MSI Gaming N780 TF 3GD5/OC GeForce GTX 780 Introduction:

The GTX 780 brought another layer of performance to the high end gamers while fleshing out NVIDIA's GTX performance stack with a card that clearly set the bar high for AMD with its next launch. Price wise it came in at about $350 less than the fastest single GPU card out, the GTX Titan, with performance that came very close to matching that of the GTX Titan. When the GTX 770 launched, NVIDIA's partners, MSI included, were set and ready to deliver in-house built products using their exclusive design philosophies. The result of that launch for MSI was the Gaming series N770 TF 2GD5/OC GTX 770. With the GTX 780, MSI had a small lag in that availability but soon after launched the card I am looking at today: the Gaming N780 TF 3GD5/OC GeForce GTX 780.

Packed full of MSI's best design philosophies and tools, the Gaming series GTX 780 features Military Class IV build components that meet MIL-STD-810G. You get Tantalum core Hi-C caps, new SFC Chokes, solid aluminum core capacitors, and MSI's own revised Twin Frozr IV cooling solution. Along with the build components, MSI raises the base core clock and GPU 2.0 Boost clocks to 954MHz/1006MHz, respectively, for added gaming performance out of the box. Included in this package is MSI's Afterburner overclocking and tuning utility that comes with Predator, a screen capture and recording utility that adds value by saving you a few bucks. For its Gaming series GPUs, MSI has put together a much simpler utility for the masses that prefer the install and go mindset. Called Gaming App, this utility lets the user flip between three modes without having to know what settings to change. Sweet and simple.

So where does all this feed into and what does it mean? MSI has put a focus on the gamer with its "G.A.M.E." spirit. Priced right at just $20 over the reference version's $649, it includes the game Splinter Cell: Blacklist again as an added value. Let's see if the philosophy holds up under some gaming tests to see if MSI has brought enough to the table.

MSI Gaming N780 TF 3GD5/OC GeForce GTX 780 Closer Look:

MSI has gone through a dramatic shift in its messaging to the consumer. The graphics on the packaging illustrate this and set MSI apart from its competitors on store shelves. The front panel features a large tribal dragon that represents MSI's Game Spirit philosophy. At the bottom right an icon shows that this is a factory overclocked model of the MSI GTX 780. At the top right is the Gaming series logo that lets you know this card is equipped with an extensive set of features, including MSI's Twin Frozr IV cooling solution. The back panel goes into detail on the Gaming specific feature set, including MSI's own Gaming App, Military Class IV technology, the Twin Frozr advanced cooling solution, and NVIDIA-specific feature set.

 

 

 

 

 

 

 

 

 

 

 

Inside the sleeve is a black box that carries the dark theme through to the internal packaging. Inside are two levels; one that holds the accessory bundle documentation and hardware, while the lower level holds the card deep in an open cell foam cushion. The accessory bundle that comes with the MSI N780 TF 3GD5/OC includes a quick installation guide, driver and utility disk, 6-pin to 8-pin PEG connector, and a dual 4-pin molex to 6-pin PEG connector. A pretty slim bundle, but with a card like this you most likely are not going to need adapters for your monitor(s) or even use the power adapters.

 

 

Packaging, check; bundle, check; card, nope not yet. After looking at the GTX 770 Gaming I found that MSI put together an excellent card that runs cool and overclocks well based on the design of the card. Let's dig into what MSI has put together with the N780 TF 3GD5/OC.

MSI Gaming N780 TF 3GD5/OC GeForce GTX 780 Closer Look:

