In the last week or so the stock of Radeon cards has improved substantially. Reversals in mining have resulted in a short term reduction in demand but prices for video cards are still 50%-100% above MSRP. Most of the Radeon 6000 series cards are the recent RX 6700 Xt cards which are all above $1000 Canadian at NewEgg. The MSRP is far lower suggesting NewEgg is unable to get supplies from manufacturers but rather they are find stick from brokers.
GeForce cards are still not as well stocked. Prices are variable depending on the model of card. The RTX 3080 Ti is available but the older RTX 3080 is not available.
GDDR6X is undesirable for mining suggesting selective preferences for Radeon cards. Most mining forms suggest downclocking the VRAM to keep the heat under control. At present only NVIDIA is using GDDR6 while AMD is only using the GDDR6 standard memory chips.
Low prices for mining suggest more are abandoning the field as profits dry up. Back in 2007 when the last downturn happened saw a flood of video cards flood the market. Today that trend has reversed and cards are now back mining.
More Ryzen 5000 processors are available with lower prices suggest a CPU upgrade may have some advantages. The existing R5 3600 however has not been a problem.
The prospect for a modernized graphics card does not seem to be on the radar but the fall may have some new hardware but expectations are more for new games than new hardware.
The advantage for the NVIDIA resizable memory interface is of big advantage for gaming but it’s useless for mining. The idea of the resizable memory was to allow game assets such as shaders and meshes to be more quickly copied to the GPU to speed up game loading.
AMD has also designed a similar resizeable memory solution. Both AMD and NVIDIA want to improve the gaming experience which is what the competition is for. RX 6000 cards and RTX 3000 cards both support resizable memory with X570 and B550 based motherboards and apparently some older motherboards are also now supporting it.
