Benchmarks

System setup

Intel Core i7-3770K and Pentium E2140 processors were tested using different system components, that are identified by MB, RAM and VID columns in the tables below. The numbers in each of these columns correspond to one of motherboards (MB), memory configurations (RAM) or graphics adapters (VID), listed below:

MB - Motherboard(s):
1. ASUS P8P67
2. ASUS P8H61-M
3. ASROCK 4CORE1600TWINS-P35
4. INTEL DP965LT

RAM - Memory:
1. 2 GB DUAL-CHANNEL CORSAIR TR3X3G1600C9 DDR3
2. 2 GB DUAL-CHANNEL CORSAIR CM3X1024-1333C9 DDR3
3. 2GB DUAL-CHANNEL CORSAIR CM2X1024-6400C4

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 i7-3770K vs Pentium E2140 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 i7-3770K vs Pentium E2140 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 i7-3770K vs Pentium E2140 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.
