AMD Radeon Pro 5700 vs NVIDIA T400 4 GB Comparison

AMD Radeon Pro 5700 vs NVIDIA T400 4 GB: the data shows a decisive, one-sided contest. Across the two shared benchmark tests, the AMD Radeon Pro 5700 wins both, with margins exceeding 200%. The NVIDIA T400 4 GB, while a competent low-power workstation card, is outclassed in raw compute throughput by the older, larger AMD part.

Head-to-Head Benchmarks

The head-to-head data is limited to two Geekbench tests, but the results are unambiguous. In Geekbench OpenCL, the AMD Radeon Pro 5700 scores 52,787 against the NVIDIA T400 4 GB's 17,320. This represents a delta of 204.8%, meaning the AMD card delivers roughly three times the compute performance in this workload. The margin is even larger in Vulkan: the AMD scores 51,289 versus the NVIDIA's 16,263, a delta of 215.4%. Both tests show the same pattern—the Radeon Pro 5700 is not merely faster; it is in a different performance class entirely.

These deltas are not close calls. For context, the Radeon Pro 5700's nearest rivals in the overall benchmark database include the NVIDIA GeForce RTX 3060 Mobile (average score 18,159, delta 0.2%) and the NVIDIA GeForce RTX 2060 SUPER (18,093, delta 0.5%). The T400 4 GB's nearest rivals include the AMD Radeon RX 7600S (16,696, delta 0.6%) and NVIDIA Tesla M4 (16,932, delta -0.8%). The difference between the two cards' average benchmark scores is stark: 18,189 for the AMD versus 16,792 for the NVIDIA. That is a gap of roughly 1,400 points, but the head-to-head deltas show the real story: in compute-heavy synthetic loads, the AMD card is roughly 200% faster, not 8% faster.

The win count is 2–0 in favor of the AMD Radeon Pro 5700. There are no benchmark categories where the NVIDIA T400 4 GB pulls ahead, no hidden strength in a specific API. Both cards support DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4, so the API feature set is identical; the difference is purely in execution resources.

Architecture Differences

The underlying silicon explains the performance chasm. The AMD Radeon Pro 5700 uses the Navi 10 chip on TSMC's 7 nm process, packing 10,300 million transistors into a 251 mm² die. That works out to a transistor density of 41.0M per mm². The NVIDIA T400 4 GB uses the TU117 chip on TSMC's 12 nm process, with 4,700 million transistors on a 200 mm² die, for a density of 23.5M per mm². The AMD chip has more than double the transistor count, despite being only 51 mm² larger in die area.

The compute resources are likewise lopsided. The AMD Radeon Pro 5700 has 2,304 shading units, 144 texture mapping units, and 64 raster output pipelines. The NVIDIA T400 4 GB has 384 shading units, 24 TMUs, and 16 ROPs. That is a 6:1 ratio in shading units, a 6:1 ratio in TMUs, and a 4:1 ratio in ROPs. Peak pixel rate for the AMD is 86.40 GPixel/s versus 22.80 GPixel/s for the NVIDIA; texture rate is 194.4 GTexel/s versus 34.20 GTexel/s. FP32 compute is 6.221 TFLOPS for the AMD versus 1,094.4 GFLOPS for the NVIDIA. FP16 rates are 12.44 TFLOPS (2:1) and 2.189 TFLOPS (2:1) respectively. In every arithmetic category, the AMD card holds a 4x to 6x advantage.

Memory is another major divider. The AMD Radeon Pro 5700 has 8 GB of GDDR6 on a 256-bit bus, delivering 384.0 GB/s of bandwidth. The NVIDIA T400 4 GB has 4 GB of GDDR6 on a 64-bit bus, delivering 80.00 GB/s. The AMD card has twice the capacity and nearly five times the bandwidth. Clock speeds tell a more nuanced story: the AMD has a base clock of 1243 MHz and boost of 1350 MHz, while the NVIDIA has a much lower base of 420 MHz but a higher boost of 1425 MHz. The NVIDIA's boost clock is higher, but the massive difference in shader count makes clock speed irrelevant to the outcome.

