NVIDIA GeForce RTX 4080 Ti – High-end desktop GPU

Description

The NVIDIA GeForce RTX 4080 Ti is a high-end desktop graphics card based on the Ada Lovelace AD102-225-A1 GPU, positioned between the GeForce RTX 4090 and RTX 4080 series in theoretical performance. Built on TSMC’s 5 nm process with around 76.3 billion transistors and a 609 mm² die, it targets enthusiasts who demand strong 4K gaming performance and advanced ray tracing features in modern titles. Although the card was never released to retail, its configuration sits within NVIDIA’s GeForce RTX 40 generation and supports DirectX 12 Ultimate for next‑generation graphics features [page:1].

The AD102 GPU at the heart of the RTX 4080 Ti is configured with 14,080 shading units (CUDA cores), 440 texture mapping units and 144 render output units, alongside 440 Tensor Cores and 110 dedicated RT Cores for AI acceleration and hardware ray tracing. The GPU operates at a base frequency of 2340 MHz and can boost up to 2610 MHz depending on thermal and power headroom. This setup delivers up to 73.5 TFLOPS of FP32 compute performance, 73.5 TFLOPS of FP16 at a 1:1 ratio, and high pixel and texture fill rates of 375.8 GPixel/s and 1,148.4 GTexel/s respectively, making it well suited for high‑refresh 1440p and 4K workloads [page:1].

Memory is handled by 16 GB of GDDR6X connected via a 256‑bit interface, running at an effective 21.2 Gbps data rate for a total bandwidth of 678.4 GB/s. The GPU also incorporates 80 MB of L2 cache and 128 KB of L1 cache per SM to reduce latency and improve effective bandwidth in complex scenes and compute workloads. This combination of sizable VRAM capacity, fast GDDR6X and large on‑chip cache helps sustain performance in high‑resolution gaming, content creation and GPU‑accelerated applications [page:1].

Board design details list the GeForce RTX 4080 Ti as a triple‑slot card measuring 336 mm in length, 140 mm in height and 61 mm in thickness, using a substantial cooling solution to manage its 400 W TDP. Power is supplied through a single 16‑pin connector, with a recommended power supply rating of 800 W to ensure stability under full load. The card interfaces with the system via PCI Express 4.0 x16, providing ample bandwidth for current games and productivity workloads [page:1].

Display connectivity consists of one HDMI 2.1 port and three DisplayPort 1.4a outputs, enabling multi‑monitor setups and support for high‑refresh 4K and 8K displays. As part of the Ada Lovelace family, the RTX 4080 Ti supports DirectX 12 Ultimate, OpenGL 4.6, Vulkan 1.4 and CUDA 8.9, allowing it to leverage hardware‑accelerated ray tracing, variable‑rate shading and DLSS in supported titles while providing strong compute capabilities for CUDA‑based applications [page:1].

Overall, the NVIDIA GeForce RTX 4080 Ti as specified in enthusiast databases represents a powerful high‑end Ada GPU configuration with more cores and bandwidth than the standard RTX 4080, targeting users who need excellent 4K gaming performance, advanced ray tracing and strong compute throughput in a 400 W triple‑slot form factor, despite never becoming an officially released consumer product [page:1].
