Compared to the release time, what is interesting is the new rumors of the Navi 24 core that this GPU will be manufactured using a 6nm process. Although it did not specify which foundry, it is likely to be TSMC, which means that Navi 24 will be manufactured using the same process as Intel’s first-generation Intel Arc Alchemist graphics card. Interestingly, there has been news in the past that AMD’s next-generation Radeon RX 7000 series will be composed of RDNA 2 and RDNA 3 architecture GPUs, of which RDNA 2 architecture GPUs will be manufactured using a 6nm process. The Navi 31/Navi 32/Navi 33 based on the RDNA 3 architecture is oriented to the mid-to-high-end market and will be manufactured using the 5nm process, while the mid-to-low-end market will have 6nm process products.
AMD Radeon RX 6500 XT and RX 6400 both use Navi 24 cores, equipped with 16MB infinite cache, 1MB L2 cache, and 128KB L1 cache. Radeon RX 6500 XT will be configured with 16 CUs and 1024 stream processors, while Radeon RX 6400 will have only 12 CUs and the number of stream processors will be 768. The two graphics cards will be equipped with 4GB of GDDR6 memory, and the memory width is 64 bits. The GDDR6 memory rates of Radeon RX 6500 XT and RX 6400 are rumored to be 16 Gbps and 14 Gbps, respectively, and the corresponding memory bandwidths are 128 GB/s and 112 GB/s. It is said that AMD will use the memory bandwidth with infinity cache, Radeon RX 6500 XT and RX 6400 will be nominally 232 GB/s, and 216 GB/s.
In terms of power consumption, Radeon RX 6500 XT and RX 6400 are 107W and 53W respectively. From the leaked renderings, we can see that the graphics card based on Navi 24 XT is a dual-slot specification and will have a 6Pin external power supply interface. The graphics card based on Navi 24 XL will be a single-slot half-height specification and does not require an external power supply. Both graphics cards will be equipped with two display output ports. Both graphics cards will be equipped with two display output ports, namely DisplayPort and HDMI. Regrettably, it is still unclear what the core frequency of Radeon RX 6500 XT and RX 6400 are. Previously, it was rumored that the core frequency of Navi 24 may be relatively high, even reaching 2.8 GHz or above.
