If you are going to set up a multimonitor display at 5760x1200 or 5040x1050, but only have a single GPU or a pair of low powered ones, just what kind of performance can you expect? That is the question Techgage wanted to answer and to that purpose they tested frame rates at those resolutions with NVIDIA's GTX680 and two different 660 Ti's in SLI as well as an HD7970 and two different 7850s in Crossfire. As you might expect the game tested makes a lot of difference in the results, with many seeing the SLI'd 660 Ti's in the lead while other memory hungry games preferred the large cache of the Radeons. Check out the individual results of your favourite games in the full article.
"Considering next-gen cards are still months away, we didn't expect to bring any more GPU reviews until the second quarter of 2013. However, we realized there was a gap in our current-gen coverage: triple-monitor gaming. In fact, it's been almost two years since we last stress tested games at resolutions of up to 7680x1600.
We're going to mix things up a little this time. Instead of using each camp's ultra-pricey dual-GPU card (or the new $999 Titan), we're going to see how more affordable Crossfire and SLI setups handle triple-monitor gaming compared to today's single-GPU flagships."

For the tests they ran, [H]ard|OCP used the latest Catalyst beta, 12.6 and ForceWare 301.42 WHQL as both drivers proved able to provide proper multi-GPU performance on Max Payne 3. In AMD's case it provided improvements to single card gaming as well. The games graphics options provide a nice tool which displays how much VRAM your configuration will require so that you can get an idea if your card will be able to handle the settings before you even play the game. SLI did scale better than Crossfire but even still, both multi GPU rigs could handle the max settings at 2560x1600 and when used singly could still sit around the 60fps mark. Check out the full review here.
"HardOCP is on top of Max Payne 3 to find out what graphics options it supports and how a GTX 680 and a Radeon HD 7970 perform. We also wanted to know if SLI and CrossFireX worked, and how performance scales. In this preview of performance and image quality we take a look at all of this in the first chapter of this game."

Retail-ready HD 7970
We first showed off the power of the new AMD Radeon HD 7970 3GB graphics card in our reference review posted on December 22nd. If you haven't read all about the new Southern Islands architecture and the Tahiti chip that powers the HD 7970 then you should already be clicking the link above to my review to get up to speed. Once you have done so, please return here to continue.
Welcome back, oh wise one. Now we are ready to proceed. By now you already know that the Radeon HD 7970 is the fastest GPU on the planet, besting the NVIDIA GTX 580 by a solid 20-30% in most cases. For our first retail card review we are going to be looking at the XFX Black Edition Double Dissipation that overclocks the GPU and memory clocks slightly and offers a new cooler that promises to be more efficient and quieter.
Let's put XFX to the test!
The XFX Radeon HD 7970 3GB Black Edition Double Dissipation
Because of the use of a completely custom cooler, the XFX HD 7970 Black Edition Double Dissipation looks completely different than the reference model we tested last month though the feature set remains identical. The silver and black motif works well here.

Why shouldn't you stick a pair of HD 6990M's in an 18.4" laptop, as long as you don't mind lugging around a 12lb laptop from power outlet to power outlet. Seeing as just a few years ago 12lbs was not an uncommon weight for a laptop that does represent a great design on Alienware's part. The comparison that AnandTech was most interested in was between NVIDIA's GTX 580M and AMD's 6990M to see who can hold onto the dual GPU mobile performance crown. Who shall triumph? Read on to see.
"In our first run with the Alienware M18x, we sat down and took a look at the notebook itself along with NVIDIA's current top shelf mobile graphics part, the GeForce GTX 580M. We came away from the experience with mixed impressions of the M18x itself, a notebook that is by all means incredibly powerful but also seems to lose a lot of the balance that made the M17x R3 so desirable. On the other hand, the GeForce GTX 580M wound up being the fastest mobile GPU we'd yet tested, made only more formidable through the SLI configuration the M18x enables."

Tagged: bulldozer, fx-8150, crossfire, gaming
One of the questions we have been asking about Bulldozer is how much it effects game play performance. We know that for non-multithreaded applications th FX-8150 falls behind the top SandyBridge processors and barely breaks even on heavily multithreaded apps. That doesn't necessarily mean that it will lag behind SandyBridge in gaming as many games do not utilize the CPU enough to make a huge difference, though that premise needs to be proved. Enter Tweaktown who have taken the top Bulldozer and SandyBridge CPUs along with three Sapphire HD 6970 video cards, and placed them in a Maximus IV Extreme-Z and Crosshair V Formula motherboard respectively. With that much graphical power, it is possible to see the performance difference that the CPU and the motherboard chipset have on performance. Read on to see how Bulldozer fared.
"We've already provided a fair bit of coverage on the new FX-8150 CPU from AMD and it hasn't all been favorable for the team over at AMD. If you haven't looked yet, I highly recommend you check out our other pieces that cover the VGA testing side of things and my editorial Shi**y Marketing Killed the Bulldozer Star which has really gained traction over the last few days.
Today we test the video card side of things a bit more and see what goes on when we start to make use of CrossFireX on the 990FX platform. The 990FX chipset shows some good potential and it's going to be interesting to see what happens when we start to make use of all those PCIe lanes that are on offer."

