Interchangeability of processors?

Question

Iron

Hello!
Can anyone suggest how old processors from one manufacturer are replaceable with newer ones without replacing other laptop components.
On the example of i3-330M and i5-2520M.
The same x-ki:
- Case size
- Cache memory
- Bus type
- Instruction set
- Lithography
- Number of cores and threads
- Thermal power
- Memory type (DDR3-800/1066 for i3 and DDR3-1066/1333 for i5)
- Number of memory channels
Differences:
- Instruction set extensions (SSE4.1, SSE4.2 and AVX)
- Maximum temperature (90 and 100) (this difference, I think, can be eliminated with a cooling pad)
- Graphics system lithography and IMC (45 and 32)

Answer 1

All substitutability dances at 90% of the socket for the processor and 10% of its support in the BIOS. Now, in the current realities, never once when upgrading computers (laptops / desktops) did it hit the last 10% - apparently, it is easier for a manufacturer to rivet one BIOS with support for everything and immediately to "related" models than to prepare their own software for each.
So if you need a replacement, look for the most powerful one that matches the socket and check the TDP (because the standard cooling system, if we are talking about laptops, may not be able to cope with changing the B960 to i7).
Using the example of your two processors from the question: just drive them both into Google, go to cpuboss or cpu-world, in this case the first link led to CPUBoss.com .
There we scroll to Details and see different sockets:rPGA 988B and BGA 1288 . If the sockets matched, you would need to pay attention to the Power Consumption section and the TDP and Typical power consumption parameters - if they match, then we set it with a pure soul, but if the new processor has a higher value for these parameters, then there is a reason to think about the risk before replacing.
I made a mistake, looked at Intel's website - both really come with rPGA 988B - so you can safely change. If the sockets are different, or the native one still has BGA (that is, the processor is soldered) - forget about the upgrade.
There is a mention of "max temperature" in the question - that doesn't say the new processor is hotter, just the wider temperature range it can handle.

Answer 2

Start simple: find out if your processor can be replaced at all or if it is soldered to the motherboard. Both processors are available in BGA version.
This is the maximum allowable temperature, not heat dissipation. Passport heat dissipation (TDP) is identical.
