Pentium IV computing power in FLOPS

Hi everybody,
could anybody help me in figuring out what is (even a rough estimate is
OK)
the raw computing power of a 3.0GHz Pentium IV CPU?

really thanks for help

Around 3 Gflops sustained in carefully-coded code with a good cache
miss ratio (for example, dense matrix multiplication in high-quality
BLAS library).

Assuming you’re coding in assembler using SSE* instructions, you can
get a sustained throughput of about 1 FLOP / clock cycle. Since
you’re not really doing that, I’d call the 3GHz P4 about 0.5 to 1.0
GFLOP.

YMMV. Widely :wink:

On the netburst microarchitecture used in the P4 it’s really hard to get
good floating point performance because of the very deep pipeline,
scarcity of registers, and so-so FPU.

That’s great. Please give us a report about the workshop when it’s
over.

Thanks Eric.

very precious info…

I didn’t know of WSR08.
Seems like a very nice conference about Software Radio.

There are three GnuRadio presentations:
Session 6: GNU Radio
14:00 h GNU Radio Based Cognitive Signal Identification and
Classification Platform
W. M. Brown (Metric Systems Corporation, California, USA), J. E.
Clark III
14:25 h Implementation of OFDM Power Allocation Strategy in GNU Radio
Framework
M. Zivkovic (RWTH Aachen University, Germany), C. Liu, R. Mathar
14:50 h Soft-DVB: A Fully-Software Gnuradio-based ETSI DVB-T Modulator
V. Pelegrini (University of Pisa, Italy), G. Bacci, M. Luise

Too bad I heard about it this late, otherwise I would have applied for
doing a GnuRadio presentation too.
(It looks like the submission has been closed since nov 30 2007)

I found info about the conference at:

I checked, and how I found out about was on a post 8/20/07 to this list
from a poster named, ‘[email protected]’ who
posted one notice. Since we had been looking for a forum to make a more
public presentation of what we’ve been
doing, I jumped on it…

I must have missed that one.

Very Good.

I am looking forward for your presentation (and the others of course)

Greetings,
