Is exponential growth of desktop computing power not valid anymore? Today, it looks more like a logarithmic growth.
For example, at the beginning of 1990th a typical desktop CPU was 20..50 MIPS (386,486), then in 2000 it was 1000..3000 MIPS (Pentium III, Athlon), but now they are 10000..40000 MÌPS only (Quad/Dual Cores). It means between 1990 and 2000 we've seen 100-times growth, but between 2000 and 2010 it was only 10-times growth per 10 year.
The same holds if we compare GFLOPS per Chip. In the 1992 Intel 486DX was 0.03 GFLOPS, in 2000 PentiumIII was 2 GFLOPS, and now 2010 most desktop CPUs are of 20..30 GFLOPS.
Now, let's look at the non-volatile storage: <40Mbyte at 1990> vs. <10Gb at 2000> vs. <1000Gb at 2010>. So, 1000-times vs. 100-times growth per decade.
Moreover, a volatile storage: <2Mb at 1990> vs. <256Mb at 2000> vs. about 2Gb (or more, but not 20!) at 2010. So it gives 100 vs. 10-fold growth per decade.
Does this empirical evidence means that the growth of the desktop computing power becomes slower?
