GIGABYTE GTX 780 GHz Edition Video Card Review
The GIGABYTE GTX 780 GHz Edition video card has the fastest factory Boost Clock of all GTX 780 video cards on the market. It performs at 1072MHz out-of-box, and even faster frequencies in-game. We continue pushing its overclock, and compare it to an AMD Radeon R9 290. The GIGABYTE GTX 780 GHz Edition just might be the video card for you.

Overclocked R9 290 Apples to Apples Testing
In this section of our evaluation we will be comparing the overclocked GIGABYTE GTX 780 GHz Edition directly with the overclocked AMD Radeon R9 290 video card. Remember, our GIGABYTE GTX 780 GHz Edition has been overclocked to 1090MHz base clock, with the boost clock at 1142MHz. This results in a real-world frequency of 1267MHz. The memory was also overclocked to 1602MHz or 6.4GHz GDDR5.

Overclocking the AMD Radeon R9 290 is a relatively simple, however still a somewhat new process. Instead of having direct control of the video cards operating frequency we now decide on a few factors. These are the Power Limit setting, the GPU clock setting, and the memory clock setting. These are all percentage based.
First we increased power limit to its highest value of 50%. We did not realize any negative effects to running this high of a power limit, as to running 30% for instance. This assured maximum power should the need for it arise. This allowed us to increase the GPU clock setting to 14%. This increased the Radeon R9 290's default clock from 947MHz to 1080MHz. We also found that an additional 10% on the memory brought the frequency up to 1375MHz or 5.5GHz GDDR5.
The purpose of this comparison is to directly compare the GIGABYTE GTX 780 GHz Edition with the overclocked R9 290 to determine if the R9 290's overclock makes it the better value as far as performance for price is concerned.
Keep in mind this is a reference AMD Radeon R9 290, we do not have any custom retail cards yet.
Battlefield 4
In this comparison in Battlefield 4 we are comparing at 2560x1600 with 2X MSAA and "Ultra" settings enabled.

In our Battlefield 4 performance testing we discovered the stock Radeon R9 290 was only playable at 2560x1600 when using FXAA "Low" as our AA setting. Here, we see that the overclock brought its performance up to 58.5 FPS at these settings. This is more or less playable by our standards. It is just shy of 58.5, however the gameplay was not as jumpy as it was before. The overclocked GIGABYTE GTX 780 GHz Edition averaged 64.7 FPS at these settings. This is 10.6% faster than the overclocked Radeon R9 290.
Tomb Raider
In Tomb Raider we are comparing at 2560x1600 with FXAA and "Ultra" settings and "TressFX" enabled.

The AMD Radeon R9 290 performed more admirably after receiving its overclock. It averaged 54 FPS at these settings. It does not receive as large of a performance charge for playing with TressFX hair as the GIGABYTE GTX 780 GHz Edition because it is an AMD based GPU. Still, the overclocked GIGABYTE GTX 780 GHz Edition was 3.7% faster and averaged 56 FPS. In terms of gameplay, the two were very similar. The slight performance advantage did not really change the scope of the two gameplay experiences.![]()
Crysis 3
In this test we have Crysis 3 configured to operate at 2560x1600 with 2TX SMAA and "Very High" settings enabled.

We found that the overclock did enough to allow our GIGABYTE GTX 780 GHz Edition to enable "Very High" settings in Crysis 3. It averaged 44.4 FPS with these settings. This is 7.2% faster than the overclocked AMD Radeon R9 290 which averaged 41.4 FPS. The overclock was not enough to provide playable gameplay at these settings, however it did provide a noticeable performance gain compared to its stock performance.![]()
Far Cry 3
In our first test in Far Cry 3 we are comparing at 2560x1600 with 4X MSAA and "Ultra" settings enabled.

Our overclocked GIGABYTE GTX 780 GHz Edition delivered the better performance of these two video cards at these settings. It averaged 43 FPS which we determined was playable. This performance is 13.2% faster than the AMD Radeon R9 290, which averaged 38 FPS. Unfortunately for the Radeon R9 290, the overclock was not enough for it to perform at our desirable rate of play.![]()
Overclocked GIGABYTE GTX 780 GHz Edition vs. Overclocked Radeon R9 290
The first thing we are going to discuss about overclocking these two video cards was the relative ease of each. The GIGABYTE GTX 780 GHz Edition was the easier of the two. With OC GURU II we were quickly able to increase our power target and voltages, and begin increasing our clock speed. What makes the Radeon R9 290 more difficult to overclock, is that it uses a percentage based system. Instead of setting it to run at 1090MHz, you have to find the correct percentage that will provide that frequency.
Second, the biggest difference that we saw between these two video cards were the power, temperature, and fan noise. The overclocked GIGABYTE GTX 780 GHz Edition remained exclusively cool in temperature, only increasing to 67c under load. The AMD Radeon R9 290 ran at 95c under load. This makes a huge difference in terms of ambient heat in your case, plus we feel better knowing our hardware is constantly dissipating heat with the WINDFORCE 3X 450W cooling system supplied on the GIGABYTE GTX 780 GHz Edition. Power draw was considerably higher on the Radeon R9 290, when overclocked it drew 484W compared to 428W on the GIGABYTE GTX 780 GHz Edition.
Last is the performance increase experienced from overclocking the video cards, and how these compete against each other. We found that the GIGABYTE GTX 780 GHz Edition's overclock was more valuable. Throughout this evaluation we found instances where it allowed higher levels of AA, or higher quality graphics in game. The Radeon R9 290's overclock did a good job of narrowing the performance gap between the two video cards, however it still performed noticeably slower compared to the GIGABYTE GTX 780 GHz Edition.

During our evaluation of the GIGABYTE GTX 780 GHz Edition video card, we have come to enjoy and respect the performance level available in today's most demanding games. Architecturally the GIGABYTE GTX 780 GHz Edition is a solid video card. The metal back plate and metal fan housing provide the necessary security of our investment, without looking bulky or unattractive. The WINDFORCE 3X 450W cooling system provides guaranteed heat dissipation up to 450W of power, and we saw much lower power consumption than the competition while remaining at a higher level of play.
One of the finer selling points of the GIGABYTE GTX 780 GHz Edition is that it is the fastest clocked GeForce GTX 780 video card on the market, being sold via retail. It's base clock of 1020MHz and boost clock of 1072MHz generate enough performance for the GIGABYTE GTX 780 GHz Edition to outperform a closely priced Radeon R9 290. In fact, in none of our tests did the AMD Radeon R9 290 outperform the GIGABYTE GTX 780 GHz Edition.
The GIGABYTE GTX 780 GHz Edition is currently available at the price of $499.99 after $10 MIR. Purchasing this video card assures users the fastest out-of-box overclock on a GTX 780 GPU. While it already has this overclock, with OC GURU II you can push its limits even farther. You do pay a premium compared to other GeForce GTX 780 video cards, however it may be worth it for the guaranteed clock speeds and performance therein.
A good review and comparison for those considering a new top end GPU.
