Common questions.
Straight answers on the Ryzen 7 5700X3D versus the i5-11400F.
Is the Ryzen 7 5700X3D better than the i5-11400F?
Yes, but by less than the spec sheet suggests. At 1440p the Ryzen 7 5700X3D scores 66 against 63 for the i5-11400F — roughly 5% faster. It also costs about $92 more at MSRP, so the question is whether that gap is worth the money for your build.
Does the Ryzen 7 5700X3D or i5-11400F bottleneck a RTX 3080?
Paired with a RTX 3080 at 1440p, the Ryzen 7 5700X3D build comes out 0% CPU-bound, and the i5-11400F build comes out 2% 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 i5-11400F to the Ryzen 7 5700X3D?
Only if you are also lifting the rest of the build. The Ryzen 7 5700X3D is about 5% 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 i5-11400F purely for frames, check the pairing first.
Which is better value, the Ryzen 7 5700X3D or the i5-11400F?
On performance per dollar at MSRP, the i5-11400F wins. The Ryzen 7 5700X3D lists at $249 for an index of 66, and the i5-11400F at $157 for 63.
