I can confirm that my card power limits a bit less than before( with Palit bios just 2 times a dip for 1 second or so) but i can also see that im getting less average FPS with that bios in comparison to stock FE bios.
So 2100MHz Core and +850MHz on the Vram is giving me 65.80 +/- 0.05 @ 1062mV and Stock BIOS
Palit BIOS is giving me with exact the same settings 65.30 +/- 0.05
Thats 0.5 FPS difference in Time Spy Game Test 2
Even with a higher Bin (2113MHz) i can't reach the Stock BIOS performance, averging at 65,50 +/- 0.05 than.
So i would definetly say there is a performance difference between those BIOS versions.
Which ASUS do you mean the FE one or the STRIX?
I flashed the STRIX one on my FE card and couldn't get a display signal on Displayport, had to reflash other bios with iGPU
Edit: maybe worth to mention: If you not DDU after flash reboot and Windows is automatically installing NVdia drivers you pretty much excatly lose 0.8 FPS in Time Spy Game Test 2 ( at least in my case). The Point is its MANDATORY
to DDU your drivers after flashing and rebooting.
Are you seriously trying to say that 1/3 or .03fps is a measurable difference? We're talking well within the margin of error for the bench itself. Your services running at the time and the **** windows decides to do in the background during your test. Not to mention temperature influenced IPC performance and everything else involved. Simply running a test on fresh boot vs a hour after boot will post different results.
If you really want to test do this. Downclock your card to stock so you're not running at the limit. Limit the voltage for a reasonable bin below your stock boost clock using the v curve. Make sure that both bios hit the same clock and Vbin and you have no chance of pwr limiting at all. As in a blank GPUz graph. Then test the bios' Make sure that your load temps are within 2C of each other between runs as momentary temp throttled will affect your score hence selecting a lower frequency an Volts that make this less probable. Make sure your card, coolant if you are on water and radiator are desaturated completely between your tests.
I don't understand the physical instructions involved, unless somebody can suggest otherwise a reason one BIOS would score higher than another "bin for bin" "voltage for voltage". That is litterely all it's doing. Picking a vbin and feeding it to the card at a particular clock. I see no way for one BIOS (unless you are experiencing environmental" throttling to affect the cards performance.
What exactly else do you think the BIOS is doing that allows for variations?
Your reduced performance at the higher bin could be anything from error correction to memory distanilizarion at the higher bin etc.
Volts in at equal hz is equal W consumed. There is nothing extra special beyond that that the gpu understands. If you get your card to consume more wattage at your top bin without hitting temp throttles ofcorse you are gaining performance capacity it's just science.
Again 2000 at 1.05v is 2000 at 1.05v regardless of what BIOS is handing out that instruction. What you are suggesting is that X on BIOS 1 does not equal X on BIOS 2.
It's going to take a lot more splainin than .03fps to illustrate this. I haven't seen a true valid comparison by anybody yet. And I illustrated with my card hitting PWR vs not hitting PWR my that scores improved and I began to scale favorably at higher bins. Which makes logical sense as I get an extra 30watts of power to play with.
Keep in mind if you can't dissipate 30w of extra heat in that FE cooler, you will loose performance due to extra heat but if you can keep below or within a single Boost 3.0 temp throttle points on both the Palit bios and the FE bios you will gain performance capacity. There is just no other way around this.
In order for what you say to be true, the Palit Bios would have to be eating 30w as a snack making it 10% less efficient at the same voltage a variable so ridiculous given the basics of what a bios does that I can't think of a way for this to be true. And for it to loose performance, it would have to be even less efficient.Edited by KraxKill - 5/1/17 at 9:21am
