Sapphire Radeon RX 6400 Pulse revealed

At the CES 2022 exhibition, AMD released the Radeon RX 6500 XT/RX 6400 based on the RDNA2 architecture, with 16 and 12 CUs, or 1024 and 768 stream processors, respectively. The Radeon RX 6500 XT is already on sale, and according to AMD, the Radeon RX 6400 should be limited to the OEM market.

However, with the changes in the market, the Radeon RX 6400 seems to be no longer limited to the OEM market, but also to the DIY market. Previously, ASRock submitted a new document to the Eurasian Economic Commission (EEC), which included an ITX specification graphics card called “RX6400 CLI 4G”. Sapphire, one of AMD’s major AIB vendors, will also launch an entry-level graphics card called the Radeon RX 6400 Pulse, according to VideoCardz.

Compared with ASRock’s Radeon RX 6400, Sapphire’s product is more compact, with a single-slot half-height structure, equipped with a DisplayPort 1.4 port and an HDMI 2.1 port, and the single-fan configuration is enough to meet its 53W power dissipation. Its overall shape is very similar to the Radeon Pro W6400 released by AMD at the beginning of this year. The Navi 24 core it is equipped with is manufactured with a 6nm process, equipped with 16MB of infinite cache, equipped with 4GB of GDDR6 video memory, and the video memory bit width is 64 bits.

It is understood that AMD will start selling the Radeon RX 6400 graphics card for the DIY market on April 20. According to the previously exposed benchmark results, the Vulkan score of the Radeon RX 6400 is only 7% lower than the Radeon RX 6500 XT, but the OpenCL score is nearly 30% lower.
In addition, the PCIe 4.0 interface of the Radeon RX 6400 is the same as the Radeon RX 6500 XT, which is only four channels, plus it does not support 4K H.264/H.265 encoding and AV1 decoding.
