Asus ROG Strix GeForce RTX 4070 Super specifications and in-depth review

Asus ROG Strix GeForce RTX 4070 Super

Manufacturer: Asus

The Asus ROG Strix GeForce RTX 4070 Super is a graphics card built on NVIDIA's Ada Lovelace architecture, produced using a 5 nm process with 35,800 million transistors. It supports ray tracing, DLSS, stereoscopic 3D, and Intel Resizable BAR, and includes RGB lighting alongside multi-display support for up to four screens simultaneously.

The card operates at a base clock of 1,980 MHz boosting to 2,475 MHz, with 7,168 shading units, 224 texture mapping units, and 80 render output units delivering a texture rate of 554.4 GTexels/s and a pixel rate of 198 GPixel/s. It carries 12GB of GDDR6X VRAM on a 192-bit bus running at an effective 21,000 MHz for up to 504.2 GB/s of bandwidth, with ECC memory support included. Output connectivity spans two HDMI 2.1a ports and three DisplayPort outputs, and the card has a TDP of 225W with dimensions of 338.9 mm × 149.4 mm.

Pros
  • Two HDMI 2.1a ports provide more flexibility for connecting HDMI displays simultaneously compared to cards with a single HDMI output
  • Ray tracing and DLSS are both supported, enabling hardware-accelerated rendering and upscaling in compatible applications
  • ECC memory support adds data integrity protection for workloads sensitive to memory errors
  • Intel Resizable BAR is included, allowing more efficient CPU-to-GPU data transfers on compatible systems
  • RGB lighting is built in, offering visual customization without the need for additional hardware
  • A 225W TDP places relatively modest power demands on the system compared to higher-tier cards in the same category
Cons
  • The 192-bit memory bus width limits memory bandwidth scaling for workloads that push memory throughput heavily
  • No USB-C display output is available, which may require adapters for certain modern monitors
  • At 338.9 mm in length, the card still requires adequate case clearance and may not fit compact builds
  • Air-water hybrid cooling is absent, so all heat dissipation depends on the air-cooling solution alone
Who is this for?

The Asus ROG Strix GeForce RTX 4070 Super suits users who want a capable graphics card for ray tracing and DLSS-enabled workloads without stepping into the highest TDP bracket, as its 225W power draw is relatively manageable for mid-to-full-sized desktop builds. The dual HDMI 2.1a ports combined with three DisplayPort outputs make it a practical choice for users running multi-monitor setups, particularly those mixing HDMI and DisplayPort displays. ECC memory support and DPFP capability also make it a reasonable fit for users with mixed gaming and precision compute workloads who need a degree of memory reliability.

Who is this NOT for?

Users with workloads that demand high memory bandwidth may find the 192-bit bus width a limiting factor, as it caps the memory throughput at 504.2 GB/s regardless of other capabilities. The card's 338.9 mm length makes it unsuitable for compact or small-form-factor cases where physical clearance is restricted. Those who rely on USB-C for display connectivity will also find no native support here, and users who want a completely understated build aesthetic may be put off by the presence of RGB lighting with no indication of a disable option in the provided data.

General info:

GPU architecture Ada Lovelace
Thermal Design Power (TDP) 225W
PCI Express (PCIe) version 4
semiconductor size 5 nm
number of transistors 35800 million
Has air-water cooling
width 338.9 mm
height 149.4 mm

Underpinned by the Ada Lovelace architecture and manufactured on a 5 nm process, the card integrates 35,800 million transistors and connects via a PCIe 4 interface. It has a TDP of 225W and measures 338.9 mm in width by 149.4 mm in height, so case clearance should be confirmed before installation. Air-water hybrid cooling is not available on this model, with thermal management handled entirely by the air-cooling solution.

Final Verdict

The Asus ROG Strix GeForce RTX 4070 Super is a well-specified graphics card that covers the essentials for modern desktop use, with ray tracing, DLSS, ECC memory support, and a dual HDMI 2.1a plus triple DisplayPort output configuration that offers genuine flexibility for multi-display setups.
