Sony changed their CPU architecture every time until PS4/5. The only reason some PS3s could play PS2 games is because they had also had PS2 hardware in them. Xbox has been x86 the whole time.

The 360 is IBM power pc based.
The simple answer is that microsoft is a far more advanced company in terms of programming an OS, the gap shows when you compare console securities, where virtually every nintendo or sony device had software vulnerabilities, while microsoft consoles tended to need to be hardmodded
As someone who programmed drivers for nt, it's not, the reason it's easier is because they started later.
Xbox is a mature x86 windows platform, vs ps1 which is an embedded mips system.
They started with their windows directx stack and just kept with it, while ps did a random walk all over the place.
Msft also had really boring hardware, like, they started with a crappy pc, then made a crappy ppc pc, then went back to a crappy pc. The software was simplistic, while Sony made really interesting hardware designs, that turned out to be hard to program, till the ps4 when they just gave up.
Msft traditionally isn't very good at operating systems, they've just had infinite resources and infinite monkeys for 40+ years, and they've been stubborn enough to make it work somehow.
It doesnt say anything about modern consoles though. Although its dofferent at the start, their modern consoles are still effectively full of exploits. Hell VERY recently, "backup" PS4 titles are running on the PS5. Security is the main reason why BOTH the PS5 and the Nintendo Switch do not have easily accessible web browsers while Microsoft can.
I would argue they had to give it up to get the indie scene onboard as I heard many nightmare stories for indies from PS3 era. Was it worth it? I'm sure contributed a great deal to the success of PS4 but it made the PS into just a more affordable gaming PC.
Totally worth it, they spent unimaginable resources trying to make those architectures programmable, now that's all almost free, they just compete for published titles and maybe some secondary features.
MSFT was in a better position because they didn't need to spend those resources, and more importantly the devs didn't either, they could write windows games then port them over easily. Now it's just as easy to do that for ps4/5. All that matters is nailing exclusives and looking cool, plus some marketing which msft sucks at.
It's too early to decide if it was. Yes it was the safest bet, Even though PS4 had a great deal of success you also need to keep in mind, a lot of it was because of politics. Nintendo and MS made huge mistakes at that time and Sony basically ate their lunch.
The older generations were always innovative and pushed the envelop as far as possible, but now PS just a gaming PC that is not upgradable like an actual PC. if you don't recall, the most hyped thing about PS5 was the controller, which is not what you expect the main point of buying a new consol to be.
On the topic of exclusives, I personally hate them. I think it makes a false sense of value in modern consoles where in the past they were intentionally made to take advantage of the architecture to showcase the unique quirks (and ofc the power) of this machine in a tiny box. Now they are usually just political leverages even though the games can be ported to other platforms.
So to reiterate, I agree it definitely had positive net for Sony in the short run, we'll have to wait and see if it will payout in the long run.
Exclusives are terrible for the customer, but they're a way for corporate to control the market, which is a good for them.
We'll see, but I was on the dev side of that nightmare, Sony would have gotten crushed the next gen, they barely made it out of ps3 with their extended developers in tact, nobody liked programming the cell, everybody loves the current system.
But it does reduce competitive surface area, so we'll see. Nintendo is winning now because they didn't follow the same path but they did innovate, more than almost anyone before.
My question is: What innovation do you see that could have been worth a unique architecture to Sony's developers?

The Xbox 360 was based on the same weird, in-order PowerPC 970 derived CPU as the PS3, it just had three of them stuck together instead of one of them tied to seven weird Cell units. The TL;DR of how Xbox backwards compatibility has been achieved is that Microsoft's whole approach with the Xbox has always been to create a PC-like environment which makes porting games to or from the Xbox simpler.
The real star of the show here is the Windows NT kernel and DirectX. Microsoft's core APIs have been designed to be portable and platform-agnostic since the beginning of the NT days (of course, that isn't necessarily true of the rest of the Windows operating system we use on our PCs). Developers could still program their games mostly as though they were targeting a Windows PC using DirectX since all the same high-level APIs worked in basically the same way, just with less memory and some platform-specific optimisations to keep in mind (stuff like the 10MB of eDRAM, or that you could always assume three 3.2GHz in-order CPU cores with 2-way SMT).
Xbox 360 games on the Xbox One seem to be run through something akin to Dolphin's "Übershaders" - in this case, per-game optimised modifications of an entire Xenon GPU stack implemented in software running alongside the entire Xbox 360 operating environment in a hypervisor. This is aided by the integration of hardware-level support for certain texture and audio formats common in Xbox 360 games into the Xbox One's CPU design, similarly to how Apple's M-series SoCs integrate support for x86-style memory ordering to greatly accelerate Rosetta 2.
Microsoft's APIs for developers to target tend to be fairly platform-agnostic - see Windows CE, which could run on anything from ARM handhelds to the Hitachi SH-4 powered Sega Dreamcast. This enables developers who are mostly experienced in coding for x86 PCs running Windows to relatively easily start writing programs (or games) for other platforms using those APIs. This also has the beneficial side-effect of allowing Microsoft to, with their collective first-hand knowledge of those APIs, create compatibility layers on an x86 system that can run code targeted at a different platform.

