HP OmniDesk Slim Desktop vs HP ProOne 440 G9 All-in-One

The ProOne 440 G9 is the stronger machine: a 16-core i7-13700T, 16GB of RAM and a 23.8-inch screen built into one unit. The OmniDesk Slim is a small, light tower with a 10-core i3-14100 and 8GB, and you supply your own monitor. Buy the OmniDesk if you want a compact, low-power box for browsing, streaming and office work and already own a screen. Buy the ProOne if you want one device for the desk, more CPU headroom and Windows 11 Pro.

  • Choose the OmniDesk Slim if you want a small, light desktop that fits under or behind a monitor you already own and your work is streaming, email and documents.
  • Choose the ProOne 440 G9 if you want an all-in-one with the screen included, a much faster 16-core processor and double the memory for heavier multitasking.

What reviewers say

HP OmniDesk Slim Desktop

  • 4.4 / 5449 ratings

Rated 4.4 out of 5 from 449 ratings, buyers generally find the OmniDesk Slim quick for daily tasks and easy to set up. Complaints center on the modest 8 GB of memory and limited room to upgrade.

What people mention
  • PerformancePraisedOwners say it feels fast for browsing, email and streaming.
  • MemoryCriticisedReviewers note 8 GB of RAM runs short with many browser tabs or large photo libraries.
  • SizePraisedBuyers like the slim, light chassis that fits tight desk spaces.
  • ExpandabilityCriticisedOwners mention few options to add drives or a graphics card later.

HP ProOne 440 G9 All-in-One

Owner feedback on the ProOne 440 G9 line is generally positive, with buyers calling it a dependable, quiet office machine with a good screen and easy setup. Complaints tend to focus on the integrated graphics and the modest upgrade room rather than day-to-day performance.

What people mention
  • PerformancePraisedOwners say the Core i7 keeps up with many browser tabs and office apps without lag.
  • NoisePraisedThe low-power T-series chip keeps the fan quiet in everyday use.
  • DisplayPraisedReviewers like the bright 23.8-inch Full HD IPS panel and its viewing angles.
  • GraphicsCriticisedBuyers note the integrated UHD 770 graphics are weak for gaming or heavy creative apps.

Questions and answers

Which is better for office work and multitasking?
The ProOne 440 G9. Its 16-core i7-13700T and 16GB of RAM keep more apps open smoothly, while the OmniDesk's 4-core i3 and 8GB suit lighter loads.
Do I need a monitor with the OmniDesk Slim?
Yes. The OmniDesk is a tower only and ships with a keyboard, not a screen. The ProOne includes a 23.8-inch Full HD IPS touchscreen.
Which lasts longer?
Both use solid-state storage and have no moving parts to wear out. The ProOne has more CPU and memory headroom, so it should stay useful longer for demanding work; the OmniDesk's 8GB is the first limit you will hit.
Is the ProOne worth stepping up to?
Yes if you need a screen and heavier multitasking, since it bundles the display, doubles the RAM and adds a much faster processor. The OmniDesk makes more sense if you already own a monitor and want a small, efficient box.
Can I upgrade the memory later?
The OmniDesk uses DDR5 and the ProOne uses DDR4, so check the open slots before buying. The ProOne lists one slot pair; the OmniDesk's 8GB is the main spec to raise.
Which is better for gaming?
Neither is a gaming PC. Both rely on integrated Intel graphics, so plan on light or older titles only.
