Raspberry Pi 3 B+ vs. Desktop

Sun Mar 18, 2018 5:32 pm

How does the new Raspberry Pi 3 B+ compare with desktops?! Is it comparable to a Intel Pentium Duo Core?!

Impossible to answer without a more specific definition.

As a computer doing general office work, Word processing/Spreadsheets/Database/Presentation/Internet browsing, the Pi 3B+ can easily cope*
For programming (ie compiling) a bit sluggish but still quite capable.
Gaming would be where you could be disappointed.

Compatibility would be the major issue, you'd need to find an equivalent open source software package that would meet your needs.

FWIW, I'm just as happy using my Pi's as I am using my laptop.

*Additional storage may be required.

IMHO, it's closer to a Celeron user experience than a Core 2 Duo.

I do

Code: Select all

xz -dc my_russian_raspbian.xz | dd bs=1M | xz -4T4 > /dev/null
(I use dd as stopwatch)
I do it on rPi3b and nettop with Atom 330, with 32bit OS

rPi3b - 1795s
Atom 330 - 1995s

The above is irrelevant, it's about user experience and the various benchmarks or comparisons with other CPU's is like comparing apples with oranges.

I stand by my original post, impossible to answer without more input as to the expectations.

I think that's one of those YMMV questions. It all depends on what your doing with said device.

I personally find the Pi3B far too slow to use as a primary computer. The 3B+ is only slightly faster, and not nearly fast enough to make a difference. I know there are people who use them as their daily drivers, but they must have the patience of Job.

Basic document editing and creation in LibreOffice isn't too bad, and photo editing in GIMP is okay, if the pictures aren't too large. However, web browsing is painfully slow and limited (some web sites won't load correctly, or will just crush the little Pi's performance and drag it to a halt).
My mind is like a browser. 27 tabs are open, 9 aren't responding,
lots of pop-ups...and where is that annoying music coming from?

Very definitely capable.
I have much faster x86 machines of course, but I would be quite happy if all I had was a Pi3B+.
9 seconds to compile a 15,000 line C program with full optimization is good enough for me :)

Try and build the latest Spigot Minecraft server on a Pi, then tell me it's good enough. :(

If the Raspberry Pi is running Raspbian Stretch..

..and your x86 machine is running Debian Stretch and had 2GB Memory then not comparable.

I actually bought a ChromeBrit to compliment my RPi last year, therefore have no x86 machines.

I'd blame the website and/or browser for that. Many sites see the Arm processor and feed the mobile site to the Pi, many browsers however can be set to use the desktop version of the site which in my experience is just as fast as an x86 site.

As I said, without knowing the OP's needs (and your example is quite specific), the question is impossible to answer. Would you run SkyRim on a 486 dx66 with 8 meg of ram?

The Pi3B+ is rated for the same CPU clock speed as a dual Opteron-240 system I built in late 2002....1.4GHz. It has half the memory (1GB vs. 2GB of ECC). I/O speed is limited to 480Mb/s (USB 2.0) vs. SATA-I (15Gb/s), but I can run a Pi3B+ from an SSD (no seek time, no rotational delay) vs. 3 36GB 10Krpm WD Raptor HDDs (probably just about a wash). The VC4 can surely outperform the nVidia 5200 graphics card in the older system, but that GPU has it's own VRAM. Both systems can run 64-bit code, even if the Pi3B+ normally doesn't. The older machine cast $2000 to build. The Pi3B+: $35, plus peripherals. Call it $100 when you include MSD.

So...on the whole, a Pi3B+ is a good match for a 16 year old pretty high powered PC. IF you are running circa 2002 software, and looking at circa 2002 web sites, it would be a pretty fast system. Unfortunately, this is not 2002.

Sure yes, building a large project all in one go like that takes ages (but surprisingly, it is doable, even on a Pi Zero).
But how often do you do that?

When you are developing code, "make" ensures that only the changed files or dependencies get re-built, so its not usually very much (also make will ensure that all four cores get used to do multiple compilations in parallel).

I have had to do serious development work on far far worse machines than the 3B+ over the years.

And the fact that its the size of a credit card, hardly uses any power, and costs $35 seems like a miracle!

Mind you, my cat has taken to sleeping on top of my big x86 tower PC (she likes the warmth) - she cannot do that on a Pi :)

My RPi3B is more akin to a single core Intel Atom, but of course I now have 2GB ram in my Atoms, so they work faster now. :)

I have been using my PI3B as a desktop for 3 months and it is doable but not pleasant.
One has to use Chromium as your browser. It is not possible to watch videos in the browser in HD and there is a limit of 5-6 tabs at one time. Built in audio is terrible as well - a lot of background noise. I do not think the CPU speed is the bottleneck it is certainly the memory - even half a gig would make a huge difference - using a HDD with a SWAP file on it stops annoying system freezes. Overheating is another annoying issue - in 3B+ it may be a thing of the past. Some websites will not work - like OSM editing for example.
I do not play games so I will not comment on that.

I wonder if using zram (basically compression) will help?
Yep, 5 or 6 tabs in the browser is limiting for my usual net habits.

Still it does work as a Desktop, which is great for $35 :D

chromium-browser was compiled for the RPi 2/3 by the RPF.

An alternative is to use kweb:

viewtopic.php?t=40860

Both chromium and kweb have limitations.


The OP has not responded to why he posted and only asked an ambiguous question.......

I normally use Zeros with CLI lite versions of OS.

But with a new 3B+ I've been playing around with the desktop and found it to be more than comfortable for general use.

i have a pitop laptop now upgraded from 3b to 3b+ and for most use it is faster then my expensive i7 laptop and now isnt too far from its specs except graphics processing.

its funny my i7 take 5mins to boot to useable state, where as my pi takes around 30 seconds to boot to useable state

Thats odd, I just did "systemd-analyze" on my x86 i7 PC and a Pi3B+ ..... and they were nearly the same!
The i7 PC (linux) was 14.3 secs and the Pi3B+ was 14.7 secs.

Why does your i7 take 5 minutes ?

Boot time usually depends on the OS, the speed of the main disk, and now with systemd perhaps the number of cores.

my i7 is running windows (booo) so it really slow, ive not tryed it with linux as it has all my software for doing game addonswhich need windows (booo)

it is really cool tho that our little pi's are becoming more compareable to more expensive intel computers

im planning on upgrading my desktop pc to raspbian as soon as the 64bit versin is out
