MSI RTX 4070 Ti VENTUS 3X E 12G OC graphics card

12GB GDDR6X frame buffer

The card ships with 12GB of GDDR6X memory running at an effective 21000 MHz across a 192-bit interface. That capacity targets 1440p and 4K gaming workloads as well as creative tasks that benefit from fast VRAM. The 7680 CUDA cores and 2640 MHz boost clock provide the compute headroom to keep the memory fed in modern titles. PCI Express 4.0 ensures the host link does not become a bottleneck.

Sustained load thermal behavior

A triple-fan cooler dissipates the 285W thermal design power during extended sessions. The design moves heat away from the GPU and memory without relying on a single high-speed fan, which helps maintain consistent clocks over long rendering or gaming periods. A 700W power supply is recommended to keep the 16-pin connector fed cleanly under continuous draw. The ATX form factor fits standard chassis layouts.

192-bit memory interface width

The 192-bit bus width is the specification that determines whether this model matches a given bandwidth requirement. Narrower than wider designs, it favors workloads where 12GB capacity matters more than peak throughput. Buyers chasing maximum memory bandwidth for compute-heavy pipelines should verify the bus width against their application needs. All other specs scale around this constraint.
