i7-8700
- The i7-8700 has higher Level 3 Cache. This is useful when you have substantial multiprocessing workloads, many computationally intense simultaneous processes. More likely on a server, less on a personally used computer for interactive desktop workloads.
- The i7-8700 has more threads. Larger programs are divided into threads (small sections) so that the processor can execute them simultaneously to get faster execution.
- For some games, a cpu with a higher clock speed, or in a technical name IPC (Instructions per clock), has better results than other CPU’s with higher core count and lower core speed.
- The i7-8700 has a higher turbo clock boost. Turbo Boost is a CPU feature that will run CPU clock speed faster than its base clock, if certain conditions are present. It will enable older software that runs on fewer cores, to perform better on newer hardware. Since games are software too, it is also applicable to them.

intel core i7 — Will Idle temperature increase when upgrading i5-8400 to i7-8700?
I have a passively cooled i5-8400
which runs at about 34-40 degrees for most of the day (peaking at about 60 degrees periodically) using a Cooler Master Hyper heat sink and a single 20cm Noctura case fan that runs at minimum (noiseless) speed until it needs to shift some warm air out of the case.
The applications I use would benefit from a hyper-threading boost and rather than upgrade everything I’m thinking of swapping out the cpu for an i7-8700
Whilst they are both 65W TDP, I am aware that hyperthreading, and the extra clock speed, can increase temps, but I cannot find any concrete figures of expected temp increases in a like-for-like environment.
Has anyone gone through a similar process and can tell me what they observed?
Here is a typical day for my i5-8400 system:
Thanks

The CPU-World article
Intel Core i5-8400 vs i7-8700
gives both CPUs identical thermal properties.
Both CPUs are rated for the maximum of 100°C (Digital Thermal Sensor),
from which you are very far with a maximal running temperature of only 60°.
It should be noted that the two CPUs are almost identical, as the i5 is
only an i7 that didn’t make the mark on performance. Temperature is directly
related to power consumption, which is identical for both.
I don’t think that you will see a big difference between the
two processors as regarding the temperature.

I took the plunge and got a used i7-8700 off eBay…
For me at least, the temp differences are very little — in fact, if anything it’s running a tiny bit cooler! — but that could be down to a number of factors beyond the CPU itself.
However increased clock speeds and hyperthreading do seem to have given me enough of a boost to be worth while — glad to be getting a little more more life out of my system before a bigger upgrade in the future.
