After two years running with GTX 10 series, NVIDIA finally launched the Turing-based GeForce RTX 2070, RTX 2080 and RTX 2080 Ti last month. At the heart of NVIDIA’s new series is the RTX Technology, which brings real-time ray tracing in games. Though not everything on your screen will be ray traced, but some of the objects are; and so, a hybrid of ray tracing and classic rasterization makes up the RTX Technology. Still, to ray trace just those few things on your screen, an enormous amount of computing power is needed, and so NVIDIA created specialized hardware for the task in the form of RT cores, which sit beside the all-purpose CUDA cores. The Tensor cores, which made their debut with “Volta,” also feature here, lending a hand with deep learning and AI tasks, including a few turnkey features game developers can integrate. The new architecture also keeps up with generational gains in memory bandwidth with the new GDDR6 memory standard. The display I/O is revamped with support for the latest DisplayPort and HDMI standards, and a revolutionary new connector called VirtualLink.

Today we are going to take look at two ASUS custom RTX cards, ROG STRIX RTX 2080 and RTX 2080 Ti. The ASUS ROG STRIX cards are the company’s most premium offing with fully custom PCB design with over-designed VRM and a triple fan cooler design. We decided to review both ROG STRIX RTX 2080 and RTX 2080 Ti together because physically there is no difference between them only difference is the different GPU core and the number of memory chips.
The ROG STRIX RTX 2080 Ti new consumer flagship graphics card featuring TU102 GPU, which has 4352 active shader processors, 11GB GDDR6 graphics memory on a 352-bit wide memory bus. The GPU has six Graphics Processing Clusters (GPCs), 36 Texture Processing Clusters (TPCs), and 72 Streaming Multiprocessors (SMs). Each SM contains 64 CUDA Cores, eight Tensor Cores, four texture units, and 96 KB of L1/shared memory. For Ray tracing acceleration, the TU102 has 68 RT cores with 544 tensor cores and 88 ROP units. The ROG STRIX RTX 2080 Ti comes with a factory overclock of boost clock 1650 MHz. The ROG STRIX RTX 2080 comes with TU104 GPU with 2944 shaders, 8GB GDDR6 graphics memory on a 256-bit wide memory bus and has 46 RT cores with 368 tensor cores. The ROG STRIX RTX 2080 also comes with a factory overclock of boost clock 1860.
