The real Neanderthal social media account is the one writing that review.

Instruction and data caches have a real, tangible benefit. Although there is a point of diminishing returns, more L3 cache is absolutely worth a 10% clock speed trade-off for consumer systems. Fetching memory from the bus is an order of magnitude slower than fetching from cache, and the processor has to perform other work or stall while it's waiting for that.

But, knowing the bias of the reviewer, they're probably running DDR4 at 5200 MT/s (2000 over JEDEC specs) on their Intel systems to make up for the lack of cache while thinking, "just buy a more expensive processor and RAM, you brain-dead cretins."
