I performed the savage benchmark test on my HW-A and HW-D (G2) Prime.
HW_A between 548 and 567 mS
HW_D between 195 and 204 mS
On both machines A = 2500.00005268

See the program below.

Math7,
I have a bad camera, but the exterior is exactly that of HW-C with the improved color scheme!

Code:


EXPORT SAVAGE()
BEGIN
A:=1;
B:=TICKS;
FOR I FROM 1 TO 2499 DO
  A:=TAN(ATAN(EXP(LN(√(A+1)^2))));
END;
B:=TICKS-B;
END;

Note.
I do not want to open the Prime to look at the type numbers of the CPU and memories.
The lion battery is 2000mAh (7.4 Wh) instead of 1500mAh.

My implementation of the Savage benchmark gives a different constant - but it also provides an exact CAS version too, allowing CAS performance to be evaluated too. http://www.hpmuseum.org/forum/thread-9626.html
But I have no hardware to report results on

So I ran your savage benchmark v0.2 from the s/w library (http://www.hpmuseum.org/forum/thread-9626.html) on a brand new (July 2018 f/w) fully charged HP Prime G2 on battery only (not connected to the PC via USB cable). When finished, I connected USB and ran HP connectivity kit to share the terminal output (snipped), attached. I ran it a few times and it comes out more or less the same, but I gave a rough range reflecting the max and min values I observed. Well, I did not have time to do a full stats analysis on this so, I'm giving a very much unscientific range lol . (Someone could perhaps write a program to see what the average and standard deviation is running the benchmark suite 100 times or so.)

Anyway, here are the G2 scores:
PPL1: 0.187_s range +/- 0.05_s
Make: 0.209_s range +/- 0.05_s
CAS1: 2.457_s range +/- 0.2_s
CAS2: 1.831_s range +/- 0.3_s

To complete the picture running the same Savage v0.2 on my G1 rev C (dark blue key board) I get:
PPL1: 0.714_s range +/- 0.1_s
Make: 0.953_s range +/- 0.1_s
CAS1: 9.333_s range +/- 1_s
CAS2: 7.254_s range +/- 0.9_s

In other words with the G2 we get about a 3.5 to 4.5 x speed up (for both CAS and PPL) over G1 rev C.

Since I am using the same f/w from July on both I think the difference simply comes down to faster H/W and I suspect almost all comes from a faster more efficient CPU, but some may also be from a potentially faster RAM - no idea (need to open both to compare h/w and I am not going to do that ).

REALLY NICE upgrade!

Well done HP!
