AMD Radeon RX 560X vs NVIDIA T400 4 GB Comparison

Head-to-Head Benchmarks

The recorded database results for these two cards show a clear split depending on the API used. In the Geekbench OpenCL test, the NVIDIA T400 4 GB scores 17320, while the AMD Radeon RX 560X scores 17020. That puts the T400 ahead by 1.7%. This is a narrow margin, well within the range of run-to-run variance, but the recorded data still awards the win to NVIDIA. In the Geekbench Vulkan test, the situation reverses dramatically. The RX 560X scores 20231, which is 24.4% higher than the T400's 16263. That is a substantial gap, not a marginal one. The RX 560X is the clear winner in Vulkan workloads.

Looking at the broader averages, the RX 560X has an average benchmark score of 18626 across the two recorded tests. The T400 sits lower at 16792. That gives the AMD card an overall average advantage of roughly 1,834 points, or about 10.9% higher than the T400's average. When placed against the nearest rivals in the database, the RX 560X's average score puts it 0.3% behind the AMD Radeon Pro 5700 XT, 0.5% ahead of the AMD FirePro D500, 0.9% behind the NVIDIA GeForce RTX 2070, and 1.3% behind the NVIDIA Tesla K80. The T400, by comparison, sits 0.6% ahead of the AMD Radeon RX 7600S, 0.8% behind the NVIDIA Tesla M4, 1.3% behind the AMD Radeon HD 7970M, and 1.4% behind the NVIDIA GeForce GTX 690. The RX 560X's percentile rank among all GPUs is 62, while the T400 sits at 60. These are close overall positions, but the Vulkan result is the decisive differentiator in raw performance.

The OpenCL numbers deserve a closer look. The T400's 17320 versus the RX 560X's 17020 is a difference of only 300 points. In relative terms, that is 1.7%, which is a small enough gap that other factors like driver state or thermal conditions could flip the result. The database records it as a win for the T400, and the analysis should respect that, but the magnitude is not impressive. Meanwhile, the Vulkan result is the opposite. A 24.4% lead is a dominant margin. The RX 560X's 20231 in Vulkan is not just higher than the T400's 16263; it is also higher than the RX 560X's own OpenCL score by 3,211 points, indicating that the AMD card scales better under Vulkan. The T400, by contrast, scores lower in Vulkan than in OpenCL, dropping from 17320 to 16263. That is a 6.1% regression for NVIDIA when moving from OpenCL to Vulkan.

The delta percentages against nearest rivals reinforce the picture. For the RX 560X, the closest rival is the AMD Radeon Pro 5700 XT at a 0.3% gap, which means the RX 560X is essentially in the same performance tier as that workstation card. For the T400, the closest rival is the AMD Radeon RX 7600S at 0.6% ahead. Both cards are clustered with their respective peer groups, but the RX 560X's higher average score and higher percentile rank indicate a slight overall edge in the database's aggregated measurements.

Where Each One Wins

The AMD Radeon RX 560X wins decisively in Vulkan compute workloads. The recorded Vulkan score of 20231 is 24.4% above the T400's 16263. This is the single largest head-to-head margin in the database for these two cards. Any application or workload that leverages Vulkan for general-purpose compute will favor the RX 560X. The architecture behind this is GCN 4.0 on a 14 nm process with 1,024 shading units, 64 texture mapping units, and 16 ROPs. The FP32 throughput is 2.611 TFLOPS, and FP16 is identical at 2.611 TFLOPS with a 1:1 ratio. That means the RX 560X does not have a separate fast FP16 path; it treats FP16 and FP32 equally. For Vulkan workloads that rely on raw FP32 throughput, the RX 560X has a clear advantage on paper, and the benchmark confirms it.

The NVIDIA T400 4 GB wins in OpenCL. Its score of 17320 beats the RX 560X's 17020 by 1.7%. The T400 is built on the Turing architecture, TU117 chip, on a 12 nm process at TSMC. It has 384 shading units, 24 TMUs, and 16 ROPs. Its FP32 throughput is 1,094.4 GFLOPS, which is less than half of the RX 560X's 2.611 TFLOPS. Yet in OpenCL, it still manages to edge out the AMD card. This suggests that the T400's OpenCL implementation is more efficient, or that the workload in the OpenCL test is not purely bound by raw FP32 rate. The T400's memory configuration is also notable: 4 GB of GDDR6 on a 64 bit bus delivers 80.00 GB/s of bandwidth, compared to the RX 560X's 4 GB of GDDR5 on a 128 bit bus delivering 112.0 GB/s. The RX 560X has more bandwidth, yet loses OpenCL. That points to software or scheduling differences rather than memory capacity.

