Xbox 360 and Xbox Original
📌CPU: The original Xbox relied on popular off-the-shelf stock (Intel’s Pentium III) with slight customizations. This was a single-core CPU extended with vectorized instructions and a sophisticated cache design. On the other hand, the Xbox 360 introduced a new type of CPU that was unlike anything seen on the store shelves. This was a multi-core processor developed by IBM, reflecting an obsessive need for innovation characteristic of the 7th generation of consoles
📌GPU: The original Xbox’s GPU was based on the NV20 architecture, with some modifications to work in a unified memory architecture (UMA) environment. The Xbox 360, however, used a semi-customized version of Direct3D 9 for its GPU, called Xenos
📌Memory: The original Xbox included a total of 64 MiB of DDR SDRAM, which was shared across all components of the system. The Xbox 360, on the other hand, had a unified memory architecture with 512 MB of GDDR3 RAM
📌Development Ecosystem: The original Xbox was designed with familiarities appreciated by developers and online services welcomed by users. The Xbox 360, however, was designed with an emphasis on the emerging 'multi-core' processor and unorthodox symbiosis between components, which enabled engineers to tackle unsolvable challenges with cost-effective solutions
📌Release Timing: The Xbox 360 was released a year before its main competitor, the PlayStation 3, and was already claiming technological superiority against the yet-to-be-seen PlayStation 3
PS2 and PS3:
📌CPU: The PS2's Emotion Engine was designed by Toshiba, using MIPS technology, and focused on achieving acceptable 3D performance at a reduced cost. In contrast, the PS3's CPU, the Cell Broadband Engine, was developed through a collaboration between Sony, IBM, and Toshiba, and is a highly complex and innovative processor that intersects complex needs and unusual solutions
📌GPU: The PS2's GPU, the Graphics Synthesizer, was a fixed-functionality GPU designed for 3D performance. The PS3's GPU, the Reality Synthesizer (RSX), was manufactured by Nvidia and was designed to offload part of the graphics pipeline, offering better parallel processing capabilities
📌Memory: The PS2 had 32 MB of RDRAM, while the PS3 had a more advanced memory system, with 256 MB of XDR DRAM for the CPU and 256 MB of GDDR3 RAM for the GPU.
📌Development Ecosystem: The PS2's development ecosystem was based on MIPS technology and focused on achieving acceptable 3D performance at a reduced cost. The PS3's development ecosystem was more complex, involving collaboration between Sony, IBM, and Toshiba, and focused on creating a powerful and innovative system
