O2 CPUs
Benefits of CPU Designs:
-
R5000: High-performance concurrent floating
point and integer operations; Streamlined 3D geometry calculations with
multiply/add instructions; Large, fast, on-chip caches.
-
R10000: Supercomputer performance for applications demanding high levels of processing capabilities and large
3D models; Bottleneck elimination: out-of-order
execution & branch prediction; High-bandwidth, non-blocking cache system
reduces memory latency for maximized application performance.
