I agree with @Buildzoid1.

When referring to DRAM speed, best to use "Gbps" rather than "GT/s" although in the case of DDRx, they are the same. Avoid "MHz". It is quite simply, wrong.

I believe "GT/s" came about because "transfer rate" not always = "bitrate".

Example: PCIe 4.0 has a transfer rate of 16 GT/s but uses 128b/130b line encoding, so a x16 slot has an effective bandwidth of ~31.5 GB/s:

(16 GT/s * 16 lanes * 128/130) / 8 bits/Byte = 31.5077 GB/s.

It amazes me that so many people seem to think TSMC is some simple-minded "EVERYONE'S FOUNDRY", only interested in short term profit maximization.

Come on, think again. TSMC didn't get to where is today by being an opportunistic money grab, sans ability to think strategically. Modern fabs cost upwards of $10 billion apiece to build. ROI for capital equipment alone is many, many years, not to mention astronomical operating costs on an ongoing basis. If you don't keep those fabs full during it's entire lifetime, you'll go bankrupt pretty damn quick.
