Best for rate tracingBest for gaming value proposition
Pros
Claims to be 37% faster on average than the RX 7900 GR for raster titles
Reports an average uplift of 53% for ray tracing examples, suggesting a larger boost in this area compared to rasterization
The inclusion of FSR 4 is noted as a potential benefit
It provides performance close to the RTX 4070 Super in worst-case scenarios and potentially near the RTX 4070 Ti levels for ray tracing.
Cons
Reviewers suggest it may lack a 'wow factor' or major architectural improvements.
Its price point, especially when compared to NVIDA's pricing models, might make it difficult to justify an upgrade for certain users.
It is predicted to fall considerably short of the RTX 3070 Ti in some estimates.
