4080 products with different clock speeds

[willseremak]

I have noticed that 4080 brand have different clock speeds. 1. Can I change the clock speeds? 2. If I can change the clock speeds, would it just be best to buy the lowest priced 4080 that has a S, A, or B tier temperature/cooler rating and then adjust the MHz? 3. How do I change the clock speed?

It's just factory boost OC. It's really minor in the grand scheme of things and is basically irrelevant in real usage.
1. To an extent, using something like AfterBurner, sure. Raising Power Limit might be more useful than messing with clocks directly.
2. I would ignore rated clocks anyway and focus on the cooler and price. The card will boost itself higher than stated in almost every case.
3. See 1. Ultimately not much point.

the reference boost clock on cheap cards and the NVidia Founders Edition, slightly higher boost clocks at higher end cards. more important is the fact that higher end models have a higher power limit.
you can change the Core and Memory Clock, Fans and Powerlimits to whatever you want with software like MSI Afterburner.

and something that i've noticed over the years:
A ROG Strix with a 100 MHz higher boost clock does not actually guarantee that the card actually clocks any higher than a 100MHz "slower" low end model from lets say Palit. it has been completely random for me and never what they claimed.

For practical purposes, better cooled cards will have better clocks, due simply to the physics that the same GPU would consume less power at a lower temperature but the same clock and workload, and will boost higher at the same wattage.

The usual "Base" and "Boost" clocks have long lost their meanings other than for reference, for GPU clock. AFAIK a lot of them overclocks to a limit significantly higher than any posted numbers now.

Personally I don't even care about the factory OC, I just care about the cooler (unless I plan to watercool) and the price/performance of a graphics card.

For practical purposes, better cooled cards will have better clocks, due simply to the physics that the same GPU would consume less power at a lower temperature but the same clock and workload, and will boost higher at the same wattage.

Also the power limit can make difference with the same GPU between models.

No point really for looking at those clocks. Tell you almost nothing
If you are on the market for 1 then search for reviews/comparisons of different AIB 4080 cards and get the one more appealing to you.

Gaming performance
Cooler performance
Power consumption
Overclock and undervolt ability
Price

...are some aspects, most users are interested in.

Use the boost switch instead of silent. Otherwise once they hit 40c or so they start to down clock. Plus having air from GPU fans running is better for the card.

Depending on the cards silicon lottery, how it cools itself and case design is what matters.
Use MSI afterburner to adjust core and memory clocks.and change the way the fans come on.

Ensure hwinfo64 and/or GPU-z to monitor temps of memory hot spots, GPU die, fan speeds etc.

Start with a simple benchmark like heaven. Run an overlay (if you know how) to see how hot it is already getting before oc
