Radeon RX 6500XT and RX 6400 would be AMD's first 6nm GPUs

Thanks to the renders published by VideoCardz, we can take a first look at two new graphics cards based on AMD's Navi 24 6nm GPU: Radeon RX 6500 XT and Radeon RX 6400. Barring surprises, Navi 24 is expected to be the latest die in the RDNA2 family and presumably measures just 141mm², making it the smallest in the range. However, from a spec point of view, Navi 24 may have only 16 CUs for a total of 1,024 cores and will be accompanied by 16MB of Infinity Cache and a memory bus of just 64 bits.



For comparison, the Navi 23 die, which is currently featured on the Radeon RX 6600 and Radeon RX 6600 XT, is substantially larger (236mm²) and features twice the CU, along with four times the amount of Infinity Cache and a 128-bit memory bus. So we can expect any GPU equipped with the Navi 24 die to be at least twice as slow as a Radeon RX 6600 XT, if not more due to Infinity Cache's noticeable size reduction. However, the performance as such should be perfectly adequate for the entry-level market.

According to another VideoCardz article, the specifications of the Radeon RX 6500 XT see the presence of 1,024 core, 4 GB of 16Gb / s GDDR6 on a 64-bit bus and a power limit of 107 W. The Radeon RX 6400 features are slightly downsized compared to the RX 6500 XT, with only 768 cores and 4GB of 14-inch GDDR6 Gb / s. However, the power consumption of this card is only 53W, so we can easily see it in very low-end and compact systems.



We will most likely know more at CES 2022. However, only the Radeon RX 6400 XT will be available for the consumer market, while the Radeon RX 6400 will be an OEM product.
