Which processor is better? Intel Core i3 6100U vs Core i5 5200U

[Mahesh Abnave]

My brother wants to buy a laptop which fix in his budget. His primary goal will be productivity. The applications he use are mostly Microsoft Word and Browser. i5 laptops are getting out of budget. Some are there within the budget, however they lack good reviews. So I started thinking whether I should look for i3, if at all they are equally good at the performance.

Brother need the productivity laptop.

I am currently hooked to 2nd gen i7 2630QM (quad core, 2GHz base, 2.9GHz turbo boost) that came with XPS 15 2011 edition.

In office I use i5 4310U (dual core, 2GHz base freq, 3GHz turbo boost),

I do development work mostly on both machines. So personally I have never experienced i3.

Will Core i3 6100U prove good productivity laptop? Currently most i5 laptop have 5200U variants. On specs, 6100U has better base frequency than 5200U (2.3GHz vs 2.2GHz). But it lacks turbo boost. Also it has better memory bandwidth (34.1GBps vs 25.6GBps). On specs it looks ok, I mean not substantially slower than 5200U.

But cpuboss says i3 will be slower: http/cpuboss.com/cpus/Intel-Core-i5-5200U-vs-Intel-Core-i3-6100U

Can someone shed some more light? Will i3 6100U prove to be very bad for productivity laptop.

The i5-5200U is only slightly faster than the i3-6100U based on benchmarks: http/cpu.userbenchmark.com/Compare/Intel-Core-i5-5200U-vs-Intel-Core-i3-6100U/m22169vsm37381

Generally, they both are equally weak laptop CPUs based on rankings.

The 5200U will boost to 2.5GHz with both cores active and 2.7GHz with one core active. That clocks speed advantage will keep it at least on par with the 6100U in multithreaded performance, and ahead in singlethreaded. But it's not like it's a big difference. For basic office work you'd be hard pressed to tell the difference.

CPUboss is pretty inaccurate. I mean look at the Geekbench 3 AES test, they've simply mixed up the units, shifting the result by 1000x off what it really is.

for powerful laptop processors, go for HQ suffix models like i5 6300/7300
