Indeed, heat is my biggest enemy. I've long since blown out the heat sink / fan on this loser. It only manages to keep limping along with the USB powered laptop cooler attached. I suspect the same would be true for other laptops as well. My next company supplied laptop will be a Lenovo, though not a y580 (sadly).

Incidentally, I'm using Pentoo from portage overlay (not the live builds), but updated more or less daily. The latest available (test) build from Gentoo for john is "1.7.9-r5", though john reports somewhat differently.

I didn't see additional hardware details like RAM and SSD vs. HDD mentioned, but those will obviously have some impact on overall performance. On the other hand, they're "just" benchmarks so have to be viewed with some distrust, anyway.

I see you have used 4xOMP - I should've noted I ran the cpu benchmarks
on just one core. Silly of me I know, since we're talking about what
speed we can actually pull out of those machines .. That would explain
the differences. Since the tests are being run entirely in memory the
disk speed doesn't change anything. But for the record its a standard
laptop 5400 rpm drive, and I have 8 gb ddr3 ram.
Here's the lotus test (on 1/4/8 cores/threads):
Benchmarking: Lotus Notes/Domino 5 [8/64]... DONE
Raw: 451675 c/s real, 456192 c/s virtual
Benchmarking: Lotus Notes/Domino 5 [8/64]... (4xMPI) DONE
Raw: 1704K c/s real, 1721K c/s virtual
Benchmarking: Lotus Notes/Domino 5 [8/64]... (8xMPI) DONE
Raw: 3227K c/s real, 3227K c/s virtual
Benchmarking: Lotus Notes/Domino 6 More Secure Internet Password
[8/64]... DONE
Many salts: 90820 c/s real, 90820 c/s virtual
Only one salt: 53788 c/s real, 53788 c/s virtual
Benchmarking: Lotus Notes/Domino 6 More Secure Internet Password
[8/64]... (4xMPI) DONE
Many salts: 345597 c/s real, 345597 c/s virtual
Only one salt: 206224 c/s real, 206224 c/s virtual
Benchmarking: Lotus Notes/Domino 6 More Secure Internet Password

Many salts: 677244 c/s real, 677244 c/s virtual
Only one salt: 402405 c/s real, 402405 c/s virtual
And the other tests I did yesterday, this time on 8 threads (i7 has 4
cores with HT)
Benchmarking: M$ Cache Hash 2 (DCC2) PBKDF2-HMAC-SHA-1 [128/128 AVX
intrinsics 8x]... (8xMPI) DONE
Raw: 4182 c/s real, 4182 c/s virtual
Benchmarking: M$ Cache Hash MD4 [32/64]... (8xMPI) DONE
Many salts: 116829K c/s real, 116829K c/s virtual
Only one salt: 47149K c/s real, 47149K c/s virtual
Benchmarking: MS SQL SHA-1 [128/128 AVX intrinsics 8x]... (8xMPI) DONE
Many salts: 79225K c/s real, 79225K c/s virtual
Only one salt: 49717K c/s real, 49717K c/s virtual
Benchmarking: NTLMv2 C/R MD4 HMAC-MD5 [32/64]... (8xMPI) DONE
Many salts: 5339K c/s real, 5339K c/s virtual
Only one salt: 4356K c/s real, 4356K c/s virtual
... as you see, mscash2 speed is about the same as on the CUDA. This
really surprised me here. Also, everyone's all-time favorite hashing
function, I like the pretty numbers:
Benchmarking: Raw MD5 [128/128 AVX intrinsics 12x]... (8xMPI) DONE
Raw: 148364K c/s real, 148364K c/s virtual
