I’ve already reviewed the i5 8250U 8GB model of the Mi Notebook Pro, the RAM limit of 8GB (nonupgradeable) made me sell it and buy this model. The i5 model came out a good month before the most powerful version which is now out powered by an Intel Core i7 8550U quad-core CPU, the Nvidia MX150 GPU remains & 16GB of RAM. The only change to the model is the faster CPU and double the RAM which is 16GB of DDR4 2400Mhz RAM. My Mi Notebook i7 8550U review is below:
This video only covers the new chipset, the design, battery life, build & design and speakers is all covered in the full Mi Notebook Pro review.
Sadly no fix yet it seems for the SSD slots. Both run at PCIe x 2 mode and not x 4 so we can get the full speed of the NVMe Samsung PM961 SSD this laptop comes with. Performance of the i7 8550U is great, with 1 megabytes of cache and 600Mhz higher max turbo more than the i5 8250U you do see the difference in synthetic benchmarks. And like the i5 8250U model, the power limit is what holds back this great CPU.
In my testing with Intel XTU application, I was able to get the i7 8550U to perform close to a desktop i7 4770k CPU in Cinebench R15. A remarkable result considering this is an ultrabook not a big desktop, but not really too practical for extended periods. As a 35W TDP limit (25W over the stock 15W limit) caused thermals to peak up to 91 degrees when encoding 4k video. So the maximum you can really safely use is a 30W power limit with Intel’s Xtreme Tuning Utility. But don’t forget to undervolt it -0.095 volts to this helps keep the temperatures down.
But under the stock power limit and GPU clocks, thermals are great. Temps taxes both the GPU and CPU are perfectly acceptable. The CPU staying under 80 degrees C and the GPU under 70 degrees C. And if you’re wondering does the faster CPU mean it will give more FPS in games? Yes, but a minor difference. If gaming is important to you, you might be better off with something with at least a Nvidia 1050 GPU. But the MX150 can at least play modern 2017 titles at 1080p as long as you tweak visuals or go with the lowest setting possible. And you also want to overclock the GPU with a +1000Mhz clock on the MX150’s memory clock and +200 Mhz on the core clock. This can really help the GPU produces a nice 14-20% or more frames per second making games smoother.
Battery life on this i7 model is a little less as expected from the 600Mhz faster turbo and base clocks. But only around a 5-10% difference. Battery Bar Pro also reports a slightly larger battery at 62 WH and not 60Wh? I wonder if it’s just a glitch or Xiaomi did use a slightly larger battery?
