The B650E Aorus Stealth Ice is Gigabyte's First Motherboard for AMD CPUs with its Connectors on the Back

Gigabyte's new Stealth series of motherboards has to date only had a single product, the Z690 Aorus Elite Stealth, but now, Gigabyte has added its first Stealth board for AMD CPUs. The B650E Aorus Stealth Ice not only has all of its connectors on the back of the board, but it also has a white/silver PCB with a similarly coloured front and back cover. Apart from the DIMM slots, all connectors are also in somewhat matching colours, although judging by the pictures, the colours don't quite match on all the connectors and slots. That aside, the B650E Aorus Stealth Ice is a pretty competent board, as long as you're not interested in adding anything more than a graphics card and some NVMe SSDs, as it has zero additional PCIe expansion slots. It's a rather bold move by Gigabyte, but at the same time, most gamers and consumers don't tend to add PCIe devices to their computers outside of additional storage these days.

Besides the PCIe 5.0 x16 slot, you get two M.2 sockets wired to the CPU, one PCIe 5.0—with its own, larger heatsink—and one PCIe 4.0, as well as a third PCIe 4.0 M.2 socket via the chipset. There's also support for four SATA 6 Gbps drives if more storage is needed. Gigabyte has also added an internal HDMI 1.4 port that's limited to 1080p30, which is intended to be used with Gigabyte's LCD Edge View display. Other connectivity on the back of the PCB includes a USB 3.2 Gen 2x2 (20 Gbps) port, a USB 3.2 (5 Gbps) pin-header as well as the usual USB 2.0, fan headers and LED headers that you'd expect from a modern motherboard. The VRM design is a 12+2+2 design with a 60 Amp DrMOS configuration for the 12+2 phases for the CPU and GPU.
Around the rear of the board you'll find a single HDMI 2.1 port which is limited to 4K 60 Hz, a USB Type-C port that delivers 10 Gbps of data in most instances—but will support USB4 with the right APU in the CPU socket—that also offers PD Alt Mode support for up to 4K 144 Hz. There's also a 2.5 Gbps Ethernet port, Gigabyte's newWiFi EZ-Plug for the WiFi antenna, which is connected to a MediaTek MT7925 WiFi 7 / Bluetooth 5.4 module, which sadly is limited to 160 MHz channel width. Finally there are two 10 Gbps USB Type-A ports, five 5 Gbps USB-Type A ports and four USB 2.0 ports, three audio jacks connected to the old ALC897 audio chip and a Q-Flash Plus button. Overall it looks like a pretty competent B650E board, but with the 800-series chipset just around the corner, it might have been wiser to release this as a B850 board, at least to win over consumers that don't know that the two are the same chipset. Gigabyte provides a list of compatible chassis here.

I wonder how hard these connectors are to get a hold of with your hand to unplug on the backside. You've got all the metal of the back panel to fight along with the recession created by mobo standoffs all through a routing slot I imagine.
Just seems like a huge pain to build with.

Xuperfor that , You need a custom case.
Custom?

Hardly, there are several cases on the market today compatible with these kinds of boards and more are coming

Easiest builds I have ever done.

Ive been advocating this to be the new standard for a reason.
AssimilatorOn further consideration I think this is actually pretty dumb. Gigabyte hasn't tried to do anything clever with the onboard connectors, they've literally just flipped them. But what they have here is a real opportunity to mimimise electrical trace lengthy and save a fuckton of money - which they haven't taken! This is better explained with a picture so here's some Paint work:



Now the power connectors are near the parts of the board that need the most power (I don't know precisely where those are so I put the 24-pin between the CPU and PCIe slots; sue me).
Now the chipset connectors are (mostly) on the opposite side of the chipset.

Instead of cutting half-a-dozen extra, irregularly-shaped holes in a chassis motherboard tray, you only need 2 or 3 larger ones (so chassis machining is cheaper and faster). And of course cables don't need to be as long, nor is routing them so much of a pain. But most importantly, trace lengths are far shorter, which also means you don't need traces that are as thick, so as a board manufacturer you basically just win. You can then put the money saved from that into even more unnecessary "thermal armour" on the bottom surface!
Holy brain rot

I need to see it person. Not that I've tried to search for it but I still haven't seen a picture with the side panel off showing all the connections in a completed build and the clearances, it's always the windowed side.

ChomiqMy X570 board from 2018 didn't have it, why should a board from 2024 have them? What's next, where's the serial port?

That M2 heatsink will cause some clearance issues. And yeah, it's an ATX board with a single PCI-E slot.
I'm sorry you got left out of the P/S2 port on your board. My x570 board that came out towards the end of 2019 has one. Also, my comment was tongue in cheek and in no way meant to be taken seriously.

You're not looking hard enough. MSi has a full build video. Starting at 2:31 they show the connections. Its easy as can be

This works just fine with Ryzen 9000 CPUs and it's identical to the B850 chipset in terms of features.
You've clearly missed the fact that the 800-series AMD chipsets are the same as the 600-series by large, with the addition of USB4 on the higher-end SKUs.

Admittedly the X870E would offer more connectivity, if that's what you're after, but this board clearly isn't it then.
I would like that to be the case, but I hear 800 series might have improved memory overclocking capabilities. Not sure how, with 9000 CPU's having the same IOD. I guess they're going to do some improvements when it comes to memory traces etc but let's see. I actually want that to not be the case so I can just re-use my x670e for 9950x

There are only two types of memory layouts, T-topology or daisy chain and until we move to something like CAMM2, this isn't going to change.
As such, there's only so much the board makers can do on their side and as you point out, the memory controller is inside the CPU package and the IOD is said to remain largely unchanged for the 9000-series.
Personally, I wouldn't waste the money on a new motherboard, unless USB4 is a must have feature.

