This page shows quite a bit of discrepancy between the RX 4XX and RX 5XX results.
The reviewer mentions the following:
The optimizations seems to have been applied only to the RX 500 and Vega series (for now).
Is that the case? From what I understand, RX 4XX and RX 5XX are basically the same product, but only the newer one got the optimization treatment.
Are RX 4XX owners being left behind artificially?
Some official feedback from AMD would be nice.
Thanks for your time.
