Always a good giggle listening to people complain about bus width who clearly have no clue what a bus is and what its bit width does,. but are sure that Smaller Number Bad so Nvidia Bad.
Remember the GTX 970 RMADAC partitioning 'issue', that was so much of a major issue that nobody even noticed it existed for a good year after the card launched, was extensively independently benchmarked, and remained the price/performance peak for its generation? The internet hate machine got a good rager on for that, with complete lack of understanding of what was actually going on not being any impediment - the card was not 'missing' 500mb, it just had a single RAMDAC channel that was unidirectional and not bidirectional, with driver-side memory readdressing to avoid it having any practical performance impact (the whole reason GPUs use GDDR rather than DDR after all is because they perform mostly large file reads, occasional large file writes, and basically no small file random access).
As always: buy components based on actual benchmarked performance, not specsheets or branding. If it offers adequate performance at a price you're willing to pay, then great, if it doesn't don't buy it. Giving a pair of foetid dingo's kidneys whether e.g. the sticker on the side of the card says "4070Ti" or "4080" is ludicrous if the performance and price remain identical.
