Nvidia GeForce RTX 3070 Founders Edition Review: Taking on Turing’s Best at $499

The Nvidia GeForce RTX 3070 Founders Edition is here — or at least it will be on October 29, and we can provide a full review today. Following in the footsteps of the GeForce RTX 3080 and GeForce RTX 3090, this is the third of the new Nvidia Ampere architecture GPUs. In terms of performance, price, and features, these new GPUs rank at the top of our GPU benchmarks hierarchy and are some of the best graphics cards right now. Except, they’re still almost impossible to find in stock. Will the RTX 3070 suffer the same fate at launch, and how does it stack up against the other current and previous-gen GPUs? That’s what we’re here to find out.

Fundamentally, the GeForce RTX 3070 will be similar in a lot of ways to the RTX 3080 and 3090 … except, not really, because changes to the core counts, memory capacity, and memory speed can all have a pretty significant impact on performance. Nvidia claimed during the Ampere reveal in September that the RTX 3070 was “faster than the RTX 2080 Ti,” which would be an impressive result if it’s true. It has more cores and higher TFLOPS ratings, but less memory and bandwidth. Here’s the block diagram for GA104 along with the full spec sheet for the Ampere GPUs, along with the RTX 2070 / 2070 Super that the newcomer replaces.
