Really? Always?

You mean just plain weaker or that they're underclocked?

Yep, for similar models always, they might either be underclocked, have less cache memory on chip and other measures that reduce power consumption and performance. Don't be surprised, for example did you ever expect a current smartphone to be as strong as a current pc? Same goes for laptops, they are weaker, only not that much.

Man, that's BS. You might as well just underclock it and let a user overclock it to desktop speeds if he/she wants.

That's not BS really, if you do you will probably fry the chip, laptops have a very small space and limited cooling options. It is done due to practical issues. Of course companies take advantage of that fact to make some more profit i suppose .

Nothing a cheap $20 fan can fix XD

But honestly, I guess I'll have to deal. I really need the portability so I'll have to put up with some slightly lower performance. Dolphin appears to be incredibly intensive--for comparison, the crappy computer I have now can run some games in PCXS2 with surprisingly high speed (30+ FPS) while Dolphin makes it curl up and die horribly.

For 一ne thing laptop CPUs don't actually have the same model number as the desktop CPUs, so they are in fact different models. Core i5, AMD A8 or whatnot are just product brands rather than individual CPU parts.

Here's an analogy:

Intel ~ Apple
Core i5 ~ Iphone
2500k ~ 4S

Of course, unlike other CPU product line-ups Core i5s are particularly different between laptops and desktop. On laptops they're 2core/4thread CPUs but on desktop they're 4core/4thread CPUs. With pretty much all other CPU product brands they are at least the same underlying CPU, just with a different clockrate and/or cache amount.

Yeah.....no.

You would need a large heatsink, a large vent, and multiple high rpm fans to get the equivalent cooling of a desktop. And you cannot fit that inside a laptop chassis, it's impossible.

For the most part desktops and laptops these days use the exact same chips. But the laptop versions run at lower voltages and clock rates to improve battery life and reduce thermal emissions. Even if you could provide enough cooling to run the chips at the same speed as their desktop counterparts who would want to use a laptop with a 30 minute battery life that quickly reaches near boiling temperatures when on?

Unlocking every laptop and letting the users decide would be a stupid idea. Most users have no clue what they're doing. They don't understand the first thing about electronics or electrical engineering. Doing this would cause these companies to be swamped with people returning/repairing laptops that were destroyed by overclocking. They would not be able to provide a reliable product or enforce the warranty. It would be chaos. Users would end up doing extensive testing to determine the highest settings they could use without overheating the machine. Which is essentially what cpu manufacturers already do when they test their chips. Leaving a bit of headroom in case of dust buildup (if they're smart). We have testing and certification with hardware for a reason. This defeats that reason.

I like NaturalViolence completely skipped over the part where laptop and desktop CPUs have different model numbers. I guess I shouldn't have expected any less from him.

[NaturalViolence]

?

Which part of what I said do you dispute?

They have different model numbers but they use the exact same chips. In most cases the only differences are the packaging and the settings.

Edit:
Take sandy bridge for example. There are three chips in the sandy bridge family:
Sandy Bridge-HE-4 (stepping D2)
Sandy Bridge-H-2 (stepping J1)
Sandy Bridge-M-2 (stepping Q0)

All three of these chips are used for both laptop and desktop sandy bridge cpus.

I'm sorry. We really do get people that dumb on a regular basis here. It's hard to tell who's being sarcastic and who isn't.
