They Put Epyc Onto AM5? Can They Do That?

I wish motherboard manufacturers took this opportunity to spend big on PCIe switches, to turn those 28 PCIe 5.0 lanes from the CPU into 56 PCIe 4.0 lanes. Yeah, PCIe switches are expensive as all heck, especially 5.0 ones, but PCIe lanes are exactly what I need in a server context

I like the look of the 7900 non-x Epyc counterpart - the 65W, 12 core one - 4464P. Pretty cheap and low power but plenty of cores for a home lab scenario.

I really like that we put more emphasize on efficiency recently, would love to see more efficient CPU hit the market. Especially for home server.

AMD is basically just competing with itself

The CPUs are only one part. We need support for them on customer motherboards. Intel shows that if you need special motherboards to run them including ECC they are extremly expensive. A Intel i5-12500 for 194€ needs a 500€ motherboard for ECC. Nuts. I hope these Epvcs will be supported on cheaper

Already got a 4244P running in the homelab. Excited so far to see how it goes!

Crazy that nobody whatsoever makes sensible PCIe slot layouts for AM5, neither on nor workstation/server.

I wish they'd give us the dual v-cache chip. It really helps in some applications.

Nice to see this. I used to buy used E3 Xeons to put in budget LGA1155 builds back in the day. Will have to keep my eyes open here in 2-3 years when these start hitting the used market.

This channel is nuts!! Good work Wendell!

You brought up something that I think is overlooked but sorely needed. A change in PCIE layout capacities on ATX and MATX motherboards. Not long ago the first PCIE was 16 lane electrical and 16 lane positions. A second PCIE was 8 lane electrical and 16 lane positions. A third PCIE and even a fourth, was single lane only or maybe 4 lane on some boards.
Today we have 16 lanes on PCIE1 and maybe a 4 lane on PCIE2 if fitted and maybe a single lane PCIE as well.
I'm with you, I would rather see PCIE 1 and 2 both being 8 lane and 16 lane positions, with additional single lane(s) as well. The supply of 16 lanes to PCIE 1 is a waste for most PC users.
Firstly they don't game or so infrequently they don't need a 16 lane GPU, secondly, not all GPUs are even 16 lanes. There are lots of PCIE plugin boards that are available and in use today that need to be plugged into the 16 lane slot even when they are 8 lanes, with some boards 4 lanes. Thus requiring the GPU to go or be relocated to a 4 lane chipset slot.
Changing the 16 lane slot to 4x4x4x4 or 8X8 or whatever does not help when the unused lanes cannot be reallocated as there are no electrical connections to be had on the board. And USB 3.2 gen2 or USB4 cannot be used as an alternative as many MBs only have USB2 or 3.2 gen1.
I don't think that motherboard makers are actually supporting the market well. Many boards are simply clones of another with a different name and "go faster" paint stripes added or removed. They are all obsessed with gaming. Yes, its big but many are casual gamers who use a pc for other purposes as well or exclusively. Many of these users have moved to big brand prebuilt basic boxes or laptops as they can no longer build a desktop PC that works for them at a reasonable price.
Also I am not surprised that Asrock came up with a beta bios, I have put them as the best support company for years and have had special beta bios private download links from them in the past in response to email enquiries.

For every "head scratching decision" AMD make they seem to have a nack for making you forget about it with a really cool decision albeit a tad late. I had forgotten about this announcement. But seen it work on an AM5...very tempting. I can see these selling like hotcakes.

I upgraded my home server last year from a dual socket Xeon v1 to a single Ryzen 7600. I ended up halving the ram, but it performs better as a game server (which is the only task that pushes it) and runs 70W less at idle.

[MikeKirkReloaded]

Part of me thinks it's not really EPYC without all the extra PCIe lanes. But... the higher clocks are nice and I begrudgingly have to admit that Gen5 doesn't need more lanes to do more work.

[jp-nypd]

I've used tons of those ASRock server. Love them.

[MonochromeWench]

Getting cheap server cpus for desktop platforms at end of life are a nice option and a bit of a small flex for late adopters and for people needing cred as serious computer users..

[jackielinde]

Did I hear AMD Ryzen 7700 (No X)? Be still my beating heart! That's the chip I have currently in my battlerig. I chose it for a balance of power, temps, and savings. It's not like I can't upgrade down the road.

[jimbo]

This brings me memories of the AMD Socket 939, with Athlon and Opteron.

[konnorj]

The only issue there is the lack of added pcie lanes which so ma y mbs screw the pooch on

1x 16x is common for obvious reasons
But having a bunch of useless 1x slots is irritating same as the constant failure to use open ended slots

Many smaller servers woudl be better served with 1x16 and 1x8 signal wise ot 1x16 with division to 8x signal for both plus a red 8x slot since so many HBAs and sfp28 etc class cards need x8 pcie or better not the x4 slots or smaller

[scooperdive]

AM5 Epyc looks very interested, i'd be interested to see how this progresses and if they keep going with it.
