More details of the NVIDIA Turing TU102 GPU that powers the flagship GeForce RTX 2080 Ti flagship graphics cards have leaked out.
More details of the NVIDIA Turing TU102 GPU that powers the flagship GeForce RTX 2080 Ti and Quadro RTX 8000/6000 series graphics cards have leaked out over at Videocardz. In an exclusive article, the website discusses information that comes straight from the NVIDIA editor’s day, an event which is heavily NDA’d and discusses the architectural and performance aspects of the new GeForce graphics cards coming to the market.
The first details that are talked about are the Turing TU102 GPU block diagram. We have already seen t he bare chip and it’s massive in terms of die size, the biggest ever **102 GPU that NVIDIA’s ever produced. Measuring at 754mm2, the chip comes packed with 18.6 Billion transistors and a totally new architecture design featuring different cores that are operating in tandem to deliver the world’s best graphics chips for gamers to date.

The Turing TU102 GPU has 72 Streaming Multiprocessors (SM) featuring 64 CUDA cores each. The full die features 4608 CUDA cores while the GeForce RTX 2080 Ti features 4352 cores. The chip has 576 Tensor cores, 72 RT cores, 36 Geometry Units, 288 Texture Units (TMUs) and 96 ROPs (Raster Operation Units). In addition to the core specs, the chip has 384-bit memory interface supporting a 7 GHz GDDR6 (14 GHz Effective) DRAM design and 2 NVLINK channels. The chip features 6 MB of L2 cache too.

Now since we showed that the GeForce RTX 2080 Ti is based on a cut down TU102 core, the specs are slightly different. We get 68 SMs with 4352 Cores, 544 Tensor cores, 68 RT cores, 34 Geometry Units, 272 TMUs and 88 ROPs. The actual clock speeds are maintained at 1350 MHz base and 1545 MHz boost (1635 MHz OC). The chip features 11 GB of GDDR6 (next-gen) memory featured across a 352-bit bus and clocked at 14 GB/s. This leads to a total bandwidth of 616 GB/s.
In terms of shading performance which is the direct result of the enhanced core design and GPU architecture revamp, the Turing GPU offers an average uplift of 50% better performance per core compared to Pascal GPUs. In VR games, the shading performance would be a good 2x ahead than what Pascal achieved while many modern gaming titles show a ~50% lead over Pascal with Turing’s enhanced core design.
It should be pointed that these are just per core performance gains at the same clock speeds without adding the benefits of other technologies that Turing comes with. That would further increase the performance in a wide variety of gaming applications as we have already seen the gaming performance of a GeForce RTX 2080 to be 50% faster than the GTX 1080 on average and twice as fast with the new DLSS technology.
Lastly, there’s a new overclocking feature being talked about which the new Turing GeForce RTX graphics cards will be able to make use of. To be known as the Scanner (Final Name is still a work-in-progress), the feature will let the OC Utility detect the best clock speeds and voltages for you without the need to do anything. Just run a test through the overclocking utility and you are all set.
The feature is said to be implemented in many Overclocking utilities which will be updated by AIBs such as EVGA, MSI, ASUS, etc but would also be shipping inside new GeForce Experience software which sounds really interesting. This means we may be looking at an updated GeForce experience and software stack with the new cards launch.
One more thing to add, it is stated that the performance reviews of the GeForce RTX 2080 Ti and RTX 2080 have an embargo until 14th September so that is when we will be looking at the final reviewers. Also, NVIDIA hasn’t shipped the press with working drivers so for the time being, we will only have these official performance figures with us. That gives a 6-day margin for users to get the GeForce RTX products based on their impressions of the reviews.
The NVIDIA GeForce RTX 20 series launches today in reference variants first. This time, NVIDIA has already given the green light to their manufacturers to announce custom cards soon after the reference launch which are now available to pre-order on the official GeForce webpage. Or you can head over to this article and check out all the glorious non-reference models which you will be able to get very soon.
