Except their GPUs wouldn't be at 100% power all the time. Most of that time will be with programming, texture artistry, planning mechanics etc. I have a feeling that "back of the napkin" calculation is incredibly inaccurate.
A gaming PC uses more than 750 watts. Plus there's AC cooling for that which doubles the total power usage. So 750 watts includes not using the CPU all the time. Then there's the testers on the development team which greatly outnumber the coders. Testers are using the GPU the entire time they're working.
Lastly the cost comparison of the Rockstar developing GTA5 vs OpenAI training ChatGPT includes all the energy costs because they had to pay for everything. OpenAI is 2k developers compared to Rockstar 4k so it's not just salaries that make up the difference.
No, a gaming pc 'can' use 750 watts. But it won't be using 750 watts 100% of the time.
Power supplies only draw what they need, not their full rated capacity.
GPU's also downclock and lower their power draw when they aren't being stressed to their limits.
Lunch breaks cut 30-60 minutes out of those 8 hours.
And that article estimated 5000 employees internationally, which includes management, marketing, programmers, visual artists, musicians, sound engineers, voice actors, qa, translators, external consultants/contractors, and many more.
These are all people who have helped make the game at some point, and does not mean these people were in-office or employed for the entire development process.
Very few of those roles require top-end machines, and even fewer require their systems to be running at full speed 100% of the time.
Even if we ignore that that gaming companies have a larger energy footprint, it's still less energy. Let's assume its a regular corporation with only accountants and laptops:
6k employees 20 kwatt hours per square foot https://esource.bizenergyadvisor.com/article/large-offices 150 square feet per employee https://unspot.com/blog/how-much-office-space-do-we-need-per-employee/#%3A%7E%3Atext=The+needed+workspace+may+vary+in+accordance
18,000,000,000 watt hours
vs
10,000,000,000 watt hours for ChatGPT training
