New High Quality GPU Compression Codec Going Open-Source In The Coming Days

Wait, what? This doesn't make sense. Compression helps when you're bandwidth constrained. So if a faster PCI-E does not result in much performance improvement, then bus bandwidth is not a bottleneck. If bus bandwidth isn't a bottleneck, then why would one vendor's (Nvidia) compression produce a different performance result than a different vendor's (AMD) compression? This does not compute.

When you compress the memory you:

Increase the effective speed of the memory by transferring more at a time
Increase the effective useable memory since a decrease in size means more data can be put through the same bottleneck
