Determining Actual CPU Performance

Hello!
I've been searching for a cheap laptop for homework, and music creation. (Nothing too complex because I can master tracks on my higher-end desktop + it's all shitty synths :sarcastic:)
My budget is 350$, and I'm trying to get the best performance/price.
However, I've found it to be quite difficult to determine the actual performance behind a CPU.
The usual CPU's for ~350$ are Celeron's and i3's.

To my knowledge, the best CPU I could find was the Celeron N2840, which is dual core 2.6Ghz.
However, the i3-4030U, which I've seen gets better benchmarks, is a dual core 1.9Ghz.
Here is the benchmark link: http://cpuboss.com/cpus/Intel-Core-i3-4010U-vs-Intel-Celeron-N2840

Am I missing something? It would make sense to me a dual core 2.6Ghz should be faster than a dual core 1.9Ghz... Yet benchmarks say otherwise.

If anyone has any insight to these lower-end CPU's I would be very appreciative.

Hi,

You can simply look at PASSMARK for a rough guide:
https://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i3-4030U+%40+1.90GHz

The SINGLE and TOTAL are important.

A dual-core CPU with hyperthreading with HIGHER single thread performance can often beat a quad-core CPU with higher TOTAL but lower SINGLE.

A modern i3-4xxx/i3-5xxx is a great choice.

*CELERON's are a different Intel architecture optimized to save money and they are awfully slow. I'm not sure if these laptops also use a cheaper motherboard chipset but I bought one recently and it had me scratching my head due to the slow bootup and other processes (same hard drive as an i3-4xxx I tried which was way faster).

AMD?
AMD is normally a lot slower than intel but in the case...

First off, ghz does not represent how much work can be done per cycle. It represents how fast the cycle gets done. A 2ghz processor that does 1 item of work will theoretically perform the same as a 1ghz processor that does 2 items of work a cycle.

That being said, try looking into amd apu laptops. Intel honestly, in my opinion doesn't have that much in the budget market that is actually decent.

Thanks for the response.
I figured it had something to do with that, but is there a way to find out how much "work" a processor does in a cycle? I don't see any information like this on Intel's website.
I know absolutely nothing about AMD processors. Could you recommend a netbook with a decent processor?

AMD is normally a lot slower than intel but in the case of low-end laptops they might be similar or even better. Again, try using Passmark.

Here's two more:
Pentium N3700: https://www.cpubenchmark.net/cpu.php?cpu=Intel+Pentium+N3700+%40+1.60GHz
vs
A4-6210: https://cpubenchmark.net/cpu.php?cpu=AMD+A4-6210+APU&id=2307

The AMD is slightly faster in this case, but both have FOUR cores.

*Having TWO cores is fine with a good Intel i3 with hyperthreading, but I'd stay away from dual-core Pentium/AMD CPU's as they might be painfully slow.

Again, not sure exactly what's going on as it seems like the motherboard chipset can be a bottleneck too so basically the low-end AMD/Intel laptops are going to be somewhat slow.

Thank you for your help! I found what I am going to get.
