PS5 focus is high performance, not high power. Are people underestimating the value of the approach?

Below is one example where custom hardware was used to resolve a bottleneck and in the process save one whole CPU core. (Meaning it could be used elsewhere) When Mark is quoted as addressing all bottlenecks then that would be where the excitement from devs is coming from.
IF similar bottlenecks are resolved on the GPU side then that means you won't need as many teraflops to perform the exact same operations as XSX.


For PlayStation 5 our goal was not just that the SSD itself be a hundred times faster. It was that game loads and streaming would be a hundred times faster so every single potential bottleneck needed to be addressed and there are a lot of them.

Let's look at check-in and what happens when its overhead gets a hundred times larger conceptually. Check-in is a pretty simple process, data is loaded into system memory from the hard drive or SSD it's examined a few values are tweaked to check it in and then it's moved to its final location at the SSD speeds.

We're talking about that last part moving the data meaning copying it from one location to another takes roughly an entire next-gen CPU core and that's just the tip of the iceberg, if all the overheads get a hundred times larger that will cripple the framerate as soon as the player moves and that massive stream of data starts coming off the SSD so to solve all of that we built a lot of custom hardware namely a custom flash controller and a number of custom units in our main chip the flash controller in the SSD was designed for smooth and bottleneck free operation.

I'm not saying PS5 is more powerful than XSX because of these changers but it obviously at the very least brings the two much closer together performance wise since PS5 is using (as per Mark Cerny) 'a lot of custom hardware'.

Better image , also if Xbox SX GPU is going to get to 52(56) by having 7 Dual Compute Units in the sections where RX 5700 XT has 5 that would give PS5 the advantage for everything outside of the compute units from having the higher clock-rate but we don't know if that's the way Xbox SX GPU will be designed

You guys need to start posting in the same thread.

It's not that I disagree with your premise, but we don't need 100 threads all saying the same thing in different ways. Add to and create an interesting convo with lots of different points on the subject.

Xbox has the same, though. Also, did this really warrant a new thread?

"DirectStorage can reduce the CPU overhead for these I/O operations from multiple cores to taking just a small fraction of a single core"
 
No i don't think they are, most of us on here know its going to be absolutely fine, and hardly any different to the XSX when it comes to the comparisons, most time resolution. It's just peoples ego's that don't like the fact that Sony got beat by XBOX with the power.
They'll both be a great.
 
This is to quell a bottleneck in data streaming. This in no way, shape or form will resolve better performance from the system itself but merely alleviates a potential detraction in performance.

The CPU is the CPU, the GPU is the GPU, the RAM is the RAM, and nothing will change their configurations.

Downplaying a legitimate revolution in SSD technology is never a good look.

I'm a Sony fan but totally agree

There are already numerous SSD and "praise Cerny" threads though.

Mod's need to step in, this crap is getting out of hand. Basically the whole first page is turning into PS5 damage control.

Again with the labelling and dismissive attitude.

No one is saying you guys don't have a fast SSD, but there's a difference between a Ford and a Ferrari ;)

So Ford is Xbox?

Mods should really merge all these threads together. Beating a dead horse over here with the same shit.

Just buy your little plastic box and shut up already lol

No, just no! I need my daily "9 is the new 12" and "Warner Bros. should forget about The Flash and make a Sony SSD Series" threads.

Please requote where they state addressing all the bottlenecks.

What a disingenous way of debating. It really is damage control time these days. Especially considering your thread is also revolving about a huge "IF".

Xbox has custom hardware designed to remove bottlenecks from the system, just as Sony has.

Yeah, like I said he's posing a leading question looking for a very specific answer that he knows you can't provide thus what you're alluding to must be inaccurate.

You're not getting what Mark Cerny said.
 
TBiddy TBiddy and DynamiteCop! DynamiteCop!

I'll gift you both one month of GAF Gold if you provide us actual evidence that Xbox's SSD is at the same level and class as the PS5's SSD in terms of levels of optimization, elimination of bottlenecks, perfomance, and sheer raw compression speeds.
