Intel Core i7-6700 vs Intel Core i5-5675C
A side-by-side comparison of specs, performance and value. The Intel Core i7-6700 is a mainstream quad-core desktop processor that served as the backbone of the 6th Generation Skylake lineup. Released in 2015, it brought incremental but meaningful improvements over the previous Haswell generation, including higher IPC, improved integrated graphics, and the introduction of DDR4 memory support to the mainstream market. Operating at a base clock of 3.4 GHz and boosting up to 4.0 GHz, it delivered strong single-threaded performance ideal for gaming and everyday productivity. With four cores and eight threads, it handled the multitasking demands of the era effectively. The 65-watt TDP ensured it ran efficiently and coolly, making it a staple in millions of office and home PCs worldwide. The inclusion of Intel HD Graphics 530 allowed for smooth 4K video playback and basic media tasks without requiring a discrete GPU, cementing its reputation as a versatile, do-it-all processor for mainstream users.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Handles office workloads and multitasking without issues.
Quad-core performance at 3.6GHz is snappy for everyday tasks and light creation.
Gaming
Good for 60fps gaming with a discrete GPU, but struggles with modern high-refresh titles.
Iris Pro 6200 allows for solid 1080p gaming on older titles without a dedicated GPU.
Virtualization
Capable of running 1-2 light VMs.
Handles basic VMs well, though limited by 4 threads.
Efficiency
Highly efficient 65W design.
Broadwell's 14nm process is quite efficient, especially when TDP is configured down.
