None.
The 480 was pretty much a respin of the 380, which then evolved in the 580 and finally the 590.
The higher card closest in time would be Vega 56/64 but not sure it's countable as same gen.
The RX580/RX590 were the respins of the RX480.
The RTX480 was more or less targeting R9 290/R9 290X/R9 390/R9 390X performance from launch:
It was pretty close to the R9 290X/R9 390X,and the R9 390X wasn't that much slower than a GTX980 either:
So basically it was pretty much the performance of the previous generation AMD 2nd tier/3rd tier dGPU(or close to the second tier Nvidia dGPU as the AMD Fury non-X was faster than a GTX980).
Also,it was quite clear the RX480 could have been faster too. Due to WSA,AMD was forced to use Global Foundries 14NM,instead of TSMC 14NM. If Polaris had been made on TSMC 14NM,it would have probably clocked higher. The RX590 made on Global Foundries 12NM could barely hit 1.6GHZ overclocked,whereas the earlier GTX1060 could hit over 1.7GHZ when overclocked.
This is where all the "Beast Mode" RX480 rumours came from I suspect,as they implied Fury non-X matching performance. The RX590 matched a Fury non-X which was the second fastest AMD dGPU of the previous generation on an improved Global Foundries 14NM type process node. I suspect the RX480 was meant to clock higher initially but Global Foundries 14NM sucked. Hence why the stock RX480 cooler was inadequate and the card drew a bit too much power from the PCI-E main connector.
AMD probably missed their performance targets for the RX480.
So to put in context a modern Polaris would have been matching the 2nd or third fastest AMD dGPUs of the previous generations. So if we say the RX6900 and RX6950XT are functionally the same,it would be the RX6800 or RX6800XT with a relatively big framebuffer for the time.
The RX480 8GB was $239. That would be $302 in 2023. So with VAT,that would be £290.
Then merely three years later,the RX5600XT/RX5700 essentially doubled performance over an RX480:
The RX5600XT/RX5700 matched or even exceeded the performance of the Vega 64 based dGPUs which were the second fastest AMD dGPU of that generation. This was with AMD upselling the RX480 replacement as the RX5700XT(originally it was called the RX690). Even with inflation it would price the RX5600XT just over £300. But there were offers for the RX5700 reference model for less than the RX5600XT. The RX5700XT was almost the same performance as the Vega VII for nearly half the price. These dGPUs used a cutting edge TSMC 7NM process node and relatively new GDDR6.
So even if we add inflation into all of this,where are we seeing dGPUs around the £300 mark,with RX6800/RX6800XT level performance and 16GB of VRAM from either AMD or Nvidia?
We are not. People are accepting abnormal combined Pandemic and Mining pricing as the new normal. This is with things such as GDDR6,etc prices going down a lot compared to back then.
