i7-3770K vs i7-4770K performance comparison

The charts demonstrate performance of Core i7-3770K and Core i7-4770K processors in various types of tasks. The numbers for 'Single-threaded performance', 'Multi-threaded performance' and 'Discrete Graphics performance' charts are calculated as an average of several related benchmarks, that you can find in the "Benchmarks" tab. As a result, performance in individual benchmarks may be worse or better than what you see in the charts on this page. The 'Overall performance' chart calculates an average of all-around performance benchmarks, and benchmarks, specific to each application type. The 'Price-performance ratio' shows how much more performance you will get per dollar spent. This ratio does not include the cost of other system components.

Benchmarks

System setup

Below is a partial set of Intel Core i7-3770K and i7-4770K benchmarks from our CPU benchmark database. The former processor was tested on ASUS P8P67 motherboard with 2 GB dual-channel Corsair TR3X3G1600C9 DDR3 memory, and MSI R6670 1GB GDDR5 (ATI Radeon). The latter processor was tested on Intel DH87RL motherboard, that had 2 GB dual-channel Corsair TR3X3G1600C9 DDR3 memory, and MSI R6670 1GB GDDR5 (ATI Radeon) graphics. For different system configurations please see tests of Core i7-3770K and i7-4770K CPUs in our benchmark database.

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 i7-4770K 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 i7-4770K 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.
