NVIDIA T400 vs NVIDIA TITAN Xp Comparison

Head-to-Head Benchmarks

The benchmark data presents a stark contrast between these two NVIDIA offerings. Across the two shared tests, the NVIDIA TITAN Xp claims victory in both, with margins that border on the categorical. In the Geekbench OpenCL test, the TITAN Xp records 72,585 points against the T400's 17,039, a difference of 326 percent. The Vulkan test widens the gap further: the TITAN Xp scores 87,180 while the T400 manages 15,976, translating to a 445.7 percent advantage. These are not close contests; they are generational and architectural chasms.

The TITAN Xp's average benchmark score across all recorded tests sits at 19,177, placing it in the 64th percentile of all GPUs in the database. Its nearest rivals in the aggregate ranking include the NVIDIA GeForce GTX 780 (19,164, a delta of 0.1 percent), the NVIDIA Tesla K20m (19,089, a delta of 0.5 percent), the NVIDIA GeForce RTX 4050 Mobile (19,049, a delta of 0.7 percent), and the AMD Radeon RX 6600 (19,036, a delta of 0.7 percent). The TITAN Xp effectively trades blows with these cards in the overall average, despite its massive individual test victories.

The T400, by contrast, posts an average benchmark score of 16,508, which lands it in the 60th percentile of all GPUs. Its nearest rivals are the NVIDIA GeForce RTX 5090 D V2 (16,504, a delta of 0 percent), the AMD Radeon PRO W7500 (16,415, a delta of 0.6 percent), the NVIDIA RTX PRO 6000 Blackwell (16,408, a delta of 0.6 percent), and the AMD Radeon RX 5700 XT (16,361, a delta of 0.9 percent). The T400 is essentially neck-and-neck with these competitors in the aggregate, which is notable given its modest specifications.

The head-to-head results are unambiguous: the TITAN Xp is 326 percent faster in OpenCL and 445.7 percent faster in Vulkan. These deltas are so large that they suggest the T400 is not competing in the same performance tier at all. The TITAN Xp's raw compute throughput, as expressed in its FP32 rating of 12.15 TFLOPS, dwarfs the T400's 1,094.4 GFLOPS. When a card offers more than eleven times the floating-point throughput, benchmark outcomes follow predictably.

FAQ

The Verdict

The data points to a clear conclusion for users deciding between these two cards. The NVIDIA TITAN Xp is categorically faster in every shared benchmark, with margins ranging from 326 percent to 445.7 percent. Its FP32 throughput of 12.15 TFLOPS, memory bandwidth of 547.6 GB/s, and 12 GB of GDDR5X memory make it a compute powerhouse relative to the T400.

The T400, meanwhile, is a low-power professional card. Its 30 W TDP, single-slot design, and lack of power connectors indicate a different use case entirely. It offers 2 GB of GDDR6 memory on a 64-bit bus, delivering 80.00 GB/s of bandwidth. Its FP32 output of 1,094.4 GFLOPS is a fraction of the TITAN Xp's capability.

Users who need raw compute performance, high-resolution texture work, or substantial memory bandwidth should select the TITAN Xp. Its 384-bit memory bus and 96 ROPs provide the infrastructure for demanding workloads. Users who require a low-profile, low-power card for basic display output, legacy applications, or constrained physical environments may find the T400 adequate, but they must accept a massive performance compromise.

The recorded data shows no scenario where the T400 outperforms the TITAN Xp. The TITAN Xp's average benchmark score of 19,177 versus the T400's 16,508 reinforces this hierarchy, even though the percentile rankings are closer than the raw head-to-head deltas suggest.

Specification Differences

The two cards diverge across nearly every measurable specification. The TITAN Xp uses a 16 nm process node, while the T400 uses a 12 nm node. The TITAN Xp houses 11,800 million transistors on a 471 mm² die, whereas the T400 contains 4,700 million transistors on a 200 mm² die. Transistor density measures 25.1M per mm² for the TITAN Xp and 23.5M per mm² for the T400.

