NVIDIA RTX A3000 Mobile vs NVIDIA TITAN X Pascal Comparison

The NVIDIA TITAN X Pascal and NVIDIA RTX A3000 Mobile represent two distinct eras of GPU design, separated by five years of architectural evolution. The benchmark data reveals a fascinating split: the mobile Ampere part dominates in OpenCL compute, while the desktop Pascal flagship fights back decisively in Vulkan. Their average benchmark scores are remarkably close—72,098 for the TITAN X against 70,140 for the A3000 Mobile—yet the way they achieve those numbers could not be more different.

Head-to-Head Benchmarks

The Geekbench OpenCL test delivers a clear victory to the RTX A3000 Mobile. It scores 79,091 against the TITAN X Pascal’s 66,696, a delta of -15.7% from the desktop card’s perspective. That is a substantial 12,395-point gap, representing an 18.6% advantage for the mobile chip. The data suggests the A3000’s compute architecture, with its higher shading unit count of 4,096 versus 3,584, translates directly into raw OpenCL throughput that the older Pascal design cannot match despite its higher clock speeds.

The Vulkan test flips the script entirely. Here, the TITAN X Pascal scores 77,499, while the RTX A3000 Mobile manages only 61,189. The deltaPct of 26.7% in favor of the TITAN X is even more lopsided than the OpenCL result, showing a 16,310-point advantage. This is a striking divergence—the same two GPUs trading blows with opposite outcomes depending on the API. The TITAN X’s victory in Vulkan likely stems from its massive texture and pixel throughput rates, which are 342.9 GTexel/s and 147.0 GPixel/s respectively, dwarfing the A3000’s 157.4 GTexel/s and 78.72 GPixel/s.

With one win apiece, the head-to-head record is tied at 1-1. The average benchmark scores tell a similar story of near-parity: the TITAN X sits at 72,098, and the A3000 trails by only 1,958 points. Relative to their nearest rivals, both GPUs land in the 91st percentile of all GPUs. The TITAN X’s closest competitor is the AMD Radeon Pro Vega 64, which scores 72,379 and edges ahead by a razor-thin 0.4%. The A3000’s nearest rival, the NVIDIA Quadro P6000, scores 69,986, just 0.2% behind. These margins are almost noise-level, underscoring how tightly grouped this performance tier has become.

Architecture Differences

The fundamental divide lies in process technology and transistor density. The TITAN X Pascal uses a 16 nm TSMC node, packing 11,800 million transistors onto a 471 mm² die for a density of 25.1M per mm². The RTX A3000 Mobile moves to Samsung’s 8 nm process, fitting 17,400 million transistors into a smaller 392 mm² die, achieving 44.4M per mm²—a 76.9% improvement in density. This explains how the mobile chip crams more shading units (4,096 vs 3,584) into a physically smaller package while consuming far less power.

Clock speeds tell a story of power envelope trade-offs. The TITAN X runs at a 1417 MHz base and 1531 MHz boost, while the A3000 operates at a lowly 600 MHz base and 1230 MHz boost. The Pascal card’s higher clocks push its FP32 performance to 10.97 TFLOPS, narrowly ahead of the A3000’s 10.08 TFLOPS. Yet the A3000 achieves this with a 70 W TDP against the TITAN X’s 250 W—a 3.6x efficiency advantage that the clock speeds alone do not reveal.

Memory configurations diverge sharply. The TITAN X offers 12 GB of GDDR5X on a 384-bit bus, delivering 480.4 GB/s of bandwidth. The A3000 halves capacity to 6 GB of GDDR6 on a 192-bit bus, with bandwidth dropping to 264.0 GB/s. However, the A3000’s memory runs at 11 Gbps effective versus 10 Gbps, slightly offsetting its narrower interface. The A3000 also introduces dedicated RT cores (32) and Tensor cores (128), features entirely absent from the Pascal chip. Its FP16 throughput of 10.08 TFLOPS matches FP32 at a 1:1 ratio, whereas the TITAN X’s FP16 is a token 171.5 GFLOPS at a 1:64 ratio—a 58.8x difference in half-precision capability.

