My old 4800U (8 core / 16threads) laptop is playing up and it's 16 Gig of RAM is severely limiting my CAD work now.
so, i'd committed myself to buying a desktop.

I'd settled on a basic 8700G based Ryzen system with 64 Gig of RAM. (the G has basic graphics built in, ain't interested in anything else!)
a SINGLE CORE benchmark of 3917 on one site………

This is a nice 50% increase on my 4800U lapop which has a score of 2564

** EDIT - For a similar price / Performance INTEL / conventional motherboard system, closest competitor would be the $400 I5-14600K, it beats this by 2-3 points in single core and multi core Geekbench, but system MAX power is at least 3x more**

here's a nice 'CPUbenchmark' comparison of a few
https://www.cpubenchmark.net/compare/3721vs5232vs5036vs5031v…

Now, where the 'deal' bit comes in..
The equivalent single core performance AMD 7700X / 8700G processors come in at around $500 AUD……,

I figured, my minimum investment's gonna need to be around $1500ish (8 core chip with a 4060) to get any drastic improvements over my laptop
Picking budget items on PC Part Picker AU gets me to about $600 (plus post) for a 8700G, motherboard and CPU Cooler! - the same as this board.
BUT………..
this board has 50% higher multi core performance! (as it has double the cores!)

If you compare laptop processors - this one's THIRD
https://www.cpubenchmark.net/laptop.html

with an overall benchmark that sits at the lower end of HIGH range desktops!

So, Summary, after all that waffle.

Spending $640 right now, gets me 16C/32T processor with basic integrated graphics
I'd need to get an $830 7950X to match the number of cores and a minimum of $1000 on a mobo/cooler deal……..(and an old second hand GPU from somewhere)
it's about 14% faster in multi core, and 5% faster single core

EDIT -
Paired this with 64GB Kingston Fury 5600 CL 40 DDR5 RAM @ $299 from JW (cheaper on Amazon @ 275, but 2 weeks till delivery)
(these IGPU's are very RAM timing dependant, you get a LOT more performance with better RAM!)

and with a Cooler Master modular power supply - MWE V2 750W power supply @ $115

Total invested now is $640 + $430 = $1070……..
add any old case and i'm in for $1k

AND….I can always add a big beefy GPU later on!

    Yes but that is comparing laptop processors lol you're not buying a laptop.

    This is a Mini ITX PC, you'll be limited on what graphics card size you can put in.. if you can at all.

    A prebuild with 4060 is much better value

      An iGPU with >32GB shared memory is one of the only "affordable" ways to run bigger LLMs locally. So as always it depends on use case and YMMV. Not that I would pick this one either.

      • Commodore64 on 20/02/2025 - 10:39

        If it's AMD, good luck running LLMs at all with ROCM. With LLMs of that size inference might not even be a token per second.

          Yeah like I said, I wouldn't pick this one either.

    • bleugh on 20/02/2025 - 09:27

      Define 'Value'?

      yes, it's THIRD in laptop processors.
      it also pretty much matches the DESKTOP 7950X

      I've just gone through this excercise. it's NOT.
      Spending $800 all in, with some memory, a basic PSU and basic case nets me 15% less multi core performance (3% less single core) than JUST a 7950X processor on it's own!.
      I'd need to spend 50% MORE on a pre-built to obtain pretty much the same performance

      i REALLY wanted a pre-built, even had one in the cart, ready to go (8700G or 7600X )the 7700x didnt' seem worth the extra) ………
      but this thing blows them out of the water!

      it's a mini-itx motherboard with the processor embedded

      you can throw it in whatever case you want with whatever graphics card you want.

    I've seen these before while looking for a minipc but then since its barebones what do you do with it? I get need to DIY RAM/NVME drive but what about closing out the case?

    Or do you just mount this inside whatever desktop sized case you like?

    • bleugh on 20/02/2025 - 09:29

      'whatever' you fancy!
      I'll probably run it naked bolted under my desk

    Normal price, stll a bargain. I built a server/ Proxmox node with this along with 96GB of DDR5 Corsair RAM, a 2TB SSD, Inwin ITX Case w/ 200W PSU and a Noctua slim case fan and it's been running great!

      I've been resisting exactly this for weeks. I don't need more temptation…

  • SunshineKiter on 20/02/2025 - 09:34

    Could anyone comment on how much this would cost to get running with a gen 5 ssd, 96GB RAM (maximum allowed), and a PSU supporting a 300W graphics card? I have a graphics card that needs a system, so I am curious how much this would all come to in order to be functional. Cheers.

