Neat, I'm actually mostly happy with the choices they made for a console here, which I haven't been able to say for a few generations now
Slightly faster than I expected as well.
x86 is a good choice, and jaguar is a very good choice for a console. The tool chain is well-developed and optimization should be easier and more portable (using ISPC on the new consoles sounds like fun!). Integrated CPU/GPU and unified memory is a no-brainer as well... everything is clearly going that direction.
8GB is a good size, but all GDDR5 seems like overkill. DDR3 plus a good cache hierarchy could achieve the same result for significantly cheaper. Still, it's obviously "fine", it'll just drive up costs unnecessarily IMO. DDR3 without a good cache would have been a mistake in any case. GDDR latency might make CPU coding slightly more interesting too, but with 8 cores running at fairly low frequencies, it might not be a huge deal anyways. That said, games are going to have to do a better job of parallelism than they have to date, but that's okay too.
Still not clear what they're doing with the hard drive unless I've missed that. best option would probably be small SSD cache (~20GB-40GB maybe?) plus large conventional HDD (~1TB+, 5400rpm is fine). Again, extending the cache hierarchy on down without skipping obvious levels.
I guess it's pretty clear at this point that it's going to be a good chunk more powerful than the next Xbox, but deltas of even up to 2x (which this won't be) aren't always obvious to end users. My biggest fear here is that this is going to be too expensive for most people given what we saw with price sensitivity last generation. I don't feel like Sony can afford to sell it below cost this time around, and 8GB of GDDR5 worries me...
Seems like indeed the hardware is going to have largely converged across PCs and consoles next generation and it's mostly just going to be software games and closed platforms that prevent compatibility. With all of Sony's talk of being an open platform, do you think they'd let me put Linux on the thing and run a steam box if I wanted to? Doubtful
