i5 vs i7 vs Ryzen 5 5500u

Could you tell me please which of them is more reliable, especially in terms of overheating?
- Intel Core i5 1135G7
- Intel Core i7 1185G7
- AMD Ryzen 5 5500u
Not going to play games or overlook. Thanks!

 

Talking desktop or laptop here?

Since ADL 12th gen has been released for desktop I would skip both of those Intel options and look into the 12 series as there are significant tech advances this time around.

 

Those are mobile CPUs.

 

Unfortunately, can't pick 12 series. Though thanks for the advice.
What would you choose among those three?

 

Personally I stick with the I7 models as a happy medium between cost / performance.

 

Too many unknowns to answer correctly.

What notebook is this? Can it handle 28W+ cooling needs? Does it have the headroom in the design to do so?

Is cost a factor at all? What is the $$$ difference between the identical model, but with the i5 vs. the i7.

What are the actual workloads? Is battery life a factor? What are the RAM and SSD configurations here? What about the screen (1080p, 4K, OLED)?

Technically, none of these will overheat, if used as designed. They will all throttle down to stay alive.

A ThinkPad T15 G2 (for example) with an i7-1185G7 that is rated with a 30W+ cooling design is a good match.

As is a ThinkBook 13s G2 with an i5-1135G7 (that is much slimmer, lighter, and has a much lower cooling design point).

The processor on its own means (and is worth) little. The devil is in the details.

Ultimately, the performance difference between the two processors (yeah; AMD is not included - overall, Intel is the better platform, by far) will be very similar in the same chassis. At maximum performance and with proper (T15 G2 level) cooling, the i7 will give better performance at the expense of battery life. In the same chassis, the i5 will give a quieter experience and better battery life. In a cooling-limited design, the performance may even go to the i5 over the i7. The biggest difference between the two processors is the iGPU performance between the two processors. Not all G7's are created equal (if that is important here).

Without knowing any of the above, the i5-1135G7 is the processor I would recommend based on the info given. Along with 16GB+ of RAM, and at least a 1TB SSD that is OP'd by 33%. And not in a Dell, HP, or Samsung notebook (almost any model of those manufacturers is guaranteed to 'overheat').
