Gefore GO 7700 1080p H264

[devinwagner]

I need a new laptop. My girlfriend is using it for MS Word, I am using it for 1080p H264 video for my new Sharp 1080 HTV.

I found an ASUS A8-JR with a Gefore 7900 Go and a T7200 2.0 CPU. Can this combo do 1080p H.264 without dropped frames?

Thanks,

Devom

I actually think pretty reliably. I just don't know 100% that the 7 series Go edition does have H264, but it SHOULD.

I know the card does support Nvidia Pure Video and that it does do HD H264. The question is at what resolution? Supporting 720p is not much of a burden, but 1080p is very tough. Anyone have this card or know of a review specifically for a nvidia go chip that tries 1080p?

Looking at the AA 1080p review, it looks like it might not be possible, but I thought a recent driver update might have helped?

Thanks

heres your answer

please bare in mind though, that the pure video engines performance is clock based (hence why a weaker card gaming wise can upsurp the more powerful gaming card at video tasks if it is clocked higher) though it apparently does stop responding to clock changes above 400Mhz so if this chip in this laptop is 400+ Mhz in core clock then it should yield similar results as shown in the tests above

the7950GT is on there, so thats got the 7 series video engine, they tested on a 1.86Ghz C2D and they are all 1080p H.264 tests

looks like your looking at anywhere between 50% and 90% cpu time (tho i think that 90 is a peak and not constant) for H.264, and less for VC1 (less than 50%)

so far the GPU you really want is an 8600. but who knows when they will start appearing in laptops.


so i'd say yes...that laptop should handle things for you, though there is chance of dropped frames on really high bitrate movies considering on those tests they were peaking pretty close to 100%

Thanks that does clear things up. The 7700 go is a 400 MHz card so it seems like the video card may be good enough.

On the proc side they used a E6320 which should be about the same at a T7200 give or take.

So this might be just good enough, with ocassional dropped frames on the highest encoded H.264.

I'm also banking that due to the immaturity of the purevideo drivers, nvidia will improve performance over the next while.

Thanks

well that is a point, specially in vista (maybe) but pure video has been around since the 6 series so they've had a good chunk of time to get things right.

im not sure what decoder you need mind, i know you need the nvidia dvd decoder if you want dvd acceleration etc but the rest of it, i havent got a clue.
