I tested right now the 2080 ti ftw3 vs my brand new Titan RTX under the same conditions at around 2000 MHz with no vram oc on air in BF5 all maxed out at 4k res. with dx12 and raytracing enabled.
With the newest driver the Titan is around 4 to 8 fps faster than the 2080 ti.
So the strange result of jay's youtube test where the 280 ti was faster was indeed a driver issue. The Titan is def. faster. In BF5 at 4k maxed out scenes in the single player with a lot of reflections fps go down to 40.
Btw my Titan RTX utilizes Samsung vram.
Power limit can be raised in AB up to 114% only
Max power draw was around 320 watt.
This card needs a powermod and has to get watercooled.
