No. The reason the average consumer accepts limited cache memory in CPU / GPU / HDD / SSD etc, despite the high bandwidth they offer is simply because of the cost - they are very expensive. Thus, consumers accept the reasonable compromise to sacrifice some performance to match their budget. Otherwise, why wouldn't we all purchase server grade hardware? Or we could all be using high-speed SRAM for our RAM without even the need for cache memory in our CPUs. Hell, if SSDs get as fast as even dynamic RAM then we could even do away with the RAM completely - it would be a significant departure / upgrade from the Princeton and Harvard computer architecture that we currently use. Yes, we expect cache to be built-in because the manufacturers of high-speed memory realistically don't expect the average consumers to be their target market, and thus chose the B2B model to sell their product. Nobody (that I know of) has also explored offering upgradeable cache memory as an option to consumers (hard to know if it even possible with current CPU / SoC hardware). As for consumers changing their expectation to accepting soldered RAM and SSDs, that remains to be seen - anything is possible with powerful lobbying and PR. Personally, I think Intel and AMD would be fools to not treat any "integrated" RAM in their future CPUs as "L4 / L5 cache memory" while still fully supporting DIMM DDR RAM as that would make their CPUs more powerful and more desirable than Apple Silicon SoCs. Note that unlike Apple, they don't sell a closed-box solution and have to support multiple OS platform. Thus, it would be more difficult for them to offer a "one size fits all" built-in RAM with their CPUs. |
