The contestants are lined up in [H]ard|OCP's test bench, at around $700 you have a pair of GTX 970's and in the same weight class are a pair of R9 290X cards, next weighing in at just under $550 are two R9 290s, and rounding out the completion are a pair of GTX 780's who punch somewhere between $800 to $1000 depending on when you look.  The cards are tested for their ability to perform on a 4K stage as well as in the larger 5760x1200 multi-monitor event.  After a long and gruelling battle the extra work the 290X put into trimming its self down and fitting into a lower weight class has proven to be well worth the effort as they managed to show up the 970's in every performance category although certainly not in power efficiency.  Any of these pairings will be powerful but none can't match a pair of GTX 980's who are also in a price class all by themselves.

Gigabyte Wants All Your Money for a 3-Way SLI Watercooled GTX 980 Setup

Subject: Graphics Cards | November 14, 2014 - 11:46 AM |
Tagged: sli, nvidia, N980X3WA-4GD, maxwell, GTX 980, gigabyte, geforce, 3-way

Earlier this week, a new product showed up on Gigabyte's website that has garnered quite a bit of attention. The GA-N980X3WA-4GD WaterForce Tri-SLI is a 3-Way SLI system with integrated water cooling powered by a set of three GeForce GTX 980 GPUs.

That. Looks. Amazing.

What you are looking at is a 3-Way closed loop water cooling system with an external enclosure to hold the radiators while providing a display full of information including temperatures, fans speeds and more. Specifications on the Gigabyte site are limited for now, but we can infer a lot from them:

  • WATERFORCE :3-WAY SLI Water Cooling System
  • Real-Time Display and Control
  • Flex Display Technology
  • Powered by NVIDIA GeForce GTX 980 GPU
  • Integrated with 4GB GDDR5 memory 256-bit memory interface(Single Card)
  • Features Dual-link DVI-I / DVI-D / HDMI / DisplayPort*3(Single Card)
  • BASE: 1228 MHz / BOOST: 1329 MHz
  • System power supply requirement: 1200W(with six 8-pin external power connectors)

waterforce2.jpg

The GPUs on each card are your standard GeForce GTX 980 with 4GB of memory (we reviewed it here) though they are running at overclocked base and boost clock speeds, as you would hope with all that water cooling power behind it. You will need a 1200+ watt power supply for this setup, which makes sense considering the GPU horsepower you'll have access to.

Another interesting feature Gigabyte is listing is called GPU Gauntlet Sorting.

With GPU Gauntlet™ Sorting, the Gigabyte SOC graphics card guarantees the higher overclocking capability in terms of excellent power switching.

Essentially, Gigabyte is going to make sure that the GPUs on the WaterForce Tri-SLI are the best they can get their hands on, with the best chance for overclocking higher than stock.

Setup looks interesting - the radiators and fans will be in the external enclosure with tubing passing into the system through a 5.25-in bay. It will need to have quick connect/disconnect points at either the GPU or radiator to make that installation method possible.

Pricing and availability are still unknown, but don't expect to get it cheap. With the GTX 980 still selling for at least $550, you should expect something in the $2000 range or above with all the custom hardware and fittings involved.

Can I get two please?

What, me jealous? Four weeks with SLI'd GTX 980s

Tagged: sli, nvidia, GTX 980

Just in case you need a reason to be insanely jealous of someone, [H]ard|OCP has just published an article covering what it is like to be living with two GTX 980's in SLI.  The cards are driving three Dell U2410 24" 1920x1200 displays for a relatively odd resolution of 3600x1920 but apart from an issue with the GeForce Experience software suite the cards have no trouble displaying to all three monitors.  In their testing of Borderlands games they definitely noticed when PhysX was turned on, though like others [H] wishes that PhysX would abandon its proprietary roots.  When compared to the Radeon R9 290X CrossFire system the performance is very similar but when you look at heat, power and noise produced the 980's are the clear winner.  Keep in mind a good 290X is just over $300 while the least expensive GTX 980 will run you over $550.

"What do you get when you take two NVIDIA GeForce GTX 980 video cards, configure those for SLI, and set those at your feet for four weeks? We give our thoughts and opinions about actually using these GPUs in our own system for four weeks with focus on performance, sound profile, and heat generated by these cards."

