Desktop vs Laptop CPU

[dl8860]

Work are rolling out new laptops/PCs and we have a choice of which spec we'd like.

I have my eye on a DELL Latitude E6540

Intel® Core™ i5-4300M Processor (3M Cache, up to 3.30 GHz. Dual-core)
8GB DDR3L (2*4096MB) 1600MHz. Max 16GB.
128GB Mobility Solid State Drive (SSD)
AMD Radeon® HD 8790M Graphics 2GB GDDR5

I'd like to know how the processor on that would compare with that in my current Desktop, i5-2400?

My CPU knowledge has dropped off the map in recent years

Thanks

Hmm.
Haswell's about ~15% better clock for clock (Probably closer to 12.5%).

HT adds about 20% in multi-threaded scenario's.

Its normal clock speed is 2.6GHZ (Which is closer to a 3.2GHZ sandy core)

So it's about ~70% of your CPU at a very rough guess, probably closer to 65%.

One thing you have to bear in mind is that i5 on laptop is only 2 core 4 threads (with 2 HT), where as desktop's i5s are 4 cores.
