These's some rumours going around about a 128MB Infinity Cache.
I'd say its very likely to be correct, a patent was published today from AMD called 'ADAPTIVE CACHE RECONFIGURATION VIA CLUSTERING', link here here:

Basically, what I think it will allow, is greater L1 cache capacity for GPUs. It does this by dynamically creating 'a plurality of compute units' clusters. The dynamically created clusters allow a 'backup' pool of shared L1 cache to be accessed, if the L1 cache for a CU (Compute Unit) isn't sufficient.
L1 cache is the fastest (lowest latency) type of GPU cache. So the more L1 capacity, the less the slower L2 and L3 caches are used.
My thoughts - The 5700 XT uses 128KB L1 Cache per Graphics Engine (4 in total). Maybe L1 cache sizes would also need to be increased? The RTX 3080 has a total of 8.7MB of L1 cache (128 KB per SM), quite a bit higher.