As we saw with the GTX 770 Gaming series card, the GTX 780 is a great looking card that should look right at home in any of the red and black themed boards on the market, including MSI's own Z87-GD65. Equipped with large 100mm PWM-controlled propeller blade technology fans, the GTX 780 should handle any cooling situation. What you get with MSI's GTX 780 Gaming series card is a custom PCB built for use with NVIDIA's GK110 core. The back side of the PCB does not have much of interest, but you get a couple Hi-C caps right under the core to provide some added core voltage stability. Looking at the top and bottom views of the GTX 780 Gaming we can see that the dual slot Twin Frozr IV cooling solution uses a total of five heat pipes to carry the thermal load from the core to the aluminum fin array. Four are 6mm in size and come out the bottom side of the heat sink, while a single larger 8mm heat pipe pops out of the top side looping back into the aluminum fin array. MSI's GTX 780 Gaming is designed for use in a 16x PCIe 3.0 slot on a supporting motherboard but is backwards compatible to earlier standards. Size wise the GTX 780 Gaming is 10.25 inches in length allowing for fitment in just about any chassis on the market.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Display connectivity on the MSI Gaming N780 TF 3GD5/OC is standard fare for Kepler architecture-based video cards with a single Dual Link DVI-D, Dual Link DVI-I, HDMI 1.4a port, and a full size DisplayPort. A 3+1 display configuration is supported using the available display outputs. Surround gaming is supported on a single card while adding a 3D Vision system for 3D Surround will mean you are going to have to add another GTX 780 in SLI to really enjoy the experience. MSI ships the card with plugs and covers to prevent dust or debris buildup on the un-used connection points. The I/O mounting bracket supports discharging the thermal load outside the chassis but the design of the Twin Frozr IV cooling solution is going to dictate that most of the thermal load is going to go inside the chassis. The good thing is that most newer chassis have a way to compensate for this with improved airflow. The back end of the card is wide open allowing the thermal load out from under the shroud and into the chassis' airstream.

 

 

A pair of SLI bridge connections hints at the SLI support for this card, running up to four cards in a motherboard that supports the technology. Along the spine of the PCB and under the Twin Frozr IV heat sink runs an aluminum brace and heat sink used to stiffen the PCB as well as cool the memory modules under the main heat sink. Power for the MSI GTX 780 Gaming is supplied by a single 6-pin and single 8-pin PCIe power connectors. A 600 watt power supply is going to be recommended to handle the 229 watt TDP on this card. Factory overclocked and cooled it carries the same operating TDP as the reference version.

 

 

Once you pull Twin Frozr IV cooling solution off of the PCB, an aluminum PCB support/memory cooler is visible. Its purpose is to both improve structural rigidity and function as additional cooling for the memory modules and Military Class IV power circuitry. A black PCB is used on this card and meshes nicely with the design. Once the PCB support/memory cooler is removed, the power supply layout on the PCB is clearly visible. MSI uses its Military Class IV components selection that includes solid aluminum capacitors (ten year increase in longevity), new Super Ferrite chokes (SFC 30% power handling increase), and tantalum core Hi-C caps (stabilize power delivery). This construction philosophy is meant to improve efficiency, longevity, and the current handling capabilities to drive increased overclocking potential. Towards the rear of the PCB is a small riser that holds the ON Semi-conducter NCP4206 voltage controller used to manage the power phases on this card.

 

 

 

One of the main features of the MSI GTX 780 Gaming is the Twin Frozr IV cooling solution. Its advanced thermal design is one of the hallmarks of the GAME philosophy that MSI strives to deliver to gamers who want to just put the card in the system and start fraggin'. A cursory view shows the five heat pipe design on this fourth generation of the Twin Frozr design. It uses a total of five (four x 6mm + one x 8mm) heat pipes in a direct contact design that delivers the thermal load to the large aluminum fin array. The fin array is where MSI spent some design time by using air diverters to direct the airflow through as much of the fin array as possible so that it spends more time in the heat sink, presumably to increase the thermal transfer and cooling efficiency. After my testing this technology seems to work well with such a thin fin array. The contact surface is flat and makes great contact with the large GK110 die.

 

 

Airflow through the dual slot Twin Frozr cooling solution is provided by a pair of 100mm PWM-controlled propeller blade fans. Using this type of fan is needed to push the higher static pressure needs of the heat sink. Noise characteristics of these fans at stock speeds are great. For the most part these fans are dead silent when controlled by the GPU and NVIDIA's latest fan control algorithms. When ramped up they are still relatively quiet by comparison to the already muffled reference cooling solution. This part of the advanced thermal design concept is another check mark for gamers and power users alike. You get a cool, quiet, high performance discrete GPU. Each of the fans mounts to the shroud instead of the heat sink as I have seen on some cards. Not that one is better than the other.

