AMD Radeon Pro WX 7100 vs Intel Arc A550M Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive performance gap between the Intel Arc A550M and the AMD Radeon Pro WX 7100. Across the two shared benchmark tests, the Intel part wins both, and the margin is substantial in each case.

In Geekbench OpenCL, the Intel Arc A550M scores 49894 against 40148 for the AMD Radeon Pro WX 7100. That is a 24.3% advantage for Intel. The gap is nearly identical in Geekbench Vulkan, where the Arc A550M posts 49580 versus 39683, a 24.9% lead. Both tests measure raw compute throughput, and the Intel part is consistently ahead by roughly a quarter.

Context from the database's nearest rivals helps interpret these scores. The Arc A550M's average benchmark score is 49737, placing it at the 86th percentile of all GPUs. Its closest rival in the database is the NVIDIA GeForce RTX 5070 Ti at 49957, a delta of -0.4%, meaning the Intel part trails that card by less than half a percent. It also sits just 0.5% behind the AMD Radeon RX Vega 64 (50001) and 2.4% behind the AMD Radeon RX 6900 XT (50951). Meanwhile, it leads the AMD Radeon RX 6800 XT (48477) by 2.6%. In short, the Arc A550M is competing in the company of high-end desktop cards from the previous generation, despite being a mobile part.

The AMD Radeon Pro WX 7100, by contrast, averages 40063 across its benchmark results, which lands it at the 82nd percentile. Its nearest rival is the AMD Radeon Pro 580 at 40318, a delta of -0.6%. It also trails the NVIDIA GeForce RTX 5070 by 0.8% (40377) but beats the NVIDIA RTX A500 Mobile by 1.3% (39568) and the AMD Radeon Pro 575 by 1.3% (39555). The WX 7100 is therefore a mid-pack professional card, comfortably above entry-level mobile workstation parts but far below the tier the Arc A550M occupies.

The head-to-head delta of 24.3% in OpenCL and 24.9% in Vulkan is not a marginal difference. It places the Intel part in a completely different performance class. The WX 7100's best result in any test is 40357 in Geekbench Metal, but the Arc A550M was not measured in Metal, so no direct comparison exists there. For the two APIs where both were tested, the Intel card wins by a wide margin.

Where Each One Wins

The Intel Arc A550M wins in OpenCL and Vulkan, which are the two cross-vendor APIs most relevant to general compute and modern graphics workloads. Its OpenCL score of 49894 and Vulkan score of 49580 are close to each other, indicating balanced performance across different compute interfaces. The 24.3% and 24.9% leads over the WX 7100 mean that for any application using either API, the Intel part should deliver noticeably higher throughput.

The AMD Radeon Pro WX 7100 has no benchmark win against the Arc A550M in the shared tests. However, the data does show one area where it has an exclusive presence: Metal. The WX 7100 scores 40357 in Geekbench Metal, which is actually its highest result of the three tests recorded for it. The Arc A550M has no Metal score in the database, so on Apple platforms or in Metal-only workloads, the WX 7100 is the only one of the two with measurable performance. That said, its Metal score is still lower than the Arc A550M's OpenCL and Vulkan scores, so it is not faster in absolute terms, just present in an API the Intel card lacks.

For professional use cases, the WX 7100's single-slot form factor and 4x DisplayPort 1.4a outputs make it suited to multi-display workstation setups. The Arc A550M's display outputs are listed as portable device dependent, reflecting its mobile IGP nature. Neither card wins on raw compute; the Intel part dominates that. The WX 7100's strengths are in its form factor and output configuration, not its benchmark scores.

Architecture Differences

The two GPUs come from different architectural generations and foundries. The Intel Arc A550M uses the DG2-512 chip built on the Xe-HPG architecture, belonging to the Alchemist generation for Arc 5 Mobile. It is fabricated on a 6 nm process at TSMC. The die contains 21,700 million transistors on a 406 mm² die, yielding a transistor density of 53.4 million per mm².

The AMD Radeon Pro WX 7100 uses the Ellesmere chip based on GCN 4.0, part of the Radeon Pro Polaris generation. It is built on a 14 nm process at GlobalFoundries. The die holds 5,700 million transistors across 232 mm², for a density of 24.6 million per mm². The process node difference is stark: 6 nm versus 14 nm, which explains much of the density gap.

