Please note this review is a work in progress, and there will be an ongoing updates as I get new understanding. I've had it for about a week when this thread was started and there is still much I want to try tinkering with. I can try to answer any questions about its functioning. Further information can be found in our Comparison of Mobile Graphics Cards and the corresponding Benchmark List. So for my laptop I'm looking at around 11 to 15% increase from Optimus tech. However, I wonder if there is a software element to this that skews my results. I was also looking at the CPU, iGPU, dGPU powers in both cases. It looked like the dGPU was enabled in both cases, reporting >10W. The dGPU did not entirely shut off. If it did, that could result in more like a ball park 2x battery life extension. Running the FFXIV Stormblood benchmark, this shows 65W peak power on the CPU peaking at 84C. The GPU similarly logged peaks of 120W and 74C. Average 127 fps, and for my personal gameplay that is excessive. I'll have to look for a cap at some point where even around 80fps is plenty, which should reduce both power usage thus heating. Nvidia’s latest laptop graphics chips run at different power levels to deliver varying levels of performance and efficiency. The GeForce RTX 3070 inside the Legion runs at 130W, which is about as high as this chip can go. Elsewhere, it’s got the usual 8GB of memory and 5120 stream processors.

Case — Legion With A Dash Of ThinkBook

No coil whine that I can hear. There is a whine that seems to be from the fans. I only noticed it yesterday so I wonder why. I made two changes in a short time so it could be either the firmware update or me opening up the base shifted something. Maybe it was always there and I didn't notice. Now I've noticed I'm fixated on it. When the laptop is idle I wish it was a quieter, but when the fans are running under load that is normal noise.

I also ran the in-game benchmark of Rainbow Six: Siege using the Low and Ultra presets (both at 100% render resolution) at 1080p. The Legion 5 Pro averaged 316fps in Low and 262fps in Ultra, which should raise the eyebrows of esports athletes looking for a capable gaming laptop at an approachable price. This would keep the 165HZ screen on offer here well filled with frames. Battery Rundown Test The other thing to note is just how much better Quiet mode is on the CPU temps and the noise level. It’s so much quieter that would probably play games in this mode much of the time, if I used this laptop daily. For some games, including Horizon Zero Dawn, shifting to Quiet mode doesn’t cripple performance, but there is a noticeable impact on other titles, so you’ll have to test out the profiles yourself. We're pleased to note that there isn't a whole lot of bloat on the Lenovo Legion 5 Pro (other than perennial offender McAfee), so there won't be a whole lot here that you're going to need to uninstall.Paired with this hardware is 16GB of RAM, which comes in 2 modules of 8GB and is replaceable. If you’re wanting to get the most out of your PC, you’re probably going to want to replace this RAM though, as it’s the same single ranked RAM I saw in the Legion 5 and Legion 5 Pro. We’ll get into the performance differences shortly. W (~6 h 21 min of use)– 1080p Youtube fullscreen in Chrome, Better Battery Mode, screen at 70%, Wi-Fi ON, screen set to 60Hz;
