Meet T-Rex: Nvidia's Titan RTX is the new graphics card mega-monster

But gamers should stick with the GeForce RTX 2080 Ti instead.

When the GeForce RTX 2080 Ti launched with a sky-high $1,000 theoretical price tag and $1,200-plus actual price tag, some people speculated that it simply took the place of the Titan at the top of Nvidia’s graphics card lineup. Nope. On Monday, Nvidia revealed the Titan RTX, a $2,499 behemoth that the company also calls “T-Rex.”

It’s certainly monstrous enough. Like its Titan V predecessor, the Titan RTX returns to the Titan’s roots as a prosumer card, with a focus on AI, data science, and content creation tasks. Nvidia’s flagship TU102 GPU packs 72 dedicated RT cores for real-time ray tracing and 576 tensor cores so beloved by machine learning tasks. That’s identical to the GeForce RTX 2080 Ti’s loadout.

While Nvidia’s announcement didn’t specify the Titan RTX’s CUDA core count, an Nvidia spokesperson confirmed that it holds more than the GeForce card. The Titan RTX matches the 4,608 CUDA cores inside the Quadro RTX 6000 and RTX 8000 professional GPUs, rather than the RTX 2080 Ti’s 4,352 cores. That gives the newest Titan fewer total CUDA cores than its predecessor—the Titan V crammed in 5,120—but the Turing GPU’s CUDA cores are much more effective than the ones inside older Pascal GPUs. The extra cores also help the card perform deep-learning tasks more efficiently: The RTX 2080 Ti performs FP16 tasks at 110 teraflops, while Nvidia said the Titan RTX churns through the same tasks at 130 TFLOPS

Data tasks can require much more memory than gaming, so Nvidia loaded “T-Rex” with VRAM. The Titan RTX comes with 24GB of cutting-edge GDDR6 memory, for a total memory bandwidth of 672GB per second. That matches the Quadro RTX 6000’s configuration, and more than doubles up the GeForce RTX 2080 Ti, which has “only” 11GB of VRAM.

It’s an interesting decision by Nvidia. The Titan V included only 12GB of onboard memory, presumably to differentiate it from the pricier Quadro options. While the Titan RTX’s $2,499 price may stagger gamers, the Quadro RTX 6000 costs $6,300.

Such a powerful arsenal of cutting-edge hardware should make the Titan RTX stomp through machine-learning tasks. Nvidia’s supporting it on the software side with RAPIDS open-source software libraries that rely on CUDA. Nvidia also says that the tensor cores and ray-tracing hardware unlock new possibilities in creative applications, and the card’s fearsome firepower and massive memory pool gives it potent chops in traditional rendering tasks, too. The Titan RTX can even perform real-time 8K video editing, Nvidia says.

The new Titan sports the upgraded dual-axial cooler design introduced with the consumer GeForce RTX cards, but its aluminum shroud comes clad in gold, not silver.

Look for the Titan RTX to launch in the United States and Europe later in December for $2,499. Thanks to those extra CUDA cores, T-Rex should (slightly) outpunch the GeForce RTX 2080 Ti flagship in gaming, but at twice the price. so gamers who want to drive a 4K, 144Hz G-Sync HDR monitor like the sublime Acer Predator X27 should leave the Titan RTX for the data scientists and stick to the GeForce RTX 2080 Ti instead.
