An older example is when FIA imposed F1 team limits on CFD simulation time in TFLOPS * t.
Of course multiple teams paid extra for a funky CPU SKU with gimped TFLOPS numbers and ran at low clock speed (↓ memory latency in cycles) with cores disabled (↑ cache per core) to maximize CFD performance per TFLOP.
At least one person proposed a custom machine with 0 TFLOPS to work around the limit, but this was rejected as too risky because the result would be too absurd, a la https://en.wikipedia.org/wiki/Brabham_BT46#Brabham_BT46B_%E2%80%93_the_fan_car
