What is more important to look for in a laptop? Processor? Ram or RPM Hd?

By LuckyMom ·
I am looking for help in purchasing a laptop computer. I'm comparing these 2 models
Lenova G780-21824mu which has and I-5 processor 6mb ram 500gb Hd and 7200 RPM 17.3" screen for the price of $599 or Lenova G780-21824JU which an I-7 processor 8mb ram 1 TB hard drive with 5400 RPM 17.3" screen for $749. I need my computer for home office only. That is basic programs like word, excel, quickbooks and not for gaming or video. Does the RPM give me a faster performance for my type of work or do I spend the extra $150 for the faster processor with lower rpm? Any advice?

The OS Type is vital in both of these

by OH Smeg Moderator In reply to What is more important to ...

As both have more than 4 Gig's of RAM you need a 64 Bit OS not a 32 Bit OS which can not use more than about 3.25 GIG of RAM.

The extra $150.00 is buying you a Quad Core CPU with Hyper Threading as apposed to a Dual Core with Hyper Threading so the i7 appears to have 8 Cores while the i5 only shows 4 Cores.

The more expensive unit has 30% more RAM then the cheaper one and RAM is the fastest way to improve performance in a computer. It's cheap and makes a massive difference to how fast the unit appears to function.

The cheaper unit probably needs the faster HDD to work at a reasonable speed where as the more expensive one doesn't need the improved HDD Speed to appear that it's working fast enough. It does on the other hand have twice the storage capacity of the cheaper one and with Quickbooks & Outlook this may be important as the Data Files can get very big so extra storage space may be important.

Also depending on how much Data you need to store the extra Capacity may prove useful and the i7 would have a longer expected life as it just has more processing power, memory and storage. While it's more expensive now it will be possible to upgrade the OS for longer than the cheaper one so all else being equal you'll have it longer before you need to think about replacing it.

As for which would be best this all depends on how big the Data Files are, the bigger the Quickbooks Data File the slower it's going to run so the added performance may be useful.

On the other hand if the Data Files are kept to a reasonable size the cheaper unit will have more than enough power for your stated needs and the extra money may very well be wasted as the added performance isn't needed or required.

Though with any NB I always sell a Cool Pad like the one here

remember to remove the space from between amazon and the .com for a working link.

These devices draw little power so they are not a massive drain on the battery and keep the NB cooler and the internal airways clear so the Note Book lasts considerably longer.

I know there can be a LOT of misinformation and misconceptions when it comes to hardware, especially in sales. You can take this with a grain of salt, but I'd correct you on one thing. "...slower processor NEEDS a faster hard drive to work at a reasonable speed..." is incorrect. These days, the hard drive is the bottleneck in ANY system. If you outfit a super-fast machine with a slow hard drive, you often kill any benefits of the faster internals.

With your requirements so low...

I'd suggest surfing garage sales and pawn shops, find something that is between 5 to 10 years old, and buy that.
Then just replace the hard drive (since its probably near death anyways).

Crazy advice, if she has that amount of money available why advise her to buy a ten year old machine? Anything over about 2 to 3 years old will be nearly useless assuming she's going to be using modern software.

Get the best combination of memory and CPU you can afford and try not to install too many dodgy programs. Take good care of it and it should last you two or three years before you need to upgrade or replace it.

That's not true
I got a 12 year old machine running XP and office 2010, runs just fine.

Just cause you got the money, doesn't mean you need to spend it.

G780-21824mu is good enough

by Fasad1 In reply to What is more important to ...

Based on your home use, the first one is good enough and you will save the $250. there will be no real difference in performance for home use.

thanks loads. I think so too. But what I'm wondering is why they make this weird combination, slower processor faster hard drive and the other one has faster processor with larger hard drive, but slower.

The higher density hard drive may not be sensitive enough for a higher speed. Or the version that is sensitive enough would cost too much right now.

With a higher density drive, the reading head has to move quicker and more precisely, it may cost a lot more to make a reading head that can move quick enough to use a 7200 RPM drive.

Tough One...

by info In reply to What is more important to ...

The real question is, "What do you see yourself doing with it in 5 years?" Laptops are so powerful and cheap these days, it's easy to 'overbuy' now (and not a bad idea) not thinking that 4-5 years down the road, they won't be even MORE powerful and cheaper again!

While the 'tech' answer to your question is, "You can't replace the processor in the laptop, but you CAN swap the RAM and Hard Drive, so buy the larger processor..." your 'average' user never will. By the time they would find that $600 i5 laptop to be 'slow', everything has changed so much that they just end up buying a new one. Slayer's comments are not too far off the mark, but requirements change (soon, all 'regular word processing et all will need 64bits, 4GB+ RAM, multi-core, etc... because 'that's just how it is') and you don't want to limit yourself too much. It IS slightly more difficult (expensive) to upgrade a laptop vs. a desktop.
