Bottleneck by resolution
Same engine as the builder. At 1080p the CPU does more of the work; at 4K the GPU carries the load, so the verdict changes with your monitor.
The verdict, in full
Written from this pair's own engine output: the score, the bottleneck direction and the resolution it changes at.
This is a pairing to fix before you buy. The engine scores the balance at 78 out of 100 at 1080p, and the reason is blunt: the Ryzen 5 5500 bottlenecks the RTX 4070 12GB. You would be spending card money and then strangling it with the processor.
The gap shows most at 1080p and 1440p, where the CPU does more of the frame work. Here the RTX 4070 12GB spends a good part of its time waiting on the Ryzen 5 5500. At 4K the score recovers to 89 because the load shifts onto the card, but very few people buy a GPU at this level to play at 4K on a budget CPU.
The fix is not a bigger PSU or faster RAM, it is a CPU one or two tiers up. Check what your board socket supports before you assume that upgrade is available later, because on some platforms it is not.
Real-world performance
What this pair is built to handle. These are engine-derived tiers, not benchmarked figures. I will not print an FPS number I cannot source.
Who this is for
Skip this pairing if
- You care about getting your money's worth out of the GPU
- You game at 1080p or 1440p, which is the worst case here
Instead
- Keep the RTX 4070 12GB and move up to a stronger CPU on the AM4 socket
- Or keep the Ryzen 5 5500 and step down to a card that matches it
Finishing the build
Common questions
Opens the builder with both parts loaded. Swap either side and watch the score move before you spend anything.