Where Each One Wins

The RTX A3000 Mobile is the clear winner in OpenCL-centric workloads. Its 4,096 shading units and 1:1 FP16 ratio make it better suited for compute tasks that leverage half-precision arithmetic, common in AI inference and certain scientific simulations. The mobile card’s 128 Tensor cores further cement its advantage in machine learning applications, even if the benchmark data only directly measures OpenCL and Vulkan. Its 70 W power envelope also means it can sustain performance in thermally constrained environments, a critical factor for laptop deployments.

The TITAN X Pascal dominates in Vulkan-based rendering and rasterization. Its 224 TMUs and 96 ROPs, combined with a 384-bit memory bus, provide the raw fill rates needed for high-resolution texture mapping and pixel throughput. The 147.0 GPixel/s pixel rate is nearly double the A3000’s 78.72 GPixel/s, giving the older card a decisive edge in traditional graphics workloads that do not leverage ray tracing or tensor operations. Its 12 GB VRAM also offers more headroom for large textures and datasets, where the A3000’s 6 GB could become a bottleneck.

The PCIe interface difference matters for data transfer. The TITAN X uses PCIe 3.0 x16, while the A3000 supports PCIe 4.0 x16, potentially offering double the host bandwidth for GPU-to-CPU communication. This favors the mobile chip in workloads that stream data frequently, such as some professional visualization tasks.

The Verdict

The data points to a clear split based on use case rather than a single overall winner. For compute-heavy OpenCL workloads, the RTX A3000 Mobile is the superior choice—its 15.7% lead in that benchmark, combined with 128 Tensor cores and matching FP16/FP32 throughput, makes it the more future-proof option for AI and scientific tasks. The 70 W TDP is a secondary advantage, enabling deployment in mobile systems where the TITAN X’s 250 W draw would be impossible.

For Vulkan-based gaming or graphics rendering, the TITAN X Pascal retains a decisive 26.7% advantage. The higher pixel rate of 147.0 GPixel/s and texture rate of 342.9 GTexel/s, along with double the VRAM capacity at 12 GB versus 6 GB, give it the edge in traditional rasterization. Its 1,199 USD launch MSRP reflects its original high-end desktop positioning, though production status is now end-of-life.

The near-identical average scores—within 2.8% of each other—suggest that for mixed workloads, users would notice little difference. The choice hinges on whether the workload leans toward compute (choose the A3000) or graphics (choose the TITAN X). The A3000’s 8 nm process and PCIe 4.0 interface indicate a more modern foundation, but the TITAN X’s raw fill rates remain formidable even against a five-years-newer architecture.

Specification Differences

The two GPUs differ across nearly every major specification category. The TITAN X uses the GP102 chip on a 16 nm TSMC process, while the A3000 employs GA104 on Samsung’s 8 nm node. Transistor counts are 11,800 million versus 17,400 million, with die sizes of 471 mm² and 392 mm² respectively. Clock speeds differ substantially: the TITAN X runs at 1417/1531 MHz base/boost, while the A3000 operates at 600/1230 MHz.

Memory specifications diverge completely. The TITAN X has 12 GB of GDDR5X with a 384-bit bus and 480.4 GB/s bandwidth; the A3000 has 6 GB of GDDR6 with a 192-bit bus and 264.0 GB/s. Shading units favor the A3000 at 4,096 versus 3,584, but TMUs and ROPs favor the TITAN X at 224 and 96 versus 128 and 64. The A3000 adds 32 RT cores and 128 Tensor cores, which the TITAN X lacks entirely. FP32 performance is close (10.97 vs 10.08 TFLOPS), but FP16 shows a massive gap: 171.5 GFLOPS for the TITAN X versus 10.08 TFLOPS for the A3000.

Power and physical specifications highlight their different target platforms. The TITAN X draws 250 W, requires dual-slot cooling, and uses 1x 6-pin plus 1x 8-pin power connectors with a 600 W suggested PSU. The A3000 sips 70 W, needs no external power connectors, and has no suggested PSU. The TITAN X measures 267 mm in length, while the A3000 reports no dimensions as a mobile component. Bus interfaces are PCIe 3.0 x16 versus PCIe 4.0 x16, and display outputs are 1x DVI, 1x HDMI 2.0, 3x DisplayPort 1.4a for the desktop card, versus portable-device-dependent outputs for the mobile chip. Finally, DirectX support is 12_1 for Pascal and 12 Ultimate (12_2) for Ampere, with both sharing OpenGL 4.6 and Vulkan 1.4 support.
