A Broadwell Retrospective Review in 2020: Is eDRAM Still Worth It?

See the original posting on Anandtech

Intel’s first foray into 14nm was with its Broadwell product portfolio. It launched into the mobile market with a variety of products, however the desktop offering in 2015 was extremely limited – only two socketed desktop processors ever made it to retail, and in limited quantities. This is despite users waiting for a strong 14nm update to Haswell, but also because of the way Intel built the chip. Alongside the processor was 128 MB of eDRAM, a sort of additional cache between the CPU and the main memory. It caused quite a stir, and we’re retesting the hardware in 2020 to see if the concept of eDRAM is still worth the effort.
