It's getting ridiculous. Doubling the bandwidth is good but if it's harder and harder to build, what the point. They could have done that years ago.
I guess they can give pci-e 5 to the gpu (first slot), and then still stay in pcie4 for the rest ?
that suggests there won't be any consumer level PCIe5 drives available to take advantage of it.
It's not just about the availability of PCIe 5.0 lanes in the host CPU. If you look at Marvell Bravera SC5 specs above, they include no less than 10 (ten) ARM Cortex-R8 and Cortex-M7 cores dedicated to LBA sector processing, and an additional Cortex-M3 core for TCG Opal encryption.I guess only the server market in need of more and more bandwitdh will be interested at first.
No pcie5 in sight for amd based on this leak.

Typical PCIe 4.0 NVMe controllers only have 3 (three) ARM Cortex cores even for high-end products, with the same amount of flash memory channels (8 or 16), and they already require large heatsinks to operate reliably.
Clearly something needs to be done about LBA sector translation and garbage collection/wear levelling overhead before PCIe 5.0 x4 speeds of 16 GByte/s (and PCIe 6.0 x4 at 32 GByte/s) become viable for consumer drives.
Explicit namespace management (ZNS) does help reduce controller overhead, but it's mostly targeted at enterprise storage at the moment...
Cortex-M and Cortex-R aren't full-featured processors, but embedded microcontroller cores built for very low power consumption.by the time PCI-5 is adopted on motherboards and consumer drive reaching the 16GByte speeds come they will have moved on to newer arm processors
That would offer no additional incentives over simply using NVMe dedicated PCIe lanes on the CPU, as provided in Ryzen and Rocket Lake. You cannot cut out the CPU because the OS has to perform disk I/O; GPU cannot process cluster chains and decode LBA sectors or issue NVMe commands.wouldn't it just be easier to put an ssd directly on the graphics card ? Cut out the cpu completely in that regard
Radeon SSG software libraries were simply using the SSD RAID disk as a very fast file cache - it wasn't directly accessible from the GPU, as product ads led us to believe.Anyone here played with Radeon SSG ?
With a high performance NVMe SSD and the proper drivers, Windows 11 can soon load new games faster than ever thanks to a breakthrough technology called DirectStorage, which we also pioneered as part of the Xbox Velocity Architecture featured in the Xbox Series X and Xbox Series S.
With DirectStorage, which will only be available with Windows 11, games can quickly load assets to the graphics card without bogging down the CPU. This means you’ll get to experience incredibly detailed game worlds rendered at lightning speeds, without long load times. “DirectStorage Optimized” Windows 11 PCs are configured with the hardware and drivers needed to enable this amazing experience.
- DirectStorage requires 1 TB or greater NVMe SSD to store and run games that uses the "Standard NVM Express Controller" driver and a DirectX 12 Ultimate GPU.
darn! I only have a 256GB NVMe and making as most space as I can for my favourite games, living a life of witchery.So DirectStorage is Windows 11 only.
That's going to not sit well with some people I'm sure.
And apparently DirectStorage requires a 1TB NVMe drive...
I wonder why a 1GB drive is required though? The Series S doesn't have a 1TB drive.darn! I only have a 256GB NVMe and making as most space as I can for my favourite games, living a life of witchery.
I think that was expected, considering they are revamping the entire I/O Manager stack to support batch I/O requests.So DirectStorage is Windows 11 only.
That's going to not sit well with some people I'm sure.
1 TB requirement probably has to do with the size of typical game assets rather than performance.Do 1TB drives have a different controller which allows for something necessary that the 500GB and lower drives don't?
Yep, Windows 11 and 1 TB NVMe only.

Well, I already have an 1 TB PCIe 3.0 disk; look forward to see the benchmarks to consider an upgrade to a PCIe 4.0 model...
why 1tb mines 960gbYep, Windows 11 and 1 TB NVMe only.
