System Results (15W)

When testing a laptop system, there are various angles to consider on how to test: either user experience benchmarks, that are mostly single threaded and give a good boost to how systems implement a deal of turbo, or sustained benchmarks that test how the system performs when you push it. Intel has gone out of its way to emphasise the former for the next generation of mobile CPUs: they would prefer that reviewers stick to very user experience-like tests, rather than say, rendering programs. The problem there is that outside a number of canned benchmarks, it can be difficult. Users, and especially creators, that typically spend a lot on a premium device, might actually be doing sustained benchmarks.

Given the time that we had to test, we were actually limited in what we could arrange.

Application Loading (GIMP 2.10.4)

3DPM v2.1 (non-AVX)

3DPM v2.1 (AVX2 / AVX-512)

On AVX-512, the Ice Lake part destroys the competition.

Blender 2.79b (cpu-bmw27)

POV-Ray 3.7.1

CineBench R20 ST

CineBench R20 MT

7-zip 1805 Combined

WinRAR 5.60b3

AES Throughput (minus AES instructions)

These last two tests are typically our more memory sensitive tests, and the LPDDR4X-3733 really does win out over the LPDDR3-2133 in the other systems.

    It's like a long running Intel advertisement ...... Reply

    How so? Reply

    Probably because you provided objective measurements instead of long winded conjecture. Reply

    "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. Reply

    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.

    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. Reply

    "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.

    I'm encouraging the behaviour. I've been on at Intel to do something like this for a while. I'm giving credit where credit is due. As always with events like this companies like Intel have PR saying they want to do something, and the legal side of the equation resisting. If we get more opportunities like this in the future, it helps us provide a richer content base in advance of a product launch - people get to prepare in case they're in the mood for a purchase.

    Also, tell me if you say the same things on our Qualcomm QRD testing. Please.

    You are just trying to get an edge over other sites but you are just being played.

    It's the same BS with Qualcomm and their mmWave BS that has been spread by sites like this. Now 5G is just sub-6 and the only important part is massive MIMO