The Intel chip includes 16 dedicated ray tracing cores, while the AMD chip has none. This is a major feature difference for any workload involving ray-traced lighting or shadows. The Intel part also supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the AMD card supports DirectX 12 (12_0) and Vulkan 1.3. The feature level gap in DirectX matters for newer games and applications that require DX12 Ultimate features.

The FP16 throughput differs in a telling way. The Arc A550M delivers 16.79 TFLOPS FP16 with a 2:1 ratio to FP32, meaning it can double its rate for half-precision work. The WX 7100 delivers 5.728 TFLOPS FP16 at a 1:1 ratio, identical to its FP32 rate. For machine learning inference or any half-precision compute, the Intel card has a significant advantage.

Specification Differences

The Intel Arc A550M has a 6 nm process node versus 14 nm for the AMD card. Transistor count is 21,700 million versus 5,700 million. Die size is 406 mm² versus 232 mm². Transistor density is 53.4M per mm² versus 24.6M per mm².

Clock speeds differ substantially. The Intel part has a 900 MHz base clock and 2050 MHz boost clock. The AMD card has a 1188 MHz base and 1243 MHz boost. The AMD part starts higher but has a much lower ceiling. Memory clocks are listed as 1750 MHz for both, but effective data rates differ: 14 Gbps for Intel's GDDR6 versus 7 Gbps for AMD's GDDR5.

Memory capacity is 8 GB on both, and bandwidth is 224.0 GB/s on both. The bus width differs: 128 bit on Intel versus 256 bit on AMD. The AMD card achieves the same bandwidth with a wider bus and slower memory, while the Intel card uses a narrower bus with faster GDDR6.

Shader resources differ in configuration. The Intel part has 2048 shading units, 128 TMUs, and 64 ROPs. The AMD part has 2304 shading units, 144 TMUs, and only 32 ROPs. The AMD card has more shaders and texture units, but half the ROPs. Pixel rate reflects this: 131.2 GPixel/s for Intel versus 39.78 GPixel/s for AMD. Texture rate is 262.4 GTexel/s versus 179.0 GTexel/s. FP32 compute is 8.397 TFLOPS for Intel versus 5.728 TFLOPS for AMD.

Power and physical specifications differ significantly. The Intel card has a 60 W TDP and is an IGP (integrated graphics processor) with no slot width. The AMD card has a 130 W TDP, is single-slot, requires 1x 6-pin power connector, and a 300 W suggested PSU. The AMD card measures 241 mm in length and 112 mm in height. The Intel card's dimensions are not recorded.

Bus interface differs: PCIe 4.0 x16 for Intel versus PCIe 3.0 x16 for AMD. Display outputs are portable device dependent for Intel versus 4x DisplayPort 1.4a for AMD. The AMD card has a release date of 2016-11-09 and a launch MSRP of 799 USD. The Intel card has no recorded release date or launch MSRP. The AMD card's predecessor is Radeon Pro GCN and successor is Radeon Pro Vega. Both are end-of-life products.

The Verdict

The data points to a clear choice for anyone comparing these two on compute performance. The Intel Arc A550M wins both shared benchmarks by roughly 24 to 25 percent, puts up scores near the NVIDIA GeForce RTX 5070 Ti and AMD Radeon RX Vega 64, and reaches the 86th percentile of all GPUs in the database. It also brings ray tracing support, a modern 6 nm process, DX12 Ultimate, Vulkan 1.4, and a 60 W TDP. For workloads that use OpenCL or Vulkan, the Arc A550M is the stronger card by a wide margin.

The AMD Radeon Pro WX 7100 is not without merit, but its strengths lie outside raw compute. It is a single-slot card with 4x DisplayPort 1.4a outputs, which suits multi-display professional setups. It also has a Metal score in the database, which the Intel card lacks. Its 82nd percentile standing and nearest rivals in the range of the AMD Radeon Pro 580 and NVIDIA RTX A500 Mobile show it belongs to a lower performance tier.

Who should pick which depends on the use case. If the priority is compute throughput, especially in OpenCL or Vulkan, the Intel Arc A550M is the obvious pick. Its 24.3% and 24.9% leads are too large to ignore. If the requirement is a single-slot workstation card with multiple DisplayPort outputs and Metal support, the Radeon Pro WX 7100 is the only one of the two that fits that description. But the benchmark data does not support choosing the AMD card for performance reasons. The Intel part is faster in every test where both were measured.
