New Turing dies set to put an end to the "two-tier" system for RTX cards

Reviewers and GPU aficionados have previously observed that there are two "classes" of the dies that make up NVIDIA RTX cards. They are essentially the TU10x-xxxA and TUx-xxx chips, the "A"s of which are approved for factory overclocking. However, new variants of the same dies negate this dichotomy.

Tech blogs and sites have been aware that NVIDIA's RTX cards are affected by a "class system" since these GPUs started hitting the market. This system stems from the existence of 2 variants of the same Turing (TU104 or TU106) chips.

For example, there is such a thing as a TU104-400-A1 chip - and also such a thing as a TU104-400A-A1 chip. The first "A" in this nomenclature is what differentiates the two. These variants tend to be found in higher-end products that can be overclocked, whereas the "non-As" are often in lower-end cards that are not rated for the same.

For example, the TU104-400-A1 chip was found to be incorporated in the basic ASUS RTX 2080 Turbo card, whereas the TU104-400A-A1 featured in its ROG Strix counterpart. Then again, this is not necessarily a hard and fast rule: a kind of OC-mode chip lottery is also possibly in effect when buying RTX cards thanks to this dichotomy.

A contributor to TomsHardware.de claims to have exclusive information on new variants of Turing GPUs. They are apparently to be called the TU104-410 & TU106-410 series of chips - and that's it: no "A-class" sub-variants here.

The correspondent (Igor Wallossek) also now projects that overclockability will be constant across these new series. Therefore, a shift to these new dies among manufacturers may render more effective and flexible RTX performance more affordable in the future.
