Samsung users will soon enjoy an even faster GDDR6 memory as the company is now in the process of sampling 16Gb (2GB) memory modules that will be based on GDDR6 technology, having a bandwidth of 20Gbps (K4ZAF325BC-SC20) and 24Gbps (K4ZAF325BC-SC24) to its partners. @Olrak29_ has spotted that Samsung’s product catalog features the new modules. However, it does not give any hint on the use of these modules in retail products.
AMD Radeon RX 6000 series is primarily based on Samsung GDDR6 16Gbps memory, limited to the 256-bit memory bus.
The 24Gbps and 20Gbps modules could be supported by next-gen GPUs, such as those based on AMD RDNA3, as well as mid-range/mobile NVIDIA Lovelace processors. The 24Gbps memory brings into use the same “180FGBA ” package as the K4ZAF325BM-HC16 modules featured on, for instance, the RX 6900 XT.
It is rumored that the upcoming RTX 3090 Ti featuring 21 Gbps memory, will now be launched in late January. Radeon RX 6900 XT LC is AMD’s fastest GPU offering 18.5 Gbps modules.
