Huh, so, coming in just behind the 1650 GDDR5 version.
Well, I will say this: if these benchmarks are representative of real world gaming performance, then this is, technically, a better card than the 6500XT.
30% lower performance, but 50% lower power consumption, makes it a more efficient card.
And, let's be honest, there's still a market for the GT 1030 GDDR5, isn't there? This outperforms it. Hell, Nvidia decided that there was a market for the GT 1030 DDR4 variant.
There's also still a market for those 1650 GDDR5 cards that are still around, so there's a market for this, particularly given that, a smidgen less performance than the 1650 GDDR5, but with about 30% less power consumption.
Sure, it's weaksauce overall, but still better than any iGPU, even the Ryzen 5x00G APUs. There's a niche for it, if it's inexpensive enough.
EDIT: what would I have changed? I'd have called the RX 6500 XT the RX 6400.. and the RX 6400 I'd have called the RX 6300.