In terms of pixel and texture rates, the T400 has a higher pixel rate at 22.80 GPixel/s versus the RX 560X's 20.40 GPixel/s, but the RX 560X has a much higher texture rate at 81.60 GTexel/s versus the T400's 34.20 GTexel/s. For texture-heavy workloads, the RX 560X should be faster. For pixel-fill-limited scenarios, the T400 holds a slight edge. The database does not include separate texture or pixel benchmarks for these cards, so those rates are architectural characteristics, not measured wins. The measured wins are strictly the two Geekbench tests.

The T400 also has a lower power draw at 30 W versus the RX 560X's 75 W, and it is a single-slot card with no power connectors, while the RX 560X is dual-slot and also has no power connectors. The T400 uses a PCIe 3.0 x16 interface, while the RX 560X uses PCIe 3.0 x8. For bandwidth-sensitive workloads that are not captured in the two recorded benchmarks, the T400's wider bus interface could matter, but the recorded data does not show a PCIe-specific test.

The Verdict

Based strictly on the recorded data, the AMD Radeon RX 560X is the better overall performer. Its average benchmark score of 18626 exceeds the T400's 16792 by 1,834 points, and its percentile rank of 62 is two points higher than the T400's 60. The decisive factor is the Vulkan result, where the RX 560X leads by 24.4%. If the target workload uses Vulkan, the RX 560X is the correct choice. The T400's only win is the OpenCL test, and that win is narrow at 1.7%. The T400 does have the advantage of a lower 30 W TDP, a single-slot form factor, and a PCIe 3.0 x16 interface, which are meaningful for compact or power-constrained systems, but those are not benchmark scores. The performance data favors the RX 560X.

For users who prioritize OpenCL compute, the T400 is competitive but not dominant. Its 17320 OpenCL score is only 1.7% above the RX 560X, so the choice between the two in an OpenCL-only environment would be close. The T400 also supports DirectX 12 (12_1) and Vulkan 1.4, while the RX 560X supports DirectX 12 (12_0) and Vulkan 1.3. The T400 has a newer API feature level for DirectX and a newer Vulkan version. That could matter for compatibility with newer software, even if the raw Vulkan performance is lower. The RX 560X, however, has double the texture rate, higher memory bandwidth, and more than double the FP32 throughput. Its FP16 performance is also equal to FP32, which is unusual and could be useful for workloads that historically used FP16 without a dedicated fast path.

The verdict from the database is straightforward: the RX 560X wins on measured performance, especially in Vulkan. The T400 wins on efficiency and form factor, plus a narrow OpenCL margin. Anyone selecting between these two should look at the API in use. Vulkan-based applications point to AMD. OpenCL-only environments are a toss-up, with the T400 holding a slight edge. For general compute, the RX 560X's higher average score and higher percentile make it the stronger card.

Architecture Differences

The two cards come from different architectures, process nodes, and foundries. The AMD Radeon RX 560X uses the Polaris 21 chip based on GCN 4.0 architecture, fabricated on a 14 nm process at GlobalFoundries. It contains 3,000 million transistors on a die size of 123 mm², giving a transistor density of 24.4 million per mm². The NVIDIA T400 4 GB uses the TU117 chip based on Turing architecture, fabricated on a 12 nm process at TSMC. It contains 4,700 million transistors on a die size of 200 mm², giving a transistor density of 23.5 million per mm². The T400 has more transistors and a larger die, but a slightly lower transistor density.

The compute configurations differ substantially. The RX 560X has 1,024 shading units, 64 TMUs, and 16 ROPs. The T400 has 384 shading units, 24 TMUs, and 16 ROPs. The RX 560X has nearly three times the shading units and more than double the TMUs, but the same number of ROPs. The RX 560X's FP32 throughput is 2.611 TFLOPS, and its FP16 throughput is identical at 2.611 TFLOPS with a 1:1 ratio. The T400's FP32 throughput is 1,094.4 GFLOPS, but its FP16 throughput is 2.189 TFLOPS with a 2:1 ratio. This means the T400 can execute FP16 at twice the rate of FP32, while the RX 560X treats both equally.

Clock speeds also differ. The RX 560X has a base clock of 1175 MHz and a boost clock of 1275 MHz. The T400 has a much lower base clock of 420 MHz but a higher boost clock of 1425 MHz. The memory clocks are 1750 MHz for the RX 560X, which translates to 7 Gbps effective on GDDR5, and 1250 MHz for the T400, which translates to 10 Gbps effective on GDDR6. Despite the higher effective memory speed, the T400's 64 bit bus limits its bandwidth to 80.00 GB/s, while the RX 560X's 128 bit bus provides 112.0 GB/s.

The memory types are different: GDDR5 for AMD and GDDR6 for NVIDIA. Both have 4 GB capacity. The bus widths are 128 bit and 64 bit, respectively. The pixel rates are 20.40 GPixel/s for the RX 560X and 22.80 GPixel/s for the T400. The texture rates are 81.60 GTexel/s for the RX 560X and 34.20 GTexel/s for the T400. The T400 has a higher pixel rate, while the RX 560X has a much higher texture rate.