 

 

MSI is using the latest iteration of the 28nm GK110 core that houses 7.1 billion transistors. On the GTX 780 we get four or five Graphics Processing Clusters, 12 SMX with 192 CUDA cores that takes us up to the 2304 core count, 1.5MB of shared L2 cache, 198 Texture units, 48 ROPs, and a drop to 3GB of GDDR5 memory running through the still new 6x64-bit (384-bit) bus. Clock speeds are set dynamically based on how GPU Boost 2.0 manages the thermals and power windows. Out of the box we see a base core clock of 954MHz on the 2304 CUDA cores with a boost clock of 1006Mhz or higher on the core with 1502MHz on the GDDR5 memory. Samsung supplies the 3GB of frame buffer on the MSI GTX 780 although the exact IC is difficult to identify.

 

 

After seeing what the GTX 770 Gaming was capable of I am anticipating that the GTX 780 Gaming will perform similarly across the board.

MSI Gaming N780 TF 3GD5/OC GeForce GTX 780 Testing:

Testing of the MSI N780 TF 3GD5/OC GeForce GTX 780 will consist of running it and comparison cards through the OverclockersClub.com suite of games and synthetic benchmarks. This will test the performance against many popular competitors. Comparisons will be made to cards of a range of capabilities to show where each card falls on the performance ladder. The games used are some of today's newest and most popular titles, which should be able to provide an idea of how the cards perform relative to each other.

The system specifications will remain the same throughout the testing. No adjustments will be made to the respective control panels during the testing to approximate the performance the end user can expect with a stock driver installation. I will first test the cards at stock speeds, and then overclocked to see the effects of an increase in clock speed. The cards will be placed in order from highest to lowest performance in each graph to show where they fall by comparison. The NVIDIA comparison cards will be using the 320.18 drivers while AMD-based cards will be using the Catalyst 13.5 beta 2 drivers and latest CAP profile. The results generated in my testing reached by utilizing the latest FCAT tools to illustrate the true picture of the gaming experience. To do so will require a second PC setup to capture the data stream generated by the compared video cards.

Overclocking:

Overclocking on NVIDIA's Kepler-based GPUs takes advantage of GPU Boost 2.0 technology to deliver clock speeds that are limited not only by the maximum possible clock speed the core can run but by both a thermal and power envelope. NVIDIA found out that the Kepler GPU was not reaching its thermal limits, leaving clock speed on the table. Now we have a little bit of both to look after. By maximizing these two sliders in MSI's Afterburner GPU overclocking and tuning utility you get the best chance at reaching the max clock your card can do on air. Second on the list was to increase the fan speed to max while advancing the core voltage slider to the maximum limit of +37mv. Boosting the core clock up in 50MHz increments got me close to the final core speed of 1189MHz or a +151MHz offset under boost and in game; an 183MHz boost over the factory boost clock speed. Stock memory speed on the 3GB of GDDR5 memory is 1502MHz or an 6008MHz effective memory speed. Boosting up the memory speed in +100MHz increments gave me a final memory clock speed of 1722MHz or a 6890MHz effective clock speed. Pretty decent numbers from this card. The core seemed a bit weak and did not quite reach 1200MHz but still offered up a nice bonus in clock speed.

Manually tuning will allow you to reach as high a clock speed as the hardware will allow. MSI's Afterburner utility is a great tool for this but MSI offers other options with its Gaming app. This lightweight tool gives the user the flexibility of running the MSI GTX 780 Gaming in three separate modes at the click of a button. OC Mode offers a 1071MHz boost clock, gaming mode drives the boost clock speed to 1019MHz, while silent drops it down to 980MHz. Changing between these modes was easy and did not result in any crashes. Afterburner can sport a new look to show your true gaming spirit with a special skin put together that mirrors the look and feel of the packaging and Gaming Spirit branding. I can say it looks much better than the standard green theme.

 

 

 

Maximum Clock Speeds:

Testing for the maximum clock speed consisted of looping Unigine Heaven 4.0 for 30 minutes each to see where the clock speeds failed when pushed. If the clock speed adjustment failed, then the clock speeds and tests were rerun until they passed a full hour of testing.

MSI's GTX 780 Gaming is the second fastest card in each one of the tests. The margins over the reference card are not great at stock speeds but in all aspects it is faster. The lower overclock on the core impacts overall scoring but the higher memory speed allows the MSI card to stay on top of the reference card during the overclocked testing.

