- Leadin: To help improve memory bandwidth, a cache now sits between the processor and memory that services vector operations as well as scalar.
- -The key information to note here is the bandwidth. While main memory to cache was 2.5 gb/s (3.2 theoretical) bandwitdh from cache to cpu is 9.6 gb/s.
- -You can see potentially significant increases in memory bandwidth if the data you need resides in cache
- -Some other important things that have performance implications are….
