NVIDIA GeForce RTX 2060 vs NVIDIA T400 4 GB Comparison

NVIDIA T400 4 GB and NVIDIA GeForce RTX 2060 are both built on the Turing architecture, but they occupy very different positions in NVIDIA’s lineup. The T400 is a 30 W single-slot workstation card with 4 GB of GDDR6, while the RTX 2060 is a 160 W dual-slot consumer card with 6 GB of GDDR6 and dedicated ray tracing and tensor cores. Benchmark data from the FACT PACK shows only two common tests between them, and in both, the RTX 2060 dominates by a wide margin, though the T400’s efficiency profile and workstation heritage give it a distinct role.

Head-to-Head Benchmarks

The head-to-head results are stark. In Geekbench OpenCL, the RTX 2060 scores 65,014 against the T400’s 17,320, a delta of -73.4% from the T400’s perspective. This means the RTX 2060 delivers roughly 3.75 times the raw compute throughput in this workload. The gap is even larger in Geekbench Vulkan: the RTX 2060 posts 65,846 while the T400 manages 16,263, a -75.3% delta. That translates to the RTX 2060 being about 4.05 times faster in Vulkan compute. These are not marginal differences; they are fundamental performance tiers.

Looking at the average benchmark scores across all listed tests, the T400’s average is 16,792, while the RTX 2060’s average is 15,290. This is counterintuitive given the head-to-head results, but it reflects the different test suites available. The T400 only has two Geekbench entries, both in the 16-17k range, while the RTX 2060 includes PassMark tests (DirectX 9/10/11/12, G2D, G3D, GPU compute) and a 3DMark Steel Nomad DX12 score of 1,242. The RTX 2060’s PassMark G3D score of 14,111 and GPU compute score of 5,488 pull its average down relative to its Geekbench peaks. In the shared tests, however, the RTX 2060 wins both with no contest.

The percentile rankings reinforce the gap. The T400 sits at the 60th percentile of all GPUs, while the RTX 2060 is at the 58th percentile. This seems odd at first, but percentiles are based on the entire benchmark database, not just the head-to-head tests. The T400’s two strong Geekbench scores place it slightly higher than the RTX 2060’s mixed suite of older DirectX and compute tests. Still, for any modern compute or graphics workload that uses OpenCL or Vulkan, the RTX 2060 is decisively ahead—by 73-75% in relative terms, which is a massive gulf.

Where Each One Wins

The RTX 2060 wins outright in every head-to-head benchmark listed, so its advantages are clear. In Geekbench OpenCL, it achieves a score nearly four times the T400’s; in Geekbench Vulkan, it is over four times higher. These results indicate the RTX 2060 is suited for compute-heavy tasks like rendering, simulation, and machine learning inference that leverage OpenCL or Vulkan. Its 6 GB memory, 192-bit bus, and 336 GB/s bandwidth (versus the T400’s 64-bit bus and 80 GB/s) also support larger datasets and higher throughput in memory-bound workloads, though those specs are not directly benchmarked in the head-to-head data.

The T400, despite losing both shared tests, has its own strengths. Its 30 W TDP and single-slot design mean it can fit into low-power or space-constrained systems where the RTX 2060’s 160 W TDP, dual-slot footprint, and 1x 8-pin power connector would be impractical. The T400 also requires a 200 W suggested PSU versus the RTX 2060’s 450 W, making it viable for office PCs or embedded systems. In the absence of direct benchmarks for those scenarios, the data shows the T400’s niche is not raw performance but efficiency and compatibility. Its average benchmark score of 16,792 actually exceeds the RTX 2060’s 15,290, so in the limited set of tests available, the T400 is not uniformly slower—it just loses in the two tests where they overlap.

The RTX 2060 also has more specialized hardware: 30 RT cores and 240 tensor cores, which the T400 lacks entirely. These enable ray tracing and AI-accelerated features, respectively, though no benchmark in the FACT PACK directly measures those capabilities. The T400 compensates with a higher transistor density (23.5M/mm² vs 24.3M/mm² for the RTX 2060, actually slightly lower) and a smaller die (200 mm² vs 445 mm²), but that is a physical attribute, not a performance one.

Architecture Differences

Both cards use the Turing architecture and are fabricated by TSMC on a 12 nm process, but the underlying chips are different. The T400 uses TU117, a small chip with 4,700 million transistors on a 200 mm² die. The RTX 2060 uses TU106, with 10,800 million transistors on a 445 mm² die. The RTX 2060’s die is over twice the size, and its transistor count is 2.3 times higher. Transistor density is similar (23.5M/mm² vs 24.3M/mm²), indicating the process node is used comparably, but the RTX 2060 simply has far more silicon to work with.

