I think you misunderstood my post. It's not about Nvidia or AMD stock (though AMD is sure to better than Nvidia on launch as it can't get any worse than that), it's about buying a card (in this case the 10GB 3080) that may soon be superceded by a better one with more VRAM as a knee-jerk response to Big Navi. I don't buy a card I don't feel is the best choice just because 'it's in stock'.

You're predicting a card that hasn't been announced and stock levels you can't possibly know exist until we see how the launch goes.

To be honest, I regret quoting your post and getting involved so happy to leave it at that.

It's clear that Nvidia have to respond to Big Navi with something to retain the performance crown, that is crucial for them and that's why we are seeing a splurge of new rumours on the usual sites. I will aim to be buying a 6800XT because from what we have seen so far and the benchmarks that have been released it looks like a better deal in terms of value and spec than the 3080. No way would I be silly enough to pay money immediately for something like a GPU and then willingly wait months to get what I paid for... to me that's a mugs game.

What rumours? GA102 is 99% fully enabled, while GA100 is not suitable for gaming.
RTX 3080 Ti won't be faster than RTX 3090, they have space for RTX 3095 or RTX 3100 but it would take at least 6 months if it wants to respin it using the processes of another foundry.

AMD also can release overclocked and pushed up RX 6950 XT or RX 6900 XTX in the coming months.

Low of 5fps don't look good.

Thats a massive microstutter there.

Could be nothing, could be drivers, could be infinity cache choke.

watch dogs legion has to cut its resolution by 60% on the series x to prevent drops at night in that game and when it rains in that game. Dynamic resolution may be critical for RDNA 2 ray tracing, there could be some sort of architecture bottleneck creating these stutters

a 7nm 3080ti would most defiantly be 10-15% faster than the 8nm 3090. If it's at 8nm then yes it cannot match the 3090. Please explain why GA100 cannot be used for gaming?

More to the point, why release anything else when you can't even get the card you launched a few weeks ago into a decent state of supply. RTX 3080 is still the fastest card around @ £649 and RTX 3090 is still the fastest card at any price point. Both are the only game in town currently for AI upscaling and hardware based RT. Big navi might have an answer to that soon, but as of today don't.

If/When AMD can advertise it's card in stock and has associated software available then the situation may change. I'm not sure that is going to happen much before the end of Q1 2021, which is probably when ti versions would be likely to appear anyway.

Tbh what swung me to get the Strix 3090 was the fact I run an intel platform
I don’t want to have to buy a cpu and board to get the numbers shown, I only wanted a gpu amd possibly swap to the 5000 platform next year
When you factor in the software and drivers will be weaker (it always is) then I was always going to stick with an nvidia card as much as I wanted to think I might go amd.

Personally I think AMD should have made more of an effort to promote these cards on Intel platforms as well as their own amd setups - millions of people are on the z390 chipset globally with most running an i9 9900k and they didn’t once embrace that or recognise that.

Whilst I understand the reasons to promote your own CPU platform this was a GPU announcement and anyone encouraged into buying an AMD GPU now on an intel cpu platform will certainly swap to an amd 5000 cpu in the near future - not to embrace and encourage that by giving numbers when plugged into a z390 board was an opportunity missed I think by amd and tarnished an otherwise impressive presentation, they should have thought about the long haul as well - and didn’t.
That said it is nice to see them challenging and innovating again and bravo

Yes agreed and this is what they are now doing GA100 isn’t a cost effective solution and I doubt any are used for gaming

I thought it doesn't have the necessary elements in the architecture for gaming.
Also there are no drivers for it, it has very expensive HBM configuration, it's designed for double-precision caluclations, not for gaming - millions of reasons why it cannot and will never be used for gaming.
Do you know that a system with 8 of these GA100 costs $199,000?

This is wrong - everything of it.
First of all - you can't buy a single RTX 3000 series as of today - sites say expect after November 15.

Also, AMD has said global launch date for RX 6800 and RX 6800 XT to be November 18.

Exactly the dilemma I am facing. I am on a 9900k and have a 3080 in my sights but AMD did not did not provide any charts on how good these GPUs perform when paired with an Intel platform like a 9900k/10900k. They should have elaborated more on the expected performance when not paired with a 5000 CPU as people with a 9900k/10900k won't be upgrading their CPU for gaming any time in the near future.

|I will bet it's normal for a six-core six-thread processor, no?

6 cores is plenty, doubt that lack of HT would make the fps drop to 5fps.

stooeh · 1 Nov 2020 at 20:26

Plus why would the GPU minimum be 5fps and CPU minimums 60+ if it was a CPU issue?

Hedge · 1 Nov 2020 at 20:33

No clue why people think amd should have demonstrated their product with an intel cpu.

I have a 5820k. Should I complain if Nvidia use a 10900k for benchmarks?.

6 cores is low end today. People already use 16 cores, 12 cores, 64 cores, etc.

It's the other way round - CPU is low, GPU is high FPS.

Nvidia are on the edge of their chips, people can't seem to accept this/

AMD is playing its cards still close to its chest.

So far, they have better board power which in turn also gives them more power headroom, RAGE mode can be increased in a patch allowing the gpus to actually have a greater power target, so far they have 20-50 watts to play with to match the current Ampere cards and possible go for more.

We do not know if 80 CUs is actually the limit of big Navi, remember, internally these are just known as RDNA2, its the consumer space thats spun the name big Navi.

Guessing game here, but I bet there is a 100 and 120 CU variant in the lab.

No, CPU is 5 - look at the orange and green curves:

stooeh · 1 Nov 2020 at 20:57

Those are frame times in milliseconds where lower is better...

that's not the framerate LMAO trust 4k8k to make a rookie mistake

harney · 1 Nov 2020 at 21:08

I am just happy i will be able to get a good performing card with ample Vram from AMD ..depending on stock obviously and with far less propitiatory rubbish Nvidia force on gamers & devs ect...Good on you AMD nice to see how far they have come with your gpu's
