AMD Radeon Pro 460 vs AMD Radeon R9 370X Comparison

Head-to-Head Benchmarks

The recorded benchmark data reveals a clear split between these two AMD graphics processors, with each taking decisive victories in different API environments. The AMD Radeon Pro 460 wins two of the three head-to-head comparisons, while the AMD Radeon R9 370X takes one, and the margins tell a compelling story about where each card excels.

In the Geekbench Metal test, the AMD Radeon Pro 460 posts a score of 20426 against the AMD Radeon R9 370X's 12676. That is a 61.1% advantage for the Pro 460, a substantial gap that reflects the newer architecture's strength in Apple's Metal API. This result is particularly notable because Metal is the primary graphics API for macOS environments, and the Pro 460's generation was designed specifically for Mac systems.

The Geekbench OpenCL test flips the script entirely. Here, the AMD Radeon R9 370X scores 25893, while the AMD Radeon Pro 460 manages only 15284. The R9 370X leads by 41% in this compute-oriented workload. OpenCL is a general-purpose compute API, and the older card's higher raw compute resources, including more shading units and a wider memory bus, give it a decisive edge in this test.

Vulkan results once again favor the AMD Radeon Pro 460, and this is the largest margin of any comparison. The Pro 460 scores 16816, while the R9 370X trails at 9018. That works out to an 86.5% difference in favor of the newer card. The R9 370X supports Vulkan 1.2.170, while the Pro 460 supports Vulkan 1.3, and the newer specification along with the architectural improvements clearly translates into superior Vulkan performance.

Looking at the aggregate data, the AMD Radeon Pro 460's average benchmark score is 17509, placing it at the 61st percentile of all GPUs in the database. The AMD Radeon R9 370X averages 15862, sitting at the 58th percentile. The Pro 460's closest rivals include the NVIDIA Tesla K40c (17468, 0.2% behind), the AMD Radeon Pro 560 (17551, 0.2% ahead), and the AMD Radeon 780M (17588, 0.5% ahead). The R9 370X sits near the AMD Radeon RX 7700 (15852, 0.1% behind) and the AMD Radeon RX 9060 (16014, 1% ahead).

Architecture Differences

The two cards represent different generations of AMD's Graphics Core Next architecture. The AMD Radeon Pro 460 uses GCN 4.0 with the Baffin chip, while the AMD Radeon R9 370X uses GCN 1.0 with the Trinidad chip. This architectural gap spans multiple iterations and explains many of the performance differences observed in the benchmarks.

Manufacturing processes differ substantially. The Pro 460 is built on a 14 nm process at GlobalFoundries, while the R9 370X uses a 28 nm process at TSMC. The newer process allows the Pro 460 to pack 3,000 million transistors into a 123 mm² die, resulting in a transistor density of 24.4M per mm². The R9 370X, despite having fewer transistors at 2,800 million, requires a much larger 212 mm² die, giving it a density of just 13.2M per mm². This density difference is a direct consequence of the process node advancement.

Core configuration tells a nuanced story. The R9 370X has more shading units (1280 versus 1024), more texture mapping units (80 versus 64), and double the render output units (32 versus 16). Despite this hardware advantage on paper, the newer architecture of the Pro 460 compensates in several benchmark scenarios, particularly in Metal and Vulkan where API optimization matters more.

Clock speeds favor the R9 370X in terms of raw frequency. Its base clock is 980 MHz with a boost of 1030 MHz, while the Pro 460 runs at 850 MHz base and 907 MHz boost. Memory clocks also differ, with the R9 370X running at 1400 MHz (5.6 Gbps effective) versus 1270 MHz (5.1 Gbps effective) for the Pro 460.

Memory configuration is another major differentiator. The Pro 460 has 4 GB of GDDR5 on a 128-bit bus, yielding 81.28 GB/s of bandwidth. The R9 370X has 2 GB of GDDR5 on a 256-bit bus, providing 179.2 GB/s of bandwidth. The wider bus gives the older card more than double the memory bandwidth, which contributes to its OpenCL advantage.

Power characteristics show a stark contrast. The Pro 460 draws only 35 W TDP and requires no power connectors, fitting as an integrated graphics processor (IGP) solution. The R9 370X demands 180 W TDP, needs two 6-pin power connectors, and a suggested 450 W power supply. The R9 370X is also a dual-slot card at 221 mm in length, while the Pro 460's dimensions are portable-device dependent.

API support differs in important ways. The Pro 460 supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3. The R9 370X supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The newer DirectX feature level and Vulkan version on the Pro 460 explain some of its benchmark superiority in modern APIs.
