IBM doubles its 14nm EDRAM density, adds hundreds of megabytes of cache

Twelve point two billion transistors. That's absolutely nuts. Does anyone have a ballpark figure for how much a 'drawer' of four of these things costs? What's it supposed to run, is this an Oracle/DB2 beast?

There is a version of DB2 for mainframe, but it’s a totally different codebase as I understand it. The operating system on a mainframe provides a lot of what modern app developers get from their database and caching systems, generally with better fault tolerance and availability. So if you have an app built for mainframe, it often will not have an external database dependency. Doing transactions can just look like writing to memory or files.

When I was running Z for Linux the costing was in the order of six figures per processor.

Nobody's even mentioned Crysis.

My impression is that RDBMS workloads are generally far more IO-intensive than CPU-intensive.

Looking at my own Azure SQL CPU vs IO vs Log charts right now, even with some CPU-heavy OLAP queries barely passes 25% CPU in the 2 vCore-sized database used in my current main project.

Wouldn't a DB benefit enormously from faster memory access? Perhaps you're only getting 25% CPU usage because the CPU is stalled waiting for main memory to reply...

An EPYC processor with 64 cores contains 40 billion transistors spread over 8+1 dies.

The cost will decrease over time, just like all tech.
