Dear Community,
ever since the invention of the 5770c with edram L4 cache, I have been curious about the topic. The 5770c was very fast in some gaming applications, presumably those with lots of cache misses. There has been talk about edram in various CPUs since then, the ones I remember were Skylake and Zen 3. Since the latest leak, edram on Zen 3 seems pretty unlikely.
This leads to my question: Why is no one making a desktop CPU with edram L4? Is it too expensive to produce? Is the latency not good enough? Is the market for such a product too small?
There must be some reason for this. My best guess is, that AMD is focused on the server marked and Zen is mostly a by product. High end gaming CPUs are probably such a small market, developing this may not be feasible. But maybe you got a better technical explaination for this.
Thanks in advance for input on that matter!
