Overclocking Potential of New CPUs: Benchmarks

Hey everyone,

With the recent release of the new Zen 5 and Raptor Lake Refresh CPUs, I've been seeing a lot of hype about their overclocking potential. I wanted to create a thread to consolidate benchmark results and discuss real-world overclocking performance.

I've been testing the new Intel Core i9-14900K and the AMD Ryzen 9 7950X3D with my custom loop cooling setup. So far, I've managed to push the 14900K to a stable 6.2 GHz all-core on the P-cores with ~1.45V, though temperatures under heavy load (like Prime95) can still hit 90°C. Cinebench R23 scores are sitting around 42000 multi-core and 2200 single-core.

For the 7950X3D, I've focused on undervolting and slight frequency bumps on the non-3D V-Cache cores. I've achieved a stable PBO limit of ~5.3 GHz on the performance cores with a negative offset of -25mV. Cinebench R23 scores are around 38000 multi-core and 2000 single-core. The 3D V-Cache cores remain untouched for gaming benefits.

Here are some key benchmarks I've run:

• Cinebench R23:
• i9-14900K (6.2 GHz OC): MC 42000 / SC 2200
• R9 7950X3D (5.3 GHz OC): MC 38000 / SC 2000
• 3DMark Time Spy:
• i9-14900K (6.2 GHz OC): CPU Score ~18500
• R9 7950X3D (5.3 GHz OC): CPU Score ~17800
• Gaming Benchmarks (Cyberpunk 2077 @ 1080p Ultra):
• i9-14900K (6.2 GHz OC): Avg FPS ~210
• R9 7950X3D (5.3 GHz OC): Avg FPS ~205

It's interesting to see how the architectures differ in their overclocking headroom. The Intel chip definitely has raw frequency potential, but the power draw and heat are significant. The AMD chip's efficiency, especially with undervolting, is impressive, although the 3D V-Cache configuration presents its own set of tuning challenges.

// Example system specs
CPU: Intel Core i9-14900K / AMD Ryzen 9 7950X3D
Cooling: Custom EKWB Loop (360mm Radiator)
Motherboard: ASUS ROG Maximus Z790 Hero / Gigabyte X670E AORUS Master
RAM: 64GB DDR5 7200MHz CL34
GPU: NVIDIA RTX 4090 Founders Edition
PSU: Corsair HX1200i

Great thread, CPU_Enthusiast! I've been playing around with the i7-14700K. It's not the top-tier, but it's a sweet spot for me. I managed to get all cores to a stable 5.8 GHz with ~1.38V. Temps are manageable with a good AIO, topping out around 80-85°C in Cinebench.

Cinebench R23 scores are around 34000 multi and 2150 single. The extra E-cores on the 14700K compared to the 13700K are really noticeable in multi-threaded tasks.

My system:

CPU: Intel Core i7-14700K
Cooling: Arctic Liquid Freezer II 360
Motherboard: MSI MPG Z790 Carbon WIFI
RAM: 32GB DDR5 6600MHz CL32
GPU: RTX 4080

I haven't pushed it much further as I'm not comfortable going much over 1.4V for daily use. Has anyone tried pushing the 14700K past 6.0 GHz?

Interesting results! On the AMD side, I'm rocking the Ryzen 9 7900X, not the X3D. I've found that for this chip, leveraging the built-in Eco-Mode with a custom PPT limit is more effective for thermals and sustained performance than raw manual OC. I'm running it at 120W PPT, which caps it around 4.8 GHz all-core, but temperatures stay below 70°C even under full load.

Cinebench R23: MC 29000, SC 1950. It's a bit lower than manual OC, but the quiet operation and low temps are worth it for me. My system is a bit older with a 240mm AIO.

Anyone else having success with Eco-Mode or similar power-limiting strategies on their Ryzen 7000 series chips?

I'm sticking with the Ryzen 5 7600X. While not "high-end" by some definitions, it's perfect for my needs. I haven't done any aggressive manual overclocking, just enabled PBO with Curve Optimizer and set a slight negative offset of -15 on all cores. It boosts to around 5.2 GHz on a couple of cores when gaming.

Cinebench R23 scores are ~17500 multi and ~1980 single. My temps with a Noctua NH-D15 are excellent, rarely going above 60°C. For gaming, I'm getting very similar performance to the i5-13600K in most titles I play, and it's much more power efficient.

It's good to see the big boys pushing limits, but sometimes a well-tuned mid-range chip is the way to go!
