AMD Radeon RX 7900 GRE vs NVIDIA TITAN RTX Comparison

The Verdict

The data presents a clear picture: the AMD Radeon RX 7900 GRE wins 8 of 10 head-to-head benchmarks against the NVIDIA TITAN RTX, with an average benchmark score of 32,456 versus 31,676. The AMD card sits at the 77th percentile of all GPUs, one point above the TITAN RTX’s 76th percentile. In raw performance terms, the RX 7900 GRE is the faster card in most workloads, particularly in DirectX 11, DirectX 9, and compute-heavy tasks. However, the TITAN RTX holds one significant advantage: it wins the Vulkan benchmark by 26.6%, which suggests NVIDIA’s architecture retains a lead in that specific API.

For a buyer choosing strictly from this data, the RX 7900 GRE is the pick for anyone prioritizing modern gaming performance, DirectX 12, or general compute throughput. The TITAN RTX, despite being end-of-life, remains relevant only for users who specifically need Vulkan performance or require 24 GB of memory (a capacity the AMD card cannot match). The RX 7900 GRE is also the more sensible choice for longevity: it is still in active production, whereas the TITAN RTX is discontinued. The AMD card’s launch MSRP is 549 USD, while the TITAN RTX launched at 2,499 USD — though pricing considerations are noted, the performance gap does not justify that difference for most workloads.

Architecture Differences

The two cards come from fundamentally different design generations. The AMD Radeon RX 7900 GRE uses the Navi 31 chip built on a 5 nm process at TSMC, packing 57,700 million transistors into a 529 mm² die. The NVIDIA TITAN RTX uses the TU102 chip on a 12 nm process, also at TSMC, with 18,600 million transistors on a larger 754 mm² die. The transistor density difference is stark: the AMD chip achieves 109.1M transistors per mm², versus 24.7M for NVIDIA. This explains why the RX 7900 GRE can deliver higher performance while consuming less power — its TDP is 260 W versus 280 W for the TITAN RTX.

The RX 7900 GRE is built on RDNA 3.0 architecture, codenamed Plum Bonito, from the Navi III generation. The TITAN RTX uses Turing architecture from the GeForce 20 generation. AMD’s card has 5,120 shading units, 320 TMUs, and 160 ROPs, while NVIDIA’s card has 4,608 shading units, 288 TMUs, and 96 ROPs. The AMD card also has 80 ray tracing cores, compared to 72 for NVIDIA. Notably, the TITAN RTX has 576 tensor cores, which the AMD card lacks entirely — a feature that could matter for AI workloads, though the benchmark data does not directly test tensor performance.

Memory configurations differ significantly. The RX 7900 GRE has 16 GB of GDDR6 on a 256-bit bus, delivering 576.0 GB/s bandwidth. The TITAN RTX has 24 GB of GDDR6 on a 384-bit bus, delivering 672.0 GB/s bandwidth. Despite the TITAN RTX’s higher raw bandwidth, the AMD card achieves higher effective throughput in practice, as benchmark scores show. The RX 7900 GRE also supports PCIe 4.0 x16, while the TITAN RTX is limited to PCIe 3.0 x16 — a generational interface advantage for AMD.

Where Each One Wins

The AMD Radeon RX 7900 GRE is the clear winner for DirectX-based workloads. It wins every DirectX test in the benchmark suite: DirectX 9 by 39%, DirectX 11 by 58.7%, and DirectX 12 by 21.6%. It also dominates compute tasks, with a 49.7% lead in GPU compute and a 21.3% lead in OpenCL. For modern gaming, the 3DMark Steel Nomad DX12 result shows AMD ahead by 26.9%, which suggests the RX 7900 GRE is better suited for current AAA titles. The AMD card also wins the Passmark G3D test by 32.2%, reinforcing its overall gaming superiority. Additionally, the RX 7900 GRE is the only card still in production, and its 5 nm process gives it a power efficiency advantage — 260 W TDP versus 280 W — while delivering higher performance.

The NVIDIA TITAN RTX wins in two specific areas. First, Vulkan performance: the Geekbench Vulkan score of 136,073 is 26.6% higher than AMD’s 99,850, indicating that Vulkan-based games or applications may favor the NVIDIA card. Second, the DirectX 10 test shows a modest 5.4% advantage, though this is a legacy API with limited modern relevance. The TITAN RTX also offers 24 GB of memory versus 16 GB, which could be decisive for memory-bound workloads like large datasets or high-resolution textures, though the benchmark data does not directly test this. For users who prioritize Vulkan titles or need maximum memory capacity, the TITAN RTX remains a viable option despite its age. For everyone else, the RX 7900 GRE is the data-backed choice.
