I got a score of 18 on a dual core
Pentium D 945
Improvements for netburst going to Firefox 32-bit were less than I expected, but it did help a little. I got a score of 19.1 after installing 32-bit BSD unix and retesting firefox on 32-bit.
I got further improvements (surprisingly slight ones, +0.2) by choosing 2-thread processes over the default 8 thread.
Pentium D 945 gets a final score of
19.3
Other devices+browsers I've tested:
6 --- Kindle Fire (5gen, quadcore)+Chrome
61.2 --- FX-8350** + Brave
77.3 --- FX-8350** + Edge
** I have turbo boost disabled on my FX system as I want to maximize remaining lifetime of this 760g board. (This system runs at full load all the time during heating season, thanks to BOINC, and 760g's really stress the limited set of mosfets in the VRM of such low end boards); because of its good L3, my FX also gets bottom of barrel DDR3 1333 with slow CAS timing)
I think my 2500u laptop scores somewhat below my FX's Brave score, when tested with Firefox, @
47 .
47 using Firefox ESR (78) on my linix laptop (2500u @ 15w)
I just retested today with recent release of google chrome, and it is dramatically faster than Firfox ESR on the 2500u at a whopping
108 !! (indeed, I think even very different version numbers of chrome will produce different numbers, and even setting like whether you enable hardware acceleration):
It's really incredible how optimized Chrome is. One could probably put together a nice
64-bit chrome browsing station with an old Phenom tri or quadcore, or even a bottom end station with a dual core K10 era Athlon (maybe even
k8 dual core?).
I'm guessing 32-bit Chrome is no longer supported/updated. For anyone running a 32-bit CPU like C2D (including abandoned macbook users) I highly recommend
32-bit BSD unix + Firefox, which are noble holdouts for 32-bit support. Even though Firefox is not as optimized, it's still plenty responsive for cores like C2D, and even Pentium D for most webpages and not too many open tabs.
