PCI video card upgrade for P4 HTPC

[JD]

Well you see any 8400GS has CUDA support and since CoreAVC now uses CUDA, that means the GPU can do a very large chuck of the decoding regardless of the actual HD-decoders within the GPU.

And the only ATI GPU thats PCI (that I can find at least) is the 2400 Pro which I don't think is really any better.

no matter what you stick in there, you're going to be limited by the 133mb/s limitations of the PCI bus :(

Wow, I logged in at 3am, just to thank you for that tip, I received 8400GS today (G98), purchased CoreAVC and run H.264 video test, the CUDA kicked in and CPU usage dropped from 100% to 40-50%!

Look, all it takes, a 6 years old PC, $60 PCI card, $20 codecs and I have a monster machine that can decode high resolution video without breaking a sweat, probably for the next 5 years. A miracle.

With fanless card the noise from PC is almost non existent.

Glad to hear it worked out as planned

artistpavel yo, i was wondering were you playing 1080P on that P4 with the 8400gs?

i got a 2400pro and i can't seem to get it to work :S

might be due to the PCI slot.

when i had a x1650pro AGP it decoded 720 with extra room. 60%-85%

P4 specs
2.6ghz

Needs to be a NVIDIA card that supports CUDA so that you can run CoreAVC w/ CUDA enabled. Then you should be more than able to play 1080p content.

Looks like I showed up a bit late. I actually found that the Combined Community Codecs used less resources than CoreAVC. Combined Community Codec Pack

May be worth making a comparison

CoreAVC + Nvidia CUDA made me run 720 content with 40-50% of Pentium4 2.8 Ghz utilization, I didn't have 1080p movies to try, but it looks like there's enough room for it.

I'm currently building new e5200, HTPC, this time however I'm using PCE-E version of 8400GS. CoreAVC + CUDA combination dosn't work on 64 bit system for me though.

Hardware acceleration doesn't really matter for me now, since I'll be using XBMC for movies and it doesn't support GPU offloading, I paid for 2 cores and I want them to flex the muscle.

the CCCP now uses MPC-HC, they have a lot of fixes compared to the no longer updated MPC.

But for H.264 files using CoreAVC + cude is so much simpler

Thanks for your input

i had a 8400gs PCI a few months back but i refuse to purchase the coreavc. But after seeing your results on your g98 i picked up a 9400gt PCI + coreavc to test if it can play 1080P h.264. Crossing my fingers

I only have Final fantasy advant children for 1080p

will post results when soon
