The only thing better than an in stock GTX 680 would be two of them

The name of the game in [H]ard|OCP's latest review is scaling at 5760 x 1200, specifically the scaling of two GTX 680s in SLI as well as a pair of HD 7970s in Crossfire.  Some games like Mass Effect 3 will not benefit much as the difference between 150fps and 170fps will be hard to do but others such as Battlefield 3 and Arkham City stress these cards somewhat at this resolution, but even 50fps is rather impressive when pushing about 7 million pixels.  Read on and be prepared to feel a little jealous, maybe jealous enough to snatch up a Galaxy model which is back in stock. (didn't last 2 minutes)

"We've got two GeForce GTX 680 video cards to test SLI performance against Radeon HD 7970 CrossFireX. Will these less expensive GTX 680 video cards offer a better gameplay experience or choke at high resolutions due to a smaller VRAM footprint? We will prove to you which solution offers better efficiency and performance."

GTX 680 insanity! SLI, Triple SLI, and Quad SLI

Subject: Graphics Cards | March 23, 2012 - 10:45 AM |
Tagged: sli, quad sli, gtx 680

With an Intel Core i7 3960X, 16GB of DDR3, an ASUS Rampage IV Formula motherboard and an Enermax Platimax 1500W PSU, Hardware.Info took four GTX 680s and started benchmarking.  Of course, that means more than one monitor so these benchmarks are at 5760x1080 and due to the new architecture some games were not quite sure what to do with the extra graphics cards.  Some games like Metro 2033 were not able to provide significant scaling at high resolutions but then again Crysis 2 had no idea what to do with three HD 7970s which makes it hard to determine a clear winner between three HD 7970s and four GTX 680s.  The benchmark results offer results we've never seen, with over 80fps from the NVIDIA cards on Crysis 2 and 130fps on Skyrim.  The end result is that apart from games which seem to need updating, the scaling of the GTX 680 is impressive and it pulls less power than the HD 7970s.

"We just published a comprehensive GeForce GTX 680 4-way SLI review on Hardware.Info. Since we are the first to extensively test a Quad-SLI configuration of nVidia's brand new GeForce GTX 680, we wanted to make these exciting results available to a wider audience and created an English version of the article."

NVIDIA SLI Breaks EVGA GTX 560 Ti 2Win and X79 Combinations

Subject: Graphics Cards | December 16, 2011 - 01:39 PM |
Tagged: x79, sli, evga, GTX 560 Ti, 2win

Sometimes, the best intentions fumble out of the gates.  When we reviewed the EVGA GeForce GTX 560 Ti 2Win graphics card in November, I gave it a glowing review as a product that offered better performance than the GTX 580 while selling at a very similar price (currently just $20 more).  My test configuration at the time included an X58 motherboard based on the Nehalem architecture that has been tried and tested over the years.

For the forthcoming review of the Radeon HD 7970 graphics card, we decided to move our GPU test bed to the new X79-based Sandy Bridge-E platform since it was the new hotness and because it continued to be the best option for multi-GPU configurations going forward.  Or so we thought.

While preparing for our review, I was configuring our NVIDIA cards due for re-testing on this platform and brought the GTX 560 Ti 2Win out from the back room.  However, no matter which driver I used, I was unable to enable SLI on it and running a quick performance test confirmed we were running in a single GPU configuration.  We used driver versions from the 285.xx stack as well as the 290.xx stack - all with the same results.

x79sli2.jpg

Both GPUs were enabled and would show up in the Windows Device Manager AND inside the NVIDIA control panel.  However, the standard SLI configuration switch was nowhere to be found.  We only had the ability to select enabling PhysX on different the GPUs...

After a quick talk with both NVIDIA and EVGA we confirmed this to be a bug with the EVGA GTX 560 Ti 2Win and the X79 platform as a whole.  Why?  Apparanetly a driver fix is in the works - it is all simply a software issue.  A new version is "coming soon" though no specific dates were given.  If you have one of these cards and upgraded to an X79 motherboard, we apologize for you only being able to utilize half of your investment.

Which brings me back to my consistent stance - NVIDIA's SLI Technology would be better served as an openly available multi-GPU solution without the restrictions of licensing and software hacks.  Why?  The money that NVIDIA makes on the licensing is pretty minimal and the only goal is to uphold the "value" of the SLI brand.  Instead, everytime a hiccup like this occurs, more gamers decide that the benefits aren't worth the potential hassle owning multiple graphics cards may cause.  

CrossFireX doesn't have nearly the marketing push behind it that SLI does yet it continues to have legs without the rather outdated partner licensing restrictions.  Every multiple PCIe slot motherboard (essentially) will support CrossFireX - users that might want SLI configurations need to look for that damn logo on the box...

