lifeforce Hi Everone,

I just wanted to throw this bit of info out there.
it may have been mentioned but I didn't read all the comments yet.

when developing any new products the manufacturers will always test different ways to use the product to verify it will work in almost all conditions.
(this is how the QVL is created)

so if intel is testing their SSD using AMD CPUs, then they are verifying it will work with that hardware.
with that said I would not be surprised if intel was also testing their SSD using other processors too. (for instance: snapdragon processors, apple processors, etc)

if intel only verified that their SSD worked only with intel systems then they will be losing potential buyers.

You realize your statement is contradicting itself? why would they be developing pcie4th gen SSDs if they are skipping to 5th gen? Also, I dont have time to search it up(maybe someone else can) Intel may have released pcie 3.0 to the consumer first, but IRC AMD was first to make pcie 3.0 gpus. I am sure somewhere at one time or another a person might have posted such responses. However if your looking at actual tech sites, they did do testing on pcie speeds and gpus. again IRC single gpus were not exceeding or capping pcie bandwidth speeds at the times of testing with then current hardware. i'm sure there are tons of these articles out there.

Countering your "Intel were also the first to PCIE 3.0 and AMD owners were all about "yeah but our GPU isn't bottlenecked in 2.0". with https://www.legitreviews.com/intel-s...-gamers_212350

I want to see the crow eating begin when intel releases PCIE 4th gen motherboards. it's coming...
I love the "Expert pin-bender" thing! :thumbsup:

That and everyone is bottlenecked by every non-optane NVMe SSD. 4K Randoms suck even inside cache, which 4.0 can help with by enabling the use of faster cache.
Yeah, so you're limited by the number of lanes base on the platform you are on....

Will admit that 4k random reads suck, but that's also not really a limit of PCIe 3.0

Just saying....

Looks like the memorylatency in Ryzen cpu's is too high...

I want High 4k rr @QD=1 over sequential speeds any day, but HEY! I want both in the same time
I also get about 300MB/s 4k random on a 900p, but I also get 235MB/s when I run it over the pcie gen2 z97 chipset

Intel were the first to start using DDR4 while AMD waited for AM4, and AMD owners were all about "yeah it doesn't matter".

Intel were also the first to M.2 if I remember right.

So it doesn't really matter. AMD might be the first to jump the gun, but it isn't going to change when and how we will use it. That will most likely wait until nvidia and intel will also join in. It might push the others to use it faster, but from what I have seen, it could be that intel will skip and go right into PCIE 5.0 (which specs are already final and released early last year, so it will make more sense).
Intel's first generation of DDR4 chips also supported DDR3L as they knew the cut over would take time.

AMD also had 25.6GB/s of bandwidth available via HT to their 40-lane PCI-e 2.0 NB and 6xSATA3 SB, while Intel's consumer boards supported 8GB/s (PCI-e 2.0 x16) and 2x SATA3, 4x SATA2.

NVMe on M.2 2280? Yes. M.2 is an old and very confusing socket though, being used for everything from laptop WiFi/WAN, to mSATA solutions.

Honestly, who on here has been bottle necked by their NVME PCIe 3.0 4x drives?!

In defense of Intel, their iGPU was likely using PCI-e 3.0 before AMD came out with a PCI-e 3.0 dGPU.

Yes, because global supply is going down while global demand is going up.

No idea but it makes me smile. Doesn't have to be bunnies either, feel free to choose a better word.
