Dear polite students, no need to theorize about memory
bandwidth and who is "going to be no match in pure performance".

All your bandwidth calculations are
pure bullsh!t, Mr."Tench".

What you need to do is go to
the recent Tom's benchmarks:

www6.tomshardware.com
www6.tomshardware.com

and chart in two official numbers - 284 and 304 - from the
Table 1 of
intel.com
which were obtained on the best of the best -i840
Intel mainboard.

You will find out that despite of 4-fold increase
in every bandwidth as compared to PC100 baseline
(blue line on Tom's chart for regular 440BX board),
the overall performance
of i840 platform on real business productivity
applications has grown by 2.5% only - so much for
all the efforts!

Let me remind you about the benchmark content,
intel.com

"SYSmark 98 includes 32-bit benchmark scripts for the following categories and applications:

Office Productivity:

Corel* CorelDRAW* 8
Microsoft Excel* 97
Dragon Systems* Naturally Speaking* 2.02
Netscape* Communicator* 4.05
Caere* OmniPage Pro* 8.0
Corel Paradox* 8.0
Microsoft PowerPoint* 97
Microsoft Word* 97

Content Creation:

MetaCreations* Bryce* 2
Avid* Elastic Reality* 3.1
Macromedia* Extreme3D * 2
Adobe* Photoshop* 4.0.1
Adobe Premiere* 4.2
Xing Technology* XingMPEG* Encoder* 2.1"

--------- quote ends ----

Please pay attention that all these applications
use intensively UDMA to load/spool data and images
across PCI bus, paint numerous windows and stream
movies across AGP, and, of course, do not forget
to cross the FSB.

From the data presented above it is imperative to
conclude that all your undergraduate ramblings about
traffic streams hold no water what-so-ever. As
it was pointed out here by myself on numerous
occasions.

The REAL system just does not work as you tend to
think. Period. As Steve colorfully formulated,
"who gives a fsck if you can pull 3.2GB/s..."
Go study Hennessey and Patterson at least.

Have fun.
