32Mb may mean the total amount of memory that can be mapped at once in the graphics TLB .... Main cpu usage of TLBs is likely very different from graphics usage (which is pulling all the data for a frame 60 times a second) ... For some workloads 32Mb might be tiny and result in the TLB thrashing
I suspect it’s 32MB of coverage, which would be 2,000 entries which is a typical TLB size these days. Although then what’s he talking about the tile buffer?
2000 is probably the L2 TLB size, L1 TLBs are usually in the order of 10s of entries (but as I pointed out the decisions you make for graphics engines are very different from those you make for CPUs)
