Anyone planning to buy the RX 6900 XT, rather than RTX 3080?

Without wanting to pour fuel on this particular dumpster fire the humble 5800X overclocked scores are beating the 5.3ghz 10900k in a good number of games.

There is also a cost involved with getting a binned and de-lidded 5.3ghz 10900k, i paid £800 for my 9900kf.

For 10900K you need a huge cooling solution to keep it below 100C at 5.4Ghz for long periods of time. For the videocard, you need another good cooling solution, Nvidia creates more heat than AMD. It can be done but at a very high price, a lot of noise and if one is happy with his CPU running at 100C then good for him. That's why i said the 3d mark scores are different from real life usage. In real life you disable HT or some cores on the 10900k to keep it at a decent temperature with an extreme overclocking.
Meanwhile you can get 5900x or 5950x and a 6800xt, use a mild overclock and get pretty much the same performance. And you won't have an oven instead of a PC. :)

You delid and a chiller can do it easy. Its got to be a gold sample only, a rare chip for water.

NVidia are not 7nm, they are 8nm. 8nm Samsung becomes better as you water cool. This is because the power draw can drop. So people state that it can drop to 60% power draw, just by cooling to 30c. So as you cool the temperatures drop. The chip then can overclock to 2.2GHz and stay at 30c. The issue is the more temperatures increase the less efficent 8nm Samsung becomes. The more power you draw.

Good cherry pick, that game loves AMD cpu's. This is the truth here:-

https://www.techspot.com/review/2132-amd-ryzen-5900x/

. The question now is, for gamers looking to build a high-end system, which CPU should they buy, the 10900K or the 5900X? For the vast majority of people, it’s not going to make a real difference. Performance is going to be roughly the same, and even when CPU limited 99% of the time, you won’t be able to tell the difference.

Both the 10900k and 5950x overclock to about the same performance in time spy cpu. Picking one of the top overclocking 10900k's @ 5.4GHz (here is a 10900k @ 5.4GHz on water https://youtu.be/cssbWlpmTho) and 4500MT/s RAM you have a monster gaming PC that will beat all AMD cpu's stock in games and almost all AMD ryzen cpu's in games when all cpu's are overclocked.

This is with a Intel Core i9-9900K @ 5.0 GHz and an AMD cpu only for SAM. AMD cpu has its IF overclocked to 1900 which is a big deal for game performance. Thats what the DDR4-3800 RAM means. Graphics cards stock.

Then there is the rumors of 16% increase for SAM (Re-Size BAR Support) on 10900k. This makes the 10900k the go to CPU for games if true.

Yeah this kits doesn't like gm off even much lower frequency like 3400mhz. I can tighten much more but performance gain is very low or decreases. Also 4x8 works slightly better with my system don't know why. https://www.3dmark.com/fs/24139421 First 60k graphics score in the world taken by 4x8 kit and thats funny. Even the brands not same :D

@betsy you can see at the picture just below the "GRAPHICS" says high which is the selected preset. Best preset is "highest" and gets 94fps.

Filling the slots normally reduces the maximum frequency but the RAM becomes Dual Ranked which adds performance. Firestrike is a light graphics load, it only needs a GPU with a few GB's of RAM.

Do you know what's the difference between standart run and custom run without changing anything? I always getting better score with custom run.
Click to expand...

Custom run can be different on Ryzen but not on the 10900k. 10900k is fixed frequency with no boost. Boost on ryzen likes good cold water temps you get on startup. 10900k you can run it a few times because sometimes background tasks affect the score. 10900k wont get higher for just running the cpu test. Its 30k and that wont change. The 3800x will get lower if run after the graphics tests but sometimes you do get the same score. Once the water heats up the ryzen cpu will change but the 10900k wont change.

16% LOL. First SAM benches are out , Intel gains 2% at best and negative 1% at worst

6800xt is now more than 300 points ahead on Timespy average. It is not much but it shows it is a better overclocker than the 3080.
Click to expand...

The only reason why 6800XT is scoring higher is the fact that it is quite easily overclockable to 2600-2700 Mhz range just out of the box on air cooling.
Also the reason why you see the bell curve further back on RTX 3080, most of the cards do not even get to 2000-2050 Mhz on air.

The water-cooled cards on the other hand, are easily reaching 2200 Mhz on the RTX 3080 without any hardware modding, on the other hand water-cooling 6800XT is completely useless, since you are driver limited to 2800 Mhz, and you can nearly reach that on air alone. If you compare a water-cooled 3080 to a water-cooled 6800XT the 3080 wins every time.

Another thing to have in mind. Even if they unlock the 6800XT clock limit, that doesn't necessarily mean that it will scale much above that number.

No the best 6800xt on ts gets higher score than the best water cooled 3080. When 2800mhz limit overrided ln2+3080 scores also be less.

3080: https://www.3dmark.com/spy/16555592
6800xt: https://www.3dmark.com/spy/16594315

ln2+3080: https://www.3dmark.com/spy/14039907

Plus, most prob 3080's score is only valid for a short time. After that it will be unstable to keep it.

I was pointing out the average scores of the cards, not the highest scores. No one cares about highest scores, and even if we did it is 100 points difference, that's practically nothing.

The main point here is that most of the reviews on the internet for the 3080 vs 6800XT are done on that average point on the curve, and that point on the 6800XT is much higher than the one on the 3080 because you can easily obtain it on air cooling. And in those reviews both cards are trading blows in different titles, and resolutions.

If you put both cards in a custom loop on water, the 3080 overtakes the 6800XT by a healthy margin, we are talking here with SAM disabled of course.

2200Mhz 3080 is daily stable on water quite easily on most of the cards.
