AMD Radeon Pro 460 vs AMD Radeon RX 5500 XT Comparison

AMD Radeon Pro 460 vs AMD Radeon RX 5500 XT

The recorded data shows a decisive performance gap between the AMD Radeon Pro 460 and the AMD Radeon RX 5500 XT, with the latter winning every single head-to-head benchmark comparison. The RX 5500 XT, built on a newer architecture and process node, delivers substantially higher raw compute throughput, memory bandwidth, and pixel processing rates across the board, making it the clearly faster part in all measured workloads.

Where Each One Wins

The AMD Radeon Pro 460 does not win a single benchmark in the head-to-head comparison. The database contains three shared tests, and the RX 5500 XT claims victory in all of them. The Pro 460’s strongest showing is in the Geekbench Metal test, where it scores 20426 points, but even there the RX 5500 XT posts 54842 points, a 62.8 percent deficit for the older card. The Pro 460 is effectively a low-power mobile workstation GPU, designed for integrated use in portable systems with a 35 W TDP, whereas the RX 5500 XT is a dual-slot desktop card with a 130 W TDP and a dedicated 8-pin power connector.

The RX 5500 XT wins across compute and graphics workloads alike. Its Geekbench OpenCL score of 46965 is 67.5 percent higher than the Pro 460’s 15284, and its Geekbench Vulkan score of 44191 is 61.9 percent higher than the Pro 460’s 16816. The RX 5500 XT also holds a strong position in the wider database, with a PassMark G3D score of 9083 and a PassMark GPU Compute score of 4446, while the Pro 460 has no equivalent PassMark entries. The RX 5500 XT’s percentile ranking of 57 places it slightly below the Pro 460’s 61, but this reflects the broader distribution of all GPUs in the database rather than the direct comparison between these two parts.

Architecture Differences

The two GPUs come from different architectural generations. The Radeon Pro 460 uses the Baffin chip based on GCN 4.0, fabricated on a 14 nm process at GlobalFoundries. The Radeon RX 5500 XT uses the Navi 14 chip based on RDNA 1.0, fabricated on a 7 nm process at TSMC. The process shrink allows the Navi 14 die to pack 6400 million transistors into a 158 mm² die, resulting in a transistor density of 40.5M per mm², compared to the Baffin’s 3000 million transistors on a 123 mm² die at 24.4M per mm².

The architectural shift from GCN to RDNA brings significant changes to the execution pipeline. The RX 5500 XT has 1408 shading units, 88 texture mapping units, and 32 render output units, while the Pro 460 has 1024 shading units, 64 TMUs, and 16 ROPs. The RX 5500 XT also operates at much higher clocks, with a base of 1607 MHz, a game clock of 1717 MHz, and a boost of 1845 MHz, versus the Pro 460’s 850 MHz base and 907 MHz boost. The memory subsystem differs as well: the RX 5500 XT uses 4 GB of GDDR6 at 1750 MHz with 14 Gbps effective speed, delivering 224.0 GB/s of bandwidth, while the Pro 460 uses 4 GB of GDDR5 at 1270 MHz with 5.1 Gbps effective speed, delivering 81.28 GB/s.

The FP16 capabilities also diverge. The RX 5500 XT achieves 10.39 TFLOPS of FP16 performance at a 2:1 ratio relative to FP32, while the Pro 460 delivers 1.858 TFLOPS of FP16 at a 1:1 ratio. This makes the newer card substantially more capable for half-precision compute workloads. The API support also differs, with the RX 5500 XT supporting DirectX 12 (12_1) and Vulkan 1.4, while the Pro 460 supports DirectX 12 (12_0) and Vulkan 1.3. The RX 5500 XT also uses a PCIe 4.0 x8 interface compared to the Pro 460’s PCIe 3.0 x8.

Head-to-Head Benchmarks

The Geekbench Metal test shows the largest absolute gap in the shared benchmark set. The RX 5500 XT scores 54842, which is 62.8 percent ahead of the Pro 460’s 20426. This test exercises GPU compute through Apple’s Metal API, and the newer RDNA architecture with its higher shader count and clock speeds produces a nearly threefold improvement in raw score.

The Geekbench OpenCL test shows an even larger relative margin. The RX 5500 XT posts 46965 against the Pro 460’s 15284, a 67.5 percent difference. This is the biggest percentage win for the RX 5500 XT in the head-to-head data. The OpenCL workload benefits from the RX 5500 XT’s higher FP32 throughput of 5.196 TFLOPS versus the Pro 460’s 1.858 TFLOPS, as well as its much wider memory bandwidth.

The Geekbench Vulkan test rounds out the comparison with the RX 5500 XT scoring 44191 and the Pro 460 scoring 16816, a 61.9 percent margin. Vulkan performance follows the same pattern as the other compute tests, reflecting the fundamental throughput advantage of the newer GPU. Across all three tests, the Pro 460 never comes within 60 percent of the RX 5500 XT, underscoring how far the architecture has advanced in the three years between their respective release dates.

The RX 5500 XT’s additional benchmark data reinforces its stronger position. Its PassMark G3D score of 9083 and PassMark GPU Compute score of 4446, along with DirectX 9, 10, 11, and 12 scores of 133, 46, 56, and 40 respectively, are not directly comparable to the Pro 460 since the older card lacks these entries. The RX 5500 XT also records a 3DMark Steel Nomad DX12 score of 1032, demonstrating modern API performance that the Pro 460 cannot match.
