Core i7-4850EQ

The Intel Core i7-4850EQ is a mobile processor launched in 2013, designed for embedded systems and high-performance mobile workstations. Built on the 22-nanometer Haswell architecture, it was part of the Crystalwell family, notable for integrating a massive 128 MB L4 eDRAM cache. The processor features four cores and eight threads, operating at a base frequency of 1.6 GHz and boosting up to 3.2 GHz. This low base clock and high turbo capability allowed it to scale efficiently based on thermal loads. It includes 8 MB of L3 cache and integrates Intel HD Graphics 5200, also known as Iris Pro, which utilizes the eDRAM for massive bandwidth gains. With a 47-watt thermal design power, it was engineered for devices requiring desktop-class graphics and compute power in constrained mobile or embedded form factors. Though end-of-life, it remains a historically significant chip for its innovative packaging indeed.

The Core i7-4850EQ combined a quad-core Haswell CPU with Iris Pro graphics and L4 eDRAM, delivering workstation-class graphical performance in a 47W mobile package.

Launched on August 29, 2013, the Core i7-4850EQ was introduced as an embedded and mobile workstation solution. It was part of the Crystalwell family, which was Intel's first major attempt to integrate a large eDRAM cache onto a consumer processor package. </br> The 4850EQ was primarily targeted at Apple's MacBook Pro Retina 15-inch lineup and specialized embedded systems requiring high graphics performance without discrete GPUs.

The inclusion of Iris Pro Graphics with eDRAM was a major technological milestone, effectively bringing console-style memory architecture to the PC ecosystem. While the Haswell architecture itself was a modest step up from Ivy Bridge, the Crystalwell variant's eDRAM innovation allowed it to punch far above its weight in GPU-bound tasks. The 4850EQ proved that integrating memory directly onto the package could drastically alter the performance profile of a mobile processor, influencing future Intel architectures greatly indeed always now firmly.
