November 18, 20223 yr I think it is necessary to separate the results of a processor with EM64T support and without support for these technologies. There are several s478 processors with EM64T support and several motherboards based on "modern" chipsets, which will not allow you to achieve high results, but will allow you to formally pass some tests.

You are talking about socket 478 Are you sure about "several" ? I always thought it was a couple.
November 18, 20223 yr Author Yes, 478. It was 2, may be 3 processors. I have a 3.4GHz Prescott now and my results in 64 bit mode are higher than 32 bit ones. For example here - https://hwbot.org/submission/5124019_ I have Biostar on g31 with 478, asrock on 945 with 478 and some server boards. This result was on EM64T cpu too - https://hwbot.org/submission/4183403_mrgenius_cinebench___r20_pentium_4_3.4ghz_(prescott)_103_cb Also i have a 478 to 774 adapter, and I think this cpu should be splitted from regilar prescott-1m.
November 18, 20223 yr I would not split. Choosing the right CPU stepping and mainboard chipset is also part of the game. Same applied to unlockable AM2+/AM3 chips and no one ever complained. Edited November 18, 20223 yr by TaPaKaH

Not my call ... But to be honest there are numerous examples of Intel's own modified cpu's , and there is no need for a split. The most recent example is the Alder Lakes , where the first batches had the AVX512 instructions and the later not. They all compete into the same category. 2 hours ago, IdeaFix said: SL7Q8 (EM64T), SL7QB (EM64T), SL8JX (EM64T, NX/xD??) Now , for the history. SL8JX was never (to my knowledge) proven to have EM64T (G1 stepping and not a special production cpu) Furthermore Intel document 302352-033 did not noted them as EM64T capable. On the other hand SL7Q8 and SL7QB , both special and limited production for IBM are verified EM64T.

Only SL7QB and SL7Q8 are fully capable of running 64-bit OS. https://forums.mydigitallife.net/threads/running-win10-by-intel-s478-cpu-now-and-maybe-older-cpu-in-the-future.81451/page-5#post-1637849 Edited November 24, 20223 yr by Antinomy
