Introduction

NVIDIA stirred up the graphics card market last week with the debut of its GeForce RTX Super family of graphics cards that increase performance at existing price points in a bid to preempt AMD's Radeon RX 5700-series "Navi" graphics cards. The first two of three RTX Super-series SKUs are the RTX 2060 Super and the RTX 2070 Super. NVIDIA displaced the RTX 2070 from its $499 price point with the better-endowed RTX 2070 Super as AMD beat the RTX 2070 at $399.

The most interesting aspect about the RTX 2070 Super is that it's based on the 13.6 billion-transistor "TU104" silicon since NVIDIA had maxed out the "TU106" with the original RTX 2070. The "TU104" is at the heart of the much pricier RTX 2080 and upcoming RTX 2080 Super graphics cards. What this means to consumers is that most custom-design add-in card (AIC) partners would rather reuse their existing RTX 2080 board designs with a little cost-cutting on the VRM instead of spending money on developing and validating new PCBs. Another benefit is partners using heavy cooling solutions that were originally designed to handle the much hotter RTX 2080, and perhaps even the RTX 2080 Ti.



NVIDIA carved the RTX 2070 Super out of the "TU104" silicon by disabling an entire GPC worth of CUDA cores, leaving the chip with 2,560 out of its 3,072 CUDA cores enabled, besides 160 TMUs, 64 ROPs, 320 Tensor cores, and 40 RT cores. The memory subsystem is untouched. 8 GB of memory ticks at 14 Gbps and sits across a 256-bit wide GDDR6 memory interface, churning out 448 GB/s of memory bandwidth. The GPU clock speeds are increased, too, with up to 1770 MHz GPU Boost frequency, compared to 1620 MHz on the original RTX 2070. Another neat little perk of being based on the "TU104" silicon is NVLink support, which enables 2-way SLI.

In this review, we're testing the Zotac GeForce RTX 2070 Super AMP Extreme, which is the company's flagship variant for the RTX 2070 Super. Zotac uses a large triple-slot, triple-fan cooler on their card, which will definitely help with temperatures. The card features a factory overclock to 1830 MHz GPU Boost against reference speeds of 1770 MHz. All this comes at a premium of just $10 over the $499 MSRP of the RTX 2070 Super.
