AMD’s RDNA 3 range so far is good, but the pricing of the RX 7900 XT makes it an unlikely pick — it’s a far worse deal than the flagship RX 7900 XTX.

ASUS explains more: "Built on the 'Zen' 4 architecture combined with AMD RDNA 3 architecture-based graphics, the Ryzen Z1 Extreme processor rivals the prowess of game consoles with 8 cores, 16 threads, and up to 8.6 teraflops of graphics processing power.

Built on the RDNA 2.0 architecture and 8 GB of VRAM the RX 6600 XT offers excellent performance for a reasonable price.

For the sake of comparison, rumors place Intel’s second-gen “Battlemage” cards at a mid-2024 release, and AMD’s RDNA 4-based cards (RX 8000 series, presumably) aren’t expected before 2025.

However, the RDNA 3 chips don’t use a chiplet design like their desktop counterparts.

Obviously, that's a bit of an apples and orange comparison—the Radeon RX 6800 is based on AMD's previous-generation RDNA 2 graphics architecture whereas the GeForce RTX 4080 is a faster card based on NVIDIA's newest Ada Lovelace tech.

The first generation RDNA architecture-based Navi 10 GPUs did not have a high-end offering, unlike the latest Navi 31 and Navi 33 GPUs.
