Xbox Velocity Architecture: A Closer Look at the Next-Gen Tech Driving Gaming Innovation Forward on Xbox Series X
- Thread starter Theorry

Microsoft have done an admirable job marketing all these different aspects of their console. Reminds me of Apple marketing high DPI displays with Retina.
But that trailer on their page is giving so much dudebro-power-speed! vibes that I cannot help but laugh.

It's def interesting approaches, the Sampler feedback is very interesting they seem to have a way to help with just in time loading of textures which they say can free up memory it sounds like a big deal there where effectively acts as a multiplier for available memory.
I don't know one way or the other but if I recall correctly Cerny used peak figures for the GPU and CPU so it's not outlandish to believe be used peak figures for SSD. Couldn't find any concrete data one way or the other so you're guess is as good as mine.
Iirc Cerny did not say they were peak or variable like their CPU and GPU. Xbox is emphasizing the difference of their GPU/CPU not slowing down like the one in the PS5 or throttling like PC SSD's.
Lol Xbox and Phil contradicting each other constantly with their message.
"level designers are still often required to create narrow pathways, hallways, or elevators to work around the limitations of a traditional hard drive and I/O pipeline."
Meanwhile Phil says PC architecture proves everything is scalable and weak and old hardware are not holding anything back.

ayyyeeee
SFS provides an effective multiplier on available system memory and I/O bandwidth, resulting in significantly more memory and I/O throughput available to make your game richer and more immersive.
:O
Traditional SSDs used in PCs often reduce performance as thermals increase or while performing drive maintenance. The custom NVME SSD in Xbox Series X is designed for consistent, sustained performance as opposed to peak performance. Developers have a guaranteed level of I/O performance at all times and they can reliably design and optimize their games removing the barriers and constraints they have to work around today. This same level of consistent, sustained performance also applies to the Seagate Expandable Storage Card ensuring you have the exact same gameplay experience regardless of where the game resides.

I think they're just captializing on the confusion about PS5's variable clocks. Cerny didn't say anything about variable transfer speed that I can recall.

Nice to also have confirmation also that there is no secret sauce as people have speculated about for some reason.
I mean, can we just not do this sort of thing.
Unless of course you've used both and compared them.
This is the secret sauce. Using various new technologies to boost the overall performance of storage, memory and the entire I/O.
I recently rewatched the Cerny presentation and this sounds pretty correct
Just to clarify, SFS is supported on current Nvidia GPU's along with RDNA2 GPU's and is not specific to XSX.
It's a shame these trailers are releasing before the July 23rd event, all the game footage they use to illustrate the points is so underwhelming.
Even in quotes it's wrong
Cerny said 5.5, with 8-9 effective while factoring in the Kraken hwa decompressor.
I 100% guarantee you they're stressing sustained as a vs. PC thing, as PC SSD's have issues with sustaining their speeds currently. PS5 should also be able to sustain its speeds.
Neither. It's 2.5x the raw hardware speeds still. It doesn't compound with the compression speeds. This works in conjunction with that. You still need to decompress but with this they are saying you can be more selective thus needing to load less into the memory.
It's what Cerny said, though I was wrong and it's actually 9:
From: https://www.eurogamer.net/articles/...s-and-tech-that-deliver-sonys-next-gen-vision:
"By the way, in terms of performance, that custom decompressor equates to nine of our Zen 2 cores, that's what it would take to decompress the Kraken stream with a conventional CPU," Cerny reveals.
So 16GB of GDDR6, 10GB GPU memory.
Are they doing a split pool again?
Assuming this means it's 6GB of whatever and 10GB of GPU memory. Or is it 16GB of GDDR6 and then 10GB of whatever they're using for GPU, since the transfer on the GPU spec, there, is a lot higher (assuming it really means GB and not Gb) than normal GDDR6.

he was referring to the compression ratio. In principle for data that compress at least 4:1 you can saturate the controller and reach the 22GB/s figure.
Thermal throttling is another story though
Sony's speeds are sustained as well. Cerny was upfront about their variable speeds on the gpu and cpu they wouldn't just leave out the memory being variable if it was.
Sony said that, or there abouts... I think they compared it to 9 zen2 cores doing decompression work.
He did actually. He contrasted it with varying bandwidth on a HDD depending on location.
The whole thrust of his talk was about a dependable, predictable bandwidth. Given it's built into the motherboard, it should have plenty of cooling.
not sure of the relevancy to your reply? im just highlighting a feature that is coming to the series x that was noted in the article.
Wrong, Sampler Feedback is in RDNA and Nvidia, SFS is specific to XSX and requires specific hardware.
We known about all of this for months now but people were speculating there were holding other hardware improvements hidden. This is nothing new and nothing that in anyway bridge the gap in performance compared to the PS5 as some speculated it would when everything was revealed.
I was just adding clarification to anyone thinking this was an XSX specific feature, not necessarily directing it at you. You simply had already highlighted the relevant portion from the article so I piggybacked off your quote.
