Our 4K Testing Methods
You may have recently seen a story and video on PC Perspective about a new TV that made its way into the office. Of particular interest is the fact that the SEIKI SE50UY04 50-in TV is a 4K television; it has a native resolution of 3840x2160. For those that are unfamiliar with the new upcoming TV and display standards, 3840x2160 is exactly four times the resolution of current 1080p TVs and displays. Oh, and this TV only cost us $1300.
In that short preview we validated that both NVIDIA and AMD current generation graphics cards support output to this TV at 3840x2160 using an HDMI cable. You might be surprised to find that HDMI 1.4 can support 4K resolutions, but it can do so only at 30 Hz (60 Hz 4K TVs won't be available until 2014 most likely), half the refresh rate of most TVs and monitors at 60 Hz. That doesn't mean we are limited to 30 FPS of performance though, far from it. As you'll see in our testing on the coming pages we were able to push out much higher frame rates using some very high end graphics solutions.
I should point out that I am not a TV reviewer and I don't claim to be one, so I'll leave the technical merits of the monitor itself to others. Instead I will only report on my experiences with it while using Windows and playing games - it's pretty freaking awesome. The only downside I have found in my time with the TV as a gaming monitor thus far is with the 30 Hz refresh rate and Vsync disabled situations. Because you are seeing fewer screen refreshes over the same amount of time than you would with a 60 Hz panel, all else being equal, you are getting twice as many "frames" of the game being pushed to the monitor each refresh cycle. This means that the horizontal tearing associated with Vsync will likely be more apparent than it would otherwise.
I would likely recommend enabling Vsync for a tear-free experience on this TV once you are happy with performance levels, but obviously for our testing we wanted to keep it off to gauge performance of these graphics cards.

A New Gigabyte WindForce 450W GPU Cooler May Be Coming to a GTX 680 and Titan Near You
Subject: Graphics Cards | April 14, 2013 - 07:59 PM | Tim Verry
Tagged: windforce, nvidia, gtx titan, gtx 680, gpu cooler, gigabyte
Earlier this week, PC component manufacturer Gigabyte showed off its new graphics card cooler at its New Idea Tech Tour even in Berlin, Germany. The new triple slot cooler is built for this generation's highest-end graphics cards. It is capable of cooling cards with up to 450W TDPs while keeping the cards cooler and quiter than reference heatsinks.
The Gigabyte WindForce 450W cooler is a triple slot design that combines a large heatsink with three 80mm fans. The heatsink features two aluminum fin arrays connected to the GPU block by three 10mm copper heatpipes. Gigabyte stated during the card's reveal that its cooler keeps a NVIDIA GTX 680 graphics card 2°C cooler and 23.3 dB quiter during a Furmark benchmark run. Further, the cooler will allow these high end cards, like the GTX Titan to achieve higher (stable) boost clocks.
ComputerBase.de was on hand at Gigabyte's event in Berlin to snap shots of the upcoming GPU cooler.
The company has not announced which graphics cards will use the new cooler or when it will be available, but A Gigabyte GTX 680 and a custom cooled-Titan seem to be likely candidates considering these cards were mentioned in the examples given in the presentation. Note that NVIDIA has prohibited AIB partners from putting custom coolers on the Titan thus far, but other rumored Titan graphics cards with custom coolers seem to suggest that the company will allow custom-cooled Titans to be sold at retail at some point. In addition to using it for the top-end NVIDIA cards, I think a GTX 670 or GTX 660 Ti GPU using this cooler would also be great, as it would likely be one of the quieter running options available (because you could spin the three 80mm fans much slower than the single reference fan and still get the same temps).
What do you think about Gigabyte's new 450W GPU cooler? You can find more photos over at Computer Base (computerbase.de).
