Although I'm a long time Qualcomm Snapdragon loyalist, I'm very grateful for the great powerful chips Media Tek produces such as the Dimensity 9500 because it forces Qualcomm to produce their best chip and the battle between Snapdragon 8 Elite Gen 5 vs Dimensity 9500 should be very competitive with no clear winners since the differences in performance benchmarks should be miniscule just as it's been for over 3 years now.
An X user has posted a die shot of the MediaTek Dimensity 9500. At 140.79 mm2, the chip is measurably larger than the Dimensity 9400, which measured ~126.26 mm2.
