It is no secret that NVIDIA is also preparing a 20GB model of the GeForce RTX 3080 graphics card. It has been speculated for weeks now and we had no problems confirming this information with multiple sources. The internal roadmaps clearly state PG132 SKU 20 board design (RTX 3080 20GB) but the launch date has not yet been set.

Based on the information that we have the RTX 3080 20GB will arrive after AMD Radeon RX 6000 series. This model is simply a response to the Big Navi, the 16GB model, rumored to be Radeon RX 6900 XT. The date was not communicated to AIBs, simply because NVIDIA did not know when the Big Navi launches. This of course has changed, because AMD already announced RX 6000 series will be unveiled on October 28th. The RTX 3080 20GB might launch shortly after Radeon products will be available.

The latest development in RTX 3080 20GB news is the just-released document by NVIDIA. Yesterday NVIDIA released 8nm Ampere (GA102) whitepaper where the RTX 3080 model is listed as ‘GeForce RTX 3080 10GB’. Nowhere else in the document NVIDIA lists memory configuration with SKU name, clearly indicating that there are more versions coming.

The GeForce RTX 3070, which is also listed in this document, lacks memory configuration in the product name. This is despite rumors that we will be seeing a GA104-based 16GB model too. However, the explanation for this is rather simple. The 16GB model will feature a different GPU configuration. The card will likely adopt Ti or SUPER branding so it is a completely different SKU. We have been told that this model will launch after both RTX 3060 Ti and RTX 3080 20GB.

NVIDIA GeForce RTX 3080 officially launches today and in just a few hours you will be able to purchase one. However, do not be disappointed if you won’t be able to find one in stock. In a few weeks (~2 months) you will be hearing a lot more about the RTX 3080 20GB. The 10GB model may not look like the best offer at that time.
