This low-power, x86-64 architecture was designed by AMD to compete in the mobile and embedded space, offering a balance of performance and energy efficiency. The Jaguar architecture was a significant step forward from its predecessor, the Bobcat, featuring improvements in clock frequency and instructions per clock (IPC). It supported instruction sets like AVX and SSE4, making it capable of handling modern media applications.
The Jaguar architecture’s ability to support up to four independent cores, each with its own L1 cache and sharing a unified L2 cache, made it a versatile choice for system-on-chip (SoC) designs. Both the PlayStation 4 and the Xbox One utilized SoCs based on the Jaguar microarchitecture, with AMD equipping them with more powerful GPUs than were typically found in commercially available Jaguar APUs. This strategic use of the Jaguar architecture allowed for the creation of relatively compact and power-efficient consoles that could still deliver compelling gaming experiences. The PlayStation 4, for instance, featured an AMD APU with eight Jaguar cores clocked at 1.6 GHz and 18 compute units for its GPU, while the Xbox One also used an eight-core Jaguar APU, though clocked slightly higher at 1.75 GHz.
The Evolution of AMD’s Architecture: From “Zen” to Next-Generation Consoles
While the “Jaguar” architecture powered the initial wave of Steam Machines and current-generation consoles, AMD was already looking towards the future. The company’s “Zen” architecture, first launched in 2017, represented a significant leap forward in CPU design. “Zen” introduced a hybrid, multi-chip architecture that decoupled innovation paths, enabling AMD to deliver improved performance, scalability, and efficiency across its product lines. This architecture powered AMD’s Ryzen processors for desktops and mobile, as well as its EPYC processors for servers and Threadripper for workstations.
The “Zen” architecture’s focus on increasing per-core performance, with a targeted 40% improvement in instructions per cycle (IPC) over its predecessors, was achieved through a better core design, improved cache systems, and a focus on lower power consumption. Innovations such as Simultaneous Multithreading (SMT) allowed each core to process multiple threads, further enhancing processing throughput. The “Zen” architecture’s evolution, including “Zen+”, “Zen 2,” “Zen 3,” and “Zen 4,” has consistently pushed the envelope in terms of core counts, clock speeds, and efficiency, laying the groundwork for future console generations. The “Zen 2” architecture, for example, powers the PlayStation 5 and Xbox Series X/S, showcasing AMD’s continued dominance in the console market.
Next-Generation Xbox SoC: A Glimpse into the Future of Console Power
AMD’s role in console development extends beyond the current generation. The company has been a long-term partner with Microsoft for its Xbox consoles, and the update on the next-generation Xbox SoC was a key part of AMD’s announcement. This next-generation chip is expected to be significantly more powerful than its predecessors, leveraging AMD’s latest advancements in CPU and GPU technology. Microsoft’s “Project Scarlett,” later revealed as the Xbox Series X, was confirmed to run on an AMD chip and was projected to be four times as powerful as the Xbox One X.
