GIGABYTE GeForce RTX 3080 Ti XTREME WATERFORCE WB 12G graphics card

SKU CH-KA8B-D1K7H

Water-cooled RTX graphics card with 12 GB GDDR6X memory, 10240 CUDA cores and a 1770 MHz core frequency

  • Type of memoryGDDR6X
  • Boost clock reaches 1770 MHz for faster frame rates
  • 12 GB GDDR6X memory handles large textures and datasets
  • 384-bit bus with 912 GB/s bandwidth feeds the GPU without bottlenecks
  • Pre-installed water block with G1/4 fittings simplifies custom-loop cooling
  • PCIe 4.0 x16 interface provides full bandwidth to modern platforms

Core specifications

The GIGABYTE GeForce RTX 3080 Ti XTREME WATERFORCE WB 12G is a factory water-cooled graphics card built for enthusiasts who want maximum thermal headroom in a custom loop. It delivers 10240 CUDA cores and 12 GB of GDDR6X memory across a 384-bit bus for high-resolution gaming and compute workloads.

Upgrade path

This card replaces an air-cooled RTX 3080 Ti or earlier flagship when noise and temperature limits are the bottleneck. The 1770 MHz boost clock over the 1665 MHz reference speed makes the jump worthwhile only if your loop can dissipate the extra heat and your power supply meets the 750W recommendation.

Build integration

The dual-slot 252 mm by 163 mm PCB fits standard ATX layouts and connects via PCI-E 4.0 x 16 with two 8-pin power inputs. Three DisplayPort 1.4a and two HDMI 2.1 outputs drive up to four displays at 7680x4320 while G1/4 fittings integrate cleanly into existing hard-tube or soft-tube circuits.

Questions about this item

Will the 252 mm length and 29 mm height fit my case?

The card measures 252 mm long, 163 mm wide and 29 mm high, occupying two expansion slots; verify your case clearance against those dimensions.

Which power cables must I connect to the two 8 pin sockets?

Connect two separate 8 pin PCIe power cables from a 750 W or larger supply; using a single daisy chained cable can cause instability.

When should I plan to replace the coolant in the G1/4" loop?

Most builders drain and refill the custom loop every 12 to 24 months to prevent algae and corrosion buildup.
