AMD Radeon Pro WX 8200 vs Intel Arc A550M Comparison

Where Each One Wins

The benchmark database splits these two GPUs across two compute-oriented tests, and the results are unambiguous. The AMD Radeon Pro WX 8200 wins both recorded head-to-head comparisons, taking the Geekbench OpenCL test with a score of 69,774 against Intel's 49,894, a 39.8% advantage, and the Vulkan test with 69,076 against 49,580, a 39.3% lead. That gives the AMD part a clean 2-0 sweep in the database's head-to-head records.

The Intel Arc A550M does not hold a single winning position in any recorded benchmark. Its strength lies elsewhere: it is a mobile-class part with a 60 W thermal design power, designed for portable devices, whereas the AMD card is a dual-slot workstation board with a 230 W TDP and a 550 W suggested power supply. The data shows that the AMD card dominates raw compute throughput, but the Intel part occupies a completely different power and form-factor envelope, which matters for systems where the AMD card physically cannot fit or run.

Looking at the percentile rankings, the AMD Radeon Pro WX 8200 sits at the 90th percentile among all GPUs, while the Intel Arc A550M lands at the 86th percentile. That gap is smaller than the raw score delta suggests, because the Intel part's 49,737 average benchmark score still places it well above most of the field. The AMD card's 69,870 average is higher, but both are firmly in the upper tier of recorded GPUs.

Architecture Differences

The two GPUs come from opposite ends of the design spectrum. The AMD Radeon Pro WX 8200 uses the Vega 10 chip on the GCN 5.0 architecture, built on a 14 nm process from GlobalFoundries. The die measures 495 mm² and packs 12,500 million transistors, which works out to a transistor density of 25.3 million per square millimeter. It is a large, power-hungry workstation chip from the Radeon Pro Polaris generation, released in August 2018.

The Intel Arc A550M uses the DG2-512 chip on the Xe-HPG architecture, fabricated on a 6 nm process at TSMC. Its die is smaller at 406 mm², but it holds 21,700 million transistors, yielding a much higher density of 53.4 million per square millimeter. This is a newer, denser design from the Alchemist Arc 5 Mobile generation, and it is an integrated graphics package with an IGP slot width, meaning it is soldered onto a portable device's motherboard rather than installed as a discrete card.

Memory subsystems differ sharply. The AMD card uses 8 GB of HBM2 on a 2048-bit bus, delivering 512.0 GB/s of bandwidth. The Intel part also has 8 GB, but it is GDDR6 on a 128-bit bus, providing 224.0 GB/s, less than half the bandwidth. Clock behavior tells a similar story: the AMD part runs at a 1200 MHz base and 1500 MHz boost with memory at 1000 MHz (2 Gbps effective), while the Intel part has a 900 MHz base, a much higher 2050 MHz boost, and memory at 1750 MHz (14 Gbps effective). The Intel chip compensates for its narrow bus with faster memory clocks, but it still trails in total bandwidth.

Compute resources are lopsided. The AMD card fields 3,584 shading units, 224 texture mapping units, and 64 render output units. The Intel part has only 2,048 shading units and 128 TMUs, but it also has 16 ray tracing cores, which the AMD card lacks entirely. Both have 64 ROPs. The AMD card's pixel rate is 96.00 GPixel/s versus 131.2 GPixel/s for Intel, so the Intel part wins on pixel throughput despite fewer TMUs. The AMD card posts a texture rate of 336.0 GTexel/s versus 262.4 GTexel/s for Intel.

Floating-point performance favors AMD. The WX 8200 delivers 10.75 TFLOPS FP32 and 21.50 TFLOPS FP16 (2:1), while the A550M delivers 8.397 TFLOPS FP32 and 16.79 TFLOPS FP16 (2:1). The AMD card is roughly 28% ahead in FP32 and 28% ahead in FP16, a consistent margin that shows up in the compute benchmarks.

Feature support also differs. The Intel part supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the AMD card supports DirectX 12 (12_1) and Vulkan 1.3. Both support OpenGL 4.6. The Intel part's ray tracing cores and newer API support give it modern rendering features, but the AMD card's raw compute throughput is the deciding factor in the recorded benchmarks.