How Games Work
Because of the complexity and sheer amount of data we have gathered using our Frame Rating performance methodology, we are breaking it up into several articles that each feature different GPU comparisons. Here is the schedule:
- 3/27: Frame Rating Dissected: Full Details on Capture-based Graphics Performance Testing
- 3/27: Radeon HD 7970 GHz Edition vs GeForce GTX 680 (Single and Dual GPU)
- 3/30: AMD Radeon HD 7990 vs GeForce GTX 690 vs GeForce GTX Titan
- 4/2: Radeon HD 7950 vs GeForce GTX 660 Ti (Single and Dual GPU)
- 4/5: Radeon HD 7870 GHz Edition vs GeForce GTX 660 (Single and Dual GPU)
- 4/16: Frame Rating: Visual Effects of Vsync on Gaming Animation
Introduction
The process of testing games and graphics has been evolving even longer than I have been a part of the industry: 14+ years at this point. That transformation in benchmarking has been accelerating for the last 12 months. Typical benchmarks test some hardware against some software and look at the average frame rate which can be achieved. While access to frame time has been around for nearly the full life of FRAPS, it took an article from Scott Wasson at the Tech Report to really get the ball moving and investigate how each frame contributes to the actual user experience. I immediately began research into testing actual performance perceived by the user, including the "microstutter" reported by many in PC gaming, and pondered how we might be able to test for this criteria even more accurately.
The result of that research is being fully unveiled today in what we are calling Frame Rating – a completely new way of measuring and validating gaming performance.
The release of this story for me is like the final stop on a journey that has lasted nearly a complete calendar year. I began to release bits and pieces of this methodology starting on January 3rd with a video and short article that described our capture hardware and the benefits that directly capturing the output from a graphics card would bring to GPU evaluation. After returning from CES later in January, I posted another short video and article that showcased some of the captured video and stepping through a recorded file frame by frame to show readers how capture could help us detect and measure stutter and frame time variance.
Finally, during the launch of the NVIDIA GeForce GTX Titan graphics card, I released the first results from our Frame Rating system and discussed how certain card combinations, in this case CrossFire against SLI, could drastically differ in perceived frame rates and performance while giving very similar average frame rates. This article got a lot more attention than the previous entries and that was expected – this method doesn’t attempt to dismiss other testing options but it is going to be pretty disruptive. I think the remainder of this article will prove that.
Today we are finally giving you all the details on Frame Rating; how we do it, what we learned and how you should interpret the results that we are providing. I warn you up front though that this is not an easy discussion and while I am doing my best to explain things completely, there are going to be more questions going forward and I want to see them all! There is still much to do regarding graphics performance testing, even after Frame Rating becomes more common. We feel that the continued dialogue with readers, game developers and hardware designers is necessary to get it right.
Below is our full video that features the Frame Rating process, some example results and some discussion on what it all means going forward. I encourage everyone to watch it but you will definitely need the written portion here to fully understand this transition in testing methods.

A look outside and in
We handle a fair amount of system reviews here at PC Perspective and use them mainly as a way to feature unique and interesting designs and configurations. We know how the hardware will perform for the most part; doing extensive CPU and GPU testing on nearly a daily basis. Sometimes we'll get systems in that are extremely budget friendly, other times vendors pass us machines that have MSRPs similar to a Kia automobile. Then there are times, like today, we get a unique design that is a great mix of both.
AVADirect has had a Mini Gaming PC design for a while now but recently has gone through a refresh that adds in support for the latest Ivy Bridge processors, NVIDIA Kepler GPUs all using a new case from BitFenix that combines it in a smaller, mini-ITX form factor.
The quick specifications look like this:
- BitFenix Prodigy chassis
- Intel Core i7-3770K CPU, Overclocked at 4.4 GHz
- ASUS P8Z77-I Deluxe Z77 Motherboard
- EVGA GeForce GTX 680 2GB GPU
- OCZ 240GB Vertex 3 SSD
- Seagate 2TB SATA 6G HDD
- 8GB Crucual DDR3-1866 Memory
- Cooler Master 850 watt Silent Pro PSU
You'll also see a large, efficient Prolimatech cooler inside along with a Blu-ray burner and Windows 7 for a surprisingly reasonable $2100 price tag.
