GeForce RTX 5070 SUPER specs leak, faster and 18GB of VRAM

NVIDIA launched the GeForce RTX 5070 earlier this year, with the popular mid-range successor to the RTX 4070 delivering around 20% faster performance at 1440p. While the arrival of DLSS 4 helps unlock a new level of performance and image fidelity for the RTX 5070, our initial review highlighted two main criticisms: the 12GB of GDDR7 capacity and the fact that raw performance was only slightly better than the GeForce RTX 4070 SUPER refresh from 2024.

Well, it seems that we're going to be getting a GeForce RTX 5070 SUPER at some point in the future (rumors are pointing to an early 2026 release). The latest leak comes from the renowned insider @kopite7kimi, who has posted specs for the upcoming GPU on social media, detailing the upgrades over the baseline GeForce RTX 5070.

First up, the big difference is that the GeForce RTX 5070 SUPER is set to receive a massive 50% increase in VRAM capacity, featuring 18GB of fast GDDR7 memory on a 192-bit bus. According to reports, NVIDIA is now able to cram more VRAM onto its SUPER series refresh for the GeForce RTX 50 Series thanks to the arrival of 3GB memory modules.

This additional VRAM will make the RTX 5070 better suited for 4K gaming and demanding workloads that require 16GB of VRAM, such as running complex AI models. The upgrades don't stop there, as the GeForce RTX 5070 SUPER is also set to ship with 4.1% more CUDA, Tensor, and RT Cores than the baseline RTX 5070, alongside seeing its power draw increase by 10% to 275W. This suggests that we may also see higher Boost Clock speeds to deliver additional performance beyond the spec increase.

The GeForce RTX 50 Series has so far been an impressive generation for overclocking both the GPU and memory, achieving a stable 3+ GHz. Therefore, an RTX 5070 SUPER that is at least 10% faster than the baseline RTX 5070 for 1440p and 4K gaming is likely on the cards.

Here's a look at the preliminary specs for the GeForce RTX 5070 SUPER and RTX 5070 Ti SUPER (which have also leaked).
