Ready for 4K gaming and content creation
This ROG Strix GeForce RTX 3080 Ti graphics card targets enthusiasts who need high frame rates at 4K resolution and reliable throughput for creative workloads. The 12GB GDDR6X frame buffer and 10240 CUDA cores give it the raw capacity for modern titles and GPU-accelerated applications. It connects through a PCI Express 4.0 x16 slot and drives up to four displays via two HDMI 2.1 and three DisplayPort 1.4a outputs.
12GB GDDR6X on a 384-bit bus
The single specification that decides fit is the 12GB GDDR6X memory running across a 384-bit interface at 19 Gbps. This combination delivers the bandwidth needed for 4K textures, ray-traced scenes and large dataset processing without swapping to system memory. If your workload exceeds 12GB of VRAM, you must look at a higher-capacity model; otherwise this configuration matches the demands of current high-end gaming and professional pipelines.
Axial-tech fans and 2.9-slot cooler
The Axial-tech fan design uses additional blades and a reversed centre fan to move more air through a 2.9-slot heatsink that expands surface area over prior designs. Super Alloy Power II components — premium alloy chokes, solid polymer capacitors and high-current power stages — reduce electrical loss and keep temperatures lower under sustained load. In typical gaming sessions the card runs at boost clocks of 1815 MHz in Gaming mode or 1845 MHz in OC mode while staying within its thermal envelope and keeping acoustic output controlled.

Questions about this item
What does the 1845 MHz OC boost clock mean once the card is inside my PC?
The 1845 MHz OC boost clock is the peak frequency the GPU targets under load when OC mode is selected in GPU Tweak II; actual sustained clocks depend on power limit, temperature and the workload you run.
How does the PCI Express 4.0 x16 interface cap performance in practice?
PCI Express 4.0 x16 provides double the bandwidth of 3.0, removing the bus bottleneck for the RTX 3080 Ti so the 12GB GDDR6X memory and 10240 CUDA cores can feed data at full speed.
What clearance and power connections does the 2.9-slot design need to fit and mount?
The 2.9-slot cooler occupies nearly three expansion slots and requires a case with sufficient length and height clearance plus three 8-pin PCIe power connectors for the Super Alloy Power II delivery system.
