Common questions.
Straight answers on the i5-11400F versus the Ryzen 5 3600.
Is the i5-11400F better than the Ryzen 5 3600?
Yes, but by less than the spec sheet suggests. At 1440p the i5-11400F scores 63 against 57 for the Ryzen 5 3600 — roughly 11% faster.
Does the i5-11400F or Ryzen 5 3600 bottleneck a RTX 3080?
Paired with a RTX 3080 at 1440p, the i5-11400F build comes out 2% CPU-bound, and the Ryzen 5 3600 build comes out 5% CPU-bound. Being GPU-bound is the healthy outcome — it means the graphics card is the part working hardest.
Is it worth upgrading from the Ryzen 5 3600 to the i5-11400F?
Only if you are also lifting the rest of the build. The i5-11400F is about 11% ahead at 1440p, and gaps like that shrink further at 4K where the GPU does more of the work. If you are upgrading from the Ryzen 5 3600 purely for frames, check the pairing first.
Which is better value, the i5-11400F or the Ryzen 5 3600?
On performance per dollar at MSRP, the i5-11400F wins. The i5-11400F lists at $157 for an index of 63, and the Ryzen 5 3600 at $199 for 57.
