ASUS ROG Strix GeForce RTX 4070 Ti SUPER OC graphics card: specs and fit

The ASUS ROG Strix GeForce RTX 4070 Ti SUPER OC Edition (model ROG-STRIX-RTX4070TIS-O16G-GAMING) is a high-end graphics card for desktop PCs. It uses NVIDIA's Ada Lovelace architecture and carries 16GB of GDDR6X memory. This page explains what the main specifications mean and what to confirm about your PC before fitting a card this size.

Ada Lovelace, DLSS 3 and ray tracing

Ada Lovelace is the architecture behind NVIDIA's GeForce RTX 40 series. The listing highlights two kinds of dedicated hardware. Third-generation RT Cores handle ray tracing, a lighting technique that simulates how light bounces in a scene; ASUS quotes up to 2x the ray tracing performance of the previous generation. Fourth-generation Tensor Cores run AI tasks, including DLSS 3, which uses AI to upscale images and generate extra frames. ASUS states up to 4x performance with DLSS 3 compared with brute-force rendering. These are best-case figures for supported games, and results vary by title and settings.

16GB of GDDR6X memory

Video memory holds textures and other game data. Sixteen gigabytes of GDDR6X is typically comfortable for high-resolution gaming, high-detail texture packs, and creative work such as video editing or 3D rendering. Resolution, texture quality and ray tracing all increase memory use.

Clock speeds and OC mode

This is an "OC Edition", meaning ASUS ships it with a factory overclock. The listing gives 2700 MHz in OC mode and 2670 MHz in default mode. Clock speed is one factor in performance; the number of cores and memory bandwidth also matter, so the figure can't be compared across different card families.

Cooling

ASUS lists Axial-tech fans scaled up for 31% more airflow, a vented backplate and power sensing. Large cards like this use thick heatsinks and several fans to keep temperatures and noise in check under load. The card also supports Aura Sync, ASUS's RGB lighting software.

Connections

The card uses PCIe 4.0 and offers HDMI 2.1a and DisplayPort 1.4a outputs. HDMI 2.1 is typically needed for 4K at high refresh rates on a television, while DisplayPort 1.4a suits high-resolution PC monitors. The listing does not give the exact port count, so check the full specification.

Size and power

The card is about 13.2 inches long and 5.9 inches wide (roughly 33.5 x 15 cm) and weighs 3.9 lb. It occupies several expansion slots in a case, though the listing gives no slot count. Cards of this class draw a lot of power and need the connectors listed in the manual, along with a power supply of suitable wattage. The listing's "power sensing" refers to monitoring of the power connection; follow the manufacturer's guidance for cables and installation.

Who it suits

It suits PC gamers building or upgrading a desktop for high-resolution or high-refresh-rate play, and creators who benefit from a large pool of video memory and AI-accelerated tools. It is more card than a PC used for office work or older games needs.

What to check before you buy

• Case clearance: measure the space for a card over 13 inches long and several slots thick.
• Power supply: check the card's recommended minimum wattage and its power connectors in the manual.
• Motherboard slot: confirm a full-length PCIe x16 slot; PCIe 4.0 cards typically work in other generations, perhaps at reduced bandwidth.
• Display connections: make sure your monitor or TV cables match HDMI 2.1a or DisplayPort 1.4a.
• Processor match: a much older CPU can hold back a card of this class.
• Weight: check whether the case needs a support bracket for a heavy card.

The short version

• A 16GB GDDR6X graphics card with NVIDIA Ada Lovelace architecture, model ROG-STRIX-RTX4070TIS-O16G-GAMING.
• DLSS 3, 3rd-generation RT Cores and 4th-generation Tensor Cores.
• 2700 MHz in OC mode and 2670 MHz in default mode.
• Axial-tech fans, vented backplate, PCIe 4.0, HDMI 2.1a and DisplayPort 1.4a.
• About 13.2 inches long and 3.9 lb.
