Oops! I just realized my subject's wrong...
The slower 2.0GHz CPU has the larger cache 1MB.

I would take with bigger cache, but if the 3200+ rating is the same then 50/50, some applications like more mhz clock and other more cache.

I have similar speed cpu in my Socket754 build: Re: Socket 754 DOS/Win9x Machine

Check the actual CPU model number online and see if one of these is a Venice core. Venice cores are newer and use a lot less energy compared to the old Clawhammer ones. As such, they also OC much better too... or if you're not into that, then the advantage is you can under-volt them quite a bit and get even lower power consumption. I forgot how low I could push my socket 939 2 GHz Venice, but I recall something like 1.175V or the like on stock voltage. OC'ed to 2.5 GHz, I can still under-volt a little down to 1.35V, IIRC.
That said, even the Clawhammer cores don't undervolt too badly either. I forgot what I had set one of mine, but something along the lines of 1.3x Volts for the stock 2.2 GHz core clock instead of 1.5V. The difference: about 10-20ish Watts in power consumption (and thus, less heat for the CPU cooler to deal with.)

Sure, I can use the Venice variants and the Turion 64 as well. But they all have 512 cache like the Newcastle.
Only the Clawhammer has 1MB cache but it's slower. So, that's why I asked if I should expect a noticable performance difference.

I would get 2.2Ghz with 1MB cache. That's the Athlon 64 3400+ in my signature. Higher speeds are very rate on socket 754.

It is cooled by copper version of Thermaltake Max Orb. I also have Zalman CNPS7700 that I'm not using.

There are two pitfalls with socket 754
- do not use more memory than 512MB on Windows 98, which limits usability in Windows XP unless Windows 98 is patched to fix instability with lot of memory
- problems with AGP in Windows 98 on newer boards or boards with new BIOSes. AGP is not initialized correctly and performance is very poor. Only early VIA boards do not have this problem.

Turion 64 (Lancaster core) has even 1024 kB L2, not only 512. There was 2 lines of them, ML and MT with 35W resp. 25W TDP. Could be simple overclocked, if you have good board, supported high base clock.

Thanks. This was a good call. I checked Turion again and actually ML-40 is going to fit the bill. I think it's the winner.

My setup has Turon 64 with 1MB, faster ones with 1MB added below.

I consider buying an Athlon 64 3200+ for a socket 754 board.
Which of the two versions should be faster - the one with the bigger 1MB cache or the faster 2.2GHz one?

I'd target:
ADA3400AEP5AR, CG revision Clawhammer (improved IMC)
or
ADA3000AIK4BX / ADA3200AIK4BX - Venice E6, lower voltage and SSE3

Originally, I considered a Clawhammer, but since we started talking about Turion, I'm going to chase an ML-40. ML-44 is "unobtanium".

My motherboard is MSI K8MM-V. The only source for CPU compatibility I found was here:

I think S754 Mobile Semprons also work with that motherboard, but they have 256kb max @ 2GHz, so Turion64 should be better choice + 64bit, some Semprons are only 32bit/sse2 and some are 64bit/sse3. Just you know default S754 coolers does not fit out of the box for Turion64 (height issue) and you can take cpu heat spreader off from broken or slower regular s754 cpu or use special cooler for Turion 64.

Well, I ordered an ML-40 today.
Now, I'm against the challenge of dealing with cooling/heatsink. I can't find info on readily available cooler kits. I guess I can borrow the heat spreader from my currently mounted Sempron 1.8GHz.
I also saw some suggestions of using a silicone pad instead: Low profile CPU fan for desktop Turion 64

Where did you order ML-40? I dont have faster than ML-37 at the moment.

This cooler fits directly to the Turion64 without any modification (no heat spreader needed, use directly with thermal paste)

Thanks for the links!
Oh, boy! The price for the cooler on "ePay" you linked is equal to the shipping costs to Canada. But I may cave in, if I don't find something else.

Huge price, i skip at the moment. 😀

What are cooling options with Turions, only Zalman CNPS 7000 / 7700 ?

Cheapest solution, regular Sempron 2500+ S754 or what S754 free CPU you have and take the heat spreader off gently.
I have used razor blade to take heat spreader off, after that use any compatible cooler that you like on top your Turion64.
Also use bit thicker thermal paste under heats preader, but any thermal paste will do, just center the heat spreader well.

so, transplanting IHS to Turion?

Yes and use bit thicker thermal paste under heats preader, but any thermal paste will do, just center the heat spreader well @ installation.
