NVIDIA T600 Mobile vs NVIDIA TITAN RTX Comparison

The NVIDIA T600 Mobile and NVIDIA TITAN RTX are both Turing-architecture GPUs from NVIDIA, but they occupy opposite ends of the performance and feature spectrum. The T600 Mobile is a low-power, integrated-format mobile part designed for portability and efficiency, while the TITAN RTX is a desktop behemoth aimed at professional visualization and compute. Benchmark data shows the TITAN RTX dominates in raw compute, but the two cards serve entirely different physical and thermal environments.

FAQ

Where Each One Wins

The T600 Mobile has no benchmark wins in the head-to-head comparison. The TITAN RTX wins both available tests decisively. However, the T600 Mobile’s advantages lie outside raw benchmark scores. Its 40 W TDP and lack of power connectors make it suitable for integrated-format systems where space and cooling are constrained. The TITAN RTX, by contrast, is a dual-slot card measuring 267 mm in length, requiring a 600 W suggested PSU.

In the broader performance context, the T600 Mobile’s average benchmark score of 32,849 places it in the 77th percentile of all GPUs, with rivals like the AMD Radeon RX 590 GME (32,601, +0.8%) and NVIDIA P104-100 (32,982, -0.4%). The TITAN RTX, despite its massive OpenCL and Vulkan scores, has a lower average benchmark score of 31,676 (76th percentile) because its average includes legacy Passmark tests where it scores poorly, such as 88 in DirectX 12 and 147 in DirectX 10. The TITAN RTX’s win condition is clearly in modern, compute-heavy workloads like Geekbench, where its 16.31 TFLOPS FP32 and 32.62 TFLOPS FP16 output overwhelm the T600 Mobile’s 2.527 TFLOPS FP32.

Architecture Differences

Both cards use the Turing architecture, but they are built on different chips. The T600 Mobile uses the TU117 chip, a small, energy-efficient die measuring 200 mm² with 4,700 million transistors. The TITAN RTX uses the TU102 chip, a massive 754 mm² die with 18,600 million transistors. This explains the enormous difference in shading units: the T600 Mobile has 896, while the TITAN RTX has 4,608.

The TITAN RTX includes dedicated RT cores (72) and tensor cores (576), which are absent from the T600 Mobile’s specification list. This makes the TITAN RTX capable of hardware-accelerated ray tracing and AI workloads, while the T600 Mobile relies on the base Turing shader pipeline. The texture and pixel rates follow the same pattern: the TITAN RTX delivers 509.8 GTexel/s and 169.9 GPixel/s, versus 78.96 GTexel/s and 45.12 GPixel/s for the T600 Mobile.

The memory architecture is another major divergence. The TITAN RTX’s 384-bit bus and 672.0 GB/s bandwidth are more than triple the T600 Mobile’s 128-bit bus and 192.0 GB/s. Both use GDDR6, but the TITAN RTX runs at 1750 MHz (14 Gbps effective) versus 1500 MHz (12 Gbps effective) for the T600 Mobile.

Specification Differences

The most obvious differences are in core configuration and memory. The TITAN RTX has 4,608 shading units, 288 TMUs, and 96 ROPs, compared to 896 shading units, 56 TMUs, and 32 ROPs on the T600 Mobile. Clock speeds also differ: the T600 Mobile has a base clock of 780 MHz and boost of 1410 MHz, while the TITAN RTX runs at 1350 MHz base and 1770 MHz boost.

Memory capacity is 4 GB versus 24 GB, with corresponding bus widths of 128-bit and 384-bit. The TITAN RTX also supports DirectX 12 Ultimate (12_2), while the T600 Mobile is limited to DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4. The TITAN RTX has a TDP of 280 W and requires dual-slot cooling with 2x 8-pin connectors, whereas the T600 Mobile is an integrated-format part (IGP) with a 40 W TDP and no power connectors.

Physical dimensions are only listed for the TITAN RTX: 267 mm length, 116 mm height, and 35 mm width. The T600 Mobile is described as "Portable Device Dependent" for display outputs, while the TITAN RTX offers 1x HDMI 2.0, 3x DisplayPort 1.4a, and 1x USB Type-C. The release dates differ significantly: the T600 Mobile launched in April 2021, while the TITAN RTX launched in December 2018.

Head-to-Head Benchmarks

The head-to-head data includes only two Geekbench tests, and the TITAN RTX wins both by overwhelming margins.

In Geekbench OpenCL, the TITAN RTX scores 144,858 against the T600 Mobile’s 35,486. The delta is -75.5% for the T600 Mobile, indicating that the TITAN RTX delivers approximately 4.08 times the compute performance. This is consistent with the FP32 throughput difference: 16.31 TFLOPS versus 2.527 TFLOPS, a factor of 6.45, though real-world OpenCL scaling is not perfectly linear.

In Geekbench Vulkan, the TITAN RTX scores 136,073 versus 30,211 for the T600 Mobile, a delta of -77.8%. This is a slightly larger gap than OpenCL, suggesting the TITAN RTX’s additional hardware features and higher bandwidth provide a proportionally greater advantage in Vulkan workloads. The TITAN RTX’s 672.0 GB/s memory bandwidth and 576 tensor cores likely contribute to this result.

The T600 Mobile’s average benchmark score of 32,849 is actually higher than the TITAN RTX’s average of 31,676, despite losing both head-to-head tests. This is because the TITAN RTX’s Passmark results are unusually low: 147 in DirectX 10, 189 in DirectX 11, 88 in DirectX 12, and 223 in DirectX 9. These legacy tests drag its average down, while the T600 Mobile’s two Geekbench scores are both above 30,000. The percentile rankings reflect this quirk: the T600 Mobile sits at the 77th percentile, one point above the TITAN RTX’s 76th percentile.

The Verdict

From the data, the TITAN RTX is the clear performance winner in compute benchmarks, offering roughly 4x the OpenCL and Vulkan scores of the T600 Mobile. Its 24 GB memory, 384-bit bus, and 16.31 TFLOPS FP32 make it a professional-grade compute card, and its RT and tensor cores add capabilities the T600 Mobile lacks entirely. For users who need maximum throughput in OpenCL or Vulkan, the TITAN RTX is the only choice between these two.

However, the T600 Mobile is not without a purpose. Its 40 W TDP and integrated format mean it can be installed in systems where a 280 W dual-slot card with a 600 W suggested PSU is physically impossible. The T600 Mobile’s 4 GB GDDR6 is sufficient for basic rendering or display tasks, and its 77th percentile ranking shows it holds its own against similarly positioned cards like the NVIDIA T550 Mobile (33,161, -0.9%) and AMD FirePro S9300 X2 (32,540, +0.9%).

The TITAN RTX’s average score being lower than the T600 Mobile’s is a statistical artifact of the Passmark legacy tests, not a reflection of real-world capability. In any modern compute workload, the TITAN RTX will massively outperform the T600 Mobile. The decision comes down to physical constraints: if a system can accommodate the TITAN RTX’s size and power draw, the data says it is vastly superior. If the system is a portable or embedded design, the T600 Mobile is the only viable option, and its benchmark scores are respectable for its class. The launch MSRP of the TITAN RTX was 2,499 USD, reinforcing its position as a high-end workstation product.
