Editing intel/crystal well

'''Crystal Well''' is the codename for the L4 cache, a discrete [[eDRAM]] silicon die, which is featured in the [[Iris Pro]]-equipped [[Haswell]] microprocessors. The eDRAM silicon die is separate from the main [[Haswell]] die but is package together with it. Crystal Well based processors started shipping in the third quarter of 2013.

Crystal Well is a true 128MB [[L4 Cache|L4$]] which could be utilized by the core itself, not just by the [[Iris Pro]]'s Framebuffer. I.E. L3$ values that gets evicted go into the L4$. The L4$ caches bother GPU and CPU memory accesses; memory is partitioned between. If the GPU is disabled, such as when a discrete GPU is installed, the L4$ will be used exclusively by the CPU.

[[Intel]] has not disclose much technical specs regarding how the crystal well die communicates with the main die. Intel has stated that the cache is capable of delivering 100GB/s bandwidth (50GB/s in each direction).

-Note that since {{intel|Skylake|l=arch}}, Intel has changed how the [[eDRAM]] works to act as a side cache instead of an L4 cache (see {{intel|Skylake#eDRAM_architectural_changes|l=arch}} for details).
