What is physical core and logical core? + What better ?
1. physical core is the real core that the cpu has, logical core is how many is how many execution it can perform per core, this is usually called multi-threading. Say if a core doing task only used 70% of its capacity, 30% is left unused, with multithread, you can use what's left to calculate another task.
2. All mattered, the CPU, GPU, Memory, Harddrive. You should concentrate on these 4.
- CPU, the more GHZ and more cores / threads the better. Depending on the task, Gaming favors high GHZ, while productivity task favors more threads.
- GPU, the performance usually scaled up with price, similar priced gpu will most likely perform the same. There are 4 different tiers, Low Cost (under $100 - 30fps), Budget (under $250- 60fps), Midrange ($250-$400-90fps), Highend ($400&up - 120fps), (Frame Per Seconds - in games).
- Memory, 16gb is comfortable now, 8gb is minimum, if you have only 4gb, add another 4. Memory size doesn't make your pc faster, it depends on your memory consumption. Memory is like a work table, bigger table doesn't mean you can work more quickly, depends on how many stuff you working on it.
- Harddisk, get a Solid State Disk, is much faster than regular spinning harddrive. But regular hdd got more space for much cheaper. Its best to combine the best of the 2, usually people use SSD for their C (windows) drive and a big HDD for their D drive.
3. Look for the Phisical & Logical combinations, 6 physical * 2 logical means you get 12 threads in total. There are some cpu that only has 1 logical like the 6 threads i5 9600k which has 6 physical but only has 1 logical, so you'll get 6 threads.