MSI Gaming N780 TF 3GD5/OC GeForce GTX 780 Testing:

Temperature testing will be accomplished by loading the video card to 100% using Unigine's Heaven Benchmark Version 4.0, with MSI's Afterburner overclocking utility for temperature monitoring. I will be using a resolution of 1920x1200 using 8xAA and a five-run sequence to run the test, ensuring that the maximum thermal threshold is reached. The fan speed will be left in the control of the driver package and video card's BIOS for the stock load test, with the fan moved to 100% to see the best possible cooling scenario for the overclocked load test. The idle test will involve a 20-minute cool-down, with the fan speeds left on automatic in the stock speed testing and bumped up to 100% when running overclocked.

MSI's Twin Frozr IV dual fan lower profile cooling solution does an excellent job of keeping temperatures in check. At stock (factory overclocked) speeds it delivers the lowest idle temperatures in the comparison field and is nine degrees cooler than the reference card under load. The factory cooling solution on the GTX 780 is fairly robust and is able to stay within a degree of the Twin Frozr IV solution when overclocked.

MSI Gaming N780 TF 3GD5/OC GeForce GTX 780 Testing:

Power consumption of the system will be measured at both idle and loaded states, taking into account the peak voltage of the system with each video card installed. I will use Unigine's Heaven Benchmark version 4.0 to put a load onto the GPU using the settings below. A 15-minute load test will be used to heat up the GPU, with the highest measured temperature recorded as the result. The idle results will be measured after 15 minutes of inactivity on the system. With dual-GPU setups, the two core temperatures will be averaged.

Idle power consumption on the MSI GTX 780 Gaming was similar to the reference GTX 780 and GTX Titan. Under load MSI's version used slightly more power than the reference card. Overclocked the margin between the reference and MSI cards' current load increases due to a higher over voltage and the use of a pair of fans instead of the single blower style fan.

MSI Gaming N780 TF 3GD5/OC GeForce GTX 780 Conclusion:

After looking at the reference GTX 780 and seeing that it delivered performance close to that of the NVIDIA GTX Titan, the expectations were high for this card going into the testing. Compared to the reference card, the MSI Gaming N780 TF 3GD5/OC GeForce GTX 780 raised the bar a bit with small margins over the reference card across the entire suite of games at both 1920x1080 and 5760x1080. Overclocking brings performance gains across the board. This particular sample did not overclock as high as I would have wanted on the core with a GPU Boost 2.0 maximum boost clock of 1189MHz. Above 1189MHz it would not pass all of my stability tests, but could pass some as high as 1215MHz; even though it operated below the power and thermal thresholds. The GDDR5 memory, on the other hand, soared all the way up to 1722MHz, well above the reference card in the comparison field.

That give and take ended up with some solid results in 3DMark. For the experienced user, overclocking via MSI's own Afterburner utility is available. It includes Predator, a frame capture utility that can save you a bit of coin over paying for a utility. On the flip side MSI includes its Gaming App that feature three different clock speed levels for one touch over / underclocking. It's as easy to use as MSI's OC Genie on its motherboards. Make it simple and they will use it to effect.

What makes all that overclocking possible is the fact that MSI has a custom PCB and its Military Class IV components, including Super Ferrite Chokes, tantalum core Hi-C caps, and solid aluminum capacitors that improve efficiency, stability, and longevity, topped off with the latest iteration of the Twin Frozr cooling solution. When running the Gaming series GTX 780 at stock speeds, the Twin Frozr IV cooling solution yielded core temperatures of nine degrees or almost 12% cooler than the reference card. All thanks to the 100mm propeller blade fans and special air diverters used in the heat sink assembly. Maxing out the fan speeds, though, results in this margin almost disappearing completely with a one degree difference. While both the reference and MSI cards are quiet at stock speeds thanks to NVIDIA's newest fan speed management algorithms, MSI's Twin Frozr-equipped solution is quieter both managed manually and by the card's hardware.

As an NVIDIA card you get the whole of the NVIDIA ecosystem and can actually use it with a single card if you so choose. SLI, Surround, 3DVision with a compatible 3D ready 120Hz monitor, built-in H.264 encoding, and so much more. The release of NVIDIA's GeForce Experience ensures you get the latest drivers and game settings for the games you play.

Priced currently at $669 from online e-tailers, you pay a $20 premium for the privilege of owning the MSI Gaming N780 TF 3GD5/OC GeForce GTX 780. All told the latest gaming series card from MSI delivers excellent FPS performance while running cool and quiet. It does not get much better unless you lay down another $350 US.
