It's time for the PCPer Mailbag, our weekly show where Ryan and the team answer your questions about the tech industry, the latest and greatest GPUs, the process of running a tech review website, and more!
This week, Ryan's back from Hawaii to tackle these topics:
00:26 – Ryzen laptop reviews?
02:45 – Component order in custom water cooling loop?
04:46 – NVIDIA variable refresh rate in HDMI 2.1?
07:19 – Next-gen VR headset resolution?
09:15 – Worth it to by a 6950X now?
11:23 – Windows on ARM battery life?
14:12 – Reverse hyper-threading?
16:03 – What is deep learning?
18:47 – Best SSD for storage server cache?
20:54 – Ryan's daughter a future gamer?

Wait for the ACER laptop with the Ryzen 7 2700U and Really why can’t ACER get some samples of those out for review!
It’s going to be a while before enough AMD Based laptop SKUs are available to properly judge the AMD Raven Ridger APU SKUs, as that HP SKU may not have the best featre/OEM provided features to let AMD’s APUs.
I personally want to see more Blender testing including not only Blender Cycles rendering but some 3D models with large poloygon counts loaded into Blender’s 3D editor mode UI to see how high the model’s polygon counts can go before the Laptop/Laptop’s GPU performance causes the Blender 3d’s edit mode UI to degrade. I spend most of my time creating/editing 3D models in edit mode and Blender 3D can really tax a laptop’s graphics/CPU if the model/scene gets into the multi-million polygon count range.
P.S. Intel acguired Soft Machines(The Reverse SMT/HT folks)so maybe we will see!

Can under powered PSU damage
Can under powered PSU damage your computer or itself? What if system’s power requirement is 300 watt and power supply used is rated for 210 watt.

Any hints yet to actually being able to buy a
true,full HDR10, Dolby Vision,Freesync 2, 4K monitor?
Not a tv.
I know it won’t be till next year.

This 2014 video is a good primer for how VISC (Variable Instruction Set Computing) works. You should definitely watch it as you don’t seem to understand this technology exists, and as said above Soft Machines was bought in 2016 by Intel.
The video doesn’t get into the machinations of how Out Of Order works but it obviously can get a higher IPC out of multiple cores than it can out of a SINGLE core even in single-thread computation.
It sounded SILLY to me at first since I thought “why not just multi-thread the code?” however the answer seems to be that a majority of the code is still single-threaded and will be for long enough time still to justify at least doing research into it. Whether we see a consumer product is a different story though as per the video they had a prototype in 2014.
If I understand it correctly this could impact existing GAMES where there is a single core bottleneck. Possibly a game like Starcraft 2 (primarily 2C/2T bottleneck) though even if a VISC CPU is created it may not be a desktop component.
Deep Learning:
As said it’s
Deep Learning:
As said it’s hard to define in a short answer, though I saw a great video on TED talking about how driverless cars would work.
It turns out that creating a driverless car follows the same neural development process that a CHILD follows. Sort of. To dumb it down a lot->
Layer 1: video and other sensor input is processed
Layer 2: Image extrapolation
Layer 3: comparisons are made such as contextual awareness
So for example, the car could take in the raw data then extrapolate the key images are boy, bike, hill etc… then further process that in context to say something like:
“DANGER: boy on a bike may go down the hill and potentially hit this car so I should slow down or brake!!”
(though some sensors are simple such as the proximity sound sensor that can result in immediate braking with no processing)
Children develop similar levels of awareness. We start with nouns like “mama” then add in verbs to indicate action. Later on the brain starts to relate all these elements at a DEEPER LEVEL of understanding.
NVidia works with Tesla motors on this very type of architecture to identify the bottlenecks and is fine-tuning this.
*Teaching cars to drive turns out to be following the same initial steps to teach a self-aware AI. It’s all about recognizing the world, then creating a contextual awareness of the parts in it. The final step is to create SELF awareness.
We MAY be less than ten years from self-aware AI. Scary?
Question for future episode –
Question for future episode – I bought an ioSafe/Synlogy fire-resistant/water-resistant NAS safe. I need to stock it with my own drives. I use it for daily backup and I send weekly backups off-site. My concern is that fire safes are insulated to keep heat out, but that means they also can’t bleed heat efficiently. Given this sub-optimal condition, what 5-6 TB HDD’s manage this condition best?
Question for future episode –
Question for future episode – How expert must one be to attempt Intel CPU delidding using a Rockit Tool or similar device? I can clean off old thermal paste and apply new paste for cooler replacement and I’ve built new cooler loops. But I know that delidding has potential risks of it’s own. Once the CPU is delidded, is the process about the same as prepping for a new cooler install?
Why do you not use your
Why do you not use your standard video production set for the Mailbag episodes? The video production set is great! The Mailbag background is disturbing with its inconsistent lighting, frequent Ken and Alex walk-ins and walk-outs, and random detritus scattered about. Don’t get me wrong, I love the Mailbag episodes, but I’d rather not review a colonoscopy of the PCPER office at the same time. And no, Josh or Jeremy, please don’t offer your own colonscopy as alternative backgrounds!!
