One point I need to address. The AMD issue. The A series processors were tailored for laptops of the thin and light format. The chip also has a Radeon GPU internal to it, which saved space. However, that also increased the thermal issues (CPU and GPU on the same die. A good analogy would be trying to cool you entire modern desktop with only an 80mm power supply fan), so they throttled both functions to avoid meltdown. Even 65 watts of heat dissipation can roast a transistor junction if there isn't sufficent cooling.

The other point of bottlenecking was system memory. The combined CPU/GPU scheme required shared memory, so you typically lost at least a gigabyte to the video function at a minimum. Then you also have the fact that video memory is limited to system ram speeds. Current VRAM is DDR-5/6, depending on the cost of the card, where laptop memory is DDR-3/4, depending on what you spent on it. So video is going to be slower on a laptop than on a desktop rig. In a desktop setting an A-10 performs very well, within the limitations of its age. You can compensate for a lot of the issues then by using high capacity cooling, top end sys ram to get the best video performance out of the hardware, and with a non-lap motherboard, you should have a larger pool of memory to install, letting you assign X-gigabytes to video and the rest as system.

As far as laptops go, the issues to look for are 1). OpenGL. You can not upgrade 99% of available laptops, so the video you buy is the video you are stuck with. If it only supports OpenGL 2.3, you are out of luck with any software that requires 3.0 or higher. A program using 2.3 will do just fine on 3.0+ hardware, but a 3.1 program put on 2.3 capable hardware is likely to be a pain. The whole number upgrades of OpenGL usually involve code that talks to buffers and functions that simply do not exist in earlier versions, so anything that depends on that 3.0 standard might work, might, not, or might crash the whole magilla. No matter what Redmond thinks, OpenGL is still the standard in non gaming graphics.

2. Memory. Very few laptops have more than two memory slots. They also do not use the dimm format that desktops use. Most of the modules are simm, They are shorter, and taller, meant to be slid into a socket at an angle. Where you can get into trouble there is in cost. Outside of a handful of sizes, laptop memory quickly becomes a specialty item, with a price to match. Some companies try and stay with standards; others customize it and charge out the wazhoo for their 'custom' parts. Caveat Emptor.

3. Hard drive. More and more laptops are shifting to SSDs now that prices have fallen. This is good for portability and weight. However, be aware that even now, you are at the mercy of physics. There is a condition in semiconductor storage known as 'atomicity'. In simple terms, every time an SSD transistor switches states in reading or writing, there is atomic level damage done. One or more atoms are dislodged from the insulating matrix, weakening the semiconductor's junction. When enough atoms are 'broken, the junction fails and that bit is dead. Which killed the drive completely. Since they were introduced, they have changed how they made the substrates, adding many more cycle times to the average lifespan. They also introduced software schemes like SMART (and a couple others I can't think of atm) to prewrite a byte, and if it fails, mark it as bad and move to the next byte. But be it SSD, flash drive, usb stick, whatever, if it is solid state storage, it has a limited lifespan. So plan to back up often, and there is no 'too much' as to layers of back up. Currently I have all of my Poser runtimes backed up on 2 external HHD, and plan to put together a Terabyte SSD as a 3rd backup. It doesn't have to be elaborate; pick up a Seagate 5T USB pocket drive, back up your perishables, unplug it and place it in a static bag, then into a cushioned bag to be placed into a fire safe or somewhere offsite, just in case. Modern SSD's have an average mean time between failures of around 2.5 million hours. Note the word average. That gives roughly the 5 year daily usage warranty period most drives have (surprise surprise). But one can fail any time, just as you can buy a smart phone and it dies on you the next week. They also have multiple form factors you need to be aware of. Laptops tend to use the M.2 format, which is basically a printed circuit card with one end that has connector tabs. That has 3 sizes 2260, 2280, and 22110. Each one is longer than the one to the left, and the 22110 has two index notches on the connector. The next is the 2.5" rectangular format that mimics the small hard drives they use in laptops. The M.2's are likely to be buried in the laptop so deeply that the average user can't access them. The companies that use the 2.5" format tend to keep their old cases, which should have a panel you can remove to access the drive.

4. Display. Whatever you do, don't get a small screen laptop. The text on Poser will be next to unreadable, and we currently don't have the option of changing it or enlarging it. Those who have poor eyesight will suffer eyestrain and headaches, and the ones with good sight will go along until one day they notice they can't see clearly. If you have no choice, make sure that the laptop has an external monitor port. It should be HDMI. Then you can simply plug in any size monitor you want at home.
