Benchmarks

System setup

Below is a complete set of Intel Core i7-4770 and i7-920 benchmarks from our CPU benchmark database. The former processor was tested on Intel DH87RL motherboard with 2 GB dual-channel Corsair TR3X3G1600C9 DDR3 memory, and MSI R6670 1GB GDDR5 (ATI Radeon). The latter processor was tested on MSI X58M motherboard, that had 3 GB triple-channel Corsair TR3X3G1600C9 DDR3 memory, and Powercolor 24PRO256M DDR2 (ATI Radeon HD2400) 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 i7-4770 vs i7-920 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 i7-4770 vs i7-920 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 i7-4770 vs i7-920 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.
