HP EliteOne 840 G9 2024, Core i7-14700, 16GB, 512GB SSD, Silver

The HP EliteOne 840 G9 is a business all-in-one desktop with a powerful 20-core i7-14700, 16GB of DDR5, and a 512GB SSD. It's great for office multitasking and comes with HP's full security suite, but the integrated graphics are weak and the storage is small for the price. Buy it for clean, secure productivity work, not for gaming or creative tasks.

The Core i7-14700 is the star here. It's a 20-core chip (8 performance cores, 12 efficiency cores) with a 2.1GHz base clock, and it lands in the 82nd percentile for CPUs in our database. That's well above average for all-in-ones, and in practice it means this machine chews through spreadsheets, browser tabs, video calls, and light photo editing without breaking a sweat. The 16GB of DDR5 helps too, though it's right around the middle of the pack for RAM in this category.

The weak spot is graphics. The Intel UHD Graphics integrated GPU sits in the 14th percentile, which is a polite way of saying it's near the bottom for anything GPU-intensive. You can run a second monitor, handle 1080p video playback, and do basic productivity work without issues. But don't expect to edit 4K video smoothly or play anything beyond the most casual games. The 512GB SSD is also on the smaller side, landing in the 31st percentile for storage. It's fast, but you'll likely want external or cloud storage if you keep a lot of large files locally.

Stacked against the Lenovo Legion Tower 5a Gen 10, the EliteOne 840 G9 looks like a different species. The Legion is a gaming tower with discrete graphics and far more raw performance, but it's a big box that needs a separate monitor. The HP wins on desk footprint and the touchscreen, but loses badly on GPU performance. If you need any kind of graphical horsepower, the Legion is the obvious choice.

The Apple Mac Studio M3 Ultra is in another league entirely for creative work and compute-heavy tasks, but it's also not an all-in-one and runs macOS. The Dell Area-51 is similarly a high-performance tower aimed at gamers and creators. The EliteOne 840 G9 isn't trying to compete with those machines. It's competing with other business AIOs and compact desktops, where the i7-14700 and HP's security suite are the differentiators. The Horizon Pcs Autherium Dragon and CLX SET are gaming-focused builds that make the HP look underpowered on paper, but again, they're not solving the same problem.

At $2,029 USD, the EliteOne 840 G9 is a tough sell on pure specs alone. You can get a tower desktop with similar or better internals for less money, but you'd lose the all-in-one form factor, touchscreen, and the enterprise security features. The value proposition here is really about simplicity and manageability. For a business that wants a fleet of machines that are easy to deploy, secure, and take up minimal space, the premium makes sense. For an individual buyer, it's harder to justify unless the touchscreen and compact design are must-haves. Alternatives like the Lenovo Legion Tower 5a Gen 10 or even a Mac Studio M3 Ultra offer dramatically more performance per dollar, though they're different form factors entirely.

The HP EliteOne 840 G9 is a business-focused all-in-one desktop that sits in the premium tier of office machines. We're looking at a 23.8-inch touchscreen AIO with a 14th Gen Intel Core i7-14700, 16GB of DDR5, and a 512GB SSD. It's the kind of machine IT departments buy in bulk, but it also shows up on desks of people who just want a clean, capable Windows 11 Pro setup without a tower cluttering their floor.

At around $2,029 USD, this isn't a budget pick. You're paying for the all-in-one form factor, the touch display, and HP's enterprise security stack. The question most shoppers are asking is whether the EliteOne 840 G9 is good for everyday office work and multitasking. The short answer is yes, the i7-14700 is a serious processor for this class of machine. But the integrated Intel UHD Graphics means this is absolutely not a gaming rig, and the storage is on the modest side for the price.

HP positions this as a secure, manageable business machine. Wolf Security, Sure Sense, Sure Click, and Sure Recover are all baked in. For a small office or a remote worker who wants a no-fuss Windows 11 Pro desktop with a touchscreen, it's a compelling package. For anyone who needs discrete graphics or expandability, you'll want to keep reading.

Skip the EliteOne 840 G9 if you need any real graphics performance. Gamers, video editors, 3D modelers, and anyone who wants to run multiple high-resolution displays should look elsewhere. The integrated Intel UHD Graphics are simply not up to those tasks. Also skip it if you're a value-focused buyer who doesn't need the all-in-one form factor. A tower desktop like the Lenovo Legion Tower 5a Gen 10 or a custom build will give you far more performance per dollar. And if you're deep in the Apple ecosystem, the Mac Studio M3 Ultra is a much more capable machine for creative work, though it's a different form factor and OS entirely.

Should you buy the HP EliteOne 840 G9? If you're outfitting an office or want a clean, secure, touchscreen all-in-one for productivity work, yes, it's a solid choice. The i7-14700 is a genuinely strong processor, the build quality is typical HP business-grade, and the security features are a real benefit for anyone handling sensitive data. The 4.5-star customer rating from early buyers backs up the idea that people who buy this machine are happy with it.

But if you need any kind of graphics performance, want more storage, or are buying for personal use where every dollar counts, this isn't the machine for you. The integrated GPU is a real limitation, and 512GB fills up fast. For the same money, you could build or buy a much more capable tower setup, assuming you have the desk space and don't need the touchscreen.
