First of all, let’s examine the difference between the Gigabyte GeForce GTX Titan Black GHz Edition 6GB (at 1006-1111/7000 MHz) and the Zotac GeForce GTX Titan Black 6GB (at 889-980/7000 MHz).
The Gigabyte is an average 6-7% faster than the Zotac across all of our tests, the biggest gap of 10% being observed in GRID 2 at the resolution of 2560x1440 pixels.
It’s also interesting to compare the Gigabyte GeForce GTX Titan Black GHz Edition and the ASUS ROG Matrix GTX 780 Ti Platinum. The difference between them boils down to the amount of onboard memory and the higher boost clock rate of the Gigabyte model. That’s why they deliver the same performance in practice.
It is only in the high-quality test mode of Total War: Rome II at 2560x1440 that the Gigabyte’s advantage is as high as 10-12%. Otherwise, the two cards are equals.
And finally, we will compare the Gigabyte GeForce GTX Titan Black GHz Edition with the dual-processor Nvidia GeForce GTX 690.
Despite the increased clock rates and three times more graphics memory per GPU, the Gigabyte GeForce GTX Titan Black GHz Edition cannot win this fight. It is only ahead in Metro: Last Light, in the high-quality test modes of Company of Heroes 2 and Total War: Tome II and also in Batman: Arkham Origins (with antialiasing turned on). In the rest of the games the Nvidia GeForce GTX 690 is at least as fast as its opponent and definitely faster in the relatively older games. So, people who bought their GTX 690 a couple of years ago can still rest assured that they own one of the best graphics cards available.
Performance in CUDA and OpenCL Applications
Besides traditional tests in 3D benchmarks and games, we will run a few computing and encoding programs that use CUDA (Compute Unified Device Architecture) and OpenCL algorithms. Only Nvidia-based products will be tested here. The Zotac GeForce GTX Titan Black is replaced with a reference GeForce GTX Titan in this section of our review.
First goes the SmoothVideo Project (SVP) benchmark SVPMark 3.0.3a. Here’s how many points the graphics cards scored in the GPU test.
The graphics cards are close to each other, yet the dual-processor GeForce GTX 690 is the formal winner.
Next goes DirectCompute Benchmark version 0.45b. We show you both DirectCompute and OpenCL results.
The Gigabyte GeForce GTX Titan Black GHz Edition wins the DirectCompute test but the dual-processor GeForce GTX 690 is superior in the OpenCL mode.
The last synthetic OpenCL test on our list is the GPGPU benchmark from the AIDA64 utility version 4.50.3006 beta. We show you the Single-Precision FLOPS and Double-Precision FLOPS results.
The Gigabyte GeForce GTX Titan Black GHz Edition is considerably faster than the reference Titan but the results of the ASUS ROG Matrix GTX 780 Ti suggest that the advantage is due to higher clock rates rather than to superior computing capabilities.
LuxMark is a more practical benchmark because it shows what performance we can expect from the graphics cards with the LuxRender engine.
The Gigabyte GeForce GTX Titan Black GHz Edition wins this test, being 24.7% ahead of the reference GTX Titan. On the other hand, the ASUS ROG Matrix GTX 780 Ti is almost as fast as the Gigabyte.
Arion Bench version 2.5.0 is based on the Arion 2 technology and supports hardware acceleration on Nvidia GPUs. We use two rendering methods: hardware (on the GPU) and hybrid (GPU + CPU).
We’ve got the same standings here as in LuxMark above.
And finally, we benchmarked the speed of HD video encoding with Xilisoft Video Converter Ultimate version 7.8.1. We encoded a Full-HD 1.77GB video file (Disney’s Puss in Boots: The Three Diablos) for the iPad 4. The resulting file was about 441 MB large. The less time it took the card to transcode the video, the better.
The 6-core Intel Core i7-3970X Extreme Edition processor clocked at 4.8 GHz shows the usefulness of CUDA because it is 25% slower than the fastest graphics card. And the utility can use up all of the CPU's resources (its load level was 77% during the test). The graphics cards are comparable to each other, the Gigabyte being just a formal winner.
