Yea they seem to be holding value pretty well. They hold a bit of a space for people because of the vram buffer, massive bandwidth etc. IMO they are actually great cards, sure they aren't the fastest gaming card in the world but as a do it all card - Perfect!

Yeah, it felt unfair when it got the slating, totally undeserved imo.

Can i ask why you need 120+ of those???

Also heres my current All AMD rig, and my side project :)

Nice - I recently sold my 20 or so mining cards... Im waiting for something new to play with.

Oh wait. on the ASRock 5700XT?

No, maybe on Ebay, i wouldn't sell it here, not unless i sell it cheap with a clear warning of what's wrong with it, i might do that to get some money back.

The 2070S is worth a lot more.

Yeah fair enough, might even be worth selling on the 2070s getting a good return and then putting that towards a newer card. Maybe keep the 5700xt as a spare?
 
Nerd porn, yes ^^^

£400 - I dunno I think we are looking at £600 :( I don't really want to spend £600.

But but but..... Nvidia said!

5700XT is and was £400< the 2070S at £500 was overpriced, trust me its overpriced...

If they are not going around 2080TI for around £450 i'm not interested, a 2080TI is not that much quicker than a 5700XT, or a 2070S.

Depending on what £400'ish cards Nvidia / AMD come up with that's a possible plan.

im in the same boat, If AMD hit the £400-£450 mark and be within a whisker of Nvidia, ill probably go for one. Although im honestly not sure i could get rid of my sapphire, its so pretty and performs so well

Well Lisa Su says she wants to make all the monies... You dont make all the monies by being some cheap second rate alternative. You make the monies with second rate alternatives that you pretend are the best.

I might just keep this GPU, its fine at 1440P.

I might be wrong, 2080ti at £400 - Sounds good to me. I think I might have to buy the big boy though... Whatever that might be. am hoping they actually just print "Big Boy Navi" on the box and make it obnoxiously large (like threadripper) because once you have handled the big boy CPU's everything looks pokey in comparison.

Yeah it must feel weird handling a CPU that's the size of an old smartphone.

This is where path tracing comes in - it isn't unduly troubled by polygon count and many other features which are part of scene complexity and can bring the benefits of the fundamental advancements of ray tracing to games with results that are passably close to a proper full screen, full scene complex ray tracer for gaming purposes. It brings the reality much closer much quicker IMO than people think - sure you have to be a bit selective on how many of the sources of light actually do have a reasonable degree of additional light bounces, etc. (ideally you need around 4x the ray budget compared to Quake 2 at 60+ FPS to avoid noticeable artefacts from the limits of the denoiser and the way light is sampled over multiple frames for performance reasons).

People don't realise that the path tracer in Quake 2 doesn't take advantage of the low geometry and other low complexity of the engine as the Minecraft one does, which is often assumed by the doubters, if you scale up the scene complexity by say "64 times" (high resolution meshes, more shader effects, etc.) you only get a ~4% drop in performance. If you increase the complexity of the path tracer itself you will see a bigger performance impact but that is another matter.

A lot of the problem right now is the lack of people with ray tracing hardware - the token effects in many games come with much of the overhead of a fuller ray tracing implementation but have to remain as token effects so they don't affect the ability to simply turn them off for people without the hardware and many of the ways traditional rendering fakes up graphic features conflicts with the wider use of ray tracing and most developers won't go to the time and resources to maintain two branches of the game or having a plainer looking game without ray tracing.

You're right the issue is way more nuanced and performance scaling is oddly not that linear. There's also the problem that the RT portions are done on dedicated hardware that isn't easily generalized to other tasks so you don't want to make a new generation of cards with too much of the chip dedicated to RT ops as it means less rasterization power, and turning down other settings like say texture resolution may not help in scenarios where the RT cores are the limiting factor, so altering in game settings may have counter intuitive behaviour.

Part of the reason I see this being a way off yet is because the GPUs in any specific generation have certain amount of transistors to dedicate towards different parts of the GPU. And more to RT and Tensor core Ops mean less for rasterization. People generally speaking demand to get some general performance increase between each generation so this is a hard sell, to give them less in one area to enable some RT. This is why I think it'll be a multi-generational transition, probably over 20 years. We'll slowly move the hardware itself towards more ray tracing focused effects, then buy-in from developers and gamers then a move to do more and more. You couldn't just produce a card now that was mostly focused on full path tracing and was super good at it but couldn't render current games very well, people wouldn't buy that.

You will buy the big boy Vince.. you will... <evil laugh>
