OT: Wheeeeee! New PSpice Benchmarks

[Jim Thompson]

I just got my new 2.2GHz AMD Athlon 64 machine up and running
(replacement for the 1.467GHz AMD Athlon that died last week).

Ran the benchmark I posted 3 years ago.

2.175 times faster !!!

Refresh my DRAM. What was the subject line? I don't think I've got a
benchmark.

Refresh my DRAM. What was the subject line? I don't think I've got a
benchmark.

On 8/23/2001 I posted that a benchmark circuit was available for those
who wanted to try it.

You had to request it by E-mail, since I didn't want my design in just
any old hands ;-)

Three years ago, when I first posted the results, my fastest machine
was an 800MHz P3... the new Athlon simulates at 5.28X faster.

Here are the tabulated results.

Computer SIM Time, seconds
=========== =================
P2 266MHz 1800
P2 440MHz 1082
P3 800MHz 510
P3 1000MHz 420
P4 1500MHz 413
ATH 1.2GHz 270/244 depending on motherboard
ATH 1.4GHz 210
ATH 2.2GHz 96.58

One thing is readily apparent... P4s suck at mathematically intensive
tasks... that's why I switched to AMD Athlons three years ago.

1800*266/1500=319.2 so clock cycle for clock cycle Intel has lost ground.

244*1.2/2.2=133.1 AMD seems to be making better use of clock cycles.

I assume these were all with the same OS.

Good point, but the people I know that build gaming systems all go
with AMD. The graphics are math intensive. They all tell me that the
AMDs do the job faster for a civen CPU speed.

I am interested in running it on my Bochs [1] virtual machine that is running
Windows 98 -- to try to discover emulation bugs.

We don't know that "A" is the cause of "B" in this case. 3D graphics
requires fast low accuracy math and a bunch of memory transfers that don't
simply count up. The AMD may do both better.

It may not even be the CPU core its self that is the cause. These chips
have cache memories built in. Most cache designs assume things about the
pattern of reads and writes. If it assumes wrong, the performance
suffers.

When Intel went to the P4 they tossed the dedicated math core, so they

Jim,

But isn't that the benchmark that LTspice ran about 2.5x
faster than PSpice? Could have gotten 2 years and 3
months on Moore's Law just by switching to LTspice.

I like Bochs, mainly because:

1. it's free (open source),
2. runs in lots of platforms/processors (since it emulates a total x86 it can
run on any Windows (98 and above), Mac OS X, Linux, SGI IRIX, AIX... while
VMWare only runs on x86 Windows (NT/2000/XP) /Linux. I have a friend -
Macintosh user - that uses Bochs with Windows to play some games)
3. It has a debugger (not that I need it, but...)


And it's slow, but it's OK to run some old software.
I use Windows (1.0, 3.1, 3.11) and DOS (3.3, 6.22) inside it.
Better than in my old 386, I can say.

When Intel went to the P4 they tossed the dedicated math core, so they
could devote more chip area to the pablum that the general public
wants.

The whole AMD vs. Intel argument isn't really 'interesting' to me,

but one thing about the IntelP4 -- it does tend to underperform
when using the old stack-style instructions for FP math. When using
the SSE/SSE2 instruction set, it performs much better, but with a slight
hit WRT math accuracy. My application includes FIR filtering, some
transforms and some matrix operations.

I have been writing significant amounts of FP code with the SSE
instruction set, and the P4 is very very fast. It is important
to take advantage of the SIMD capabilities (which isn't always possible)
instead of limping along with the 'stack' instructions. (Of course, the
stack instructions can give higher precision or give access to the
microcoded transcendental math at high accuracy.)

When doing DP math when using the stack instructions (which is what
most compilers tend to use) and comparing the SSE2 SIMD instructions,
based upon real code, the P4 can blow itself away (speed wise) in SSE2 mode.
2X performance improvement for vector (or matrix) operations for SSE2
operations isn't unrealistic (but that much isn't guaranteed.)

The SSE2 instructions do their best for multiple (SIMD) operations -- things
like array operations, which are great for DSP, vector and other
operations.

I'd still like to have an SMP FX53 Athlon64, mostly for the potential
for improved performance for sundry things (in 64 bit mode, some operations
appear to be very quick.) Normally,
I prefer dual processor machines, and am disappointed that upgrading
(or side-grading) to AMD64 from Intel would cause me to loose the ability
to simulate SMP multithreading when choosing the highest performing chips.
(My purposes for using SMP isn't always for max performance -- even though
the extra performance can be nice, but it is the ability to check out
code for real SMP machines... So, HTT helps to give me some of what I
want for SMP, even though it doesn't give as much extra performance as
SMP.) I'd happily 'upgrade' from IntelHTT to Athlon64 SMP, but would
loose the choice of the fastest machines for SMP (or SMP simulation.)

I'd hope we're talking a 64b OS and software for the A64.
Otherwise the gains are truly remarkable!

JT says Win2K Pro so its a 2 bit OS

Win2K is the first M$ OS that I've had not a single problem with.
That's one of the reasons why I haven't gone on to XP Pro. The other
reason being that XP is basically spyware.

Plus I hate this "activation" crap that some software vendors are
going to. It amuses me how hastily Intuit (TurboTax) has retreated
from this approach, after the protest level was so high that it made
the front pages of newspapers around here.
