How come computers went from 16 bit from 32 bit with windows 95 and then from 32 bit to 64 bit with windows xp but we still don't have 128 bit computers?
How come computers went from 16 bit from 32 bit with windows 95 and then from 32 bit to 64 bit with windows xp but we still don't have 128 bit co...
most likely because of the israelites
i mean we already have 128-bit computing, just look at NASA
bit is an exponential factor, go look up how much memory 64bit lets you have
becase you have no idea how computers work and have just made yourself look like an idiot.
there's no need for it. The average fag programmer barely takes advantage of 64-bits. The only thing 128-bit is useful for it date-time-based datatypes..
It depends on which bits you're talking about.
Even the most advanced "64-bit" CPUs aren't really 64-bit in terms of physical memory addressability for example - and that was the defining feature of 8-bit, 16-bit, 32-bit CPUs. 14900K only has 46-bit physical address lines.
On the other hand you have the bits in CPU registers. Those are 64-bit for basic x86-64 registers, but there's also 128-bit AVX, 256-bit AVX2, 512-bit AVX-512 and even 2-dimensional tile registers of Intel AMX with 8x16byte capacity (so... 131072-bit).

Because 90% of applications are still 32bit
Not true. It's not 2007 anymore.
2007 wasnt that long ago bud
please list the software you use that's only 32-bit with no 64-bit version available
and no, erotic novels don't count
there are 128bit registers in your cpu right now, used for simd. but it's not needed in general purpose registers because there's no need to address memory higher that ((2^64) - 1). that's > 16 exabytes. no pc currently is capable of having that much ram. afaik the largest amoun ever was 1.5 petabytes.
My pc is capable of having that much ram
128 bit processors do exist
It's bloat though
Does anyone use the full 64 bit address range? I guess 128 bits are useful if yo wish to count every atom in the universe.
64 to 128 isn't 'double', it's like the difference of a million and a trillion
Actually 64bit float is called double.
64bit: 1.84*10^19 addressable memory slots
128bit: 3.4*10^38 addressable memory slots
why do you need more than 64bit?
try killing yourself? this will solve the problem.
Aren't Nvidia GPUs 128 bit?
not in the sense that the gpu can point to 2^128 addresses. for them, each VRAM chip uses 32 bits each so the max number of VRAM chips supported is just the bus width / 32.

Only one of those things can be changed.
128 bits of secret glowie op codes that'll never be fuzzed out
Because there's no use case for using values that are > 64^2-1
We literally have 256 and 512 bit computer right now, available to consumers, for non astromic prices
What did you think 256 and 512 after avx meant? How many cock you could suck?
>Inb4 he meant general registers
(you) dont need it, youre barely using 64 bit to its full potential, the pinacle of computing barely makes use of 64 bits
vector registers are not 512-bit really, they are just multiple packed separate 64-/32-/16-bit values
as in you're not doing operations on one single 512-bit value
Honestly the "bitness" of a computer is mostly a marketing term. The reality is that a modern computer has many different bus, data, address, etc inside of it, and it largely doesn't matter to the consumer.
What's mostly being discussed is the bit width of a virtual memory address. There's no reason to go above a 64-bit address size, and there will not be for quite a long time. To put in in perspective, modern servers support like 1024 GB of memory. The largest supercomputer has 693,000 GB of RAM, barely a ten thousandth of the address space limit, but you can't even make a comparison here because it has thousands of CPU cores too.
So yeah, it's going to take us a very long time to hit the address space limit for a single CPU, if that's ever even practical at all.
