Using the B-X version yields a combined hashrate in the range of 838 to 841 on two radeon hd 7850s (pitcairn), up from 825-828 on b6, so about a 10h/s improvement or ~1,6% increase.
After an uptime of 7 hours, 425 good shares and 0 bad shares have been found.
Total hashrate for gpu0 is approximately 413,96 h/s (this has a 1440p display plugged into it) and for gpu1 is 426,39 h/s (no display).
Oc gpu0: 1230 core, 1420 mem.
Oc gpu1: 1205 core 1432 mem.

The following launch parameter was used with miningpoolhub

Code:

jce_cn_gpu_miner64.exe --mport 3336 --stakjson --keepalive --forever --no-warmup --no-cpu -o stratum -u user -p password --variation 15 -c config.txt

. Omitting '--no-warmup' yields a very unstable hashrate.

The config.txt had to be slightly changed for the B-X version. Previously this config was used:

Code:

"gpu_threads_conf" : 
[ 
     { "mode" : "GPU", "worksize" : 8, "alpha" : 64, "beta" : 8, "index" : 0, "multi_hash":432 },
     { "mode" : "GPU", "worksize" : 8, "alpha" : 64, "beta" : 8, "index" : 0, "multi_hash":432 },
     { "mode" : "GPU", "worksize" : 8, "alpha" : 64, "beta" : 8, "index" : 1, "multi_hash":432 }, 
     { "mode" : "GPU", "worksize" : 8, "alpha" : 64, "beta" : 8, "index" : 1, "multi_hash":432 },
],

but on the newer version this config yields a better result

Code:

"gpu_threads_conf" : 
[ 
     { "mode" : "GPU", "worksize" : 8, "alpha" : 64, "beta" : 8, "index" : 0, "multi_hash":416 },
     { "mode" : "GPU", "worksize" : 8, "alpha" : 64, "beta" : 8, "index" : 0, "multi_hash":432 },
     { "mode" : "GPU", "worksize" : 8, "alpha" : 64, "beta" : 8, "index" : 1, "multi_hash":432 }, 
     { "mode" : "GPU", "worksize" : 8, "alpha" : 64, "beta" : 8, "index" : 1, "multi_hash":432 },
],

Furthermore, there's a 1-4 h/s difference between using multi_hash:416 on thread 1 on gpu0 (multi_hash:432 on thread 2), and using multi_hash:416 on thread 2 (multi_hash:432 on thread 1) on gpu0. Overall, from this very brief testing, the B-X version seems better than b6 on these gpus. Thank you for your hard work and time!
Edit: Forgot to mention, the driver used is Adrenalin Edition 18.6.1
