Durable Incrementality

Plotting instruction counts shows just how severe the situation can get for Cortex X925. 507.cactuBSSN, 521.wrf, 549.fotonik3d, and 554.roms all require more instructions on X925, and by no small margin. 554.roms is the worst offender, and makes X925 execute more than twice as many instructions compared to Zen 5. Average IPC in these four tests is nowhere near core width for any of these tested cores, but crunching through extra instructions isn’t the only issue. Higher instruction counts place more pressure on core out-of-order resources, impacting its ability to hide latency.
“We want to be exactly where new businesses are created,” quips Baronchelli. “This represents the biggest opportunity for us—businesses that want to try new things, that are early adopters of technology—we want to be close to them.”
