A new Alder Lake benchmark has been posted with a for sale listing, potentially showing Alder Lake running in its new Gear 4 mode. According to @harukaze5719, this latest leak comprised a Core i5-12600K 10-core CPU running the AIDA64 cache & memory test, with a kit of DDR5 memory operating at DDR5-6400. Memory bandwidth was impressive at around 88-90GBps. However, memory latency took a huge hit, running at a sluggish 92.5ns.
According to the listing, the system ran with Gear 4 enabled. In the last decade, Intel hasn’t released a single architecture that approached 92.5ns of memory latency. Only AMD’s original Zen architecture was capable of such laggy behavior, and it was known for its memory bottlenecks in that first-generation iteration.
