The ASUS ROG Strix GeForce RTX 4070 OC Edition is a graphics card for gaming PCs, built around NVIDIA's RTX 4070 chip with 12GB of GDDR6X memory. ASUS pairs the chip with a large three-fan cooler and a factory overclock. This page covers what the main specs mean and what to confirm about your own PC.
The GPU and 12GB memory
The card uses NVIDIA's Ada Lovelace architecture. The listing says it has 4th generation Tensor Cores and 3rd generation RT Cores. Tensor Cores handle AI-based work, including DLSS, while RT Cores accelerate ray tracing, a lighting technique that models how light bounces around a scene. NVIDIA claims up to 2x ray tracing performance from the RT Cores, and the card has 12GB of GDDR6X memory, which holds game textures and other data.
What DLSS 3 does
DLSS 3 is NVIDIA's upscaling and frame generation technology. It renders a game at a lower internal resolution and uses AI to produce a sharper image, and it can also generate extra frames. The listing says up to 4x performance with DLSS 3 compared with brute-force rendering. This only applies to games that support DLSS 3, and results vary from title to title.
Clock speeds
This is the OC Edition. ASUS lists 2640 MHz in OC mode and 2610 MHz in default mode. These are boost clocks that the card can reach under suitable conditions, and they depend on temperature and power. The included GPU Tweak III software lets you adjust performance, thermal controls and monitor the system.
Cooling design
Cooling is the headline of the Strix design. Three Axial-tech fans are scaled up for 31% more airflow, according to ASUS. The cooler takes up 3.12 slots, a large fin array tuned for airflow. The shroud, frame and backplate are diecast metal, which adds rigidity and is vented to help heat escape. ASUS says the card is smaller than before.
Power delivery and build
ASUS describes digital power control with high-current power stages and 15K capacitors, and says Auto-Extreme automated manufacturing is used for higher reliability.
Connections and size
The card uses PCIe 4.0, with HDMI 2.1 and DisplayPort 1.4a outputs. It measures about 13.3 x 5.9 x 2.4 inches (34 x 15 x 6 cm) and weighs 3.9 lb (about 1.8 kg), so it is a heavy card.
Who it suits
It fits people building or upgrading a gaming desktop who want a large, well-cooled card with DLSS 3 and ray tracing. Smaller cases, and those with limited power supplies, need extra checks.
What to check before you buy
- Confirm the card fits your case: length, width and the 3.12-slot thickness.
- Check your power supply wattage and connectors against NVIDIA's and ASUS's requirements for this card.
- Make sure your motherboard has a free PCIe x16 slot; PCIe 4.0 is used but older slots usually work too.
- Check that your monitor has HDMI 2.1 or DisplayPort inputs to match the card's outputs.
- Consider the weight and whether your case needs a support bracket.
- Look at what your games support: DLSS 3 and ray tracing are game-specific.
