ASUS ROG Astral GeForce RTX 5090 32GB GDDR7 White graphics card

SKU CH-TT6C-HEE42

32 GB of GDDR7 memory on a 512-bit bus drives 21760 CUDA cores at up to 2580 MHz boost via PCIe 5.0

  • Graphics processorGeForce RTX 5090
  • Memory capacity32 GB
  • Interface typePCI Express 5.0
  • CUDA core count21760
  • Highest resolution7680 × 4320
  • Boost frequency2580 MHz
  • 32 GB GDDR7 memory enables high-resolution 4K and 8K gaming
  • 21,760 CUDA cores deliver massive parallel compute for rendering and AI workloads

32GB GDDR7 AI Accelerator

The ASUS ROG Astral GeForce RTX 5090 delivers 32GB of GDDR7 memory across a 512-bit interface for large-model inference and 8K content creation. Its 21760 CUDA cores handle intensive ray-tracing and compute workloads. The white finish suits clean-build aesthetics. Target users are researchers, studios and enthusiasts needing maximum frame-buffer capacity.

PCI Express 5.0 Bandwidth Ceiling

The card communicates over a PCI Express 5.0 link, so full throughput depends on a compatible motherboard and CPU. Older platforms will limit the 28000 MHz effective memory speed to lower generation rates. Display outputs include 2 x HDMI 2.1b and 3 x DisplayPort 2.1a for multi-monitor arrays up to 7680 x 4320 resolution. OpenGL 4.6 support is standard.

Triple-Slot White Build Implications

A triple-slot cooler with a white shroud and backplate demands ample case clearance and a high-wattage power supply with native 12VHPWR connectors. The 2580 MHz boost clock and 2610 MHz game clock require sustained airflow to maintain performance. Mounting orientation follows standard ATX layout; verify bracket alignment before installation.

Questions about this item

Is the ROG-ASTRAL-RTX5090-O32G-WHITE the only model in this series?

The card is the ROG-ASTRAL-RTX5090-O32G-WHITE with 32GB GDDR7 on a 512-bit bus; no other capacities or colour variants are listed.

What does the 2580 MHz boost clock mean for actual gaming performance?

The GPU can reach 2580 MHz under load, while the game clock sits at 2610 MHz, so sustained speeds in typical titles will hover around those figures with the 21760 CUDA cores driving frame rates.

How does the PCI Express 5.0 interface affect data throughput with this card?

The board uses a PCI Express 5.0 connection, matching the RTX 5090 chipset and allowing the 512-bit GDDR7 memory subsystem to transfer data at the full 28000 MHz effective rate without slot limitation.
