AMD Radeon Pro 460 vs AMD Radeon RX 5700 XT Comparison

# AMD Radeon Pro 460 vs AMD Radeon RX 5700 XT

The AMD Radeon Pro 460 and AMD Radeon RX 5700 XT represent two distinct eras of AMD graphics, separated by architecture, process node, and design intent. The Pro 460, a 14 nm GCN 4.0 part from the Radeon Pro Mac (400 Series) generation, targets mobile integrated graphics with a 35 W TDP, while the RX 5700 XT, a 7 nm RDNA 1.0 part from the Navi (RX 5000) series, is a dual-slot desktop card with a 225 W TDP. Benchmark data shows a split: the RX 5700 XT dominates in Geekbench Metal and Vulkan with scores of 74647 and 68310, respectively, while the Pro 460 wins in Geekbench OpenCL with 15284 versus 9524. The average benchmark scores tell a curious story—the Pro 460 averages 17509, slightly ahead of the RX 5700 XT's 16361, despite the latter's massive lead in two of three head-to-head tests—underscoring how workload-specific differences can invert overall rankings.

The Verdict

The data points to a clear performance hierarchy: the AMD Radeon RX 5700 XT is the superior GPU for Metal and Vulkan workloads, with scores of 74647 and 68310 respectively, representing a 72.6% and 75.4% advantage over the Pro 460 in those tests. For users running applications that leverage DirectX 12 (12_1) or Vulkan 1.4, the RX 5700 XT is the only logical choice—its 2560 shading units, 160 TMUs, and 64 ROPs provide a hardware foundation that the Pro 460's 1024 shading units, 64 TMUs, and 16 ROPs cannot match. The RX 5700 XT also offers 8 GB of GDDR6 memory on a 256-bit bus with 448.0 GB/s bandwidth, compared to 4 GB GDDR5 on a 128-bit bus with 81.28 GB/s on the Pro 460.

However, the Pro 460 is not without a niche. Its Geekbench OpenCL score of 15284 beats the RX 5700 XT's 9524 by 60.5%, a significant margin that suggests OpenCL compute workloads favor the older GCN architecture. This is reinforced by the Pro 460's average benchmark score of 17509, which is 0.7% higher than the RX 5700 XT's 16361 and places it in the 61st percentile versus the RX 5700 XT's 59th percentile among all GPUs. For users constrained by power—the Pro 460 draws 35 W versus 225 W—or needing an integrated form factor (IGP slot width, no power connectors), the Pro 460 presents a viable option despite its age. The verdict is straightforward: for gaming, modern APIs, and raw throughput, pick the RX 5700 XT; for OpenCL compute in a low-power, integrated package, the Pro 460 holds a measurable edge.

Where Each One Wins

The RX 5700 XT wins decisively in Metal and Vulkan benchmarks, which are critical for macOS gaming and cross-platform graphics. Its Geekbench Metal score of 74647 dwarfs the Pro 460's 20426, and the Vulkan gap is similarly stark: 68310 versus 16816. This aligns with the RX 5700 XT's richer feature set—it supports DirectX 12 (12_1) and Vulkan 1.4, while the Pro 460 only reaches DirectX 12 (12_0) and Vulkan 1.3. The RX 5700 XT also brings PCIe 4.0 x16 connectivity versus PCIe 3.0 x8, doubling the bus lanes and doubling the transfer rate, which benefits data-intensive workloads. Its 121.9 GPixel/s pixel rate and 304.8 GTexel/s texture rate outpace the Pro 460's 14.51 GPixel/s and 58.05 GTexel/s by factors of 8.4x and 5.3x, respectively.

The Pro 460's win in OpenCL is the outlier that defines its use case. With an FP32 throughput of 1.858 TFLOPS and FP16 at 1.858 TFLOPS (1:1 ratio), it delivers balanced compute, whereas the RX 5700 XT's FP32 is 9.754 TFLOPS but FP16 jumps to 19.51 TFLOPS (2:1 ratio), indicating a different compute balance that evidently does not translate to OpenCL efficiency. The Pro 460's OpenCL score of 15284 is 60.5% higher than the RX 5700 XT's 9524, suggesting that GCN 4.0's compute scheduler handles OpenCL kernels more effectively than RDNA 1.0's. This makes the Pro 460 the better choice for OpenCL-specific workloads, despite its lower absolute specifications. Additionally, the Pro 460's 61st percentile ranking versus the RX 5700 XT's 59th indicates that in aggregate benchmark terms, the older card sits slightly higher in the global distribution—a nuance that favors the Pro 460 for mixed or OpenCL-heavy usage.

