Intel Equivalent of AMD Sempron?

[Pumo]

Recently a client gave me an old computer of hers to fix it, but after many tests I made, it seems its motherboard is gone for good.
It has a Socket AM3 Sempron CPU, if I'm not mistaken that Sempron should be a 145 (I think is the only one that was made for the AM3?).

As a small favor I thought of giving her for cheap an old Motherboard+CPU that I have stored around to replace her failed one, but it's a Core 2 Duo from Intel.
Now the problem is I'm not that much an AMD user since the early 2000's, so I lack knowledge about some of the AMD architectures from past years.
I would like to know what is the Intel equivalent of an AMD Sempron 145, to make sure it is actually a good deal for her.

While this is by no means an expert opinion, I would probably compare a Sempron 145 (from 2010) to Celerons from 2008-09. A Sempron 145 would seem to be almost equivalent to an Intel Celeron E3200, with the major difference that the E3200 has 2 cores to the 145's 1 core (but the single-core performance appears to be near identical, for example). For a single-core comparison, a Celeron 450 would probably get similar performance if it had the same clock rate, but the 145 is clocked at 2.8 GHz while the 450 is at 2.2 GHz. A Core 2 Duo ought to be faster than a Celeron (unless the Celeron is much newer, as in by 8-10 years).

145 doesn't appear to be the only AM3 Sempron; there are both Sargas and Regor models (130, 140, 145, 150, 180, 190).

Ok, thanks for the info, this is very useful!
It seems that if everything is OK with my Motherboard it would be a pretty good deal for her.
