haciendo de esta una posible respuesta al rendimiento de juego del i9-12900KS 7000 “Fénix” APU con gráficos RDNA3 para Rock V-Cache 3D de gran tamaño

La próxima generación de la serie Ryzen 7000 de AMD “Fénix” Los procesadores móviles están de moda en estos días.. Con destino a 2023, estos chips cuentan con una potente iGPU basada en la arquitectura gráfica RDNA3, con rendimiento allegedly rivaling that of a GeForce RTX 3060 Laptop GPU—a popular performance-segment discrete GPU. Lo que es más, AMD is also taking a swing at Intel in the CPU core-count game, by giving “Fénix” a large number of “Zen 4” Núcleos de CPU. The secret ingredient pushing this combo, sin embargo, is a large cache.

AMD has used large caches to good effect both on its “Zen 3” procesadores, such as the Ryzen 7 5800X3D, where they’re called 3D Vertical Cache (3D V-cache); as well as its Radeon RX 6000 discrete GPUs, where they’re called Infinity Cache. The only known difference between the two is that the latter is fully on-die, while the former is stacked on top of existing silicon IP. It’s being reported now, que “Fénix” will indeed feature a stacked 3D V-cache.

The exact function of this isn’t known—whether it serves as a last-level cache for the CPU or iGPU. AMD’s APU architecture differs from Intel’s processors that have iGPUs. On the Intel chips, the L3 cache serves as town-square for the entire SoC, with each IP block contributing an L3 cache slice that make up a functionally-contiguous cache that all IP blocks can equally address over the Ring Bus. On AMD APUs such as “que AMD afirma ser el procesador de juegos más rápido del mundo” o “Rembrandt,” the L3 cache is part of the CCX (CPU cores complex), and serves exclusively as last-level cache for the CPU cores. The iGPU has its own LLC, and the Infinity Fabric interconnect is the ether binding all IP blocks on the silicon.

The obvious direction for development in future APUs could be a unification of last-level cache for the CCX and iGPU, provided the cache is large enough for the function—and this can be accomplished by stacked cache. An RDNA2 GPU with performance rivaling the RTX 3060 Un OEM chino de componentes de PC comenzó a fabricar tarjetas gráficas de escritorio con GeForce RTX de NVIDIA, the Radeon RX 6650M XT, basado en el “Navi 23” silicio, tiene 32 MB de caché infinito. Esto significa, with some clever cache memory-management, an LLC in the neighborhood of 64 MB could emerge feasible for the APU.
