NVIDIA GeForce RTX 20 Series - GeForce RTX 2080, The High-End
The NVIDIA GeForce RTX 2080 is the next chapter in high-performance gaming graphics cards. Featuring the latest Turing GPU architecture designed by NVIDIA, the GeForce RTX 2080 will allow gamers to play new VR experiences, games with real-time raytracing and 4K HDR content at improved FPS compared to the GeForce GTX 1080 with an expected performance jump of around 50%.
Coming to Turing, the GeForce RTX 2080 is powered by the Turing TU104 GPU. The TU104 GPU is the successor to NVIDIA’s GP104 GPU and sticks to the same principles which made the GTX 1080 and GTX 1070 great which is to offer gamers the best performance at the highest efficiency rate (perf/watt) and deliver products that are highly competitive in pricing and performance.
GeForce RTX — New Family of Gaming GPUs
The new GeForce RTX 2080 Ti, 2080 and 2070 GPUs are packed with features never before seen in a gaming GPU, including:
- New RT Cores to enable real-time ray tracing of objects and environments with physically accurate shadows, reflections, refractions, and global illumination.
- Turing Tensor Cores to perform lightning-fast deep neural network processing.
- New NGX neural graphics framework integrates AI into the overall graphics pipeline, enabling AI algorithms to perform amazing image enhancement and generation.
- New Turing shader architecture with Variable Rate Shading allows shaders to focus processing power on areas of rich detail, boosting overall performance.
- New memory system featuring ultra-fast GDDR6 with over 600GB/s of memory bandwidth for high-speed, high-resolution gaming.
- NVIDIA NVLink, a high-speed interconnect that provides higher bandwidth (up to 100 GB/s) and improved scalability for multi-GPU configurations (SLI).
- Hardware support for USB Type-C and VirtualLink, a new open industry standard being developed to meet the power, display and bandwidth demands of next-generation VR headsets through a single USB-C connector.
- New and enhanced technologies to improve the performance of VR applications, including Variable Rate Shading, Multi-View Rendering, and VRWorks Audio.

NVIDIA GeForce RTX 2080 ($799 USD) – The High-End GeForce Turing Graphics Card – 225W TDP and 8 GB GDDR6 Memory
The NVIDIA GeForce RTX 2080 features the TU104 GPU (TU104-400-A1) core which comprises of 2944 CUDA cores. NVIDIA’s 12nm FinFET architecture allows higher core count while retaining faster clock speeds which we have already seen on Pascal cards. The chip houses 13.6 Billion transistors which are a nice jump compared to the 7.2 Billion transistors on the Pascal GP104 GPU. The card delivers much higher performance due to enhanced core design that adds incremental IPC gains.
The actual clock speeds are maintained at 1515 MHz base and 1710 MHz boost (1800 MHz OC on Founders Edition). The chip features 8 GB of GDDR6 (next-gen) memory featured across a 256-bit bus and clocked at 14 GB/s. This leads to a total bandwidth of 448 GB/s.
The NVIDIA GeForce RTX 2080 features just 225W TDP on Founders Edition and 215W TDP on non-Founders Edition cards. Coupled with a very smooth power delivery system to avoid leakage, the chip is one of the most efficient GPU architecture ever designed for gamers. The display outputs for the card include 3 Display Port 1.4 (4K @ 120 Hz), 1 HDMI 2.0b (4K @ 60 Hz) and USB Type-C connector for the Virtual link which means that it is capable to support all next-gen displays with new standards. Power is fed through an 8 and 6 pin connector configuration.
NVIDIA GeForce RTX 20 Series Design, Next-Gen NVTTM With Dual Fan Cooler, Beefy Aluminum Fin Based Heatsink, Heavy Overclock Ready 8 Phase PCB, NVLINK For Multi-GPU Functionality
When it comes to the cooler design, NVIDIA is taking a major departure from their blower styled cooler from previous reference designs and going for a strong dual fan cooling system which is said to deliver better cooling performance. The cooler comprises of dual rotatory fans that push cool air towards a large heatsink block that is made up of several aluminum fins and interconnects via heat pipe technology. The cooler has a high-performance vapor chamber underneath the hood which uses a copper base to effectively dissipate heat from the GPU and surroundings such as the VRAM.
All of this is packed beneath an elegant looking cooler which doesn’t use the same design pattern as the GeForce 10 series founders edition cards. Those went with a more polygonal texture but this is more of a plain design featuring an aluminum shroud with a matte black finish in the center. The RTX 2080 / 2080 Ti logo is seen on the side and has LEDs to glow when the card is operational. The shroud engulfs the entire card, leading from the top and even the back which acts as a backplate and looks very neat.

In addition to the cooler, the RTX 20 series cards rock a single NVLINK connector, capable of offering dual way multi-GPU functionality. The RTX 2080 cards will operate at (x8/x8) mode while RTX 2080 Ti cards would operate in (x16/x16) mode.
