More power? Or Full Backwards compatibility?

As a game Collector I would love for the PS5 to be fully backwards compatible with every console Playstation.

I currently have a PS2, PS3, and a PS4 hooked up to my TV. (Would love to get the OG PS3, but they are getting hard to find, and they are not reliable)

Having a PS5 with 1-4 BC would clean up my entertainment center, and provide a solid way to play my older games. One negative with OG hardware is that....well...it's old stuff. Old stuff will break, and as OG PS1 and 2's get older it's going to be hard to fix/replace them.

If I was picking up PS5, (which I'll eventually will in the distance future) I want absolute POWER! BC means nothing to me and I always keep my oldie consoles anyways. PC's BC however, it's just their. 13 tflop, let's go all the way up and it wouldn't be next-gen console if you wasn't gonna improve your console right?

Power always.

Good games.

POWER

Full on BC for sure.

Would mean much more to me if it were a fully BC Nintendo console (yeah, some wii and especially wiiu games would be an issue), but I'd buy all three of the next boxes day 1 if they were BC.

If Sony could bridge PS3's PS1/PS2 BC library ownership and expand on it, and carry rights over, and not rely solely on PS Now, I would opt for the BC option.

Full BC.

Full backwards compatibility for me.

Flops for me. I only have PS4 games right now. I don't plan on rebuying or replaying games before the PS4.

Look, I'm all for full backward compatibility, but overall I would rather have more power. I own a LOT of old games, but I also still own the consoles those games released on. That said, I am anticipating the PS5 more at this point in time. Doesn't really mean much though, because I'm sure I'll split my time among everything like I always do.

@r-gamer:

NAVI 10 has support for the new wave32 and GCN wave64 legacy modes.

Wave32 instructions are processed with 1 clock cycle.

Wave64 legacy instructions are processed with 2 clock cycles.

----

GCN process wave64 instructions with 4 clock cycles.

NAVI 10's wave32 has similar length as NVIDIA CUDA's warp32.

NAVI is still GCN instructions with wave32 compute payload length.

My point, GCN legacy support is not a problem for NAVI.

My point, removing wave64 support wouldn't make a huge difference with NAVI.

BC for sure. Rather play enhanced old games than some Dad of War 2 movie.

And how is this related to the actual thread itself?

BC that few % wise of performance won't be noticable they would get without a api.

BC anyday and everyday. I don't want all these redundant hardware connected to my TV. In fact I would prefer just having on device.

Also Ron doesn't know what the hell he is talking about as usual.

I would love to get rid of the pile of systems under my TV. I also have to note it's of course going to have more TFLOPS than the PS4 anyway - so yes, I value full BC more than the specific TFLOPS number. MS can win that title - don't care - what will sell me a PS5 is its games and an ability to play my old PS favorites to boot

Uhhh? The more flops the easier it should be to make things compatible. I voted for BC.

The PS5, if they insist on having exclusives, should be a high-end computer that plays games from all previous generation. Damn the expense!

Whatever they have made is not powerful enough. Whatever backwards comparability solution they have created is not good enough. I'm hard to please tho :)

BC always. With more power, you’re just going to be playing boring tech demos for 2.5 years before anything good comes out.

No need for BC for me,but it seems that the majority wants BC. I would want more power to my console,but that's just me.

I don’t care about backwards compatibility. Especially if its holding hardware back

More power... I don't want to play PS1-PS4 titles on my PS5. I want remakes on the PS5.

My point, GCN legacy support is not a problem for NAVI since RDNA still runs GCN instructions with shorter wave32 compute length and improved branch hardware.

Also Pedro doesn't know what the hell he is talking about as usual.

I already have both. Not interested in PS1 or PS2 games, but can emulate them nonetheless.

Wow, most people shouldn't bother with next gen or even current, just want to play old games. There are hardware solutions for that released a long time ago.

Silly question IMO.

If PS5 is 10TF on navi arch...it's already poweful!

11 or even 12TF will not make much difference in overall performance on the same same arch.

What you'll get maybe an extra extra 7 - 12 frames with EVERYTHING else being absolutely the same but still able to run most games 60fps 4k or 1800p? LOL yeah that's a BIG deal? NOT!

So to answer 10TF on navi is already "powerful" and having the ability to play all PS gens wrapped in 1 system is a PRICELESS feature that a few extra frames could never make up for!

PS5 with completely BC is a win win on power and software compatibility.

Neither

Ask the cow fanboys on SW,it’s

Console Sales

Revenue

Exclusives

Power

Features

But that’s obviously fanboy damage control

BC is just a cool feature,the correct order(if you have more than 1 brain cell) is

Games

Power

Price

Features ie gamepass-ps now

The rest is the concern for the companies

More power, chose the wrong option.

lol this comment will age well 😂 and extra points for accuracy!

RDNA @ 12 TFLOPS difference with PS5's 9.2 TFLOPS or 10 TFLOPS is dependant on how RDNA GPU's Shader Engine layout and memory bandwidth configuration.

If XSX' GPU has the following config

384-bit bus GDDR6-14000 = 672 GB/s (320 bit GDDR6-14000 was shown in E3 2019 and it's not full PCB reveal)

1700 Mhz, Three RDNA Shader Engines (SE) with each SE having 20 CU, hence ROPS count would be 96 ROPS.

57 CU active with 12.4 TFLOPS (3 disabled CUs)

56 CU active with 12.18 TFLOPS (problematic configuration, not equal CU deactivation among the three Shader Engines, 4 disabled CUs)

Result: scaling would be nearly straight

PS, 20 CU per RDNA Shader Engine already appeared with NAVI 10.

I don't see any reason why it couldn't do both.

More power, AND full PS4 bc. I wouldn't mind PS1 bc, love the console, but couldn't care less for PS2 and PS3 bc.

With great power comes great compatibility?

without a doubt more power, ps4 games bc is fine, why on earth anyone would prioritise playing ~7 to 20 year old games over new ones that can take advantage of better hardware i don't know

Cause the new ones aren't that good. :)

@pyro1245: No, but I don't think it would be especially hard to do for Sony. Then again, I'm not a programmer..

I want the flops I can play emulators on PC so I'm good.

current ones ;)

In my experience very few games utilize the full power available to them on either console or PC--game engine development is expensive both in terms of money and time, after all--so I'd rather see backwards compatibility supported.

full on BC please

Full BC. The next gen systems will be weaker than my 2 year old PC anyway. Then at least give me somenice gimmick like full BC (which includes UMDs and Vita cards)

Power after a while the graphics get so bad I find them unplayable especially with the ps2/1 era games.
