NVIDIA GeForce GTX TITAN X vs NVIDIA RTX A1000 Mobile Comparison

The Verdict

The recorded data splits this comparison almost perfectly down the middle. In the OpenCL benchmark, the NVIDIA RTX A1000 Mobile scores 48703, which is 17.4% ahead of the NVIDIA GeForce GTX TITAN X’s 41471. In the Vulkan benchmark, the older GTX TITAN X fights back with a 49397 score, beating the RTX A1000 Mobile’s 46782 by 5.3%. Each card wins exactly one of the two recorded tests, so the choice depends entirely on which API workload matters more to the user.

For users running OpenCL-based compute tasks, the RTX A1000 Mobile is the clear pick. Its 48703 OpenCL score places it in the 85th percentile of all GPUs, and its average benchmark score of 47743 sits just 1.5% behind the AMD Radeon RX 6800 XT’s 48477. The GTX TITAN X, by contrast, lands in the 80th percentile with an average of 36530, nearly identical to the AMD Radeon RX 5300M’s 36529. For Vulkan-heavy applications, the GTX TITAN X’s 49397 is the stronger result, and it outperforms the RTX A1000 Mobile by a meaningful margin in that specific test.

The RTX A1000 Mobile suits modern, power-conscious systems where integrated form factor and current-generation feature support matter. The GTX TITAN X suits legacy desktop builds with ample power delivery and a preference for raw Vulkan throughput. Neither card dominates the other across the board, so the verdict is workload-dependent, not universal.

Where Each One Wins

NVIDIA RTX A1000 Mobile wins in OpenCL compute. The 48703 OpenCL score beats the GTX TITAN X’s 41471 by a substantial 17.4%. This advantage is consistent with the RTX A1000 Mobile’s architecture being optimized for parallel compute workloads, as its average benchmark score of 47743 is 30.7% higher than the GTX TITAN X’s 36530 average. The RTX A1000 Mobile also holds a higher overall percentile rank at 85 compared to the GTX TITAN X’s 80, indicating better standing across the full GPU database.

NVIDIA GeForce GTX TITAN X wins in Vulkan. The 49397 Vulkan score edges out the RTX A1000 Mobile’s 46782 by 5.3%. This is the only test where the GTX TITAN X leads, but it is a decisive lead. The GTX TITAN X also offers a much larger memory pool at 12 GB versus 4 GB, and a wider 384-bit memory bus versus 128-bit, which historically favors bandwidth-heavy workloads. However, the benchmark data only records the Vulkan win, so the memory advantage should be treated as a qualitative factor, not a tested result.

Rival context reinforces the split. The RTX A1000 Mobile’s nearest rivals in the database include the AMD Radeon RX 6800 XT (48477, -1.5% delta), AMD Radeon RX 6550M (46702, +2.2%), Intel Arc A530M (46614, +2.4%), and AMD Radeon RX 5600M (46601, +2.5%). The GTX TITAN X’s nearest rivals are the AMD Radeon RX 5300M (36529, 0% delta), NVIDIA T1000 (36289, +0.7%), AMD Radeon PRO W6400 (37157, -1.7%), and AMD Radeon Pro Duo (35860, +1.9%). The RTX A1000 Mobile sits near much faster company, while the GTX TITAN X clusters with mid-range modern cards.

Architecture Differences

The two GPUs come from completely different design eras. The RTX A1000 Mobile uses the GA107 chip built on Ampere architecture, manufactured on an 8 nm process at Samsung. It packs 8,700 million transistors into a 200 mm² die, yielding a transistor density of 43.5M per mm². The GTX TITAN X uses the GM200 chip on Maxwell 2.0 architecture, built on a 28 nm process at TSMC. It contains 8,000 million transistors spread across a much larger 601 mm² die, with a density of just 13.3M per mm². The RTX A1000 Mobile achieves more than triple the transistor density of the GTX TITAN X.

Core counts also differ significantly. The RTX A1000 Mobile has 2048 shading units, 64 texture mapping units, and 32 ROPs. It also includes 16 RT cores and 64 tensor cores, which are absent from the GTX TITAN X entirely. The GTX TITAN X counters with 3072 shading units, 192 TMUs, and 96 ROPs. In raw pixel and texture rates, the GTX TITAN X leads with 104.5 GPixel/s and 209.1 GTexel/s versus 36.48 GPixel/s and 72.96 GTexel/s for the RTX A1000 Mobile. However, the RTX A1000 Mobile’s FP32 compute of 4.669 TFLOPS is lower than the GTX TITAN X’s 6.691 TFLOPS, and the RTX A1000 Mobile supports FP16 at 4.669 TFLOPS (1:1) while the GTX TITAN X has no recorded FP16 capability.