Clock speeds differ substantially. The TITAN Xp runs a base clock of 1405 MHz and a boost clock of 1582 MHz. The T400 operates at a 420 MHz base and 1425 MHz boost. Memory clocks also differ: the TITAN Xp uses 1426 MHz memory with an effective 11.4 Gbps data rate, while the T400 uses 1250 MHz memory with 10 Gbps effective.

Memory configuration is a major differentiator. The TITAN Xp offers 12 GB of GDDR5X on a 384-bit bus, yielding 547.6 GB/s of bandwidth. The T400 offers 2 GB of GDDR6 on a 64-bit bus, yielding 80.00 GB/s. The TITAN Xp has 3840 shading units, 240 texture mapping units, and 96 ROPs. The T400 has 384 shading units, 24 TMUs, and 16 ROPs.

Pixel and texture rates follow suit. The TITAN Xp achieves 151.9 GPixel/s and 379.7 GTexel/s. The T400 achieves 22.80 GPixel/s and 34.20 GTexel/s. The TITAN Xp's FP32 output is 12.15 TFLOPS with FP16 at 189.8 GFLOPS (1:64 ratio). The T400's FP32 output is 1,094.4 GFLOPS with FP16 at 2.189 TFLOPS (2:1 ratio).

Power and physical specifications diverge completely. The TITAN Xp has a 250 W TDP, uses a dual-slot design, requires a 1x 6-pin plus 1x 8-pin power connector setup, and recommends a 600 W power supply. The T400 has a 30 W TDP, uses a single-slot design, requires no power connectors, and recommends a 200 W power supply. The TITAN Xp measures 267 mm in length, 112 mm in height, and 40 mm in width; the T400 has no recorded dimensions.

Display outputs also differ: the TITAN Xp provides 1x HDMI 2.0 and 3x DisplayPort 1.4a, while the T400 provides 3x mini-DisplayPort 1.4a. Both use PCIe 3.0 x16 interfaces.

Architecture Differences

The TITAN Xp is built on the Pascal architecture, specifically the GP102 chip, and belongs to the GeForce 10 generation. The T400 is built on the Turing architecture, specifically the TU117 chip, and belongs to the Quadro Turing (Tx000) generation. Both are manufactured by TSMC, but on different nodes: the TITAN Xp uses 16 nm, the T400 uses 12 nm.

The transistor counts reflect the architectural gulf. The TITAN Xp packs 11,800 million transistors, while the T400 contains 4,700 million. Die size also differs: 471 mm² for the TITAN Xp versus 200 mm² for the T400. Neither card features ray tracing cores or tensor cores, so those aspects are identical.

The FP16 capabilities reveal a fundamental architectural shift. The TITAN Xp delivers FP16 at 189.8 GFLOPS with a 1:64 ratio, meaning FP16 throughput is severely limited relative to FP32. The T400 delivers FP16 at 2.189 TFLOPS with a 2:1 ratio, meaning FP16 is actually faster than FP32. This reflects Turing's improved mixed-precision handling compared to Pascal.

Memory technology also differs by architecture generation. The TITAN Xp uses GDDR5X, while the T400 uses GDDR6. The TITAN Xp's memory clock of 1426 MHz with 11.4 Gbps effective data rate exceeds the T400's 1250 MHz with 10 Gbps effective, but the T400's GDDR6 is a newer memory standard.

Both cards support DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical. The production status for both is end-of-life. The TITAN Xp was released on April 5, 2017, with its predecessor being GeForce 900 and successor being GeForce 20. The T400 was released on May 5, 2021, with its predecessor being Quadro Volta and successor being Workstation Ampere.

The architectural differences explain the benchmark results. Pascal's GP102 was designed for maximum rasterization throughput and compute density, evidenced by its 3840 shading units and 96 ROPs. Turing's TU117 was designed for efficiency and professional display capabilities, evidenced by its 384 shading units and 16 ROPs. The TITAN Xp's 547.6 GB/s memory bandwidth versus the T400's 80.00 GB/s further underscores the performance hierarchy. The recorded data confirms that architectural intent translates directly into benchmark outcomes.
