Twat McTwatterson posted:I get that they make computer chips. But I don't understand why some only make CPUs or GPUs or AMD happens to make both. But Intel just recently or is about to come out with their first GPU? But why hadn't they before? And why doesn't NVIDIA make CPUs? To address this part specifically, several years ago AMD bought ATI, which was a company that exclusively made graphics cards. So now they can do both pretty easily! Intel has been making GPUs since the 90s, they just kinda suck at it. Every time they announce that they're going to make another one a bunch of nerds get super excited and then it comes out and it's trash. Someone should probably tell them to stop. Nvidia doesn't make CPUs because I guess they don't want to? Sometimes companies don't make certain things that other companies make.

While most computing operations only require a logic gate, and science has been yapping on about this “quantum superstate” for years, amd processors have been capable of running 4 electronic states for years. On, not, null, both, and the new quantum state, by. So we should really be able to invoke not only reason but also feeling (understanding) on existing systems.

they are like democrats and republicans, they take turns being the one in charge or the scrappy underdog, and pretend they are in close competition. but actually both sides are the same and are conspiring to keep you oppressed using wedge issues like proprietary vectorized instruction standards to radicalize their respective user bases.

What i want to know is how apparently the entire world depends on TSMC for good chips and intel and china and samsung have had literally no success in catching up. Like what the gently caress, all their billions combined haven’t been able to beat a company whose talent and resource pool is the island of taiwan. it’s nuts

He was a complete weirdo in every way with strange hair and a big stupid hat and he just like stared at me with this judgemental look, like just straight in the eyes for minutes on end and didn't even blink. Not even once. Then he goes like "why you jacking off in the middle of the street?" WTF?! Don't talk to me while i'm jacking it you freak!!

The GPU was superseded by the NKVD, which was itself superseded by the KGB. They all dealt in counterintel, though.

I can make an attempt, I guess? A GPU is a specialized CPU - but to explain how, let's begin by describing a modern "normal" CPU. In a CPU, the actual "processing" hardware handles tasks like "do math on these numbers" and "compare these things" and "set the next instruction to be executed to be the one at this place in RAM". It works with registers, tiny fast pieces of memory that are as fast as the processing hardware but only hold one value each. I'll use "r1" and "r2" and so on as example registers. To keep this fed with instructions and data, another part of the hardware talks to the RAM chips. Those are way slower than a CPU: You can do hundreds of instructions in the time it takes to get something from RAM. To help cover that up, there's some cache on the CPU; memory that's almost as fast as the computing parts, but expensive and power hungry. In an old-school CPU, you grabbed one instruction from memory, did whatever it said (something like add r1 to [ the value that's in RAM at the address in r2 ] and store the result in r3), and when that was complete, you started on the next instruction. That can lead to a lot of idle time, though - sitting around to wait for RAM is a big one. The CPU also has parts that do different things: The largest and most power-consuming ones are typically the math ones - there's separate hardware for integer math (whole numbers) and floating-point math (numbers with decimals, which are way more complicated). If you do one instruction at the time, a lot of CPU will be idle at any time. To speed things up, a more modern CPU (and by modern I mean the 1995 Pentium Pro) can start executing multiple instructions at once. Part of the trick is to split instructions into smaller parts: Say you have compare [the memory at the address stored in r1] to r2. You can split that into read the value at [r1] into a temporary register; compare temporary register with r2. If you do this decoding ahead of time, you can skim through the queue of decoded instructions looking for anything that reads from memory - and start pulling things from memory early. You can also do independent instructions simultaneously: Say you have code:code:It gets way worse, though. The typical code you run on a CPU has loads of branches - places where you do different code depending on the results of a comparison. To keep busy, modern CPUs can get quite deep into "speculative execution", where they run entire blocks of code ahead of time because there's a decent chance they'll need the results ... but they may just end up throwing them away. To make this efficient, they have large caches, and their RAM interface will do all sorts of informed guesswork (like "if you've asked for these four locations in a row, surely you'll want the next 64 as well" to reduce waiting. When you run through the same code more than once, they'll also keep statistics on "how often is this test true", and use that to optimize what parts to speculatively run first. The end result of this is that a modern CPU is an absolute brute force monster at chewing through messy, branching, code, and can have a lot of things happening at once. The downside is that all this takes up a lot of physical space, and eats a lot of power. You also have multiple of these cores: A four-core CPU has four copies of most of the above. The cores typically have some "private" cache, and a larger one shared between them - and they share the memory controller. Sometimes, two adjacent cores may share some execution hardware - I think some older AMD designs shared the floating point math units between pairs of cores, for instance. On the other end of the scale, what makes GPUs different? GPU code is typically very simple: "multiply every value in this list with the corresponding value in this list of the same length"; "do this trigonometry operation to each number in this list", and so on. Lots of math, but next to no branching, and the memory access is usually more predictable. GPU code also tends to have special instructions for memory handling ("grab numbers from all these addresses and put them into a contiguous list"), I think? The end result is that you can get good performance from a CPU that's way simpler than the brute force beats described above - it's basically math units with a little bit of glue. That makes each CPU core comparatively tiny - so you can have hundreds or thousands of them in a chip that's still manageable in size and power consumption. They also prioritize floating point math, since that's much more common in GPU code than in typical CPU code. Modern CPUs all look kind of similar, since they are made to be fast at running the same code - but there's a lot of implementation details that differ. Exactly the same is true of GPUs. AMD and Intel make CPUs, and entirely separately, Intel, AMD and nVidia make GPUs. Computer viking fucked around with this message at 11:42 on May 11, 2022 |

Also Intel makes a ton of poo poo outside of CPUs. So to answer the question in the first post, different companies have different business models. Shocking, I know.
