GIGABYTE GeForce RTX 4090 GAMING OC 24G graphics card

SKU CH-DVZZ-MHEAC

A graphics card with 24 GB of GDDR6X memory, 16384 CUDA cores and a 2535 MHz core clock on a PCIe 4.0 x16 interface

  • Memory TypeGDDR6X
  • 24 GB GDDR6X memory enables high-resolution texture workloads
  • 16384 CUDA cores accelerate parallel compute tasks
  • 2535 MHz boost clock delivers high single-thread performance
  • PCIe 4.0 x16 interface provides full bandwidth to the platform
  • 384-bit bus with 21 Gbps memory rate sustains data throughput

Core specification

This GIGABYTE GeForce RTX 4090 GAMING OC 24G graphics card equips 24 GB GDDR6X memory across a 384-bit bus running at 21 Gbps. The GPU delivers 16384 CUDA cores with a boost clock of 2535 MHz, exceeding the reference 2520 MHz. It connects via PCI Express 4.0 x16 and draws power through a single 16-pin connector.

Upgrade threshold

The card replaces any GPU limited to 10 GB or 12 GB buffers when workloads demand 24 GB frame storage at 7680x4320 resolution. Moving from a prior 384-bit flagship is justified only when the 2535 MHz uplift and 1000W platform headroom translate into measurable throughput for sustained 4K or 8K pipelines.

Fit and alternatives

Creators and engineers running multi-monitor arrays up to four displays at 7680x4320 will utilise the three DisplayPort 1.4a and one HDMI 2.1a outputs fully. Builds restricted to cases shorter than 340 mm, PSUs below 1000W, or workflows needing only 1080p output should select a smaller, lower-power model.

Questions about this item

Will the 340 mm length and 75.2 mm height fit my ATX case and clear the side panel?

The card measures 340 mm long, 150.2 mm wide and 75.2 mm tall on an ATX PCB; verify your case’s GPU clearance and side-panel gap before ordering.

Which power connector does the 16-pin interface require and how should it be seated?

Use a native 12VHPWR 16-pin cable or the supplied adapter; push it straight in until the latch clicks, avoiding any bend near the plug.

When should I plan to replace the thermal paste on the GeForce RTX 4090 core?

Re-paste only if temperatures rise noticeably after several years; the factory paste is rated for long-term use under normal gaming loads.
