Synthetic and Legacy Results (15W)
The realm of synthetic testing is a tricky one, given that there are plenty of benchmarks in the wild that provide a number, but aren’t actually based on real workloads, or are very limited in what they actually test. The issue here is that this software tries to emulate real-world, but it isn’t immersed in the harnesses or matrix of what a user might actually experience. For that reason, we only tend to use these benchmarks based on reader requests.
Legacy benchmarks are included for similar reasons, but can help to get a historical perspective.

It's like a long running Intel advertisement ......Ian Cutress - Thursday, August 1, 2019 - link
How so?jordanclock - Thursday, August 1, 2019 - link
Probably because you provided objective measurements instead of long winded conjecture.peevee - Friday, August 2, 2019 - link
"As for Ice Lake itself, our results lean towards Ice Lake outperforming Whiskey Lake, if only by a small margin."A laptop allowing more than 50W on a U chip and with cooler always running is certainly not representative of the real world performance a user would get from real systems. If Whiskey Lake results were obtained on a real system, then the results are not comparable enough that Ice Lake can actually be slower, especially in real world loads (note the performance on x264 and POV-Ray essentially has not changed).
But at least iGPU has improved nicely.

They have dedicated pages to 15w and 25w results. Not sure what you're on about about 'allowing more than 50W...' when they power limited the chip for specific-scenario benchmark results.Spunjji - Monday, August 5, 2019 - link
You may want to re-read that Power Results section - put simply, peevee's point still stands and your response is mistaken. At the 25W limit, the CPU spent more than 20 seconds operating between 50W and 35W before it finally dropped down. It's unlikely that the Coffee / Whiskey devices they tested allowed that sort of behaviour, as without a continuous 100% fan speed the thermals would have spiked and lowered the power limit far sooner. Even with the "power limits" you're talking about in place, the chip still boosts like that, so their benchmark results incorporate that behaviour. for any other company I might feel generously inclined, but Intel have already pulled a fast one multiple times by releasing CPUs that have nominally higher specifications but never reach their performance potential in shipping designs due to thermal constraints.Gondalf - Wednesday, January 8, 2020 - link
Spec suite (the reference) is a pretty loooong bench so the cpu stay at 15W all the time without your 50W. Your comment say a lot about you.yeeeeman - Wednesday, June 17, 2020 - link
Also, we not comparing power efficiency here but rather IPC of each core. And the bottom line is that Sunny Cove core has 5-10% better IPC than Zen 2.CSMR - Sunday, August 4, 2019 - link
There is no evidence that the iGPU has improved. We'd need a comparison against Iris Plus 655 to confirm that. We only know EUs have increased (64 vs 48) but EDRAM was removed.brakdoo - Thursday, August 1, 2019 - link
"First of all, I must say that Intel offering us to test a reference system in advance of a launch is a very good thing indeed"You are being played once again as a marketing tool for the Ice Lake launch. Don't tell me you don't see that.
