SKU CH-HCTB-XJ7Y1

High-performance GPU with 16GB GDDR6X memory, factory overclocked to 2670 MHz and cooled by a 3.5-slot vapor-chamber design with Axial-tech fans delivering 23% more airflow

  • Boosted frame rates with DLSS 3 Tensor technology
  • 16 GB GDDR6X memory handles 4K textures smoothly
  • Factory OC mode reaches 2670 MHz for extra speed
  • Vapor chamber and milled heatspreader lower GPU temperatures
  • Triple Axial-tech fans deliver 23% more airflow

ROG Strix 4080 SUPER identity

The ASUS ROG Strix GeForce RTX 4080 SUPER OC Edition is a 16GB GDDR6X graphics card built for enthusiasts who need high frame rates at 4K resolution. Factory overclocking and a premium cooling stack target users who want maximum performance without manual tuning.

PCIe 4.0 bandwidth ceiling

The card connects through a PCIe 4.0 x16 slot, delivering up to 16 GT/s per lane. That interface caps total throughput, so workloads that saturate the bus will not benefit from a faster motherboard link. Display outputs use HDMI 2.1a and DisplayPort 1.4a for modern high-refresh panels.

16GB VRAM capacity gate

With 16GB of GDDR6X memory, the frame buffer decides whether heavy 4K textures, large creative projects, or multi-monitor setups fit without swapping. If your typical scene stays inside that limit the card runs unrestricted; if it spills over, performance drops sharply regardless of clock speed.

Questions about this item

Should I pick the OC mode at 2670 MHz or the default 2640 MHz?

OC mode runs the GPU at 2670 MHz for higher frame rates in demanding titles, while default mode runs at 2640 MHz with slightly lower power draw and noise. Both use the same 16GB GDDR6X memory and cooling hardware.

What does the 2670 MHz boost clock actually deliver inside a PC?

The 2670 MHz OC boost raises shader throughput so games hit higher average frame rates at 4K with ray tracing on. The 3.5-slot vapor-chamber cooler keeps temperatures in check so the clock holds under sustained load.

How does the PCIe 4.0 x16 link affect this card?

The card uses a PCIe 4.0 x16 interface, providing full bandwidth for the RTX 4080 SUPER GPU. On a PCIe 3.0 motherboard the link runs at half speed, which can cap peak throughput in extreme 4K workloads.
