Leaked Intel Core Ultra 7 356H Benchmark Scores Reveal Middling Gains

Intel’s Core Ultra 356H is an upcoming 16-core (4 P-cores, 12 E-cores) mobile Panther Lake CPU. Although official review embargoes for the rest of Intel’s Panther Lake CPUs are said to be right around the corner, supposed performance benchmarks for Intel’s latest have already started to leak, with Cinebench R23 and 3DMark Steel Nomad Light results coming by way of @realVictor_M on X. The results indicate strong multicore performance but stagnant single-core scores compared to Intel’s last-generation chips. The iGPU is also notably slower, since the Arc 140V iGPU in the outgoing Core Ultra 7 255H has significantly more cores than the new Intel Graphics 4 Xe3 iGPU in the Panther Lake chip.

According to the leaker, whose results are so far unverified, the Core Ultra 7 356H scored 2013 points in the Cinebench R23 single-core benchmark and 20,721 points in the Cinebench R23 multicore test. For reference, this is slightly ahead of the outgoing Core Ultra 7 255H, which features two more P-cores and two fewer E-cores and averages around 18,679 points in the Cinebench R23 multicore benchmark. Single-core scores, for their part, are about dead even, with the 255H averaging around 2060 points in the R23 single-core benchmark. In the 3DMark Steel Nomad Light test, the Panther Lake iGPU scored 2,110 points. By comparison, its predecessor’s average score in the same benchmark ranges between 3,279 and 3,532 points, depending on whether the benchmark is running in DX12 or Vulkan mode. The upcoming laptop CPUs will have to contend with AMD’s new Ryzen AI 400 APUs, which have already started showing up in laptops and have shown to perform admirably in comparison with current-gen Intel CPUs.
