Ryzen 5 8400F vs Core i7-11700F
Compare the Ryzen 5 8400F and Core i7-11700F on real gaming and productivity benchmarks, full specifications, live retailer prices and performance-per-dollar, then jump straight to the cheapest in-stock option.
The short answer
The Ryzen 5 8400F is the better buy here: it's both faster for gaming and gives more performance per dollar.
- Ryzen 5 8400F is about 3% faster for gaming at 1080p (gaming index 50.0 vs 48.5).
- Ryzen 5 8400F is the cheaper chip right now, by roughly 114%.
- Ryzen 5 8400F delivers about 121% more gaming performance per dollar.
- Core i7-11700F has more cores (8C/16T vs 6C/12T), which helps in heavily threaded workloads.
Gaming performance
CPU-bound gaming score: a geometric mean of in-game frame rates at 1080p, normalized so the fastest gaming CPU we track = 100.
Does the CPU matter at 1440p or 4K? Much less. At higher resolutions the graphics card sets the frame rate, so the gap between two CPUs shrinks — often to nothing. The 1080p figure above is the demanding case, where the CPU is stressed and the difference actually shows.
Performance per dollar
Gaming index divided by the current lowest price — higher is better value. This moves with the market as prices change day to day.
The Ryzen 5 8400F gives about 121% more gaming performance per dollar at today’s prices.
Full platform cost
A complete-platform price needs a live CPU price and an in-stock compatible motherboard on both sides. We can’t build one for Core i7-11700F right now, which is common for older sockets like AM4 where we don’t track current boards. The gaming, value and specs comparisons still apply.
