Speed of the hp calculators family
Where could I find data about comparison of speed of HP41c, 41cv, 41cx, 42s, 28s and other machines (48g, 50g, Prime) ?

RE: Speed of the hp calculators family
Thank you. So the champion is 50g!
I had read somewhere that DM41L is much (a few times) faster than regular 41c. According to this benchmark there is almost no difference. Was I seeing things?

RE: Speed of the hp calculators family
I see that the 50g is assembly while the Prime is formula and list (whatever this means). I think you need to compare aple with aple to make a call cuz I can't believe the Prime is slower than the 50g.
This being said, speed is one thing but knowing your way is more important.

But at least the Prime wins hands down here :) http://www.thimet.de/CalcCollection/Calc...mance.html

I think you need to compare aple with aple to make a call cuz I can't believe the Prime is slower than the 50g. The HP Prime CPU runs at 400 MHz, versus 192 MHz on the assembly benchmark for the 50g. The CPU on the prime could in theory run the exact same assembly code in roughly half the time. But the key word is "could", because in reality it "can't", by being a very closed system. So the benchmark is actually quite accurate: you CAN use the 50g in C or assembly and get that kind of performance to solve NQueens and many other problems. On the Prime you are limited to the interpreted language, which performs as shown on the list. If they only made the Prime a little more open it would certainly take the throne, but "asis" is not the fastest of the bunch. Lots of respect to Xerxes for compiling that list, it's probably the most complete benchmark for calculators you can find on the internet.

I think you need to compare aple with aple to make a call cuz I can't believe the Prime is slower than the 50g. runs the benchmark in 0.336 seconds (HP48GX Assembly / Saturn @ 3.74.0 MHz) at a CPU clock of less than 4MHz , whereas the 50g and Prime need a 192+ MHz modern ARM CPU core to reach a similar speed range;)  Ray

Obviously, the newer 32 bit ARM processor surpasses the venerable Saturn architecture.

I couldn't resist doing the test, and the 50g using newRPL firmware gave the following results: At 12 digit precision: (7.26 seconds for 1000 loops), performance index = 4681 At the default 32digit precision: (12.23 seconds for 1000 loops), performance index = 2786 So it seems the Prime in this benchmark is about 2.6x faster than newRPL on the 50g at the same precision (let's not forget the CPU clock is 2x faster on the Prime). This brings the 50g right below the Prime on that list.

Don't need to bother about being fast...calculators are ladies....see the 15c....and everybody knows that a woman needs more time....

RE: Speed of the hp calculators family
Good point. But today's speeds are a real help. I worked hard to get the HP67 to be able to factor any input value within its integer range (up to 10^10). The worst case, 9999999967, took about 3 3/4 hours as I recall. And its battery pack seldom lasted that long on a charge.
That the WP 34s can do that in a fraction of a second is *very* much an improvement!

Would be a good test for my DM41L. I wonder if it can get power from the USB port...

RE: Speed of the hp calculators family
 0.000192 HP50G HPGCC 3.0 / RegVars / Cross Compiler / Fast Mode x2.5 (75>192 MHz)
  0.000150 HP50G Assembly / ARM9 @ 192 MHz / Fast Mode x2.7 Is the latter of these 2 where you program in arm code directly on the 50g? Phew that must be difficult!