The execution resources differ by an order of magnitude. The T400 has 384 shading units, 24 texture mapping units (TMUs), and 16 ROPs. The RTX 2060 has 1,920 shading units (5 times more), 120 TMUs (5 times more), and 48 ROPs (3 times more). This explains the massive FP32 throughput gap: the T400 delivers 1,094.4 GFLOPS, while the RTX 2060 delivers 6,451 GFLOPS (6,451 TFLOPS in the pack, but the decimal is clear). Pixel rate is 22.80 GPixel/s for the T400 versus 80.64 GPixel/s for the RTX 2060, and texture rate is 34.20 GTexel/s versus 201.6 GTexel/s.

Memory is another major divider. The T400 has 4 GB of GDDR6 on a 64-bit bus, yielding 80 GB/s bandwidth. The RTX 2060 has 6 GB on a 192-bit bus, yielding 336 GB/s—4.2 times the bandwidth. Clock speeds also favor the RTX 2060: base 1,365 MHz vs 420 MHz, boost 1,680 MHz vs 1,425 MHz. Memory clock is 1,750 MHz (14 Gbps effective) for the RTX 2060 versus 1,250 MHz (10 Gbps effective) for the T400.

The RTX 2060 also has RT cores (30) and tensor cores (240), which are absent from the T400. This makes the RTX 2060 capable of hardware-accelerated ray tracing and tensor-based AI workloads, while the T400 relies purely on standard shader compute. API support differs too: the T400 supports DirectX 12 (12_1), while the RTX 2060 supports DirectX 12 Ultimate (12_2), which includes additional features like variable rate shading and mesh shaders. Both support OpenGL 4.6 and Vulkan 1.4.

FAQ

Q: Which GPU has a higher average benchmark score?

A: The NVIDIA T400 4 GB has an average benchmark score of 16,792, while the NVIDIA GeForce RTX 2060 averages 15,290. This is based on different test suites, so it does not reflect the head-to-head results.

Q: What is the performance difference in Geekbench Vulkan?

A: The RTX 2060 scores 65,846 in Geekbench Vulkan, compared to the T400’s 16,263. The RTX 2060 is 75.3% faster, meaning it achieves roughly four times the score.

Q: Does the T400 support ray tracing?

A: No. The T400 has no RT cores, while the RTX 2060 has 30 RT cores. The T400 also lacks tensor cores, which the RTX 2060 has 240 of.

Q: What are the power requirements for each card?

A: The T400 has a 30 W TDP and no power connectors, with a suggested PSU of 200 W. The RTX 2060 has a 160 W TDP, requires one 8-pin power connector, and needs a 450 W suggested PSU.

Q: How do memory bandwidths compare?

A: The T400 has 80 GB/s bandwidth from 4 GB GDDR6 on a 64-bit bus. The RTX 2060 has 336 GB/s from 6 GB GDDR6 on a 192-bit bus, which is 4.2 times higher.

Q: Which card has a higher pixel fill rate?

A: The RTX 2060 has a pixel rate of 80.64 GPixel/s, while the T400 has 22.80 GPixel/s. The RTX 2060 is roughly 3.5 times faster in this metric.

The Verdict

The data is unambiguous for raw performance: the NVIDIA GeForce RTX 2060 wins both head-to-head benchmarks by margins of 73-75%, and its compute resources (shading units, TMUs, ROPs, memory bandwidth) are all multiples of the T400’s. Anyone needing OpenCL or Vulkan compute throughput should choose the RTX 2060 without hesitation. Its 6 GB memory and 336 GB/s bandwidth also make it more suitable for larger workloads, and the presence of RT and tensor cores adds capabilities the T400 simply does not have.

The T400’s case rests on efficiency and form factor. It draws 30 W versus 160 W, fits in a single slot, requires no power connectors, and can run on a 200 W PSU. For a workstation that needs basic 3D acceleration or display output in a low-power environment, the T400 is the only sensible option between these two. Its average benchmark score of 16,792 also exceeds the RTX 2060’s 15,290, which suggests that in certain legacy or 2D-oriented tests, the T400 holds its own. But those tests are not in the head-to-head set, so they do not affect the comparison.

For a user who prioritizes compute performance, gaming, or ray tracing, the RTX 2060 is the clear pick. For a user who needs a low-profile, low-power card for basic workstation tasks, the T400 is the better fit. There is no middle ground: the benchmark delta is too large to ignore, and the power difference is too large to bridge.
