Will an upgrade from T7300 to T9500 speed up AVC editing?

I've been messing around with mpeg-4 editing (avchd) in sony vegas pro 8 on my dv9500t (t7300, 4gb ram, windows 7 x64 beta) and while it wouldn't be unuseable for editing avchd footage, it's not the quickest editing i've done with the lappy.

I was wondering if upgrading my HP's 2.0ghz t7300 c2d to a 2.6ghz t9500 would make a considerable difference in mpeg-4 encoding/decoding for editing. It's obviously not quad-core with all the modern bells and whistles, but would keep me from building a new, non-mobile desktop...

 

It should help you get a couple of 5 more frames per second.

Actually, its pretty hard to say how much of an increase you'll see, but the higher frequency, more cache and SSE4.1 should help alot in faster encoding, since AVC HD is highly CPU-intensive, 'cause no matter how high the frequency, the CPU will get stressed to >90%.

 

bank on a ~30% improvement as vid editing scales very linearly with clockspeed. If you want 5x the performance get a core i7.

 

yes , i went from t-7300 to x-9000 and things go much faster ! encoding 30-40% faster

 

correct me if i'm wrong, but my lappy can't support the x9000 (not to mention the price difference) due to chipset or power restrictions.

vegas does support sse4.1 thankfully, so that should help if i choose to upgrade...

Of course i7 would be awesome to have but the bulk of my cash is saving for the Panasonic AG-HMC150 which records avc onto sdhc cards

on another note, how substantial are the hp heatsinks?

 

Doubt you will see more than a 10-20% improvement from switching to i7 at the same clockspeed... plus they consume a significantly greater amount of power, too much for any notebook (except Clevo's back breaking monster).

 

You can't get one in a notebook, but you'd see a whole lot more than 10-20%, though less than a factor of 5. The i7s are all quad-core which means a factor of 2 for features things like video enconding which scales almost linearly with the number of cores. The i7s are particularly good at video encoding relative to the Core 2s so there's about an extra 25% clock for clock. Finally, the cheapest i7 is at 2.66GHz compared to his 2.0GHz machine which means a clockspeed increase of 33%. Thus, the overall improvement is roughly a factor of 2*1.25*1.33 ~= 3.33 which is not quite 5, but pretty close.

 

well unless i can jam an i7 into a socket P and make it somehow work, i doubt i'll be seeing that as being an option...

i'm still examining the cost/benefit of the processor, and we'll see where my needs lie closer to when i have the money for my new camera

 

You can't (i7 needs an entirely different motherboard). Upgrading from T7300 to T9500 should speed things up by at least 30%, perhaps a little more because of the extra cache and updated instruction set. It is probably not worth going to to an X9000 because it has a higher TDP and its gain over the T9500 is only 8%.

 

Sorry you're correct, I was thinking about Core 2 Quad to Core i7 desktop counterparts. Same clock speed, I'd still stick with 10-20% depending on application, with video encoding at the high end of it.
