Nvidia has discontinued production of GPUs based on the Turing architecture. The last GPUs include the GTX 1660, 1650, and 1630 series. Once the remaining inventory is sold, they will be gone, as will the "GTX" brand itself, and all Nvidia gaming graphics cards will be "RTX" models. There is one exception, however.

The GTX brand was first used in 2008 as a suffix for the Geforce 9800 GTX. It was later changed to a prefix for some high-end GPUs in the Geforce 200 series in 2008, such as the Geforce GTX 280.

Over the next few generations, the GTX prefix expanded to cover most series. However, not all models earned the "GTX" moniker until the GeForce 10 series in 2016, when the Geforce GT 1010 and Geforce GT 1030 were deemed unworthy of the final "X."

With the introduction of the RTX 20 series in late 2018 and Nvidia beginning to invest heavily in all ray tracing, GTX hit a wall. However, the GTX brand and pure raster GPUs got a reprieve with the GTX 16 series, which became a more value-oriented mainstream GPU line, culminating in the GTX 1660 Ti, launched in 2019.

At the time, it offered a welcome low-cost alternative to Nvidia's expensive RTX 20 series cards, but was definitely a disappointment in terms of pure raster performance in the name of bringing new hardware ray tracing acceleration to market for the first time.

Since then, production and sales have continued. However, according to Videocardz, production of the GTX 16 line has now ceased, and once the existing inventory of cards is sold, the GTX 16 and the GTX brand will be finished.

In a slightly odd twist of fate, the "GT" brand may live on past the demise of GTX. Currently, several Geforce GT 1030 cards remain for sale, and it is unclear if they will be EOLed along with the GTX 16 boards.

At any rate, while this information is not official from Nvidia itself, it seems likely that GTX is dead, long live RTX, and whatever comes after. NTX for neural graphics processing, anyone?
