let's say if there are 2 CPU, one is quad core 2.5ghz, the another is dual core 3.0ghz. the dual core 3.0ghz support hyper-threading , while the first one doesnt . Which CPU will perform better?

Most laptop come with 2 ram slot.. mostly support up to 16gb (2x8gb dual channel)

Seldom laptop support 32gb or abv, if it support, it can be 2x16 or 4x8 (16gb single ram is very exp as it's mostly for server / workstation)

It's preferable to have 2x8gb dual channel than a single 16gb single channel ram as dual channel is faster..

Also note that there is no need for you to go to so extreme as in 16gb or 32gb ram.. 2.6k laptop with so much ram won't do much good as you got a slow processor..

And also note that if you want to upgrade the ram yourself, make sure you read the T&C as most big brand will void your warranty once the backlid / back cover is unscrewed and removed.

Both quad core and dual core support multi-threading.. if not whats the use of multi core
Eg: dual core 3.0ghz will do better in gaming as most game program just use 1 core to run it..

I think 2 slot is enough already. People always go with 2x 4gb ram or 2x 8gb ram. More than that, you may need a desktop. Dunno whether 32gb is possible or not.

~some previous hp and dell (inspiron 3000 series) have 1 slot only. So better add ram on the spot while buying.

i am using 5 year-old q8300 quad core processor desktop. I checked it on the website, it doesnt support hyperthreading.

Yup. I mention it. i3/i5/i7 only. And xeon

As ashraf095 mentioned.. we're talking about intel i series.. so it does support hyper threading.. (Except you wanna compare to those very old processor which most laptop won't use in this era )
For others then probably no..

for this time 1 slot only can support 8gb. so u need powerful lptop to upgrade
why not try aftershock laptop

32gb posible now bcoz i see certain lptop suport it like gigabyte and alienware
but this lptop very expensive

Yup.. 32gb is possible with laptop.. Just very exp..
And no point getting so big ram for laptop, not like you gonna do AI training data stuff in a laptop.. mind as well go for a workstation/desktop

Just remember getting a better cpu rather than more ram.. High ram capacity w/ slow processor, your laptop performance still is slow

I am thinking of getting this laptop too. But I am a bit worry about the after sales service of HP. Anyone know, is it reliable? I hope it is not like Asus As this is my first time thinking of purchasing HP i am worry bout the product too
Mostly, I will be using this laptop to listen to music, stream movie and assignments (word, power point). Video and photo editing will be a plus too. I have a budget of exactly 2k. I hope this is worth it?
So does the speed of AMD Quad-Core A8-5545M APU with Radeon HD 8510G Graphics (1.7 GHz, 4 MB cache) almost on par with i-5? Sorry, I am a newbie here. Just started reading on laptop yesterday.

For HP I think the after sale is okay according from my personal experience.. not so good not so bad..

Last time I sent my HP dm4 Pavilion to claim warranty for 2 times
First time is wifi card problem and 2nd time is screen issue.. both take about 1 week or so..

It may be very long.. but at least they didn't complaint much or pusing pusing.. str8 away provide me a replacement..

If you really afraid of after sale issue, get Dell.. confirm no problem.. Dell is well known for their after sale service.. RM2k I think can get a decent laptop with i5..

I bought my HP dm4 pavilion with exactly 2k w/ i5 and 4gb ram..

P/s: 2k budget laptop maybe be able to do light video editing, but intense 1 sure can't

Thank you for the advice and recommendation! I will definitely check on it later.

is there any heat problem so far with your hp laptop?

It's dead now.. haha
It's a 4 years old laptop.. no more warranty.. and I dropped it this year.. the screen cover lid got a crack and my screen is now all pink colour.. the wire got damaged.. since warranty is over i just get a new laptop (illegear z5)

The laptop is pretty decent, but no gaming.. cuz the performance is not that good.. noob gc.. The machine also feel hot even under normal load because i didn't clean the fan dust and repaste the thermal paste for 4 years.. lol
(4 years didn't maintain my laptop)

It's a pretty ok laptop as I didn't do any maintenance for the pass 4 years

Where i can find that laptop. Tried searchking at harvey normans but no avail