Head-to-Head Benchmarks

The Geekbench OpenCL test is the largest gap between the two. The AMD Radeon Pro WX 8200 scores 69,774, and the Intel Arc A550M scores 49,894. The AMD card leads by 39.8%, a decisive margin that reflects its higher shading unit count, wider memory bus, and greater FP32 throughput. In practical terms, OpenCL workloads that scale with raw compute will see the AMD card finish substantially faster.

The Vulkan test tells nearly the same story. The AMD card scores 69,076, and the Intel part scores 49,580, a 39.3% advantage for AMD. Vulkan is a lower-level API that can expose the Intel part's newer architecture more efficiently, but the data shows that the AMD card still holds a commanding lead. The Intel part's 16 ray tracing cores do not help in this benchmark, which is compute-focused rather than ray-tracing-focused.

Context from the nearest rivals helps frame these numbers. The AMD Radeon Pro WX 8200's average benchmark score of 69,870 sits within 0.4% of the NVIDIA RTX A3000 Mobile (70,140) and within 0.2% of the NVIDIA Quadro P6000 (69,986). It is 1.3% ahead of the NVIDIA CMP 90HX (69,000) and 1.4% behind the AMD Radeon RX 6600 LE (70,829). This places the WX 8200 in a tight cluster of high-end GPUs where a 1-2% swing separates them.

The Intel Arc A550M's average of 49,737 is 0.4% behind the NVIDIA GeForce RTX 5070 Ti (49,957) and 0.5% behind the AMD Radeon RX Vega 64 (50,001). It is 2.4% behind the AMD Radeon RX 6900 XT (50,951) but 2.6% ahead of the AMD Radeon RX 6800 XT (48,477). The Intel part is competitive with a set of desktop GPUs that have much higher power draws, which is notable given its 60 W mobile design.

The per-test deltas reinforce the average scores. The AMD card's 39.8% and 39.3% leads over Intel are far larger than any of the rival deltas in either GPU's nearest-rival list. This is not a close contest; the AMD card wins by a wide margin in the two recorded workloads.

The Verdict

The data supports a clear split decision based on use case. The AMD Radeon Pro WX 8200 is the right pick for compute-heavy workstation workloads where maximum raw throughput matters. Its 39.8% OpenCL lead and 39.3% Vulkan lead over the Intel Arc A550M are decisive, and its 512.0 GB/s memory bandwidth and 10.75 TFLOPS FP32 performance make it suitable for large data sets and dense compute tasks. It also carries the pedigree of a workstation-class product with four mini-DisplayPort 1.4a outputs, a 2,048-bit memory bus, and a dual-slot cooler, all consistent with a serious desktop compute card.

The Intel Arc A550M is the right pick for portable systems that need a capable GPU within a 60 W envelope. Its 2,050 MHz boost clock is high, its 131.2 GPixel/s pixel rate exceeds the AMD card's, and its 16 ray tracing cores and DirectX 12 Ultimate support give it modern gaming and rendering features that the AMD card lacks. The data shows it holds its own against desktop-class rivals like the Radeon RX 6900 XT, coming within 2.4% of that card's average score, despite drawing a fraction of the power and fitting into an integrated form factor.

Users who need raw compute in a desktop workstation should choose the AMD Radeon Pro WX 8200. Users who need a modern, feature-rich GPU in a portable device should choose the Intel Arc A550M. The two do not compete for the same physical space or power budget, and the benchmark results reflect that: the AMD card wins every recorded test, but the Intel part offers capabilities the AMD card simply does not have, such as ray tracing acceleration and a PCIe 4.0 interface.

The production status of both parts is end-of-life, so neither is a future-proof investment. The AMD card was released in August 2018 with a launch MSRP of 999 USD, while the Intel part has no recorded release date or MSRP in the database. For current workloads, the AMD card is the compute leader; for portable and modern-feature workloads, the Intel part is the only one that fits.
