It’s not called a discount when you get a lower tier product
They will never voluntarily lower the price of something. They will keep the price the same as long as people continue buying them.
Is there a significant impact on performance? It’s entirely possible that the RAM was overspecced before.
It’s not worse if it doesn’t perform any differently. Besides, you don’t actually know the BOM cost.
If it was overspecced before, then that means it was using parts more expensive than it needed to. Nobody makes RAM that is slower and also more expensive for the same capacity. Logically, this should translate to lowered prices for the GPUs using the cheaper parts.
It’s objectively worse. “Real world performance” might be the same, but I’m paying for performance AND parts.
