    Firebat F1 Mini
    Bundle: 24GB RAM 512GB SSD


    after $60 discount on 1st November you get this for $291.26, RIDICULOUS PRICE.

    The 24GB is LPDDR5 quad (similar to DDR5 dual channel). I was promoting the GMKtek k12, which has a faster GPU but the prices for DDR5 RAM are like $100 for 8GB so I was only going to use a single channel. this 24GB dual channel is far superior in terms of actual performance because it's not chocking the GPU. it's also LPDDR5 so it's lower power RAM, the CPU is slightly faster than the K12 also!

    here is a review of it but in russian

    Обзор мини-ПК Firebat F1: работа над ошибками или даунгрейд?
    Крепкий середнячок на повседнев. Примерно так ощущается мини-ПК Firebat F1. Есть за что похвалить, есть за что поругать. Но в...

    key take aways

    1. The Soldered LPDDR5 Performance (The "Quad-Channel" Boost)
    The reviewer ran AIDA64 and verified that the memory is indeed soldered LPDDR5 operating in four-channel sub-mode (which functions as standard dual-channel).
    Review Data: The memory benchmark pulled ~92.5 GB/s write speeds.
    What this means for you: This confirms that the Firebat F1 completely avoids the memory bandwidth choke of a single stick. That ~92 GB/s pipeline is exactly what the Radeon 760M needs to handle complex rendering, dual-layer FEL files, and AI dynamic tone mapping effortlessly.


    2. Cooling Architecture & Thermal Mass
    The review highlights the internal structural layout of the machine:
    Airflow intake: The review notes that the cooling fan pulls cool air directly from the bottom mesh intake and exhausts it out the side.
    What this means for you: You must not place this mini PC directly on a thick rug or inside a completely closed cabinet where the bottom rubber feet sink. If you keep the bottom clearance open, this cooling setup is massive overkill for a 15W capped profile. It will run cool and remain completely silent in your media room.


    3. Power Supply (Over-spec Efficiency)
    The reviewer noted that the device ships with a beefy 120W power adapter (19V / 6.32A), stating that the CPU draws significantly less than what the power brick is capable of delivering.
    What this means for you: When you use ryzenadj to restrict the processor to 15W, the total system wall draw will likely hover around 22–25W total. Because a 120W power supply is running at less than 25% capacity, the power brick itself will remain cool, operate efficiently, and easily absorb any brief system spikes without breaking a sweat.


    4. The Real-World Verdict (The "Middle-Tier" Advantage)
    The reviewer summarizes the Firebat F1 as a "solid middle-of-the-road worker". It doesn't break world records, but it lacks major system flaws.
    The only true complaints in the article are the uninspiring speeds of the factory 512GB SSD (~2400 MB/s) and the lack of a secondary front Type-C port. For a dedicated LibreELEC boot box, SSD sequential read speeds don't matter at all—Kodi reads media file streams at a maximum of ~15–20 MB/s (150 Mbps for high-bitrate 4K remuxes).

    Final Thoughts
    This teardown confirms the Firebat F1 is an excellent candidate for your project. The dual-channel memory bandwidth is real, the cooling assembly is sturdy, and the hardware handles media tasks elegantly.

    for our use case, this is way better and cheaper than the K12, to get 16GB of DDR5 in K12 will cost you $200 by itself!
    you have to make sure you stay up the time when coupons are released, each day they allocate only certain amount, then restart the next day. once added, they remain in basket till expire (full month). Damn what a machine for $291.

  • Damn should have checked. On the same link I posted I thought it was greyed out on the other option, it wasn't, I just had to change to 16GB (LDDR5)

    you get only 16GB, you probably only need 4GB for LibreELEC. the SOC is far more capable Ryzen 7 H255. it's like TOTAL COST $307.74 (after $60 discount), you guys might have cashback sites.
    I just checked and it says only 1 left, though not sure if they mean it. this is a better device but the other one was overkill also. so pick this if stocks else pick other

    Quote

    I received it without any problems. It works well and the power cord is of the Korean type. Windows 11 Pro is installed and has been authenticated. The RAM consists of four 4GB Samsung RAM modules. M.2 SSD is 512GB with 3.0.




    The Ryzen 7 H255 is 122% faster in single-core CPU speed and roughly 300% faster in GPU performance than the Ryzen 5 3500U. (assuming single DDR4 for 3500U system)

  • i tested CroqueMr build with Amd Deskmini A300 with Amd 3400g cpu.

    tested short with 3-4 fel movies, dv fel works like it should be. any other format (hdr10+ didn't test).

    maybe you can grab this old device for cheap

    it's far far bigger than the firebat, also even barebones it's like $240 used, it will be far noiser, you better of with the $291 system I gave. It's very cheap for the hardware, Dev was recommending 3500U for around $220, and you most likely only get single channel DDR4 with that system at that price, which is enough but limits the GPU at half the speed, the firebat has full dual channel and it's Low power RAM , so it's ideal here, it's 2.6x the single core speed and 3x the GPU (single vs dual)

    Idle power in windows is only 5.2W, on LibreELEC its probably lower?

    AI is saying the H 255 has officially lowest TDP at 15W if you want. inside Firebot bios we can set the TDP, and AI is saying setting it to 12W will not affect single core performance, but will multi core. but we should expect zero frame drops
    At a strict 12W processor limit, the Firebat F1 will be practically silent, with a noise level settling below 25 dBA
    also will help longevity by running so low. could experiment and see what works. These Mini PC's are lower power than S928X? if you configure them

  • Hi all,
    I appreciate the suggestions here. I’m especially looking for a passively cooled/fanless option to use that has a bit more overhead than an n150. Any suggestion in that regard which be future proof with regards to DV conversion and/or higher framerates? Thanks!

