Architecture Differences

The two NVIDIA cards come from different architectural generations and target very different use cases. The GeForce GTX TITAN X is built on the GM200 chip using Maxwell 2.0 architecture, fabricated on TSMC's 28 nm process. It packs 8,000 million transistors into a 601 mm² die, yielding a transistor density of 13.3M per mm². The P104-100, by contrast, uses the GP104 chip with Pascal architecture on a 16 nm process from the same foundry. It contains 7,200 million transistors on a much smaller 314 mm² die, achieving a higher density of 22.9M per mm².

The compute configurations differ substantially. The GTX TITAN X field 3072 shading units, 192 texture mapping units, and 96 raster output units. The P104-100 is more modest in raw unit counts, with 1920 shading units, 120 TMUs, and 64 ROPs. Neither card includes ray tracing or tensor cores, as those features did not exist in these architectures.

Clock speeds favor the Pascal part significantly. The P104-100 runs at a 1607 MHz base clock and 1733 MHz boost, while the GTX TITAN X operates at 1000 MHz base and 1089 MHz boost. Memory clocks also differ: the TITAN X uses 1753 MHz (7 Gbps effective) GDDR5, while the P104-100 runs GDDR5X at 1251 MHz (10 Gbps effective).

Memory configuration is a major architectural split. The GTX TITAN X carries 12 GB of GDDR5 on a 384-bit bus for 336.6 GB/s bandwidth. The P104-100 has only 4 GB of GDDR5X on a 256-bit bus, delivering 320.3 GB/s. The bus interface also diverges: the TITAN X uses PCIe 3.0 x16, while the P104-100 is limited to PCIe 1.0 x4, a clear indicator of its mining-oriented design.

The P104-100 has no display outputs at all, whereas the GTX TITAN X provides 1x DVI, 1x HDMI 2.0, and 3x DisplayPort 1.2. Power delivery reflects this too: the TITAN X requires 1x 6-pin plus 1x 8-pin connectors and a 600 W suggested PSU, while the P104-100 uses a single 8-pin with a 200 W suggested PSU. The TITAN X has a stated 250 W TDP; the P104-100 lists no TDP figure.

Head-to-Head Benchmarks

The database records two direct benchmark comparisons between these cards, and each wins one test. In Geekbench OpenCL, the NVIDIA P104-100 posts 52368 points against the GTX TITAN X's 41471. The delta of -20.8% is computed from the TITAN X's perspective, meaning the P104-100 outperforms it by roughly a fifth in this compute workload. This is a substantial margin and aligns with the Pascal architecture's higher clock speeds and improved compute efficiency.

In Geekbench Vulkan, the tables turn. The GTX TITAN X scores 49397, while the P104-100 manages 45165. The TITAN X leads by 9.4%, a solid but less dramatic victory. This suggests the Maxwell architecture, despite its older node and lower clocks, retains an advantage in Vulkan execution paths, possibly due to its larger memory capacity or different driver optimization profile.

The average benchmark scores place the TITAN X ahead overall: 36530 versus 32982, a difference of roughly 3548 points. That puts the TITAN X about 10.8% higher than the P104-100 in aggregate performance. However, the head-to-head results show that the choice of API matters greatly, and neither card dominates across all workloads.

FP16: not listed for the TITAN X, while the P104-100 shows 104.0 GFLOPS (1:64).

Power and connectivity differ as well. TDP: 250 W for the TITAN X, no listed TDP for the P104-100. Power connectors: 1x 6-pin + 1x 8-pin versus 1x 8-pin. Suggested PSU: 600 W versus 200 W. Bus interface: PCIe 3.0 x16 versus PCIe 1.0 x4. Display outputs: 1x DVI, 1x HDMI 2.0, 3x DisplayPort 1.2 versus no outputs. Dimensions: both are 267 mm long, but the TITAN X measures 111 mm in height and 38 mm in width, while the P104-100 lists no height or width data.

The TITAN X has a launch MSRP of 999 USD; the P104-100 has no launch MSRP recorded. Release dates: March 2015 for the TITAN X, December 2017 for the P104-100. The TITAN X belongs to the GeForce 900 generation, while the P104-100 is categorized under Mining GPUs.

Where Each One Wins

The NVIDIA P104-100 wins in raw compute throughput for OpenCL-style workloads. Its 20.8% advantage in Geekbench OpenCL, combined with a higher pixel rate (110.9 GPixel/s versus 104.5 GPixel/s) and nearly identical texture rate (208.0 versus 209.1 GTexel/s), makes it the stronger choice for compute-heavy tasks that leverage OpenCL. The higher boost clock of 1733 MHz and the GDDR5X memory at 10 Gbps effective also favor the Pascal card in memory-bandwidth-sensitive compute patterns.

The GTX TITAN X wins in Vulkan performance, posting a 9.4% higher score. Its 12 GB frame buffer is four times larger than the P104-100's 4 GB, which matters for workloads that exceed 4 GB of data residency. The 384-bit memory bus provides a wider path to memory, and the higher ROP count (96 versus 64) can benefit rasterization-heavy tasks. The TITAN X also has display outputs, making it usable for any visual output scenario, whereas the P104-100 cannot drive a monitor.

For API coverage, the TITAN X's higher average benchmark score (36530 versus 32982) and better percentile ranking (80th versus 77th) indicate broader overall capability. The P104-100's nearest rivals include mobile workstation cards like the T600 Mobile and T550 Mobile, while the TITAN X sits alongside desktop and mobile Radeon PRO parts. This positioning suggests the TITAN X competes in a higher performance tier.

The Verdict

The data supports a clear split based on use case. If the workload is compute-centric and uses OpenCL, the NVIDIA P104-100 is the superior part, delivering 20.8% higher performance in that specific benchmark. Its smaller die, higher clocks, and GDDR5X memory make it an efficient compute engine, and its lack of display outputs is irrelevant in a mining or headless compute environment.

If the workload involves Vulkan, or requires a display output, or needs more than 4 GB of memory, the NVIDIA GeForce GTX TITAN X is the correct choice. It wins the Vulkan test by 9.4%, offers 12 GB of GDDR5, provides full display connectivity, and holds a higher average benchmark score overall. The 999 USD launch MSRP reflects its premium positioning at release.

For a general-purpose GPU user, the TITAN X is the more versatile card due to its display outputs, larger memory pool, and higher aggregate benchmark average. For a specialized compute task that runs on OpenCL, the P104-100 delivers better raw numbers. The two cards split their head-to-head results evenly, so the deciding factors are API preference, memory capacity needs, and whether display output is required. The TITAN X's 80th percentile ranking versus the P104-100's 77th percentile confirms the former has slightly better standing across the full database of GPUs.
