Hello everyone. I just finished a PC build and fired up Minecraft for the first and it is pretty much unplayable. it stutters and there are screen tears when you look around and the game will stutter and freeze for a second or two when you try to move. And I'm not talking frame rate drops, I mean the game stops doing anything.

Th PC build is:

Intel Pentium G4400 3.3GHz Dual-Core Processor

ASRock H110M-HDS Micro ATX LGA1151 Motherboard

G.Skill Aegis 8GB (1 x 8GB) DDR4-2133 Memory

Radeon HD 6500

So far I have tried:

lowering in game settings like draw distance to 2 chunks, clouds, shadows, gradient lighting off, graphics set to fast and so on.

turned VBOs on and off while trying various settings.

I have allocated 4 gb of ram to Minecraft.

made sure java 64 bit is installed and up to date.

Updated my video card drivers.

The server I am playing on is hosted from my other, older PC, which runs with no issues. The server is rather large at this point but there were no other players and after allowing time for it to load, the game still played poorly. I also played single player with the same results.

Anyone with another idea please, I am out of ideas and beginning to regret building a PC if it cannot handle this.
 
Solution
You are running a low end system, and the game of an even slower system? There is pretty much the issue.

If Java and drivers are updated, only thing left is the speed of your computers.

Your system is fine for running Minecraft. Maybe I can help address some of your questions.

64 bit Java should be using 2GB of RAM especially if you are running single channel RAM (1 stick)
Since Java Garbage Collection (GC) spends some time to clean up RAM, that explains your frequent lag spikes every now and then.

Use less RAM for smaller lag spike and GC.
I suggest the JVM arguments.
-server -Xmx1G -Xms1G -Xmn256M

Furthermore HD 6500 is a very old GPU. You should upgrade to something like a RX 460 or GTX 1050. I suggest to Increase your FPS you should remove the graphics card and run on your Intel HD graphics which is newer.

Enjoy your PC gaming.
-Use 1GB RAM
-Remove the HD 6500