As other noted, this is not true. The early 360 development kits were literally PowerMac towers purchased from Apple.
360 games require emulation, and MS has been slowing plugging away at expanding its emulation library for years. None of this was easy.
I heard that the Xbox is basically like a PC (since Microsoft is so adept at this), so backwards compatibility is natural. But what you said about x86 architecture is interesting.
The original Xbox, Xbox One, and S/X are all basically x86 PCs, but the 360 was basically a Power Mac. Microsoft was literally using PowerMac G5 towers as early development kits for the 360.
Supporting 360 games is pretty time consuming and requires emulation. MS has been slowly chipping away at it for years.
Lots of weird incorrect answers in the comments. MS 100% has changed CPU architectures and needs to emulate old games. The 360 was basically a PowerMac.
My guess - the Xbox One’s launch catalog was trash, and MS doubled down on emulation to build it out. Then they never stopped. They kept plugging away at it, and now they have a giant asset for GamePass.
MS got a head start because they were desperate for good games in the early days on the One.f
This is the answer.
If Sony was losing the console wars, they'd be doing BC, and not MS.
The hardware architecture on the PS2 and PS3 was so radically different, it effectively makes emulation impossible.
The change made in the PS4 and PS5 makes the transfer of those games relatively trivial, but attempting the replicate the now abandoned Core processor of the PS3 is the hold up there, as is the PS2 Emotion Engine.
The reason the PS3 was so expensive was including PS2 hardware to handle the backwards compatibility. They weren't going to repeat that mistake with the 4 and 5.
Meanwhile, on the Xbox side, Microsoft never had that problem.

Software emulation is very much possible. There is software for x86 and even ARM processors that emulate PS1, PS2(doesn't work great on ARM I many cases) and PS3 (x86 only currently)which work well enough. If Sony cared to they could develop their own software emulation layer to run on PS5 to run just about everything from the previous generation.
Also Microsoft had similar issues in hardware emulation because, while the original Xbox and the Xbox one were on x86, the 360 was a Power PC architecture similar in some ways to the PS3 which ran Power PC with other proprietary coprocessors. They had to develop a Power PC emulator in software to run 360 games on the Xbox one.
A first party solution can't work "well enough", it just has to work.
PS1 emulation at this point should be trivial, 2 and 3 is not. The first time someone puts a disc in and it doesn't work would be worse for them than not having it at all.
I think the thing holding back PS1 emulation is that once they open that door, everyone will go "What about 2 and 3?"
PS1 emulation is a breeze, but with current hardware in the PS5, I think a PS2 emulator on the platform wouldn't be too insane. But yeah, PS3 emulation? Not happening.
I think you're wrong on the disc not working thing though. The original Xbox was only half supported for a long time.
I think the problem with emulating a PS1 is “don’t meet (play) your heroes”.
Most of us played PS1 on dinky little CRT screens before we got used to the graphical fidelity we have these days.
Playing PS1 games on your 65" OLED will probably hurt your eyes.
It’s one of those things that you want to do because of nostalgia, but isn’t really great when it comes to it.
Besides, at the end of the day Sony is selling every PS5 they make, just like they did with the PS4 and PS3.
Adding backwards compatibility doesn’t make any financial sense as long as it’s not a killer feature that shifts sales towards Microsoft then Sony has little insensitive to do it.
They much prefer you buy those new AAA titles or subscribe to PS+.

That really depends on the game and upscaling methods used. Duckstation for instance does a pretty amazing job of making most of those old games look good. Check out this video of Crash Bandicoot running at 4K for instance.

Didn't stop them putting out a HDMI Mini PSX. You get around that by cleaver pixel replication and filtering upressing, etc. The PS3 PS1 emulator actually had options for this.

