deciding on a new amd64 system

2007-05-22 Thread Alexandru Cardaniuc
Hi All!

I've been using HP Pavilion zv5260 as a desktop replacement for a while
and now decided to get a real desktop. I am not sure if I should build a
new box myself or buy a pre-built one. I need a home workstation that is
going to be used primarily for writing and debugging code, browsing
internet, occasionally watching dvds. I don't edit video and don't play
video games. So, I figured that I don't need that powerful and expensive
computer. In this case does it make sense to build one myself?

I googled and found that Dell offers Dimension n Series E521.
http://www.dell.com/content/topics/segtopic.aspx/e510_nseries?c=uscs=19l=ens=dhs~ck=mn

It comes with no Windows OS preinstalled. And Dell claims that it is
ready to work under linux. 

Does anybody here have this machine? Are there any compatibility issues?
I plan to use it with Debian Etch. Etch comes with linux kernel 2.6.18

Googling I found out about a problem with USB freezing mice and
keyboards, but it seems that this problem was solved with BIOS update
that Dell issued in January, 2007. Google doesn't show any more problems
with it...


I am thinking about choosing these parts:
-
Dell Dimension E521NAMD Athlon 64 X2 Dual-Core 4000+

Operating System: FreeDOS included in the box, ready to install

Memory  1GB Dual Channel DDR2 SDRAM at 667MHz- 2DIMMs

It seems like the price is right. Before I always built computers
myself, but now would I actually be able to build a box myself for this
price ? Well, I don't necessarily want cheap, I just don't need a very
powerful machine for what I am using it...



Any advices or suggestions will be very appreciated!

Thanks in advance...

I use to buy the components and assemble what I need.
There is guidance on internet, just choose a reliable
guidance. If you go through a reliable European
internet dealer you can save money and have just what
you need (and the latest - albeit latest on European
standard - components, which is never sure on buying a
commercial box).

Personally at this time I would buy a Core 2 Duo instead.  Faster and

Oh and it's a Dell, so the pwoer supply and mainboard and possibly other
things are probably proprietary and never replaceable.  And the power
supply is probably only barely large enough to handle the system, so
upgrades could be tricky.  At least that is how Dell Dimension PCs were
in the past.

 Operating System: FreeDOS included in the box, ready to install
 
 Memory1GB Dual Channel DDR2 SDRAM at 667MHz- 2DIMMs

Why does Dell (and other rip of the clueless consumer name brands)
insist on putting slow ram in machines with fast CPUs?  800MHz ram
doesn't cost that much more.  I guess they figure their customers only
care about price.

 Dell USB Keyboard and Dell Optical USB Mouse

 powerful machine for what I am using it...

The difficult part in getting a price like Dells is that most people
building a computer aren't willing to cut the corners Dell likes to cut.

Let us try though:

Athlon 64 X2 4000 $122
2 x 512MB DDR2-6400 800MHz OCZ platinum ram $80
Asus M2V mainboard (10/100/1000 ethernet, 5.1 audio) $90
WD 250GB SATA $79
LG 18x DVD+-RW $38
Antec SLK1650 (case with 350W PS) $70
USB mouse/keyboard $30
7300 video card $63
19 LCD screen $200

Total: $772 (canadian) which is about $730 US.

Significantly higher quality components than the Dell, but you would
have to buy and assemble parts yourself, and you don't get tech support
and warrenty (well warrenty on the parts not the system).

But overall, Dells price is just OK, not great.  Remember the Dell is
full of cheap junk which helps them keep the price down.

Modem (if you actually need one) which is actually a hardware modem that
works with linux is probably $75 or so.  Haven't bought one in years.  I
tend to assume most people don't need it so I will ignore it.  I would
be surprised if dell included anything other than a winmodem in their
system.

Personally I would go with spending more on a Core 2 Duo if I was buying
one, but I am not at the moment. :)  And I would get a 7600GT rather
than a 7300, and I would go for a silverstone TJ04-B case and probably a
silverstone 450W power supply.  And I wouldn't go for less than a 20
screen since I hate 1280x1024 screens, while 20 gives you 1600x1200.
Of course those changes would probably add another $500 to the price.

I just had a box built at CompUSA. It took me a while to get it up, but 
it's happily running Linux now. I looked at the Dell Linux-ready 
systems but ended up with a custom system mostly because


1. I didn't want to wait.
2. The Dell AMD systems didn't include the option to remove the monitor. 
The Intel systems did, but I wanted AMD.

3. The Dell memory prices were too high.

So I ended up with a 4 GB Athlon64 X2 4200+

If you already have a monitor, you could get the low-end Dell Intel 
Linux-ready system without one and save about $150US, IIRC.

Well I would certainly prefer 2 or 4GB ram on a new system.

As for AMD, well when they come out with the quad, assuming it does what

Lots of boards have 7.1 audio, I just tried to show that making a PC
from quality parts that matched the Dell price was trivial.  I was

I think I must have gone to sleep for a couple of years. When I was last

much better than Intel's, because (I think this is right) for 
communication between cores, the AMD doesn't have to go off-chip, but 
Intel's architecture requires use of the external bus, and AMD's design 
just plain scaled better. Or something. Then fast forward to today, 
where apparently Intel's Core 2 Duo is apparently kicking the pants off 
AMD... how did this happen? Is Intel really all that much better?


Also, I only really hear comparisons between the Core 2 Duo and Athlon. 
How about Opteron? Is the Opteron still a good choice for servers? Or 
has Xeon leapt ahead there too?