The BitFenix Prodigy chassis is a unique design that starts with sets of FiberFlex legs and handles surrounding the mini-ITX case. The minor flexibility of the legs absorbs sound and impact on the table while the handles work great for picking up the system for LAN events and the like. While at first I was worried about using them to support the weight of the rig, I had no problems and was assured by both BitFenix and by AVADirect it would withstand the torture.

Gigabyte Launches Three New Factory Overclocked Kepler GPUs
Subject: Graphics Cards | October 4, 2012 - 04:42 PM | Tim Verry
Tagged: nvidia, kepler, gtx 680, gtx 670, gtx 660 Ti, gigabyte, factory overclocked
Gigabyte is launching three new factory overclocked graphics cards featuring a Kepler GPU, custom PCB, and custom cooler. The factory overclocks are notable, but will cost you. Specifically, the company is producing versions of the GTX 660 Ti, GTX 670, and GTX 680.
The Gigabyte GV-N680OC-4GD takes the GTX 680 GPU, places it on a custom PCB, and pairs it with 4GB of GDDR5 memory. It features two 6-pin PCI-E power connectors, and Gigabyte’s Windforce X3 450W custom cooler using a triangular fin design that allegedly increases cooling potential. While the GDDR5 memory clockspeeds have not been increased over the reference clocks, the GPU core and boost clockspeeds have been pushed to 1071 MHz and 1137 MHz respectively. The following chart shows the differences in clockspeed and memory over the reference design.
| Reference GTX 680 | Gigabyte N680OC-4GD | |
| GPU Core | 1006 MHz | 1071 MHz |
| GPU Boost | 1058 MHz | 1137 MHz |
| GDDR5 Amount | 2 GB | 4 GB |
| GDDR5 Speed | 6 Gbps | 6 Gbps |
| Price | $500 | $800 (rumored) |
The GTX 680 is not the only card to get a custom makeover by Gigabyte, however. The GV-N670OC-4GD is a custom GTX 670. With this card, Gigabyte has set the base clockspeed at 980 MHz – the boost clockspeed of reference cards – and the boost clockspeed at 1058 MHz. Gigabyte has also doubled down on the GDDR5 memory by packing 4GB onto the custom PCB. The memory clockspeed remains the same 6 Gbps as reference cards, however.
This card uses the same Windforce X3 cooler as the cust GTX 680, and as a result has a triple slot design that looks identical to the N680OC-4GD. If you look just above the PCI-E connector though, you can see tell them apart by the product name.
| Reference GTX 670 | Gigabyte N670OC-4GD | |
| GPU Core | 915 MHz | 980 MHz |
| GPU Boost | 980 MHz | 1058 MHz |
| GDDR5 Amount | 2 GB | 4 GB |
| GDDR5 Speed | 6 Gbps | 6 Gbps |
| Price | $400 | $550 (rumored) |
Finally, we have the GV-N66TOC-3GD which overclocks the GTX 660 Ti GPU to the max. Factory clockspeeds are set at 1032 MHz base and 1111 MHz boost. Memory also sees a small bump from 2GB reference to 3GB. On the other hand, the memory is not overclocked and remains at the reference 6 Gbps clockspeed. This card also has a triple fan Windforce cooler, however this version is not the triple slot design found on the GTX 670 and GTX 680s SKUs – only dual slot.
| Reference GTX 660 Ti | Gigabyte N66TOC-3GD | |
| GPU Core | 915 MHz | 1032 MHz |
| GPU Boost | 980 MHz | 1111 MHz |
| GDDR5 Amount | 2 GB | 3 GB |
| GDDR5 Speed | 6 Gbps | 6 Gbps |
| Price | $300 | $415 (rumored) |
All three of the Gigabyte GPUs feature two DVI, one full-size HDMI, and one full-size DisplayPort connector for video outputs.
