A quick tour of the RX 7900 GRE customs!


The RX 7900 GRE has just arrived on the global market, and AMD’s partner manufacturers have of course come up with their own customized versions. So let’s take a look at what they’ve come up with!

The RX 7900 GRE from Sapphire :

As far as Sapphire is concerned, we find three cards with the Nitro , Pure and Pulse models. While the Nitro looks like a top-of-the-range model, with its three fans and three slots, the Pulse and Pure models pale into insignificance. This is reflected in the following frequencies:

  • Nitro: boost to 2391 MHz
  • Pure: 2333 MHz
  • Pulse: 2290 MHz

In all cases, these boards will require a dual 8-pin PCIe power connector.

PowerColor: three cards!

PowerColor also offers a total of three cards. Here, clearly, the entry-level model is the Fighter version, which benefits from a double-slot heatsink topped by three fans. Here, the card will run at 2293 MHz boost, a little more than Sapphire’s Pulse version.

As for the Hellhound, we’re moving upmarket with lighting on the fans, while the heatsink is more imposing: 2.5 slot. Frequencies also increase here, with 2366 MHz.

Finally, the top of the range is represented by the Red Devil version, also equipped with a 2.5-slot, three-fan heatsink. However, we’ve learned that the board features a seven-heat-pipe heatsink and a PCB with 11 2 1 2 1 power supply phases, where other versions have fewer phases and less well-equipped heatsinks. Here, the boost frequency reaches 2391 MHz.

Two boards for ASUS!

From ASUS, we’re down to two boards: the RX 7900 GRE Dual and the TUF Gaming. Here, it’s easy to see which card is at the top of the range and which is at the entry level.

Naturally, the TUF model will be the spearhead of this model. It’s an imposing 2.5 slot card, with a length of ~32 cm. The cooling system comprises three Axial-Tech fans blowing over a double block of aluminum fins crossed by five copper heat pipes. All this enables the brand to offer a factory OC model at 2391 MHz boost.

On the small Dual side, we find a wiser card with just two fans and a footprint slightly larger than two slots. Length is also increased to ~28 cm. By default, we have a factory OC card with a frequency of 2293 MHz, which can be boosted to 2366 MHz via OC mode.

Challenger and Steel Legend versions from ASRock!

From ASRock comes a small Challenger version with a compact heatsink. This will benefit from a fairly basic cooling system with two fans. Overclocking is also standard, with a boost to 2293 MHz.

The Steel Legend model features a more elaborate heatsink, with a wide nickel-plated copper base for GPU and memory cooling. The heatsink is also topped by three axial fans with aRGB lighting, while a steel frame reinforces the PCB. Here, we can count on a boost frequency of 2333 MHz!

Just one Gigabyte model:

RX 7900 GRE Gaming OCWith this card, Gigabyte offers us its only model, along with the Gaming OC version. The board benefits from a three-fan cooling system, with a large network of aluminum fins crossed by seven copper heat pipes. Finally, a large copper base acts as a compact housing for the memory and GPU. Once again, beware of the footprint: 30 cm long and more than two slots.

Last but not least, its boost frequency of 2391 MHz rivals that of Sapphire’s Nitro or PowerColor’s Red Devil!
