AMD Readies Three HEDT Chipsets: TRX40, TRX80, and WRX80

AMD is preparing to surprise Intel with its 3rd generation Ryzen Threadripper processors derived from the "Rome" MCM (codenamed "Castle Peak" for the client-platform), that features up to 64 CPU cores, a monolithic 8-channel DDR4 memory interface, and 128 PCIe gen 4.0 lanes. For the HEDT platform, AMD could reconfigure the I/O controller die for two distinct sub-platforms within HEDT - one targeting gamers/enthusiasts, and another targeting the demographic that buys Xeon W processors, including the W-3175X. The gamer/enthusiast-targeted processor line could feature a monolithic 4-channel DDR4 memory interface, and 64 PCI-Express gen 4.0 lanes from the processor socket, and additional lanes from the chipset; while the workstation-targeted processor line could essentially be EPYCs, with a wider memory bus width and more platform PCIe lanes; while retaining drop-in backwards-compatibility with AMD X399 (at the cost of physically narrower memory and PCIe I/O).

To support this diverse line of processors, AMD is coming up with not one, but three new chipsets: TRX40, TRX80, and WRX80. The TRX40 could have a lighter I/O feature-set (similar to the X570), and probably 4-channel memory on the motherboards. The TRX80 and WRX80 could leverage the full I/O of the "Rome" MCM, with 8-channel memory and more than 64 PCIe lanes. We're not sure what differentiates the TRX80 and WRX80, but we believe motherboards based on the latter will resemble proper workstation boards in form-factors such as SSI, and be made by enterprise motherboard manufacturers such as TYAN. The chipsets made their way to the USB-IF for certification, and were sniffed out by momomo_us. ASUS is ready with its first motherboards based on the TRX40, the Prime TRX40-Pro, and the ROG Strix TRX40-E Gaming.

That is likely, also the TR2 chips - 2970wx & 2990wx - had 2 CCX to go through a couple of hops IIRC to access memory, they couldn't do it directly. This shouldn't be the case with TR2 & the IO die, not to mention memory support & IF have been enhanced. I'd say up to 32 cores should do just about fine for most tasks, & for higher core counts there'd likely be 8 mem channels.
That is also my thought process that they will be able to have the 2990WX replacement wired just like the 2950X in terms of the memory but the 64 Core will probably be just like the current 2990WX in terms of how it is configured. I am also wondering if the 32 core will be good for gaming if tied directly to the memeory controller for all CCX units..

Id like a tweakers WRX80 dual cpu board, akin to skt 1207

Better yet tr and epyc on same exact platform
Lets wait and see fact is the WRX80 will not be cheap at all, as all heavy workstation boards are kinda high prices.
But lets be honest i am pretty sure those will be like the xeon boards the best you can get.
However those who game should not even look at these boards at all, they are build to last and often use ECC memory which games really do not like.
The question is will the TRX80 chipset be able to run faster memory or will it again be limited for safety as usual.
Ofcourse i have to add that even though 5000 mhz memory is available its not going to make a great jump in performance like everyone is expecting. I certainly use 3000+ memory but overall the gain is not so high.
The only thing which is not going fast enough for me is drive speed, even though i like nvme its not as fast as for instance the intel pci ssd cards. They excel in synthetic benchmarks but at normal tasks second hand enterprise ssd beat the nvme at its own game. I use many used enterprise ssd because companies constant replace them to prevent data loss might happen. But i promise you those second hand drives can last very long in you pc.
Most of these drives have a super high number of write cycles, let me be straight here they can die ofcourse.
But i use them since intel released the first ssd's those are what about 15 years old or something near.
But they still run perfect " with zero failures up to now" in my nas a read/write cache and i used them alot in raid 0 with 4 or 8 of them to store my games and heavy programs on them and the loaded every virtual machines from and on them ( constant updated also ) so the read and writes are so high i will not even try to copy them over for you to see. And they still running like nothing has been written on them since the first day.
Ofcourse i admit i constant take care of them and keep a good bit free but this far non of them has more than 20 cells locked as unusable yet .... 15 year heavy usage try that with a hard drive.
Anyway lets wait and see how they are going to implement these in reality, but i really consider switching to the trx80 because that would alow me to run much more and hopefully very fast ram memory.
But i admit to wait till people have used them, because i really know how nasty latency can work out.

Why would gamers need 4 channel memory and even more cores? (that's what TR is about, right?)
They don't this for workstations, think cad, 3d editing,movie production, math.