Only if you dramatically lower your standards for what backwards compatibility means. PS3 emulators might be progressing, but they're far from the native hardware in actual functionality, especially with games that actually used the features of the hardware that made the PS3 a powerhouse.
Emulators can wave that away as "it is what it is". Sony advertising backwards compatibility couldn't.
We're almost at that point. PS3 emulation on the Steam Deck is ALMOST there. Another generation of hardware improvements should push us over the edge. Then it would be up to Sony to decide "hey, we want to make money on the titles we can license and put back in an online store...."
PS2 games work almost flawlessly on my steam deck under emulation and the PS5 is more powerful than that, and Sony have access to the OG system engineers, software and hardware to work from, note they already had PS2 games working on the PS4. The PS3 is the tricky but people do have it working on PC so no reason Sony couldn't. There's no excuse not to have PS1, PSP or PSVita emulation games as they're all easy
Xbox's Backwards Compatibility is definitely a big deal; but as someone who loves old games as a concept and has never thrown out a console, it's not as big a selling point as you would think/ hope.
I personally wanted to try some of the PS2/PS3 only games and didn't have a PS3, so I bought one used a while back. I probably only logged maybe 10 hours in it before getting completely side tracked by my backlog of modern games. And while I know that's anecdotal evidence, it really seems like the allure of classic games might not be enough of a selling point.
This is something I think Xbox had the right idea about. While BC is very useful in concept, there aren't so many classic games that would draw people away from modern games; so you only have to support those few games.
With that in mind, I think Sony could offer BC for their relevant PS2/ PS3 exclusives since they would only need to guarantee emulator performance for a much smaller number of games. I don't think it's likely for Sony to do this until they are no longer the dominant console, though, as they can make more money selling their PS3 subscription service.
From a game presentation standpoint, BC is a huge issue and I would personally love to see it happen for the PS5 (and I'd like to see it expanded to all games for the Xbox as well); but I doubt there would be much return on investment for developing the BC features, and that's the only motivation for corporations.
You're absolutely right. However I will add to your initial point. If I could have paid an extra $100 - $150 (for the hardware) in order to have PS1-PS3 games play on my PS5, I would have just so I could have it as an option. Bonus points if the entire PS3 digital library (especially the PS1 classics) were still available.
Not the original commenter, but I did pay the extra $100-150 for the PS3 for backwards compatibility. In retrospect, I shouldn't have. I played maybe like 3 PS2 games on it. I was far more interested in then current-gen games. I sorta got swept up in the hype of BC back in the day, especially when Sony stopped production of BC PS3s. I literally ran out and got one before they all disappeared; I still have it.
Looking back, the option wasn't worth it. But we're different people, different consumers. Our needs and wants differ.
It's because backward compatibility would cannibalize the sales on new games. Same reason Nintendo limits releases of old games. If you have an extensive back catalog of games, then new games are less appealing.
Or you do what MS does. Put the old games in your subscription service. Make money with monthly fees from people who don’t have the disks or don’t have an optical drive.

The simplest and most likely reason is just because they don't have to. Playstation is leading Xbox by a lot this generation (so far, things can change) and PlayStation just has no incentive to add value to something they're already selling record numbers of. Xbox is trying to attract customers, customer playstation has left on the cutting room floor, and backwards compatibility is a way to do that.

Money
This is part of the reason why I haven't thought of buying a console since the PS3. There are a lot of games that were made for the ps2/1 that I really loved and I can probably never play them again because PlayStations lack that feature. They have effectively been erased, which is really sad.
I sold my PS3 a long time ago, and I've been using Steam on my PC since then. Now I won't have to worry about losing access to titles I bought just because they're locked to certain hardware that will eventually not be made any more.

lol, I’d rather have the first party modern bangers Sony’s pumping out then…checks notes…literally no good first party games on my xsx since I bought it. Backwards compatibility is great, but I don’t spend $600+ on a console to play old games. I can keep my old consoles around for that or emulate.
Depends on your tastes doesn't it. I'll take a hundred smaller projects like Pentiment, Hi-Fi Rush or Psychonauts over another generic open world adventure or sad dad simulator.
I have all there of those on my PC/Steam Deck. They're not really XBox exclusives.
They're Xbox console exclusives, don't be disengenuious.
I wasn't being disingenuous... I can and have played all of those games and I have never owned an XBox in my life. That's not exclusive.

Pretty sure the PS5 drive can't actually read CDs, so that's the PS1 library and most early PS2 games gone right way, even though they can be emulated pretty easily. The PS3 should be possible, but they haven't bothered when you can play it streaming.
I guess the awkward truth here is that there's no real business need to have it. Most of us into retro games will have a way to play them already, either via PC emulation or old consoles. And if you show a Gen Z kid some of the horrors we used to enjoy on PS1 (although I maintain Sheep, Dog 'n' Wolf is an underrated classic), they'd run screaming back to Fortnite and CoD.
It would be nice to have it, but nobody is not buying a PS5 because they can't run Terracon. They're still selling them as fast as they can make them, even with the economy in shambles.
I remember when Sony announced they were stopping production on backward compatible PS3s. I ran out and got one, because I still had PS2 games I wanted to finish. The BC PS3s were more expensive than their non-BC counterparts. And the PS3 was already an expensive machine.
I think I played 2 or 3 PS2 games on it. And never with consistency. Plus, these older games looked terrible on modern HD screens. And frankly, I was more interested in playing current gen titles. For example, I got a PS5 so I could play FF16. Not so I could keep playing FF15 or FF13. It really ended up being a real waste of money to buy that more expensive PS3.
And many of the games eventually re-released on other platforms: PSP/Vita, Steam, Switch, later-gen consoles, etc. I play a lot of JRPGs, so that helps.
Backwards compatibility is something I really don't care about. It'd be nice, I guess. But I still have my PS3 and PS4. If there's something I really want to play, I can boot those up. Or just see if the game is available on Steam.
A while back I bought Metal Slug 3 on the ps4 for super cheap on sale. It was just the ps2 version emulated. So Sony has a PS2 emulator
They're perfectly capable of running old games, they proved it times and times again. They just don't want them to be backwards compatible so you have to buy them again.
I wish Jet Set Radio Future was able to work on the new Xbox.
Many suspect this one has been trapped in licensing hell.