All three factory overclocked graphics cards feature respectable GPU overclocks, and it appears that Gigabyte has provided ample cooling for each GPU. The triple slot, triple fan version on the N670OC-4GD and N680OC-4GD in particular seem to offer headroom above even what Gigabyte has clocked these out of the box. Curiously though, Gigabyte is continuing the trend of not touching the memory clockspeed of Kepler cards. It may be that the RAM chips are already at their max on the reference design, or there could be some behind the scenes talk with NVIDIA not waning Add In Board partners to touch the memory Unfortunately, all I have at this point is speculation, but it is a rather curious omission on such high end cards. That point becomes clearer when price is taken into consideration. Videocardz claims to have the pricing information for the three video cards, and the custom cards are going to cost you a large premium over reference cards. The rumored prices can be found in the charts above compared against the reference pricing, but the basic run down is that the GV-N66TOC-3GD will cost $415, the GV-N670OC-4GD will cost $550, and the GV-N680OC-4GD will cost (an astounding) $800.
I’m hoping that the rumored prices are in error and will be adjusted once the cards are available. These are neat cards that look to have plenty of cooling, but I’m still trying to figure out just what these cards have to offer to justify the huge jump over reference pricing. And, no, the superfluous gold plated HDMI connectors do not count. [For example, the 4GB Galaxy GTX 670 we recently reviewed was only $70 over reference while the Gigabyte card is rumored to be $150!]

PhysX Settings Comparison
Borderlands 2 is a hell of a game; we actually ran a 4+ hour live event on launch day to celebrate its release and played it after our podcast that week as well. When big PC releases occur we usually like to take a look at performance of the game on a few graphics cards as well to see how NVIDIA and AMD cards stack up. Interestingly, for this title, PhysX technology was brought up again and NVIDIA was widely pushing it as a great example of implementation of the GPU-accelerated physics engine.
What you may find unique in Borderlands 2 is that the game actually allows you to enabled PhysX features at Low, Medium and High settings, with either NVIDIA or AMD Radeon graphics cards installed in your system. In past titles, like Batman: Arkham City and Mafia II, PhysX was only able to be enabled (or at least at higher settings) if you had an NVIDIA card. Many gamers that used AMD cards saw this as a slight and we tended to agree. But since we could enable it with a Radeon card installed, we were curious to see what the results would be.
Of course, don't expect the PhysX effects to be able to utilize the Radeon GPU for acceleration...
Borderlands 2 PhysX Settings Comparison
The first thing we wanted to learn was just how much difference you would see by moving from Low (the lowest setting, there is no "off") to Medium and then to High. The effects were identical on both AMD and NVIDIA cards and we made a short video here to demonstrate the changes in settings.

Maingear Launches New Alpha 24 Super Stock All In One PC
Subject: Systems | September 26, 2012 - 09:00 AM | Tim Verry
Tagged: synergy, maingear, Ivy Bridge, gtx 680, cablecard, AIO
Custom PC manufacturer Maingear took the wraps off of its latest all in one computer today, and it features some impressive specifications for an AiO system. As the release of Microsoft’s upcoming Windows 8 operating system approaches, Maingear is gearing up support by introducing a system with desktop specifications and a large 24” touchscreen display with the new Alpha 24 Super Stock.
On the outside, the matte black Alpha 24 all in one has a prominent 24” glossy touchscreen display running at 1920x1080 resolution. Above the screen is a webcam. There are ports along the left side of the bezel and ventilation slits for the HSF on the back.
What makes the Alpha 24 interesting is all the hardware that the company has managed to pack inside the monitor-sized form factor. Internally, you will find a mini-ITX motherboard with Intel Core i7 3770K Ivy Bridge processor, and up to 16GB of DDR3 laptop RAM, 256GB Crucial M4 mSATA SSD, 3TB mechanical hard drive, and a NVIDIA GeForce GTX 680 graphics card (GTX 650 and GTX 670 GPUs are also options). The Alpha 24 also features 802.11n Wi-Fi and Bluetooth support, with an optional Bigfoot Killer Wireless add-on card. Not bad at all for an all in one system!
