AMD Radeon RX 470 (4GB)

AMD's reference RX 470 launched as a 4GB card at $170 MSRP; some board partners also shipped an 8GB variant with the same 211 GB/s bandwidth, since only capacity differs. The machine behind the llama.cpp Vulkan figures in the source is the 4GB card, and no benchmark record is filed from it: at the source's own 512-token test length the weights alone (3.79 GB) plus a fp16 KV cache (0.27 GB) already exceed the card's 4 GB before any backend overhead, so the run cannot be represented honestly without misstating either the context length or the overhead. eBay used listings span roughly $15-110 depending on condition; $39 is the tracked average for a card discontinued in 2016. Any 'new' listing is new-old-stock rather than a real retail channel, so new is left empty rather than carrying the unobtainable 2016 launch MSRP.
