[Guru3D] Rumor: NVIDIA Ampere GeForce RTX 3070 and RTX 3080 specs surface

Quote:
Of course, you'll need to take a ton of disclaimers in mind, and huge grains of salt perhaps even the size of golfballs when you read this one. But history has proven over and over again, that there often is validity (at least to some degree) to be found in these leaks. So here we go.

On both Asia based mydrivers and on a twitter account from ‘KittyCorgi’ info has appeared on two new NVIDIA GPUs, allegedly Ampere microarchitecture based. Two GPU models are named, GA103 GPU (RTX 3080) which would get 60 SMs (Streaming Multiprocessors aka shader core clusters) and then there is a mention of GA104 with 48 of them (RTX 3070). The GPU IDs seem to be reversed for whatever reason, we know, again rumors. If you multiply the clusters with 64-shader procs per cluster (which is what NVIDIA historically has been doing) each then you'd see 3840 Shader processors and 3072 shaders processors respectively. The leak mentions a 320-bit bus for RTX 3080, which could mean a 10GB memory GDDR6 configuration.

According to recent claims the chips are fabbed at Samsung, which sounds expensive over TSMC. Samsung's 7-nanometer process would use EUV, making the chips easier to fab. Historically TSMC always has been NVIDIA's biggest partner. TSMC has been fighting on many nodes to keep up with demand though. So then, 7nm EUV fabbed NVIDIA Ampere GPUs.

Definitely curious to see the performance and pricing. Wonder if Nvidia will rebound much from the 2000 series or keep pissing off the market with insane prices for marginal gains.

There's already a rumor thread discussing Ampere. This should also be in rumors.

seems weird doesn't it? such a low core count on this process? what happened to smaller cores are less powerful, but that's made up for in quantity?

R.I.P. Zawarudo, may you OC angels' wings in heaven.
If something appears too good to be true, it probably is.
Best R0ach Quote of all time : TLDR: Haswell might be the last legit gaming platform unless mice get their own non-USB interface on some newer architecture.

But not part of the OP right? There no rule against posting news that was discussed, and I've not read every single post on the other thread.

Not a lot of people posting news at all these days so just trying to keep things fresh.

I appreciate it. I often don't keep going back to a news thread I already read. So if new info is only being placed there it goes missed.

It's probably best not to talk about price rumors -- otherwise everyone will get depressed and/or angry.

For sure it has time and time again to prove pointless as we're always way off. Hopefully this time its a shock in a positive direction.

But recent events (Intel HEDT line) that competition can change anything.

The 50% rumor is plausible in regards to RT performance. If Nvidia can double the RT core count, raytray would be somewhat more swallowable, even if $ stay stagnant. Also 2nd quarter?
