Nvidia GeForce RTX 4080 16GB Specs
The Nvidia GeForce RTX 4080 16GB is based on the Ada Lovelace 4nm architecture. It has 9728 CUDA cores running at a base clock of 2.21 GHz and a boost clock of 2.52 GHz. There are 45.9 billion transistors on board with 304 texture units and 112 ROPs.
The Nvidia GeForce RTX 4080 16GB is a Desktop GPU from the GeForce 40 series with a die size of 378.6 mm². The codename is AD103-300 and the fabrication process uses TSMC 4nm. For cores there are 76 ray tracing cores in addition to 304 tensor cores. There is 64 MB of L2 cache.
On the memory side of the Nvidia GeForce RTX 4080 16GB, there is 16GB of GDDR6X video memory running at an effective memory clock of 22400 MHz. It is powered by a memory interface width of 256-bit and a memory bandwidth of 716.8 GB/s.
The theoretical performance is based on the clock speed, cores and the floating point operations per clock cycle. The half precision FP16 performance comes in at 48.83 TFLOPS, the single precision comes in at 48.83 TFLOPS and the double precision FP64 performance is 0.763 TFLOPS. The FP16 half precision floating point operations per clock cycle is 2, for single precision FP32 it is 2 and for double precision FP64 it is 1/32. The texture fillrate is 763.04 GT/s and the pixel fillrate is 281.12 GP/s.
On the Nvidia GeForce RTX 4080 16GB there are many technologies including DirectX version 12, G-Sync, OpenCL 3.0, OpenGL 4.6, Shader Model 6.7 and it is VR Ready. Additionally, there are other technologies including Ray Tracing Cores 3rd Generation, Tensor Cores 4th Generation, NVIDIA DLSS 3, NVIDIA Reflex, NVIDIA Broadcast, Resizable BAR, NVIDIA GeForce Experience, NVIDIA Ansel, NVIDIA FreeStyle, NVIDIA ShadowPlay, NVIDIA Highlights, Game Ready Drivers, NVIDIA Studio Drivers, NVIDIA Omniverse, NVIDIA GPU Boost, NVIDIA Encoder (NVENC) 2x 8th Generation, NVIDIA Decoder (NVDEC) 5th Generation, AV1 Encode, AV1 Decode, CUDA Capability 8.9. There is no SLI on the Nvidia GeForce RTX 4080 16GB.
There are 3 Display Port 1.4a ports on this graphics card with a maximum digital resolution of 7680 x 4320 @ 60Hz. There is also a HDMI 2.1 for plugging into monitors and TVs. There is no USB-c, DVI or VGA on the Nvidia GeForce RTX 4080. The maximum HDMI resolution is 7680 x 4320 @ 60Hz and the maximum display port resolution is 7680 x 4320 @ 120Hz.
For maximum potential a PCI-e 4.0 x16 slot should be used (other lower version slots will still work). The Nvidia GeForce RTX 4080 requires 3 x 8 pin OR a 450W or greater PCIe Gen 5 cable. These connectors are required as the graphics card uses 320 W of power and Nvidia recommends a power supply unit of at least 700 W.
The Nvidia GeForce RTX 4080 comes in at 30.4 cm (11.97″) by 13.7 cm (5.39″) and is a 3 slot card at around 6.1cm (2.40″). This card cost $1199 USD at release on the 16th November 2022.