Memory sweet spot has been bumped up to 6400 for 9000 CPUs

Yeah I hear that too but i'm wondering how, considering the IOD is the same as 7xxx.

I am aware of the topologies, but mobo makers can still add layers to the board and clean up power delivery etc for minimal gains. Not sure if any of that is going to happen with 8xx motherboards, I guess we'll have to wait and see where the supposed added memory speed is coming from, if at all.

I mean theres a lot you can do to squeeze higher freq out of a design on the physical implementation side. It can be the same overall design from a gates, RTL stand point but what the layout engineers do can yield better performance.

Im not an engineer at AMD, but i do do layout at another company on DDR controllers. If they designed the controller for a target sweet spot of 6400 without changing any gates/rtl, they did layout (especially cts), timing closure and clk/data skew alignment at that target frequency which is totally possible. 400mhz isnt that big of a bump.

Honestly, we're already at a point where not much more can be done with current motherboard layouts and memory.
If you want really high memory speeds with DDR5, memory modules a CKD is most likely going to be the way to go anyhow and then latencies will go up.
I honestly believe there will be minimal benefits to be had from throwing away your motherboard.

I agree, and hope it is the case on the CPU side as opposed to the motherboard. I just want a nice 8000 mhz 2:1 on a 9950x while re-using the x670e.

Rumor was that the next generation of boards would feature better trace design to improve signal integrity. I can’t remember the exact quote/terminology, something to do with “back drilling”. If you’ve read about or had the chance to experience 2:1 memory overclocking on B650/X670, for any board that isn’t the Gene or Tachyon (only 2 dimm boards released, one purchasable and the other vaporware), boot to boot instability is nearly impossible solve. I don’t know if it’s been proven yet but many believe it had to do with mismatched tphydrl timings between dimms/signal integrity at higher frequencies.

When testing on my b650 strix e, 8000 would run for 8+ hours in kahru without errors, then last 10 seconds the next boot.

If I were buying an AM5 build I would absolutely wait for more leaks on X870E before deciding between 600 and 800 gen boards.

*6200-6400 is also attainable on Zen4, which gives me hope they’re sandbagging the real sweet-spot for enthusiasts. It’s entirely possible 6600-6800 could be viable in 1:1.

The Tachyon wasn't vapour ware, it was simply released in an extremely limited run due to piss poor management and sales people at Gigabyte. Sales didn't know how to sell the board, which lead to management not launching the board outside of Japan and a few limited units in the US.

It effectively was. The board was never available in the US afaik. I checked every week since news articles first revealed the Tachyon and e-mailed CS at Gigabyte several times, and not once did they provide any information about the board actually being available for purchase.

Unless you have proof otherwise. Also, what’s the point of singling that out, that was the least relevant part of the entire post.

I mean, I know HiCookie who helps design and test the Tachyon boards and I know other people at Gigabyte, so yes, I know it was sold, but it was only a few hundred units ever made.
I'm sorry you were unable to get one, but as I said, piss poor management is who you want to blame, not some poor customer service people.
A lot of people at Gigabyte were disappointed that the board wasn't more widely available as well.

Indeed. There were leaks of future 800 series board names from Gigabyte and a new Tachyon was listed there. Unfortunately only in white color like the board in this article (ICE moniker).

Knowing someone doesn’t mean anything. Where were these alleged boards listed for sale. Newegg? Amazon? Microcenter? B&H? Any e-tailer?

The only two people ive spoken with that own or I’ve seen with the board are wdm (on OCN who tests boards for gigabyte) or Buildzoid, both who have mentioned the board was not available for purchase and was sent to them by Gigabyte.

I don’t blame CS for anything, it’s not their fault, they simply never had that information to give; which more than likely means the board was never listed for sale in the US.

Ok, then... Be like that.

You don't make retail products as a company if you're not going to sell the product. I don't work for Gigabyte, so I don't know which retail they sold them through, but as I said, it was a really limited run of a few hundred boards, most went to Japan.

The reason you weren't told, was due to how bad their sales people are. Due to them being unable to figure out how to sell these boards into the channel, there was a as I've mentioned, a very small amount of boards made. However, it was sold in retail at one point.

Be like what? We know they were made as they handed out boards to XOC enthusiasts. There is zero proof of a listing in the US though. If you “know people”, why not find out where the limited run was posted on an e-tailer for the US then? I’ll wait. You’d think after diligently researching the board and checking multiple sources and sites since news leaks would’ve eventually lead me to a place of purchase, if they were in fact ever listed.

TheLostSwede@mkppo see the sticker?

Yeah I mean, we all know the 6xx supports upcoming 9xxx CPU's there's no argument to be had there. Discussion was whether 8xx motherboards will actually allow higher memory speeds, something that i'm doubtful about but let's wait till release I suppose. As Rv8000 mentioned, getting 8000 to work on x670e is an absolute PITA, but it's very close. Like 7600 is easily doable, but that extra 400mhz boosts performance considerably because the IF comes up to the standard 2000mhz. So if by any chance the 8xx motherboards do overclock better on the motherboard front or there are actually decent 2 dimm options outside of the impossible to find tachyon and ugly looking gene, i'll just get one. X870 Tachyon ICE looks great, let's hope it's actually available this time around.
