Surprisingly, clock speed efficiency of TGL-45 under CPU heavy load is similar to Ryzen. Looking at many reviews of TGL-45 laptops, I believe it is not heatsink related since Legion 2021 models use a decent stock paste (Honeywell TPM7950), more to the silicon design itself. Note that in TGL-45 CPUs, uneven core temp is normal, even at idle it will have about 5C difference. There is uneven CPU core temp of ~10-15C while under load (odd number cores - 1,3,5,7 have higher temp). There is a special tweaking section in the following of this review. Quiet mode : PL1 25W, PL2 45W, GPU 80W (no DB)īalance/auto mode : PL1 70W, PL2 92W, GPU 80-95W Max fan noise is around 54-56dBA with max fan mod, not annoying due to low pitch but still quite loud Laptop is lifted, ~1.5cm space at bottom for airflow There are 4 exhaust vents, besides intakes from bottom the keyboard also has holes for more ventilation. The cooling solution has 4 heatpipes: 1 shared on CPU&GPU, 2 individual pipes on CPU and GPU, and 1 at the backside of the heatsink for VRAM cooling. Not to mention that the speakers are front facing also in Y530. Even after some manual tweaks, it's still sound a bit worse than the Dolby software powered Y530. Luckily there are a number of options that can be adjusted there. These are the settings I use:Ĭompared to my Y530, I would say the audio is a slight downgrade. I have to manually tweak some settings in Nahimic software. I suggest sitting closer to the laptop so that the audio from speakers will have a more direct path to your ears. If you are sitting far from the laptop, the audio experience is mediocre. The 2 down firing speakers are located at the sides. The response time is also slightly lower. Compared to my Y530 with 144Hz 72% panel, I can feel the colours are slightly more accurate and richer, while contrast is much better. Unlike Legion 5 Pro or 7, it is not colour calibrated with X-Rite (still looks decent out of the box) and does not have a 60Hz switch (although you can create custom profiles). Some might argue that it has a slight yellow tint, but I prefer it. Ghosting is minimal, and there is an overdrive option in Vantage (although might introduce some inverse ghosting). The 15.6 inch 165Hz FHD IPS display from BOE (BOE0998) has great colours, brightness and contrast. They should put the clickpad at the middle of the keyboard layout excluding the numpad (eg align more to right), but this is not a big deal.Ĭompared to my Y530, the keyboard is slightly better but for touchpad/clickpad, I think both are fine. The clickpad is quite big, but slightly aligned to the left which is a bit unnecessary IMO. The L/R clicks are shallow and a bit mushy, kinda like what u expect from an Ideapad. However, if you use it for a long period of time, you might have uncomfortable fingers due to the friction on plastic surface vs glass. The clickpad has good accuracy and smooth gliding. I am very impressed on the build quality overall. The 5i also feels more solid when holding in hand, making the Y530 feels cheap - you can feel the thinness of the chassis layer in Y530. I think you don't have to worry about the soft touch plastic surface getting dirty every day or might tear off after a long period of usage. The plastic material used doesn’t feel cheap at all, in fact there is a slight metallic feel on the C cover.Ĭompared to my old Y530, the material used has improved. The hinge is smooth and well calibrated, no noticeable wobbling when shaking the laptop. The lid can be opened with one hand, the maximum angle is 180 degrees. Since it's still a plastic lid, there is some flex when twisting the lid, but nothing concerning. The same can be said when force is applied on the middle of the lid cover. The bottom chassis (keyboard deck/C cover) has little to no flex when force is applied on it. Despite that, build quality is surprisingly good. The laptop chassis is mainly made from ABS plastic.
