Seasonic has leaked the AMD Radeon RX 8800 XT power target, showing a much more efficient chip and widely used power connectors. This mid-range RDNA 4 GPU could make for a nice drop-in upgrade.
According to Seasonic’s wattage calculator, the upcoming RX 8800 XT graphics card will target a 220W TDP. This puts it between RX 7600 XT at 190W and RX 7700 XT at 245W, while offering much more performance if we believe the latest rumours. Against Nvidia, RX 8800 XT ends up identical to RTX 4070 Super at 220W, which is encouraging to say the least.
Radeon RX 8800 XT is expected to deliver performance around that of an RTX 4080 or RTX 4080 Super, resulting in some astounding figures if the wattage ends up true to market. Using Cyberpunk 2077 to measure, AMD’s upcoming card clocks in at around 31% more efficient than RTX 4080 Super.
On one hand, this marks a nice generational uplift, but on the other, RTX 4080 Super will soon be considered last-gen. Thus, putting the RX 8800 XT against a hypothetical RTX 5070 / RTX 5060 Ti seems much fairer. In this case, Nvidia only needs to improve efficiency slightly to claim the win in this department.
But again, this is pure speculation based on rumoured performance targets, not even considering each architecture’s affinity with technologies such as ray tracing and path tracing. More importantly, we don’t know how this 220W TDP is calculated let alone the accuracy of comparing it to another brand altogether. That said, the difference between a reported 220W on an Nvidia card and an AMD card is unlikely to be extremely different.
The calculator also indicates that this card will be powered via two 8-pin cables instead of the newer 12V-2×6. This means better compatibility with existing machines/PSUs, which is important for those who plan to upgrade their current rigs.
All in all, a promising view of next-gen hardware even though this may be a simple typing error from Seasonic. As things stand, RX 8800 XT is said to feature the Navi 48 GPU packing 56 RDNA 4 compute units and 16GB of GDDR6 memory. Luckily we don’t have long to wait, as AMD is expected to unveil Radeon 8000 in January.
