What is the maximum all-core Boost Clock on i5 7500 ?

[thepaleobiker]

The Kaby Lake i5 7500 has base clock of 3.4 GHz and maximum Boost Clock of 3.8 GHz : I'm assuming the 3.8 GHz is for a single core : What is the max all-core boost for the i5 7500 ? I cant seem to find this information anywhere....

From the last link above, CPU Userbenchmark, it looks like the average 4 core clock is 3.6GHz... is this the max all core boost clock?

If someone already has this CPU and could clarify this, it'd be a huge help. Thanks!

Sincerely,

I think this partially depends on your motherboard. Some motherboards have a feature called "multi-core enhancement" which causes all your cores to turbo boost to the max boost clock.

So if you have such an option enabled in your BIOS, your boost clock is 3.8GHz. If you have two monitors, this would be trivially easy to verify by running a well-threaded app or game on your main monitor with CPU-Z running on the secondary.

Interesting - so it might be linked to my mobo. I've an MSI B250M Gaming m-ITX Mobo, I'll go dig into its specifications. Thank you for this input!

Are you sure that's true for locked SKUs?
That feature is simply a mobo OC not something Intel supports so one would assume it doesn't work with locked SKUs. Would be interesting if it is available.

It generally does work for locked SKUs on overclocking chipsets. Z chipsets.

My Z-97 board will run a 4790S at 4ghz on all cores under load, and a 1231-V3 at 3.8ghz on all cores under load, for example.

3.8 is the single core turbo for the 7500, some overclocking boards might allow all cores to run at 3.8ghz under load, since the multiplier can be set to 38.

Thanks any clue if the clocks are sustainable or they throttle at load and based on what?

Thank you sir - I'm guessing all 4 cores are at 3.6 GHz in this scenario ? I'll get my 7500 by Friday, maybe I just need to wait to run some tests to capture core clocks over a multi-threaded task.

Thanks again!

Throttling would likely be thermal, but I saw no throttling at all with stock coolers.

XTU will teach you how many different kinds of throttling Intel has.

My non K 7600 hits 3.9GHz all 4 cores loaded, 4.1GHz to a single core. Really is worth buying the top shelf non K CPU for KBL.

They are sustainable, the Skylake i5 only reaches 65W limit close to 4Ghz under very heavy AVX load (Prime 95). Any other type of load would keep a 3.6-3.8Ghz KBL w/o SMT well south of power limits. The only scenario I can think of where throttling may occur is combined CPU + iGPU load, but in that case CPU would not be a bottleneck even at base speed.

I got a deal on a 7500 at $180, and it'l still be good improvement over the G4560 ! That non-K 7600 as well as the non-K i7 7700 are both efficient yet beastly CPUs.....
