Q8400 vs i3-2130 estimated performance

The charts in the section below show relative performance of Core 2 Quad Q8400 and Core i3-2130 microprocessors. Results for Core i3-2130 were determined based on a variety of tests. Performance numbers for Core 2 Quad Q8400 were derived from test results of other CPUs with identical core and microarchitecture. As a note, the estimate has greater error of margin than results obtained using real-world benchmarks. Additionally, this is an averaged performance, and the shown results may differ from results, that you may see in individual tests.

Q8400 vs i3-2130 specifications comparison

The graphs below compare the most important characteristics of the Q8400 and Intel Core i3-2130 microprocessors. These features, as well as an IPC (instructions per cycle) number, determine how well a processor performs. The "Number of cores / threads" graph shows the number of cores (darker area). Lighter area on the graph corresponds to 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 Intel Core 2 Quad Q8400 and Intel Core i3-2130 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.
