Aug 30, 2022 · Ryzen 9 7900X A step below the 7950X we have the Ryzen 9 7900X. So, ultimately, we don’t expect that much performance At 90w cpu power (or 125w PPT LIMIT) Clock speed caps at 5g (instead of 5. Jan 4, 2023 · That said, I did attempt to set an 85C limit (without a PPT limit), which the 7900X obeyed, but got much better results with just the negative curve + lower PPT limit Depends on what you're aiming for. It's just when pushing your architecture to its limit with factory voltage settings to account for Silicon variance, voltage increases drastically and amperage linearly. 5% multi core @ same PPT with following changes: -45mv vcore offset. This will plateau at a certain point. AMD 【PPT Limit】:指的是CPU长时间功耗，如果想要完全去掉功耗墙只要设置成最大值即可 【TDC Limit】:指的是CPU长时间电流，同样，如果要去掉电流墙就把这里设置成最大值 【EDC Limit】:指的是CPU短时间电流，如果要去掉电流墙就把这里设置成最大值 Jul 26, 2024 · Especially for the higher core-count CPUs. From our testing we have found that there is crucial difference between TDP and PPT. PPT: Package Power Tracking Sep 30, 2022 · Optimum tech achieved a 30c and 50w reduction just with curve optimizer, setting a lower ppt and changing the thermal limit. 25) Temps went from 88-90c to 55-57c in my current system with 2x360 rad custom loop (again, not controlled environment.

Ryzen 9 7900x consumes up to 208 watts even in power saving/eco mode. What’s happening here is that the 7900 at stock is hitting the 88W PPT limit out of the box. May 26, 2022 · The package-power tracking (PPT), a figure that translates as power limit for the socket, is 230 W. Jul 11, 2021 · 2、【PBO Limits】 该选项是配置PBO2的插槽功耗【PPT】、供电电流【EDC】、功耗电流【TDC】。 如果你散热和主板足够优秀，散热至少满足240水冷，主板至少满足8相*40A供电，那么为了获得最大性能提升可以选择关闭。 PPT can be as high as you want, TDC should be lowered if you feel it peaks at high temps but another (just as good) solution is to use the "Thermal limit" in BIOS. As 125W + Curve Optimzer -30 applied, the Cinebench nT performance is close to stock Ryzen 7900X. While testing CPU coolers, I observed the importance of adequate cooling in achieving and maintaining maximum boost frequency. Base clock of the new TSMC 5nm-fabbed chip is listed at 4. Of course, there's nothing wrong with these CPUs running at 95ºC 24/7 - Oct 6, 2022 · Whatever the actual reason, it's clear that Zen 4 users interested in tweaking can drastically reduce the power consumption of their new CPUs without shaving too much performance off the top.

EDC/TDC - have more of a sweet spot as opposed to “higher is always better”, because if you just set these to 200 each then your CPU will just use the highest voltage allowed by FIT to boost (thus chewing up more PPT), when it could potentially be able to use a lower voltage for the same frequency if the EDC/TDC was set lower. This is another two CCD part, but with only 6 cores enabled on each CCD for a total of 12 CPU cores and 24 threads. Up the EDC value in increments of 1 until you hit 98-99 never 100. Update 1: Improved to +1% single and -7. We observed that this value can be adjusted in the BIOS or AMD's Ryzen Master software. The X version has a higher stock limit, and applying PBO to the non-X effectively removes the limit entirely. 70 GHz base, with an impressive 5. Overclocking. The 7950x has 16 cores to the 7900x's 12 cores, so I raised the PPT limit to 60W, and it now scores 20205 in in CBR23. 142W PPT ~ 105W TDP 88W PPT ~ 65W TDP 65W PPT ~ 45W TDP (possibly) 45W PPT ~ 25W TDP (possibly) Not completely sure if the 65W PPT and 45W PPT are an accurate simulation of their TDP counterparts, predicting power consumption is very messy in the laptop space where Nov 23, 2022 · Ryzen 9 7900X has 12 cores and 24 threads with 76MB of total cache – 64MB of which is L3. My target was stock ST/MT performance, and lower power draw (and temps) The power figures they show for this are PPT limits, aka actual power draw.

May 6, 2024 · I have done lots of research and tinkering to cool the 7800X3D with little to no performance loss in gaming and everyday workloads. Here is a quick look at the new 65W Ryzen 7700 performance gain with different PBO settings. Simply put, higher TDC usually means higher clocks. 08v. All while maintaining stock out of the box performance on a 7700x. Reply Nov 2, 2022 · The Ryzen 5950X was limited by its 142W PPT limit before it hit the temperature limit; The Ryzen 7950X has more power, so it will hit the temperature limit before hitting the 230W PPT limit. I finally set on 75W, still using the -30 negative curve optimizer and +150 MHz positive PBO clock. Jul 18, 2023 · With a whopping 64 MB of L3 Cache and a base clock of 4. You could set PPT to 300W, but if your TDC is limited to 50A you won't ever hit that 300W limit. I would guess this is because dropping PPT Limit actually causes the CPU to use the more efficient V/Hz curve points at the cost of reduced performance, whereas undervolting still uses the aggressive ~4Ghz voltage curve point (less efficient), but still loses performance regardless due to clock stretching. . 7600X and 7700X – PPT 88000, TDC 75000, EDC to 150000. Let’s dig a little deeper into the algorithm behind this intelligent behavior: Precision Boost 2, or “PB2”. What is the difference between TDP and PPT.
