Hmm still not natively backwards compatible allowing for all the quiet re-releases a couple of months after launch, a 32 bit AMD processor and an undefined AMD gfx chip. They're not convincing me that's any thing like a supercharged PC.
But if it reduces the current impact on developing games for PCs then that's got to be a good thing and if they want to try to emulate us by referring to themselves as a supercharged PC then again that can only be a positive, after all envy is a terrible thing
they may well do the same sort of thing, Intel and Nvidia maybe we will see a resurgence in pc gaming I bloody hope so
Just because it says it is X86 does not mean it is 32 bit. X86 refers to the Architecture it become synonymous with 32 bit that was the limit at the time . It still most likely is capable of 64 bit instruction sets maybe even 128 bit which Intels chips are capable of now iirc
Depends on how many cores and what the instruction cache sizes will be, and the operating frequencies
I don't think there is much power to be gained from going 64 bit as opposed to 32 bit - from what I remember of CPU architecture the number of bits basically increases the number of possible instructions available and increases the native addressing range - they may do cleverer stuff these days by combining instructions (operators) with data (operands) all in one go, and I can see that improving performance - but dunno - I haven't looked at CPU architecture since the old Intel 80286.
According to this ( dunno if true or not ) but the PS4 has 8 gig of ram meaning it can not be a 32 bit CPUhttp://www.vg247.com/2013/02/20/ps4-has-8gb-of-ram-almost-2-teraflops-of-computational-performance/
X86 dates back to 1978 and chips before the 286 its all about the class of instruction set nothing else IA32 is the 32 bit generation of the X86 cpuIA64 /Intel 64 is Intels 64 bit instruction set for X86 cpuAMD64 is AMDs 64 bit instruction set for the X86 cpuThis information is correct btw
Its a lot of years since I read up on this stuff too but don't forget its not a linear increase though mate, the next jump for instance isn't likely to be 128 bit but 256bit.
Blimey, geeks rule All I'd want to know is - will the console be a worthy successor to the PS3?
I've often wondered about this when it comes to RAM - if it's a 32 bit processor, it can read 4 bytes at a time (in theory) so for maximum granularity it (a 32 bit processor) could theoretocally get at a bit less than 16GB of RAM - if the RAM was organised into 4 byte sectors - just like hard drives have 4K and 16K sectors so that much more than the native addressing range can be stored.

Hell we were discussing how to build network stacks to grab the token
