Performance Comparison
When it comes to raw performance, the Intel Core i5-12400F outshines the HP FAST EliteDesk 800 G3 SFF PC. The i5-12400F boasts a base frequency of 2.5 GHz, while the older i7 6th Generation in the HP PC can reach speeds up to 4.00 GHz. However, the i5 processor is part of Intel's 12th generation, incorporating advancements in technology that enhance efficiency and multitasking capabilities. The HP desktop offers 4 cores, which might initially seem competitive, but the architectural improvements and support for PCIe 5.0 and 4.0 in the i5-12400F can lead to superior performance in modern applications.
Price Analysis
In terms of price, the HP FAST EliteDesk 800 G3 SFF PC is more affordable at £139.99 compared to the Intel Core i5-12400F, which is priced at £148.87. This makes the HP PC an attractive option for those looking for a budget-friendly solution without compromising too much on performance. However, it's essential to consider that the i5-12400F is a standalone processor, while the HP is a complete system. Thus, while the initial investment in the HP is lower, long-term value may favour the newer Intel processor, especially for tasks demanding higher processing power.
Memory and Storage
The HP FAST EliteDesk 800 G3 SFF PC comes with 16GB of DDR3 RAM, providing ample memory for multitasking and running multiple applications simultaneously. In contrast, the Intel Core i5-12400F does not include RAM, indicating that users will need to invest in additional components to build a complete system. Moreover, the HP desktop offers options for either 512GB or 1TB of SSD storage, ensuring quick boot times and efficient access to files. The combination of high RAM and fast storage in the HP PC makes it suitable for users who require a reliable desktop for everyday tasks.
Operating System
The HP FAST EliteDesk 800 G3 SFF PC runs on Windows 11 Pro, giving users access to the latest features and security enhancements. This modern operating system supports various applications and provides a sleek user interface that can improve productivity.

For users prioritising wireless connectivity and multiple display setups, the HP offering is clearly the better choice.
Form Factor and Design
The HP FAST EliteDesk 800 G3 SFF PC features a compact Small Form Factor (SFF) design, making it an excellent choice for those with limited desk space. This design does not compromise performance, allowing it to deliver full desktop capabilities while saving space. The Intel Core i5-12400F, being a processor, does not have a physical form factor or design elements to compare. Users seeking a sleek and space-efficient desktop will find the HP model aligns perfectly with their needs.

Intel is renowned for its cutting-edge processors that power a wide range of computing devices. The i5-12400F is a testament to this reputation, featuring the latest technology advancements.
