Laptop CPU question

<< < (2/2)

fohfoh:
I think Lenovo has coverage similar to that. Lenovo has awesome coverage that covers even accidents. Those things are sorta like a brick though, but I sort of like the look.

2.0Ghz might be too low for you. It's just barely enough. No good for multi-tasker fiends like me. (word, internet, music, torrents, chatrooms, IRC, msn etc. simult) But yeah. Both my laptops use T7200s. Decent power, but too much heat. I sometimes wish I spent the extra couple hundred for the P processor... but SZ vs SR Vaio... Carbon Fibre seemed sexier and lighter. :) Not to mention the semi dedicated card.

T3400
T6400
T7200

all run at 2.0GHz. I swear there's an element of overclocking there, which is why it's so damn hot always.

I don't know about the overclocking, but from the specs on Wikipedia (busy at the moment so I didn't bother to verify them against Intel's processor database) they seem to be the "lower-quality" binned processors from Intel's 45nm manufacturing process for Penryn.

Notice that:
1) T-series is labelled as 'standard-voltage', P-series is labelled as 'medium-voltage'. I'm guessing that means the T-series is running at a higher voltage, presumably because it was unstable at lower voltages during Intel's QC testing. Again, I'm busy at the moment so I can't verify this.

2) T-series has a 35W TDP, vs 25W TDP for P-series. This supports the above idea that the T-series is binned for operation at a higher voltage and so produces more heat. I have no idea why their stated operating voltages on Wikipedia are the same, maybe I'll check this up when I am free.

3) In general, the P-series was released later than the T-series. During this period of 6-12 months, Intel probably made some advances in their 45nm process, enabling them to produce a more power-efficient Penryn processor (the P-series).

Long story short, P-series > T-series.



Buying a laptop with a good warranty policy and comprehensive accident coverage is a good idea (unless you buy laptops to disassemble and toy with their innards). Unlike with a desktop, you can't replace most parts when they stop working; upgrades/replacements are mainly limited to the hard disk, memory and CPU (depending on whether it's socketed or soldered). So you will need the manufacturer to do any repairs/replacements, and you can't do that cheaply unless you have said warranty policy and accident coverage.

fohfoh:
Maybe I should have clarified. I mean't there's some type of Bios setup that makes then run faster that is similar to overclocking. (but not really, since it's a manufacturer "standard")

But yes, T use more power than P. That's also a reason why they're hotter. And also yes. Ps are newer than Ts.

Some companies are "bitches" when it comes to upgrades. I know Lenovo allows you to upgrade ram and HDDs without fear of killing your warranty. They even have info on how to do it in the box. (Dunno if it's still the same now). HP voids all warranty if you peek in let alone touch the ram or HDD. Dell might allow touching of Ram or HDD... not sure. Toshiba doesn't really allow for touching of innards IMO. Idk about Asus though, but I think MSi is fine with mods. Authorized Sony repair people don't care about mods. But The actual Sony repair places are very anal.

If I remember correctly dell allows you to swap the HDDs and that is all, otherwise my friend pulled a really lucky one. HP will sometimes tell you to remove the HDD before shipping it to them, past that if you touch the warranty is void. Other then that I don't know much in that area other then Dell and BB have a really good protection plan. Though Dell has a quicker replacement setup for business consumers then personal consumers.

I believe you're allowed ram as well for Dell. Essentially, anything you can touch, you're allowed to mod. But if your mod kills the laptop, it's your fault and warranty doesn't cover it. (ie: if you upgrade to a shitty HDD, the HDD overheats killing your mobo, it's your fault. But if you swap the old one back and claim it was that fault, you can sort of lie your way around it)

I'm pretty sure that there's many things you can touch yourself to a certain extent, because they have an option to send parts to your home and allow you to fix your computer yourself.


HP on the other hand I know you can't really mod anything. They put sealing stickers on everything and if that sticker is "broken", your whole warranty is void.
