NVIDIA GeForce RTX 4090 Ti – Enthusiast desktop GPU

Description

The NVIDIA GeForce RTX 4090 Ti is an enthusiast-class desktop graphics card based on the Ada Lovelace AD102-400 GPU, configured with an extremely high shader count and designed for uncompromising 4K gaming and heavy content creation workloads. According to database specifications, it uses TSMC’s 5 nm process and integrates approximately 76.3 billion transistors on a 609 mm² die, making it one of the largest and most complex consumer-oriented GPUs ever listed. Although the card was never officially released to the retail market, its configuration positions it above the GeForce RTX 4090 within the GeForce RTX 40 series for theoretical performance and feature set [page:1].

The GeForce RTX 4090 Ti features 18,176 shading units (CUDA cores), 568 texture mapping units and 192 ROPs, along with 568 Tensor Cores and 142 dedicated RT Cores for AI and ray tracing acceleration. The GPU operates at a base clock of 2325 MHz and can boost up to 2565 MHz, depending on thermal and power headroom. This aggressive configuration delivers up to 93.24 TFLOPS of FP32 compute performance, with similar 93.24 TFLOPS in FP16 at a 1:1 ratio, as well as very high pixel and texture fill rates of 492.5 GPixel/s and 1,456.9 GTexel/s respectively [page:1].

For memory, the RTX 4090 Ti is paired with 24 GB of GDDR6X running at an effective 24 Gbps on a 384-bit memory interface, providing a massive 1.15 TB/s of memory bandwidth to sustain ultra-high-resolution gaming and demanding professional workloads. The GPU also includes a sizable 96 MB L2 cache and 128 KB of L1 cache per SM, which help reduce memory latency and improve effective bandwidth in complex scenes and compute workloads. This memory subsystem and large cache complement the high core counts to keep the GPU fed in 4K and beyond [page:1].

Board design information lists the GeForce RTX 4090 Ti as a triple-slot card measuring 336 mm in length, 140 mm in height and 61 mm in thickness, equipped with a robust cooling solution to handle its 600 W TDP. Power is supplied via two 16-pin power connectors, and NVIDIA recommends a 1000 W power supply to ensure stable operation under full load. The card connects to the system over a PCI Express 4.0 x16 interface, offering ample bandwidth for current gaming, content creation and compute use cases [page:1].

Display connectivity includes one HDMI 2.1 port and three DisplayPort 1.4a outputs, supporting high refresh rate 4K and 8K displays as well as multi-monitor setups for gaming, streaming and productivity. As an Ada Lovelace GPU, the RTX 4090 Ti supports DirectX 12 Ultimate, Vulkan 1.4, OpenGL 4.6 and CUDA 8.9, enabling advanced graphics features such as hardware-accelerated ray tracing, variable-rate shading and the latest DLSS implementations in supported titles [page:1].

Overall, the NVIDIA GeForce RTX 4090 Ti, as specified in enthusiast databases, represents a theoretical ultra-high-end variant of the AD102 GPU with higher clocks, more cores and increased power consumption compared to the RTX 4090, targeting users who demand maximum performance for extreme 4K gaming, high-refresh competitive titles and demanding creative or compute workloads, despite never becoming an officially released retail product [page:1].
