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 Palit JetStream OC, but we also have a review of the Gigabyte Aero OC if you are interested. The JetStream is a simple, no frills design that eschews RGB lighting and added extras in favour of a simpler approach. Let's find out just how good it is.

Unlike many other custom cards, Palit's RTX 4070 Super favours a simple design approach. It's entirely black, with a triple-slot triple-fan cooler, no RGB lighting or LEDs or any kind, no on-board fan headers, no included accessories or any other real features – it's very much just a heatsink and a PCB attached via some screws. That's not necessarily a bad thing though, and it could well appeal to those looking for a ‘set and forget' experience.

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 reference RTX 4070 Super sporting the same 2475MHz rated boost clock as the original model. Palit has bumped this up a fair amount with the JetStream OC however, with a rated boost clock of 2640MHz.

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 reference 4070 Super boasting a 220W TGP. Palit has increased this further though, this time with a 240W TGP for the JetStream OC.
