Last May there was basically more GPUs that went online during the entire combined Litecoin mining days back in late 2013 early 2014.
Back then it was estimated that about 320,000 GPUs were actively mining.
Last May there was only 350,000 GPUs being added monthly.
Now things have basically risen exponentially.
Last month about 2.1 million GPUs were added to the ETH network. About a 6-7x increase.
So basically more GPUs are added every 5 days than the entire Litecoin GPUs in circulation of 2014
More GPUs are added every 15 days than the entire ETH GPUs in circulation when I created this thread back last May.
During the Litecoin days, all AMD GPUs were sold out.
Last Summer all AMD and Nvidia were sold out
Now the capacity has risen exponentially so I am guessing that AMD and Nvidia somehow have increased production in the last year or so. Because too many GPUs are coming online .
I never had an issue buying AMD GPUs during the Litecoin mining days - with NO "limit 1" restrictions ANYWHERE.
I do remember a few reports of specific retailers being out on occasion of specific GPU model cards - usually the 7870.
Nvidia seems to be in major shortage due to a combination of TSMC switching Pascal GPU production over to Volta production "around the end of the year", and a VERY good Christmas sales season.
AMD - partly the Christmas sales season, partly mining demand.
Last SUMMER the supply of GPUS gradually IMPROVED, it was last SPRING that it got really bad for a while with AMD cards pushing into Nvidia 1070 range and even low-end 1080 range, and A FEW Nvidia models having severe supply issues for less than a month and some mild price gouging.
That has NOT happened this time around - though it's been close - and Nvidia is who ran out FIRST.
