The NVIDIA GeForce RTX 2080 and RTX 2080 Ti Review
New Generation, New Founders Edition
At this point, it seems that calling NVIDIA's 20-series GPUs highly anticipated would be a bit of an understatement. Between months and months of speculation about what these new GPUs would be called, what architecture they would be based off, and what features they would bring, the NVIDIA GeForce RTX 2080 and RTX 2080 Ti were officially unveiled in August, alongside the Turing architecture.
We've already posted our deep dive into the Turing architecture and the TU 102 and TU 104 GPUs powering these new graphics cards, but here's a short take away. Turing provides efficiency improvements in both memory and shader performance, as well as adds additional specialized hardware to accelerate both deep learning (Tensor cores), and enable real-time ray tracing (RT cores).

As unusual as it is for them NVIDIA has decided to release both the RTX 2080 and RTX 2080 Ti at the same time, as the first products in the Turing family.
The TU102-based RTX 2080 Ti features 4352 CUDA cores, while the TU104-based RTX 2080 features 2944, less than the GTX 1080 Ti. Also, these new RTX GPUs have moved to GDDR6 from the GDDR5X we found on the GTX 10-series.
One of the most significant departures with the RTX 2080 and RTX 2080 Ti can be found in the newly redesigned NVIDIA Founders Edition products.
Finally moving away from the blower-style cooler, the Founders Edition cards now feature a dual axial fan design, along with a vapor chamber that's the entire length of the card, as well as a substantially redesigned look.
Utilizing this new found cooling capacity, the Founders Editions cards will also be shipped in a factory overclocked state for the first time, 90MHz for both SKUs.
Since NVIDIA is generally the only person that ships their graphics cards at reference clock speeds, it's difficult to predict if we'll see any RTX cards clocked lower than the Founders Editions, but NVIDIA is claiming that these cards are in fact "overclocked."
Another addition to the Founders Edition cards and all of the third party RTX cards we've seen so far is the addition of a USB-C connector. This USB-C connector is VirtualLink compliant, a standard developed through coordination with NVIDIA, Oculus, Valve, Microsoft, and AMD to provide a one-cable solution for next-generation VR headsets.
The VirtualLink port is capable of providing 4 Lanes of HBR3 DisplayPort, USB 3.1 Gen 2 connectivity, as well as 27W of power delivery.
The RTX 2080 features an 8-pin and a 6-pin power connector, while the RTX 2080 Ti moves to two 8-pin connectors.
The other funky new connector on the RTX cards is NVLink. This communication protocol, previously seen in NVIDIA's Tesla and Quadro products provides a high-bandwidth replacement for SLI and will enable resolutions up to 8K (Single Link on the RTX 2080), and 8K Surround (Dual Link on the RTX 2080 Ti). However, NVLink is only compatible with 2 GPUs, officially ending the days of 3 and 4-way SLI, even if Pascal only featured support in select benchmarks.
Unlike the launch of the Pascal-based GTX 10-series cards, graphics card designs from third-party manufacturers such as MSI, EVGA, and ASUS will be ready and shipping on the same launch date as the Founders Edition (September 20th).
Here's just a small taste of what's in store for the coming weeks as we take a look at these new third-party designs.
