665.0. "summary of alpha implementations?" by RDGENG::WOOD_J ([email protected]) Wed Mar 26 1997 08:49

Does a summary of Alpha implementations exist?

E.g. a table which lists Alpha implementation codenames with
product names and features, such as:


EV4     21064       First revenue Alpha systems. Dual Issue.

EV45    21064A

EV5     21164       Quad issue.

EV56    21164A      Introduces byte & word support.

PCA56   21164PC     As 21164A with addition of multimedia instructions.

(Disclaimer: information above might not be accurate; for illustrative
 purposes only)


Other information such as release date, clock speed range and list of
systems using each implementation would be useful too.

Thanks,
  John

665.3	Yep, Same But Different	XDELTA::HOFFMAN	Steve, OpenVMS Engineering	`Wed Mar 26 1997 09:41`	10
	:>EV5 21164 250-350Mhz Quad issue. :>EV56 21164A 366-622 Mhz Introduces byte & word support. : :I thought we weren't supposed to put the a on there. Correct. Different instructions, different features, overlapping MHz range, same product name. (The customers are beginning to notice and ask about this, too -- differentiating these processors in the product documentation is basically impossible.)

Yes - this is really the reason behind my question. I.e. as compilers support switches for EV5 and byte/word optimizations, if you don't know if your system is an EV56 with byte/word capability, you could be wasting your efforts...

665.6	Unix knows an ev56, and will tell you if you're root	PERFOM::HENNING		`Wed Mar 26 1997 14:41`	4
	also, if you're running digital unix v4 (and you are root) you can say psrinfo -v
665.7	Root access not needed	PERFOM::HENNING		`Wed Mar 26 1997 21:28`	10
	I sit corrected. Digital Unix V4 will tell you even if you are NOT root: /usr/sbin/psrinfo -v Status of processor 0 as of: 03/26/97 21:24:08 Processor has been on-line since 03/25/97 09:31:30 The alpha EV5.6 (21164A) processor operates at 598 MHz, and has an alpha internal floating point processor.

Lucky you having an EV56 @600 MHz! I get: The alpha EV4 (21064) processor operates at 150 MHz :-( :-(
