Hi.
I am wondering:
What is the lowest-TDP desktop intel cpu for LGA 775?
That can be easily replaced, i.e. not glued on mobo.
Lowest heat generating cpu at full load, not caring about idle states, or bang per buck etc..
Thanks!
Celeron 4xx series is 35W TDP. Celeron 420 is the slowest at 1.6ghz.
It's single core, so it's usefulness is a bit... limited. (there's a couple of good recent YT reviews about these, Win10 basically eats the whole thing.)
That really depends on how much your motherboard is flexible for tweaking. If you can manually set multipliers and voltage - high-end CPUs are much better option.

Assuming that mobo is not flexible and everything is set automatically, would you agree on celeron 4xx series?
An lga775 mobo somehow found me but it had a prescott 2M HT 3.4ghz, I could even feel how warm the case gets after some time.
So I quickly found a celeron 430 (1.8ghz) for cheap (1.5$) from my neighborhood, TDP is only 35W vs preshot's 84W, saving about 50W!
Now it runs much cooler and happier.
Another thing, I don't like multi-cores, hyper-threading, eist, etc..
So I wanted the simplest and coolest cpu possible.
I can choose to use with it: dos/win98, or win7 at most. (don't like winXP that much)
The mobo is ASUS P5LD2 SE

Now if I somehow could make it run at 533mhz fsb at 1.2ghz it would be even cooler!
But I found no such selection in bios.
There are some 771 Xeons in low power models that will mod for 775.
L5408 is 40W 2.133Ghz x4
to
L5430 @ 50W 2.667Ghz x4
Then also you can go down to the 2 core...
L3310 is 45W 3.0Ghz x2 .... splits the watt difference but you get higher single core speed if you need it.
There's the "S" versions in the Core 2 Quad range for 65W instead of the 95-125W usually quite spendy, I went for a cheapy L5420 to stick in my "shoebox ITX" s775 ... have not seen any particularly low power in the C2Duo or Pentium Dual Core, but cache reduction in 2nd should mean "it heats up slower" to 65W TDP than equivalent C2D
If you can't do conroe on the board, there's some 65W version of Cedar Mill Celeron D

If you have an i865 board, could it be the perfect 98SE CPU?

No, because you still get benefit from larger L2 cache on fully fledged Core 2 Duo.

Cache difference is inside 10% performance variation IIRC and not relevant on every workload. Therefore, if you can get a 450 over 3.3Ghz without busting 45W then yeah it's more ideal than the dual in the specific situation of Win98 and maximal performance at minimal power.... you can get C2D 8x00 up to 4.5Ghz though with a lot more watts, 125-140 I think.
But 450 is pretty good, getting high end Pentium 4 performance for a third of the watts.

Cache difference is significant when it's 512Kb vs 4Mb. Or even 6Mb.
