A TomsHW elképzelhetőnek tartja,
hogy az RDNA4 a 192MB Infinity Cache-el kompenzálni tudja a GDDR6 lassúságát.

"It could make sense for AMD to focus on enhancing its Infinity Cache design with RDNA 4, rather than moving to newer GDDR7 memory designs. There were rumors that AMD was investigating the potential for stacking an extra 16MB of L3 cache on each of its MCDs (Memory Cache Dies) with RDNA 3, and while that never happened with RX 7000-series parts, that doesn't mean it won't happen on RDNA 4. With potentially 192MB of Infinity Cache on a 384-bit interface with six MCDs, effective bandwidth might be high enough to compete with the upcoming Nvidia Blackwell RTX 50-series GPUs while sticking with GDDR6 yet again."
