Good, those are things that every Computer Science/Engineer learn in the first semester of the course. And you only really understand by the graduation, and may be never work with it.

Any way, GDDR 5 has nothing special, it just faster than normal DDR 3, but it´s interesting a game studio working that close to the metal for optmisation, that is the benefit of working in only one platform.

For me the guys at Epic and Cryteck are the real gods.

No, this is exactly what we were taught in the first semester *of the course*.

ISA, computer architecture, data paths, single cycle vs. multi-cycle data paths, branch prediction, score boards, caching (strategies, layout, misses), victim caches, data hazards, pipeline stalls, memory layout, cache snooping... All what is on these slides. All the did is fill it up with actual values.

When I read "PS4 has “really really good” branch prediction hardware" then it's not because of the wonder machine PS4 but that AMD has implemented good branch prediction in their CPUs so this applies to all processors of this kind.

We barely even covered any of that in mine.
