Planning for GPU : 4080 vs. 4090

Sokonomi

I've been planning a completely new machine and i've squared most of it away, but I keep stumbling over the same block; what GPU should I get?

 

Budget is close to 'anything goes', and I can write it off as a tax deductible, though anything over 2000 would be close to the edge of my comfort zone.

 

My main goals are gaming, more specifically; VR gaming. I don't plan on streaming or playing competitive.

 

So here's my findings sofar;

  • AMD is regarded a bad choice for VR, as driver issues often pop up, so its probably best to stick with nVidia.
  • A 4090 costs 40% more than a 4080, but it seems performance scales almost linearly with it.
  • Upgrading last gen to current gen usually incurs a 50% loss, ie. a 3080 was 700 msrp at launch, now sells for 350.
  • Each gen does come with a usually big increase in core efficiency, 3080 vs. 4080 saw a 2.8x increase in RT throughput for example. So buying a top tier card in a bid to skip a gen might lock me out of such boons.

 

It boils down to 4080 vs. 4090; Do I buy the expensive cow and milk it for 6 to 7 years,
or do I go for the more sensible one and sell it for the 5080 when that comes out.

 

What seems more sensible?

if those are your two choices, I would go for the 5080 option.

 

Odd how you have no other options than those 2.

2000 us dollar?

 

40% more for the 4090 is pretty ok, for me difference its more like 70-80%.

 

Still the 4090 is kind of overkill for gaming, 4080 will do just fine.

 

Or get that 3080 for 350 and splurge on 5000 when it comes.

 4090s are double the price of a 4080 at the moment, Not worth the price increase at that point.

 

Do you want ray tracing? go 4080. 

 

What Resolution do you want to play at? 4090 is really only for 4k gaming to get the most out of it.

Well theres other options, but they are lesser than these two. I can grab a 3080 but whats the point in that?

I seem to have miscalculated a little due to tax return math. :') Its an 58% increase. So performance is not quite so linear I suppose.

Not double where I live, its about a 58% hike here.

And I only have a 1440p ultrawide, though its my VR headset (index) that might really push on it.

4080 seems more than fine. The index has 1440 x 1600 x 2 = 4.6m pixels, about the same of your 1440p ultrawide.

 

I wouldn't spend the extra 60% for the 4090.

RTX 4090 outside of those who can profit off of the extra performance just isn't worth it past MSRP. The prices now are high enough to make me consider breaking even with mine that I got on launch day, which are like +$2k reliably now.

 

RTX 4080 is closer to reasonable, but does struggle at high resolutions comparably. RTX 4090's memory bandwidth is nuts, which is a big reason why it annihilates everything at 4K. You can find plenty of benchmarks where the 4080 and 4090 are relatively close at 1080p and 1440p, but then its practically double at 4K. Depending on the VR headset you're using, that extra memory bandwidth could matter a lot.

 

Given the RTX 4090D China saga, we're less likely to see RTX 4080ti in my opinion, but that's just speculation on my part. Nvidia is likely sitting on millions of 14000-15000 shader AD102 dies that aren't being used for productivity/AI cards yet. Could always wait till the upcoming technology events and such to see if that nullifies my argument, but I wouldn't expect anything more from Nvidia unless AMD is standing by to disrupt the market.
