Core Performance Boost Contributes 14% to Ryzen 5 7600X Cinebench R23 Score
AMD Ryzen 5 7600X "Zen 4" 6-core/12-thread processor is shaping up to be a speed-demon for purely gaming builds, with the company claiming higher gaming performance than Intel current flagship Core i9-12900K. A combination of high clock speeds (4.70 GHz nominal, 5.30 GHz max boost), high power limits from 105 W TDP (130 W limit), the "Zen 4" IPC, and the fact that all that power headroom is available to just 6 cores, means that the chip is able to sustain boost frequencies better. But what when Core Performance Boost (CPB) is disabled? VideoCardz scored screenshots of a Cinebench R23 run to answer just that.
With CPB disabled (in the motherboard BIOS), the Ryzen 5 7600X scores 1681 points in the single-threaded test, and 13003 points in the multi-threaded one. With CPB enabled (which is the default setting), the 7600X bags 1920 points single-threaded, and 14767 points multi-threaded, which is a 14% performance increase just from the processor's boosting algo. Disabling CPB is generally seen as a silver-bullet against high temperatures for AMD processors, and even here, we see the chip running under 60°C, and pulling 60.2 W peak, as measured by HWinfo; whereas with CPB enabled, the chip can run as hot as 92.1°C, pulling up to 110 W, pushing clock speeds up to 4.45 GHz.

You can get a 12700K today for about the same price as a 7600X MSRP, match that 7600X high single core and stomp all over the MC scores without OC, basically without trying at all.
Straight from the benchmark thread on CB23 at this site:
If you OC, you get stuff like this 12600K:
But dayum it took me 1 week to configure 5800X, and it looks like u have to configure/tune most of 7xxx too, to achive good expirience, thats sucks about zen3/zen4
I'm not knocking AMD cause Intel has been building mini heaters for while now. But everyone says to just under volt the CPU to get rid of the heat. If you need to do that to keep the heat down then dont buy a $300 CPU. Why buy an expensive CPU if your just going to undervolt and slow down the chip. It's like driving a Ferrari with a governor installed to keep you from speeding.
I have undervolted CPUs in laptops before and it made more sense cause I dont like my chip running at +90C for a sustained gaming session. The CPU will lose long term performance to be under that much heat for extended periods of time. I think it is called electromigration, but I bet someone here knows and will correct me if I'm wrong on the terminology.
Going deeper into the dispatch stalls reveals that the ROB (reorder buffer), load and store queues, and FP registers are the most important factors affecting Cinebench IPC. There are rumours that the ROB size has increased by 25%. AMD has mentioned load/store improvements; these should affect Cinebench as well.
If you buy cpu's based on CB*, CPU Z and GB scores you are doing this very wrong. *for those that actually render however most the people that rant about CB scores are just gamers
People that know what they are going usually buy based on their workflows. Well adults at least.
If the leak is reliable, I cannot even imagine the temps on the 7700X. It may be extremely hard for single CCD Zen 4 SKUs to reach maximum performance with MT loads, due to thermal throttling.
On the other hand, this 6c/12t 7600X scores 10% higher in ST than a max tweaked 5950X, and gets the same score in MT as an 8c/16t Zen 3. So there's definitely progress in IPC.
Your comments ont the 7700x would be valid if that were the stock settings, but pushing at 8 core binned for slighly higher frequency will certainly provide better performance.
My budget Intel build, at a lower frequency (be it only 4.6ghz 100mhz less) seems to have an upper hand.
I mean this 12400F is hardly challenged. And this is the stock cooler. Maybe squeeze 4.8ghz from it even.
