A not well tuned attack on gpu can make the gpu seem to be slow.
And my point with alienware is that it's quite expensive for the stuff you really get.
I agree with you about the alienware, I was just making a point regarding the comparison! it was strange to me that on that article they are actually recommending a mobile radeon over the Nvidia thats in the alienware knowing that mobile GPUs tend to be slower.
I did benchmark and I think the MD5 gave the following results:
workload: 1024 loops, 256 accel
speed GPU1: 1075.9 MB/s
speed gpu 2: 1074.8 MB/s
speed gpu.#*: 2158.7 MB/s
I also did an actual test of trying to crack one md5 hash with a 146 million wordlist (i made the hash uncrackable as per to the wordlist) when running with gpus I get the attempt done in 10 secounds while it only take about 2 to 5 seconds through cpu.
I thought wordlists are not the best for gpu cracking so i tried the same with pure bruteforcing but achieved the same results
