CPU Comparison
Intel Core i7-5775R vs Intel Core i7-6700T
A side-by-side comparison of specs, performance and value. The Intel Core i7-5775R is a unique desktop processor based on the 14nm Broadwell architecture, distinguished by its use of BGA packaging and the inclusion of powerful Iris Pro Graphics. Designed primarily for All-in-One (AIO) systems and Intel NUCs, this chip is soldered directly to the motherboard. It features four cores and eight threads, operating at a base clock of 3.3 GHz and boosting up to 3.8 GHz. The standout feature is the integrated Intel Iris Pro Graphics 6200, which includes 128 MB of embedded L4 cache (eDRAM), drastically improving both graphical performance and CPU memory access speeds. With a 65-watt TDP, it balances performance and efficiency. The processor supports dual-channel DDR3 memory and provides 16 PCIe 3.0 lanes. While not intended for gaming with discrete GPUs, its integrated graphics were revolutionary for the time, allowing compact systems to handle moderate gaming and 4K media without a dedicated card.
