3.5ghz processor vs 3.3ghz processor?

[Nibbets]

Not sure if this belongs here or not but anyway...

 

My son is looking to buy a flight sim game (xplane 11) and when he checked on can you run it it said he met the minimum requirements but not the recommended. The recommended processor is an i5-6600k and he has an i3-12100f. Would that 0.2ghz really make any difference?

Clock speed isn't that important, what matters more in this case is how much work it can do per cycle. A 12100F can do more work per cycle than a 6600K, even with that clock speed deficit.

 

That's why a 3.4GHz Pentium D can get absolutely curbstomped by a 2.4GHz Core 2 Duo.

The 12100 is better than an old 6600k, sure clock speed is a bit lower but IPC is way better, resulting in moaar powwwaaaa

No. the 12100f is a very capable CPU. the clock speeds aren't the only thing that matters. The 12100f will outperform the 6600k by about 30 percent. keep the 12100f. also, the words "i3" and "i5" don't matter as much as the CPU generation. the 6600k is 6th gen, while the i3 12100f is 12th gen. the 12100f will definitely be a lot better than the 6600k.

the 6600k is up to 3.9ghz, the 12100f is up to 4.3 ghz, even if the 12100f was running at a lower freq than a 6600k, it would absolutely destroy it

Its more complex than just clock speed when looking across architectures/lithography. The transistors per core between a 6600k and 12100f aren't the same too, nor is the IPC as fibberdipper mentions. The architecture and how effectively it uses that clock speed aren't  the same.

 

Its almost always better to go with newer architecture over older architecture, especially if we're talking anything before 12th gen Intel or Ryzen 3000.

 

Intel Core i3-14100 vs Intel Core i7-7700K Benchmark, comparison and differences (cpu-monkey.com)

 

Just looking at Cinebench R23 scores, which generally doesn't care for the extra cache the 14100 has nor higher memory bandwidth, its about 50% more performance in both single and multi thread performance. I intentionally used the more powerful 7700k as an example here too.

So pretty much to sum all of it up, just tell your son that he meets the recommended specs, and his processor is much better than the recommended one. No need to upgrade anything.

Thank you everyone. I was pretty sure he'd be fine with what he has but I wanted to double check.

You need go really low clock to actually start see diference in games. You won't see difrence even 5 Ghz vs 4 Ghz with same CPU.
