ZM-88 vs 521 specifications comparison

The charts below compare the most important Intel 521 and ZM-88 characteristics. These features, along with an IPC (instructions per cycle) number, determine how well a microprocessor performs. The "Number of cores / threads" graph displays the number of cores (darker area). Lighter area on the graph represents the number of extra threads, offered by Hyper-Threading technology. Darker area on the "On-chip cache" graph is for the On-chip L1 cache. Lighter area is for the L2 cache cache. While the L2 cache cache is usually larger than the On-chip L1 cache, it is always slower.
