Log Best 5080/5090 design for SFF - FE? AIB?

[boundary-stone]

The 5080/5090 Founders Edition cards have identical length / width to the 4090/4080 FE and are much thinner thanks to a kind of incredible thickness of only 2 slots.

The biggest concern with the 5080/5090 FE design though is that they use a new dual flow through fan design (vs the 4080/4090's 1 flow through fan & 1 rear exhaust fan) that could make it particularly unsuitable for many SFF case layouts - especially sandwich layout cases - since the 5080/5090 FE cards will be dumping 100% of their heat directly into the case.

Has any manufacturer announced a 5080/5090 design that looks like it might be a better fit for SFF than the 5080/5090 FE?

This MSI Inspire card looks interesting as a more compact AIB card design with 1 flow through fan (vs 2 on FE), but it doesn't offer rear exhaust (most AIB models don't) and it's both longer / wider than FE and thicker than the FE at 2.5 slots.

Inno3d has a dual slot, 304mm 5080. Asus Prime is 50mm and 306mm.

Just saw the Asus Prime 5080 - 306 x 126 x 50 mm is nice. The width is actually 11mm lower than the FE cards (137) which could make it a lot easier to fit the 12VHPWR connector into less wide traditional layout ITX cases (or shorter sandwich layout cases) than even the FE cards. No Asus Prime 5090 model.

The Inno3d 5080 looks like a nice card for those who can buy it (300x120x50), but the Inno3d 5090 is much much larger (333x137x50).

Check out the power connector on the FE, it's angled now so the cable can lay on the card which won't require as much space.

RTX 50 FE cards with the double fan passthrough is pretty SFF incompatible, at least for the SFF case with riser cables.

Oddly enough, short riser like Node 202 or S4 Mini would take full advantage of the double fan passthrough, especially as the power connector of the FE are now again angled (like RTX 30 FE).

Afterwards, I'm interested to get some thermal/noise results from the RTX50 FE cards, especially on RTX 5090 vs the 3.5/4 slots AIB models

Strangely I'm not in a hurry to upgrade to an RTX 5080 as my RTX 4080 FE is fulfilling my current needs easily..

Yeah, something like the Fractal Ridge in theory would be perfect, but larger than the FormD T1 and no AIO support. Are there any similar cases with separate GPU compartments that still allow for at least 240 AIO support?

Or something like the Louqe Ghost R1 where you can put a D15 G2 on the CPU with dual 140mm fans capable of eating / exhausting all that flow through GPU heat while still keeping the CPU cool enough.

The TDP increase 4080 -> 5080 is a manageable 35 watts - 325 to 360. The TDP increased 4090 -> 5090 though is 125 watts (!) - 450 to 575. A lot of builds that can move enough air to handle 4090 heat won't be up to the 5090's full on furnace. The 360w 5080 should be fine with 2 slot cooling, but it's seriously hard to imagine how the FE cards are going to cool 575 watts with 2 slot cooling.

This looks like an excellent fit for all sandwich cases, but of course it remains to be seen how loud the 5080 is which such a "compact" cooler...

Wow - that Inno3D 5080 is only 300x116x41. It looks like it has a vapor chamber too, which is unusual for a compact card and may help with noise.

Most of the compact 80/90 class cards in the past have been MSRP type models that haven't used vapor chambers making them noisier than they needed to be.

I've a second look at the Fractal Ridge...well not for me.. It is a bigger, better Node 202...but not worth for RTX50 FE.

Regarding TDP of the RTX5090, it is very urgent to wait for independant review. The RTX4090 FE was easily pushed to 600W as power consumption...thus RTX5090 TDP is just a different reference point..let's see.

Agreed on waiting for reviews for actual 5090 power consumption. The 4090 is rated for 450 watts and in practice, especially with DLSS, it often only pulls around 300 watts. If the 5090 behaves similarly while being rated at 575 watts it could land closer to 350 watts in typical usage so I wouldn't be surprised if the gap in real world use from 4090 to 5090 was closer to 30-50 watts (350 vs 300) than 125 watts (575 vs 450).

It looks Gigabyte has 1 SFF rated 5080 design (with 3 barely different skus - Windforce, Windforce OC, Aero OC).

Essentially the Gigabyte 5080 MSRP card (Windforce) is 304 x 126 x 50 and has a proper vapor chamber cooler. This may be the 5080 to get if you can't get the even more compact Inno3d model (300x116x41) or if the Inno3d model being so aggressively compact makes it impractically loud.

FWIW looking at the Inno3d design again it appears to have like 1.5x flow through with a much larger flow through window than most 3x fan cards. It also appears to lack a vapor chamber and have more limited memory cooling capability though (aluminum vs shared copper vapor chamber on Windforce).

EDIT: MSI 5080 Ventus is 303 x 121 x 49 - so similar dimension to Windforce, but like the Inno3d 5080 also misses out on the Windforce's vapor chamber.

Personally I'd be most interested in an Asus x Noctua 5080 / 5090 that you could setup for top intake (or top exhaust) in an inverted case. Or an easily deshroudable card with a heatsink a consistent 140+ mm wide that could be lined up well with a pair of top mounted (if inverted layout) or bottom mounted (if traditional layout) A14x25 G2's. Or even a longer easily deshroudable card that could play well with a trio of T30's. I feel like the 5080/5090 FE could actual be good candidates for deshroud with their double flow through design - should be easy enough to remove the stock fans and lineup 2x T30's with the stock fan locations.

I'm currently running a deshrouded 4090 Suprim in an inverted NCASE M2 with 2x A12x25 for intake (T30's are too thick to fit) and it's a really solid setup.

Well I've double checked all "SFF" RTX 5080 GPU from Asus Prime, MSI Ventus/Inspire, Gigabyte Windforce.

For my point of view, they are all sharing a major issue for SFF : exhaust air direction : Mostly top & bottom & 1 passthrough. (nothing at the rear..ie i/o side, like RTX 4080/90 FE cards)
My main concern is that design, all hot air will be put inside the SFF case...if there is no active cooling on the case to exhaust hot air, there is a major chance to recycle GPU hot air.

I must say that I'm pretty interested in the RTX 5080 FE now, even inside the U-ITX or any my SFF case..

Some new benchmarks are being released on the new RTX 5090 / 5080.

My main concern is that the RTX 5080 raster performance uplift versus RTX 4080...approx +20% only. All frame generations techniques are useless if the the base framerate is too low. And MFG vs FG...well I don't really care...if I'm at 140fps or 230fps...as it is not leading to better input lag or any other game changer.

In my current mind, it is either I stick to my RTX 4080 FE or I switch to the RTX 5090 FE for better raw performance...only if the FE 2 slots cooler is effective in terms of cooling/noise..

Let's see...

What is your resolution and refresh rate? My cube neighbor at work is still rocking 1080p, I'm rocking 4K.

Hopefully that 16GB frame buffer ages better than the Ampere 8GB framebuffer on the 3070Ti and lower cards.

I've a Samsung neo G9 : 5120x1440 up to 240hz refresh rate, thus pretty similar requirements as UHD (3840x2160) monitors @240hz.

Hmmm you have a point there.. this sounds like the cards are better optimized for console cases.

Who knows, maybe Nvidia is trying to win some contracts to power next gen consoles?

Shoot I probably could have stayed in my Ncase m1 just fine with these double flow through cards. Damn it

Jayz2Cents did a PC build with an FE5090 ...catch being there's no details about performance or footage of the system beyond building montage and POSTing.

Sidenote...I find it funny that this time around Nvidia is clearly playing nice with influencers on these cards to hype them up a bit and let early access to people who have been critical of Nvidia in the passed.
