Hello,
I'm under the impression that DRAM Read\Write Bandwidth should be reported in GB/s (gigabytes per second) and not Gbps (gigabits per second).
Here's my loaded DDR5 4800 as it runs Llama3, a workload which I know is bottlenecked by DRAM bandwidth (see attachment).
If I read that as 40GB\s peak, then it's in line with what I read here about the maximums:

Here's another source:

Those 40GB\s that HWiNFO reads, would be 5 gigabytes/s if it were actually 40 gigabits per second (as stated from the program). If that'd be the case, my workload would be crawling to an halt, whereas it's pushing fast near the expected DDR5 4800 bandwidth performance.
I hope this triggers a double check on your side, thanks.

DDR5 RAM: Everything You Need to Know
DDR5 RAM, the successor to DDR4 memory, is the fifth-generation double data rate (DDR) SDRAM and the improvements are the greatest yet.
