Thanks robish!
Once again we tied (by count). But Scott is in front because he has a bigger prime. Nothing I can fix with a GFN18 ;)

That's pretty fast, my 3080 needed 62316s.

Benchmarks are not comparable because Linux uses different numbers to test. Here are the results of the 2080:
Running on platform 'NVIDIA CUDA', device 'GeForce RTX 2080', vendor 'NVIDIA Corporation', version 'OpenCL 1.2 CUDA' and driver '455.38'.
46 computeUnits @ 1845MHz, memSize=7979MB, cacheSize=1472kB, cacheLineSize=128B, localMemSize=48kB, maxWorkGroupSize=1024.
High priority change succeeded.

Time to compare a RTX 2080 and a RTX 3080. Both GPU's are slightly overclocked ex works. The 3080 is more or less in front of the 2080. 100% in front means twice as fast:
PPS-Sieve: 27% (both GPU weren't fully utilized)
AP27: 160% (the 3080 is more than twice (2.6x) as fast !!!)
GFN-15 (OCL2): 9%
GFN-16 (OCL2): 33%
GFN-17 (OCL2): 63%
GFN-17-Mega (OCL2): 64%
GFN-18 (OCL2): 69%
GFN-19 (OCL5): 64%
GFN-20 (OCL5): 64%
GFN-21 (OCL4): 83%
GFN-22 (OCL4): 75%
GFN-extreme (OCL3/OCL5): 68% (the 2080 chooses a different transformation than the 3080)

If you plan a higher badge than MEGA....the step to 10M is to high.
Perhaps we can invent a Super-MEGA badge with 3162278 digits or more (sqrt(10) = 3.16227760...).
If a lucky person finds the first 10M digit prime in 2030 with PrimeGrid the next badge level can be opened.

You will need it87 kernel module:
https://github.com/torvalds/linux/blob/master/drivers/hwmon/it87.c
compile
load the lernel module (modprobe)
or
you have the luck that your distribution offers a repo for this....

Great! Congratulations!
First Mega in addition to the TDP. You can only top it on 29th of February with a SOB ;)
After a few DC's, finally got my first mega as primary!
Also came with both grey TDP 2020 badges :)
