  • Ultra 0 AA= 3.8GB
  • Ultra 2xMSAA= 4.2GB
  • Ultra 4xMSAA= 4.6GB

Win 7 with aero disabled i got about 300-400mb less VRAM use. But Ultra settings with no AA was still above 3gb vram use.

I posted in the surround thread to, will check your posting. I posted this if you are lazy:

Anandtech has a great article now about 1440p max settings (not surround)

http://anandtech.com/show/7189/choosing-a-gaming-cpu-september-2013/10

Onoe the things I love is how they mention my 1366 platform and can still "somewhat compete" even with today's setup: LONG QUOTE, But GREAT READ (Click to show)
Quote:
If you invested in an i7-920, like I did, and are lucky enough to run a nice D0 stepping CPU, then some bases are covered on the single and dual GPU front, although there are some holes were Nehalem is clearly not with the leading pack of CPUs.

Of course with socket 1366 CPUs there are some compromises. The motherboards with these CPUs do not have PCIe 3.0 (which is shown to look important in multi-GPU setups), nor do not have USB 3.0 / SATA 6 Gbps native, meaning you’ll be scrounging around for mid-performing controllers at best. Features such as Thunderbolt are but a wish unless you are willing to upgrade.

The most direct comparison for us is the i7-950 to the i7-4770K – here we have two processors both quad core with hyperthreading, with the 4770K taking a small MHz lead and a large IPC lead. Going back through our benchmark scenarios, the 4770K needs a PLX board to support some nice 3- and 4- way GPU setups, but there is a clear CPU advantage on the side of Haswell. The triple channel memory support of Nehalem was a big plus point when it was launched, but as we can now kit out our dual channel mainstream platforms with 2400 C10 memory with relative ease (or more if you are that way inclined), that memory bandwidth advantage is shorter.

If you were lucky/rich enough to jump on the extreme end of Westmere (i7-980, i7-980X or i7-990X), then having that hex-core system will keep a small advantage in multithreaded tests over the top performing Haswell solution (PovRay on 4770K = 1612.68, on i7-990X = 1636.40). The IPC advantage that Haswell comes with shows itself to be useful in most multi-GPU setups, whereas for our other single and some dual GPU benchmarks the performance difference between the two processors is almost negligible. When you hit three-way GPU configurations, it is all about the lane counts.

Now what would be interesting.... Upgrade now to a 980x or really spend the $1,500 on an Asus RIVE, 4930K/3930K 16-32GB of Ram and see how my Surround 1600p SLI Titan will really jump...


Still inconclusive imo
Quote:
Across our benchmark range, the i7-4960X and i7-4770K are similar in results, where single and dual GPU results are on par with each other across the board. When we start moving into tri-GPU setups, there are several things to consider:

In general:

- the x8/x8 + x4 PCIe allocation on Z87 is bad
- the x8/x4/x4 PCIe allocation on Z87 fares better
- having a PLX chip on a Z87 for x16/x8/x8 is best, but this more expensive
- You don’t have to worry about this with an i7-4960X
- But going Ivy Bridge-E is more expensive to begin with

I'd like to know what you come up with on the E11. My only issue with the way the E11 is PCI-E wired is the two PLX chips don't directly communicate. In say 4-way, cards 1 and 2 can use the full 16x between each other, and cards 3 and 4 can do the same. For cards 1 and 2 to talk to cards 3 and 4, all of that communications has to go through the root 16x lane each PLX is connected to the CPU.

Since SLI/Crossfire only goes as fast as the slowest card/link in AFR, I am not sure how much that config will help in a 4-way setup. PLX chips are also very sensitive to overclocking and you can generally overclock a native host PCI-E setup higher. I run my RIVE at 106MHz bus, versus if I remember correctly my E11 PLX's pooped out at around 101-102.

Good point Vega. I am doing all my testing with both stock configuration except for CPU. The lead is back and forth with the ones i tested. So far it looks like the RIVE has the lead in benchmarks and the Extreme 11 has the lead in games, a couple games by a lot.

One big thing to note is the Extreme 11 requires less voltage for CPU OC stability vs the RIVE. I guess the E11's 24 + 2 Power Phase design is helping out.

do you actually see a difference in number's OCing the pci-e host? I'm going to have to look into this on my RiVE:Be which should be here by the end of the week, god willing.

It's true. On my E11, it used lower volts to overclock my 3960X to the same stable speed than my RIVE. I don't know if it's a reporting thing, or power design, but the E11 is a great CPU overclocker.

Thanks for the awesome benchmarks and really pushing the limit! I've been considering building a triple monitor setup and is torn between 3 x 1080p or 3 x 1440p monitors. The price difference is almost none due to the cheap Korean PLS screens, so I've been reading this thread closely.

Please update us on BF4 and on the ram usage. I don't know if I'm willing to dish out for 3+ titans, but I think I can swing 3 x GTX 780s with the new price drop. I'm just concerned about the vram limitations of 3GB vs 6GB at these resolutions.

My primary games would be BF4, flight (DCS), and car sims.


I'm still on my i7-930 rig, but I was considering building a new rig just for a triple monitor setup and build my father a much better office computer with my old parts.
