Linus apologizes to Epic boss for comments on PlayStation 5 SSD


Linus of Linus Tech Tips called Tim Sweeney a little while ago and criticized the Epic boss’s comments about the PS5 SSD. Now Linus has apologized and deepens the storage technology of the PlayStation 5.

Tim Sweeney is a big fan of the PS5 SSD, and went so far as to call it “divine”. Sony’s next generation SSD is beyond the highest level PC SSDs on the market today with the best storage in its class, said Sweeney. Like many PC gamers, Linus Sebastian was skeptical and commented on Sweeney’s shilling for the PS5. But now, after watching Mark Cerny’s presentation, delving into research and checking Sony’s old SSD patents, Linus apologizes.

Apology video goes into detail on PS5 SSD, but none of the details will surprise anyone who reads our deep dive coverage on PlayStation 5 SSD.

“The bottom line is, Mr. Sweeney probably knows that we don’t know. But even based on what we can see for ourselves, if what Sony says is true, it is not shilling for the PS5, “ Said Linus.

“I put some of you on the wrong track, it was a breach of our trust, and I can do better. And finally, once again, I am particularly sorry for Mr. Sweeney who may not make fun of my blunder, or my apologies, and I would understand that. ”

Most of the potential of the PS5 SSD isn’t just the 5.5 GB / s raw speeds of the PCIe 4.0 NVMe M.2 SSD, but how the console will actually make use of of these speeds.

The PS5 has a special 12-channel memory controller that allows instant access to data and streaming to a dedicated I / O block built into the SoC, which is then loaded into the GDDR6 RAM pool of 16 Go and transmitted to the processor and the GPU for Processing. Custom operating system software and tools allow Sony to bypass the limitations of environments like Windows 10 – instead of being designed for a myriad of versions, the PS5’s operating system is designed specifically to synergize with the hardware itself.

Along with a decompression block that uses Kraken’s new compression technology, the PS5 can extract resources compressed at 9 GB / s with speeds up to 20 GB / s, and decompress them quickly for use in the system .

What does that mean? The following is a brief breakdown of what to expect from the PS5 SSD, but keep in mind that this is just the start. We don’t really know how far developers can push this technology.

The decompressed elements load much faster, allowing you to play instantly without loading time.

Since SSDs don’t need to search for data like a hard drive, eliminating search times will also supercharge loading and streamline games – environments will be accessible immediately, no texture will appear like in No Man’s Sky on PS4, and the system will be able to access and load the data in the blink of an eye. Compressed assets can also be prepared faster than ever.

Sony says PS5 SSD is 100 times faster than PS4 and will result in open world instant play.

Games can be made smaller now that there is no need for duplicate assets.

Currently, games have to store assets in the RAM buffer, which requires a lot of data replication. Games like Spider-Man, for example, have many separate instances of small items like light poles, newspapers, cars, and fire hydrants. With the PS5’s SSD, the game can simply load a single asset as needed instead of having to load hundreds from the RAM pool (the PS5’s memory buffer can also process speeds of up to at 448 GB / s).

Streamlined data will make everything more efficient, including graphic effects.

Now that the PS5 can broadcast data, textures and assets via RAM and to the CPU and GPU for processing at such high speeds, it allows an even more efficient delivery pipeline for this data. This is vital for new and improved graphics upgrades like raytracing, which rely on complex lighting rendering techniques made possible by the data powering the Navi RDNA 2.0 GPU.

It will also allow new Lumen features found in Unreal Engine 5, a new type of photogrammetry lighting system that allows developers to create next-generation global lighting in environments.

This pipeline will also enable the new Nanite system in UE5, a micro-polygon rendering technique that allows developers to render cinematic-quality images in real time with sub-pixel control. Streamlined data pipelines are needed to facilitate this type of high-end technology.

The SSD will also be extremely useful for other features such as 8K visuals, native 4K 60FPS, 1080p 120FPS, etc.

Sony’s PlayStation 5 is expected to be released in 2020. No exact pricing or launch has been announced, but Sony will soon release the PS5’s launch exclusives.
