Released specs can be deceiving, and memory speed is very important.
The memory speeds aren't outright worse. One uses DDR3 and one uses GDDR5. GDDR5 has worse latency, but higher bandwidth. Sony is making a big bet on using their GPU for computing imo (edit: at least it seems this way if they are focussing so much on bandwidth over latency). It's not a super risky bet, but if we start leaning back towards more CPU intensive tasks it could be hurt by the latency vs the One. GDDR5 is based off of DDR3. GDDR5 is not an upgrade from DDR3, it is an upgrade from GDDR4, which is also based off DDR3 iirc. Their version numbers do not correlate to the same type of thing.
As for 'quite a step up from what we have', sure, a step up from current consoles. Not really a step up from a mid-range PC.
That's deceptive. PCs have a lot of overhead that consoles, in theory, shouldn't. They have worse specs, but they have more access to the full specs of the hardware than a PC game would. PC games also have to cover a huge swath of hardware, and usually are worse for it. Don't underestimate being able to optimize for standardized hardware.
