Question 'Ampere'/Next-gen gaming uarch speculation thread

[Ottonomous]

How much is the Samsung 7nm EUV process expected to provide in terms of gains?
How will the RTX components be scaled/developed?
Any major architectural enhancements expected?
Will VRAM be bumped to 16/12/12 for the top three?
Will there be further fragmentation in the lineup? (Keeping turing at cheaper prices, while offering 'beefed up RTX' options at the top?)
Will the top card be capable of >4K60, at least 90?
Would Nvidia ever consider an HBM implementation in the gaming lineup?
Will Nvidia introduce new proprietary technologies again?

Sorry if imprudent/uncalled for, just interested in the forum member's thoughts.

I missed the heatsink behind the card on that image. I took it for a mirrored front side since it has a GPU sitting there. And the pads for the vregs and power connectors and such are there.

This image very clearly has no memory on the backside, so maybe we are seeing two different PCBs?

EDIT: Looking again, I am quite sure those first two images are of the front side, the heatsink is there behind it, but not attached. The inner screws attach to the backplate.

I think this pic was included as a reference to the current NVIDIA RTX 2080 Ti. There are no solder points for memory toward the I/O bracket, like the current 2080 Ti.

Wow, 384bit 21Gbps would be what, over 60% more than the 2080 ti? Is the 3090's memory bandwidth overkill, or is it really going to be that strong of a card?

No 2080Ti's have three 8pin connectors on them that I know of? Maybe some super high end OC model?

But even then, those first two images clearly show the GPU chip, that wont be visible on the back.

Overkill? maybe. But at least GDDR6X helps turn back the race of core speed vs memory speed a bit.

If calculating the ratio of FLOPS (at rated boost frequency) to bandwidth:
GeForce GTX 780 Ti: 0.063
1080 Ti: 0.042
2080 Ti: 0.046
3090 (1.7 GHz): 0.056

12GB in a high-end part is piss-poor given we've had 11GB in consumer space for over 3 years. Especially considering this thing will almost certainly be horrifically overpriced.

Can't have people to "AI" on cheapo GeForce hardware. You need to shell out even more for that to get you that needed memory. That certainly plays a role plus the fact 12Gb is more than enough for gaming right now and they already seem to have issues with power use.

The Lightning Z does (spec TDP is 350 W)

There is another image, a close-up without mosaic. It's covered with an Intel CPU. i'm still on the position this pic is part of the back side.

Does seem like the FE has a fan on both sides.

GDDR6X does exist didn't expect that

Neither did I.

I'm pretty sure that it shows two different cards. The first one has Intel cpu there for some reason. Also check the pcie connector positions.

This is probably going to be Fermi 2.0 (at least heat and power use wise).

This is a wild guess but wasn't there speculation of Nvidia using an off-die traversal co-processor to accelerate RT performance? I wonder if the leaker intentionally hid the backside of the GPU because that's where such a co-processor, if it exists, would go, and perhaps the 3x8 pin power isn't necessarily because the GPU is power hungry but because it needs to also feed power to a separate die.

You know it's the back side just by looking at the the position of the PCIe edge connector even outside of any other parts. The only way that could be the "front" of the PCB is if nvidia flipped it around and mounted the die on the opposite side of every other GPU.

An aside, I love how they add the Intel CPU to cover things, and then blur out the CPU details, for extra obfuscation.

nVidia didn't take the images. Its also semi common for images to get mirrored on cell phones, or to make them not match image searches.

Also, Micron lists the card as having 12GB of ram, and each chip as 8Gb (1GB). Which would make it odd to have the memory on the backside of the board. Unless this was maybe done for cooling, to keep the RAM away from the GPU and VRMs.

I'm wondering if these will go on sale before reviews are out like last time...

Sounds about right for the stock TDP. The 2080 Ti's official boost is 1545, but from AT's review most games were in the 1700-1800 range. Maybe it'll be the same way, so in actual games it'd be closer to 1900 with stock TDP and 2000-2100 with the FE.

The TDP for RTX 3080 is rumored to be around 300 to 320W. If that is at stock speeds, you better get yourself a water cooling solutions.

And another pait of high-speed fans to feed enough airflow to your cases...

I would love to see an AIO like Fury X/Vega 64 LC on the top end part. But doesn't look like thats in the cards from the leaked cooler images.

You can even see the through hole connectors for the IO ports on the right side of the board that I've circled here. Even if the image was flipped, there would be IO along the edge of the board. This is the back side of the PCB.

The FE is usually what OEMs take. Have to figure they would greatly prefer air.

Alleged 3090 PCB pictures showing 3x8-pin: https://www.techpowerup.com/270986/nvidia-geforce-rtx-3090-ampere-alleged-pcb-picture-surfaces

That configuration allows a theoretical maximum of 525 watts.

That's a custom cooled card from the Colorful Vulkan series, which also used 3x8 pin connectors for the 2080Ti.

In the past when the reference FE was
always blowers yes but not anymore. Look at the latest alienwares. Blowers with green pcb not FE dual fan

Ahh, good catch. Definitely the back side then.
