Hello, I love this old thread, it's like a great time capsule for such a long running game.
I got 12.62 seconds/turn on the Dell XPS 15 laptop, which is almost exactly two years old.
Processor Intel(R) Core(TM) i7-9750H CPU @ 2.60GHz 2.59 GHz
Installed RAM 32.0 GB (31.7 GB usable)
System type 64-bit operating system, x64-based processor
3840 x 2860 display
Hang on...when I test the GS AI specifically (not the base-game AI) I clock at a whopping 117.23 seconds/turn, but this was on an enormous map stuffed with 14 civs. Is this the same for everyone? I know a laptop won't compete with a tower setup.
I recently was trying out civ on a laptop, and got similarly terrible results, with a few notes for improvement.
The laptop is a HP elitebook 840 G6 with a I7-8665U. Intel integrated GPU. So a business laptop not meant for gaming.
First run with no tuning: Base AI = 13.21sec, GS AI 120.46sec
Second run, after installing a second 16GB of RAM for dual channel: Base AI = 12.76sec, GS AI 111.16sec
At this point I noticed (using hwinfo software) that the laptop was throttling the CPU hard on electricity, only 12W on an extended run. I used the throttlestop program and bumped that up to a PL1 of 20W.
Third run with 20W: Base AI 11.27sec, GS AI 89.18sec
Fourth run, bumped to 25W: (didn't try base AI), GS AI 77.23 sec
TLDR power limits were slowing down my laptops. If you can boost the power limits (with intel XTU or throttlestop) then it can help. Then you probably bump into thermal limits. So still pretty bad, but better. i think there were also differences if I ran on battery or not. (these tests were AC power)
Contrast with my other laptop, a cheap Motile laptop with Ryzen 3500U (on battery, even):
Base AI 9.75sec , GS AI 98.88sec
(the laptop fan does whine like a banshee though) Also, I noticed during the GS AI benchmark that the graphical frame rate was so slow that the "timer" in the top of wasn't even able to keep up with real time. In other words one tick of the benchmarks clock took about 2 real life seconds during the initial intense parts.
In contrast with my old desktop, which is a Ryzen 1600AF moderately overclocked to 3.9ghz, ample CPU cooler, and a Radeon RX 580.
Base AI 8.46sec, GS AI 44.84sec
