This is the actual truth. Revisiting the catalog of early cross platform games and it's evident that Sony engineers couldn't get anything running well on there for the first three years of its lifespan. The same games ran just fine on the Xbox360.

KISS be like: am i a joke to you?

its why bethesda games always had lots of problems on ps3 and their dlc was always delayed

Nah, that's still a bunch of bull, they designed it and have all the documentation. They know all of its functionality, hidden or otherwise, it's "undocumented" functions, it's quirk's, the very ins and outs of it. They probably still have original designers on staff. They have far more knowledge and experience of their own design than any game developers.

And yet RPCS3, an open source PS3 emulator based on reverse engineered research is able to achieve decent playability on most games.

Not to mention, they're a multi-billion dollar company, don't make excuses for them.

Yes it is hard, and that was their damn fault. I can’t believe they expected developers to have to program which processors take which loads with such granularity. Unbelievably stupid.

I don't think it being hard is really the issue. Sony is a billion dollar multi-national corporation and they don't get any benefit of the doubt whatsoever. Is it hard? Maybe it is, but maybe they should have thought of what they were going to do in the future when they were designing this. As was pointed out elsewhere, volunteers making an open source emulator are managing it so Sony not wanting to, or being unable to, isn't an excuse.

It was very experimental, that’s really the reason Sony went with it and it was at the genesis of multi threaded processing, so the jury was still out on which way things would go.

Your description of it is a little wrong though, it wasn’t multiple CPUs, at least not gore would be traditionally thought. It was a single dual core CPU, with 6 “supporting cores” so not full on CPUs. Kind of like an early stab at octocore processors when dual core was becoming popular and quad core was still being developed.

I remember that the ability to boot Linux was a big deal too and a university racked 8 PS3s together into basically a 64 core super computer. I’m actually sad that didn’t go further, the raw computing power was there, we just didn’t really know what to do with it besides experiment.

Honestly I think someone had a major breakthrough in multi-core single-unit processors shortly after the PS3 launch that killed this. Cell was just a more expensive way to get true multi threaded processing and a couple years later it was cheaper to buy a 32 core processor.

Maybe in a different timeline we’re all running Cell processors in our daily lives.

PS3 most certainly had a separate GPU - was based on the GeForce 7800GTX. Console GPUs tend to be a little faster than their desktop equivalents, as they share the same memory. Rather than the CPU having to send eg. model updates across a bus to update what the GPU is going to draw in the next frame, it can change the values directly in the GPU memory. And of course, the CPU can read the GPU framebuffer and make tweaks to it - that's incredibly slow on desktop PCs, but console games can do things like tone mapping whenever they like, and it's been a big problem for the RPCS3 developers to make that kind of thing run quickly.

The cell cores are a bit more like the 'tensor' cores that you'd get on an AI CPU than a full-blown CPU core. They can't speak to the RAM directly, just exchange data between themselves - the CPU needs to copy data in and out of them in order to get things in and out, and also to schedule any jobs that must run on them, they can't do it themselves. They're also a lot more limited in what they can do than a main CPU core, but they are very very fast at what they can do.

If you are doing the kind of calculations where you've a small amount of data that needs a lot of repetitive maths done on it, they're ideal. Bitcoin mining or crypto breaking for instance - set them up, let them go, check in on them occasionally. The main CPU acts as an orchestrator, keeping all the cell cores filled up with work to do and processing the end results. But if that's not what you're trying to do, then they're borderline useless, and that's a problem for the PS3, because most of its processing power is tied up in those cores.

Some games have a somewhat predictable workload where offloading makes sense. Got some particle effects - some smoke where you need to do some complicated fluid-and-gravity simulations before copying the end result to the GPU? Maybe your main villain has a very dramatic cape that they like to twirl, and you need to run the simulation on that separately from everything else that you're doing? Problem is, working out what you can and can't offload is a massive pain in the ass; it requires a lot of developer time to optimise, when really you'd want the design team implementing that kind of thing; and slightly newer GPUs are a lot more programmable and can do the simpler versions of that kind of calculation both faster and much more in parallel.

The Cell processor turned out to be an evolutionary dead end. The resources needed to work on it (expensive developer time) just didn't really make sense for a gaming machine. The things that it was better at, are things that it just wasn't quite good enough at - modern GPUs are Bitcoin monsters, far exceeding what the cell can do, and if you're really serious about crypto breaking then you probably have your own ASICs. Lots of identical, fast CPU cores are what developers want to work on - it's much easier to reason about.

I knew a Datacenter that had hundreds of ps3s for rendering fluid simulation and other such things that at the time were absolutely cutting edge tech. I believe F1 and some early 3d pixar stuff was rendered on those farms. But like all things, technology marched on. fpgpas and cuda have taken that space.

Cell definitely was heavily used by specialist/nichr industry though.

I wonder if I can find you some link to explain it better than the rumours I heard from staff that used to work in those datacentres.

Hmm hard to find commercial applications, probably individuals might have blogged otherwise here's what I'm talking about: https://en.m.wikipedia.org/wiki/PlayStation_3_cluster

I think the application of it was wrong.

You basically had game devs that wanted to build cross platform easily. PC, Xbox, and Nintendo used standard architecture while ps3 was unique.

That basically meant you had to develop for ps3 as an entirely separate game than the other major systems.

The xbox one/series consoles run a good number of 360 games dispite the fact that the 360 uses powerPC and the newer consoles are x86.

Sony is out here getting shown up by rpcs3 having about 70℅ of their listed games working perfectly fine by hobbyists reverse engineering the ps3.

There's some weird online connection issues on 360 that occur with certain modern routers. You get dropped randomly from the game. Annoyingly, the emulated 360 on One doesn't skirt around the issue. It was annoying for Borderlands but made Left 4 Dead worthless on anything besides easy

Apple did the same again with their ARM migration and in my experience it worked great. I believe Microsoft also has a solution for running x86 software on ARM.

There are design decisions that I really don't understand why Sony made them. They do, however, make the PS3 the ideal piece of hardware if you're wanting to build an adhoc super computer

I would argue its what you get when you build hardware without any consideration for the people writing the software. Which is just as much as an epitome if a kind of silly.
