subzer0, thank you for your contribution to the thread.
Your first point:
|The L2 cache sizes are identical. The Xeon 3040 and 3050 chips have 2MB L2 cache like the Core 2 E6300 and E6400 chips. The Xeon 3060 and 3070 have 4MB L2 cache like the Core 2 E6600 and E6700 chips. There is no Level 3 cache used on either series of chips. This is confirmed by the specifications found on the Xeon 3000 boxes; You may recall some confusion when the Xeon 3000s first came out where it was thought that they all had 4MB L2 cache like the Xeon 5100 (Woodcrest) Series. This confusion has since been cleared up by Intel. Unfortunately Intel has not corrected the wrong information found at the Xeon Comparison Chart where it shows that the Xeon 3000s have an L3 cache and no L2 cache.
This is correct, and incorrect. The original revision of the 3000 Xeon series contained within them L3 ECC cache. With the later revisions, due to upgraded functions, L2 cache was implemented.
The Xeon 3050 I have tested contains a 2MB ECC L3 memory line. This is because my original Xeon is one of the first to have been produced when ECC L3 was used, apparently.
I believe the earlier chips contained L3 cache due to the information from the internal cache Data Array and the position of the cache within the physical structure of the chip itself, and the Intel "Tech" logs for the Core Micro-Architecture implementation into the server market.
It is true that currently the new revision chips will contain L2 cache, that I had not thought of when posting my previous response. However it is still correct due to the existence of the chips themselves.
Be aware that Core 2 Duo does contain an L3 ECC Memory Line if you were too look carefully, therefore L3 cache could have been implemented into Core 2 Duo if there was a need for it. Only ~512KB could have been implemented however due to the space on die.
Your second point:
|The voltage specifications for the Core 2s and Xeon 3000s are the same as well. Core 2 voltages = 0.8500 - 1.3625. Xeon 3000 voltages = 0.8500 - 1.3625. And they are both LGA775 (FC-LGA6). If anyone has gotten different voltage specs for either series please post them here
Core 2 Voltages = 0.8500v - 1.3500v (1.3625 is above rated, warranted, voltage specification). The voltages for the Xeon class equivalent processors are identical to their desktop variant.

However if we were to take these chips to a "very low" temperature.
Processor operating at -100C, operating as semi-conductor.
Take resistance to be negilable/extremely small.
Current physical properties suggest that the processor is capable of operating with high integer values (or non-equivalent) of voltage.
Approximated value would be 2.00v+ (Current [A] depending).
If you were to take a Xeon down to an equivalent thermal level you would notice it would operate with a higher voltage than a Conroe/Allendale
|There must be some differences between the Core 2 and Xeon 3000 chips though. I think in order for the Xeon 3000s to get a "Xeon" designation the instructions are probly a little different. That is that the instructions are meant to favor the demands of server operations. They're probly slightly better processors IMO. But it's not like you're going to get a Tulsa or anything.
As previously mentioned there are slight differences
