RTX I/O is more efficient and takes barely a hit on your CPU cores. 0,5 cores is nothing and that's for 14gbps, which funny enough is pci-e 5.0. its also the reason i never cared for 4.0 after seeing it the slide. They are very much going to focus on pci-e 5.0 and a new series of gpu's that will be focused around it. the 3000's feels a bit like a old gen on steroids card, the v-ram kinda also helps with that vision.
Still even without this, asa u can see CPU cores can easily compress a nvme drive with 3,5gbps without effort. Sure it costs cpu cores, but what are you using those cpu cores for with load screens anyway? u can slam them all to 100%.
The reason why they don't do it, is because nobody even cares about loading speeds until sony moved forwards with it. The reason sony cares = because they are heavily relaying next gen on this shit.PC? not so sure about that. As i didn't hear anybody complain about loading speeds ever ( obviously game design could change entirely so yea there is that ofcourse) .
That is if directstorage is getting ignored largely on the PC platform. It could be a revolution or just more of the APU bullshit we heard last generation. We still have no proof how much that SSD in sony is actually doing and nobody seems to provide any insight on this because that sony SSD is most likely not doing very much at the end of the day. So this could also mean that rtx i/o will largely be a minor improvement at the end of the day. Could obviously be a big one if it gets used a lot.
We will see tho.
