Question

Is the processor used for Laptop and Desktop are same. I havs seen 2.8 / 3 GHZ in Desktop but not in evel latest Laptop? are they same or different? What about the AMD processor based laptop. Which is best. Heard AMD generates high amt of heat. Is that reliable processer? thanks in advance

Answer 1

The basic answer to your question is no. Laptop CPU's are designed to run only as fast as they need to run to get the job done, while desktop CPU's run at maximum speed all the time. The whole Idea is that the laptops want to conserve battery power and generate as little heat as possible, since they only have small fans. Desktop hard drives normally run at 7200 rpm while laptop hard drives normally run at 5400 rpm. Again the reason is that the faster desktop hard drives give off more heat than a laptop can deal with. This makes desktops do things like reboot, start new applications, and load files much quicker.

I have an AMD 64 2Ghz Gateway Laptop and it works almost as good as my 2.4 Ghz Desktop; but I understand the new Intel Core 2 Duo currently performs the best. I'm sure AMD will catch up next month and the month after Intel will come out with another new one which runs better and costs more. In my opinion, today you'll get much better value for money if you buy the one that was last month's best.

Good Luck!

Answer 2

the answer is tricky.. sometimes you can use a laptop or "mobile" processor in a desk top but a lot of things have to work out. You must have the proper voltage, the proper slot/socket, bus speed and such. A few years back overclockers found some pentium mobile chips were great in desktops as the voltage regulator was unlocked and with certain motherboards they could get incredible speeds out of the chips where the comparable desktop chip was voltage and multiplier locked.. So yes and no ..it's a crap shoot at best. There’s actually a fairly long-running tradition of people using laptop processors in desktop PCs. In the early Socket 478 Pentium 4 days, overclockers loved the P4-Ms that ruled the laptop roost, because they had plenty of headroom and fit into standard desktop motherboard sockets. Later, when the cheaper Mobile P4 came out, the Celeron versions of those chips were especially good overclockers — the 1.6 GHz version could hit 3.2 GHz using standard cooling and desktop-PC voltages, and 2.66 GHz using the normal laptop voltages. Overclockers used mobile processors on the AMD side, too – the Athlon XP-M was notoriously good at attaining high speeds, and probably the mobile processor used the most of any other mobile processor on desktop systems. Nowadays, they use Turions and Mobile Athlon 64s in Socket 754 motherboards.

Answer 3

Laptops processors and usually different then desktop ones. The Pentium M (Centrino) is only used on laptops, has a lower clock speed, but will out perform desktop processors of the same speed and higher. Now, there are some desktop processors that do find their way into laptops (namely celeron and Pentium 4's) but I would not purchase a laptop with a desktop processor because of problems inherent to them, runs hotter (especially the P4), uses to much power (which leads to shorter battery life). You heard wrong about AMD, their processors are not blast furnaces (like the P4 is). AMD is a leader in processor technology, first 64 bit proc, first dual core for servers and desktop, they have an 8 core processor due out this way, and their processors are very reliable, more so then Intel. AMD never has had to recall any of their processors, Intel has.

Answer 4

the desktop GHZ is higher than the one of Laptop..
they are not the same...also in memory..laptop usually comes in much less....desktop has more memory.

talking about processor...i strongly advise u not to get AMD...it consumes more battery power..u should buy the latest Core Duo 2 processor..or if u cannot afford then u should go for Core Duo..
don't go for celeron...it is old...

anymore additional question...u can e-mail me at [e-mail]

i will be glad to give u some more information about the processors..i have handled this processor things just few months back..
feel free to ask......
bye

Answer 5

A previous poster mentioned heat, and that's part of it. The main reason is power consumption (which creates heat), and the resulting loss of battery power. People want laptops that will run for a fair amount of time, and with hungry processors you'll need to increase the battery capacity (which costs more and adds weight).

Increasing the speed of a processor typically increases the power consumption. (When you transition a signal from low to high, or high to low, it takes a certain amount of energy. The faster the clock is, the more you are doing this in a given period of time, and this results in more energy being used)

Faster processors generate more heat. Faster processors use more energy. It's somewhat of a trade-off between performance and battery life.

Answer 6

Desktops can generally support a lot faster processor than laptops, one major reason being heat.
The current AMD processors generate a very reasonable amount of heat unlike olden days and are as good / better than their Intel counterparts.
The Intel core2Duo is however the best in the market primarily because it consumes 40% less heat that any other processor in the market.

Answer 7

Try trolling acer laptops I hear they have desktop processor in them from someone who specalizes in selling laptops over the internet.
