AMD Radeon RX 7800 XT and RX 7700 XT launch today

September 6th marks an important date for AMD, as the company launches its third and the last Navi 3X GPU called Navi 32. This processor sits in the middle of the desktop Radeon RX 7000 stack and will be used by two models: RX 7800 XT and RX 7700 XT. 

AMD has set its sights on the high-end market with the aggressively (as said by AMD) priced cards of $499 and $449, taking direct aim at NVIDIA’s GeForce RTX 4070 ($599) and RTX 4060 Ti 16GB ($499). On paper and according to AMD’s benchmarks, the RX 7800/7700 duo boasts greater speed and affordability. But there might be more to this story that reviewers will look into.

The RX 7800 XT is equipped with the Navi 32 XT GPU, sporting 60 Compute Units (3840 Stream Processors). It fully leverages a multi-chip design incorporating 5nm GCD and 6nm MCD, with an 28.1 billion transistors, surpassing even Navi 21’s 26.8 billion. The RX 7800 XT boasts a 2124 MHz game clock and a 2430 MHz boost clock, though early information from board partners hints at clock increases in custom models.

Additionally, the RX 7800 XT features 16GB of GDDR6 memory clocked at 19.5 Gbps. Coupled with a 256-bit memory bus, this results in a maximum theoretical bandwidth of 624 GB/s, or 2708 GB/s when considering the 64MB Infinity Cache.

AMD’s RX 7700 XT employs the same GPU but with fewer enabled cores, specifically configured with 54 Compute Units (3454 Stream Processors). This model features a reduced memory capacity of 12GB GDDR6 on a 192-bit bus, also clocked lower than the Navi 32XT. It offers a memory speed of 18 Gbps and a bandwidth of 432 GB/s (1995 GB/s with Infinity Cache).

As previously mentioned, the Radeon RX 7700 XT will not be available with AMD’s MBA (Made by AMD) cooler design. Instead, it will launch exclusively as a partner SKU. In contrast, the RX 7800 XT will debut with the MBA design and should be accessible through AMD’s official distribution channels.