Maingear is further pushing the multimedia and home theater PC aspects of the Alpha 24. An internal DVD or Blu-ray optical drive can be added, for example. Also interesting is the inclusion of an optional CableCARD tuner that will allow the Alpha 24 to tune into encrypted cable TV stations and act as a DVR using software like Windows Media Center. Unforunately, details on the specific tuner they are offering were not given in the press release. The Alpha 24 can also act as a monitor for external video sources connected over HDMI, such as a game console or another computer.
Maingear did not skimp on the I/O either for the claimed “no compromises” Alpha 24. Internal expansion slots include two mini PCI-E and one PCI-E x16 slot (for the GPU). External connectivity options include three USB 2.0 ports, a SD card reader, mic in/audio out jacks, and space for a single slim optical disc drive along the right edge of the display. Ports along the left edge of the display include the graphics card's video outputs – 1x DVI, 1x HDMI, 2x DisplayPort – two S-Video connectors, power jack, Gigabit LAN, HDMI output, two USB 2.0, two USB 3.0, optical audio output, and analog audio jack. The back of the Alpha 24 hosts a VGA and HDMI input along with antenna connectors.
Also, the internals are user serviceable and things like the GPU can easily be upgraded, according to the company – allowing for future upgrading to keep the system relevant. Maingear CEO Wallace Santos stated the following in the company's press release.
“In this day and age, there shouldn’t be a reason anyone would need to compromise for an all-in-one performance PC. Other all-in-one PC solutions pale in comparison to the ALPHA 24 and can be summed up with just a few words: 1080p gaming set to Ultra, maxed anti-aliasing and tessellation.”
Currently, the Alpha 24 has an MSRP starting at $1,349 for the base model. It will ship with Windows 7 x64, however it should be available pre-loaded with Windows 8 later next month following the Windows 8 release.
All in all, the Maingear Alpha 24 looks like a decent computer for the price, though you are paying a bit of a premium for the all in one form factor versus going with a traditional desktop – and building a PC yourself by following the PC Perspective Hardware Leaderboard. So long as the reviews come back stating that build quality is good, it is definitely an interesting machine if you are limited to OEM options and don’t want a tower sitting under your desk – the CableCARD tuner option is also a nice touch.
You can find more photos of the Alpha 24 over at the Maingear website.
What do you think about this system, enough future upgrade-ability to sway you away from a traditional tower PC?
ASUS Mars III Dual GTX 680 Graphics Card Pictured, Set to Launch Soon
Subject: Graphics Cards | August 28, 2012 - 07:31 PM | Tim Verry
Tagged: triple fan, nvidia, mars 3, gtx 680, dual gpu, custom cooler, asus
If rumors hold true, NVIDIA’s GTX 690 will soon be joined by a custom dual GTX 680 card from ASUS. First shown off at Computex, the Mars III combines two GTX 680 graphics chips, 8GB RAM, and a massive triple fan cooler. Expect it to cost quite a bit but offer up some impressive performance numbers.
Update: According to ASUS speaking with TechPowerUp, this card is not going to be released to the public after all. I suppose the Powercolor 7990 Devil 13 will have to suffice!
ASUS has a long history of taking high-end graphics chips to the extreme, even going so far as to put more than one graphics processor on the same PCB. The third iteration of its custom dual GPU "MARS" series graphics cards, the MARS III was first shown off at Computex. At the time, the company indicated that the dual NVIDIA GPU card was not quite ready for final release as the GPU cooling solution and PCB in particular required further tweaking.
Going by the recently leaked photos, ASUS has been hard at work refining the custom design, and it certainly looks ready for prime time. The MARS III takes two Kepler architecture-based GTX 680 GPUs, beefed up power phases, and a total of 32 RAM chips (8 per GPU) for 8GB of total RAM, and places it on a single black PCB. Further, the two GTX 680 GPUs are configured in SLI using a PLX PEX8747 bridge chip. While it does not have more CUDA cores than the NVIDIA reference GTX 690 (which we recently reviewed), it should have a bit more overclocking headroom in addition to the extra 4GB of GDDR5 memory. I would expect that it will cost more than the GTX 690 as a result of its custom design and extra memory, but so far there is no word on what that price might be.
