Ryzen 7 9700X Extreme Undervolt & Overclock to 6325 MHz | SkatterBencher #80

YES, SHOW THEN THE TRUE POWER OF THE 9700X. The 7800X3D when well tweaked

[@puffyips]

How it should’ve been released but no it’s often a 5800x3d competitor

[@deadman5985]

Nicely done! 👍🏼 Do you think the lack of increase in gaming performance could be because the memory controller isn't fast enough to feed the cores? If so, X3D versions might scale even better this generation.

[@SOLIDNecro]

it could be that the 2080ti (2 generations old) he's using is maxed out by the cpu even at ambient temps, so raising cpu speed wont realy help. If he had a 4090, the CPU would be a bottleneck, so higher CPU speed would show improvements.

[@deadman5985]

@@SOLIDNecro I totally missed that, thanks. Yeah, might well be mostly GPU-bound.

[@SkatterBencher]

The lack of gaming performance scaling with much higher frequency is a bit puzzling, however there is an element of GPU-boundedness with this RTX 2080TI. That said, usually CPU frequency always helps performance even if it's just a couple FPS. Even in extreme GPU-bound scenarios (because the CPU is always there in terms of fetching data from memory or processing some data). For example, I've gotten to 207 FPS in Tomb Raider with this GPU and another CPU. Also Final Fantasy sometimes goes over 200FPS with other CPUs. It feels weird. I also tried the RTX 4090 with this CPU on ambient and there was a similar lack of scaling. I don't think it's related to memory. Otherwise we'd see performance improvements with FCLK/UCLK/MCLK increases or memory timing adjustments. My gut feeling says the bottleneck is somewhere in the uarch backend getting the right data to the right places at the right time. Because it doesn't matter how fast you can process data if you don't have the right data to process since you'll need to wait additional cycles. This is just speculation, however.

​@@SkatterBencher Very interesting theory, would be great if you could comment on it in a future video if you find the root cause.

[@julfy_god]

would be nice if amd will give full control over vft curve(like raising freq without limits etc)

[@arturb5152]

AMD architecture scales poorly in games relative to clock speed 😞 I would like to see how far can You push R7 9700x on Noctua tower 🙂

[@NVMDSTEvil]

Might be interesting to try a tec system set up to hold the cold plate just above ambient to get optimum ambient temperature performance. For gaming loads this wouldnt be too much for power probably.

[@SkatterBencher]

It's a cool idea! I won't pursue that goal but hopefully someone else on youtube will try it :)

[@NVMDSTEvil]

@@SkatterBencher derbeaur has that intel one that might work with a bit of trickery

[@panjak323]

6.3 GHz is not that impressive on LN.

[@SkatterBencher]

In OC Mode it certainly could go higher. But has anyone reached a higher frequency with Precision Boost enabled?

[@Sir_Defyable]

Clock speed is not that impressive of a measurement metric when related to CPU performance

[@SOLIDNecro]

@@Sir_Defyable Most get that, but his point was in comparison to what others have achieved with the same cpu on LN-2. SB is right on the money though, pretty impressive just using PBO and E-Clock!
