Is a 3090 eGPU viable? I'd say so!

I plan on uploading a full build and comprehensive benchmarks with comparisons, but in the meantime, I just couldn't wait to show off this one result in particular. I just hit 10,202 graphics score in TimeSpy Extreme: https://www.3dmark.com/spy/14160383

which is higher than the current average DESKTOP 3090 score of 10184:  https://www.3dmark.com/search#advanced?test=spy%20X&cpuId=&gpuId=1339&gpuCount=0&deviceType=ALL&memoryChannels=0&country=&scoreType=graphicsScore&hofMode=false&showInvalidResults=false&freeParams=&minGpuCoreClock=&maxGpuCoreClock=&minGpuMemClock=&maxGpuMemClock=&minCpuClock=&maxCpuClock=

More to come!

@bmagnien, nice! My 3080 hits 8060 on GFX in the test, so I'd say yes, the 3-series is very viable, especially once they fix the drivers, should see even more performance.

I would hope so, it seems to only be about 15% faster than a 3080

@bmagnien -  very stupid question here, but, were you using the card in an epgu enclosure? if so, can you say:

- what model enclosure you were using?

- which version of the 3090 you were using (Nvidia FE or one from Zotac, Gigabyte, MSI, etc)?

I've got a Razer Core X and I've been wondering if it'll fit, and work, or not.

@dlpasco, not a dumb question at all, I would’ve been more detailed but I’m preparing to publish the build with full details and results in the next couple days. It’s a evga rtx 3090 FTW3 ultra in a Mantiz Saturn pro 2 case. I went with Mantiz because of the 3 dedicated 8 pins and the 750w cpu. I believe the razer core only has 2 dedicated 8 pins, a 650w psu. Remember 100w of that will go to laptop power delivery, but you should still be good for most 3090/3080, just make sure you pick a model that only needs two 8 pins, and has a 2 slot io bracket, even though the card itself can be up to 3 slot in width for your case. And then check on the razer website for max internal gpu size to finish off height and length checks. I know many 3080s and 90s will fit your case.

@dlpasco, Yep all of @bmagnien advice is spot on, just to add I'm running a 3080 in the razer core x case and it runs fine. Just make sure to get a 2 x 8 Pin card.

Holy crap, has anyone tried undervolting their card? I've got a stable card at 1950mhz undervolted to 0.9mv (down from 1.1), it's running 10C cooler and saving roughly 100watts for the same performance.
