Samsung GDDR6 memory is about to get faster

New memory for next-gen Radeon GPUs?

Samsung is now sampling 16Gb (2GB) memory modules based on GDDR6 technology with a bandwidth of 20Gbps (K4ZAF325BC-SC20) and 24Gbps (K4ZAF325BC-SC24) to its partners. The new modules have appeared in Samsung’s product catalog, as spotted by @Olrak29_. What the catalog does not confirm is how soon will such modules be used in retail products, such as next-gen graphics cards.

AMD Radeon RX 6000 series now mainly use Samsung GDDR6 16Gbps memory, limited to the 256-bit memory bus. If it wasn’t for the innovative Infinity Cache, the Radeon cards could have problems keeping up with bandwidth offered by NVIDIA RTX 30 GDDR6X memory, going up to 19.5 Gbps/384-bit on select models.

The 20Gbps and 24Gbps modules could be used by next-gen GPUs, such as AMD RDNA3-based, but also mid-range/mobile NVIDIA Lovelace processors. The 24Gbps memory uses the same “180FGBA” package as K4ZAF325BM-HC16 modules featured on, for instance, the RX 6900 XT.

NVIDIA might, however, be the first with a 20Gbps+ graphics card to the market, as the rumors point towards the upcoming RTX 3090 Ti featuring 21 Gbps memory, now set to debut in late January. AMD’s fastest GPU with GDDR6 memory is Radeon RX 6900 XT LC offering 18.5 Gbps modules.
