Following on from our review of Nvidia's RTX 4070 Super Founders Edition yesterday, today we can present reviews of two partner cards. This article is focused on the Gigabyte Aero OC, but we also have a review of the Palit JetStream OC if you are interested. The Aero OC is a beautiful white graphics card, complete with a triple-fan cooler, silver metal backplate and a hint of RGB lighting. Let's find out if the beauty is only skin deep…
Alongside the triple-slot, triple-fan cooler, the Aero OC also comes with a mild factory overclock, support for dual-BIOS, as well as a power limit that can be increased all the way to 320W. Combine that with the aesthetic and it certainly looks like an attractive card on paper, so let's see if it does enough to justify the £659.99 MSRP…

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. Gigabyte has increased this slightly, with the Aero OC offering a 2565MHz boost.
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. Gigabyte has not increased this out of the box for the Aero OC, but the power limit can be manually pushed up to 320W.
