Following our launch-day review of AMD's RX 9070 XT, today it's PowerColor's turn as we assess the Red Devil custom card. Designed to offer a high-end experience, this card comes with a 3060MHz factory overclock, a triple-slot, triple-fan cooler, and it also requires three PCIe 8-pin power connectors. Let's put it through its paces and find out just how good this card is.

At the time of writing we don't have a confirmed UK MSRP from PowerColor for the RX 9070 XT Red Devil, however it is listed for £720 from both Scan and Overclockers UK – putting it in very similar territory to the Sapphire RX 9070 XT Nitro+.

First, let's take a quick look at the specs. The RX 9070 XT is built on the new Navi 48 die, measuring 357mm², and it's worth pointing out this is a monolithic chip, so AMD is not using a chiplet-based design as per RDNA 3. In total, Navi 48 silicon packs in 53.9 billion transistors.

As a full implementation of Navi 48, the RX 9070 XT packs in 64 Compute Units, and each CU houses 64 Stream Processors, for a total of 4096 shaders. There's also 64 Ray Accelerators – one per CU – and 128 ROPs.

As for clock speed, the RX 9070 XT runs notably faster than its sibling, the RX 9070, given it sports a rated game clock of 2400MHz and a boost clock of up to 2970MHz. PowerColor has increased things further however, with a rated boost of 3060MHz.

The memory configuration is the same between both GPUs though, with 16GB of GDDR6 memory clocked at 20Gbps, operating over a 256-bit memory interface, for total memory bandwidth of 645 GB/s. 64MB of Infinity Cache is also present.

Power draw for the RX 9070 XT is rated at 304W Total Board Power (TBP), PowerColor has increased this up to 330W.
