ASUS RTX 4070 Ti TUF Gaming OC 12GB

Tear Down

Taking the card apart was pretty easy with the majority of the screws being on the rear, a few on the I/O and then once the main shroud and heatsink cooler are removed, more screws are revealed that hold the backplate on.

The heatsink is split into two large sections with heatpipes passing through to each end to help dissipate the heat in the most efficient way. The cooler makes direct contact with the GPU core and GDDR6X memory chips on one plate, while extra plates and heat pads are in place that makes contact with the VRMs.

The PCB is a bit larger than what we’re used to on NVIDIA cards but is extremely well-organised and includes 13 phases in total which are split between the GPU and memory. The 11 for the GPU are all made by Vishay and are SiC639 power stages that are rated for 50 A of continuous current each along with the 2 phases for the memory utilising exactly the same components. 

The GPU phases are managed by the UPI UP9512r controller while the memory phases are managed by the UPI UP9529Q controller which is pretty typical of what we’ve seen before.

So a pretty beefy cooler for a 4070 Ti and underneath, everything is what you’d expect from a TUF card. While ASUS have the STRIX range of GPUs that sit above the TUF range, it’s clear to see that ASUS has added a lot more to their TUF cards in terms of quality materials and better designs of both the PCB and the cooler, so let’s take a look at how it compares to other cards.