Puget Systems will build you a Sandy Bridge E system

If you want to get your hands on a pre-built Sandy Bridge E system you could do worse than the Puget Systems Deluge.  You get the Core i7-3960X on an ASUS Sabertooth X79 with 32GB of 1500MHz Patriot Viper Xtreme DDR3, a pair of EVGA GTX580s and both an Intel 510 250GB SSD and a 2TB WD Caviar Black for storage.  The whole system is cooled with a custom watercooler with a 360mm radiator and will only cost $7,254.  The system does give you enough power to game in NVIDIA Surround with decent frame rates, but AnandTech is of the opinion that this system is perhaps a bit too powerful.  So much of the capability of this system is not utilized by even the most demanding of games, and what is needed can be duplicated with parts that have a much smaller price tag.  However if you need the bragging rights then this system is for you.

"It's been a little while since we've had a Puget Systems desktop in, and so far we haven't yet tested any of their big dog gaming machines. Everything else we've tested, we've liked, but what happens when the fine folks over at Puget Systems pull out all the stops and put together a high end gaming machine? The answer: the Deluge, an X79-based rig in a modified Antec P183, employing a custom liquid-cooling loop. It's big, powerful, and expensive. Did Puget Systems hit another custom out of the park, and is Sandy Bridge-E the enthusiast platform we were waiting for?"

See what happens when you harness three GPUs to a Bulldozer and try to get them to pull it along

Subject: Processors | November 9, 2011 - 01:05 PM |
Tagged: amd, bulldozer, sli, FX 8150, GTX580

In a good mood?  If so, do not read this [H]ard|OCP article on Bulldozer's gaming performance when coupled with two and three GTX580s.  By using an SLI setup you can see just how powerful a CPU is as it tries to keep up with the GPUs and as you might expect the Bulldozer is not up to the task.  In most tests [H] saw a 70% performance difference between the FX 8150 and the Core-i5 2500K, with both processors clocked at 4.8GHz.  In a very few tests the results were a little closer but this is bad news for AMD, especially when you consider it is the more expensive of the two chips.

Battlefield 3 (BF3) Beta Performance: Quality Preset and SLI Scaling

Subject: Editorial, General Tech, Graphics Cards | October 1, 2011 - 10:49 AM |
Tagged: sli, gtx 570, gtx 460, bf3, battlefield 3

I know, we've been talking a lot about Battlefield 3 this week, but I have yet another set of numbers and results that I think you guys will want to see.  Previously, all of our BF3 benchmarks have been run under the Ultra quality presets but it is obvious that not all GPUs or gamers are going to want to target the highest settings the game can accomplish.  With that in mind I decided to test a couple of cards at Ultra, High, Medium and Low presets in order to guage how well the game scaled based on image quality.

For this round I wanted to use a high end card as well as an older, much more popular (and currently low cost) card; the result is tests on the GeForce GTX 570 1.25GB and the GeForce GTX 460 1GB reference platforms.  We used the Operation Metro map and the initial outdoor section for our testing as it was the most strenuous in the beta thus far.

As a side note, if you want to see how the image quality actually changes from the Ultra, High, Medium and Low presets, check out this page of my previous performance article that included screenshots and even some animated GIFs as demonstration.

Here are the results:

bf3scaling1-1920.jpg

bf3scaling1-1920-bar.jpg

On the more powerful GTX 570 you can see that BF3 scales pretty well from the Ultra settings through the Low options in even steps.  By moving from Ultra down to High a gamer would see about 34% better performance and 22% better minimum frame rates.  The jump to Medium gains another 41% while the move to Low gets another 25% on top of that.  The gap between Low and Ultra is about ~2.3x.

bf3scaling2-1920.jpg

bf3scaling2-1920-bar.jpg

The GTX 460 sees similar levels of performance grades though the move from Ultra to High only gains you about 28% and averages of 33.8 FPS or so.  I would still consider that on the low side of a good game play experience and thus the move to Medium (which is 82% faster than Ultra) seems like the sweet spot for BF3.  

I know we also had some requests for SLI scaling performance and, in particular, with the GTX 460 1GB cards.  Since this card has been so incredibly popular we thought this would be the perfect candidate for the "SLI Upgrade Path" option and you can pick one up for $150 (or less with rebates).  Let's see how well Battlefield 3 scales with multiple GPUs.

bf3sli1-1920.jpg

bf3sli1-1920-bar.jpg

At the Ultra quality settings we saw a 60% scaling capability by adding in a second GTX 460 at stock speeds while at High settings we see that rate increases to 84%!  That is pretty impressive and for the cost investment of a second GPU it looks like you are going to see better than average scaling.  Considering this is with the first driver release and with a beta version of the game, I can only see multi-GPU scaling rates going up as the full retail release hits.

With these results and some others we have done through the week we are ready to put together our Battlefield 3 system build guide.  Stay tuned!

Can two overclocked GTX 550 Ti's beat the competition?

