What would a 2nd gen i5 mobile processor compare to now?

it is a bit slower than a i3 4th gen 4130

Sandy Bridge processor performance is not that much worse than current-gen processors. Its architecture is actually only 1 gen behind Broadwell. Intel uses a tick-tock cycle, alternately upgrading architecture or shrinking the lithography. So Sandy Bridge and Ivy Bridge had the same architecture, and Haswell and Broadwell had the same architecture.

The big difference will be power consumption (it's 2 generations behind) and the integrated GPU (Intel updates that with both tick and tock updates). As mentioned above, your CPU has a 35W TDP, while similar performance can now be obtained from a CPU with a 15W TDP.

IMHO the biggest drawback would be that you probably don't have USB 3.0.

he was not comparing the igp he was comparing the cpu performance in general in which if you look at notebookcheck his cpu is as about as fast as a core i5 5200u.

No it's not. And what's more pathetic, NotebookCheck is super unreliable. The only thing it's good for is the numerous consumer variants of one single model.

At its best, the i5 is about as good as a desktop i3. Why? Two cores, 4 threads. So if an Sandy Bridge desktop i3 performs as well as a high end Pentium to low end i3 these days, it doesn't really compare to the i5-5200U. i5-5200U runs 14nm, which is about, give and take it being a laptop processor, is about as good as FX-8320 vs. i5-4690K today.

Notebookcheck runs a huge slew of widely-accepted benchmarks across a huge number of laptops. Their CPU comparisons are an average of those benchmarks on all laptops using that CPU. Furthermore, they let you drill down and see each individual laptop's benchmark if you wish.

For that reason I consider it much more reliable than something like Passmark, which is just a single benchmark (well, a suite of benchmarks). Notebookcheck iis probably the best representation of an industry-wide average I've seen (i.e. averaging out the same CPU used with different motherboards, memory speeds, etc).

Not sure why you're trying to draw an analogy to desktop CPUs (and AMD vs Intel at that). As I stated, the mobile i5 is basically a mobile i3 with turbo boost. After you factor in the i5's turbo boosted speeds, you can just compare clock speeds. So after compensating for generational speedups, you can in fact compare it to a current mobile i5.

For CPU-bound tasks, Broadwell is about 15%-20% faster than Sandy Bridge clock for clock. More on some tasks, less on others. Since the i5-2520M turbo boosted to 3.0/3.2 GHz, scale that down by 15%-20% to get 2.5/2.6 GHz. Look down the list of Broadwell i5 CPUs, and the i5-5200U has turbo boost speeds of 2.5/2.7 GHz. So the i5-5200U should in fact be the modern CPU which has the closest level of CPU performance to the i5-2520M.

Comparing the Cinebench 11.5 multithreaded CPU scores for both these CPUs, they are in fact nearly identical. Super Pi (which is more reliant on memory speed) shows about a 10% advantage for the i5-5200U, which is about what you'd expect with the faster memory it uses.

THIS is more reliable than NotebookCheck.

And also, you know how AMD FX (Bulldozer) is slower than the Haswell platform? You know why? Lithography. It took more than 5 Ghz for the FX to be comparable to a Haswell i5. Because Sandy Bridge uses 32nm, my prediction is that the i5-5200U would beat i5-2410M's a$$ sore. The lithography is difference is a bit too high to say that a Broadwell and a Sandy Bridge processor performs similar.

And I stand corrected. I glanced over those laptop benchmarks, and I was correct. i5-5200U wrecked i5-2520U in benchmarks. At least, to my eyes it does.

And as for why I pull to desktop CPUs for comparison, it's the easiest way for me. Why? I know the desktop numbers much better than my laptop ones. And that's fine, because they're comparable (more or less).