SLI Setup and Testing Configuration

The idea of multi-GPU gaming is pretty simple on the surface. By adding another GPU into your gaming PC, the game and the driver are able to divide the workload of the game engine and send half of the work to one GPU and half to another, then combining that work on to your screen in the form of successive frames. This should make the average frame rate much higher, improve smoothness and just basically make the gaming experience better. However, implementation of multi-GPU technologies like NVIDIA SLI and AMD CrossFire are much more difficult than the simply explanation above. We have traveled many steps in this journey and while things have improved in several key areas, there is still plenty of work to be done in others.

As it turns out, support for GPUs beyond two seems to be one of those areas ready for improvement.

IMG_9993.JPG

When the new NVIDIA GeForce GTX 980 launched last month my initial review of the product included performance results for GTX 980 cards running in a 2-Way SLI configuration, by far the most common derivative. As it happens though, another set of reference GeForce GTX 980 cards found there way to our office and of course we needed to explore the world of 3-Way and 4-Way SLI support and performance on the new Maxwell GPU.

The dirty secret for 3-Way and 4-Way SLI (and CrossFire for that matter) is that it just doesn't work as well or as smoothly as 2-Way configurations. Much more work is put into standard SLI setups as those are by far the most common and it doesn't help that optimizing for 3-4 GPUs is more complex. Some games will scale well, others will scale poorly; hell some even scale the other direction.

Let's see what the current state of high GPU count SLI is with the GeForce GTX 980 and whether or not you should consider purchasing more than of these new flagship parts.

Quick Performance Comparison

Earlier this week, we posted a brief story that looked at the performance of Middle-earth: Shadow of Mordor on the latest GPUs from both NVIDIA and AMD. Last week also marked the release of the v1.11 patch for Sniper Elite 3 that introduced an integrated benchmark mode as well as support for AMD Mantle.

I decided that this was worth a quick look with the same line up of graphics cards that we used to test Shadow of Mordor. Let's see how the NVIDIA and AMD battle stacks up here.

For those unfamiliar with the Sniper Elite series, the focuses on the impact of an individual sniper on a particular conflict and Sniper Elite 3 doesn't change up that formula much. If you have ever seen video of a bullet slowly going through a body, allowing you to see the bones/muscle of the particular enemy being killed...you've probably been watching the Sniper Elite games.

screen3.jpg

Gore and such aside, the game is fun and combines sniper action with stealth and puzzles. It's worth a shot if you are the kind of gamer that likes to use the sniper rifles in other FPS titles.

But let's jump straight to performance. You'll notice that in this story we are not using our Frame Rating capture performance metrics. That is a direct result of wanting to compare Mantle to DX11 rendering paths - since we have no way to create an overlay for Mantle, we have resorted to using FRAPs and the integrated benchmark mode in Sniper Elite 3.

Our standard GPU test bed was used with a Core i7-3960X processor, an X79 motherboard, 16GB of DDR3 memory, and the latest drivers for both parties involved. That means we installed Catalyst 14.9 for AMD and 344.16 for NVIDIA. We'll be comparing the GeForce GTX 980 to the Radeon R9 290X, and the GTX 970 to the R9 290. We will also look at SLI/CrossFire scaling at the high end.

Excuse Me, Your SLI Is Glowing

Tagged: sli, nvidia

SLI Bridges are thrown in with compatible motherboards and there is usually little reason to want anything else. They work. There is no performance advantage for getting a "better" one, unless it does not connect with your specific arrangement of two-to-four cards. Today, NVIDIA gives another reason: a soft, beautiful glow to match the green "GeForce GTX" on the cards themselves.

nvidia-sli-bridge.png

Mind you, this is not the first glowing SLI Bridge. EVGA even provided us with a few of their own for a giveaway last year.

NVIDIA has three models, depending on the layout of your cards. 3-way SLI will need to be arranged as a series of two-wide with no gaps, using the "3-Way SLI Bridge". 2-way configurations have the choice of two empty slots between the two-wide cards, or no gap; former would purchase the "2-Way Spaced SLI Bridge" and the later, the "2-Way SLI Bridge". They each require GeForce GTX 770 cards, or better, as well as a recent GeForce Experience (1.7+). Certain non-reference designs may be incompatible.

