A Core i7 laptop at 47K, so why desktops are costlier?

[BhargavJ]

I live in India, and the prices are Indian Rupees. These two laptops have an i7 processor, and yet they are priced below 70k:

If we were to assemble an i7 desktop without a graphics card, it would still be very costly, at least 80 - 90K. So why are the laptops so cheap?

Shitty graphics and a last-generation Core i7. Plus a desktop with a Core i7 doesn't need to cost anywhere near as much as you claim.

Here's a desktop with a newer Core i7, similar or better specs otherwise, and no graphics card. Priced at $626 which is just over 38k rupees. Of course, it's very basic on many points, but so is that laptop.

Edit: Wait a minute - that 47K laptop doesn't come with Windows. So you can shave another $88 (5K rupees) off this price.

Laptop CPU and GPU are way different than Desktop CPU and GPU .

laptop cpus generally have a lower base clock speed but a higher turbo speed hence why most laptop i7's can beat even a desktop i5 4670k as they have 8 threads.

Not true. The turbo clocks are still just as good on the desktop or even a little better. But the laptop CPUs can drop back a lot further, to allow for the compromised cooling in a laptop.

Now, a laptop Core i7 may outdo a desktop Core i5 in some cases, but that's because you're not making a fair comparison. A desktop Core i7 will outperform the laptop Core i7 every time.

If you allow for the cost of the built-in monitor, mid-range or low-end laptops are not significantly more expensive than equivalent desktops. But at the high end of laptops, you pay a big premium without getting close to what (much cheaper) upper midrange or high-end desktops can do.

Edit: Just to confirm the clock speed thing, the fastest laptop (Haswell) Core i7 turbo clock is 3.9 GHz on the ludicrously expensive Core i7-4930MX. That's over $1000 MSRP just for the CPU.
The fastest desktop (Haswell) Core i7 is 3.9 GHz on five different models, the cheapest of which are the 4770 and 4770S ($303 MSRP).
