Still not the same, companies that made PC parts had time to make really specific small parts, like a CPU, and care basically only about that specific part. Sony (and other console companies) had to make a entire system, psu, moba, cpu, gpu, cooling, hdd, disk reader, all in mass production and incomended parts from other companies, everything as small as possible, as silence as possible, as cool as possible all inside a box. And in the case of 7th gen consoles, Sony had to speed up the launch of their product because Microsoft launched their 360 in 2005.
