People forget about the things that history teaches us sometimes.
When IBM released their first desktop system containing onboard cache, they found that it could outperform some of their higher end server solutions in certain tasks (the ones containing nothing but high speed RAM for the time). Even if this eDRAM is used purely for caching methods, it will still outperform a ton of higher speed RAM for particular tasks.
Those benefits can be broadened if the developer has control over the eDRAM, though at the cost of a little more complexity. Still this should pose no different to the use of "zero page" memory for more efficient use of the CPU back in the earlier eras.
