It really depends on that games you play and what price range you’re looking at. In general it is around the same performance as a 3060. However, the intel cards have pretty good value at the low end. When it comes to cost per FPS, the A750 is pretty competitive at $200. Compared to a 4060 (which is a horribly priced card at $300), the A750 performs 16% less on average (according to LTT), yet costs 33% less. Also, the A380 is also one of the cheapest ways to get hardware AV1 encoding in your system.

No.

Short answer is no. Long answer is no. The problem is their drivers (and hardware) are very young so there's a lot of odd things games can do that hurt performance in unexpected ways.

In practice they are not as good because Intel lacks experience, but I think they're on the right track. Is it worth the money today? Probably not. The risk of coming across a game that doesn't run well is just too high.

I really wanted Intel to be a serious contender for my last GPU purchase but there were too many good, consistently performing options in that price range for it to make a lot of sense.

Despite what others say here, I would say sort off...

Right now you get something which gives similar performance to AMD cards of the same price category, but with more compatibility issues. However, you might be willing to take the risk, as in theory the ARC hardware is significantly better than similar priced AMD hardware, just the drivers (neither on Windows or Linux) are not good enough to fully utilize it (well that or older games don't make use of the more modern architecture of the Intel GPUs).

Nvidia doesn't really compete right now as their hardware is just over-priced and without open-source drivers is pretty much a no-go on Linux anyway.
