Inno3D RTX 4070 Ti Graphics Card Review

Tear Down
Taking the card apart was very easy and consists of 8 screws to remove the backplate, along with the 4 screws that hold the cooler onto the PCB, making contact with the GPU core. The IO also has 3 small screws if wanting to remove that, and then if wanting to take the shroud and heatsink apart, there’s a further 3 screws on the outside of the shroud, and 3 on the inside of the cooler making it easy to fully strip down and clean.
The PCB actually shocked me as to how small it is, and is very reminiscent of the NVIDIA FE PCB with a v-shaped cutout. It’s extremely compact but doesn’t feel like any corners have been cut. There’s some connectors in the bottom right of the board for the triple fan, and plenty of space for more memory modules, so maybe we could see a higher memory capacity card at a later date? While that’s unlikely, it’s not completely out of the question. In terms of power delivery, the card features an 11-phase setup for the GPU, and a further 2 phases for the memory and are all made by Alpha and Omega Semiconductors.
The GPU phases are managed by a Richtek RT8848C controller, while the memory is managed by the Richtek RT8843B controller. All phases for both the GPU and memory are using the AOZ5311NQI power stage modules are rated for 55A of continuous current.
The heatsink that keeps this circuitry under control is split with a copper base for the GPU, aluminium base for the memory and a heatpipe for the phases in a hope to split the heat to different areas on the finned heatsink. Including the MOSFET heatpipe, there’s a total of eight 6mm heatpipes, and is a solution that we’ve seen before on other cards.
Also to help with temperatures, the backplate which is on the thicker side, compared to other models, has heatpads to help dissipate heat away.
So a pretty hefty cooler for a 4070 Ti, and a unique way of working in terms of the mixed plates that make contact with various parts of the card, but let’s see how the card compares in terms of performance to other cards we’ve tested.
