Benchmarks
System setup
Below is a complete set of Intel Core 2 Duo E7400 and Pentium G3240 benchmarks from our CPU benchmark database.
The former processor was tested on ASRock 4Core1600Twins-P35 motherboard with 2 GB dual-channel Corsair CM3X1024-1333C9 DDR3 memory, and Powercolor 24PRO256M DDR2 (ATI Radeon HD2400).
The latter processor was tested on ASRock Fatal1ty Z97 Killer motherboard, that had 2 GB dual-channel Corsair TR3X3G1600C9 DDR3 memory, and MSI R6670 1GB GDDR5 (ATI Radeon) graphics.
All tests were performed at default frequency and voltage, using manufacturer's stock fan/heatsink. None of the components were overclocked. Motherboard BIOS options were left at default settings.
The results of all benchmarks are broken into four categories: multi-threaded, single-threaded, memory intensive and graphics / gaming.
Core 2 Duo E7400 vs Pentium G3240 single-threaded benchmarks
Single-threaded benchmarks run on a single CPU core, and do not depend
on such features as the number of cores, or Hyper-Threading
technology. Additionally, they do not utilize on-chip caches,
dedicated to other cores.

Core 2 Duo E7400 vs Pentium G3240 multi-threaded benchmarks
Multi-threaded benchmarks utilize all CPU cores and other on-chip
resources (on-chip caches, internal buffers, etc). Intel's
Hyper-Threading feature also helps to improve multi-threading
performance.

Core 2 Duo E7400 vs Pentium G3240 graphics benchmarks
Graphics benchmarks depend on the type of integrated or discrete
graphics adapter, and to less extent on the processor performance.
Because these benchmarks are synthetic, they may not truly represent
gaming performance. However, they still can be used to estimate whether
one processor will perform faster or slower than another CPU
in games and other 3D tasks.
Important! The processors were tested using different types of graphics adapters, that may not be suitable for comparison.

Core 2 Duo E7400 vs Pentium G3240 memory performance
Memory-intensive tests or programs move large amounts of data to/from
memory, and they depend more on memory throughput and the size of
on-chip caches, rather than on CPU integer/FP/SIMD performance.

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 Duo E7400
and Intel Pentium G3240 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.
