I don't know if it was meant as a literal comparison of SKUs with a typo, or just a hypothetical question, but there is no Core 1005H from Intel that I am aware of. There are similar SKUs but not that exact one. What Intel has made are the following:
Celeron 1005M (Ivy Bridge)
Core i3-1005G1 (Ice Lake)
Core i5-10500H (Comet Lake)
Lets go with the assumption of a hypothetical CPU with the new naming. If so, then these are the two chips he is mentioning are:
A) Intel Core ? processor 1005H
B) Intel Core Ultra 7 processor 155H
These names are made up of four parts that I'll color code.
A) Intel Core
? processor
1005H
B) Intel Core
Ultra 7 processor
155H
The
purple indicates the chip marketing level--Is it premium or mainstream. Unfortunately, the truncated name given to us doesn't indicate the tier (formerly i3, i5, i7, i9), so I left it as a question mark. But, I'll assume that since chip A is so advanced (see the paragraph below) that even a low tier is better than the
Ultra 7 of chip B.
The CPU generation is the first two digits in
red (although if the first digit is 0 it is not used). Thus:
Chip A is the
10th generation (starting with Meteor Lake being generation
1)
Chip B is the
1st generation (Meteor Lake)
That would make chip A far more advanced for the CPU.
Intel hasn't mentioned what the last two digits in
green will be exactly. But I would assume the
05 is low end graphics for the 10th generation and
55 is mid-level graphics for Meteor Lake. I'm going to assume that by the time we get 9 more generations, chip A will still have a more powerful GPU than chip B even though it is a low level for the 10th generation.
Finally, the power level in
blue,
H, is the same for both chips.
Thus, with the insufficient information given to us, I'll go with chip A as being far superior as it is 9 generations newer.
