All Your Consoles Are Belong To x86.
Ever since the first console was released they have always been at arms length with the greater world of computing. Initially this was just a difference in inputs as consoles were primarily games machines and thus did not require a fully fledged keyboard but over time they grew into being purpose built systems. This is something of a double edged sword as whilst a tightly controlled hardware platform allows developers to code against a set of specifications it also usually meant that every platform was unique which often meant that there was a learning curve for developers every time a new system came out. Sony was particularly guilty of this as the PlayStation 2 and 3 were both notoriously difficult to code for; the latter especially given its unique combination of linear coprocessors and giant non-linear unit.
There was no real indication that this trend was going to stop either as all of the current generation of consoles use some non-standard variant of some comparably esoteric processor. Indeed the only console in recent memory to attempt to use a more standard processor, the original Xbox, was succeeded by a PowerPC driven Xbox360 which would make you think that the current industry standard of x86 processors just weren’t suited to the console environment. Taking into account that the WiiU came out with a PowerPC CPU it seem logical that the next generation would continue this trend but it seems there’s a sea change on the horizon.
Early last year rumours started circulating that the next generation PlayStation, codenamed Orbis, was going to be sporting a x86 based processor but the next generation Xbox, Durango, was most likely going to be continuing with a PowerPC CPU. As it turns out this isn’t the case and Durango will in fact be sporting an x86 (well if you want to be pedantic its x86-64, or x64). This means that its highly likely that code built on the windows platform will be portable to Durango and makes the Xbox the launchpad for the final screen in Microsoft’s Three Screens idea. This essentially means that nearly all major gaming platforms share the same coding base which should make cross platform releases far easier than they have been.
News just in also reveals the specifications of the PlayStation 4 confirming the x86 rumours. It also brings with it some rather interesting news: AMD is looking to be the CPU/GPU manufacturer of choice for the next generation of consoles.
There’s no denying that AMD has had a rough couple years with their most recent quarter posting a net loss of $473 million. It’s not unique to them either as Intel has been dealing with sliding revenue figures as the mobile sector heats up and demand for ARM based processors, which neither of the 2 big chip manufacturer’s provide, skyrockets. Indeed Intel has stated several times that they’re shifting their strategy to try and capture that sector of the market with their most recent announcement being that they won’t be building motherboards any more. AMD seems to have lucked out in securing the CPU for the Orbis (and whilst I can’t find a definitive source it looks like their processor will be in Durango too) and the GPU for both of them which will guarantee them a steady stream of income for quite a while to come. Whether or not this will be enough to reinvigorate the chip giant remains to be seen but there’s no denying that it’s a big win for them.
The end result, I believe, will be an extremely fast maturation of the development frameworks available for the next generation of consoles thanks to their x86 base. What this means is that we’re likely to see titles making the most of the hardware much sooner than we have for other platforms thanks to their ubiquity of their underlying architecture. This will be both a blessing and a curse as whilst the first couple years will see some really impressive titles past that point there might not be a whole lot of room for optimizations. This is ignoring the GPU of course where there always seems to be better ways of doing things but it will be quickly outpaced by its newer brethren. Combine this with the availability of the SteamBox and we could see PCs making a come back as the gaming platform of choice once the consoles start showing their age.
