The base RTX 3070 Ti card has only 8GB of memory.
Formerly one of the best graphics cards, the GeForce RTX 3070 Ti has a long-lost sibling that never made its market debut. The GeForce RTX 3070 Ti 16GB, which has been spotted in multiple EEC listings, appears to be real or has existed for some time.
MEGAsizeGPU (opens in new tab) leaked images and a GPU-Z screenshot of what appears to be an unreleased GeForce RTX 3070 Ti 16GB. However, it is a little confusing. Images of a GeForce RTX 3070 Founders Edition are displayed. The design and model name on the backplate support this conclusion.
However, the GPU-Z screenshot reveals that the GeForce RTX 3070 Ti has 16GB of GDDR6 memory as opposed to 8 GB. We suspect that a manufacturer recycled the GeForce RTX 3070 cooler for this GeForce RTX 3070 Ti 16GB based on its appearance. However, we’ve already seen user mods that double the GeForce RTX 3070’s memory capacity, so we wouldn’t be surprised if this GeForce RTX 3070 Ti 16GB is a garage-based laboratory experiment.
The GeForce RTX 3070 Ti 16GB is based on the same GA104 (Ampere) chip as the standard GeForce RTX 3070 Ti. It is still equipped with 6,144 CUDA cores, 192 Tensor cores, and 48 RT cores. However, the clock speeds appear to be distinct. While the GeForce RTX 3070 Ti has a base clock of 1,575 MHz and a boost clock of 1,770 MHz, the never-before-seen 16GB variant has a base clock of 1,590 MHz and a boost clock of 1,800 MHz.
The GeForce RTX 3070 Ti 16GB has double the memory of the original GeForce RTX 3070 Ti, as the name suggests. According to the GPU-Z screenshot that was leaked, the memory modules are different. We believed that the GeForce RTX 3070 Ti 16GB would utilize the same GDDR6X memory modules as the base model. Nevertheless, the GPU-Z screenshot indicates otherwise. Instead, the 16GB model is said to utilize significantly slower GDDR6 memory modules.
Memory bandwidth of up to 608 Gbps is provided by the GeForce RTX 3070 Ti’s 19 Gbps GDDR6X memory modules communicating over a 256-bit interface. According to reports, the GeForce RTX 3070 Ti 16GB has 16 Gbps GDDR6 memory modules. However, because it retains the 256-bit memory bus, the graphics card’s memory bandwidth is limited to 512 Gbps.
While the GeForce RTX 3070 Ti 16GB has slightly faster clock speeds and twice as much memory as the 8GB model, the Ampere graphics card has a lower memory bandwidth. Unfortunately, benchmarks for the GeForce RTX 3070 Ti 16GB have never been leaked, so its performance remains unknown.
