[gentoo-user] AMD64 on board video

[JimD]

I just put together an amd64 system with the following motherboard:

ASRock 939NF4G-SATA2
http://www.asrock.com/product/product_939NF4G-SATA2.htm

This mobo has an on board NVIDIA GeForce 6100 that uses  shared memory. 
  Here is what the product specs say about the on board video:
- Integrated NV44 graphics DX9.0 VGA
- Pixel Shader 3.0
- Max. shared memory 128MB

The system I replaced had a 64MB Geforce 3 Ti 500 that let me play Doom3 
and other OpenGL games just fine.

I was going to get a PCI-e based Nvidia, however I did not because I 
thought the on board GeForce 6100 would be at *least* as fast as my 
older Gefore 3.  So I spent the money I saved from not buying a video 
card to upgrade to 2GB of dual channel DDR400.

I am still building my gentoo system now, though I have fluxbox and X up 
and running.  I am wondering if I messed something up because I am only 
getting about 1,700 fps on glxgears.  My Gefore 3 Ti 500 would do 3,000+.

glxinfo:

name of display: :0.0
display: :0  screen: 0
direct rendering: Yes
server glx vendor string: NVIDIA Corporation
server glx version string: 1.3

Here is the nvidia stuff I have installed:

eix -c nvidia
media-video/nvidia-glx (1.0.8178): NVIDIA X11 driver and GLX libraries
media-video/nvidia-kernel (1.0.8178-r3): Linux kernel module for the 
NVIDIA X11 driver

Did I leave anything out that is needed for nvidia on an amd64?  Or 
should I not expect anything more from the on board NVIDIA GeForce 6100 
even though it is running over PCI-e?

Thanks,

Jim

Onboard video uses system memory.  So the bandwidth to memory is limited by
PCIe, HT,  and two hops to the memory and back.  Figure memory bandwidth around
800 MB/s to 1 GB/s tops, if nothing else is going on on the bus.

Even an inexpensive 6200 with onboard memory has 4 GB/s or more.  If you need
the performance, get either a 6600 or wait a bit for the newer 7600.

Thanks Bob.  I didn't think there would be that much difference.  The
on-board NVidia is not any faster than the on-board Intel on my new
laptop.  I think the only difference is the NVidia supports DX9 which I
don't care about.

I thought I could save a few bucks... Oh well I guess I will have to
listen to the wife when I tell her I need a video card : )

Come off it, how often does she look inside the box? Pay cash so it
doesn't ppear on the visa statement. Install it when she is out at
whatever_it_is_that_women_do_when_they_go_to_the_movies_together.
Destroy the box.

Well I have been married a little over 5 years.  I "let" my wife manage
the finances starting a few years ago.  She knows how much money is in
the bank down to a dime.  If I tap-mac and get cash, I get the
3rd-degree of what was the money for, especially if I take out $100+ : )

I am afraid I am going to have to go the wuss route and ask the
wifey-poo :)

Well, you could cut back on eating and save, say half your lunch money each
day and stash it.  Or switch to tea from *$ Lattes - Only $1.00 vs $3.50.  It adds
up pretty quick.

Don't do it.  Trust me.  You'll pay big time.  That $100 will turn into $400 to
$1,000 for her, plus a summer of chick flicks.
