TUF Gaming GeForce RTX 4090 24GB

This ASUS graphics card uses the NVIDIA Ada Lovelace architecture with 16384 CUDA cores and 24GB of GDDR6X memory on a 384-bit bus. It connects via PCI Express 4.0 x16 and outputs to four displays through two HDMI 2.1a and three DisplayPort 1.4a ports.

Best for 4K gaming and heavy creative workloads

The 2595 MHz OC boost clock and DLSS 3 frame generation suit enthusiasts targeting high refresh rates at 4K or professionals needing large VRAM for rendering. Buyers with compact cases, modest power supplies or 1440p-only monitors should consider smaller cards.

24GB GDDR6X memory capacity

The 24GB frame buffer is the decisive spec for 4K gaming with high-resolution textures, 3D rendering and AI workloads that exceed 12GB or 16GB limits. If your applications fit in less VRAM, a lower-tier GPU will cost less and draw less power.

Questions about this item

Is the 24 GB GDDR6X version the only capacity available for this TUF Gaming RTX 4090 model?

Yes, the TUF-RTX4090-O24G-OG-GAMING comes in a single 24 GB GDDR6X configuration with a 384-bit memory interface. There are no other memory capacities offered for this specific model.

What does the 2595 MHz OC mode boost clock deliver in actual workloads?

The 2595 MHz OC mode boost clock is the maximum frequency the GPU targets under load. Sustained speeds depend on power limits, thermals and the specific application. The default mode runs at 2565 MHz if you prefer a lower target.

How does the PCIe 4.0 x16 interface affect data throughput with this card?

The card uses a PCI Express 4.0 x16 link. It is backward compatible with PCIe 3.0 slots, though peak transfer rates will be limited to the slot's generation.
