SI-42 vs i3-3250T specifications comparison

The charts below demonstrate the difference between Intel i3-3250T and AMD Mobile Sempron SI-42 most important characteristics. These features, together with an IPC (instructions per cycle) number, determine how well a CPU performs. The "Number of cores / threads" graph displays the number of cores (darker area). Lighter area on the graph represents the number of additional threads, offered by Hyper-Threading technology. Darker area on the "On-chip cache" graph is for the On-chip L2 cache. Lighter area is for the L3 cache cache. Although the L3 cache cache is usually larger than the On-chip L2 cache, it is always slower.

CPUIDs

The table below compares support for x86 extensions and technologies, as well as individual instructions and low-level features of the AMD Mobile Sempron SI-42 and Intel Core i3-3250T microprocessors. Information in this table was retrieved from actual processors using CPUID instruction, and we also utilized internal timer to measure CPU frequency. Be aware that all technologies, disabled in BIOS or by a virtual machine, will be shown as not supported. Different steppings of Intel processors may also have slightly different features. In rare cases, measured frequency may differ from official specifications.
