The fish are cases when pages in system memory are updated by the CPU, GPU or SSD and the caches being used by the GPU have to be either completely cleared, or just the bits that have been modified can be snipped out instead.

It was late and I wanted to make it intentionally wacky to drive home my point that it's just an analogy to convey the kind of concept Matt was talking about for someone that perhaps wanted an appreciation of it while not being able to understand the technical side of things. Analogies can always be taken too literally and stretched too far, so by making it this silly it's more difficult for that to happen.

Something a bit closer to reality would be two different mathematics factories exploiting child labour, where one has 36 desks of kids that can do 223 calculations per minute per kid, and another has 52 desks of kids that can do 182 calculations per minute per kid.

If everything about how the factories were laid out and run was equal, then you'd be able to compare their peak number crunching output by multiplying amount of desks and calculations per minute.

Each kid (CU) sitting at a desk (cache) has to get up and go and get a new list of sums from the next building (system memory) whenever he has finished what he has been allocated.

Sometimes a manager will come in and confiscate the list of sums from a kid that was working on them, and tell them it's out of date, and that they should go and get an updated version of that list from the next building and then carry on from where they left off.

In the factory with 36 kids, they walk to the next building to get a new list of sums at 4.48mph all of the time.
In the factory with 52 kids, they walk to the next building to get a new list of sums at an average speed somewhere between 5.6mph and 3.36mph.

Do the simple math on these two identically run factories of kids and how quick they are and the factory with more kids brute-forces its way ahead, despite having slower kids. More number crunching, good.

But what if the factory isn't run the same?

What if in the factory with 36 kids the manager doesn't come in and confiscate a list of sums currently being worked on, but just leaned over the desk and crossed out the one that is out-of-date on that list so the kid could keep working?

Then you can't just multiply kids by kid calculation speed to compare the factories.

It also means you can't really compare the speed at which the kids walk, if in one factory the kids have to be walking a lot less. If you're slower at walking, but don't need to walk as often, you spend less time walking overall, and so don't need to walk as fast to do the same amount of work.

It also means for a given amount of kids sat at desks, you get more sums crunched under this type of management. It's more efficient to the point a 36 desk factory will perform closer to a factory ran the old way with more desks.

A bit less fishy, now!

What I don't know is how often GPU caches get invalidated in typical game code. What I don't know is how much difference this actually makes in typical game code. A 36 CU GPU with Coherency Engine & Cache Scrubbers performs like a ?? CU GPU working the way things have always worked.
It could be a tiny efficiency gain that's nice to have, or it could be really significant.

Matt seemed to suggest that it's more significant than people realise, especially as the time available to render a frame get smaller at higher FPS.

It could be that XSX scales better at higher native resolutions and PS5 scales better at higher frame-rates, which is more critical to something like VR.
It could be that in typical game code the difference in performance between the two is significantly less than the 15-18% difference you get just by counting CUs and clock-speeds and ignoring the faster and more efficient caches. All of this is conjecture and something I don't know and am not qualified to predict. I'm excited to see how it pans out.
In my opinion this doesn't mean the PS5 GPU has now closed the gap, but from what Matt was saying the gap might be not only smaller than some people are throwing around as fact, but that in some scenarios of graphics rendering the PS5 GPU is actually better.

I don't think either side is getting particularly short-changed on graphics this time around, but that's just my hunch, and we'll all known soon enough.

so what was is again that compelled you to use child labor instead of say... regular labor in this example xD

nice explanation though :)

The internet is not going to be kind to any focus on indies, CGI, virtual storybooks or long winded pats on the back. This thing has to be lean and delivering bombs else... the Great Nerd Riots of 2020 will commence.

Seriously, though. They better be ready to deliver cause the gaming public has amassed chronic blue ball syndrome and it could get ugly if there's no full release.

I would set up a comfy booth with Insane Metal Insane Metal , the immortal Tesseract Tesseract (to hopefully absorb some of his knowledge), and then anyone who I have ever pissed off on here so I can show them I am not a bad guy.

edit

Also I would have to thicc_girls_are_teh_best thicc_girls_are_teh_best there with me so he can explain the technical stuff I don't understand

So, talking of Dead Space,
I know they're on XB1's EA Access subscription (and likely not on PS4's EA Access due to BC situation?)

If I was to buy the 360 games digitally outright off the Xbox Marketplace Store, would they work on my XB1 through BC? Or does the possiblility exist for a game to be available on EA Access, but not BC?
 


I don't know but my prediction that maybe Sony santa Monica new game not god of war 2 , I have felling that there new game is third person sc fi co developed by new Sony studio in San Diego and written by that dead space writer

As hyped as I am for the show tomorrow and I am and I hope it is everything I want it to be (New Games, Console Reveal, Release date, Price, Pre-order) I want it all.

But I would be lying if there wasn't a small part of me that would derive no small amount of pleasure from the ensuing shitstorm that would ensue if they only showed half a dozen or so Cinematic trailers with only 1 or 2 exclusives announced and no console info.
