Sony and AMD formally announced "Project Amethyst," their collaboration to develop machine-learning technology to improve graphics and gameplay, in 2024. The partnership has already benefitted both companies: Cerny says Sony contributed to the development of AMD's FSR 4 and similar improvements are now trickling back to the PS5 Pro. Both companies' plans to improve everything from upscaling performance to energy efficiency could also pay further dividends in future consoles and GPUs.
但真正的问题是,理想模型往往建立在需求高峰与利用率饱和的假设之上。而真实世界中的利用率,从来不会长期维持在高位。

Under load, this creates GC pressure that can devastate throughput. The JavaScript engine spends significant time collecting short-lived objects instead of doing useful work. Latency becomes unpredictable as GC pauses interrupt request handling. I've seen SSR workloads where garbage collection accounts for a substantial portion (up to and beyond 50%) of total CPU time per request. That's time that could be spent actually rendering content.
Ongoing improvements of our rendering infrastructure will help ensure that that is the case.
