Can I compare a cpu from a desktop with a cpu of a mobile ?

can I compare a samsung s4 cpu with a intel i7?

How and a link please

best Regards

Comparing a core i7 to a samsung S4? Rest assured the intel core i7 is about a million times faster.

I'd like to say that's an exaggeration, but it might not be. The SOCs used in those phones are not even remotely close to the same level of performance. But as far as benchmarking, it isn't straightfoward because mobile devices use a different OS than intel desktop CPUs. But simply on a specification basis, the smartphone SOCs are not even on the same level really. Compared to a core i7, not even close.

They don't run the same software, so no.

Generally speaking, a good desktop CPU is about 10 times as fast as a good mobile CPU.

I dont how you came to that ridiculous conclusion. that would be like comparing an old 1.86 E6300 to today's 4770k. the truth is there are high end mobile cpus that are only tiny bit slower than a 4770k. for example a 4900MQ is only 10% slower than the 4770k.

Mobile CPUs are a bit slower when browsing facebook. They really can't be compared when they are doing more intense workloads.

what is with the ignorant comments about mobile cpus as if they are all slow? that would be one hell of a slow cpu that has trouble with facebook.

I should clarify. It's not really the cores. Most mobile cpus are crippled with emmc bandwidth and considerably worse memory controllers and no fast io. Not to mention that the frequency and power limits on mobile cpus are completely different. No you can't just scale them with the same architecture. It doesn't "just work" to crank frequency and voltage no matter what forum trolls will tell you.

If your workload can fit in the local cache sure the cores can actually perform quite well. When you are running workloads such as simulations and compilations that can last hours to days and use up multi-gigabytes of memory then no you can't really compare the two.

Most mobile/arm people will quote performance per watt at a given frequency for workloads that don't cache miss much. If you twist the numbers that way then the mobile cpus are pretty amazing. If you want absolute performance then it's not really close. Two different optimization points, two different results.

TLDR: no they aren't comparable except for certain workloads

We're talking about phones, not laptops.

As per the OP's example, I think he's asking how ARM CPUs compare with Intel's desktop offerings, not Intel's mobile offerings vs Intel's desktop offerings.

oops my bad. I saw Rakehellion's comment and replied without even looking at the OP.

Thanks everybody.
My special investigation is about manage a 700000 registers database with android.

is recommendable ?
Is possible ?

It is possible. However, keep in mind that that the workloads that these processors will perform are mostly not going to be the same.

With that in mind, here you go.
