NVIDIA GeForce Titan is taken from the name of a supercomputer named Titan at the Oak Ridge National Laboratory located in Tennessee, America which in November 2012 was named the fastest supercomputer in the world. Each GTX Titan is powered by the NVIDIA GK110 GPU, the same GPU found in the 18,668 Tesla K20X GPU Accelerator inside the Titan supercomputer. With 2,688 CUDA cores and 7.1 billion transistors, the GK110 is by far the fastest GPU ever made. To complement these powerful components, the GTX Titan is equipped with the latest NVIDIA technology, GPU Boost 2.0.
The first GPU Boost technology was released last year with the GTX 680 and is designed to dynamically adjust the core clock speed by utilizing the available power to increase performance. GPU Boost 2.0 on the GTX Titan works in a similar way, but takes advantage of GPU temperature limitations. This feature will work very well with the liquid cooling system. For those who complain about the GTX 680 memory, the GTX Titan comes with 50 percent more memory bandwidth than the GTX 680 with a 384-bit memory interface and that’s 6 GB of VRAM with a clock speed of 6008 MHz DDR (GDDR%). On our benchmarks, the GTX Titan beat NVIDIA’s previous flagship graphics card, the GTX 680, by about 50-75 percent.
The performance of this graphics card is only slightly behind the dual GPU GeForce GTX 690, only 10-15 percent behind in some benchmarks. In our overclock attempts, we were able to increase the core clock speed from 836 MHz to 1015 MHz and the memory from 6008 MHz to 6800 MHz DDR, which resulted in an average performance increase of 15 percent, bringing performance on par with the reference version of the GTX 690. The temperature and power consumption are 20 percent higher than the GTX 680, but this is allegedly due to the GPU Boost 2.0 technology. The performance of the GTX Titan is truly impressive for a single GPU graphics card, but it’s the price that is the biggest problem. Priced at around US$ 1000, it is the same value as the more powerful dual GPU graphics card, the GTX 690. In reality the GTX Titan doesn’t really have much of an advantage over the GTX 690: it’s not that different in size – a chassis that can fit a GTX Titan can also fit a GTX 690 – and operating temperature is also not much different. Power consumption is only 7 percent lower.
Unfortunately, the reason for the price of the GTX Titan is only due to the use of the GK 110 GPU, which costs a lot to produce – and in fact until now it has only been used on the Tesla K20 enterprise-class graphics card which costs US$ 3500; NVIDIA has not been able to reach the lower economy class. Although the performance of the GTX Titan is very impressive, we still recommend that you choose the GTX 690. Unless you want to buy prestige by owning a graphics card with a GK110 GPU, a GPU that can be found in the world’s fastest supercomputers.
