[GTALUG] I asked ChatGPT to compare iGPUs.

[D. Hugh Redelmeier]

I have two models of dirt-cheap notebook.  One was $300 for an "open box" 
not quite two years ago and the other was $300 ten days ago.

It's easy to google on the web to compare the CPUs but not so easy to find 
out the difference between the integrated GPUs.  So I asked ChatGPT 3.5 
(the free one).

"compare igpu in i3-1005G1 and i3-1215U"

The answer looked OK but I'm quite sure that it is very wrong.  It thought 
that the i3-1005G1 was newer and more advanced than the i3-1215U.  The 
first clue is that it thinks that the i3-1215u is part of Intel's 8th gen 
Core processors whereas it is part of the 12th gen.

I then asked it "why do you thing i3-1215u is 8th gen?".  It appologized 
and said that that processor was part of the 10th gen "Comet Lake".  It is 
not.

I wonder if this is due to its training date being before the i3-1215u's 
launch (first quarter of 2022).

It sure would be nice if it knew what it didn't know.

Note: I'm not cherry-picking this example.  This is the first prompt I've 
given in weeks.

======== ChatGPT output:
When comparing the integrated graphics processing units (iGPUs) of the 
Intel Core i3-1005G1 and the i3-1215U, there are a few key differences to 
consider:

    Architecture:
        The i3-1005G1 is part of the 10th generation Intel Core 
processors, codenamed Ice Lake. It features the Gen11 graphics 
architecture.
        The i3-1215U, on the other hand, belongs to the 8th generation 
Intel Core processors, codenamed Kaby Lake Refresh. It features Intel HD 
Graphics 615.

    Performance:
        The i3-1005G1 generally offers better graphical performance 
compared to the i3-1215U due to the newer architecture and improved 
integrated graphics in the Ice Lake processors.
        The Gen11 graphics in the i3-1005G1 typically provide better 
support for modern gaming and multimedia applications compared to the 
Intel HD Graphics 615 in the i3-1215U.

    Features:
        The i3-1005G1 supports newer technologies such as Intel's Adaptive 
Sync, which helps reduce screen tearing during gaming or other 
graphic-intensive tasks.
        The i3-1215U may lack some of these newer features and 
optimizations found in the 10th generation processors.

    Power Efficiency:
        The i3-1005G1, being a part of the Ice Lake architecture, benefits 
from Intel's advancements in power efficiency, resulting in potentially 
better battery life and lower power consumption compared to the i3-1215U.

In summary, while both iGPUs serve their purpose for light gaming and 
everyday tasks, the i3-1005G1 generally offers better performance and more 
advanced features due to its newer architecture.

why do you thing i3-1215u is 8th gen?
ChatGPT

I apologize for the confusion. It seems there might have been a mistake in 
my response. The Intel Core i3-1215U is actually part of the 10th 
generation Intel Core processors, codenamed Comet Lake. Let me correct the 
comparison between the iGPUs of the i3-1005G1 (Ice Lake) and the i3-1215U 
(Comet Lake):

    Architecture:
        The i3-1005G1 features the Gen11 graphics architecture as part of 
the Ice Lake processors.
        The i3-1215U, being a part of the Comet Lake processors, features 
Intel UHD Graphics.

    Performance:
        The i3-1005G1 with Gen11 graphics generally offers better 
graphical performance compared to the i3-1215U with Intel UHD Graphics due 
to the architectural improvements in the Ice Lake processors.
        The Gen11 graphics typically provide better support for modern 
gaming and multimedia applications compared to Intel UHD Graphics.

    Features:
        The i3-1005G1 may support newer technologies and features compared 
to the i3-1215U, although both are part of the 10th generation Intel Core 
processors.

    Power Efficiency:
        The i3-1005G1 might have an advantage in power efficiency due to 
the architectural improvements in Ice Lake, potentially leading to better 
battery life compared to the i3-1215U.

So, to clarify, both the i3-1005G1 and the i3-1215U belong to the 10th 
generation Intel Core processors, but they differ in their graphics 
architecture and associated features.
