NVIDIA RTX A4000 Mobile vs NVIDIA TITAN Xp Comparison

Where Each One Wins

The recorded benchmark data splits these two NVIDIA cards along clear generational and architectural lines. The NVIDIA RTX A4000 Mobile claims a single, dominant victory in Geekbench OpenCL, while the NVIDIA TITAN Xp sweeps the remaining eight head-to-head tests. This is not a close contest in terms of win count, but the margin of victory in that one OpenCL result is substantial enough to warrant attention.

The RTX A4000 Mobile wins the Geekbench OpenCL test with a score of 97,178 against the TITAN Xp's 72,585, a 33.9% advantage. This is the only test where the newer Ampere architecture overcomes the older Pascal design. The data suggests this win stems from compute-heavy workloads that leverage the RTX A4000 Mobile's 5,120 shading units and 160 tensor cores, features the TITAN Xp lacks entirely. OpenCL often rewards raw parallel throughput, and the A4000 Mobile's 17.20 TFLOPS FP32 output exceeds the TITAN Xp's 12.15 TFLOPS, which aligns with this result.

Every other benchmark favors the TITAN Xp. The Geekbench Vulkan test shows the TITAN Xp at 87,180 versus 73,002 for the RTX A4000 Mobile, a 16.3% lead. The DirectX legacy tests all go to the TITAN Xp as well: DirectX 9 (226 vs 157, a 30.5% gap), DirectX 10 (119 vs 105, an 11.8% gap), DirectX 11 (152 vs 127, a 16.4% gap), and DirectX 12 (69 vs 66, a 4.3% gap). The Passmark G2D test also favors the TITAN Xp (883 vs 585, a 33.7% gap), as does the Passmark GPU Compute test (9,430 vs 6,394, a 32.2% gap). The largest single-score difference comes in Passmark G3D, where the TITAN Xp scores 18,750 against 14,796, a 21.1% lead.

The pattern is telling: the TITAN Xp dominates rasterization, legacy API performance, and even compute under Passmark's test methodology. The RTX A4000 Mobile only wins where its newer architecture and higher shader count can express themselves through OpenCL's compute model. For general graphics work, the TITAN Xp is the clear winner. For specific compute tasks, the A4000 Mobile shows a meaningful edge.

The Verdict

The data points to a simple conclusion: the NVIDIA TITAN Xp is the stronger overall performer in this head-to-head, winning 8 of 9 benchmarks. Its average benchmark score of 19,177 slightly trails the RTX A4000 Mobile's 21,379, but that average is dragged down by the single large OpenCL loss. The TITAN Xp's percentile ranking of 64 versus the A4000 Mobile's 66 is close, but the win distribution tells the real story.

Users prioritizing legacy DirectX performance, rasterization throughput, or general GPU compute under Passmark should choose the TITAN Xp. Its margins in DirectX 9, G2D, and GPU Compute are substantial, ranging from 30.5% to 33.7%. The TITAN Xp also offers 12 GB of GDDR5X memory versus the A4000 Mobile's 8 GB of GDDR6, and its memory bandwidth of 547.6 GB/s far exceeds the A4000 Mobile's 384.0 GB/s. For workloads that saturate memory bandwidth, this difference is decisive.

Users whose workloads rely heavily on OpenCL compute should consider the RTX A4000 Mobile. Its 33.9% advantage in that specific test is not trivial, and its 17.20 TFLOPS FP32 output is 41.6% higher than the TITAN Xp's 12.15 TFLOPS. The A4000 Mobile also supports DirectX 12 Ultimate (12_2) and includes 40 RT cores and 160 tensor cores, features entirely absent from the TITAN Xp. If ray tracing or tensor-accelerated workloads are part of the usage profile, the A4000 Mobile is the only option with those capabilities.

The TITAN Xp is a dual-slot card requiring 1x 6-pin and 1x 8-pin power connectors with a 250 W TDP. The RTX A4000 Mobile is a mobile part with a 115 W TDP and no power connectors, making it suitable for portable systems. The choice depends on form factor and workload: desktop users with legacy API needs should pick the TITAN Xp, while mobile users with OpenCL compute or ray tracing needs should pick the A4000 Mobile.

Head-to-Head Benchmarks

The Geekbench OpenCL result is the largest margin in either direction. The RTX A4000 Mobile scores 97,178, beating the TITAN Xp's 72,585 by 33.9%. This is the only benchmark where the A4000 Mobile leads, and the gap is wide enough to suggest a fundamental architectural advantage in compute-heavy OpenCL workloads. The A4000 Mobile's 5,120 shading units and 160 tensor cores likely drive this result.

The Geekbench Vulkan test reverses the outcome. The TITAN Xp scores 87,180 versus 73,002, a 16.3% lead. Vulkan's lower-level API may favor the TITAN Xp's higher clock speeds (1,405 MHz base, 1,582 MHz boost versus 1,140 MHz and 1,680 MHz for the A4000 Mobile) and its 240 texture mapping units against the A4000 Mobile's 160.

Passmark's legacy DirectX tests show consistent TITAN Xp advantages. DirectX 9 is the most lopsided: 226 versus 157, a 30.5% gap. DirectX 10 shows 119 versus 105, an 11.8% gap. DirectX 11 shows 152 versus 127, a 16.4% gap. DirectX 12 is the closest test overall, with the TITAN Xp at 69 and the A4000 Mobile at 66, a mere 4.3% gap. This narrow margin in the newest API suggests the A4000 Mobile's Ampere architecture is more competitive in modern rendering paths.

Passmark G2D heavily favors the TITAN Xp: 883 versus 585, a 33.7% gap. This 2D performance test likely benefits from the TITAN Xp's higher pixel rate of 151.9 GPixel/s versus the A4000 Mobile's 134.4 GPixel/s. Passmark G3D shows the TITAN Xp at 18,750 against 14,796, a 21.1% lead, reflecting its superior rasterization throughput.

Passmark GPU Compute gives the TITAN Xp another decisive win: 9,430 versus 6,394, a 32.2% gap. This is notable because it contradicts the OpenCL result. The Passmark compute test likely uses a different workload profile than Geekbench OpenCL, and the TITAN Xp's higher texture rate of 379.7 GTexel/s versus 268.8 GTexel/s may play a role. The data suggests that "compute" is not a single category; different test methodologies produce opposite winners.
