AMD Radeon Pro 560X vs NVIDIA T400 Comparison

Head-to-Head Benchmarks

The database records two shared benchmark tests between the NVIDIA T400 and the AMD Radeon Pro 560X, and the results are strikingly split. In Geekbench OpenCL, the NVIDIA T400 delivers a score of 17,039 against the AMD Radeon Pro 560X's 9,663. That is a delta of 76.3% in favor of the T400, a massive margin that places the two cards in entirely different performance tiers for compute workloads. The T400's OpenCL result is not just a narrow win; it nearly doubles the AMD part's output in this specific test.

However, the Geekbench Vulkan result flips the narrative. Here, the AMD Radeon Pro 560X scores 16,819, while the NVIDIA T400 trails with 15,976. The delta is 5% in AMD's favor, a modest but clear advantage. This is curious: the same two GPUs, but the relative performance changes dramatically depending on the API. The data suggests the AMD card handles Vulkan workloads with noticeably better efficiency, while the NVIDIA card dominates in OpenCL. For a prospective buyer, this split means the choice hinges heavily on which software stack or application they intend to run.

Looking at the broader benchmark averages, the NVIDIA T400 posts an avgBenchmarkScore of 16,508, which places it at the 60th percentile among all GPUs in the database. The AMD Radeon Pro 560X, by contrast, has an avgBenchmarkScore of 15,082, sitting at the 57th percentile. The T400's average is roughly 9.5% higher, but the individual test results show that this overall advantage is entirely driven by the OpenCL score. In Vulkan, the AMD part is the winner, so the average masks a more nuanced picture.

The nearest rivals for the T400 include the NVIDIA GeForce RTX 5090 D V2 with an avgScore of 16,504 (a 0% delta), the AMD Radeon PRO W7500 at 16,415 (0.6% behind), and the NVIDIA RTX PRO 6000 Blackwell at 16,408 (0.6% behind). This clustering means the T400's average score is effectively tied with several far more expensive or powerful workstation cards, which reflects its efficiency in the recorded benchmarks. For the AMD Radeon Pro 560X, the nearest rivals are the NVIDIA GeForce GTX 660 Ti at 15,063 (0.1% behind), the AMD Radeon RX 7600 at 15,171 (0.6% ahead), and the NVIDIA GeForce RTX 3050 OEM at 15,199 (0.8% ahead). The AMD card's average sits in a tight pack with these older or lower-tier parts, indicating it is competitive in its segment but not exceptional.

Architecture Differences

The two GPUs come from different architectural generations and manufacturing processes. The NVIDIA T400 is built on the TU117 chip using the Turing architecture, fabricated on a 12 nm process at TSMC. It contains 4,700 million transistors on a 200 mm² die, giving a transistor density of 23.5M per mm². The AMD Radeon Pro 560X, in contrast, uses the Polaris 21 chip with GCN 4.0 architecture, built on a 14 nm process at GlobalFoundries. It packs 3,000 million transistors into a 123 mm² die, resulting in a slightly higher transistor density of 24.4M per mm².

The compute resources differ significantly. The NVIDIA T400 has 384 shading units, 24 texture mapping units (TMUs), and 16 raster operation units (ROPs). The AMD Radeon Pro 560X has 1,024 shading units, 64 TMUs, and 16 ROPs. Despite having fewer shading units, the T400 achieves a higher pixel rate of 22.80 GPixel/s versus the AMD's 16.06 GPixel/s, likely due to its higher boost clock. The T400's boost clock is 1425 MHz, while the AMD card's base and boost clocks are not listed in the database. The texture rate tells a different story: the AMD part posts 64.26 GTexel/s, nearly double the T400's 34.20 GTexel/s, reflecting its higher TMU count.

Memory architecture also diverges. The T400 uses 2 GB of GDDR6 with a 64-bit bus and a memory clock of 1250 MHz (10 Gbps effective), delivering 80.00 GB/s. The AMD part uses 4 GB of GDDR5 with a 128-bit bus and a memory clock of 1470 MHz (5.9 Gbps effective), delivering 94.08 GB/s. The AMD card has both more capacity and higher bandwidth, which may benefit certain workloads.

Feature support shows subtle differences. Both support DirectX 12, but the T400 supports version 12_1 while the AMD card supports 12_0. OpenGL is identical at 4.6. Vulkan support differs: the T400 lists Vulkan 1.4, while the AMD card lists Vulkan 1.3. The T400 also has a different display output configuration, featuring 3x mini-DisplayPort 1.4a, while the AMD card's display outputs are listed as "Portable Device Dependent," reflecting its intended use in laptops. The bus interface also differs: the T400 uses PCIe 3.0 x16, while the AMD card uses PCIe 3.0 x8.

The Verdict

The data paints a clear picture for different use cases. The NVIDIA T400 is the compute powerhouse in OpenCL, with a 76.3% lead over the AMD Radeon Pro 560X in that specific test. Its higher average benchmark score (16,508 vs 15,082) and superior percentile ranking (60th vs 57th) make it the stronger all-around performer in the database's recorded metrics. For applications that rely on OpenCL, the T400 is the unequivocal choice.

The AMD Radeon Pro 560X, however, has its own strengths. It wins in Vulkan by 5%, and it offers double the memory capacity (4 GB vs 2 GB) with higher bandwidth (94.08 GB/s vs 80.00 GB/s). The AMD card also has a significantly higher texture rate (64.26 GTexel/s vs 34.20 GTexel/s), which could benefit texture-heavy workloads. For users whose software leverages Vulkan or requires more memory, the AMD part holds a tangible advantage.

The choice ultimately depends on the software environment. If the primary workload is OpenCL-based, the NVIDIA T400 is the clear winner. If Vulkan performance or memory capacity is more critical, the AMD Radeon Pro 560X is the better fit. The data does not support a universal verdict; it supports a workload-specific one.
