👁 RawTherapee benchmark with settings of Total Benchmark Time. Core Ultra X7 358H - MSI Prestige 14 was the fastest.

For creator workloads like RawTherapee RAW photography software also shows how much the performance and power efficiency has improved from Penryn to Panther Lake.

👁 libavif avifenc benchmark with settings of Encoder Speed: 2. Core Ultra X7 358H - MSI Prestige 14 was the fastest.

👁 libavif avifenc benchmark with settings of Encoder Speed: 6, Lossless. Core Ultra X7 358H - MSI Prestige 14 was the fastest.

In applications like AVIF image encoding the newer CPUs with AVX/AVX2 benefit greatly here compared to the older CPUs tested.

👁 Basis Universal benchmark with settings of Settings: ETC1S Level 3. Core Ultra X7 358H - MSI Prestige 14 was the fastest.

👁 Basis Universal benchmark with settings of Settings: UASTC Level 3. Core Ultra X7 358H - MSI Prestige 14 was the fastest.

With the oldest Penryn and Clarksfield ThinkPads tested you could really feel the heat output during these demanding multi-threaded benchmarks but that isn't the case with the more recent Intel laptops.
