Rumour: AMD's 4096 Shader Big Navi in Q4 2019?

Pinch of salt guys but i think a GPU like this is well with in the realms of possibility.

The current 5700XT has 2560 Shaders, 4096 would be +60% Shaders

The 5700XT is a small 251mm^2 GPU, in terms of die size its a HD 7870 or RX 580 type GPU, so it does have a lot of room to grow, i think its inevitable that it will, and maybe at the end of this year.


 
It's always been obvious that the 5700XT isn't the high end despite some recent rhetoric from some.
Which is why the 5700XT's price is such a disappointment as it's a really good performing mid tier part.
 
Agreed on both counts, tho still cheaper than nVidia, 2070 Super £500 vs £380 for 5700XT
 
I think we would need to know how many teraflops to estimate it's performance (if it exists), so we can compare it to the 5700 XT.

That's easy, assuming the same architecture, no tweaks or improvements, at the same clock speed: 15.6 TFlops FP32, the 5700XT is 9.75 TFlops FP32, simply add the 60% CU's to that.

However, with that you can only compare the same architectures, not even AMD's other architectures are comparable, Vega VII has 13.8 TFlops FP32, about 40% higher than the 5700XT yet in games Vega VII is only 5 to 10% faster, this is because Navi is a vastly more efficient gaming GPU.

From hints buildzoid & Jay2cents have said that CES2020 will be the date the bigger GPUs will be out. That means well into March next year to see them.

And I hope AMD & Nvidia come with a big indium soldered IHS for the next 7nm chips, because 251mm^2 is too small surface to cool 200W effectively on air.

I hope that's right, but 15.6 TF could mean higher performance than the RTX 2080 TI potentially. So I think that's a bit optimistic.

Also, I'm not sure where he got the 4096 SP figure from. The image below on the twitter post is just a list of product codes isn't it?

Not really, because AMD have had to use their Ace (going to 7nm) to be able to compete. Nvidia still have that in hand to use at a later date.
 
It's possible we won't see large improvements until 7nm+ . AMD released their most powerful GPUs first for the Vega and rx 500 series. Then, they waited 1/2 years to release the RX 590 and Radeon VII.

Why? I'm not offering an opinion on comparable performance at this point one way or the other, just to point out what it looks like you're saying, in that the numbers look like it might surpass 2080TI performance, and for that reason cannot be right? Why? do the laws of performance stop at the 2080TI? is that the MC=2^ of GPU's?

That would be a shame, i was hoping for more in time.
 
Ultimate performance is likely to be 1.6x 5700XT based on shaders but then clocks reduced by ~20-25% to get it down to a 300W power envelope.

Puts the likely performance around the 2080 Super without other enhancements.
 
I'd imagine the 2080 Ti would be bottlenecked much of the time at 1080p and some of the time at 1440p though. Plus TechPowerUp's numbers are generally less than worthless to begin with. Their average rankings sure can't be taken seriously when Ace Combat 7 is a part of the suite of games, given it's one of the most vendor-biased titles I can remember. Using it as a performance benchmark is laughable.