Needless to say, all that hardware is going to require a lot of power. Internally, each GPU will be fed electricity using an 8+2 power phase. Further, the board continues to feature the three 8-pin PCI-E power connectors which allows the dual-GPU graphics card to draw up to 525 Watts of power. While the color of the cooler has been changed from the model seen at Computex to a red and black color scheme, the red overclocking button is still there on the side of the card. It will spin the fans up to 100% to allow you to push the NVIDIA GPUs as far as possible.
Video outputs include three DVI and a single mini-DisplayPort connector for NVIDIA Surround gaming and a fourth accessory monitor.
The dual GTX 680 graphics card at Computex.
Sources speaking with Videocardz have confirmed that the card is nearly ready for retail availability, and is only waiting NVIDIA’s go ahead.
Now that the rumored 7990 is on the way (or at least a custom version of the 7990), I would bet that we will be seeing this custom ASUS card sooner rather than later – and that NVIDIA’s “okay” to unleash this beastly graphics card should not be difficult to get.
Have you been following the ASUS Mars III? You can find more Mars III coverage and photos by following the Mars III tag. Further, you can see more leaked photos over at Videocardz.
[Now if you’ll excuse me, I need to clean the drool off of my desk.]
How fast can Lightning go? Testing out the LN2 BIOS on the MSI GTX680
Subject: Graphics Cards | August 3, 2012 - 05:42 PM | Jeremy Hellstrom
Tagged: MSI GTX680 Lightning, LN2 BIOS, factory overclocked, gtx 680, MSI Afterburner, overvolting
[H]ard|OCP recently tested the highly overclocked MSI GTX 680 Lightning, but because of the new release of the MSI Afterburner 2.2.3 tool they decided to retest to see if the new Afterburner will raise the ceiling on their maximum overclock. This new version allows voltage control of the GPU, the memory, and the PLL which ought to help push the card to higher frequencies. That did certainly turn out to be the case as they saw noticeable increases to all of the clocks on the card and more importantly translated into improvements in game play. When they used the LN2 BIOS the improvements were even more impressive. Remember that volt modding will shorten the lifespan of the card, but what a life it will have while it survives.
"Today we are revisiting the MSI GeForce GTX 680 Lightning video card. with its long-promised GPU and RAM voltage tweaking Afterburner software. We test both the stock BIOS and "LN2 BIOS" to find the best possible gaming experience the Lightning has to offer, and determine if the performance justifies the price."

Due to popular request, I am going to try to keep our readers up to date on the current availability of graphics cards and pricing on the market. With the recent price drops from AMD, the frequent out-of-stock status of the GTX 680 cards and the release of the GTX 670, I thought this would be a great summary of the current situation.
AMD's Radeon HD 7970 GHz Edition 3GB
We will try to post new updates weekly or maybe more frequently as we see fit. Newegg is our partner of choice for this today, so let's see what we have.

GeForce GTX 670 2GB - In Stock
Starting at $399
In a stunning change of fate, the NVIDIA GeForce GTX 680 has been steadily in stock for the last few weeks but the Radeon HD 7970 GHz Edition that we reviewed on June 24th has yet to show its face. Yes, you can find HD 7970 cards running at 1000 MHz core clock speeds (and higher) though they don't have the 6.0 Gbps memory speeds nor the "PowerTune with Boost" technology that really set the new version of the GPU apart.
When asked, AMD told us to expect Sapphire and XFX models in stock early next week - so we'll definitely keep an eye on the online retailers for that.
The only other changes are some more price drops on the AMD side. You can now get a standard HD 7970 for $80 less than the GeForce GTX 680 and the Radeon HD 7950 for $50 less than the GTX 670. AMD knows that with NVIDIA's great branding and marketing they needed to make a case for their GPUs over the competition and these types of price cuts really give gamers two great options for their gaming dollar.
We are still waiting on NVIDIA's answer for sub-$399 GPUs based on Kepler - hopefully we won't be waiting long.
