27" Full HD All-in-One Business PC

The Dell OptiPlex 7770 integrates a 27-inch 1920 x 1080 IPS InfinityEdge display with an Intel UHD Graphics 630 controller. It is built for office environments that need a compact, single-unit workstation running Windows 10 Pro. The system includes a USB keyboard and mouse for immediate deployment.

Octa-Core i7-9700 Sustained Performance

The 9th Gen Intel Octa-Core i7-9700 operates at a 3.0 GHz base frequency with eight cores and eight threads for parallel workloads. 8 GB of DDR4 SODIMM memory supports multitasking across business applications. A 512 GB M.2 SSD handles the operating system and active files, while a 1 TB hard drive provides bulk storage capacity.

Upgrade Path From Dual-Core or HDD Systems

This configuration replaces older all-in-one PCs limited to dual-core processors or mechanical hard drives alone. The jump is worthwhile when users need faster boot times, responsive application loading, and the ability to keep large local datasets on the secondary 1 TB drive. It is not suited for buyers who require discrete graphics performance or memory beyond 8 GB.
