If we are to believe what Jim Keller, Intel's senior vice president for technology and system architecture, has shared with the world, his company is currently working on a fundamentally new microarchitecture that is expected to be \"significantly larger and closer to a linear performance dependence on the number of transistors\" than the current Sunny Cove design. This seems to suggest that in a few years, we will have a processor that is significantly more complex and much more powerful than the CPUs that the microprocessor giant offers today.<\/p>\n

The new Sunny Cove microarchitecture used by Intel in the new Ice Lake generation processors has been a significant breakthrough, as it noticeably raised the IPC (instructions per clock cycle) after quite a long hiatus. However, processor guru Jim Keller, who currently works at Intel, states that this is far from being the final point. He is now working on the next generation of microarchitecture that will fully utilize the expected multiple increases in transistor budgets over the next few years.<\/p>\n

\"Jim<\/p>\n

According to Intel's estimates, the advantage of Sunny Cove cores over Coffee Lake cores in specific performance reaches 15\u201318% (at the same clock frequency). However, the transistor budget for Sunny Cove exceeds that of its predecessor by a significantly larger amount \u2014 around 38%. According to information revealed by Keller, a core with Sunny Cove microarchitecture consists of approximately 300 million 10-nm transistors, while the Coffee Lake core contains about 217 million 14-nm transistors. Thus, the performance increase in Sunny Cove does not reach a linear relationship with the transistor budget: the progress in performance turned out to be about half of the increase in the complexity of the semiconductor die. According to Keller, this should not be the case.<\/p>\n

During a lecture at the University of Berkeley, a leading specialist from Intel touched upon the evolution of Intel's processor microarchitectures and, in the discussion, did not stop at Sunny Cove but mentioned a possible successor to this microarchitecture: \"Sunny Cove operates with 800 instructions simultaneously, executing from 3 to 6 x86 instructions per cycle\u2026 It has massive data predictors, massive branch predictors. But we are working on a generation of microarchitecture that is significantly larger and the law of performance growth is closer to linear. This is indeed a serious shift in thinking.\"<\/p>\n

<\/center><\/p>\n

Stjerneingeni\u00f8rens rolle er, at processorteknologi stadig er langt fra at n\u00e5 et vist gr\u00e6nsepunkt. Som Keller siger, har Intel store planer for fremtiden, herunder en 50-dobling af antallet af transistorer i processorerne samt betydelige forbedringer i n\u00e6sten hver funktionel enhed. Og der er intet umuligt i dette. Som Keller forklarer: \"Computere skabes af en stor gruppe mennesker, men i virkeligheden er det en lang r\u00e6kke sm\u00e5 teams. Man kan forbedre forudsigelser af overgange, instruktioner, arkitektur, optimere, bruge mere avancerede designv\u00e6rkt\u00f8jer og bedre biblioteker. Antallet af forskellige anvendelsesomr\u00e5der, hvor der er plads til innovation, er faktisk meget stort.\"<\/p>\n

\"Jim<\/p>\n

De nuv\u00e6rende offentlige planer fra Intel omfatter to iterationer af forbedring af mikroarkitekturen efter Sunny Cove. I det n\u00e6ste design, Willow Cove, burde der som lovet ske \u00e6ndringer i cache-subsystemet og overgangen til en ny halvlederteknologi (formentlig 7 nm). Derefter i Golden Cove vil den enekernede ydeevne blive forbedret, og fokuset vil v\u00e6re p\u00e5 opgaver inden for kunstig intelligens sammen med de n\u00f8dvendige optimeringer for bedre ydeevne i 5G-netv\u00e6rk. Det er muligt, at Jim Keller i sin pr\u00e6sentation netop mente Golden Cove, selvom der ikke blev sagt noget konkret om dette.<\/p>\n
