At the heart of the M5 Pro and M5 Max are what Apple is calling a new “Fusion Architecture” that “combines two dies into a single system on a chip (SoC).” The chips both feature a new 18-core CPU, six of which Apple is now calling “super cores, that are the word’s fastest CPU core.”
Torsten Slok, the influential chief economist at Apollo Global Management, wrote in his Daily Spark on Saturday: “The dramatic change in recent weeks in the narrative in markets from ‘The economy is strong’ to ‘We are all becoming unemployed’ is truly remarkable.” He argued that markets are beginning to believe the view of “techno-optimists” about AI’s productive capabilities over the consensus of the Federal Reserve and economists.

Cortex X925 has a 64 KB L1 data cache with 4 cycle latency like A725 companions in GB10, but takes advantage of its larger power and area budget to make that capacity go further. It uses a more sophisticated re-reference interval prediction (RRIP) replacement policy rather than the pseudo-LRU policy used on A725. Bandwidth is higher too. Arm’s technical reference manual says the L1D has “4x128-bit read paths and 4x128-bit write paths”. Sustaining more than two stores per cycle is impossible because the core only has two store-capable AGUs. Loads can use all four AGUs, and can achieve 64B/cycle from the L1 data cache. That’s competitive against many AVX2-capable x86-64 CPUs from a few generations ago. However, more recent Intel and AMD cores can use their wider vector width and faster clocks to achieve much higher L1D bandwidth, even if they also have four AGUs.。关于这个话题，爱思助手下载最新版本提供了深入分析
