Nvidia announced their new 4090, 4080 and 4080 cutdown models. The pricing remains very high. The 4080 cutdown 12MB version is particularly highly priced that is why it is called a 4080 because it is obviously a 4070 but even Nvidia are embarrassed that a $600 price uplift on a mainstream model so they called it 4080 12MB.
As ever Nvidia present their product in a slightly dishonest best light. They seem very proud of DLSS 3.0. Commentators are suspicious that they mostly showed examples of games moving in a straight line. Cars along a road, planes in Flight Simulator. It is suspected it may be less clever in more complex situations. DLSS 3.0 also has the problem it only works on the new cards. Games companies, except those making a Nvidia sponsored game will not be interested. AMD FSR 2.0 from AMD while good but not quite as good as DLSS 2.0 works on the majority of graphics cards currently in use. Game developers like that.
We need to wait for 3rd party reviews before we form an opinion on there new cards. AMD make their announcement of new cards 3rd November.
