Manufacturer description
The ASUS TUF Gaming GeForce RTX 3070 Ti OC Edition pairs NVIDIA's Ampere architecture with 8GB of GDDR6X memory on a PCIe 4.0 interface, built for ray-traced gaming and DLSS-boosted frame rates. Ampere streaming multiprocessors bring up to 2X the FP32 throughput of the prior generation. 2nd-gen RT cores double ray-tracing throughput over 1st-gen RT cores, and 3rd-gen Tensor cores run DLSS, with support for output up to 8K (7680 x 4320). The cooling is what sets the TUF line apart. Three Axial-tech fans push air through a MaxContact heatsink. The fans have extra blades, and the center fan…
