Absolutely TERRIBLE assumptions. Even games don't scale with more cores beyond a certain point. There is quite a bit of evidence that indicates that bandwidth is NOT an issue. Lack of VRAM can be. Poorly optimized games/game engines CAN be. You'd have to show me an actual test that shows bandwidth usage for me to believe that. I've worked extensively with OpenGL and DX3-11 along with some DX12 and Vulkan stuff, and I know what I saw writing code. All of my work was done in native C or C++ btw, no engines involved.
What you quoted is enough proof.
Despite having 42% more Cuda cores and much higher TDP than RTX 4060, It
was has only 26% higher performance at 1440p(
TPU).
You can't say that this mediocre increase in performance is because of bad scaling by having more SM, that's not true at this SM count.
I can back It up by comparing 4060Ti 16GB vs 4070 12GB -> 32% higher performance at 1440p while having 35% more SM.

And Vram was not an issue, because at average 4060Ti 16GB vs 4060Ti 8GB saw only 1% difference in performance at that resolution.
So the only thing left is BW bottleneck and If you check the specs, It's only a bit better 4060: 24MB L2 + 128-bit 17Gbit vs 4060Ti: 32MB L2 + 128-bit 18Gbit.
NVIDIAs *90 series is faster, sure, but look at the power budget and increased VRAM.
RTX 5060Ti 16GB has the same amount of Vram and power budged did increase, but only by 15W vs 4060Ti 16GB.
And 9060XT 16GB likely will have very high TDP, If the boost of 3230MHz turns out to be true. Wouldn't be surprised If It was higher than 5060Ti's 180W.
But with that boost, It could be really close to 5060Ti at least in raster.
I'm willing to bet (admittedly with no evidence other than profiling code) that games would see far more improvements with faster clocks over wider cores. AMD seems to be proving that so far. We'll see what happens long term.
Honestly, I don't care. I wasn't even talking about which method provides better scaling. I was pointing out that 4060TI is BW starved, so 5060Ti could have additional gains by using GDDR7.