Memory configurations reflect their target markets. The RTX A1000 Mobile uses 4 GB of GDDR6 on a 128-bit bus, delivering 176.0 GB/s bandwidth at 1375 MHz (11 Gbps effective). The GTX TITAN X uses 12 GB of GDDR5 on a 384-bit bus, delivering 336.6 GB/s bandwidth at 1753 MHz (7 Gbps effective). The GTX TITAN X has roughly double the memory bandwidth and triple the memory capacity.

Clock speeds and power profiles differ dramatically. The RTX A1000 Mobile runs at a base of 630 MHz and boosts to 1140 MHz, with a 60 W TDP and no power connectors, designed as an integrated graphics processor (IGP). The GTX TITAN X runs at a base of 1000 MHz and boosts to 1089 MHz, with a 250 W TDP, dual-slot cooler, and 1x 6-pin plus 1x 8-pin power connectors, requiring a 600 W suggested PSU. The GTX TITAN X also has a physical footprint of 267 mm length, 111 mm height, and 38 mm width, while the RTX A1000 Mobile’s dimensions are not recorded.

API support shows the generational gap. The RTX A1000 Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The GTX TITAN X supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The RTX A1000 Mobile’s DirectX 12_2 support is newer and includes features the Maxwell architecture cannot offer. The bus interface also differs: PCIe 4.0 x8 for the RTX A1000 Mobile versus PCIe 3.0 x16 for the GTX TITAN X.

Head-to-Head Benchmarks

The recorded head-to-head data contains two benchmark tests: Geekbench OpenCL and Geekbench Vulkan. Each GPU wins one test, and the margins tell a clear story about their respective strengths.

Geekbench OpenCL: RTX A1000 Mobile wins by 17.4%. The RTX A1000 Mobile scores 48703 against the GTX TITAN X’s 41471. This is the largest margin in either direction. The 17.4% delta is substantial in GPU terms, and it aligns with the RTX A1000 Mobile’s higher overall average score. In the database, the RTX A1000 Mobile’s 48703 OpenCL result is close to the AMD Radeon RX 6800 XT’s 48477 average, which suggests the mobile chip punches well above its power class in compute workloads. The GTX TITAN X’s 41471 OpenCL score is below its own Vulkan score, indicating that Maxwell’s compute path is less efficient in this API.

Geekbench Vulkan: GTX TITAN X wins by 5.3%. The GTX TITAN X scores 49397, while the RTX A1000 Mobile scores 46782. The delta is 5.3% in favor of the older card. This result is notable because the GTX TITAN X lacks modern feature support like RT cores and tensor cores, yet it still outperforms the Ampere chip in Vulkan. The GTX TITAN X’s Vulkan score of 49397 is actually its strongest recorded benchmark, higher than its OpenCL score of 41471 by 19.2%. The RTX A1000 Mobile’s Vulkan score of 46782 is slightly lower than its OpenCL score of 48703, a 4.1% gap.

Net result: a 1-1 split. The wins are balanced, but the magnitudes differ. The RTX A1000 Mobile’s OpenCL win is 17.4%, which is more than three times larger than the GTX TITAN X’s Vulkan win of 5.3%. This asymmetry matters for users who weight compute performance more heavily. The average benchmark score also favors the RTX A1000 Mobile at 47743 versus 36530, a 30.7% advantage that reflects the mobile chip’s consistency across both tests.

The head-to-head data also shows that both GPUs perform within their expected rival clusters. The RTX A1000 Mobile’s 48703 OpenCL score puts it just 1.5% behind the AMD Radeon RX 6800 XT’s average of 48477, which is a high-end desktop card. The GTX TITAN X’s 49397 Vulkan score, if compared to its nearest rivals, would place it well above the AMD Radeon RX 5300M’s average of 36529, though the database does not record a Vulkan-specific rival comparison. What is clear from the numbers: the RTX A1000 Mobile is the better all-around compute card, while the GTX TITAN X retains a specific edge in Vulkan rendering workloads.
