The box a local model runs in is not the lid on the laptop

TORONTO — October 4, 2026

A laptop lid is two purchases welded together: the pane you look at, and the computer that has to hold the model. This morning’s guide was the pane. This one is the computer. The run does not need the keyboard bolted to the glass. It needs a working set that fits, and a box that is still there when the lid has moved.

The cards under this story are affiliate links. If you buy through them, Artificial Examiner may earn a commission. We have not bench-tested these mini PCs. There is no speed figure in this piece, because this desk did not time a model on any of them.

The lid is a computer you can close. The model wants a box that stays where you left it, and enough DDR5 to hold the file it is actually running.

What the lid is bad at

The glass on the lid is one pane. That was this morning’s monitor guide. Close the lid, or let the machine treat a closed lid as idle, and the job stops or goes where you cannot see it. A mini PC on the desk has no lid to close. The pane is a separate object. The box is the other one.

The worse limit is memory you cannot change. A lot of thin laptops solder LPDDR and offer no SODIMM slot. The working set of a GGUF is system RAM. That was yesterday’s memory guide. A sticker that says 16 GB on a soldered machine is the size of the machine. It is not a starting size. Disk holds the file, on the internal SSD or on the portable shelf filed yesterday. RAM holds the working set. A faster shelf does not add a gigabyte the loader can use.

The 780M is not a graphics card you can buy

The three listings below are AMD Ryzen HS machines whose pages name Radeon 780M graphics. The processor names on those pages are the Ryzen 7 7840HS, the Ryzen 9 7940HS, and the Ryzen 7 8845HS. The graphics description on each page says integrated. None of the titles is selling a discrete GPU, and none of these pages is a card slot you fill later.

On this class of chip the processor and the graphics use the same DDR5. A loader that keeps every layer on the CPU spends that DDR5. A loader that hands layers to the 780M spends the same DDR5. llama.cpp and Ollama can be pointed at a graphics device when the machine exposes one. Offload does not create a second pool. It moves work onto a slice of the pool you already bought. A firmware screen that assigns part of the memory to graphics is carving that part out of what the operating system can see. It is not a module you add, and it is not video RAM on a card these listings do not include.

Treat the next paragraph as the same planning arithmetic as yesterday, not as a timed test from this desk. For a dense model, a 4-bit GGUF lands on the order of half a gigabyte per billion parameters. An 8-billion-parameter quant is a few gigabytes. A 32-billion-parameter quant is in the high teens of gigabytes. A 70-billion-parameter Q4 file is on the order of 40 GB. Those are file sizes. The machine also holds the operating system, the loader, and a cache that grows with the prompt. Sixteen gigabytes can hold a small quant if the rest of the desktop is quiet. Thirty-two is where a 32-billion-parameter quant becomes a plan. A 70-billion-parameter Q4 file does not fit in 32 GB of system RAM. Sixty-four is where that larger quant and the rest of the desktop can share a pool. More RAM stops the swap. It does not add a discrete graphics card.

A mixture-of-experts file does not shrink to the active parameter count. A loader that pulls the whole file into memory holds every expert. Buy the box for the window you intend to open, not only for the GGUF on the disk.

A SODIMM is the upgrade these boxes can take

Yesterday’s cards were DDR5 SODIMMs, the short modules a laptop uses. A mini PC that takes those modules can take that upgrade. A mini PC that solders LPDDR cannot. The three titles below do not say soldered LPDDR. Read the lines that say what the memory is. Then read the manual for the board you actually receive. A listing and a chassis can disagree, and this desk has not opened these cases.

The internal drive named in the title is the shelf for the file you are loading today, which is the job yesterday’s disk guide gave the machine’s own SSD. The portable drive is still the library. A label that says 1TB is still not 1,024 GiB of free space. None of that changes the RAM.

These are desk machines with their own power, not laptops hanging off a monitor port. The USB-C watt ceiling in this morning’s monitor guide is about charging a laptop from the pane. It is not how these boxes are fed.

What the three cards are

Other mini PCs exist. These cards are only the three listings we can attach to a real Amazon Associates tag, threadandfade-20. We are not ranking them against each other or against any machine we cannot link. There is no price in this piece.

One card is the Beelink SER8 Mini PC, Ryzen 7 8845HS 64G DDR5+1TB NVMe PCle4.0 x4 M.2 SSD | Win11 Pro, WiFi6/ BT5.2/2.5GLAN/NPU, HDMI+DP+USB4 Triple Display MAX 4K 144Hz, Radeon 780M 12 Cores 2700MHz Mini Computer. The short name is the Beelink SER8. “PCle” is the spelling in that title. The title is doing the listing’s work: Ryzen 7 8845HS, 64G DDR5, 1TB, Win11 Pro, and Radeon 780M at 2700MHz. It also prints NPU. The page does not say the NPU holds the GGUF. The memory table is still the DDR5.

