24GB GDDR6X for 4K workflows
The ASUS ROG Strix GeForce RTX 4090 OC Edition targets enthusiasts and professionals who need 24GB of GDDR6X memory on a 384-bit bus. It connects via PCI Express 4.0 and drives up to four displays through two HDMI 2.1 and three DisplayPort 1.4a outputs. The card hits a 2640 MHz boost clock with a 450W TDP and requires a 1000W power supply.
Stepping up from 10GB or 12GB cards
Moving from a 10GB or 12GB GPU removes the VRAM ceiling that forces texture downsampling in modern titles and professional scenes. The 24GB frame buffer lets you hold full 4K and 8K assets without streaming stalls. The jump pays off when your current card hits 100 percent memory utilisation at 4K ultra settings or in large 3D scenes.
PCIe 4.0 x16 bandwidth ceiling
The PCI Express 4.0 x16 link caps theoretical throughput at 32 GT/s per lane. On platforms limited to PCIe 3.0 the same slot delivers half that bandwidth, which can surface in compute workloads that stream heavy textures each frame. HDMI 2.1 and DisplayPort 1.4a set the external display limits: 7680 x 4320 maximum resolution with HDCP 2.3 protection.

Questions about this item
Will the 3.5-slot, 357.6 mm long card fit my ATX case?
The card uses a 3.5-slot form factor and measures 357.6 mm long by 70.1 mm tall. Verify your case lists at least 358 mm GPU clearance and room for three expansion slots.
Which power connector does the 16-pin plug need, and what mistake do builders make?
It requires one 16-pin (12VHPWR) connector fully seated until the latch clicks; the common error is leaving a gap that can overheat. Route cables without sharp bends near the plug.
What maintenance does the triple-fan vapor-chamber cooler need later?
Dust the three Axial-tech fans and fin array every few months with compressed air. The 15K capacitors and vapor chamber are sealed and need no user service.
