Threadripper’s 4 die variant had to be “neutered” to remain compatible with the TR4 socket without splitting memory bandwidth. The new I/O chiplet would solve that issue entirely, assuming it comes to Threadripper 3.
- bpye 8y agoI was just thinking this. Yes it'll have half the lanes of EPYC still, okay, but now the lanes will be connected to all the dies equally rather than to just 1/2 the dies. This hopefully means Threadripper 3 can perform almost as well as EPYC with just 1/2 the memory bandwidth - that isn't insignificant but it's a big improvement on Threadripper 2.
- Tuna-Fish 8y agoAn interesting point is that TR owners are much more likely to run their RAM at higher, out of JEDEC spec speeds, so the difference can be a lot smaller than 1/2.
