4090 Performance On PCIE Gen 3

NVIDIA GeForce RTX 4090 video card benchmark result - Intel Core i9-9900KS Processor,ASUSTeK COMPUTER INC. ROG MAXIMUS X HERO (WI-FI AC) (3dmark.com)

Honestly I'm quite Impressed, but I can't help but wonder how it would perform on a 12th Gen platform. 

Card is a Gigabyte Gaming OC 24G (Not my first card choice but they sold the Asus before I could make it to the store) The card has Thermal Grizzly paste and ThermalRight Extreme Odyssey thermal pads.

i'm seeing 27.5k after googling some scores, so maybe that 2% is from the pcie? I'm betting the cpu itself not the pcie gen 3 would hold it back in actual games.

Second place in the Port Royal test for all 4090s is currently held by someone with a 9900k so I suppose it cant be too bad.

IIRC, benchmarks for top of the line 30 series with pcie 3 vs pcie 4 showed a negligible difference on most games.

 

There's a bunch of factors that can play into whether pcie 4 makes an impact, and if the new Intel GPUs are any indication, GPU architecture might matter quite a bit. It's why Intel GPUs definitely have way better performance with ReBAR enabled, and perhaps the same with pcie 4, compared to the other 2 GPU makers where there's mixed results on ReBAR enabled.

 

All of this is complicated by how differently games handle rendering too.

Well the good news is your 9900k is worth a ransom in gold so you should upgrade lol. 

 

It's cheaper to get an 11700k and motherboard than a 9900k and motherboard sells for lol.

While true I don't think I can bring myself to part with it. She's a steady, 5.3GHZ, low temp, dream of a chip. Milled IHS and Liquid metal surely help.

Yeah well then you have a platinum sample of a chip lol. I don't know what to tell you there because you'd be right upgrading wouldn't give you much then...
