Pretty dumb article as we know NOTHING about the new architecture or how Navi 51 CU's compare to Navi 48 CU's. Navi 48 CU's are about 50% faster than Navi 31 CU's, allowing the 9070XT's 64CU's to go head-to-head with Navi 31's 96CU's. Navi 51 could end 2x as fast as Navi 31. Hell, a 96 CU Navi 48 would kick the crap out of a 5080 and be faster than a 4090. Navi 51 should beat 5090 IMO if they can deliver another strong uplift like Navi 48.
Noted leaker Kepler_L2 has shed some light on AMD's upcoming RDNA 5/UDNA GPUs. Specs-wise, the flagship model will be identical to the Radeon RX 7900 XTX, with lower-end SKUs mirroring the 9070 XT and 9060 XT.
