In Figure~\ref{fig:time_bbs_gpu} we highlight the performances of the optimized
BBS-based PRNG on GPU. On the Tesla C1060 we
-obtain approximately 1.8GSample/s and on the GTX 280 about 1.6GSample/s, which is
+obtain approximately 700MSample/s and on the GTX 280 about 670MSample/s, which is
obviously slower than the xorlike-based PRNG on GPU. However, we will show in the
next sections that
this new PRNG has a strong level of security, which is necessary paid by a speed
