APOLOGIST FOR AMD

Reading a post on Hardware Times suggests mining is not a significant part of the AMD GPU market. This is nonsense as I have lots of real evidence that whole allocations of 500,000+ cards were sold to mining concerns. So the accusation of being an apologist is upheld by evidence.

Given the hard to find RDNA cards, RDNA 2 cards are very expensive selling at double to triple MSRP.

Now that 2022 is at hand AMD is mentioning RDNA 3 cards are next up. This chart is speculative but the sources are usually accurate. The RX 7900 XT suggests that it can play any game for at last a few years at 3840×2160 HDR10. The Navi 31 (RX 7900 XT) flagship will be based on an MCM (chiplet) design with a total of over 15 thousand cores (15,360 to be exact). It should easily be 2.2-2.5x faster than its predecessor, with the RX 7800 XT (Navi 33) beating the RX 6800 XT by 30-40%. RDNA 3 cards may well be delayed depending on the available foundry production.

NVIDIA was using Samsung to make logic but it’s unknown how many wafers a month that line is producing. Most likely the line is making maybe 20,000 wafers but realistically 50,000 to 100,000 wafers a month are needed.
