It's been a while since we last looked at something from Zotac, so when the company reached out and offered a review of the RTX 4070 Super Trinity Black Edition, you can bet we were keen to get hands on! Sporting a triple-fan cooler, curvaceous shroud design and Zotac's Spectra RGB lighting, today we find out what this card can do at the £619.99 asking price.

Having already reviewed RTX 4070 Super models from the likes of Gigabyte, Palit and Inno3D, today our attention turns to Zotac and the RTX 4070 Super Trinity Black Edition. Retailing for £619.99 here in the UK, we assess gaming performance, GPU and memory thermals, overclocking and more to find out if this card is worth the cash.

First, a quick spec recap. Just like the RTX 4070 Ti and RTX 4070, the new 4070 Super uses a cut-down AD104 die, measuring 295mm². The fundamental building blocks are still the same of course, with the RTX 4070 Super offering a total of 56 Streaming Multiprocessors (SMs), each housing 256 CUDA Cores, for a total of 7168. We also find 56 RT cores, 224 Tensor cores, 224 Texture Units, and 80 ROPs.

TSMC's N4 node has Nvidia cranking up the clock speed significantly this generation, with the RTX 4070 Super sporting the same 2475MHz rated boost clock as the original model. Zotac's Trinity Black model we are reviewing does not come factory overclocked.

The memory configuration also remains the same as both the 4070 and 4070 Ti. That means a relatively narrow 192-bit memory interface, so even with 12GB GDDR6X running at 21Gbps, total memory bandwidth comes in at 504 GB/s, lower than the RTX 3070 Ti. That said, there has been a substantial upgrade to the L2 cache with the Ada architecture, with the RTX 4070 now offering 49.1MB, compared to just 6MB for GA102.

Considering the increased core-count, power draw is naturally a touch higher than the RTX 4070, with the 4070 Super boasting a 220W TGP. Zotac has not increased this out of the box for the Trinity Black, though the power limit can be manually increased by 10% when overclocking.
