It would definitely be a different set of tests. Understanding what the GPU can do in the game is valuable, but understanding real-world use is also valuable. Most gamers I know are, at a minimum, running discord and one or two other applications while gaming.That‘s something many of us would have liked to see ever since 8C Ryzen 1000 were released and AMD consistently had a core count advantage.
Not sure how reviewers could start including this in their reviews with a straight face now. That said, I would welcome this and reviewers should also run these tests on older gen processors.
