Nvidia has finally officially revealed the RTX 2070, 2080 and 2080 ti and two of these cards are already available for pre-order. The reveal was made in a livestream in Cologne, Germany which took place before the start of Gamescon 2018.
The company usually waits months before launching the ti version of the flagship but this time the 2080 and 2080 ti are launching together.
The three RTX cards that support real time ray tracing, a technology that allows photorealistic lighting to be rendered in real time. The technology is abbreviated to RTX and this is where the new branding comes from. Microsoft developed the DirectX Ray tracing API, Epic is set to add RTX support to Unreal Engine 4 and other companies are expected to announce support for ray tracing soon.
The quantity of RAM remains the same as the previous generation, 8GB for the 2070 and 2080 and 11 for the 2080 ti, the difference is that the memory type is now DDR6 instead of DDR5X and the memory speed has increased to 14 gbps in all 3 cards from 8, 10 and 11 gbps respectively.
Memory bandwidth has been increased from 352 GB/s to 448 in the 2080 with the 2070 having the same bandwidth as the 2080 and the 2080 ti having a bandwidth of 616GB/s. CUDA core count has increased from 2560 to 2944 in the 2080 and from 3584 to 4352 in the 2080 ti, while the 2070 has 2304. TDP remains the same for the RTX 2080 ti at 250 watts, the 2080 has a TDP od 215, which is an increase over the 1080’s 180 watt TDP and the 2070 has a TDP of 175W.
The cards will also come with a USB Type C VirtualLink port as well as the usual DisplayPort 1.4 and HDMI2.0 ports, this will be used to allow VR headsets to connect with a single cable rather than using HDMI and USB as is currently required. The cards will be capable of a maximum output of 8K at 60hz, that is 7680 x 4320, however this does require the use of 2 Displayport 1.4 cables.
The new Turing cards are a power hungry bunch, with the 2080 and 2080 ti requiring at least a 650 watt power supply. The 2080 needs an eight and a six pin power input, the 2080 ti needs two eight pin inputs and the 2070 only needs one eight pin and a 550 watt PSU making it the least demanding.
Unsurprisingly, the price tags have got a bit heftier with the Founders edition of the cards retailing at 599 US Dollars for the 2070, 799 dollars for the 2080 and 1199 for the 2080 ti. Of course the prices are higher for those of us in the UK, here the cards will cost 569, 749 and 1099 pounds respectively, with the 2080 ti costing the equivalent of over 1400 US dollars. The non-founders edition cards will vary in price with prices starting at 499 US dollars. Pre-orders of the 2080 and 2080 ti are available on Nvidia’s website and the actual release date is the 20th of September, not many details were given for when the 2070 will be available other than that it will be some time around October.
