Intel Xeon cpu?

Hi, I am curious if a Xeon processor is more powerful than a core 2 quad processor? Below are the specifications of the Xeon cpu’s (which I am considering purchasing). Also the core 2 quad specs of the current cpu installed into the machine.

LGA775 MOD Intel Xeon E5345 2.33GHz CPU QC 8MB 1333 SLAEJ No Need Adapter
Or this Xeon:
Intel Xeon X3450 2.66GHz 8MB/ 2.5Gt/s SLBLD Socket LGA 775 CPU

model name : Intel(R) Core(TM)2 Quad CPU Q8400 @ 2.66GHz

What are your thoughts on this?

Thanks

I see this Xeon also: Intel Xeon X3440 2.53GHz Quad-Core (BX80605X3440) Processor

@panorain depends, you need to look at the specs of each one and compare;

None of the three are LGA775 socket;

Ok, I will review this material you send above.

This cpu has a board of some sort attached so it plugs in:

It states: LGA 775

@panorain No, that’s all part of the CPU… https://www.cpu-upgrade.com/CPUs/Intel/Xeon/X3450.html

@panorain Check your system, some examples here;

I see the link you sent cpu supports ddr3 memory not ddr2 memory. So the cpu will not work I see now. Socket is 1156 also on the information link. I seem to have forgotten how to display the current chipset.

@panorain /sbin/lspci will list everything…

Yes, I recall to add -nn to the end /sbin/lspci to display numberical id’s. Are you saying mostly these Xeon’s even if 775 socket require a certain chipset and or ddr3 type memory also?

@panorain very likely, but if you check the system manual, if it has a list of CPU’s then that’s it…

That’s what I was contacting Lenovo about. It seems to have been removed from the website for the M57p. I’ll check around some more for that. Hardware service manual is still available and I have that now.

It is possible to use LGA771 Xeon on LGA 775 mobos:

ILL LGA 775/771 CPUs have no support for SSE 4.2 → no support for x86-64-v2.
Retrocomputing is your hobby?

Thanks for this information. I have this desktop currently right now for lack of another.

It appears yes the Xeon X3450 is more capable. Thanks for link to this also.

Core2 Quad Q8400 socket = LGA775. Intel Xeon X3450 is installed in LGA1156. It will not install on your motherboard. Be careful.

Just noticed the installed cpu here is V2:

This Quad Core supports V2 as per: https://en.wikipedia.org/wiki/

Okay, the fastest options for LGA775.

I did check Q9650 versus your current CPU and only 14% gain, not something I would put effort in.

Fastest LGA771 - Intel Xeon X5492: +40% to speed, but 150 W.
Xeon X5472 - 120 W.

https://www.cpubenchmark.net/compare/1041vs1493/Intel-Core2-Quad-Q8400-vs-Intel-Xeon-X5492

Without SSE 4.2 this is x86-64-v1 = x86-64 only.
