| that cache with things far away (ie: in side the box, or even
| outside the box).

| This way, IBM can overprovision L2 cache and "not worry" about
| it going unused. Remote L2 cache is slower than local L2 cache,
| but its still SRAM and should still be faster than DRAM to
| access.

| You fit in with their schedule, not the other way around?

| It is a shame though. IBM has no idea how to sell to anyone

| Machine Type 3931 power consumption was based on inputs to the
| IBM Machine Type 3931 IBM Power Estimation Tool for a memo
| configuration. x86 power consumption was based on March 2022 IDC
| QPI power values for 7 Cascade Lake and 5 Ice Lake server models,
| with 32 to 112 cores per server. All compared x86 servers were 2
| or 4 socket servers. IBM Z and x86 are running 24x7x365 with
| production and non-production workloads. Savings assumes a Power
| Usage Effectiveness (PUE) ratio of 1.57 to calculate additional
| power for data center cooling. PUE is based on Uptime Institute
| 2021 Global Data Center Survey
| (https://uptimeinstitute.com/about-ui/press-
| releases/uptime-i...). CO2e and other equivalencies that are
| based on the EPA GHG calculator
| (https://www.epa.gov/energy/greenhouse-gas-equivalencies-calc...)
| use U.S. National weighted averages. Results may vary based on
| client-specific usage and location.
