Further details regarding the die sizes, clock speeds, & PCIe Gen 4 connectivity for AMD Radeon RX 6600 series graphics cards based on the Navi 23 RDNA 2 GPU have been leaked by Igor's Lab.

We have already seen the specifications of the Navi 23 RDNA 2 GPU powered AMD Radeon RX 6600 XT and Radeon RX 6600 graphics cards leak out last week. The new details shed light on the die size and clock speeds of the graphics cards. The source states that the Navi 23 GPU will feature a 35x35 mm package size while the die will measure at 235.76mm2. This is just slightly smaller than AMD's Navi 10 GPU which measured at 251mm2. This is to incorporate a range of new technologies such as Infinity Cache, PCIe Gen 4 interface, & slightly larger cores with HW-accelerated ray-tracing tech.
