1975.0. "4d40t vs 4d50t" by NNTPD::"[email protected]" (Richard Quan) Fri May 16 1997 01:04

On a current sales call I was posed the question what do you get extra for the
addtional
6K ($AU) on the 4d50t.  All the tech specs indicate they are very similar in
capabilities additional 
features in terms of performance in some areas.

Where does this performance come from? As memory, etc. appears the same.

1975.1Clock speedPKOPW1::DOTYRuss Doty, Graphics and MultimediaFri May 16 1997 10:347
    The 4D50T has roughly twice the performance of the 4D40T.  The major
    difference between the two cards is the internal clock speed, plus
    different device identification information.  They are identical in
    terms of features and capabilities.
    
    Think of it as the difference between a 333 MHz alpha and a 600 MHz
    Alpha...
1975.2Real-world applications?OSLLAV::JENSHJens Holwech, SBU Workstation Sales Support, Norway (DTN 872-8543)Tue May 20 1997 04:0022
Re .1:

Watch it, Russ! A fairly reputable source (yourself...) recently
verified my own field experience: Very few real-world applications 
show anything but a very minor performance difference between the
4D40T/4D50T (and even the 4D60T). Yes, the CDRS Viewperf numbers
for the 4D50T are almost twice those reported for the 4D40T. 
However, the application used in creating the CDRS test, 
Pro/ENGINEER, does not show this. I also recently ran an informal 
test with a Unigraphics customer: Still not worth the extra cash 
(I'm still waiting to do a side-by-side, timed test, but these 
machines & boards just never stay in the office long enough...).

I'd love to show people the "double performance" of the 4D50T, but
please tell me how to do this! You mentioned Unigraphics as one
application which would benefit from using the 4D50T. I'd like to
know which functions to use in UG to demonstrate this (a macro
file would be very nice!). Also any other application driven 
performance demonstrations would be very welcome!

Regards,
Jens

Hi Jens, here is the results of testing I have done with Unigraphics and
   the Powerstorm boards. This benchmark is mostly graphical. Hope this 
   helps.