Subject: Graphics Cards | August 23, 2011 - 12:33 PM |
Tagged: nvidia, gtx550 ti, msi, sli, N550GTX-Ti Cyclone II

If you put a limit of $300 on your graphics subsystem, you are most likely shopping for an HD6950 or possibly a heavily overclocked GTX 560 Ti or a discounted GTX570.  [H]ard|OCP tested out a different choice, two of MSI's N550GTX-Ti Cyclone II card in SLI, which can also be had for under $300.   The testing did not go so well for NVIDIA's less powerful card, the HD6950 won in almost every test and consumed less energy doing so.  There were certain situations in which they would recommend running the cards in SLI, specifically when you already own a GTX 550 or other lower powered NVIDIA card and don't plan on playing at resolutions above 1920x1200.  Only then would this upgrade make sense.

"Packing a GeForce GTX 550 Ti GPU each, we have a pair of N550GTX-Ti Cyclone II video cards that we are going to evaluate against a Radeon HD 6950, GeForce GTX 570 and even an overclocked GeForce GTX 560 Ti. At a total cost of only $260 we will find out if this dual-GTX 550 Ti action has what it takes to compete. "

Tagged: sli, sapphire, pdxlan, pdx, nvidia, msi, amd

If you are a PC gaming and live near or around the Portland, OR area you are familiar with the concept of PDXLAN - one of the most popular (but still cool and underground) LAN events in the country.  The primary event is going on this weekend and I am here to both game and take a look at what the sponsors are showing off. 

pdx01.jpg

MSI has a lot of stuff going on including a look at the latest version of the Afterburner overclocking tool, the 3GB version of the GTX 580 Lightning (that Josh is currently working on a review of) and even a NVIDIA Surround based Dirt 3 sim seat.

pdx02.jpg

Gaming laptops are still taking off here in the US and MSI has a couple on display including a HUGE 18-in mode (on the right) with a keyboard that lights up with various colors of LEDs, configurable.  

pdx03.jpg

The Sapphire guys are here as well and are showing off much of what AMD for gamers including Eyefinity configurations like the very popular 5x1 portrait mode.  This is something that only AMD offers currently and in this demo we were looking at Dragon Age II.  It was definitely grabbing some attention!

pdx04.jpg

Showing that AMD's HD3D technology does indeed have legs Sapphire was showing off the new Samsung SyncMaster SA950 that has a nice external design.  I am going to spend some more time with it today to see how it performs, so check back for more!

pdx05.jpg

If you are here, you can also find me getting butt kicked at various games.  This is the machine I'll be on, a Maingear built GTX 580 SLI right with an overclocked Intel Core i7 Sandy Bridge processor and 30-in display.  I know, it sucks to be me, but someone has to sacrifice and play on it, right?

More from PDXLAN later today!

Revisiting quad-gpus and the Law of Diminishing Returns

Subject: Graphics Cards | May 24, 2011 - 12:44 PM |
Tagged: quad sli, quad crossfire, sli, crossfire, nvidia, amd

With SLI and CrossFire we all hoped to see direct scaling so that a quad GPU setup would be somewhere in the neighbourhood of 4x better than a single GPU.  That has proven to be incorrect, not only is the scaling nowhere near that it has been discovered that in some cases going beyond 2 GPUs can actually reduce performance.  

As the hardware and drivers evolve, it is worth revisiting the scaling performance of both AMD and NVIDIA which is why [H]ard|OCP grabbed two GeForce GTX 590s and two AMD Radeon HD 6990s, both dual GPU cards.  In three of the five games tested they ran into at least one issue, a strike right off the bat.  Read on to see how they rate the value of the two manufacturers based on the performance they saw once they'd resolved the problems.

"How does NVIDIA's GeForce GTX 590 SLI Quad-GPU compare to AMD's Radeon HD 6990 CrossFireX Quad-GPU? We will find out if these "if-money-didn't-matter dream video card setups" will deliver the gameplay experience we all expect."

Tri-Fire/SLI redux, look at the difference SandyBridge makes!

Subject: Graphics Cards, Processors | May 6, 2011 - 10:09 AM |
Tagged: tri-fire, crossfire, sli, triple, sandybridge

Not too long ago [H]ard|OCP examined the price to performance ratio between a triple SLI GTX580 system and a Tri-Fire HD6990 and HD6970 and discovered that as far as value goes, NVIDIA could not touch AMD.  A reader of theirs inquired if it was the aging Core i7-920 that was holding the cards back even with the overclock of 3.6GHz.  A SandyBridge system with a Core i7-2600K and an ASUS board with the NF200 bridge chip was used to revisit the performance of the two vendors GPUs.  The result; we can hardly wait for the Z68 boards to come out!

H_Proof.gif

"We have re-tested performance between GTX 580 3-Way SLI and Radeon HD 6990+6970 Tri-Fire with a brand new Sandy Bridge 4.8GHz system. Our readers wanted to know if the CPU speed would improve performance and open up the potential of this triple-GPU performance beasts. To put it succinctly, they were right. The results completely turn the tables upside down and then some."
