Nvidia Ampere Discussion [2020-05-14]

I'm just not going to spend $1500 on a gaming card and another $200+ on a waterblock & backplate. First time in a long time since Kepler I'm going with the x80 model instead of Ti or Titan. Probably even stick with the stock cooler for once too. Feels weird to only spend $700 on a video card and still be getting a massive upgrade. I guess I shouldn't complain to get 80%+ of the performance for less than half the price. Put the extra money towards another OLED display

 

7 GPC is accurate, I believe.

Apologies.

 

If you mean from AMD I'd think it's complicated. In general I feel that enthusiasts somewhat over value how important the direct AMD vs Nvidia (or Intel) product competition affects the business side, not saying there is no consideration just that there is way more to it.

This is of course all going to be idle speculation and just some ramblings but -

1) Nvidia competes more than against AMD's PC GPUs. Regardless of what AMD does the upcoming consoles need to considered.

2) Nvidia also to some extent needs to compete against themselves, as you need to convince existing users to upgrade. It's been mentioned in past that Nvidia's marketing really targets more so 2 generation upgrades. This is why I speculated they would be aggressive perf/cost wise relative to Pascal.

3) There's actually opportunity here to grow the overall market due to the Covid pandemic. The pandemic situation has actually been increasing interest in gaming as an activity in lieu of other physical options.

4) The word is the cost structure of using Samsung is much better in terms of both wafer costs and mask costs. Availability might as be better meaning a volume push is more viable. It doesn't make sense to push for volume if you can't supply it after all. In terms of FE pricing my opinion on that has always been it was done to capture more of the money going towards the sellers with initial launch availability issues. It's interesting to note that with the "refresh" releases (1080ti, Super) there was never a higher FE price.

5) Part of Turing's pricing issue was likely coming off the heels of the mining bubble.

6) Personally I've always felt that the broader opinion with respect to AMD vs Nvidia pricing is actually off. Nvidia has actually more often taken the initiative to push perf/$ forward with new releases than AMD and set the benchmarks. AMD is more reactive one. They often price lower due to market necessity which gets interpreted as AMD setting the price to keep Nvidia "honest."

7) We might also want to wait to see how the current "theory" with regards to performance actually works out in practice.

 

The new video engine really has av1? Why didn't they say that, it's a huge thing imho.

 

@ShaidarHaran
Maybe this time you shouln't buy any nvidia card an price will drop fast? Thats the way captialissm work. If you buy a 3080 Nvidia will win.

 

3090 should make 4K Horizon Zero Dawn playable...

 

FMUL is 2 flops but can be pipelined every cycle, so they count that as 2 flops. That's always been the case for this and previous gens too.

 

Anchoring works well. Now people think the prices actually went down, whereas really they're just not charging the FE "tax" this time. Do I think Ampere is worth the asking price for what you get? Yes, definitely. But I'm not going to get all warm and fuzzy at Nvidia for not gutting consumers completely this time around.

 

I assumed that was the case when watching that part.

 

So if I read that chart correctly, 2xFP32 cores will not translate into ~2x rasterization performance. I suspect only 1xFP32 will be used for shading, the other FP32 exclusively reserved to support Raytracing. Or is it because engines aren't programmed to used both FP32 cores concurrently?

 

From the limited info, looks like 40-50% improvement at each respective tier when we ignore Nvidia marketing shenanigans.

 

"N" in 8N means NVidia, no? Somehow "much better" seems really unlikely. But it's moot really, gamers are going to be paying with extra electricity $ because JHH thought he could Apple TSMC.

 

Performance depends on more than just flops. 3070 bandwidth is lower than the 2080 Ti.

 

I think 3090 might be up to 70% faster than 2080Ti. Maybe more in some games: 1.4x for 3080 over 2080Ti and 1.2x for 3090 over 3080.

 

Agreed. That's what I was seeing based on their charts.

 

Watching now
Edit.
Beat me to it @Man from Atlantis

 

Impressive, very impressive... You know it is when they show that they are not cheating

 

According to DigitalFoundry: 2080 to 3080 is 65% to 80% or 90% to 100% more in RT games.

 

Yeah but then why put twice as many in if memory bandwidth can't keep up? Those charts to me really just show the performance increase of 1xFP32.
