GeForce RTX 4070 SUPER 12GB

The ASUS ATS GeForce RTX 4070 SUPER EVO OC Edition is a graphics card built on the NVIDIA Ada Lovelace architecture for gamers and creators targeting high-refresh 1440p play and entry 4K workloads. It fits a 2.5-slot footprint and uses Axial-tech fans with dual ball bearings and 0dB stop mode for quiet operation in compact builds.

PCI Express 4.0 interface and 192-bit memory bus

The card connects through a PCI Express 4.0 x16 slot and feeds the GPU through a 192-bit bus paired with 12GB of GDDR6X running at 21 Gbps. That bus width is the single spec that defines how much data can move each cycle, so it decides whether the card matches your resolution and texture-quality targets.

12GB GDDR6X capacity for 1440p and light 4K

The 12GB frame buffer comfortably holds high-resolution textures, DLSS 3 frame-generation data and ray-tracing structures at 1440p ultra settings. At 4K with maximum ray-tracing loads the buffer can fill, forcing texture streaming or lower settings, while compute-heavy AI batches may also exceed the available memory.

Questions about this item

What does the 2550 MHz boost clock mean for actual frame rates?

The 2550 MHz boost clock is the peak GPU frequency in OC mode; real-world frame rates depend on the game, resolution, and power limit, but the higher clock gives extra headroom over the 2520 MHz default mode.

How does the PCIe 4.0 interface affect bandwidth?

PCIe 4.0 provides up to 16 GT/s per lane; the card uses a 16-lane link, so the practical ceiling is the slot's 4.0 speed, not the card itself.

Will the 2.5-slot cooler fit in a compact case?

The 2.5-slot design measures roughly two and a half expansion slots wide; verify your case's GPU clearance and motherboard spacing before installing.
