Small update: I now have dual-core SMP with a CoreMark > 2, without an L2 cache. Pretty damn cool.

Added CoreMark scores and FFmpeg FPS (among with many other attributes you need the instance itself for, such as GPU architecture/temps/wattage and memory speed) to instances.vantage.sh 😀
(ffmpeg fps is the first min of big buck bunny transcoded from 4k to 1080p)

Experimenting with a Risc-V build of coremark. Interestingly, it runs about 5% faster (although my Arm build was with gcc 10 and the Risc-V build is with gcc 14 so it might not be an entirely fair comparison).

I'm running the coremark benchmark on both cores as the test that it's running OK.
As for how we're overclocking it, we have been playing with a couple of options:
- using the ring oscillator which automatically goes faster as you reduce temperature / increase voltage

What 32-bit #microcontroller (i.e., Cortex-M or RV32, not a Linux application processor) has the highest Coremark/mW, or lowest uA/MHz? A quick search suggests Ambiq Apollo 4 or ST STM32U3, but are there others I should look at?
