Following on from our full review of the RTX 4070 Ti, we are already back with a look at another AIB model. Enter the Inno3D RTX 4070 iChill X3, offering a 60MHz factory overclock, 320W power limit and triple-fan cooler. Could this be one to add to your shortlists if you are in the market for a new graphics card?

If you haven't already read or watched our full RTX 4070 Ti review, I'd recommend doing so to get an idea of exactly how this new GPU stacks up in the wider context of the 40-series and RDNA 3 competitors. This review is more focused on the Inno3D RTX 4070 Ti iChill X3 itself, as we look at the design, thermals, acoustics, overclocking and more.

First, for a quick spec recap. We already mentioned that RTX 4070 Ti uses the AD104 die, measuring 295mm². Accordingly, transistor count is reduced to 35.8 billion, down from 45.9 billion with AD103. The fundamental building blocks are still the same of course, with the RTX 4070 Ti offering a total of 60 Streaming Multiprocessors (SMs), each housing 256 CUDA Cores, for a total of 7680. We also find 60 RT cores, 240 Tensor cores, 240 Texture Units, and 80 ROPs.

TSMC's N4 node has Nvidia cranking up the clock speed significantly this generation, with the RTX 4070 Ti sporting a 2610MHz rated boost clock. Inno3D has increased this further, with a 60MHz factory overclock, bringing speeds up to 2670MHz.

The memory configuration is another area where AD104 has been cut-back significantly. The memory interface has been reduced to 192-bit, and even with 12GB GDDR6X running at 21Gbps, that brings total memory bandwidth down to 504 GB/s, lower than even the RTX 3070 Ti. That said, there has been a substantial upgrade to the L2 cache with the Ada architecture, with the RTX 4070 Ti now offering 49MB, compared to just 6MB for GA102.

Considering these cut-backs, power draw is naturally lower than the RTX 4080, with the 4070 Ti boasting a reference 285W TGP. Inno3D has also increased this, up to 320W.
