Minecraft Server – STEM

I use this a lot for teaching STEM education to younger future programmers to be. The creators of mincraft had a goal of teaching and enabling, exploring  programming especially to kids, as well as having fun playing Minecraft.

Alienware 17 R5 – Notes

General Notes on the Dell Alienware 17 R5:

10-20-18
Base unit came with GTX1060 6gb, M.2 Sandisk 2280 128Gb, 1Tb 2.5″ Hard drive…

Quick comparison to an older unit, no dual HDD option, no DVD/Burner drive, less USB drive slots, no SD card slot, but lots of newer VR friendly options, faster CPU and faster/more current GPU

Benchmark results, see this link,

M.2 upgrade device that worked for me – in Slot 2:
WD Black M.2 2280 500Gb PCIe nvme [$129]
Note – Sandisk V-Nand will NOT work for Slot 2
Slot 3 is M.2 2240

Alienware 17 R5 Benchmark

Using the software Superposition Benchmark – click here to download.

For CineBench – click here to download the free benchmark software’

Compared with my custom main workstation PC, using a dual card 8Gb GTX1080 and 4Gb GTX970

With same workstation, just with the GTX1080 8Gb card

From above, it seems my main PC as l have researched is limited a bit when a 4Gb GTX970 is in it.

Also note the processor is much older, compared to that in my new laptop below.

Below is the Alienware 17 R5 Results

Catzilla Benchmark Results

Discovered this free but very good Benchmark software – Catzilla – Click here for the download website.

Here are my various PC results.

A17 laptop – GTX860M  [4 years old]

 

PC with 2xGTX560Ti   [recent build]

PC with GTX1080 8G + GTX970 4G  [ 5 year old PC , i7 2600K at 3.4Ghz 32Gb ram with new Nvidia cards]

 

Blender Open Data

I’ve used several benchmark software to compare computer hardware especially nvidia GPU cards used for cuda programming.  One good free benchmark software is Maxon CineBench    , another is Unigine Haven

 

Here are surprising results generated from the new Blender Benchmark under its Blender Open data website program.

Quick summary/my findings:

  • less render time running Linux [LinumMint] than under Windows 10 [all things turned off], same hardware
  • SSD’s help

Linux run: Workstation with GTX1080 8Gb, GTX970 4Gb, 32Gb RAM, Quad core Intel processor. No SSD

Same hardware as above but run under Windows 10

Ran on same hardware, only using the GTX1080 8Gb , under Linuxmint – impressive resuly showing in my view and from cuda/nvidia research l did that the 4Gb of the 2nd graphics card limits the performance.
