PCI-e 3.0 x4 for ampere 3080/3090 question
First of all, I found an article where someone tested the 2080ti on different PCIe lane settings to see what the performance drop was for the 2080ti using x4 over x16, and overall it showed an average of around 5% drop, up to 10% for a few games. This is reasonable.
Can we expect the same for ampere cards, or will they be so bottlenecked on a x4 that the drop will be exponential?
I'm considering buying a 3080 or 3090 for my alienware graphics amplifier (fitting it wont be an issue for me and my aga has a 750 watt power supply), and maybe later down the line in half a year or a year buy a desktop around the videocard.
I'm currently using the 51m R1 9900k 2080 (I also have a 4k 144hz display that can use all the graphic power it I can throw at it), will I see a massive performance increase using a 3080 or 3090 in my aga or should I just save some money and buy a complete desktop system, because who knows by that time 4080 might be out and its not worth aga'ing an ampere card at the moment?
Until these cards reach the hands of end users, any answer you receive is speculation.
Even the ones in the hands of early reviewers are pre-production prototypes at this point, which may or may not reflect the hardware that will ship for sale through end user channels.
It’s going to work as some website said nividia confirmed that it would still work fine with 3.0 as long as it’s x16 but I don’t know about x4.
I’d still use the RTX 2080 in the area51m for now as it’s still powerful and I’d wait until Dell updates the graphics amp to x16 gen 4.0

Thanks, I'll keep an eye to see if anyone benchmarks 30 series on different PCIe 3.0 set ups, but I had a good think about it and I'll probably wait until I've got enough for a full desktop system.
Your welcome.

I have an Area51m 9900k, 2080, and AGA with a 600w PSU. I received my PNY RTX 3080 from Dell today and cannot get it to work with my internal display or HDMI out to a monitor. I have the most recent 456.55 Game ready driver from Nvidia and the latest updates for Win10 Pro. The card is recognized in Bios and in Device manager. Device manager states: This device is not working properly because Windows cannot locate the drivers required for this device. (Code 31) Insufficient system resources exist to complete the API. I’ve searched high and low and can’t find anything that helps.

Try turn it on with the AGA connected, when the Alien Logo show up, turn it off by pressing the power button and then turn it on immediately.
Let me know!

All...I downloaded a new bios upgrade today and after installing, my rtx 3090 now works with my aga and the led light is on. No more swapping tricks with the cable. Able to restart, put in sleep mode and external display with aga comes back on with no problems.
