Performance stats on new i7-3770K rig w/ Samsung 830 SSD

[tankman1989]

I just put together a nice system for a home desktop. the specs are:

Asus P8Z77-V DELUXE
Intel i7-3770k 3.5Ghz Quad core Ivy-Bridge
32GB DDR3-1600 Corsair Vengeance
ASUS GT640-2GD3 GeForce GT 640 2GB 128-bit DDR3
SAMSUNG 830 Series 256GB SSD
6 1GB Seagate 7200rpm/64mb cache SATA III
CORSAIR HX Series HX750 PLUS GOLD Certified 750 watt
ASUS 24X DVD Burner (Model DRW-24B1ST - very solid build & very snappy)
Antec P280 case
Windows 7 64bit Ultimate

So, I set everything up and did a bench test on the SSD R/W rates. I can compare it to my Intel X25-M 80GB on an Intel Q6600 2.4Ghz system that this system replaces.

New system - Samsung 830

Old System - Intel X25-M (With 6GB of RAM in use and LOTS of apps running)

I also did a test on file decompression. The files tested were 3.1GB total size, 70 50MB files rar files. I RDP'd into the new system and extracted the files with Winrar in 78 seconds. I did the same on another system (2.66Ghz Intel E6750 Dual Core) running Ubuntu 12.04 server taking 20 seconds longer at 98 second! This just didn't seem right to me.

I wouldn't have posted this post had it not been for the last test. I'm running a CPU that is half again as fast with twice as many cores and I'm only 20% faster? How is that?

Anyone have any ideas?

Just off the top of my head, if you ignore the number of cores, 2.66 is 76% of 3.5. So the new machines CPU is roughly a 24% increase in speed. Which is about how much faster it was in the decompression than the other. If the number of cores don't play into the decompression 20% faster seems about right. I'm sure there's more to it, just a thought.

Good point. Now I think back to it, I think a lot of programs don't utilize multiple cores or multi-threading. This is one of those processes.

I wonder if programs like Photoshop use multiple cores or even video encoding. That is something I really should know and I'll find out and report back.
