Intel · Core i7 · 2013 · LGA1150
The Intel Core i7-4771 is a desktop processor with 4 cores, released in 2013. It is part of the Core i7 lineup, using the 4th Gen platform, and fits the LGA1150 socket. Internally, it is built on the "Haswell" architecture. Thanks to Intel Hyper-Threading, each core can handle two instruction streams simultaneously, yielding a total of 8 threads for improved parallelism. The Core i7-4771 has a base clock of 3.5 GHz and can boost up to 3.9 GHz depending on workload and thermal headroom. Intel manufactures the "Haswell" silicon on a 22nm process node. Its multiplier is locked, so any overclocking has to come from raising the base clock rather than the multiplier. This processor supports DDR3 memory. With a TDP of 84W, the Core i7-4771 sits in a typical power envelope for a modern desktop CPU. Integrated graphics are provided by the HD 4600 solution, so a discrete GPU is not required for display output. The cache hierarchy consists of 32KB/core of L1, 1MB of L2, and 8MB of L3 cache.
Standard locked-multiplier part.
