In any case the only reason Nvidia are able to cut the bus width down is due to the quite substantial increase in memory IC speed over the last 2 years, these are increases in performance Nvidia are not passing on to us, instead they use it to increase their margins.

AMD still offer a 256Bit or higher bus at $500+, as they did in previous generations.

The clue is in the name, its really simple.
Again its an enhanced 5nm process not true 4nm, the same with intel optimizing 14nm over a number of years.

The reason Nvidia is able to cut the BUS is because they used a large cache to compensate even though it doesn't fully compensate, they got away with it to an extent though because AMDs performance sucked this generation.

First you use TSMC's papers to strengthen your argument and then dismiss them when they don't, classic...

I don't think it does.. AMD left about 15% on the table with Navi 32, despite this they are still faster than the 4060Ti and 4070, once you unlock that tabled performance the 7700XT is as fast as the 4070 and the 7800XT as fast as the 4070Ti, they are also very much cheaper and the 256Bit bus helps the 7800XT in higher resolutions, as you would expect.

Besides that you should be more concerned with what Nvidia are doing, rather than blaming AMD for Nvidia's choices, AMD have no influence on what Nvidia do, none what-so-ever, so far as Nvidia are concerned AMD don't exist, so by-proxy 1D chess mental gymnastics to make the Nvidia problem AMD's responsibility do nothing other than reinforce Nvidia in what they are doing.
Its something tech jurnoes and NPC PCMR's have been doing for years and keep doing it expecting... (LOL) a different outcome each time.

What I find funny is that it must be cheaper to cut the bus width and add extra cache, otherwise Nvidia wouldn't do it. Yet we've been told that cache is expensive and takes up a lot of die space


The problem with cache is it's only useful until it's filled up, then the game relies on vram with its slow bandwidth. So wide bus, high bandwidth vram will be better than cache overall, until such time where we can have a very large amount of cache on the GPU (like 1GB of cache). Some of the early rdna3 rumours said the 7900xtx would have 512 to 1024MB of cache, but ended up as 96MB

It’s an enhanced version of TSMC 5nm called N4 but it’s not 4nm, kind of like with tsmc 7nm having N7 N7P N7+ etc.

Yea but it still has benefits as for similar performance AMD use more power to performance. Had AMD paid for this node they may look similar to Nvidia on power consumption. Googled it and it's 11% performance boost at 22% power saving. Probs to steep for AMD in the graphics world but shows that Nvidia had a hand up by going in this direction.

AMD didn't leave 15% on the table, they obviously had QC issues and had to scale back performance for stability. Some cards will OC some will not. If they could have got 15% more on each card then they would have done so and charged more for it.

I reckon on this node 15% would be possible. To gain 10-15% i need to use 40-50 more watts while undervolting so with 11% improvement off the bat and more power to use it's not far fetched. Also not sure how this would go in games as benchmarks allow you to push further. Mine is only an xt though so not sure how the overclocking goes on the xtx. With those benefits though am sure AMD could get close.

Most likely they did. I thought Apple were always first to the new nodes though. Either way Nvidia would have been paying a lot but they can afford to with there margins being so high.
Apple reserved 90% of 3nm already in 2020.... TSMC had some production delays on N3 but yeah, Apple thought they would be knocking out 3nm chips in 2021 or 2022.

Die size is at premium so cache is expensive in terms of die costs. Simple to design though compared to just about anything else.

Power saving too. If they had put in less cache in Ada then for the same performance they would have needed more bandwidth and then team green and team read would have been far closer this round for power consumption - especially if AMD had gone monolith on Navi32.
 
What RTX4070 twin fan would you recommend buying for a SFF case which has a GPU size compatibility of Dual Slot, up to 280mm in length, up to 125mm in height?
A lot of the gpu for sale on OC don't seem to show dimensions.

What are the "founder editions" of GPU's?

Cheers
