RTX 5090 vs RX 7900 XTX

AMD Radeon RX 7900 XTX uses RDNA 3 chiplet architecture, while the NVIDIA GeForce RTX 5090 is based on the Blackwell architecture with a custom 4nm TSMC process

RTX 5090 features a massive 24,576 CUDA cores, 170+ RT cores, and 680+ Tensor cores, compared to 6,144 stream processors, 96 ray accelerators, and 192 AI accelerators on the RX 7900 XTX

RX 7900 XTX offers 24GB GDDR6 memory (384-bit, 960 GB/s), while the RTX 5090 boasts 32GB GDDR7 (512-bit, 1792 GB/s) for higher bandwidth and future-proofing

The RX 7900 XTX supports DisplayPort 2.1 for next-gen displays, while the RTX 5090 uses DisplayPort 1.4a and HDMI 2.1a

RTX 5090 excels in ray tracing and AI workloads, with DLSS 4, frame generation, and advanced path tracing, while RX 7900 XTX’s ray tracing and FSR 2.x/3 are less effective

Gaming performance: RX 7900 XTX rivals the RTX 4080 in 4K rasterization, but RTX 5090 dominates in 4K/8K gaming, especially with ray tracing and DLSS 4 enabled

RX 7900 XTX is more power efficient (355W TDP) and compact (triple-fan, 2.5-slot), while RTX 5090 draws 575W and is expected to be a quad-slot card
