NES = 8 Bit
SNES = 16 Bit
PSX = 32 bit
PS2 = 64 bit
PS3 = 64 bit
PS4 = 64 bit
What gives? Why have processing speeds stayed the same when they used to increase exponentially from generation to generation?
>>51579512
I know this is a meme thread, but the 'bit'-ness of a console was determined by the largest bus it had.
PS4 has a 256 bit bus on its graphics card, which would make it a 256 bit console. The PS3 had a 128 bit bus on its graphics card. You're list should be:
NES = 8 Bit
SNES = 16 Bit
PSX = 32 bit
PS2 = 64 bit
PS3 = 128 bit
PS4 = 256 bit

Doesnt it mean the processor is running at 64 mph?
>>51579584
If your processor is running at 64mph you better catch it.
>>51579512
>processing speeds
no it's about the amount of memory they can handle. 8 -> 16 -> 32 -> 64 was required, but 64 bit can use like 2 extobytes or some other retarded amount of memory we will never reach, no need to increase.
>>51579512
>I don't understand exponential growth
Also bits refers more to how much memory can be used
The problem may be solved using simple addition. With 64 squares on a chessboard, if the number of grains doubles on successive squares, then the sum of grains on all 64 squares is: 1 + 2 + 4 + 8... and so forth for the 64 squares. The total number of grains equals 18,446,744,073,709,551,615, much higher than what most intuitively expect.

>bigger than 64bit
because if the number is larger than 64 bits allows, you can represent it close enough with floatingpoint
also doubling register size is stupidly expensive

keked.
thanks anon
didn't /v/ give you enough (you)'s?

>finite series of geometric sequence
>simple addition
The sum can be more explicitly written as an exponentiation. It's not really described by addition
>>51579861
The exercise of working through this problem may be used to explain and demonstrate exponents and the quick growth of exponential and geometric sequences. It can also be used to illustrate sigma notation. When expressed as exponents, the geometric series is: 20 + 21 + 22 + 23... and so forth up to 263. The base of each exponentiation, "2", expresses the doubling at each square, while the exponents represent the position of each square (0 for the first square, 1 for the second, etc.).

you're missing nintendo 64

>the 'bit'-ness of a console was determined by the largest bus it had
No, it was not. The "bit-ness" is the memory address size of the architecture of each console, just like Pentium 4 processors were 32-bit and everything since the Athlon 64 and Core 2 have been 64-bit. Also, the same way most smartphones had 32-bit SoCs until recently.
Also, the PS2 was not 64-bit, its CPU had a mix of 32-bit and 64-bit processing units. The PS3 and PS4 are both 64-bit, like every other CPU we have today.
I don't know where you idiots get this retarded idea that it's about buses. And if it where, the PS3 would be 256-bit, because that's the width of the interconnect bus between Cell's core and vector units.
>>51579986
The Atari Jaguar was heavily marketed as the first 64-bit console because it had a 64-bit graphics co-processor AKA a GPU.
It's all just marketing buzzwords with console 'bitness,' the bitness of the ISA is a whole different matter.
>>51579959
Well that's obviously 64 bit
>>51579512
Holy shit, how retarded can someone be
max memory on 32-bit architecture is 2^32 which levels out to just under 4Gb of RAM
max memory on 64-bit architecture is 2^64 which is around 16 billion gigabytes
i don't think we'll be seeing 128-bit any time soon.
>>51579986
There were plenty of pentium 4 chips capable of 64bit archs
>>51579512
The nintendo64 was 64bit too desu
>yfw nintendo literally skipped over the 32bit generation
>>51579560
>by the largest bus it had.
No that was what fucking retards did. The PS2 had a 1024bit bus on the GPU and people thought it meant the PS2 was 1024bit.
>>51580125
and modern x86 cpus only use 48 bits of it desu
i am prettu sure its just how many parts make the cpu
>>51580170
That's what I'm saying.
Talking about 'bitness' is about as worthwhile as talking about how a hummer is faster and better than ferrari because it has more screws in it.
>>51580148
>wat is gpu architecture
68k is 32-bit on 16-bit system bus with 24-bit addressing. Skylake is 512-bit AVX on a 64-bit system bus with 48-bit addressing. Can you extract from this the defining metric that everyone uses in the PC industry? Hint: it's not graphics cards, SIMD, or internal bit rate.
