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.

You guessed wrong, but considering your education level that should be expectedKorguz - Saturday, August 3, 2019 - link
i did ?? sure seems like you only want quad cores still... my guess, yours is maybe grade 10.AntonErtl - Friday, August 2, 2019 - link
I am guessing that SPEC CPU2017 Rate-1 means one copy of the benchmark, so it also gives us single-thread performance (and that explains why the power limit differences do not play a bigger role). Right?One thing that I find remarkable about the recent AMD and Intel launches is that Intel follows the pattern (already seen with Broadwell) of starting a new process with a low clock, and therefore with mobile products and then servers. If they follow their earlier pattern, we will see higher-clocked stuff on 10nm in the future.
By contrast, AMD (and the smartphone SoC vendors) manage to get the same or better clock rates with the newer process as with the older ones.
From what I hear, Intel is very much into hand-tuning their CPUs (that's why backporting Ice Lake to 14nm would be very expensive in terms of both labor and time-to-market), while AMD and the smartphone SoC vendors rely on more automatic tools. What is interesting is that AMD managed to get within a few % of clock rate of a highly tuned Intel chip (with several years of tuning both the process and the layout of the chip) with this more automatic approach, while having a similar IPC.
Intel has been working on Ice Lake and 10nm for a while, and still suffer from a clock rate deficit compared to Whiskey Lake (but in a way, 10nm is just becoming usefully online now, so maybe we should start the clock now). The fact that they have increased the TDP of the Y SKUs and decreased the base clock of the 15W SKUs (from 1.9GHz for the 8665U to 1.3GHz for the 1065G7) indicates that they still have problems being competitive wrt power consumption under load with Whiskey Lake. It will be interesting to see the final products (and compare them to Whiskey Lake and Picasso products with similar power delivery and cooling).

AMD pushes their overvolted chips to the very limit. Intel doesn’t have to.Korguz - Friday, August 2, 2019 - link
" Intel doesn’t have to. " um.. i guess you havent seen the articles about how much intels cpus really use then. 95 watts, up to 200 watts in realityPhynaz - Saturday, August 3, 2019 - link
Wow, you’re really, really dumb. Do you get state aid?Korguz - Saturday, August 3, 2019 - link
oh how so ?? AT even posted a write up on this, obviously, you havent read it. so you are the one that needs aid, as you are the dumb one here....Alexvrb - Monday, August 5, 2019 - link
Reading isn't Phynaz' strong suit. However when you state a fact he can't counter, he immediately switches to low brow personal attacks - those are really more his speed.mobutu - Friday, August 2, 2019 - link
It doesn't mattter (for me), this time I'll buy AMD.HStewart - Friday, August 2, 2019 - link
Then why comment if it doesn't matter to you.
