CPU Comparison

Core i7-5750HQ vs Core i7-940XM

A side-by-side comparison of specs, performance and value. The Intel Core i7-5750HQ is a mobile processor launched in 2015, targeting high-end laptops and small form factor systems that require robust graphics capabilities without relying on discrete GPUs. Built on the 14nm Broadwell-H architecture, it offers four cores and eight threads, delivering solid multi-tasking performance for its era. The processor runs at a base clock of 2.5 GHz and can boost up to 3.4 GHz. Its most defining feature is the inclusion of Intel Iris Pro Graphics 6200, supported by 128 MB of embedded DRAM (eDRAM). This configuration provides exceptional memory bandwidth, allowing the integrated GPU to handle moderate gaming and hardware-accelerated media encoding far better than standard integrated solutions. With a 47-watt thermal design power, it necessitates adequate cooling. Though end-of-life, the i7-5750HQ was a pioneering chip that demonstrated the potential of integrating large memory caches directly onto the processor package for mobile platforms very impressively indeed.