    What's your budget? Aliexpress deals are tonight, check my previous posts. that's as high end as you can get , it will be virtually silent and you can change the TDP to like 12W in bios and change fan curve to turn on when it hits like 55 degrees. it would be silent. it depends on where you live, since I can't get that box in UK and have the GMKtek K12 as an offer instead. the K12 is much beefier cooling design. I think both will be silent as hell, but first what's your budget, have you shopped in aliexpress before and where in world you live like in the USA?


    So It seems you get an extra $60 offer!

    Your True Total Savings:

    • Automatic Discount: -$60
    • Manual Code (USD1160): -$60
    • Total Discount: $120 off

    he $60 off you are already seeing on your screen is the automatic "Spend & Save" or store discount. The image shows code USD1160, which is a Multi-store coupon that you can enter manually at checkout to get an additional $60 off, because your order is $367 (which satisfies the $339+ requirement).

    Your True Total Savings:

    • Automatic Discount: -$60
    • Manual Code (USD1160): -$60
    • Total Discount: $120 off

  • I am in US, yea. Budget is about $300ish but considering waiting for Black Friday “proper” in terms of exclusively passively cooled options. I can go a bit less hardware grunt if it will still have enough overhead. Basically wondering if something like n300 (or AMD equivalent) would be good enough in that regard, as I’ve seen some fanless models with that one (though usually pricier as a result ofc).

    & I know from experience that I am *extremely* sensitive to even the least fan noise, ha, especially when watching something. I have an n150 Protectli machine I use for proxmox, Opnsense, etc. now and it has spoiled me (only has hdmi 1.4, though, so not the best for this use case).

    Also no knock on Aliexpress but I have not shopped there before, no. I will certainly consider your previously posted option though, thanks!

    the DV stuff should be fine playing, some conversions might be close or over the capabilities. something comfortable is like the 3500U, I can't find anything like that in finless. CroqueMr will have to chime in. I still think the firebat I mentioned above will be fanless , just set the fan curve high, so trigger it at 55 degrees. run it at eco mode of 15W. the system is supposed to handle like 54W and when watching movies the GPU won't even sweat, you also have LPDDR5. box is beefy to. if you share how you intend to use it, dev could advise on what platform his software will handle. also maybe he thinks the firebat will also be quiet. there are ways to later mod to the box if it comes to it. I have reason to believe the requirements will get lower so a fanless N150 probably could do it, but very close. consider getting the firebat cheap on offer, then checking if it works like I think it will. if it doesn't, sell on ebay for profit . will be worth a $100 more than you pay for it

  • Deal is up for the K12 if you live in UK
    $210.79

    Pay with pay pal, to get $11 off. barebones, get RAM for £60 on ebay. £157.34 is a crazy cheap price for this barebones

  • I know this is a hot time. Developers are preparing Dolby Vision software for RC1, and Black Friday deals are coming.

    So I allow shopping links for a limited time, but only from experienced users. I probably delete those links later.

  • I have a question regarding audio output:

    My LG TV only supports (E)AC3 :dodgy: - my Logitech Z906 supports AC3 & DTS, no HD/lossless audio !

    Options:

    a) Geekom A5 Pro –> HDMI 1 – LG TV – S/PDIF – Logitech Z906. Disadvantage: no DTS (1.5 Mbit/s), only AC3 (640 kbit/s). I think Kodi can convert DTS-HD Master or Dolby TrueHD to AC3 5.1 640k ?

    b) Geekom -> HDMI 2 -> HDMI adapter to S/PDIF –> Z906; DTS/AC3 support. is this possible? HDMI1 -> Video with DV; HDMI2 -> Sound?

    c) USB soundcard with 6-channel analog –> Z906 (analog connection). Advantage: lossless PCM 6-channel output for TrueHD / DTS-HD. Potential drawback: interference/noise due to the analog cable.

    edit

    d) USB S/PDIF adapter like this - but supports linux/Kodi it?

    any ideas?

  • Here is a short benchmark to give you an idea of how two small CPUs perform. Take a look at the specific circuits you're interested in. I’ve included a table covering the GUI, it’s not a huge deal for me personally, but apparently some people really hate experiencing frame drops when a Kodi graphical element is on screen. (these aren't the subtitles, it is Kodi overlay)

  • awesome work CroqueMr . mostly issues with 60fps. They not uniformly better on one particular platform. It seems it's universally GPU bound, the CPU has lots of breathing room. Probably no one would really tell the missed frames BUT it goes to show neither platform will handle everything at these GPU performance. getting a faster than 3200U actually should give you better fluidity. btw I didn't mention but I also love your info graphs on your github



    very nice work!

    Just want to finish and say there is value to go much past a 3500U, who knows what other things Devs might add (you including) having more headroom is worth it I think. People were willing to pay allot of money to even get AM6B+ which is poor performance, I think something like a 5300U or above would fix this. right now the hardware isn't expensive, as I've listen above $282 machine will give you zero dropped frames (Ryzen5 7640HS)
    anyway great work as usual. hope you don't burn out, you've been full throttle for 6 weeks

  • Thanks for the kind words,

    Yes 60fps is difficult to render, but the two most important circuits are perfectly stable on the two small CPU : Master Reference & DV to HDR10 Expert. I’ve spent the most time optimizing them, if I have a bit less support work to do, I could push the optimization further for the rest, but it will not be a game changer
