Some probing / (micro)benchmarking and commentary of the A770 by the folks at Chips and Cheese.
Intel’s Arc GPUs represent the company’s third attempt at taking on the dedicated GPU market.

Someone was saying the issue with performance in games like CS: Go seems like it's due to lack of parallelism. The micro-level benchmarks done by chips and cheese reflect that. In that particular instance the A770 was on the level of A380.
-Higher execution unit latency
-Low memory controller and cache performance, and bad at hiding them
-Difficulty scaling memory bandwidth with threads, yet it especially needs it to make up for above mentioned deficiencies.
So how much can be solved by software and how much by hardware? They also mention part of the problem is due to the "iGPU" mentality.
Some of the aspects are not just a generation behind, but two, three, or four generations behind. Some micro level tests put it on par with AMD's Terascale 2 GPU!
