Apparently Microsoft just commited suicide according to our insider here.
It's not like he could've known about the special structure of the memory. He thought 13GB like it would be for a PC, but that's not really the case.

"Memory performance is asymmetrical - it's not something we could have done with the PC," explains Andrew Goossen "10 gigabytes of physical memory [runs at] 560GB/s. We call this GPU optimal memory. Six gigabytes [runs at] 336GB/s. We call this standard memory. GPU optimal and standard offer identical performance for CPU audio and file IO. The only hardware component that sees a difference in the GPU."

In terms of how the memory is allocated, games get a total of 13.5GB in total, which encompasses all 10GB of GPU optimal memory and 3.5GB of standard memory. This leaves 2.5GB of GDDR6 memory from the slower pool for the operating system and the front-end shell. From Microsoft's perspective, it is still a unified memory system, even if performance can vary. "In conversations with developers, it's typically easy for games to more than fill up their standard memory quota with CPU, audio data, stack data, and executable data, script data, and developers like such a trade-off when it gives them more potential bandwidth," says Goossen.

Xbox Series X supporting 802.11ax/Wifi 6 is excellent news. But the Series X supporting VR with a wireless Wifi Direct VR headset would be a dream come true.

If Microsoft doesn't want to build a headset themselves, they should atleast partner with either Oculus, or Valve, or both and announce that the Xbox Series X will be compatible with those headsets. Being able to pair my Oculus Quest (and it's eventual 4K successor) with the Xbox Series X would be absolutely fantastic.


A $500 system powerful enough for 4K VR will sell like hotcakes. The Series X has the horsepower to power life like VR environments.

Where's that information?

please

This video is amazing. Thank you for sharing. I just wish DF talked more about the wifi chip. I remember reading that it has 802.11ax. Is that true?

DF, if you are reading, please tell us more about the capabilities of the 802.11ax? Wifi chip in the console.

What resolution could this chip theoretically stream at 90fps using Wifi Direct.

Could 802.11ax stream enough data via wifi direct to output to two 4K displays (one for each eye) at 90hz for the Oculus Quest 2 successor or Valve's eventual Wireless alternative. The Series X supporting VR with a wireless Wifi Direct VR headset would be a dream come true.

"RDNA 2 fully supports the latest DXR Tier 1.1 standard, and similar to the Turing RT core, it accelerates the creation of the so-called BVH structures required to accurately map ray traversal and intersections, tested against geometry. In short, in the same way that light 'bounces' in the real world, the hardware acceleration for ray tracing maps traversal and intersection of light at a rate of up to 380 billion intersections per second.

"Without hardware acceleration, this work could have been done in the shaders, but would have consumed over 13 TFLOPs alone," says Andrew Goossen. "For the Series X, this work is offloaded onto dedicated hardware and the shader can continue to run in parallel with full performance. In other words, Series X can effectively tap the equivalent of well over 25 TFLOPs of performance while ray tracing."

It is important to put this into context, however. While workloads can operate at the same time, calculating the BVH structure is only one component of the ray tracing procedure. The standard shaders in the GPU also need to pull their weight, so elements like the lighting calculations are still run on the standard shaders, with the DXR API adding new stages to the GPU pipeline to carry out this task efficiently. So yes, RT is typically associated with a drop in performance and that carries across to the console implementation, but with the benefits of a fixed console design, we should expect to see developers optimise more aggressively and also to innovate. The good news is that Microsoft allows low-level access to the RT acceleration hardware."

Where does it say XsX has wifi 6?

So, github was wrong about seX after all?

well no... we don't know if the github chip had more than 56 CUs
we just know that the active CUs changed, which is something that can change up until the last minute theoretically (not practically because that would throw off developers)

Awesome stuff ... looks great!

Great to see Microsoft not afraid to tell it like it is.

it’s always interesting to see the marketing teams frame their products against others .. Sonys marketing was very much around SSD speed and 3D Audio... presumably trying to push the importance of those features and proactively counter MS capabilities.

From that video MS seem to be suspecting Sony might have variable clocks, potentially inconsistent performance or heat problems if they push too hard. Be interesting if Sony feel they need to win the numbers war and push to end up with slightly better specs. Only after release will we see if that pans out to anything or Sony engineering overcomes any issues with higher clocks.

Xbox soc not as huge as suspected.

i suspect ps5 to have more RAM and to a slighty faster SSD but everything else will be similar...price slightly cheaper for Xbox.

Performance of both consoles will be very similar. everyone wins! ( apart from forum fanboys)

Just need to remind you things that i said before for the last time\
GPU: PS5>SeX ~10%
RayTracing Accelerators: PS5>X1 (PS5's RT works by using acceleration structures and algorithms much like nVidia's RTX cores)
CPU: Sex>PS5 ~ 6%
Memory: PS5>Sex for the size and bandwidth
SSD: PS5>Sex ~ Over twice as fast (this is the biggest and most noticable difference)
Fan noise (Dev-Kit): Sex>PS5 (not as egregious 1x vs. Pro).

BTW it's up to you believe me or not, but things gonna be clear very soon and you will find out who knows and who knows shit.

Bonus?
Remedy and Housemarque have been in Sony's WWS family for a while now!

Techland belongs to MS now!
He posted this on January 23rd. So 10GB/s read for PS5?

Also from https://news.xbox.com/en-us/2020/03/16/xbox-series-x-glossary/

SDR to HDR Conversion – With Xbox Series X, existing Xbox games, including recent titles within the ID@Xbox program, that don’t already have native HDR support will get the next-gen treatment. Xbox Series X is able to leverage an innovative HDR reconstruction technique to enhance existing SDR games with no work from developers and no impact to available CPU, GPU or memory resources.

Xbox Series X Storage Expansion Card – Built in partnership with Seagate, this 1 TB custom storage solution expands storage capacity of Xbox Series X with the full speed and performance of the Xbox Velocity Architecture Previous generation Xbox titles can still be played directly from external USB 3.2 hard drives. However, to receive all the benefits of the Xbox Velocity Architecture and optimal performance, Xbox Series X, optimized games should be played from the internal SSD or Xbox Series X Storage Expansion Card.

It is an expansion slot on the back

If he thought that it would make no sense since consoles memory was never like PC memory because it unified .
Seem like MS did even more extra stuff but the point remains the same .
