how is P7350 vs T9300 ?

hello,

I am looking to buy a new laptop, i was attracted by new toshiba G55 , but i saw it have P7350 which is only 2.0ghz, my actual laptop is 2 years old and it have Core 2 Duo T7200 whihc is 2.0ghz, what the hell is happening ? after 2 year I want to upgrade and we are still stucked on 2.0Ghz ? how is it compare to T9300 ? I read somewhere on the forum that is low end cheap processor.

Is there any benchmar or information please ?

thanks for your help

 

It will be slower than the T9300 but it will be much better on battery life since it uses only 25w compared to 35w of the T9300. It also has less cache.

 

Clock speeds dont mean anything, its the archetechsure inside the CPU, along with other changes that makes it better.

 

I am still not sure if it is the T7350 or the P7350....
check out this linkand this link....

So if it is the T7350 - it will be a standard voltage, most likely 45nm Penryn-3M CPU....with a TDP of 35W..!!

But if it is the P7350 - it will be a medium voltage, most likely 45nm Penryn-3M CPU....with a TDP of 25W..!!

If you are looking for battery life, go for the P7350..!!

But if it is actually the T7350, the difference in battery life will be negligible between the T7350 and the T9300..!!

The T9300, is a 1st gen Penryn, has 6MB cache, so will be faster than the T/P7350 in CPU-intensive tasks - such as Photo-editing, Video/Audio editing and encoding, etc. The overall experience will be the same with both the CPUs....!!

But if you buy a laptop with a T9300, you are most likely to get one with the Santa Rosa chipset, which would limit the upgradibility to the T9500/X9000....
(Don't know about the backward-compatibility of MV)

But if you buy a laptop with the T/P7350, you will get one with the Montevina chipset, which would enable you to upgrade to better 2nd gen Penryn CPUs in the future....

Even wiki says it is a standard voltage CPU..

 

According to the specs, the T7350 is for FCBGA6, which I believe is soldered in and non-upgradable. Couldn't find any official info on the P7350. The speed and battery life difference is hardly noticeable between the T9300, T7350, and P7350 since CPU is mostly idle. I guess you will have to wait for the official release/review of the Toshiba.

 

I wouldn't say that it is soldered....It will most probably have a socket P..!! (Because only Ls and Us have been known to be soldered)
Only wiki states that it is FCBGA6....but I cannot find any reference for it..!!

spec sheet
it lists both P7350 and cell processor, i dont know if is an option of either or if they are labeling the cell processor as P7350

intel does not have any 'core 2 duo' or 'core duo' processor listed with a "P"
http://www.intel.com/products/processor_number/index.htm

looks like they do have a "future" processor with a "P" designation

update

further research shows that the cell (or rather 'SpursEngine', see wiki) is an additional "co-processor" on the board with the main CPU (intel p7350) that will handle video (h.264 / mpeg2) rather than the cpu doing the decoding

 

That is the part that intrest me most, I ll be doing alot of video editing and encoding. But what scare me that if it is only limited to h264 and mpeg2. Is this mean tha if i do encoding in Xvid or x264 it wont use the Cell processor ? and will use the p7350 ? that will limit me again :S . For me it is mostly for video editing, encoding etc.. so I would like to know in detail if their Cell proc will be faster then any CPU of intel and it will use it for all type of encoding and not just limited to 2 fomats

It is becoming really confusiing.

 

x264 is a implementation of the MPEG-4 AVC a.k.a. H.264.

 

IBM released tools for software development for the cell (probably work with the 'spurs engine' also) free here. its only a matter of time till people the cell hardware and start writing code code for it allowing to to do acceleration for several media related features (e.g. encoding / transcoding) but i would bet that most of those would initially come out for linux due to the ease and commonality for people working on open source projects for linux that over for windows.

 

so you advise me to go for this ? even the main intel processor is a little low (2.0ghz) ?

 

It depends on what you want to do with it. What do you want to do with it?

Aha! No you'd want a faster CPU. Think T9300 or P8600.

 

Go for the P/T7350....First, it will have a MV chipset and the CPU itself is a 2nd gen Penryn.... (and most probably it will be a P7350)....You will be open with the option to upgrade to a better 2nd gen Penryn in the future....

CPU-intensive tasks will run fine with it....I am doing video-editing stuff with a celeron and I am fine with it.. The P7350 should just blast through them.....

For an overall good windows experience, get a fast HDD and about 3-4GB ram....

 

It depends a bit on how much and what you do.

But the OP already has a Core 2 Duo T7200 2.0GHz. So I don't consider the P7350 a big enough improvement to justify the costs of a new laptop.

Unless ofcourse the OP is not expecting a huge improvement in video editing/coding performance.

 

yes i already have a 2.0ghz Core 2 Duo, and i want something more powerfull. As the encoding is really very slow on my system, even encoding a DVD in x264 take more then 6 hours. I really dont know how the cell thing will make things better. I bought my laptop 2 years back, after 2 years if i should buy a new laptop with same processor speed, it kinf of let down for me.