Architecture Differences

The two GPUs share a manufacturer but diverge at nearly every architectural level. The Pro 460 uses the Baffin chip built on GCN 4.0 architecture, fabricated on a 14 nm process at GlobalFoundries. It integrates 3,000 million transistors on a 123 mm² die, yielding a transistor density of 24.4M per mm². The RX 5700 XT uses the Navi 10 chip on RDNA 1.0 architecture, fabricated on a 7 nm process at TSMC. It packs 10,300 million transistors into a 251 mm² die, achieving a transistor density of 41.0M per mm²—nearly double the density and over three times the transistor count.

Clock speeds reflect the process node advantage. The RX 5700 XT runs at a base of 1605 MHz, a boost of 1905 MHz, and a game clock of 1755 MHz, while the Pro 460 operates at 850 MHz base and 907 MHz boost. Memory clocks follow suit: the RX 5700 XT's GDDR6 runs at 1750 MHz (14 Gbps effective) versus the Pro 460's GDDR5 at 1270 MHz (5.1 Gbps effective). The memory subsystem differs dramatically—8 GB on a 256-bit bus versus 4 GB on a 128-bit bus, with bandwidth of 448.0 GB/s versus 81.28 GB/s, a 5.5x difference.

The compute units scale accordingly: the RX 5700 XT has 2560 shading units, 160 TMUs, and 64 ROPs, compared to 1024, 64, and 16 on the Pro 460. Neither card features ray tracing or tensor cores, so both rely purely on raster and compute hardware. Power delivery is another differentiator: the Pro 460 is an IGP with no power connectors and a 35 W TDP, while the RX 5700 XT is a dual-slot card with 1x 6-pin + 1x 8-pin connectors, a 225 W TDP, and a suggested PSU of 550 W. The RX 5700 XT's physical dimensions are 272 mm in length, 111 mm in height, and 36 mm in width, while the Pro 460's dimensions are listed as null, reflecting its integrated nature. The RX 5700 XT also supports a broader API set, including DirectX 12 (12_1) and Vulkan 1.4, whereas the Pro 460 is capped at DirectX 12 (12_0) and Vulkan 1.3.

Head-to-Head Benchmarks

The head-to-head data across three Geekbench tests reveals a lopsided contest with one notable upset. In Geekbench Metal, the RX 5700 XT scores 74647 against the Pro 460's 20426, a delta of -72.6% from the Pro 460's perspective. This is the larger of the RX 5700 XT's two wins and reflects the architectural gap in raw shading throughput—the RX 5700 XT's 2560 shading units and 160 TMUs provide over twice the execution resources of the Pro 460's 1024 shading units and 64 TMUs, further amplified by a 121.9 GPixel/s pixel rate versus 14.51 GPixel/s.

Geekbench Vulkan shows a similar pattern: the RX 5700 XT scores 68310 versus 16816 for the Pro 460, a delta of -75.4%. This is the RX 5700 XT's largest percentage win and aligns with its superior Vulkan 1.4 support versus the Pro 460's Vulkan 1.3. The 5.5x memory bandwidth advantage (448.0 GB/s versus 81.28 GB/s) likely contributes heavily here, as Vulkan workloads often stress memory throughput. The RX 5700 XT's boost clock of 1905 MHz versus the Pro 460's 907 MHz also plays a role, doubling the instruction issue rate.

The Pro 460's sole victory comes in Geekbench OpenCL, where it scores 15284 against the RX 5700 XT's 9524, a delta of 60.5% in its favor. This is a striking result given that the RX 5700 XT has 2.5x the shading units and 5.25x the FP32 throughput (9.754 TFLOPS versus 1.858 TFLOPS). The win suggests that GCN 4.0's compute architecture, with its 1:1 FP16 ratio, is better optimized for OpenCL's execution model than RDNA 1.0's 2:1 FP16 ratio. It also explains the Pro 460's higher average benchmark score of 17509, which, combined with its 61st percentile ranking, shows that OpenCL performance can be a decisive factor in overall assessments. The RX 5700 XT's average of 16361, dragged down by its OpenCL result, still places it in the 59th percentile, but the data indicates that for OpenCL-specific tasks, the older, lower-power Pro 460 is the better performer.
