We check out the overclocking capabilities of the GeForce GTX Titan using EVGA Precision X utility in maximum power level and temperature:

To ensure the cooling process, we remove the front panel of the PC case and leave the fans of the Titan running with its maximum speed of 4,000 RPM.

After many hours of the testing process, we try to increase the clock speed of the GPU to about 135 MHz and the memory frequency ranges T 1,300 MHz.

The clock speed obtained 927/1011/7308 MHz.

However, we had to gradually reduce the graphics memory frequency to about 40 MHz (also 7,268 MHz) to prolong the testing process. The frequency of the GPU was overclocked card can sometimes reach 1,137 MHz, but always fell to 1,071 MHz to transmit data at a high level.

As you can see, the GPU works very comfortably with the GK 110 placed under our conditions, its temperature does not exceed 640C. Our efforts to overclock it at 1,187 volts voltage were unsuccessful, so we stopped at the clock speeds as mentioned above.

Power consumption

We measure the energy consumption during our test equipment with different graphics cards using the multifunctional Zalman ZM-MFC3, which can report the power consumption of a computer (without monitor). There are two test modes: 2D (text editing in Microsoft Word or web surfing) and 3D (4 attempts in the opening scene Crysis 3 with 2560x1440 resolution is to install the highest quality image, but no MSAA). Our test indicates that the new game has greater opening magnitude than the previous times using Metro 2033: The Last Refuge, which is why we chose to replace it.

For the purposes of this comparison we added the results of the Nvidia GeForce GTX 690, ASUS GeForce GTX 680 DirectCU II TOP and HIS 7970 X2 ICEQ GHz Edition 3 GB. Let's see if we get something:

Energy consumption results

Energy consumption results

When the GeForce GTX Titan operates at clock speeds of its default, the system needs more than 55 to 60 watts compared to the ASUS GeForce GTX 680 and 44 to 45 watts compared to the HIS Radeon HD 7970. When the Titan is overclocked, the power consumption increased from 25 to 547 watts, not much for a configuration with a high-end graphics card. In fact, the results for the system processor of the Nvidia GeForce GTX 690 sometimes are just less than 50 watts. So there is nothing surprising here.

The configuration of all the graphics is comparable with each other, considering the low idle mode energy consumption of them is.

Configure and test methods

All graphics cards involved will be tested in a standard system with the following configurations:

·         Motherboard: Intel Siler DX79SI (Intel X79 Express, LGA 2011, BIOS 0494)

·         CPU: Intel Core i7-3960X Extreme Edition 3.3 GHz, 1.2 V, 6 x 256 KB L2, 15 MB L3 (Sandy Bridge-E, C1, 32nm)

·         CPU Cooling Fan: Phanteks PH-TC 14PE (2 x 135 mm fans at 900 RPM)

·         The surface cooling: ARCTIC MX-4

·         Graphics card: Nvidia GeForce GTX 690 2 x 2 GB, ASUS GeForce GTX 680 DirectCU II TOP 2 GB, HIS 7970 X2 ICEQ GHz Edition 3 GB

·         System Memory: 4 x 4GB DDR3 Mushkin Redline (Spec: 2133 MHz / 9-11-10-28 / 1.65 V)

·         System Hard Disk: Crucial m4 256 GB SSD (SATA-III, CT256M4SSD2, BIOS v0009)

·         Drive: for programs and games: Western Digital VelociRaptor (300GB, SATA-II, 10,000 RPM, 16MB cache, NCQ) inside Scythe Quiet Drive 3.5 "HDD silencer and cooler

·         Backup Drive: Samsung EcoGreen F4 HD204UI (SATA-II, 2 TB, 5,400 RPM, 32 MB, NCQ)

·         Chassis: Antec Twelve Hundred (front panel, three Noiseblocker NB-multiframe S-Series MF12-S2 fans at 1,020 RPM, back panel: two-BlackSilenPRO Noiseeblocker NB PL-1 fans at 1,020 RPM, top panel: standard 200 mm fan at 400 RPM)

·         Operating and control panel: Zalman ZM-MFC3

·         Source: Seasonic SS-1000XP Active PFC F3 1,000W (with a default 120 mm fan)

·         Display: 27 "Samsung S27A850D (DVI-I, 2560 × 1440, 60Hz)

Among all the graphics cards mentioned above, only Asus has higher nominal frequency at all, which is why we decided to adjust them with the original GeForce GTX 680 in order that our testing process is accurate:

The testing process

To reduce the dependence of the performance of the graphics card on its foundation speed, I overclocked the CPU with 6 cores of 32 nm with the 37x multiplier, BCLK frequency set at 125 MHz and "Load-Line Calibration" enabled at 4.625 GHz. The Vcore processor was increased to 1:49 V in the BIOS of the motherboard:

The Hyper-Threading Technology is allowed. The 16 GB DDR3 system memory operates with 2 GHz frequency parameters, which are 9-11-10-28 timings and the voltage is 1.65 V.

The trial began on February 24, 2013. All the tests were done based on the Microsoft Windows 7 Ultimate x64 SP1 operating system with all updates and driver parameters up to date as follows:

·         Intel Chipset Drivers WHQL from 07.02.2013 for the motherboard chipset;

·         DirectX End-User Runtimes libraries

·         AMD Catalyst 13.2 Beta 5 ( + driver from Catalyst Application Profiles 05/02/2013 12:11 (Fiber2) for the graphic card of AMD platforms

·         Nvidia GeForce 314.09 WHQL driver for GeForce GTX TITAN from 21.02.2013 and from 02.18.2013 GeForce 314.07 WHQL for GeForce GTX 690 and GTX 680

We conducted two tests with the following resolutions: 1920x1080 and 2560x1140. The test was conducted with two different image modes: "Quality + AF16x", the default image quality with the driver that allows the image filter cut-aliasing of 16, and "Quality+AF16x+MSAA 4 (8)x", that allows the image filter cut-aliasing process of 16x and full screen of 4x and 8x if the average frame rate is enough to experience the game in a relaxed manner. We also allow the filter and aliasing filter cutoff of the image while installing the game. If this requirement is not fully equivalent, we change them in Control Panels, the Catalyst drivers and GeForce. Here, we also disable Vsync. There was no other change in the driver installation item.
