msi Cubi msi Cubi 5 Premium Compact Desktop, 12th Gen Intel Review
The MSI Cubi 5 mini desktop boasts Thunderbolt 4 and triple 4K support in a tiny box, but its mobile processor holds back its value for most users.
The 30-Second Version
The MSI Cubi 5 is a premium compact desktop with a killer feature set for connectivity, including Thunderbolt 4 and triple 4K display support. However, its mobile-class CPU performance is underwhelming for the price, and it's not meant for gaming. It's a niche pick for users who value a tiny footprint and multiple monitors above raw power.
Overview
If you're hunting for a compact desktop PC that doesn't take up half your desk, the MSI Cubi 5 is worth a look. This little box packs a 12th Gen Intel Core i7-1255U processor, 16GB of RAM, and a 1TB SSD into a chassis that weighs less than six pounds. At around $700, it's positioned as a premium mini PC for home office and general use. And with Thunderbolt 4 and support for triple 4K displays, it's trying to punch well above its weight class in terms of connectivity.
Performance
Let's be clear about what this is. The Intel i7-1255U is a 10-core mobile processor, and our database puts its CPU performance in the 26th percentile versus all desktops. That means it's fine for office work, web browsing, and light multitasking, but don't expect it to chew through heavy video encoding or complex data analysis. The real star here is the integrated Intel Iris Xe Graphics, which somehow lands in the 97th percentile. That's because it's paired with a massive 48GB of shared VRAM, making it surprisingly capable for driving multiple high-resolution monitors. For actual gaming, though, our score is a harsh 22 out of 100. You're limited to older titles or esports games on low settings.
Pros & Cons
Pros
- Incredibly compact and lightweight design 97th
- Outstanding port selection, including Thunderbolt 4 91th
- Can drive three 4K displays simultaneously 89th
- Includes Windows 11 Pro, which is a nice bonus
- Low power draw and quiet operation
Cons
- CPU performance is mediocre for a desktop at this price 25th
- Absolutely not for gaming
- Only 16GB of RAM, which is below average for the category
- Reliability scores are just middle-of-the-pack
- The 1TB SSD is decent, but not exceptional

Value & Pricing
At $699, the Cubi 5 sits in a weird spot. You're paying a premium for the mini form factor and the Thunderbolt 4 port. If you don't need that extreme compactness, a similarly priced traditional desktop tower would give you a much more powerful CPU, more RAM, and often a dedicated GPU. But if desk space is at a premium and you need to connect a ton of high-res peripherals, this starts to make sense.
vs Competition
The most direct competitor is the Intel NUC series, but they often cost more for similar specs. If you want more power in a small box, the ASUS ROG NUC gaming mini PC is a beast, but it's also over twice the price. For most people, a better value might be a small form factor tower like the Lenovo ThinkCentre M series, which offers better upgradeability. The Cubi 5's main trick is its combination of tiny size and massive display/output potential, which is hard to find elsewhere.

Common Questions
Q: Is the MSI Cubi 5 good for gaming?
No, it's not. With integrated graphics and a mobile CPU, it scores a 22/100 for gaming in our tests. You'll be limited to very basic or older titles.
Q: Can the MSI Cubi 5 run three monitors?
Yes, it can support triple 4K displays at 60Hz using its HDMI, DisplayPort, and Thunderbolt 4 outputs, which is one of its biggest strengths.
Q: How does the MSI Cubi 5 compare to an Intel NUC?
It's very similar, often offering comparable specs at a slightly lower price point. The Cubi 5's main advantage is its included Windows 11 Pro and excellent port selection right out of the box.
Q: Is the RAM upgradeable in the MSI Cubi 5?
It likely is, as most mini PCs have socketed RAM, but you'll need to check the specific model and be comfortable opening the compact chassis.
Who Should Skip This
Skip the Cubi 5 if you need serious computing power for video editing, 3D rendering, or gaming. Also, if you don't care about the tiny size and don't need to run three 4K monitors, your money is better spent on a standard desktop tower with a more powerful CPU and dedicated graphics. Look at something like the HP Pavilion or Dell Inspiron desktops in the same price range.
Verdict
Should you buy the MSI Cubi 5? Only if your needs are very specific. This is a fantastic machine for a kiosk, a digital signage setup, or a super-clean home office where you need to run three 4K monitors but only do basic computing tasks. For anyone else, the CPU is a letdown for the money. We'd only recommend it if the mini form factor and triple 4K output are non-negotiable for you.