The product-information table lists the RAM type as SODIMM, installed RAM as 64 GB, and a maximum of 256 GB. It does not print a slot count. The color field says White/8845HS/64/1T, which is the same 64-and-1TB pair as the title. A bullet says the processor operates at 3.8 GHz to 5.1 GHz. The CPU model speed maximum in that table says 4.9 GHz. The display lines on the same page do not agree either: one bullet includes HDMI2.0 among the video outputs, and a ports line says HDMI2.1. We did not open the case, and we did not time the chip. The graphics table lists the graphics RAM type as SODIMM, the same word the memory table uses for the system RAM. The graphics description says integrated, and the bullet names the Radeon 780M. We are not reading that SODIMM label as a second bank.

When this desk opened the Beelink SER8 listing on 4 October 2026, the page said the item was currently unavailable. That line is inventory. It will move. It is not a spec.

The second card is the Beelink SER7 Mini PC, AMD Ryzen 7 7840HS(Up to 5.1GHz) 8C/16T, Mini Desktop Computer 32GB DDR5 RAM 1TB NVMe SSD, Small Gaming PC Support 4K@144Hz Output/BT5.2/WiFi 6 for Gaming/Office/Home. That is the Beelink SER7. The title says Ryzen 7 7840HS, 32GB DDR5, and a 1TB NVMe SSD. A bullet says dual-channel 32GB SO-DIMM DDR5, upgradeable to a maximum of 64GB as 2 x 32GB, and a 1TB M.2 SSD. It does not say whether the 32 GB already in the box is one module or two. Two slots and a 64 GB ceiling are what that bullet is claiming.

A later block on the same page says SO-DIMM DDR5 at 5600MHz in a 16/32GB line, and storage of 500GB. The title says 1TB. The capacity bullet says 1TB. That later block says 500GB. The product-information table lists installed RAM as 32 GB, a maximum of 64 GB, two memory slots, and a memory clock speed of 4800 MHz. A memory-speed field on that table says 2 MHz. We are not choosing among those figures. The graphics coprocessor line says AMD Radeon 780M. The graphics RAM type field says GDDR6. The graphics description says integrated. We are not treating GDDR6 in that field as a module this listing sells. The page said currently unavailable on 4 October 2026. Same reading as the other card: inventory, not a spec.

The third card is the MINISFORUM Venus Series UM790 Pro Mini PC AMD Ryzen 9 7940HS(8C/16T, up to 5.2GHz) 64GB DDR5 1TB PCIe4.0 SSD Micro PC, 2xUSB4(DP|8K)/ 2xHDMI(4K)/ Intel Killer WiFi 6E/ BT5.2/ 4xUSB3.2 Mini Tower PC. The short name is the MINISFORUM UM790 Pro. The title says Ryzen 9 7940HS, 64GB DDR5, and a 1TB SSD. A description table says DDR5 dual channel, two SODIMM slots, up to 5600MHz, maximum 64 GB. The product-information table agrees on that shape: 64 GB installed, DDR5, a 64 GB maximum, and two memory slots. A bullet says the 64GB has been preinstalled, but that you could expand the RAM to 64GB. Expanding to the size already in the title is not a larger machine. Two slots already at the table’s maximum do not take a third stick, and they do not become 128 GB because a different mini PC on some other page says a higher number.

The graphics coprocessor line on the UM790 Pro page says AMD Radeon 780M and a graphics frequency of 2800MHz. The Beelink SER8 title says 2700MHz. A hundred megahertz between two listings is not a test this desk ran. The graphics RAM type field says GDDR6. Same reading as on the Beelink SER7 page: a label on an integrated part, not a discrete card.

The model-number and model-name fields on that UM790 Pro page say DeskMini. The title says UM790 Pro. We are carding the title. We are not treating DeskMini as the product. When this desk opened the listing on 4 October 2026, the page said the item was currently unavailable.

Which listing to read for which pool

Choose the Beelink SER8 when the title you want already says 64 GB, and when the table’s 256 GB SODIMM maximum is the ceiling you are willing to plan around. The table does not say how many slots that 256 GB is supposed to occupy. Read the manual before you order a kit from yesterday’s memory guide and assume it seats. The letters NPU in the title are not a second memory pool.

Choose the Beelink SER7 when 32 GB is the working set you are buying today, and when the bullet’s two SO-DIMM slots and 64 GB maximum are the upgrade you want later. That upgrade is a SODIMM. It is yesterday’s article, not a graphics card. Do not choose this listing on the strength of a 1TB title if you needed the description block and the title to agree. They do not. We did not open the drive bay.

Choose the MINISFORUM UM790 Pro when the title you want is the Ryzen 9 7940HS with 64 GB already installed, and when two SODIMM slots at a 64 GB maximum is a machine you do not intend to grow. If that table is right, the sticks in it are the whole pool. Replacing them does not get you past 64 GB on the number that page prints.

Do not choose on a clock we did not measure, or on a graphics-RAM field that says GDDR6 or SODIMM while the chip line says integrated Radeon 780M. Do not choose because a review on the page liked a game. The cards are the listings. Artificial Examiner has not opened these boxes, has not loaded a GGUF on them, and has not seated a module in them. The blurbs under the story say that in shorter form.

The buttons under the article go to those three Amazon listings with our Associates tag, threadandfade-20. They are advertisements. The commission, if a purchase happens, does not pick the working set. The DDR5 you intend to hold the model in does.
