MSI GeForce GTX 980 Ti GAMING 6G graphics card

6GB GDDR5 frame buffer

The card ships with 6GB of GDDR5 memory on a 384-bit bus, providing enough bandwidth for high-resolution textures and compute workloads. It targets enthusiasts who want 4K-capable performance without moving to a newer architecture. The 2816 CUDA cores and three selectable BIOS profiles let users trade clock speed for acoustics. DirectX 12 and OpenGL 4.4 support cover current API requirements.

Sustained load behaviour

Under continuous load the GPU can run at the Gaming Mode clocks of 1140 MHz base and 1228 MHz boost, or drop to Silent Mode at 1000 MHz base and 1076 MHz boost for quieter operation. OC Mode raises the ceiling to 1178 MHz base and 1279 MHz boost with memory reaching 7096 MHz effective. The triple-fan cooler is designed to maintain these frequencies over extended sessions rather than only brief bursts.

PCI Express 3.0 x16 limits

The PCI Express 3.0 x16 interface delivers up to 16 GT/s per lane, which is sufficient for the card's 384-bit memory subsystem and 4K output at 4096 x 2160. Display outputs include one HDMI, three DisplayPort and one dual-link DVI-I, supporting four simultaneous monitors. Bandwidth saturation only becomes a concern with multi-GPU configurations or external capture devices not present in this single-card scenario.
