AMD's upcoming Radeon RX 8000 series GPUs based on RDNA 4 architecture are just around the corner, with rumors pointing to a CES unveiling event. Today, we are learning that the Radeon RX 8800 XT GPU will feature a 220 W TDP, compared to its Radeon RX 7800 XT predecessor with 263 W TDP, thanks to the Seasonic wattage calculator. While we expect to see better nodes used for making RNDA 4, the efficiency gains stem primarily from the improved microarchitectural design of the new RDNA generation. The RX 8800 XT will bring better performance while lowering power consumption by 16%. While no concrete official figures are known about RNDA 4 performance targets compared to RDNA, if AMD plans to maintain the competitive mid-range landscape with NVIDIA "Blackwell" and, as of today, Intel with Arc "Battlemage," team red must put out a good fight to remain competitive.

We reported on AMD Radeon RX 8800 XT entering mass production this month, with notable silicon design a departure from previous designs. The RX 8800 XT will reportedly utilize a monolithic chip dubbed "Navi 48," moving away from the chiplet-based approach seen in the current "Navi 31" and "Navi 32" GPUs. Perhaps most intriguing are claims about the card's ray tracing capabilities. Sources suggest the RX 8800 XT will match the NVIDIA GeForce RTX 4080/4080 SUPER in raster performance while having a remarkable 45% improvement over the current flagship RX 7900 XTX in ray tracing. However, these claims must be backed by independent testing first, as performance improvements depend on the specific case, like games optimized for either AMD or NVIDIA yield better results for the favorable graphics card.
 
If AMD can keep the price down with comparable performance to an RTX4080 I think AMD will have a winner. Hopefully we'll find out next month.
