AMD Radeon Pro 5700 XT vs NVIDIA T400 4 GB Comparison

Head-to-Head Benchmarks

The database contains two direct benchmark comparisons between the AMD Radeon Pro 5700 XT and the NVIDIA T400 4 GB, and both are decisive victories for the AMD part. In Geekbench OpenCL, the Radeon Pro 5700 XT scores 59,467 against the T400’s 17,320, a margin of 243.3%. That is not a marginal lead; it is a performance gap of roughly three and a half times, meaning the AMD card completes compute workloads in a fraction of the time the NVIDIA card requires.

The Vulkan results tell a similar story. The Radeon Pro 5700 XT posts 56,593 in Geekbench Vulkan, while the T400 manages 16,263. The delta here is 248%, even slightly larger than the OpenCL gap. Across both recorded head-to-head tests, the AMD card wins 2 and the NVIDIA card wins 0. There is no benchmark in the shared set where the T400 comes out ahead, and the smallest margin of victory for AMD is still over 243%.

Context from the broader database reinforces these numbers. The Radeon Pro 5700 XT sits at the 63rd percentile of all GPUs, with an average benchmark score of 18,685. Its nearest rivals include the NVIDIA GeForce RTX 2070, which averages 18,789 and trails by 0.6%, and the NVIDIA Tesla K80 at 18,866, which leads by 1%. The T400, by contrast, sits at the 60th percentile with an average score of 16,792. Its nearest rival, the AMD Radeon RX 7600S, scores 16,696 and trails by 0.6%, while the NVIDIA GeForce GTX 690 leads it by 1.4%.

What stands out here is that the percentile gap between the two cards is small, just 63 versus 60, yet the head-to-head deltas are enormous. This is because the average benchmark score includes tests that the T400 simply does not have recorded data for. When both cards run the same compute-oriented workloads, the Radeon Pro 5700 XT’s advantage becomes stark. The average scores are pulled together by different test sets, but the direct comparisons leave no ambiguity about relative compute performance.

Where Each One Wins

The AMD Radeon Pro 5700 XT wins in every category where the two cards have overlapping benchmark data. In OpenCL compute, it delivers 59,467 points, which is 243.3% ahead of the T400. This matters for general-purpose GPU computing, OpenCL acceleration in productivity applications, and any workload that leverages the compute shaders of the card. In Vulkan, the AMD card scores 56,593, a 248% lead, indicating strong performance in modern graphics APIs and cross-platform compute workloads.

The NVIDIA T400 4 GB has no recorded wins in the shared benchmark set. Its strongest showing is in Geekbench OpenCL at 17,320, but that is still far behind the AMD card’s OpenCL result. The T400’s individual benchmark scores, 17,320 in OpenCL and 16,263 in Vulkan, are consistent with each other, but they do not approach the AMD card’s output.

For use-case segmentation, the data points toward the Radeon Pro 5700 XT as the choice for compute-heavy tasks where raw throughput matters. Its FP32 performance of 7.675 TFLOPS and texture rate of 239.8 GTexel/s are the kind of specifications that support demanding rendering and simulation work. The T400, with 1,094.4 GFLOPS FP32 and a 34.20 GTexel/s texture rate, is better suited to lightweight tasks, though the benchmark data does not show it winning any recorded test.

The T400 does have advantages in physical attributes. It is a single-slot card with a 30 W TDP, while the Radeon Pro 5700 XT is listed as IGP (integrated graphics processor) with a 130 W TDP. For compact systems or low-power environments, the T400’s efficiency profile is preferable. However, in pure benchmark performance, the AMD card dominates every measured category.

Architecture Differences

The two GPUs come from different architectural generations and foundry processes. The AMD Radeon Pro 5700 XT uses the Navi 10 chip built on RDNA 1.0 architecture, manufactured on a 7 nm process at TSMC. It contains 10,300 million transistors on a 251 mm² die, yielding a transistor density of 41.0M per mm². The NVIDIA T400 uses the TU117 chip based on Turing architecture, also from TSMC but on a 12 nm process. It packs 4,700 million transistors on a 200 mm² die, with a transistor density of 23.5M per mm².

These process differences are significant. The 7 nm node allows AMD to fit more than twice as many transistors into a die that is only 25% larger by area. The transistor density advantage, 41.0M per mm² versus 23.5M per mm², reflects the newer manufacturing technology. This density advantage translates directly into compute resources: the Radeon Pro 5700 XT has 2,560 shading units, 160 texture mapping units, and 64 raster output units. The T400 has 384 shading units, 24 TMUs, and 16 ROPs.

Memory architecture also differs sharply. The AMD card has 16 GB of GDDR6 memory on a 256-bit bus, delivering 384.0 GB/s of bandwidth. The T400 has 4 GB of GDDR6 on a 64-bit bus, yielding 80.00 GB/s. The AMD card has a 4.8x bandwidth advantage, which is consistent with its much higher compute throughput.

Clock behavior is another differentiator. The Radeon Pro 5700 XT has a base clock of 1243 MHz and a boost clock of 1499 MHz, with memory running at 1500 MHz (12 Gbps effective). The T400 has a base clock of just 420 MHz, boosting to 1425 MHz, with memory at 1250 MHz (10 Gbps effective). The AMD card’s base clock is nearly three times higher than the T400’s, though the boost clocks are closer.

Neither card has dedicated ray tracing cores or tensor cores. Both support DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The Radeon Pro 5700 XT uses a PCIe 4.0 x16 interface, while the T400 uses PCIe 3.0 x16, giving the AMD card double the bandwidth to the host system.

Specification Differences

The specification sheet separates these cards across nearly every major category. The Radeon Pro 5700 XT has 16 GB of GDDR6 memory, while the T400 has 4 GB. Memory bus width is 256-bit versus 64-bit, and bandwidth is 384.0 GB/s versus 80.00 GB/s. Shading units are 2,560 versus 384, TMUs are 160 versus 24, and ROPs are 64 versus 16.

Pixel rate and texture rate follow the same pattern. The AMD card achieves 95.94 GPixel/s and 239.8 GTexel/s, while the T400 achieves 22.80 GPixel/s and 34.20 GTexel/s. FP32 compute is 7.675 TFLOPS versus 1,094.4 GFLOPS. FP16 performance is 15.35 TFLOPS (2:1) on the AMD card versus 2.189 TFLOPS (2:1) on the T400.

Power characteristics could not be more different. The Radeon Pro 5700 XT has a 130 W TDP and requires a 300 W suggested PSU, while the T400 draws just 30 W with a 200 W suggested PSU. The AMD card is listed as IGP with no power connectors and no display outputs, meaning it is designed for integration into Apple Mac systems. The T400 is a single-slot card with no power connectors and features 3x mini-DisplayPort 1.4a outputs, making it a functional standalone graphics card.

The bus interface also differs: PCIe 4.0 x16 on the AMD side versus PCIe 3.0 x16 on the NVIDIA side. Production status is end-of-life for both. Release dates are 2020-08-03 for the AMD card and 2021-05-05 for the T400. The T400 has a predecessor, Quadro Volta, and a successor, Workstation Ampere, while the AMD card lists neither.
