The absolute numbers don't seem far fetched. An AVX optimized memcpy on my high end machine (DDR4) has a throughput of 30GB/s. As long as they are using the same memcpy routine in both the decompression case and the 'only memcpy' case, that seems reasonable. Obviously, the quicker memcpy becomes, the faster the decompression has to become to maintain the same performance ratios, but things like faster clock speeds or multi-threading can make that issue moot.
