Old computers vs new ones

Post by etxbkst » Fri Apr 24, 2015 6:21 pm

I'm running a Lenovo Thinkpad Edge from 2010 or 11, Windows 7 with a first gen i5, 4GB RAM, 128GB SSD. It works for lots of stuff, but anything like calculating complex tool paths bogs it the heck down. So, I'm thinking of upgrading. Ideally I'd get a MacBook since I use a Mac for my full time job, but I know a lot of this software is Windows or works better on Windows. My question is, how does Windows 8 (soon to be 10) play with our various software? And how would something like a current gen Pentium stack up to an old i5? I was looking at this: http://www.bestbuy.com/site/lenovo-yoga ... Id=3297045, alternatively, I was looking at the i5 Surface Pro 3 with 128GB SSD. I'd love to stay under 500 if possible.

That Lenovo (or a similar model) has been getting rave reviews over on http://forum.tabletpcreview.com/

I ran a Windows 8 tablet for a while, and applications seemed to work fine and install easily --- still debating about replacing it w/ a Toshiba Encore 2 Write 10.

Is there a reason you're not considering a Surface 3 (not Pro model)? It's just under your price point (until one adds accessories) --- not an option for me since I want GPS.

I didn't realize there was a non Pro version that wasn't RT?

It's a new (and confusing) development:

I played with the new Surface 3 at a Microsoft store last weekend. I was thinking about replacing my iPad 2 with something more useful. It's a slick little machine but the processor is just not going to be fast enough for this use. The new Atom is better but still probably slower than your old i5.

I used Dellrefurbished.com to pick up an older M4600 workstation and a dedicated desktop for my Shapeoko for less than the Surface 3 with accessories and they both can do heavy 3D CAD.

Disappointing that the Atom is slower than my old i5. I just tried to do a 12x18 image in bmp2cnc and it choked, partially due to memory. I guess maybe I'll try upping the RAM it its max of 8GB as a stopgap until I find something else. I'd totally go the workstation route, except that I already have a Pi driving the Arduino/Shield, so I don't want to limit my purchase to just Shapeoko stuff.

Update: I bought the new Surface 3 just for everyday use. It is fantastic! For cad/3d work I am sticking with my laptop for now, although I did get a Toshiba 2-in1 laptop with a Pentium M on clearance at Radioshack for a couple hundred. My intention is to eventually transition over to that.

You don't need a lot of CPU horsepower to send gcode or send simple toolpaths. Complicated ones, it's nice to have a beefier CPU, but an atom CPU (or anything with over about a 500 as a single-core score in Geekbench) should work just fine.

That said, for design work, I'd definitely want something faster.

I got an old dual core windows 7 HP desktop for $50 (4GB ram, 160GB hard drive) plus another $30 for a 17 inch monitor from Craigslist. I did the free upgrade to windows 10.
Its not a speed demon, but its more than adequate to run Carbide connect. I do any design work on a new quad-core in my office and save the files to one drive or dropbox, then I just Use Carbide connect on the old computer connected to the SO3 to load the files from the web storage. I agree with dave, just about any old PC will work fine.
