It's a motherboard with high performance CPU integrated, like a desktop 7950X grade and uses the exact same basic graphics. For playing games, you need to add your graphics card.

That 7945hx has a cinebench R23 score of 15kish. Performance is VERY limited as a 7950x. The iGPU is about 30% performance of 78xx's 780m. I ordered the 7940x version and returned. It has a clear and limited use case. It's not a replacement for high performance desktop.
You can just add your graphics card. Didn't you check the integrated graphics spec before purchasing. The idea here is not a mini-pc with powerful integrated graphics but build a desktop using that motherboard. Advantage is small form factor and cheaper price. Ryzen 9 7950X CPU + b650 motherboard + cooler will cost a lot more.

What are you talking about? This very item has a review on amazon showing an R23 score of 33k? Seems like a very good setup for an itx build. Integrated graphics don't matter- if someone needs more than just a display out they can add any graphics card they want (provided it will fit in their itx build)

BD790i SE used to be on front page months ago but is now sold out. Better value for the same core count and only slightly lower frequency.

That is definitely true but all the Reddit forums, from where I got the information 1st and posted here, mentions that Minisforum only made very limited numbers. The main difference is PCIe Gen5 support on this one for both SSD slots vs Gen4 in the SE model.

This is purely a workstation board unfortunately. It has some oddities (for size) that IF you are going to put it in a small case you will need to use a SFF (low profile) graphics card which are normally professional. Then you put it in a normal or smaller case, you can just use a normal CPU solution. It also doesnt have any SATA ports for drives so you either have to sacrifice an NVMe or the only PCIx slot to expand there. This uses SO-DIMM for memory, etc. So NAS use case not really unless you sacrifice the PCIx w/ a SAS card..

Minisforum track record and availability for BIOS updates is also an issue. I had a 2 week support case to resolve a sleep issue and they wanted me to take drastic measures (like wipe everything out multiple times) when reverting back one BIOS fixed the issue -- however unlike most OEM they only have the current BIOS up not the history so you have to go though the middle of the night support (they are in China) and the days it takes to get a resolution. Note: In this case I had to force support they were pretty unhelpful so unless you are very technical I would also think twice from the support angle.

Value wise this is very good, use case is very limited IMHO, and since it is integrated then you also can't upgrade the CPU later. The GPU in this is gimped meant for 2D solutions, so this misses the mark on gaming unless you add a GPU and at that point a discrete solution is around the same price and upgradable in any dimension.

I did look at this heavily for a while, but I decided to build my own a few weeks ago w/ a discrete solution because I did not need SATA ports as this was my main PC. I can see this if you don't need lots of storage tho.

The concept is that it is cheaper. You are not going to get a Desktop solution, CPU + Motherboard + Cooler of this caliber at the price of this whole board. This CPU is just 10 to 15% Slower than 7950X Desktop CPU while consuming just 100W of power. Ryzen 9 7950X will alone cost you around $450. And 2ndly, there are plenty of very small cases, supporting pretty big Graphic cards and for those builds, this is perfect. I agree, it is not for everyone but it is not just a workstation board.

Like any modern laptop CPUs, it has a boost TDP which is 100W and in this board, it can maintain that for pretty long time, reaching around 85-90% of desktop 7950X, while consuming a lot less power under load.

Interesting, I want to get ahead of tarrifs and am wondering whether it makes sense to build around this. I don't really game at the moment but want to keep that option for later. I currently run a RX 5700 XT in a build with an older CPU and slow RAM, would this board take that graphics card? I would like the option to pot. upgrade to a 5XXX Nvidia eventually. Does one of you know whether that is
possible and if so, is there an itx case that you can recommend that takes big graphic cards?

Yeah as a reference I did look at this board hard and decided to get 7900x for $299, asrock b650m hdv for $100 and the cooler for $34. So that is $439 so around the same, however the TDP and speed is not up to par, its single threaded is faster and I had more I/O. My largest hesitancy however was the concern over Minisforum support and prior experience (poor) w/ both Beelink and Minisforum so that I passed.

But on paper this is a great package 100%.

I have this CPU in my Lenovo Legion laptop. It's a beast. Yes, 54K on Passmark!

Integrated graphics get the job done, but you should add a separate graphics card to this board if you're going to do any gaming.