The SLI Bridges are available now. Both 2-Way bridges are $29.99 and the 3-Way is $39.99.

This high end multi-GPU 4k showdown includes overclocking

Tagged: asus, gtx 780, R9 290X DC2 OC, sli, crossfire, STRIX GTX 780 OC 6GB, R9 290X

We have seen [H]ard|OCP test ASUS' STRIX GTX 780 OC 6GB and R9 290X DirectCU II before but this time they have been overclocked and paired up for a 4k showdown.  For a chance NewEgg gives the price advantage to AMD, $589 versus $599 at the time of writing (with odd blips in prices on Amazon).   The GTX 780 has been set to 1.2GHz and 6.6GHz while the 290X is 1.1GHz and 5.6GHz, keep in mind dual GPU setups may not reach the same frequencies as single cards.  Read on for their conclusions and decide if you prefer to brag about a higher overclock or have better overall performance.

"We take the ASUS STRIX GTX 780 OC 6GB video card and run two in SLI and overclock both of these at 4K resolutions to find the ultimate gameplay performance with 6GB of VRAM. We will also compare these to two overclocked ASUS Radeon R9 290X DirectCU II CrossFire video cards for the ultimate VRAM performance showdown."

ASUS STRIX GTX 780 OC 6GB in SLI, better than a Titan and less expensive to boot!

Subject: Graphics Cards | July 4, 2014 - 01:40 PM |
Tagged: STRIX GTX 780 OC 6GB, sli, crossfire, asus, 4k

Multiple monitor and 4k testing of the ASUS STRIX GTX 780 OC cards in SLI is not about the 52MHz out of box overclock but about the 12GB of VRAM that your system will have.  Apart from an issue with BF4, [H]ard|OCP tested the STRIX against a pair of reference GTX 780s and HD 290X cards at resolutions of 5760x1200 and 3840x2160.   The extra RAM made the STRIX shine in comparison to the reference card as not only was the performance better but [H] could raise many of the graphical settings but was not enough to push its performance past the 290X cards in Crossfire.  One other takeaway from this review is that even 6GB of VRAM is not enough to run Watch_Dogs with Ultra textures at these resolutions.

Linus Brings SLI and Crossfire Together

Subject: General Tech, Graphics Cards | February 7, 2014 - 03:54 AM |
Tagged: sli, crossfire

I will not even call this a thinly-veiled rant. Linus admits it. To make a point, he assembled a $5000 PC running a pair of NVIDIA GeForce 780 Ti GPUs and another pair of AMD Radeon R9 290X graphics cards. While Bitcoin mining would likely utilize all four video cards well enough, games will not. Of course, he did not even mention the former application (thankfully).

No, his complaint was about vendor-specific features.

Honestly, he's right. One of the reasons why I am excited about OpenCL (and its WebCL companion) is that it simply does not care about devices. Your host code manages the application but, when the jobs get dirty, it enlists help from an available accelerator by telling it to perform a kernel (think of it like function) and share the resulting chunk of memory.

This can be an AMD GPU. This can be an NVIDIA GPU. This can be an x86 CPU. This can be an FPGA. If the host has multiple, independent tasks, it can be several of the above (and in any combination). OpenCL really does not care.

The only limitation is whether tasks can effectively utilized all accelerators present in a machine. This might be the future we are heading for. This is the future I envisioned when I started designing my GPU-accelerated software rendering engine. In that case, I also envisioned the host code being abstracted into Javascript - because when you jump into platform agnosticism, jump in!

Obviously, to be fair, AMD is very receptive to open platforms. NVIDIA is less-so, and they are honest about that, but they conform to standards when it benefits their users more than their proprietary ones. I know that point can be taken multiple ways, and several will be hotly debated, but I really cannot find the words to properly narrow it.

Despite the fragmentation in features, there is one thing to be proud of as a PC gamer. You may have different experiences depending on the components you purchase.

But, at least you will always have an experience.
