32 GB GDDR7 graphics card
The ASUS ROG Astral GeForce RTX 5090 OC Edition is a high-end graphics card built for 4K gaming and professional creative workloads. It features 21760 CUDA cores and 32 GB of GDDR7 memory running across a 512-bit interface. The boost clock reaches 2610 MHz in OC mode and 2580 MHz in default mode. This card targets enthusiasts who need maximum frame rates and memory capacity.
PCI Express 5.0 interface limits
The card connects through a PCI Express 5.0 slot, which provides the bandwidth ceiling for the GPU and its 28 Gbps memory. Display outputs are limited to two native HDMI 2.1b ports and three native DisplayPort 2.1a ports, supporting up to four simultaneous monitors. The maximum digital resolution is 7680 x 4320. SLI multi-GPU configurations are not supported on this model.
Black finish and connector layout
The black shroud houses a triple-slot cooling assembly that occupies significant case space and requires a robust power supply. Two HDMI 2.1b and three DisplayPort 2.1a connectors sit along the rear bracket, allowing flexible multi-monitor arrangements without adapters. The 512-bit memory bus and GDDR7 modules demand careful airflow management to sustain the 28000 MHz effective clock during extended sessions.

Questions sur cet article
Should I pick the OC mode or the default mode for the RTX 5090 32 GB GDDR7 card?
OC mode runs the boost clock at 2610 MHz while default mode runs at 2580 MHz; both use the same 21760 CUDA cores and 32 GB GDDR7 memory, so choose OC mode if you want the factory-overclocked speed.
What does the 28000 MHz effective memory clock deliver in a real system?
The 28 Gbps GDDR7 memory across a 512-bit bus feeds the 21760 CUDA cores with very high bandwidth, letting the RTX 5090 GPU handle 4K and 8K workloads with large texture sets.
How does the PCI Express 5.0 interface cap performance in practice?
The card uses a PCI Express 5.0 slot for maximum host bandwidth; actual throughput will depend on your motherboard and CPU support for the same generation.
