Intel® Core™ i5-520M
#1
I'm asking this question on behalf of my bro

the Intel® Core™ i5-520M processor, is this a 2.4ghz processor in duo mode and a 2.93 GHz in single mode?

Intel
Windows 7 - Asus G73jh-a1 - 17-720qm @ 1.6 GHz (2.8 GHz)(2.4ghz)(1.73ghz) - ATI Mobility Radeon HD 5870 @ 700/1000 (sometimes oc to 800/1100) - 8 gig ram

It looks like it.

I just found this out on notebook check.

- i7 620M is like this:

2.66GHz Base
3.06GHz Dual Core Turbo
3.33GHz Single Core Turbo

So maybe the i5 is something similar like:

2.4GHZ base
2.60GHZ Dual Core Turbo (this is my guess).
2.93GHz Single Core Turbo

I just need to find a link somewhere that tells me the dual core speed.

The i7 has 4 cores, thus it has turbo in dual core mode too (since it disables the other 2 cores) and in single core mode (disables other 3 cores)
i5 only has 2 cores, so it can only use turbo when one processor is under load (disables the second one). So base 2,4 Ghz and turbo 2.93 as the intel site shows.

The i7 620M has 4 threads, not 4 cores (2 cores with HT).

EDIT: unless HT acts similar to 4 cores so it still disables the HT?

Weird, but the Core i5-520M also has hyperthreading (meaning 2 cores / 2 threads per core). Maybe it does disable HT to turbo boost more (the i7 part) while the i5 part only disables the actual core. Turbo boost is already complicated, mobile parts make it worse Tongue

From the looks of it, the i7-620M is just a more powerful i5 EDIT - (besides the cache) so I guess it would have that same setup notebook check mentioned:

base
dual mode turbo
single mode turbo.

And I assume the processor (either one) will run at its base speed and use one core to turbo whenever it needs to.

It is confusing Closedeyes I mean, the only info they say is it boost when it needs to... so when does it boost? When does it need to boost?