My principale use of lapotop is multimedia, I love encoding DVD's and HD videos in x264 and also doing video editing of movies. Toshiba pretend that it will do job 10 time faster. But what is nto sure if any format used will be using their cell proc or need to wait that developer sart working for it.

Also is P7350 is new generation proc then T9xxx serie ? and is it possible to replace the P7350 proc with more powerfull proc ?

 

Yes, The P7350 is a new gen CPU....I can't be sure, but logically it should be as easy swapping the P7350 for a T9600, etc as it was to swap the Santa Rosa CPUs....

 

hmm there isnt any web site where we can confugure toshiba laptops ? so that i can choose btter processor from beginging. I really need to buy a upgraded laptop, as i have so many DVD to encode to make a juke box before i go for travelling. and there isnt any review of this laptop, seem not so popular and toshiba is so bad for Advertisement

 

I am interested as well in *maybe* buying this Toshiba Qosmio G55 Laptop, I just have a few questions, can this CPU be upgraded to future Quadcore Centrino ? And I'd like to buy this at a Canadian Retailer and so far all I have been told by Toshiba Canada is it will not be available in Canada. Any other alternative or maybe how to buy the Qosmio G55 in Canada?

 

Threoretically, yes you should be able to upgrade to the quad-core....!! It is in fact hard to say, since it hasn't been really released yet, and I am unaware of the fact if it requires some special BIOS or stuff like that..!!
You should be able to goto the X9100 (esp if you are buying a >15" notebook)
If you do not want to wait till the release of the quad-cores, I would advise you to go for the notebooks with the higher-end chipsets (GM45, 47; PM45)....keeping upgradation in mind..

 

They'll probably have a different socket, and heat requirements(and power requirements).
It wouldn't really be worth it.

 

but the P8600 or P9500 could be installed ? if yes is it easy to install a CPU On noteook ? and doese this void the Warranty ?

 

Yes, (maybe not on the GL40)....

Easy - varies from one notebook to another....some may have to be totally stripped to reach the cpu and heatsink, whereas others have their heatsink and cpu, by removing the rear panel..!!

Not sure about voiding warranty, but if the cpu upgrade spoils or damages any other part of the notebook, or any damage is caused due to the upgraded cpu, there will be no warranty cover for that damaged part..!!
And you should keep your old CPU with you, so that when you send your notebook back to the manufacturer under warranty, you can replace that old OEM CPU..!!

 

ok Thanks angad for the information now i have to decide what to get. I have to go to other forum to ask that

 

I would advise you to go for the notebooks with the higher-end chipsets (GM45, 47; PM45)....keeping upgradation in mind

What are the GM 45 and so forth? I'm a little in the dark interms of some laptop tech lingo.... would this laptop be able to upgrade to a quad core? I know you answered already but if you could explain I have to see if somehow some way I could get it here in Canada, otherwise I'm going to look at <sigh> Dell.

 

how to know what chip it is ? i dont see that information indicated on specs ?

 

Ask the dealer, manufacturer, or look for a datasheet for that model or some detailed documentation....!!

 

OK now here is the deal, i am seriously thinking of taking Qosmio G50, i already open an other topic so that people can advise.

If ever i have choose the G50. I have choice between

P8400 or T9400 , the chipset on both is : Intel® PM45 Express chipset

Now there is a huge difference of price, the model with T9400 is 400 euros (300 pounds) more expensive that is crazy , as when i see the price of T9400 bow version, it is less then 300 euros.

So i can go for p8400 and save money ? and if i need more power i can get P9500 which is less then 300 euros later ? will P9500 mount on the chipser : Intel® PM45 Express chipset ? Also the cpu are not solded on motherboard ? on qosmio how to knwo if it is easy to change the processor ?

Thanks for your help

 

The P8400 is plenty of power. You won't notice a difference with anything higher.

 

What about the P7350 ? Is that not plenty of power?

 

P9500 should work, T and P CPUs are not soldered to the motherboard (Socket P) and look for a service manual or repair guide for your notebook on the net.

P7350 is fine for everyday tasks and decent gaming....

 

Thanks alot i ll go for P8400 and save 400 euros lolzz

 

Why hasn't anyone made mention of the Front Side Bus for both of these chips.

I say go for the P7350 -- It has a 1066MHz front side bus speed.

Compared to the T9300's Front side Bus: 800 Mhz.

Yes even though the T9300 has a faster CPU and a bigger cache.... with the P7350 you will get better use out of the 4 Gigs of Ram... in other words u will get more bang for your buck.

In the end both will function at similar perceived efficiency. So go for whats cheaper... that and well the Toshiba is already 64bit ready (Toshiba is including a 64 bit OS... which again makes proper use of all 4 Gigs of RAM).

MY CHOICE: P7350

 

No offense, but I dont think the OP waited ~2 months to decide which one to go with. But hey, you never know, maybe he was waiting for you to come along and tell him whats what

 

The P7350 has indeed 2.0ghz but it has a FSB of 1066 whilst your older laptop probably has a CPU with a FSB of 800, so there IS an upgrade...

Yes indeed, that's a very good choice!
