With the two Radeon RX 7900 graphics card models, the new GPU upper class from Nvidia and AMD has finally been complete since yesterday and should actually be readily available, but one day after AMD's launch there are obviously still some problems.
First of all, there is availability. While Nvidia's most direct (but more expensive) competitor (RTX 4080) is basically readily available, the availability of the new AMD cards is poor. Like in the best crypto times, most of the interesting models were sold out within minutes yesterday - and this despite AMD leaking in advance that enough stock should end up at the dealers.
According to rumours, however, it was not a surprisingly high demand that drastically limited availability, but the dealers simply had fewer cards in their warehouses than expected. However, it is also whispered that the supply is only slightly delayed and that better availability can be expected in the coming days and weeks.
However, those who don't want to gamble with a current GPU as a Christmas present are now more likely to turn to Nvidia. But wait and see might be the better choice, because at the beginning of next year we will be offered much cheaper mid-range models from both manufacturers, which will also have a much better price/performance ratio.
Until then, AMD can also fine-tune its drivers, which do not quite reach the reported performance. But perhaps this is also due to the lack of power. Because the AMD reference design comes "only" with 2 x 8 pin PCI power connectors, which is admittedly very honest in terms of energy savings. The models of the board partners, however, seem to swallow more energy with 3 x 8 pin, but also convert this into additional performance, which brings the XTX model in particular even closer to an RTX 4090.
In short, those who are not in a hurry should perhaps wait a few more months until the smoke has settled and one can also expect better availability and lower prices. And by then you should be able to see where AMD's new GPU generation ranks in terms of performance.
