Very surprised to see this. I would have thought the PS5 SSD was much faster. Thanks for posting (:

PS5 / XSX Backwards Compatible Load Time Comparisons
- Thread starter Raigor
- Start date
Yeah, the XSX numbers filled me with hope and this is a let down. I really hope its not an omen for PS5 games; though, Demon's Souls makes it seem like everything is gonna be good.
Complete speculation, but it could be that old-gen games are just suited better to how the XSX SSD works/setup?
Thinking out loud here.
I'd take a stab at this relating to how BC is handled.
Sony switched their default/standard compression library between gens, and is likely letting PS4 games simply handle loading and decompression on the CPU as before.
Microsoft stuck with zlib, and for games using zlib, is likely passing them through the decompression hardware in XSX, which may be end up the faster path vs a CPU path on PS5.

I did some loading test comparisons as well. It's definitely faster than the PS4, no doubt, but it's not as fast as the Xbox Series X. I put it down to the implementation of the BC: https://www.pushsquare.com/news/202...atibility_-_the_good_the_not_bad_and_the_ugly
At the end of the day, though, ultimately you're probably going to want your PS4 games on an external HDD as there's just not enough space.

It loads the open world instantly
These loads are BC only, hopefully they improve it because loadings suck.
Even if it's not using all the bells and whistles of the velocity architecture, maybe there are passive benefits that come with the pipeline; or, maybe Sony throttled the SSD for compatibility's sake. I don't think a .2 difference in CPU speed should really account for that much, but I'm not an expert there.
Digital Foundry does not agree with you

There's no twist lol, this happens in BC games for some reason.
peak speed is just that, peak speed. You still need software to take advantage. (Microsoft has big advantage there).
Your wrong, The BC is very good just seems like xbox may be better and that was expected.
Ultimately, loading times has become a software issue more than a hardware issue. Some old practices (eg using a single CPU thread to handle loading requests, using the CPU to decompress files) are going to have to change pretty radically to tap into the new speeds. Needless to say, this won't happen retroactively for older titles.
What? DF just did a video showing that in many instances BC is even better than on the XSX. Are you also dissappointed about XSX BC?
Does it really matter? They are both well quicker than we had previously.
Did you expect backwards compatible games to load slower? I surely didn't
Wow that's surprising.
Velocity Architecture isn't used in BC games.
Complete speculation here but I think you're right. The XBox seems to have nailed BC.
Also if both SSDs provide comparable performance for the most part, that's great news for multi plat games of the future!
Not the API, but the system may - for example - be passing things like zlib decompression through hardware parts of 'velocity architecture' for maximum improvement. Something like that could explain a difference in BC games, if Sony is not doing similar (and they couldn't for zlib-compressed data anyway on PS5).

This. This really belongs in the DF PS5 thread, but two specific things will make PS5 games better in BC than Xbox here. For mid-gen upgrade games, if the Xbox 1X version was dynamic 4k or 4k itself, and the PS5 version was 1440p, checkerboarded etc, the PS5 version will have a better chance of hitting 60fps. The other thing mentioned in the Digital Foundry video is that if that base PS4 vs Xbox games ran at a higher resolution to begin with, non-upgraded games will look better on PS5.
Companies tend to talk up their strengths. Microsoft has talked about back-compat so much that it was obvious that they knew they were in a better position.
Compare to Sony - what piece of hardware did they show very early? The Dualsense and all it's haptic stuff... because it is a major strength for them.
No, but I think it's a thing they'll surely fix. The way Sony ignored BC I wasn't expecting games locked at 60 either.
Cool both seem to be fast, thats awesome. Though xbox does seem to have a slight lead in these games, its still early days, ill be more interested to see how next gen titles load across both, same with asset streaming. Regardless, its silly to gloat over a few seconds. Lets be chill.
True, still, I'm quite surprised that series c loads these faster hence "twist"
And this morning I would've bet good money on valhalla loading sigmificantly faster on ps5 now I'd be a little more cautious
1. Many games are 900P on Xbox One vs 1080P on PS4. Games will run on the same resolution with BC Mode, so games that where 900P on Xbox remain 900P on X Series X. Both obviously run at locked 60.
2. Many games use Reconstruction Tech on PS4 Pro and don't hit native 4k or 1800P like the One X version. Those game all run on locked 60 Frames while it can dip to 52 frames on the Series X like shown on Sekiro.
Fantastic but not as good as XSX is a disappointment to some people for some reason.
What does that mean?
Some games run smoother and others run at Higher Resolution than on the Xbox. Call it what you want.
If you don't want my word, take it from John from DF
Load times of new games should be the more interesting comparison considering Microsoft have put far more effort into their BC than Sony.
Not that we know of. Its just base 12Tf of GC GPU power, not even RDNA2 stuff either and no XVA.
