nVidia 670 GTX – Single GPU vs SLI Comparison

670 SLI

Hey guys! Omning here with a quick bit of data for you, comparing the nVidia 670 to 670-SLI.

 

Recently I updated my system to SLI 670’s, and to be honest I wasn’t expecting a huge increase in numbers or performance.  My reasoning is, my rig is pretty beefy already, and I’m only running a single 1080p monitor, so getting a big boost from another 670 just didn’t seem like it was going to happen.  I’m very happy to report that i was totally and completely wrong!

Test system:

  • Intel Core i7 2600k @ 4.5ghz
  • G.SKILL Ripjaws Z Series 16gb @ 1600
  • EVGA Z68 SLi
  • EVGA 670 2gb (x2 in SLI benchmarks)
  • 2 x Kingston HyperX 3K 120GB SATA III SSD
  • Corsair AX1200 PSU
  • NZXT Switch 810 Matte Black
  • Custom Watercooling loop (Black Ice Stealth GT 420, NZXT Enthusiast Fans, Raystorm CPU block, XSPC X2O DC-750 res/pump)
  • GPU’s using stock cooling

First lets compare everyones favorite benchmarking program, 3D Mark 2011.  This is a basic test, with option of “Benchmark Only” selected.

 

As you can see there’s a significant increase on 3dmark score.

 

Next up is my personal favorite First Person Shooter right now – Battlefield 3.  These numbers were gathered using FRAPS, with everything in BF3 set to Ultra, and running through the games first level (Semper Fi).  FRAPS was started as soon as the player is on top of the train, and stopped right as the screen goes black.

 

Uhh… holy crap?  The Min is nearly the the Max when comparing Single to SLI.  The jump for Avg is nothing short of astonishing!

 

Last benchmark for me is Diablo 3.  I know, I know, Diablo 3 barely taxes any “Gaming” system, but I play it enough hours per week that I figured it was warranted 🙂  All settings maxed, 1080, V-Sync turned off.  Benchmarks were gathered in a Defiled Crypt in the Act 1 graveyard, Inferno mode, with my WW Barbarian.  All mobs were killed including all packs.

 

Again, there’s not much that can be said here.  The numbers do all the talking we need.  This means I could easily run this on a 120hz monitor with no issues at all.  And that sound awesome.

 

That’s it for now guys!  No lengthy conclusions or anything here.  I’ll leave you with this:

If you’ve been thinking of going SLI and can afford it…. do it.
