The delta between 7700k and 8700k comes down to modern engines being able to core scale. Frostbite for BF games, Foundation Engine used in Tomb Raider games are examples that core scale well.

Yeah, it's a poor comparison in the sense that IPC is very similar, the core count being the primary differentiator.

They did bring this up and SOTTR benefits heavily from DDR5 and even that crap DDR5 was beating 3200 c14 on 12900K
Would be nice to see DDR4 4000C14 on both

If they said 40/4800 ddr5 brings a benefit then they’re really quite clueless. 40/4800 is absolutely awful for ddr5. You need to start hovering 6500+ and tight secondaries to get something serious out of ddr5.
Buying 40/4800 is a great way to choke an adl system. Here’s a 12900k with tuned ddr5 at the same spot as their test.
6500 1T in the same area from one of our discord guys. This is without resolution scale that 5800x3d guys used:

165 watts in a game? "power efficient in games"
6400MT/s RRD5 RAM is £450.

it’s a 40/6000 kit tuned…I literally said tuned ddr5 in what you quoted?
Caporegime
Tuning is no guarantee, getting £250 5500 MT/s to run at 6500 MT/s is not a given, and its still £250 RAM.
Also, and I'm sorry to bring that up, but with all the "oh but its really power efficient in games" rebuttals; 165 watts in a game is insane, its ridiculously high.
Caporegime
Is that part of the game accessible in the demo? i want to see what my £90 RAM gets me but i'm not paying £30 for the game just to find out.
Soldato
Here we go again, confusing consumption with efficiency. It can consume 5000 watts and still be efficient. Efficiency = fps / watt.
Caporegime
Gaslighting, you're full of tactics to try and throw people off aren't you?
In his case he's using 0.49 watts per frame.
The 5800X3D is using 0.25 watts per frame.
Just in case its not clear to you, the 5800X3D give in this example in 2X more efficient.
I didn't need to do that bit of maths to see how inefficient it was, its obvious. Its using a lot of power for what its doing. Which is the point i made.

Because it's overclocked to 5.4ghz. How efficient is the 5800x3d overclocked? Oh wait

Clock speed is irrelevant if you can get better performance through innovation as the 5800X3D does.Because it's overclocked to 5.4ghz. How efficient is the 5800x3d overclocked? Oh wait
Soldato
I agree, but the point is that an oced cpu is going to be inefficient usually

More than that, more than its self.

I’ve never cared about it. Intel could be twice as fast as AMD or vice Versa. It wouldn’t make any difference.

Interesting that a cpu has to be massively overclocked to *just* beat the new AMD part; is that a £3000 pc to beat it?
Soldato
Even if the freequency scaled linearly, it doesnt need to be massively overclocked. It beats it even at stock if you run the numbers. Actually it even beats it undercooked. In fact, even the 12700k will get very similar numbers with the same ram. The 12700k costs less than the 5800x3d will. So yeah...
Soldato
So a £3000 massively overclocked PC beats an unreleased part using a bios and drivers which dont support it. Thanks for confirming!
Caporegime
Its 330 FPS @ 4.45Ghz 85 Watts vs 342 FPS @ 5.4Ghz 165 watts
For 21% higher clocks and 100% more power that overclocked 12900K is 3% faster than a stock 5800X3D.
I think if @Robert896r1 was completely honest he would agree he pushed the chip and the memory until he got that +3% on the screen cap.

Yes, a massively overclocked pc beats a non massively overclocked one. What is weird about it?
5800x3d has to compete with the 12700f (310 euros as of right now). It probably loses to multi and singlethread and it only wins at 240p gaming,while bring 50% more expensive. Are you sure you want to bring price into this argument?
