TPU article on unlocking the 9070
Of note:
"...More importantly, the flashed RX 9070 was found to offer significantly improved overclocking headroom, and PCGH was able to tune up performance by 15-20% over stock RX 9070,
bringing its performance to match a stock RX 9070 XT, which was
confirmed by a set of 3DMark benchmarks."
Regarding the other bit, yeah. I think we're on the same page about it being a limiter, but not a promoter of FPS. That said, this has been the Nvidia line in the sand for about a decade now. September 2014 was when the 970 launched. Despite this, they've always been proven to be full of crap when their cards eventually become VRAM choked. I'm pretty OK then that this was largely a circular logic loop about VRAM, so thumbs up on comprehension from my side.
There are no issues. There is only opportunity and the targets of the sprint.
And the bile raises in my throat saying that, with the desire to pimp-slap myself for saying it.
