AMD Radeon RX 6800M vs NVIDIA TITAN V Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive sweep: the NVIDIA TITAN V wins all ten head-to-head benchmark comparisons against the AMD Radeon RX 6800M. The largest margin appears in the compute-oriented Passmark GPU Compute test, where the TITAN V scores 9,263 versus 5,032, a delta of 84.1%. That is the single biggest performance gap in this comparison, and it underscores how far apart these two GPUs are in raw computational throughput.

The second-largest win comes from Geekbench OpenCL, where the TITAN V posts 157,265 against 87,621, a 79.5% advantage. This result aligns with the TITAN V's much higher FP32 and FP16 figures in the specification sheet: 14.90 TFLOPS versus 12.24 TFLOPS for FP32, and 29.80 TFLOPS versus 24.47 TFLOPS for FP16. The gap is greater in compute workloads than in gaming-oriented tests, which suggests the TITAN V's architecture is particularly well-suited to general-purpose GPU tasks.

In the 3DMark Steel Nomad DX12 test, the TITAN V scores 3,565 against 2,238, a 59.3% lead. This is a modern DirectX 12 workload, and the TITAN V still holds a commanding edge despite being released several years earlier. The Geekbench Vulkan result follows a similar pattern: 152,117 versus 94,766, a 60.5% delta. Both APIs show consistent margins, indicating the TITAN V's advantage is not limited to one specific graphics interface.

The Passmark DirectX 9 test shows a 44.9% lead for the TITAN V (213 versus 147), while DirectX 10 shows 51.5% (153 versus 101). DirectX 11 shows the narrowest margin in the entire comparison at 19.7% (152 versus 127), and DirectX 12 shows 24.6% (81 versus 65). These older API tests suggest the TITAN V maintains its lead across legacy workloads, though the magnitude varies. The Passmark G3D score, which aggregates overall 3D graphics performance, gives the TITAN V a 49.3% advantage (19,805 versus 13,261).

The 2D performance gap is also substantial: Passmark G2D shows 937 versus 538, a 74.2% delta. This is notable because 2D performance is often less dependent on raw shader throughput and more on memory bandwidth, pixel fill, and driver overhead. The TITAN V's HBM2 memory with 651.3 GB/s bandwidth compared to the RX 6800M's GDDR6 at 384.0 GB/s likely explains much of this difference.

Where Each One Wins

The data is unambiguous: the NVIDIA TITAN V wins every benchmark in the comparison set, so there are no test categories where the AMD Radeon RX 6800M comes out ahead. However, the magnitude of the TITAN V's advantage varies by workload type, which provides useful context.

For compute-heavy applications, the TITAN V is overwhelmingly dominant. The 84.1% lead in Passmark GPU Compute and the 79.5% lead in Geekbench OpenCL are the two largest margins in the entire dataset. The TITAN V's 640 tensor cores and 5,120 shading units give it a massive parallel-processing advantage over the RX 6800M's 2,560 shading units and 40 ray accelerators. Any workload that relies on FP32 or FP16 math will strongly favor the TITAN V.

For 2D and legacy 3D workloads, the TITAN V also wins by wide margins. The 74.2% lead in Passmark G2D suggests that memory bandwidth plays a significant role, as the TITAN V's 651.3 GB/s is 70% higher than the RX 6800M's 384.0 GB/s. The DirectX 9 and DirectX 10 tests show 44.9% and 51.5% leads respectively, which likely reflect the TITAN V's higher pixel rate (139.7 GPixel/s versus 153.0 GPixel/s for the RX 6800M, though the RX 6800M actually has a higher pixel rate; the TITAN V's advantage here must come from other factors such as driver optimization or memory bandwidth).

For modern DirectX 12 workloads, the TITAN V still wins but by a slightly smaller margin. The 3DMark Steel Nomad test shows 59.3%, and Passmark DirectX 12 shows 24.6%. The RX 6800M supports DirectX 12 Ultimate (12_2), while the TITAN V only supports DirectX 12 (12_1), so the RX 6800M has access to newer feature sets. Despite this, the TITAN V's raw compute power overcomes the feature-level disadvantage in these specific tests.

Architecture Differences

The NVIDIA TITAN V is built on the Volta architecture with the GV100 chip, part of the GeForce 10 generation. It includes 640 tensor cores, which are specialized for deep learning and matrix math operations. The RX 6800M uses the RDNA 2.0 architecture with the Navi 22 chip, part of the Radeon RX 6000 series. It includes 40 ray accelerators, which handle real-time ray tracing workloads.

The API support differs: the TITAN V supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The RX 6800M supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The DirectX 12_2 support on the RX 6800M enables features like mesh shaders and variable rate shading, which the TITAN V cannot access.

The memory architecture is fundamentally different. The TITAN V uses HBM2 on a 3072-bit bus with 651.3 GB/s bandwidth, while the RX 6800M uses GDDR6 on a 192-bit bus with 384.0 GB/s. Both have 12 GB of memory, but the TITAN V's wider bus gives it substantially more bandwidth. The RX 6800M compensates with higher clock speeds. The RX 6800M was released on 2021-05-30, while the TITAN V was released on 2017-12-06. The TITAN V's predecessor was GeForce 900 and its successor was GeForce 20. The RX 6800M's predecessor was Polaris Mobile and it has no listed successor.

The Verdict

The benchmark data is clear: the NVIDIA TITAN V is the stronger GPU in every measured test. It wins all ten head-to-head comparisons, with deltas ranging from 19.7% in Passmark DirectX 11 to 84.1% in Passmark GPU Compute. The TITAN V's average benchmark score of 34,355 places it in the 79th percentile of all GPUs, while the RX 6800M's 28,874 places it in the 74th percentile. The TITAN V's nearest rivals in the database are the NVIDIA RTX A1000 (34,207, 0.4% delta) and the AMD Radeon HD 7970 (34,541, -0.5% delta). The RX 6800M's nearest rivals are the AMD Radeon RX 570 (28,766, 0.4% delta) and the Intel Arc A370M (29,175, -1% delta).

For users prioritizing compute performance, the TITAN V is the obvious choice. Its 84.1% lead in GPU compute and 79.5% lead in OpenCL make it far superior for tasks like scientific simulation, machine learning inference, and video rendering. The 640 tensor cores provide an additional capability that the RX 6800M entirely lacks.

For users prioritizing modern graphics features, the RX 6800M has advantages in its specification sheet. It supports DirectX 12 Ultimate (12_2), has ray accelerator hardware, runs at much higher clock speeds, and uses a smaller 7 nm process with lower power consumption (145 W versus 250 W). However, the recorded benchmark data shows that these feature advantages do not translate into higher scores in the tested workloads. The TITAN V still wins all DirectX 12 tests, even though the RX 6800M supports a newer version of the API.

Given the benchmark results, the NVIDIA TITAN V should be selected by users who need maximum compute throughput and can accommodate a 250 W TDP with dual-slot cooling. The AMD Radeon RX 6800M should be selected by users who need a lower-power solution with modern DirectX 12 Ultimate features and ray tracing support, provided they accept a significant performance deficit in every measured benchmark. The data does not support choosing the RX 6800M based on performance alone.
