One has a Celeron 4205U 1.80Ghz dual-core (2C/2T), for $209.

The other, has a Pentium Gold 5405U 2.30Ghz dual-core w/HT (2C/4T), for $269.

Both have 4GB RAM (soldered), 128GB SSD (M.2 SATA), and Win10 Home (non-S-Mode, as far as I can tell).
The Celeron is a 15.6", the Pentium Gold is a 14", which would be preferable. Both are 1366x768, and unlike AMD, I don't believe that Intel allows user-settable "virtual resolutions". (Although, I wish that they would.)
I wasn't able to find the 4205U on www.cpubenchmark.net , it doesn't appear to have any entries yet. Hence my dilemma. The price is nearly 22% higher, but what is the difference in performance? And how much does HT gain on a modern Intel Core architecture (which hasn't changed notably since Skylake)? I know that SMT makes a pretty decent difference on Ryzen, especially 3rd-Gen.
Here's a site with Passmark numbers for the 4205U, seems a 28% difference in performance?
Interestingly, it shows that the Celeron is Optane-enabled, whereas the Pentium is not, and the Pentium has AVX extensions, whereas the Celeron is unspecified.

Maybe I should pay the difference, just to make certain that the CPU has the AVX support, in case future applications depend on it? (*Not really all that unlikely.)
Hmm, this comparison shows that the 5405U does NOT have AVX. Or at least, doesn't list it.

8GB RAM, 128GB SSD, i3-8145U, for $289.

Here's the ARK listing for the Pentium Gold 5405U, shows NO AVX/AVX2! That's a no-go then.