The GIGABYTE HD6770 Silent Cell is a different take on your normal HD6770, it has no fans but does sport a double wide heatsink. Sporting all of GIGABYTE's Ultra Durable components you can pick up this card for a hair under $140; or more importantly for [H]ard|OCP's review you can pick up two for about the same price as an HD6950 or a GTX 570 if you can find one on sale. Their testing showed that at a resolution of 1920x1200 the two HD6770's could hold their own but they quickly fell behind the competition when resolution was raised beyond that point, which would include EyeFinity. If your case has the space for the coolers and you have an overwhelming urge to play games at a 1080p resolution on a silent machine, then these cards are for you. Apart from that goal, you are better served with a single higher power GPU.
"Today we'll find out if two of GIGABYTE's HD6770 Silent Cell cards can match the performance of a Radeon HD 6950. We were impressed with how this no-fan silent configuration CrossFireX setup performed. However, is it worth $280 against the falling prices of the Radeon HD 6950?"

The Dirty Laggard
It may seem odd, but sometimes reviewers are some of the last folks to implement new technology. This has been the case for myself many a time. Yes, we get some of the latest and greatest components, but often we review them and then keep them on the shelf for comparative purposes, all the while our personal systems run last generation parts that we will not need to re-integrate into a test rig ever again. Or in other cases, big money parts, like the one 30” 2560x1600 LCD that I own, are always being utilized on the testbed and never actually being used for things like browsing, gaming, or other personal activities. Don’t get me wrong, this is not a “woe-is-me” rant about the hardships of being a reviewer, but rather just an interesting side effect not often attributed to folks who do this type of work. Yes, we get the latest to play with and review, but we don’t often actually use these new parts in our everyday lives.
One of the technologies that I had only ever seen at trade shows is that of Eyefinity. It was released back in the Fall of 2009, and really gained some momentum in 2010. Initially it was incompatible with Crossfire technology, which limited it to a great degree. A single HD 5970 card could push 3 x 1920x1080 monitors in most games, but usually only with details turned down and no AA enabled. Once AMD worked a bit more on the drivers were we able to see Crossfire setups working in Eyefinity, which allowed users to play games at higher fidelity with the other little niceties enabled. The release of the HD 6900 series of cards also proved to be a boon to Eyefinity, as these new chips had much better scaling in Crossfire performance, plus were also significantly faster than the earlier HD 5800 series at those price points.
Continue on to the rest of the story for more on my experiences with AMD Eyefinity.

Tagged: llano, dual graphics, crossfire, APU, amd, a8-3850, 3850
Last week we posted a short video about the performance of AMD's Llano core A-series of APUs for gaming and the response was so positive that we have decided to continue on with some other short looks at features and technologies with the processor. For this video we decided to investigate the advantages and performance of the Dual Graphics technology - the AMD APU's ability to combine the performance of a discrete GPU with the Radeon HD 6550D graphics integrated on the A8-3850 APU.
For this test we set our A8-3850 budget gaming rig to the default clock speeds and settings and used an AMD Radeon HD 6570 1GB as our discrete card of choice. With a price hovering around $70, the HD 6570 would be a modest purchase for a user that wants to add some graphical performance to their low-cost system but doesn't stretch into the market of the enthusiast.
The test parameters were simple: we knew the GPU on the Radeon HD 6570 was a bit better than that of the A8-3850 APU so we compared performance of the discrete graphics card ALONE to the performance of the system when enabling CrossFire, aka Dual Graphics technology. The results are pretty impressive:
You may notice that these percentages of scaling are higher than those we found in our first article about Llano on launch day. The reasoning is that we used the Radeon HD 6670 there and found that while compatible by AMD's directives, the HD 6670 is overpowering the HD 6550D GPU on the APU and the performance delta it provides is smaller by comparison.
So, just as we said with our APU overclocking video, while adding in a discrete card like the HD 6570 won't turn your PC into a $300 graphics card centered gaming machine it will definitely help performance by worthwhile amounts without anyone feeling like they are wasting the silicon on the A8-3850.

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."

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!
"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."
