I have two question about this NEC cpu.

I think it is ES
comparing the other NEC chips of photolibrary
there are 3 type of these NEC chips
ESx.x
Rx.x
x.x
the ES here is most likely engineering sample
if they are not engineering sample
they could just use Ex.x or Sx.x
just as i stated in another thread
http://www.cpu-world.com/forum/viewtopic.php?t=7078
if they arent engineering sample there is no reason to use ES in modern chips to make the future customer confused
i think the ES2.6 here are just like my joshua ES Rev2.2.1 and ES Rev 2.1.1
they are engineering samples
regards!

I don't think that they are ES.
I own about 20 NEC VR10000 from different sources.
All have ES2.6 or ES2.7 written on it.
If these are Engineering Samples, then a non ES is much more rare than an ES

i have 30 more RISE MP6 ( 12 type )
and only 4 of them ( 2 type ) are Q version
the other 20+ RISE MP6 are ES chips
the ES here stand for engineering sample which is documented in datasheet of MP6
actually , if one search the usbid , he will find the number of RISE MP6 ES is 2-3 times more than the nonES RISE MP6 |

So the question is: how do you define Engineering Samples
from: www.engineering-sample.com
"Before releasing a new processor to market, all chip-makers build some pre-productions samples, also known as prototypes. Every CPU announced is preceded by early stepping of the final, commercial version. Inside many labs, these prototypes are called "Engineering Sample", which means these CPUs are only intended for tests and validation purposes. They are used internally and sometimes sent to big customers or to the medias for their own tests"
IMHO: when a company sells many thousands of chips for normal production, these chips aren't ES.
Another question: Did anybody have a NEC R10000 chip without ES? In the http://www.cpuphotolibrary.com are also only NEC R10000 with ES

| got 4 ES 2.6 out of an SGI server, so my opinion too is that they arent samples |

i dont think the point here is how we define engineering sample
the point is
bluecloud has a question whether ES on this chip is abbreviation of engineering sample or not.
how people or NEC define engineering sample is not the point.

how about a chip never mature enough to convince the producer and/or the customer?
maybe the NEC R10000 ES is just like the RISE 150 ES or RISE 190 ES
they are never stable and /or worthy enoughto make NEC produce its R version .... |
