for this?

        ULX3S FPGA (32MB Ram, some expansion) $130USD ~100Mhz

        I’ll take that. I actually ordered one, but haven’t received it yet.

        1. 2

          One of the articles mentioned they thought it would be at least that given the process they used. My apologies, I should have said that it was expected to be at least that speed.

          I am thinking about the ULX3S too as a slightly cheaper Mister but like the orange crab as it has more RAM.

          1. 1

            Unrevealed but clockspeed > 1.5Ghz

            What’s your source for this?

            u54 runs at 1.5Ghz, and this is supposed to be faster.

            1. 2

              Clock speed is only one component of performance. The 7-series micro-architecture has a higher IPC, so it’s entirely possible for the chip to be faster, even at a lower clock speed.

              We shouldn’t make any assumptions until the speed is actually announced.

              1. 1

                Well, turns out it’s 1.4GHz. FWIW the reasoning I proposed is what people on reddit were speculating, but alas, it was not to be.

        2. 3

          For me it’s interesting because I would like a RISC-V “daily driver,” and this could possibly work. But it is a lot of money.

          1. 3

            You’re likely better off waiting. The time just isn’t now.

            There’ll be more options, faster, cheaper. Possibly even open hardware (this board and chip are not).

          2. 2

            uh nice, are there more recommendations for tinkering with some FPGAs that aren’t that costly ?

            1. 4

              The aforementioned iCESugar is my advice to anyone who wants to get started with FPGAs. With peak iCE40 value/price, it uses the newest (UP5K, 5K LUT, icestorm supported) iCE40 chip, and provides 3 double-pmod (one of them shared with usbport/stm32serial) and an onboard RGB led. Embeds an stm32 µC for programming/serialport from the programming USB port. A separate USB port goes straight into the FPGA. Some jumpers can be removed to reclaim shared I/Os.

              BlackIce MX is a more serious iCE40 devboard (w/HX4K, 8K LUT on yosys/nextpnr) with lots of I/Os (incl. PMODs), and onboard RAM + STM32F7, at $65.

              ULX3S is a very high density devboard which uses a relatively powerful ECP5 (~85K LUT) at ~$130. Amazing never-seen-before value at that price, but I’m still waiting for mine to ship. As it can fit quite a bit, many miSTer cores have been ported, including the Amiga (w/020+AGA) implementation.

              Tang Nano (GW1N-1, an interesting chinese chip at ~55nm fab, supported by project apicula, which is less mature than icestorm or trellis) sells at less than $10 shipped (aliexpress). Peak value/price. The more experimental option, but already works (LUTS, flipflops and routing, stll no hard block peripherals nor dual port ram blocks) with open FPGA tooling.

            2. 7

              I’m fine with this being here, I want to know about alternative platforms.

              1. 2

                agreed. I’m very interested in tracking what’s happening with hardware platforms like this and a big part of hardware platforms is hardware releases

              2. 5

                Even though it’s great to see progress on RISC-V dev boards, not a fan of product advertising or reviews here.

                1. 4

                  I hope this submission isn’t too much like an advertisement. I was just excited to hear more about it, ever since it was announced.

                  1. 2

                    Indeed, it looks too much like an advertisement. It might have been better to just link the product brief.

                    1. 3

                      That would also be too much like an advertisement, in my opinion.
