There is more compute power with the NVIDIA Titan RTX. Perhaps the headline spec is the 24GB of memory. With larger on-card memory, the Titan RTX is able to handle more data with larger models. We have a case where this was necessary in our review.
Testing the NVIDIA Titan RTX
Testing the NVIDIA Titan RTX we are using our standard GPU test platform. At STH, we use the dual Intel Xeon server because it gives the option for a higher-memory configuration as well as higher-end storage and networking configurations. If you have a Titan RTX or two, you are likely to also expand in these areas.
• Motherboard: ASUS WS C621E SAGE Motherboard
• CPU: 2x Intel Xeon Gold 6134 (8 core / 16 Threads)
• GPU: NVIDIA Titan RTX
• Cooling: Noctua NH-U14S DX-3647 LGA3647
• RAM: 12x MICRON 16GB Low Profile
• SSD: Samsung PM961 1TB
• OS: Windows 10 Pro and Ubuntu 18.04
GPU-Z shows the primary stats of our testing the Titan RTX. The TU102 Turing GPU clocks in at 1330 MHz. And GDDR6 Memory at 1748 MHz. Pixel Fillrates run at 168 GPixels/s, and Texture Fillrate comes in at 672 GTexel/s.
Software Used: ASUS GPU Tweak
GPU Tweak II software from ASUS used to set different configs and monitor GPU data for its graphics cards. Although the graphics are relatively large when displayed onscreen, it can be minimized to the taskbar when not needed.
ASUS GPU Tweak is a very convenient way to switch modes on the NVIDIA Titan RTX, we use this on our main workstation and test bench. Three main presets set operating modes with a click of the button, Silent Mode (1750 MHz GPU Speed), Game Mode (1770 MHz GPU Speed), and OC Mode (1790 MHz GPU Speed), we run our benchmarks on all three settings. When sitting on the desktop doing MS Office work Silent mode works great, saves power and lowers heat output. When ready for workloads click the OC button to improve performance.
Let us move on and start our testing with computing-related benchmarks.
