AMD Radeon RX 7900 GRE vs NVIDIA TITAN V Comparison

The benchmark data presents a clear generational clash between two very different GPU designs. The NVIDIA TITAN V, a Volta-based compute powerhouse from 2017, and the AMD Radeon RX 7900 GRE, a modern RDNA 3.0 gaming card, are separated by nearly six years of architecture. Across ten head-to-head tests, the AMD card wins eight, while the NVIDIA card takes two, but the margins and the nature of those wins tell a nuanced story about where each card excels.

Head-to-Head Benchmarks

The most decisive victory for the AMD Radeon RX 7900 GRE comes in the DirectX 11 PassMark test, where it scores 300 against the TITAN V's 152, a massive 49.3% advantage. This is not an isolated result; the AMD card also demonstrates strong leadership in compute-oriented workloads. In PassMark GPU Compute, the RX 7900 GRE scores 15,016 versus 9,263, a 38.3% lead. The 3DMark Steel Nomad DX12 test shows a similar trend, with the AMD card posting 4,814 points compared to the NVIDIA card's 3,565, a 25.9% difference. The pattern holds in older DirectX API tests, with the RX 7900 GRE leading by 31.3% in DirectX 9 (310 vs 213) and by 24.3% in DirectX 12 (107 vs 81).

The AMD card's lead extends beyond raw 3D rendering. In Geekbench OpenCL, it scores 175,758 versus 157,265, a 10.5% advantage. The 2D performance gap is also notable, with the RX 7900 GRE scoring 1,180 in PassMark G2D compared to 937 for the TITAN V, a 20.6% difference. The most significant overall 3D performance gap is seen in PassMark G3D, where the AMD card scores 27,089 against the TITAN V's 19,805, a 26.9% lead.

However, the NVIDIA TITAN V is not without its own victories. The most striking is in Geekbench Vulkan, where it scores 152,117 against the RX 7900 GRE's 99,850. This 52.3% advantage is the single largest margin in any test. The TITAN V also wins the PassMark DirectX 10 test, scoring 153 versus 139, a 10.1% lead. These two wins for the NVIDIA card highlight its strength in specific API environments, particularly Vulkan, where its architecture appears to be exceptionally well-optimized.

Looking at the overall averages, the picture is more complex. The TITAN V has a higher average benchmark score of 34,355 compared to the RX 7900 GRE's 32,456. This is reflected in their percentile rankings, where the TITAN V sits in the 79th percentile of all GPUs, while the RX 7900 GRE is in the 77th. This suggests that while the AMD card wins more individual tests, the NVIDIA card's performance is more consistent across the entire benchmark suite. The TITAN V's nearest rivals in average score are the NVIDIA RTX A1000 (34,207, a 0.4% difference) and the AMD Radeon HD 7970 (34,541, a -0.5% difference). The RX 7900 GRE's nearest rivals are the AMD FirePro S10000 (32,388, a 0.2% difference) and the AMD FirePro S9300 X2 (32,540, a -0.3% difference).

The Verdict

The data supports a clear split in use cases. For gamers and users prioritizing modern DirectX and compute-heavy workloads, the AMD Radeon RX 7900 GRE is the superior choice. Its wins in DirectX 11, DirectX 12, and GPU Compute are decisive, with margins ranging from 24.3% to 49.3%. The 3DMark Steel Nomad DX12 result, a modern benchmark, shows a 25.9% lead for the AMD card, indicating better performance in contemporary gaming scenarios. The RX 7900 GRE's 16 GB of memory also provides a capacity advantage over the TITAN V's 12 GB.

For users working with Vulkan-based applications, the NVIDIA TITAN V is the clear winner. The 52.3% lead in Geekbench Vulkan is substantial and suggests that the Volta architecture has a significant optimization advantage in this API. The TITAN V also holds a slight edge in DirectX 10, but the more compelling reason to choose it is its higher overall average benchmark score (34,355 vs 32,456) and its 79th percentile ranking, indicating strong all-around performance. The TITAN V is an end-of-life product, while the RX 7900 GRE is actively in production, which is a practical consideration for long-term support.

Architecture Differences

The two GPUs represent fundamentally different design philosophies. The NVIDIA TITAN V is built on the Volta architecture using a 12 nm process at TSMC, with a massive 21,100 million transistors on an 815 mm² die. This results in a transistor density of 25.9 million per mm². The AMD Radeon RX 7900 GRE uses the RDNA 3.0 architecture, also manufactured by TSMC, but on a much more advanced 5 nm process. It packs 57,700 million transistors into a smaller 529 mm² die, achieving a density of 109.1 million per mm². This is a four-fold increase in density, reflecting the newer manufacturing technology.

The memory subsystems are also fundamentally different. The TITAN V uses 12 GB of HBM2 memory on a 3072-bit bus, providing 651.3 GB/s of bandwidth. The RX 7900 GRE uses 16 GB of GDDR6 memory on a 256-bit bus, with a bandwidth of 576.0 GB/s. While the TITAN V has a wider bus and higher bandwidth, the RX 7900 GRE has more capacity and a faster effective memory speed of 18 Gbps versus 1696 Mbps. The GPU architectures also differ in their compute features: the TITAN V includes 640 Tensor Cores, while the RX 7900 GRE has 80 RT Cores for ray tracing. The TITAN V has no RT Cores, and the RX 7900 GRE has no Tensor Cores.

Specification Differences

The specification sheets reveal several key differences beyond the core architecture. The clock speeds are notably different: the TITAN V has a base clock of 1200 MHz and a boost of 1455 MHz, while the RX 7900 GRE has a base of 1287 MHz, a game clock of 1880 MHz, and a boost of 2245 MHz. This higher clock speed contributes to the AMD card's performance advantage in many tests. The shading units are identical at 5120, and the TMUs are also the same at 320. However, the ROPs differ significantly, with the TITAN V having 96 and the RX 7900 GRE having 160. This explains the AMD card's higher pixel rate of 359.2 GPixel/s versus 139.7 GPixel/s.

The power and interface specifications also differ. The TITAN V has a TDP of 250 W and requires a 6-pin and 8-pin power connector, while the RX 7900 GRE has a TDP of 260 W and requires two 8-pin connectors. Both have a suggested PSU of 600 W. The bus interface is different, with the TITAN V using PCIe 3.0 x16 and the RX 7900 GRE using PCIe 4.0 x16. Display outputs also differ: the TITAN V offers 1x HDMI 2.0 and 3x DisplayPort 1.4a, while the RX 7900 GRE offers 1x HDMI 2.1a, 2x DisplayPort 2.1, and 1x USB Type-C. The physical dimensions are close, with the TITAN V being 267 mm long, 112 mm high, and 40 mm wide, while the RX 7900 GRE is 276 mm long, 110 mm high, and 51 mm wide. Both are dual-slot cards. The API support shows the RX 7900 GRE supports DirectX 12 Ultimate (12_2), while the TITAN V is limited to DirectX 12 (12_1).
