ZOTAC GeForce RTX 4070 SUPER Twin Edge 12GB

The ZOTAC GeForce RTX 4070 SUPER Twin Edge is a 12GB graphics card built for gamers and creators who want Ada Lovelace performance in a compact dual-fan design. It delivers DLSS 3 frame generation and full ray tracing support for modern titles at high settings. The card fits standard builds with a PCI Express 4.0 x16 interface and a 220W thermal design power.

PCI Express 4.0 x16 interface limits

The card uses a PCI Express 4.0 x16 slot, so bandwidth tops out at the Gen 4 ceiling rather than the newer Gen 5 speeds available on latest platforms. Display outputs consist of one HDMI 2.1a and three DisplayPort 1.4a connectors, capping external signalling at those respective link rates. The 192-bit memory bus and 21 Gbps GDDR6X set the maximum memory throughput for the GPU.

12GB GDDR6X on a 192-bit bus

The 12GB GDDR6X frame buffer across a 192-bit bus decides whether this model suits your workload; it provides enough capacity for 1440p ultra and entry 4K gaming but can become a constraint in heavy 4K texture packs or large creative datasets. Buyers needing more VRAM for professional 3D rendering or 4K high-refresh gaming should look at wider-bus alternatives.

Questions about this item

Is the 12GB GDDR6X version the only capacity offered for this Twin Edge model?

The Twin Edge is listed with 12GB GDDR6X on a 192-bit bus at 21 Gbps; no other memory capacities appear in the specifications for this card.

What does the 2475 MHz boost clock mean for actual frame rates?

The 2475 MHz boost clock is the peak GPU frequency under load; real-world frame rates depend on the game, resolution and power limit, but the card targets 1440p and 4K gaming with DLSS 3 frame generation.

How does the PCI Express 4.0 x16 interface affect bandwidth?

The card uses a PCI Express 4.0 x16 link, providing up to 32 GB/s of host bandwidth; it will also run at PCI Express 3.0 speeds if the motherboard only supports that generation.
