Architecture Differences

The NVIDIA Tesla M4 is built on the GM206 chip using Maxwell 2.0 architecture, manufactured on a 28 nm process at TSMC. It packs 2,940 million transistors on a 228 mm² die, giving a transistor density of 12.9M per mm². The chip features 1,024 shading units, 64 texture mapping units, and 32 raster operation pipelines.

The AMD Radeon Pro 560X uses the Polaris 21 chip with GCN 4.0 architecture, produced on a 14 nm process at GlobalFoundries. It contains 3,000 million transistors on a much smaller 123 mm² die, resulting in a higher density of 24.4M per mm². The Radeon Pro 560X also has 1,024 shading units and 64 TMUs, but only 16 ROPs, half the count of the Tesla M4.

Clock behavior differs significantly. The Tesla M4 has defined base and boost clocks of 872 MHz and 1,072 MHz respectively. The Radeon Pro 560X has no base or boost clocks listed in the database, only a memory clock of 1,470 MHz (5.9 Gbps effective). This suggests the AMD part relies on dynamic boosting in the Mac systems where it was deployed.

Memory architecture is similar on paper: both use 4 GB of GDDR5 on a 128-bit bus. However, the Radeon Pro 560X has a higher memory bandwidth at 94.08 GB/s compared to 88.00 GB/s for the Tesla M4, thanks to its faster memory clock.

The Tesla M4 is a single-slot PCIe 3.0 x16 card with no display outputs, designed for compute workloads in servers. The Radeon Pro 560X is an integrated GPU (IGP) with a PCIe 3.0 x8 interface, has no power connectors, and its display outputs are portable device dependent, meaning it was soldered into laptops. The Tesla M4 has a suggested PSU rating of 250 W, while the Radeon Pro 560X does not list one.

The Tesla M4 supports DirectX 12_1, OpenGL 4.6, and Vulkan 1.4. The Radeon Pro 560X supports DirectX 12_0, OpenGL 4.6, and Vulkan 1.3. The AMD part also lists FP16 compute at 2.056 TFLOPS (1:1 ratio), while the NVIDIA part does not provide an FP16 figure.

The Verdict

The data shows two different design philosophies. The NVIDIA Tesla M4 is a dedicated compute accelerator with a higher pixel rate (34.30 GPixel/s vs 16.06 GPixel/s) and higher texture rate (68.61 GTexel/s vs 64.26 GTexel/s). It also delivers more raw FP32 compute at 2.195 TFLOPS versus 2.056 TFLOPS for the Radeon Pro 560X.

For OpenCL workloads, the Tesla M4 is the clear choice. Its 16,932 score beats the Radeon Pro 560X's 9,663 by 75.2%. This is not a marginal difference; it is a dominant win. The Tesla M4 also ranks higher in the overall GPU percentile at 60 versus 57.

However, the Radeon Pro 560X has advantages that matter in specific contexts. It offers higher memory bandwidth (94.08 GB/s vs 88.00 GB/s), supports FP16 compute at a 1:1 ratio, and is designed for portable Mac systems where integrated graphics are required. Its Metal score of 18,763 and Vulkan score of 16,819 show strong API-specific performance, though the Tesla M4 has no recorded Metal or Vulkan results.

Pick the NVIDIA Tesla M4 if you need maximum OpenCL throughput, higher pixel fill, and lower power draw in a server or workstation compute role. Pick the AMD Radeon Pro 560X if you are working within Apple's portable ecosystem, need FP16 support, or require the higher memory bandwidth for bandwidth-sensitive tasks. The Radeon Pro 560X also offers more API coverage in the benchmark database with three recorded tests versus one for the Tesla M4.

Head-to-Head Benchmarks

The database records one direct comparison between these two GPUs: Geekbench OpenCL. The NVIDIA Tesla M4 scores 16,932 against 9,663 for the AMD Radeon Pro 560X. This translates to a 75.2% advantage for the Tesla M4, a substantial gap that indicates the NVIDIA part is far better suited for OpenCL compute tasks.

Context from nearest rivals reinforces this picture. The Tesla M4's nearest rivals include the AMD Radeon HD 7970M (17,019, -0.5% delta), the NVIDIA GeForce GTX 690 (17,037, -0.6% delta), the NVIDIA T400 4 GB (16,792, +0.8% delta), and the AMD Radeon RX 7600 XT (17,083, -0.9% delta). All of these are within roughly one percentage point of the Tesla M4, meaning the Tesla M4 sits in a tightly competitive cluster of GPUs from multiple generations.

The Radeon Pro 560X's nearest rivals are the NVIDIA GeForce GTX 660 Ti (15,063, +0.1% delta), the AMD Radeon RX 7600 (15,171, -0.6% delta), the NVIDIA GeForce RTX 3050 OEM (15,199, -0.8% delta), and the AMD Radeon 680M (15,270, -1.2% delta). These rivals are also tightly clustered, but at a lower performance tier. The average of these rivals sits around 15,170, compared to the Tesla M4's rival cluster average around 16,980.

This means the Tesla M4's OpenCL performance places it roughly 12% above the Radeon Pro 560X's nearest competitive set. The Radeon Pro 560X, despite having a higher memory bandwidth and newer process node, cannot overcome the Tesla M4's architectural advantages in raw compute throughput.

The Radeon Pro 560X does have recorded results in Metal (18,763) and Vulkan (16,819), but the Tesla M4 has no corresponding entries in those tests. Without direct comparisons in those APIs, the only head-to-head data available strongly favors the NVIDIA part.

Where Each One Wins

The NVIDIA Tesla M4 wins in OpenCL compute, which is the only directly comparable benchmark. It also wins on paper in pixel rate (34.30 vs 16.06 GPixel/s), texture rate (68.61 vs 64.26 GTexel/s), and FP32 throughput (2.195 vs 2.056 TFLOPS). Its lower TDP of 50 W versus 75 W makes it the more power-efficient option for dense compute deployments.

The Tesla M4's nearest rival data shows it performs at the level of much larger GPUs like the GeForce GTX 690 and the Radeon RX 7600 XT. This suggests that for compute tasks in a server context, the Tesla M4 punches above its 50 W envelope.

The AMD Radeon Pro 560X wins in memory bandwidth, offering 94.08 GB/s compared to 88.00 GB/s. It also supports FP16 compute at a 1:1 ratio, a feature the Tesla M4 does not list. Its Metal score of 18,763 is the highest single benchmark score in this entire comparison, though it cannot be directly compared to the Tesla M4 due to missing data.

The Radeon Pro 560X is the only one of the two with display outputs (portable device dependent) and no power connectors, making it suitable for laptop integration. The Tesla M4 has no outputs and requires an external PSU rating of 250 W, indicating it belongs in a server chassis.

For users working in Apple's Metal ecosystem, the Radeon Pro 560X offers a recorded score of 18,763, which is strong. For Vulkan workloads, its 16,819 score is also respectable. The Tesla M4 has no recorded results in either API, so any decision between these two for non-OpenCL workloads must rely on the Radeon Pro 560X's data alone.

In practical terms: the Tesla M4 is the compute specialist, the Radeon Pro 560X is the mobile all-rounder. The Tesla M4 wins where OpenCL is the workload and power efficiency matters. The Radeon Pro 560X wins where portability, FP16 support, and memory bandwidth take priority. Given the 75.2% OpenCL gap, the Tesla M4 is the stronger pure performer, but the Radeon Pro 560X's broader feature set and API coverage make it the more flexible choice for Mac-based systems.
