Intel 10nm Ice Lake Benchmarks: 10th Gen Core i7 Performance Explored

Intel 10nm Ice Lake Processors - LAME MT, x265, Y-Cruncher

In our custom LAME MT MP3 encoding test, we convert a large WAV file to the MP3 format, which is a popular, day-to-day use case for many end users, to provide portability and storage of their digital audio content. LAME is an open-source mid to high bit-rate and VBR (variable bit rate) MP3 audio encoder that is used widely around the world in a multitude of third party applications.

In this test, we created our own 223MB WAV file and converted it to the MP3 format using the multi-thread capable LAME MT application in single and multi-thread modes. Processing times are recorded below, listed in seconds. Shorter times equate to better performance.

Audio Conversion and Encoding


This test uses only one or two-threads and won't overwork the processor to the point that it's bumping into power and thermal limitations. As such, the 15W and 25W Core i7-1065G7 configurations perform similarly, and both lead the pack once again.

X265 Benchmark
Video Encoding Test

The multi-threaded HWBOT x265 Benchmark is based on the open source x265 encoder that leverages modern CPU instructions to speed video encoding. We tested the CPUs represented here with the 64-bit encoder using the default 1080p workload.
This video encoding benchmark will leverage all cores / threads and place a sustained load on them for an extended period of time. The 15W Core i7-1065G7 configuration lands smack dab in between Whisky Lake and Ryzen, but all three are evenly matched -- the deltas separating them fall within the margin of error in this test. The 25W Core i7-1065G7, however, makes good use of its additional power and thermal headroom and jumps out into a huge lead.

MT Pi Calculator

Y-Cruncher is a multi-core-capable tool that calculates the value of pi to a specified number of digits. In this case, we ran the tool on all threads and had the application calculate the value of pi to 500 million digits. The values below are the time required to perform the calculation, expressed in seconds. As a result, lower values indicate better performance.

In all fairness, this benchmark was likely limited by the 8GB of memory in the Ice Lake system. Calculating Pi out to 500M digits uses about 5GB of memory, which fit easily into the free space on the 16GB systems, but was riding the edge on 8GB Ice Lake rig. Still, the 25W Core i7-1065G7 config outpaced the Ryzen 7 3700U, but Whiskey Lake finished well out in front.
