Upgrading the processor on a laptop, which is better?

Question

laptops

Hello.
There is a laptop MSI GT70 2PC. Decided to give the old man (the 6th year went from the date of purchase) a second life.
In it (as I recently accidentally discovered when searching for a BIOS for flashing) there is an upgrade option, you can change the video memory and processor.
I smoked forums, articles, numerous sites, came to the conclusion that the video memory from the gtx 870m will be replaced without problems by 970m or 980m, for example.
But I don't fully understand about the processor.
Available i7-4710mq. I realized that the socket should be the same as mine (PGA946). On the official MSI forum, when asked what the most productive processor can be installed without problems, I was answered at least i7-4930MX. I compared them, they seem to be compatible, but there is one thing. TDP at 4930mx (and 4940mx) is 10 higher (45>55 w). Will this greatly affect performance and is it worth picking up a processor with the same TDP, for example 4910mq, or will everything be fine and can be replaced without problems? Although performance will improve more when replacing video memory, as well as adding an SSD and a second stick of RAM, a lot also depends on the processor and its frequency.
So this question is of interest - is the TDP number increased by 10w very critical? Or should you leave what you have?
Motherboard, if anything, ms-1763.

Answer 1

Not video memory, but an MXM 3.0b video card can be replaced there. 980_M_ is (and it's not the same as 980), and 1060 is not mobile, which will be much faster, so it's better if the budget allows.
Core i7-4910MQ is better. But the difference won't be big.
From ssd and memory in daily work, the difference will be most noticeable. From video and memory in games.
From replacing the processor, in your case, it will be noticeable mainly in benchmarks, and a few fps in some games that are greedy for the processor.

Answer 2

I had a laptop with i7 4720hq and 860m. What can I say: this 37 watt AI 7 pulled out the entire assembly, since there was not enough cooling, the video was hot, and only 37 watts of tpd of the processor allowed squeezing juice from the laptop. You can put a percentage of 10 W more powerful in a laptop without any problems, everything will work. But the gameplay can get worse, because with excessive heating, both the video card and the CPU will go into throttling and reset the frequencies. Infa cell. You want to install very powerful pieces of iron, but the laptop cooler is not designed for them. Performance in general will increase, but rests on cooling. My 860m didn’t even work for a minute at 1000+ MHz, it always clung to 900 MHz, or even 860 MHz (in the summer I rolled at +37 on the street on vacation), so bro, don’t waste money in vain, it’s better to take a well-thought-out system with a supply of coolant .
