As the suspected announcement of NVIDIA’s highly-anticipated Ampere RTX 3000-series GPUs on September 1st looms ever closer, new information suggests NVIDIA plans to reveal at least three high-end variants with a significant improvement when it comes to memory capacity.

According to leaker Wjm47196, NVIDIA will have 10 GB, 20 GB, and 24 GB variants in its Ampere line-up at launch. The leak suggests the GPUs will all feature a GA102 core with memory bus interfaces of either 320-bit or 384-bit. The GA104 core variants will reportedly feature a 256-bit bus interface and will ship with 8 GB.

All the Ampere GeForce RTX 3000-series GPUs will reportedly feature GDDR6X memory, although no DRAM manufacturers show any signs of producing the memory. We can’t discount NVIDIA requesting manufacturers keep quiet and not post the information on publicly available websites and the like to ensure the news makes a splash when it arrives in a few weeks. Either way, September 1st should put any speculation to bed.


As for which SKUs align with these specifications and memory configurations, the details remain sketchy. Nevertheless, VideoCardz has offered some estimates.

The RTX Titan could be the GA102-400 GPU, 5376 CUDA cores, 24 GB memory, 384-bit variant. The RTX 3090/3080Ti may have a GA102-300 GPU, 5248 cores, 20 GB memory, and a 320-bit memory bus interface. The RTX 3080 may point to a GA102-200 GPU, 4352 CUDA cores, 10 GB memory, and a 320-bit memory bus interface. On the lower end of the line-up, the RTX 3070 could include a GA104-400 GPU, 2944 CUDA cores, 8GB memory, and a 256-bit memory bus interface. Finally, the RTX 3060 could be a GA106-300 GPU, 6 GB memory, and a 192-bit memory bus interface.


The leak also suggests NVIDIA has plans to launch souped-up variants of the Ampere GeForce RTX 3000-series GPUs under the SUPER name in the year ahead with better specifications than the launch SKUs. Based on the SUPER line-up this gen, we are presumably going to see clock speeds go up, higher memory speeds, and improved memory capacity SKUs. As with the Turing SUPER cards, we could also see a price cut on the launch variants.

In other Ampere news, reports emerged earlier this week that alongside launch Founders Editions, would-be owners will be able to get their hands on a selection of third-party custom AIB variants day one. As it stands, it seems builders will be spoiled for choice.

As always, take all of this with a pinch of salt, especially as NVIDIA suspect big reveal is now only a matter of weeks away. In the meantime, check out our top recommended GPUs over here.
