Full BC on PS3 (proven via Jailbreak) *spawn

well ... no
Memory technologies quickly evolved between PS2 & PS3 (like many other technologies in this time-frame). But the Jump to PS4 was well... quite a minor one. Memory size yes, but everything else, no.
Also edram is quite easy to emulate, it is fast, but one that is really slow in answering.
Well maybe in 8-years after PS4/xbox one we have something similar on the horizon, but I don't see this kind of technology soon. HBM3 might have enough bandwidth to emulate 32mb of really fast memory.
No it wasn't. The PS3's backwards compatibility was made possible by including the PS2's graphics chip in the console. When the Graphics Synthesizer was removed, backwards compatibility with PS2 games was lost.
How did the launch EU consoles work with at least part software solution, we got short changed on BC.
The original PS3 consoles effectively had an entire PS2 inside them. The EU consoles removed the Emotion Engine, emulating it on Cell.
Jailbroken PS3s can play every single PS2 title. Look it up on YouTube
Digital Foundry had an article on it (minus jailbreaking)

Apparently there is still some slowdown in some cases, but case in point: the difference between Xbox one esram and gddr5 is extremely small compared to ps2 edram and ps3 its 22GB/sec gddr3

Sorry, I couldn't find the video where it shows that a jailbroken PS3 can play "every single PS2 title". Could you please provide a link?

After my PM, decided to spawn off a thread.

Isn't the emulator using the Cell for this? It has local stores running at ludicrous speed. It's almost like 2MB of registers, and it could fetch from XDR too, or even feed the GPU directly through yet another very fast pipe operating independently. I don't know, it seems apples to oranges to compare PS2's VRAM with the PS3's GPU access to GDDR3.
You guys are missing the point:
-PS2's 48GB/sec 2048 bit wide (or 1024 I forgot) DRAM frame buffer being 'emulated' on the 22.8GB/sec GDDR3 PS3.
The fact that all games 'work' shows us that there is most probably a full software solution in place, instead of a 'per game modified to fit inside PS3'- kind of deal.

So how is the emulation done after all?You want to read up on the "BC on PS3" discussion(s) where fafalada (?) explained BW was the least of the problems, and went into detail why. Some here. Look for the rest yourself.
Clever programming.
Nope. And certainly not this coming 2017 will there be hardware that can properly emulate Xbox One.
PS2 emulation on PS3 could not be done either. And yet here were are.
Guess we'll just have to agree to disagree
It makes you think: If the software emulation solution was done in 2006 (how impossible it might seem) then (even half arsed like Xbox 1 emulation on 360) it could have saved Sony a lot on manufacturing costs. PS3 would have been cheaper from the start, and thus number one and as a consequence PS4 could have ended up being the Xbox One of video game systems...
With PS4.5 being unable to emulate PS4. Guess it was all meant to be. The gaming gods probably planned for all this from the start.
Imagine being Don Mattrick, recently being promoted to king of Xbox One prototype division... he could not known what they had in store for him

I don't know my playstations well, but how many GFLOPs is a PS2 and how many is a PS3?PS2 emulation on PS3 could not be done either. And yet here were are.

What Mhz does the PS2 run what does the PS3 run?
How many is a Xbox vs the next Xbox?
Will the two ratios be equal? in both clock speed and flops be the anywhere close to the same?
edit: nvm.
PS3: 3.2 GHz CPU- 230.4 GFLOPs GPU
PS2: 300 Mhz CPU - 6.2 GLFOPs GPU
10:1 on CPU 37:1 GPU
Xbox One: 1.75 GHz / 8 cores - 1.3 TFLOP GPU
PS4 Neo: 2.1 Ghz/ 8 cores - 4 TFLOP GPU
1:1.2 CPU -- 1:3.1 GPU
I think the numbers speak for themselves.
