  • We've all heard a lot of talk about Intel's Alder Lake processors, but nothing like this.
  •  A Youtuber that specializes in running some intricate benchmark tests sheds more light.
  • The Alder Lake iGPU actually hit 2,378 MHz on some pretty awesome water-cooled setups.
  • As a test result, this is unbelievable, considering that this is a 61% performance increase.

You’ve most likely heard about all the issues and disappointment surrounding Intel’s latest processor, but wait until you get a load of this.

Youtuber SkatterBencher has shown how overclocking Alder Lake’s iGPU could lead to significant performance gains.

And, if you want to talk numbers, know that the GPU hit 2,378 MHz, delivering over 60% higher performance in different workloads.

We can’t lie, Intel’s Alder Lake 12th Gen Desktop CPUs have shown quite impressive performance but there is one surprise element of the new chips that have not been talked about and that’s the integrated graphics or iGPU.

This line of processors comes with the UHD Graphics 770 engine, based on the Xe-LP architecture and 10nm process.

And yes, the Alder Lake GT1 is at the heart of the UHD Graphics 770 solution and features up to 32 Execution Units (EUs).

So, seeing how there are eight ALUs per EU, the UHD Graphics 770 amounts to 256 ALUs in total.

Over 60% performance increase on some water cooled setups

While both Intel-powered chips, Rocket Lake and Alder Lake have no major integrated graphics changes, the Alder Lake chip tends to run 550 MHz faster (900 MHz for Core i9-11900K).

What this basically means is that the Alder Lake iGPUs are already much faster than the 11th Gen Rocket Lake part.

The creator of the video, SkatterBencher, pushed the Intel UHD 770 integrated graphics chip to its limit using a water-cooled setup.

This is an integrated part so it shares power with the main CPU itself but regardless, you can tune the iGPU on its own using the motherboard BIOS or from the XTU app that Intel has produced.

Also, in order to achieve the final result, he increased the VccGT voltage to 1.375V, which allowed him to raise the BCLK to 115 MHz.

The UHD Graphics 770 engine has a 300 MHz base clock, but the boost clock varies from one Alder Lake chip to another.

To better explain, the Core i5-12600K and Core i7-12700K have iGPUs that can boost to 1,450 MHz and 1,500 MHz, respectively, while the one for the Core i9-12900K tops out at 1,550 MHz.

Thus, SkatterBencher overclocked the iGPU for his Core i9-12900K to an impressive 2,378 MHz, resulting in a 53% increase in boost clock speed.

You might be glad to know that the iGPU achieved a 49% higher performance in Counter-Strike: Global Offensive, increasing frame rates from 52.79 FPS to 78.49 FPS.

A 41% increase was recorded in Final Fantasy XV, but, the iGPU could not hit the 30 FPS target. Note that the YouTuber used the standard preset at 1080p resolution.

Keep in mind that, in a real-world workload, such as HandBrake, the performance increase was only 15%.

Unfortunately, SkatterBencher has proven that the iGPU doesn’t perform well outside of synthetic benchmarks, even with a substantial overclock.

Did you know that this line of processors is actually more efficient on Windows 11 than it is on its predecessor?
