Yes, 2.4GHz
vs 3.4GHz
is a big difference.
However you're comparing the same processor, and they're both capable of achieving 3.4GHz
. For the i7-4700MQ, 2.4Ghz
is the base speed and 3.4Ghz
is the turbo speed.
If the processors had otherwise different clock speeds (and all the other features were mostly the same), there would be a pretty big difference in their capability.
Note that there's other features of a processor that can out weigh small differences (ie 0.1 - 0.2Ghz
) in clock speed. Features like:
- the number of cores
- hyper-threading enabled
- cache sizes
will also affect the comparison between two processors.
Whether or not you would notice these differences also depends on what you're using the computer for. If you aren't using your computer for gaming, video/music rendering, or some other computationally-intensive task, the difference will mean very little to you.
Apart from the answer:
If you want a computer that performs well for general tasks (ie internet browsing, document editing, etc), get a computer with an SSD. Especially when you're buying a laptop, SSDs will increase battery like and drastically increase boot-time (and other drive-intensive operations). When it comes to general-purpose computing, SSDs make more of a difference than faster RAM and CPUs.
Not to judge your purchase, but both computers come with 1TB 5400RPM
drives - that is slow. Unless you actually need all that space, you will enjoy the capabilities of an SSD more.
And if you are looking to buy an HP laptop, do some research to make sure that none of the ports or internal parts are proprietary - HP is notorious for this.

– Ƭᴇcʜιᴇ007 – 2013-08-08T17:18:10.860Specs for that processor are available from Intel and if you read that, it tells you straight out: 2.4GHz with max frequency (Turbo) up to 3.4GHz.
– Ƭᴇcʜιᴇ007 – 2013-08-08T17:21:33.3271A GHz (gigahertz) refers to the clock speed of a processor. It used to be highly relevant in the era of one-core CPUs, but it's less significant now. Still, it's a (very rough) indicator of computing speed. However, it strikes me as weird that the same processor could be listed with such a wide difference in clock speed. Are you sure it's the same? Maybe it's a typo on the website. – Timst – 2013-08-08T17:17:18.950
I'm pretty sure- here are the links to the sites: Toshiba Satellite

– Jonathan Lam – 2013-08-08T17:20:14.447Toshiba's description says "up to 3.4GHz". It's exactly the same CPU, but they are trying to trick you into thinking Toshiba is faster. – gronostaj – 2013-08-09T10:09:51.873
I guess so. So I'll choose the hp envy. – Jonathan Lam – 2013-08-09T12:44:26.557
