[mini] You probably thought X590 would be a thing. Nope.

GamersNexus Transcript (cleanup by OP):

AMD X590 is actually X570:
So this is something we received word on from a couple of the motherboard manufacturers when that story went live about a week ago, about an alleged AMD X590 that was in the BIOS entry and some of the motherboards out there.

 

(from) our understanding, what we were told is that X570 was originally going to be Gen-3 PCIe and X590 would have been Gen-4. And all of this is long before launch (we're talking more than 6 months ago).

So this happens all the time where stuff changes. It's just that typically the public doesn't really hear about it in any fashion.

 

so that was the plan; obviously X570 ended up being Gen-4 so X590 doesn't need to exist anymore

 

there is a separate threadripper chipset (that) we don't know the name of it yet. it may very well end up being X590, but that would be different from the one that was rumored, and it would be different because there would be an additional x4 Gen 4 lanes going up to the CPU, so you move from 4 down upstream to 8 between the CPU and the chipset and that would be the change for Threadripper. It was originally planned for X570, and then it was changed later.

 

so yeah. X590 won't exist in the form that it was rumored, but there will be a threadripper chipset, it'll be an extra 4 PCIe lanes to the CPU, and it's not going to be for the AM4 socket. just X570 for AM4

(sic) on the "4 down upstream to 8 between the CPU and the chipset" part. What steve meant was that there'd be an extra x4 PCIe lane connection on the chipset bus itself, all sharing the upstream x4 chipset interface from the CPU.

EDIT: wait hang on, I think he did mean a x8 link between the CPU and the Chipset o_o

 

yeah. hmm. THREADRIPPER WHEN, AMD???

 

... also can I say "called it", because I kinda commented that it won't be a thing in the other thread? although I kinda meant "nah it won't exist at all. might not make sense for the X570 generation" ,_,

mmmm doubt it'll get released. if two NVMe sticks require active cooling at the worst case scenario, 3 sticks.....

Well I never understood all the rumors around x590 in the first place. When x570 boards are maxing out at prices $700+, it doesn't suggest that there would be any room for x590. We'd be talking about $1000+ motherboards, that's madness and wouldn't make any sense.

Makes sense. What more is there they could do to put in a possible X590 that wasn't already in announced X570?

More lanes. They removed 4 lanes to reduce the TDP of the chipset. Enterprise gets the lanes though. Of course there is an argument to be made that it isn't worth it.

More lanes where? You're not going to get any more from the CPU, just faster ones. More lanes off chipset is of limited value as they'll all be fighting for the same bandwidth back to CPU. I did speculate could they "steal" the M.2 CPU lanes to go to chipset also, and use that as more of a hub but the benefit to that seemed very niche.

You totally missed the point. No need to go on a rant. I'm perfectly aware that it will remain x4 in but more lanes out will help people in certain scenarios. I'm not here to argue the benefits or drawbacks. You asked, I answered.

Sorry, yes I'm missing something here. I still don't get where those lanes you're talking about were.

Then you need to look up how the chipset works.

There is at least one but probably multiple $1000+ X570 boards.

If you're suggesting they took away 4 lanes off the chipset, that's all that was needed to be said.

There is plenty documentation to say the least.

might need confirmation on wording from Steve, but the current interpretation is threadripper's upcoming PCIe 4.0 chipset will have an additional 4 lanes (effectively x8) from the chipset to the CPU ._.

 

as for the now-bunk "X590" rumor, it was suggested that there were 4 more lanes within the chipset switch itself, but even if it manifests it'll be pretty hot at its busiest and (like you said) would be pretty crowded

TR has a lot more lanes to play with so it probably makes sense to double the chipset link.

 

The chipset with full lane count would jump to 15W TDP. That's a lot (versus 5W for X470). Some would probably pay for the extra lanes but they would need some serious cooling to keep that in check.
