Everything You Need To Know About The NVIDIA GeForce RTX Graphics Cards
It’s an exciting time for gamers as Nvidia has just unveiled its next generation of graphics cards after months of rumors and leaks. It’s official: the next generation of Nvidia GPUs will be situated in the GTX/RTX 20xx series and the company brings a major new change to the table: Raytracing.
The graphics chip manufacturer has officially unveiled the GeForce RTX 2070, RTX 2080 and the RTX 2080 Ti at the Gamescom conference in Cologne. All of these are based on the Turing architecture and offer substantial performance upgrades compared to the last generation, but with added features such as real-time raytracing.
All of the RTX-branded GPUs will come with support for Nvidia’s real-time raytracing. The 2060 models and lower – which will be introduced at a later time – will remain to have the GTX branding. In short, raytracing allows for the rendering of much more realistic images, shadows, and lighting, in particular. This usually requires an incredible amount of horsepower to render in real-time, but Nvidia has been able to come up with a sort of hybrid solution (using traditional rasterization) in order to achieve raytracing via new RT-cores on the chip. Regular GPU horsepower is usually expressed in Teraflops, but Nvidia has introduced the term ‘Gigarays’ in order to indicate raytracing performance of a certain chip. The flagship model, the RTX 2080 Ti, is able to achieve 10 Gigarays per second.
Microsoft has previously released the DXR API and plenty of games have confirmed support for Nvidia’s raytracing method, including the upcoming Battlefield V, Control, Metro Exodus and Shadow of the Tomb Raider. More games are reportedly on their way, including the popular battle royale title Player Unknown’s Battlegrounds. You can read more about raytracing in our article over here. Raytracing does seem to have a serious performance hit, however, as the latest build for Rise of The Tomb Raider isn’t able to hit a stable 60 FPS at 1080p with raytracing enabled on a GTX 2080 Ti.
Another new feature uses AI and machine learning for better and more efficient post-processing, called DLSS (deep learning supersampling).
In terms of raw, non-ray-tracing performance, Nvidia has promised that all of the newly announced cards perform over 50% better than their previous-generation counterparts. The switch to GDDR6 allows for a much higher memory bandwidth compared to GDDR5X and the amount of CUDA cores has also been significantly increased.
Another change is the replacement of SLI with NVLink. The latter is the new connection between two graphics cards, although only the 2080 and 2080 Ti offer support – combining two 2070 cards for better performance isn’t possible anymore.
The GeForce RTX 2070 features 2304 CUDA cores running at 1410 MHz, 8 GB of GDDR6 Memory, a 256-bit bus and a raytracing performance of 6 Gigarays/s. The 270 carries a price tag of $499. Maximum power consumption is rated at 175 watts.
Next up is the RTX 2080, which offers the same amount of memory. There are more CUDA cores, however, 2944 to be specific running at 1515 MHz. Whereas the RTX 2070 only requires a single 8-pin power connector, the RTX 2080 will need an additional 6-pin power connector as well. The GeForce 2080 will consume up to 225 watts of power. The GPU achieves a raytracing performance of 8 Gigarays/s. Nvidia is pushing the RTX 2080 as the perfect graphics card for 4K, HDR and 60 FPS gaming on high/ultra settings. The recommended retail price is $699.
The ultimate flagship model is the Nvidia GeForce GTX 2080 Ti, with no less than a whopping 4352 CUDA cores running at 1350 MHz. A 352-bit memory bus controls 11 gigabytes of GDDR6 chips. Raytracing performance is stated at 10 Gigarays/s. The price tag for a 2080 Ti is set at $999.
Nvidia will also release Founder’s Editions of the GPUs, which have a surplus of $100 for the 2070 and 2080, and an added $200 for the Ti. The Founder’s Edition cards feature Nvidia’s own reference design as well as higher boost clock speeds – something that third-party vendors will offer as well. All of the cards will release on September 20th, and pre-orders can already be registered.
