Laptop CPU S-Spec numbers

[aniraa]

Hey guys, I was wondering if I should pay attention to the s-spec number of an Intel mobile cpu I'm trying to replace.

 

My laptop cpu got fried and the repairman said that he had one ready to swap, but it's a bit over my budget, so he suggested I try to find one cheaper in China. As I was looking through the cpu listings, I found out that my particular cpu has 2 different s-spec numbers. It just happens so that my s-spec number is a little bit more expensive than the other. Is that number negligible, or should i take the safe route?

Well, what CPU are we talking about? Because on older CPUs (on laptops that actually had replaceable CPUs), it wasn't uncommon to have one s-Spec for the BGA version and another s-Spec for the socketed PGA CPU.

It's a 9750H

The difference between the sSpec SRFCP and SRF6U is the different stepping. The SRF6U is the U0 stepping (6-core initial Dies) and the SRFCP is the newer R0 stepping (6-core improved stepping), which could bring ever so slight performance increases and more efficiency due to improved voltage curves. So I assume that the SRFCP is more expensive, but should be slightly better. The thing is, the BIOS has to support it. So if I were you, I'd go with the same sSpec number because some motherboard manufacturers of the desktop equivalents released BIOS updates to support the R0 steppings.

Thank you so much for the explanation!
