Build a capable budget gaming PC with the Intel Core i5-9400F 9th Gen Processor. Featuring 6 cores, up to 4.10GHz Turbo frequency and 9MB Intel Smart Cache, it delivers solid gaming and everyday performance when paired with a dedicated graphics card.

The Intel Core i5-9400F is a 9th Generation Coffee Lake Refresh desktop processor designed to deliver strong value for gaming and everyday computing.

Featuring 6 physical cores and 6 threads, the i5-9400F provides solid multi-core performance for gaming, office applications, multitasking and general productivity.

It operates at a 2.90GHz base frequency and can reach up to 4.10GHz Max Turbo Frequency, providing responsive performance when games and applications require additional processing power.

With 9MB Intel Smart Cache and support for DDR4 memory, the i5-9400F is an excellent foundation for an affordable dedicated-GPU gaming PC.

Important: Dedicated Graphics Card Required

The “F” designation means the Core i5-9400F does NOT include integrated graphics.

A compatible dedicated NVIDIA GeForce or AMD Radeon graphics card is required to get display output from a PC using this processor.

This makes the i5-9400F particularly suitable for gaming systems where a dedicated GPU will already be installed.