Sorry for the ignorance. I don't pay much attention to hardware stuff in

With the pricing on DDR2 ram now a days it is an easy decision to go with 2gb 
I got my 2gb for a little over $140 CAD just over a month ago and can get the 
same ram today for just under $120 CAD plus the caching does not hurt either 
just speeds up the machine even more. I am almost tempted to get another 2gb 
to throw in just for the hell of it.

Intel just did not stand still when getting their ass kicked they went out and 
designed something better. The Core 2 Duo is definitely faster when I built 
my new machine I just moved the hard drive from my old system AMD X2 939 
running at 2.4ghz 2gb ram to new Core 2 Duo 2.49ghz 2gb ram. I re-complied 
the kernel on old for the modules needed to boot the new system it took just 
like it always did about 12 minutes on new machine it takes just about 8 and 
a half minutes. Now even with the new being ~100mhz faster and the ram 
running at 356FSB (DDR712) 5-5-5-15 vs old 240FSB (DDR480) 3-3-3-7 I don't 
think that can account for about a 3 and a half minute difference.

 Also, I only really hear comparisons between the Core 2 Duo and Athlon.
 How about Opteron? Is the Opteron still a good choice for servers? Or
 has Xeon leapt ahead there too?

From my experience of having had two different Opterons in my 939 board both 
of which I ran as fast as my X2 there was next to no difference in the 
performance of them vs X2. So Opteron vs Core 2 the Core 2 is faster against 
the Xeon I have no clue never had one of them.

 Sorry for the ignorance. I don't pay much attention to hardware stuff in
 between computer purchases. Last time I really looked was in 2005 or so.

Ram is cheap, firefox leaks memory (or wastes it) like crazy.  KDE
doesn't seem much better.  Until people start taking code quality
seriously, it is simpler to throw more ram at it.

 where apparently Intel's Core 2 Duo is apparently kicking the pants off 
 AMD... how did this happen? Is Intel really all that much better?

The Core 2 Duo has an internal connection between the two cores (they
are a single die) just as the Athlon 64 X2 does.  The Core 2 Quad has
two Core 2 Duo dies attached together using the front side bus.  So for
a quad design, the Core 2 is similar to the dual core design intel did
with the Pentium 4 (aka Pentium D).  The Core 2 is based on the
Pentium-M core which goes back to the PPro (it is derived from the P6
core).  The pipeline is in the low to mid teens, unlike the netburst
which managed to go past 30 stages (great for clock frequency, bad for
dealing with conditional branches).  So in terms of design, the Core 2
has a lot more similarity with the Athlon than the Pentium 4, except it
is a bit more modern and has some clever tricks, which makes it able to
run faster than the Athlon 64 at the same clock speed.  Hopefully those
improvements AMD is promising in the next version of the Athlon 64 will
in fact give them the same or hopefully better performance per clock
than the Core 2 Duo.

 Also, I only really hear comparisons between the Core 2 Duo and Athlon. 
 How about Opteron? Is the Opteron still a good choice for servers? Or 
 has Xeon leapt ahead there too?

The Opteron is an Athlon 64, except it (usually) uses registered memory
(allows more banks of memory in the server, at a slight speed penalty).
Current Xeon's are Core 2 Duo or Core 2 Quads, with a different bus
speed (I believe they tend to run 1333MHz effective bus rather than the
1066MHz of the Core 2 desktop chips).  Xeon's also usually have more
cache.  Of course the opteron has the fast hypertransport link between
cpus, and per cpu memory controllers, so the memory bandwidth is better
on the opteron with lower latency, which is why the opteron still scales
better than the xeon.  For single or dual cpu the xeon is usually
fastest, but for 4 or more cpus the opteron is better off since the xeon
still has to share a single bus to the chipset for all the cpus while
the opteron has the hypertransport links between cpus instead for memory
accesses and only has to use the link to the chipset for accessing
devices.  Adding opterons and memory gives more overall memory
bandwidth.  Adding cpus to a xeon system doesn't add bandwidth, just
processing power.  Until intel some day gets an on chip memory
controller.

 Sorry for the ignorance. I don't pay much attention to hardware stuff in 
 between computer purchases. Last time I really looked was in 2005 or so.

Lots has happened.  It is nice to have some competition between AMD and
intel to keep them both going, although I like to root for AMD being the
underdog.

  I've looked for it and I can't find it.  This is what I'm using as my
  apt source.list:
 
  deb http://ftp.debian.org/debian/ unstable main non-free contrib
  deb-src http://ftp.debian.org/debian/ unstable main non-free contrib
 
  deb http://debian-multimedia.dfoell.org unstable main
  deb-src http://debian-multimedia.dfoell.org unstable main
 
  Thanks.
 
 You download the plugin from the Adobe website extract the tarball then copy 
 the files (.so and .xpt) to the /usr/lib/plugins/mozilla directory then run 
 the nspluginwrapper -i /usr/lib/mozilla/plugins/libflashplayer.so command to 
 install it. The file I used was install_flash_player_9_linux.tar.gz putting 
 this into Google should come up with it.

Something I was struck by while looking at Googled sites... do I need to
have a 32 bit Iceweasel for this to work?  Or will it function under the
regular one?  (Or am I off my rocker thinking that this is a 64 bit
app? ;-)

No it works with the 64bit apps with the wrapper running the plugin I would 
think translating the 64 to 32 bits to communicate with the plugin then back 
again I am really no expert on it but that is the only way I can see it 
working.
