CPU Comparison
Intel Core i7-5775C vs Intel Core i5-5675C
A side-by-side comparison of specs, performance and value. The Intel Core i7-5775C is a rare and highly sought-after socketed desktop processor based on the 14nm Broadwell architecture. Unlike its BGA counterpart, the 5775R, this chip utilizes the LGA 1150 socket, offering a unique upgrade path for users on older Z97 motherboards. It features four cores and eight threads, operating at a base clock of 3.3 GHz with a turbo boost of 3.7 GHz. The defining feature is the inclusion of Intel Iris Pro Graphics 6200 with 128 MB of embedded L4 cache (eDRAM). This eDRAM not only supercharges the integrated graphics but also acts as a low-latency memory buffer for the CPU cores, giving it an edge in certain CPU-bound gaming scenarios when paired with a discrete GPU. With a 65-watt TDP and an unlocked multiplier, it is a versatile chip. It represents a unique moment in Intel's history where high-end integrated graphics and eDRAM were brought to the standard DIY desktop market.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
4 cores handle office tasks effortlessly, but lack modern IPC.
Quad-core performance at 3.6GHz is snappy for everyday tasks and light creation.
Gaming
The eDRAM provides incredibly smooth frame times in older games.
Iris Pro 6200 allows for solid 1080p gaming on older titles without a dedicated GPU.
Virtualization
Capable of light VMs, but limited by 65W TDP.
Handles basic VMs well, though limited by 4 threads.
Efficiency
14nm process makes it incredibly power-efficient.
Broadwell's 14nm process is quite efficient, especially when TDP is configured down.