Power and physical design diverge sharply. The AMD Radeon Pro 5700 is an integrated graphics processor (IGP) with no power connectors, a 130 W TDP, and a suggested PSU of 300 W. The NVIDIA T400 4 GB is a single-slot card with no power connectors, a 30 W TDP, and a suggested PSU of 200 W. The AMD card uses PCIe 4.0 x16, while the NVIDIA uses PCIe 3.0 x16. The NVIDIA has three mini-DisplayPort 1.4a outputs; the AMD has no display outputs at all. Both are end-of-life products, with the AMD released 2020-08-03 and the NVIDIA released 2021-05-05.

Where Each One Wins

The AMD Radeon Pro 5700 wins every compute-heavy scenario. Its 204.8% lead in OpenCL and 215.4% lead in Vulkan make it the clear choice for any workload that stresses raw FP32 or FP16 throughput, such as GPU compute, rendering, or scientific simulation. The 6.221 TFLOPS FP32 figure and 384.0 GB/s memory bandwidth support this: the card can feed its shaders at a rate the NVIDIA cannot approach. The 8 GB frame buffer also allows larger datasets to reside on-card, avoiding PCIe transfers.

The NVIDIA T400 4 GB's only advantages are in physical and power characteristics. It is a single-slot card with a 30 W TDP and a 200 W suggested PSU, compared to the AMD's 130 W TDP and 300 W suggested PSU. For a system with tight power or space constraints, the NVIDIA is the more accommodating option. Its 3x mini-DisplayPort 1.4a outputs also make it a functional display adapter, whereas the AMD Radeon Pro 5700 has no outputs, meaning it requires a separate GPU for any visual output. The NVIDIA's higher boost clock of 1425 MHz versus the AMD's 1350 MHz is a minor point, but it does not compensate for the 6:1 shader deficit.

In terms of benchmark percentiles, the AMD card sits at the 62nd percentile of all GPUs, with an average benchmark score of 18,189. The NVIDIA sits at the 60th percentile, with an average score of 16,792. The percentile gap is small—only two points—but the average score gap is real. The AMD's nearest rival is the Intel Arc A770M at 18,383 (delta -1.1%), meaning the AMD is slightly below that card. The NVIDIA's nearest rival above it is the AMD Radeon HD 7970M at 17,019 (delta -1.3%), a much older part.

The Verdict

The data is unambiguous: the AMD Radeon Pro 5700 is the superior compute performer by a wide margin. In the only two shared benchmarks, it leads by 204.8% and 215.4%, respectively. Its 2,304 shading units, 6.221 TFLOPS FP32, and 384.0 GB/s bandwidth make it a serious compute card, suitable for workloads where raw throughput matters. The NVIDIA T400 4 GB, with 384 shading units and 1,094.4 GFLOPS, is not competitive in this space.

However, the choice is not purely performance-based. The AMD Radeon Pro 5700 is an IGP with no display outputs, meaning it cannot be used as a primary graphics adapter. It requires a host GPU for display and is intended for compute-accelerated tasks in a Mac environment, given its generation label "Radeon Pro Mac". The NVIDIA T400 4 GB is a standalone card with three display outputs, a 30 W TDP, and a single-slot form factor, making it suitable for low-profile workstation builds where space and power are at a premium.

For a user who needs compute performance and already has a display solution, the AMD Radeon Pro 5700 is the statistically correct pick. For a user who needs a low-power, single-slot card with display outputs for basic workstation duties, the NVIDIA T400 4 GB is the only viable option in this comparison. The average benchmark scores (18,189 vs 16,792) reflect this: the AMD is roughly 8% faster on average, but the head-to-head tests show the real-world compute gap is far larger.
