AMD’s upcoming duo of RDNA 2 graphics cards, the Radeon RX 6500 XT and Radeon RX 6400, are supposedly the first to be built on a 6-nanometer process technology.
This is according to a source with VideoCardz, which suggests that the Radeon RX 6500 XT and Radeon RX 6400 are likely being manufactured on TSMC’s N6, a process that the company has said offers 18 percent higher logic density versus N7 (first-gen 7 nm). Current Radeon RX 6000 Series products are built on TSMC’s N7 process.
“For its Navi 24 SKUs, AMD is introducing a new (marketing) specs metric, which is Memory Bandwidth with Infinity Cache,” VideoCardz wrote regarding the new budget options. “According to official specs, the RX 6500 XT has 232 GB/s and RX 6400 has 216 GB/s. Those figures without Infinity Cache would (probably) be 128 GB/s and 112 GB/s respectively. This also implies that RX 6500 XT has 16Gbps GDDR6 memory while RX 6400 comes with 14 Gbps modules.”
The source also claims that AMD’s Radeon RX 6400 will be available exclusively from OEMs; AIB partners won’t be involved with the card. Both the Radeon RX 6500 XT and Radeon RX 6400 are expected to be announced during AMD’s CES 2022 press conference.
