CPU Benchmarks

Comparison of these two CPUs is going to be interesting. Both laptops being tested excel in different ways:

ASUS Zephyrus G14 vs Razer Blade 15

16 GB DDR4-3200
22-22-22 1T
DRAM 16 GB DDR4-2666
19-19-19 2T

The ASUS device has more cores, and by the looks of our testing, actually turbos to a higher frequency, regardless of the sticker on the box. We’ve already shown that AMD’s Zen 2 can have comparable if not better IPC than Intel’s Coffee Lake refresh, so add that to the more cores, should put every test in AMD’s camp.

 

What should benefit Intel here is the on-box TDP, of 45 W, compared to the AMD 35 W. When we fired up our usual program for monitoring Intel frequencies, it showed that there is a hard coded BIOS boost up to 60 W, which we thought should give some extra power. However, when the system was actually set to a workload, the peak turbo power was only 45 W, which the system was able to keep for 10-15 seconds. Then it sat back at 35 W, which makes it in line with AMD. This is odd performance from the Intel CPU, however we assume at this level that Razer has made the decisions in order to fit within the thermal profile of the Blade 15 chassis.

If Intel has a lower frequency, fewer cores, and a lower frequency, all for the same power envelope as AMD, then it looks like a slam dunk for AMD.

It is. These systems are built with productivity in mind, and even with benchmarks that are bursty like PCMark, AMD takes the win.

Civilization 6 AI Test

I also took some time to run the Civ 6 AI benchmarks, which performs 10 turns of a late game and averages the turn time. Intel won this test, but I performed it again with the power unplugged and on battery saver mode in Windows. The results were reversed:

Civilization 6 AI Test Low Power

This led me to do some more tests without power connected. I’ve separated these out into a different page, combining some CPU and some GPU data.

    The C920 is nice unit - next to impossible to find at the moment - bought mine a while back - a C920S - which has the privacy shutter.

    It is most definitely progress, without a doubt.

    Battery life is incredible. I really wish Asus had an option to lock the display to 60Hz if the dGPU was off like you mention Razer does. Or even better lock the display to 60Hz if the dGPU is off *AND* on battery power. The latter of the two seems like the best solution. It's too bad we aren't seeing more OEMs put these in higher end laptops. This along with new Nvidia Max-Q tech seems to be the perfect recipe for thin and light 13-14" laptop designs that the 45w H chips could never quite deliver on.

    Excellent performance!

    Should you expect a performance hit if you were to add another stick with 3200mhz instead? I was planning on adding a 16gb 3200mhz stick in the hopes of running 24gb all in 3200mhz. I'm curious to know if it will even run at the right speed, and whether it will be as fast, or very close to the stock 16gb at 3200.

    i think this was address in the article

    By the look of it, it could, but it maybe won't by default. You would might well have to re-program the module (if you can find a way to do that, it may involve a hardware hack) or else wait in hope for ASUS to offer an update enabling XMP.

    I think there should have been more pushing on the manufacturer of this point, as many are likely to install aftermarket memory sooner or later.

    If the infinite fabric version for Ryzen Mobile 4000 series is newer than the previous one how much will it impact performance?

    I dont know why this and similar processors are not packaged in decent streamlined chassis like Lisa Su is holding to introduce this cpu. Dear ASUS, MSI stop making chassis(s) for drag-queens, most of us are descend corporate employees who dont want to flash/swing their "assets" out and about. Current day programming/cloud/vms/containers demands are making people like me desperate for such processors BUT in decent/sleek/non-intrusive chassis designs and you are holding us back. I understand heat dissipation and other factors may push u for this but it is still not the excuse. Lenovo etc are making mobile workstation which are slimmer and less flashy than asus one above. Take few pages from phone designs like Samsung Note, Xperia Z Ultra.. world has changed .. dont remain stuck in mid-late 2000s. Just phone Lisa Su where she got that chassis.
