- Hi all,
-
- Lately I've been seeing that the PC is getting more and more powerful. We
- have seen 66Mhz 80486 with the 'Pentium' coming up. Large RAM (upto 64Mb).
- Bigger (upto 1.2 Gb) and faster (downto 14ms) hard disk. Caching disk
- controller with up to 64Mb, 10Mb transfer rate. EISA bus / local bus.
- Fast display adapter with graphic coprocessor. etc. etc.
-
- I'm sure that the technology used in mainframes does not stand still and
- they are also much more powerfull than their predecessors. And I think
- they still deliver much more power than the best the PC has to offer.
-
- But, my question is, what makes the (current) difference in power for the
- mainframes against the PCs? Does their harddisk spin faster? or just
- the data transfer rate is much higher? Or the bus can handle much more
- traffic (wider bandwidth)? Or because they often have more than one CPU?
- Or higher Mhz? Or their RAM is under 20ns? Or any architecture difference
- I'm not aware of?
-
- I'm curious about all this and would appreciate if anybody can enlighten me
- on this.
