oclhashcat and apu a8 5500 different performances - n_lona - 12-08-2015

I have this problem launching oclhashcat64 -b i got
Code:
Hashtype: sha512crypt, SHA512(Unix)
Workload: 1024 loops, 8 accel
Speed.GPU.#1.:     1249 H/s
but if launch oclhashcat64 -m 1800 -a 3 admin.hash ?a?a?a?a?a?a?a?a?a?a? -i --incremental-min 7 --incremental-max 10 I got:
Code:
Hashtype: sha512crypt, SHA512(Unix)
Speed.GPU.#1.:     500-540 H/s
why?
Code:
DISPLAY=:0 fglrxinfo
libGL error: dlopen /usr/lib/i386-linux-gnu/dri/swrast_dri.so failed (/usr/lib/i386-linux-gnu/dri/swrast_dri.so: wrong ELF class: ELFCLASS32)

Again, pointless. Brute force attack, minimum length 7 of ?a?a?a?a?a?a?a @ 1,250 H/s (best case scenario as outlined by benchmark mode) = 95^7 / 1250 = ~1,770 years to exhaust keyspace. And you have hope of attacking length 10!?!

Well, sometimes the answer is it just can't be done with the equipment you have and move on with (a) another strategy or (b) your life.
