CPU Comparison
Intel Core i7-5775C vs Intel Core i7-6700T
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.
