Zen 4 vs. Zen 4c differences are basically non existent – besides the L3 cache
- rektide 3y agoYet the core - cache aside - is significantly smaller. Supposedly on the same process but maybe maybe the transistors are built different to explain this. But I tend to think this analysis is just ignorant. There's so many millions of things not on that spec sheet. Every stage of the pipeline has all kinds of tweakable parameters. Is the branch prediction the same? Is cache associativity the same? Are there the same number of execution units, with the same capabilities? Something changed to make the core itself smaller. We just can't read some simple specs like this & know what.
- brucethemoose2 3y agoThat is the idea, right? Same exact core, with the underlying transistor layout optimized for density instead of clockspeed and less L3. TBH Renior and Cezzane seem like "Zen 2C" and "Zen 3C" without the marketing. Their caches and clockspeeds were cut the same way, though they didn't have the area reductions Zen 4C has IIRC.
