Intel Core i5-2400 advantages



Intel Core i5-2400
  • Our estimates show that the Intel i5-2400 performs 68% better when running single-threaded tasks.
  • According to our estimates, multi-threaded performance of the Intel i5-2400 is higher.
  • The i5-2400 features SSE4.2 instructions.
  • The Intel i5-2400 processor supports AES extension to the instruction set, used to accelerate AES encryption and decryption. The technology is valuable if you need to protect your disk or network data.
  • This CPU incorporates AVX instructions, that were introduced in modern processors not too far ago. While these extensions are not broadly supported by programs yet, their support should improve in future apps.
  • The processor comes with integrated HD 2000 GPU. While this Graphics Processing Unit is not fast enough to run latest games with all settings on, it can be used for casual gaming and 3D applications.

Q8400 vs i5-2400 estimated performance

The charts below illustrate relative performance of Core 2 Quad Q8400 and Core i5-2400 microprocessors. Results for Core i5-2400 were determined based on a variety of benchmarks. 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 tests. Also, this is an averaged performance, and the difference in individual benchmarks may be lower or higher than what you see in the charts here.

Q8400 vs i5-2400 specifications comparison

The graphs below compare the most important characteristics of the Intel Q8400 and Core i5-2400 microprocessors. These features, as well as an IPC (instructions per cycle) number, determine how well a microprocessor performs. The "Operating frequency" chart uses dark color to represent base frequency, whereas lighter area is for extra frequency, provided by Turbo feature. 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.