    • cheapdoodau on 20/02/2025 - 09:46

      Super rough

      Good 2tb gen5 ssd is around $350
      96gb ddr5 5200 sodimm is around $380
      SFX PSU 750w Gold is around 200
      Case 150-250
      CPU fan 30

      maybe $1200ish but cheaper if you snipe some deals
      + mobo itself

      $1850~

    • bleugh on 20/02/2025 - 09:49

      go to PC Parts Picker and find out!

      really doesn't seem like this is for you though

      64Gig FAST CL40 5600 RAM will set you back $280…., 96 Gig of slower RAM will be closer to $400
      add in a low end PSU for, say $100
      and a 1TB SSD for maybe $150

      • cheapdoodau on 20/02/2025 - 09:53

        I used a cheaper cooler master PSU once, it literally caught on fire and started pumping smoke into my room - never again. Always spend a bit more on quality PSU - IMO

      96GB RAM for $338 from Amazon AU

      CORSAIR Vengeance SODIMM DDR5 96GB (2x48GB) 5600MHz CL48-48-48-90
      CMSX96GX5M2A5600C48

      • bleugh on 21/02/2025 - 15:40

        They are a great price, I almost went for 96 gig, but settled with 64 Gig and the Kingston KF556S40IBK2-64 DDR5-5600 CL40-40-40 sticks instead. The iGPU really benefits from the first word latency reduction….

        some benchmarks (this one) have shown 20% or more difference with standard memory vs higher frequency / low CAS
        though can be a lot less!

        figured this would benefit me day-day more than 33% more RAM

        Saying that though, I did spot the KF564S38IBK2-32 which can be DDR5-6400 CL38-40-40 OR DDR5-6000 CL38-38-38, a bit faster, BUT, 1/2 the capacityso not great with only 2 slots, I really wanted that 64 Gig

    Great little mobo/cpu. In my experience these run a little hot and potentially loud, and the BIOS isnt amazing.

    Undervolting helps and try choose a quiet 120mm fan for the CPU.

    • Shadowsfury on 20/02/2025 - 11:21

      Definitely feels like a great budget option for desktop level CPU performance

  • Panpanw on 20/02/2025 - 12:16

    What is the different between BD795i SE and BD790i??

    I can see the fan and wifi are different.

    • bleugh on 20/02/2025 - 12:35

      Looks like the main difference is

      Wireless - AX1675 + Cable on the 790I
      M2 slot on the 795i

      so, no wireless on the cheaper model!

      • JonnyCookieDough on 20/02/2025 - 12:37

        the pcie 5.0 m.2s is the big part and the m.2 cooler that comes.

        • bleugh on 20/02/2025 - 12:40

          BE795i SE without SSD heatsink and SSD fan connector, without internal antenna adapter (IPEX U.FL MHF4 Coaxial Pigtail Cable)

          from their webpage!

  • pedeyet762 on 20/02/2025 - 21:52

    So there is no chipset on the motherboard? Does that mean you only have 24 pcie lanes total here compared to 36 with cpu + b650 and 44 with cpu + x670? Seems like quite a compromise for expandability (10g nic, nvme adapters, usb cards etc).

    • Nom on 20/02/2025 - 22:44

      It's an ITX board - you only need enough lanes for the 16x slot and the pair of M.2 slots.

    • bleugh on 21/02/2025 - 07:44

      it has 2 x PCIe 5.0 x4 slots 1 x x16 slot
      2.5G ethernet onboard
      2 x USB2.0 Type A
      2 USB 3.2 Gen 2 Type A
      can do 3x 8k displays -
      1 HDMI 2.1 (still not very common, most are on 2.0)
      1 Displayport 1.4
      1 USB-C (alt DP)
      PCIE Bifurication

      So, for a grand, all in, you can have a 64Gig 16 core / 32T 'monster' that benchmarks just outside of the top 100 processors available

      It trades blows witht the 11% faster Core Ultra 9 275HX - and the Core i9-13980HX, 13% slower

      check Geekbench charts!, at 2743 for single core, the top intel device sits only at 3134 -
      Single core matches the Ryzen 5 7500F, Intel Core i9-13900, Intel Core i7-14700 and is close to the Intel Core i5-13600KF (a range of $350-$500 Processors)
      Multi Core - sits at 15945…
      The top intel device sits comfortably higher at 21659……
      But, this trades blows with the threadripper PRO 5955WX (i'll leave you to figure out the cost)
      DESKTOP Ryzen 9 Pro 7945 (a $1000 processor!) or the i5-14600K ($500 on it's own)

      So, closest competitor would be the $400 I5-14600K, it beats this by 2-3 points in single core and multi core
      Add in a $180 motherboard (with 2.5 gigabit LAN) , memory ($280 64 gig DDR 5 5600 CL40 ) and power supply……..

      and, it's a similar price to this thing………and a similar perfomance………with a 4x power draw!
      so, yeah, it's not for everyone, but it's a Blimmin good deal
