Yes, being able to load GPU formatted data directly into GPU memory from an SSD is a Big Deal. The only quibble I have with @TimSweeneyEpic 's quote is that you can bypass kernel buffers on PC with unbuffered IO. The GPU driver overhead still dominates. https://t.co/lEsdyG8kLY

The plot thickens.

Almost none of that tweet makes sense to me. All I get is SSD = big deal. Everything else flies over my head.

For the average person, that is pretty much what it sums up as. SSD = Good. HDD = Bad.

I have some ideas, but that side of tech isn't my thing. I'm better with the details of graphics hardware (such as TMUs, Bus Interface, and CUDA). What can be deduced though is the pipeline is changing and much of the work is going to be offloaded to the SSD (in NVMe form). This is why some people mistakenly expect the consoles to 'beat' the PC next gen, while not understanding that the PC can already do that, and when it is provided with those types of SSDs in the market, will actually do it better.

AMD's RDNA 7nm processors can't even outperform Nvidia's 12nm Turing line which is like 2 years old architecture now. 

Nvidia Ampere 30-series is going to wipe the floor with AMD, lets be honest. 

AMD is doing wonderful things on the CPU side versus Intel mostly in terms of offering nice performance for cost solutions, but on the GPU side they don't match up very well versus Nvidia. 

Correct. RDNA does come up short against Turing.

But there are edge cases where RDNA will out-edge nVidia, AMD's main dominance since Graphics Core Next debuted has been asynchronous compute and RDNA still does really well there... Not as well as Vega, but still really well, when AMD's OpenCL compiler isn't being shit that is.

Pretty much, yeah. I'm sure the debate will rage on for years to come; might even get interesting when we have actual games to go on. Now we've seen what PS5 can do the ball is really in Microsoft's court to show a similarly impressive example of what XSX can do.

Once the next-gen games start rolling out and we can dissect the real-world implicated differences in actual games (What these devices are meant for!) then we will have an idea between platform differences.

Keen to see what the Xbox Series X can do, Microsoft needs to demonstrate that appropriately.
