AMD Radeon Pro 555 vs AMD Radeon RX Vega 11 Comparison

Head-to-Head Benchmarks

The benchmark data presents a clear, consistent picture: the AMD Radeon RX Vega 11 outperforms the AMD Radeon Pro 555 across every single test recorded in this comparison. This is not a narrow victory, nor one isolated to a single API. The wins are uniform across Metal, OpenCL, and Vulkan, indicating a fundamental performance advantage rather than a workload-specific quirk.

In the geekbench_metal test, the RX Vega 11 scores 17086 against the Pro 555’s 16236. That translates to a 5.2% lead — a solid margin, but not an overwhelming one. The gap widens in compute-oriented workloads. Under geekbench_opencl, the RX Vega 11 posts 12525 versus 11682, a 7.2% advantage. The most decisive result comes in geekbench_vulkan, where the RX Vega 11 reaches 13543 while the Pro 555 manages only 12303 — a 10.1% lead. For a comparison between an integrated graphics processor and a discrete mobile GPU, that magnitude of victory in the Vulkan test is noteworthy.

The aggregate data reinforces this trend. The RX Vega 11’s average benchmark score sits at 14385, while the Pro 555 averages 13407 — a difference of roughly 978 points. In percentile terms against all GPUs, the RX Vega 11 lands at the 56th percentile, while the Pro 555 sits at the 54th. Both are mid-pack performers, but the RX Vega 11 consistently holds the higher ground.

The nearest-rival data for each card provides additional context. The RX Vega 11’s average score of 14385 places it narrowly ahead of the NVIDIA GeForce GTX TITAN (14373, a 0.1% delta) and just behind the NVIDIA GeForce GTX 965M (14404, a -0.1% delta). It also edges out the AMD Radeon Vega 11 (14352, 0.2%) and the Intel Iris Xe MAX Graphics (14315, 0.5%). The Pro 555, meanwhile, with its 13407 average, sits between the AMD Radeon HD 8950M (13376, 0.2%) and the NVIDIA P106-090 (13470, -0.5%), while also being close to the AMD Radeon RX 5500M (13356, 0.4%) and AMD FirePro M6100 (13354, 0.4%). The RX Vega 11 is competing in a slightly higher performance tier than the Pro 555.

Where Each One Wins

The head-to-head results show three wins for the RX Vega 11 and zero for the Pro 555. There is no test in this dataset where the Pro 555 comes out ahead. That said, the margin of victory varies by workload, and that variance tells a story about each card’s strengths.

The RX Vega 11’s largest win is in Vulkan, where it leads by 10.1%. This suggests the newer GCN 5.0 architecture handles Vulkan’s explicit, low-overhead API particularly well relative to the older GCN 4.0 design in the Pro 555. The OpenCL result, a 7.2% lead, shows that general-purpose compute on the RX Vega 11 is also meaningfully stronger. The Metal result, at 5.2%, is the closest contest, indicating that Apple’s API narrows the gap somewhat — perhaps due to driver maturity or the Pro 555’s positioning as a Mac-oriented part.

For the Pro 555, there are no benchmark wins to point to, but the data does hint at areas where the deficit is smaller. In Metal, the delta is the tightest, so macOS users might find the experience more comparable than the raw specs suggest. Still, the benchmark results are unambiguous: the RX Vega 11 wins every recorded test, and the Pro 555’s best case is merely a smaller loss.

Architecture Differences

The two GPUs come from different architectural generations and are built for different roles, though both hail from AMD. The RX Vega 11 is based on the Picasso chip, using the GCN 5.0 architecture on a 12 nm process at GlobalFoundries. The Pro 555 uses the Polaris 21 chip, with the older GCN 4.0 architecture on a 14 nm process, also at GlobalFoundries.

Process node differences are modest — 12 nm versus 14 nm — but the transistor counts diverge sharply. The RX Vega 11 packs 4,940 million transistors on a 210 mm² die, yielding a density of 23.5M transistors per mm². The Pro 555 carries 3,000 million transistors on a 123 mm² die, with a density of 24.4M per mm². Interestingly, the Pro 555 is actually denser per square millimeter, but the RX Vega 11’s much larger die gives it a substantial raw transistor advantage.

Core configurations differ in ways that explain the performance gap. The RX Vega 11 has 704 shading units, 44 texture mapping units, and 8 ROPs. The Pro 555 has more of each in some categories: 768 shading units, 48 TMUs, and 16 ROPs. Despite having fewer shading units and TMUs, the RX Vega 11 still wins in benchmarks, which points to clock speeds and memory architecture as decisive factors.

Clock data is partially unavailable for the Pro 555 — base and boost clocks are not listed — but the RX Vega 11 has a base of 300 MHz and a boost of 1400 MHz. The memory situation is starkly different. The RX Vega 11 uses system-shared memory, with bandwidth described as "System Dependent." The Pro 555 has 2 GB of dedicated GDDR5 memory on a 128-bit bus, delivering 81.60 GB/s of bandwidth at an effective 5.1 Gbps. The Pro 555’s dedicated memory is a clear advantage in theory, yet the benchmark results do not reflect that advantage.

Rates tell a mixed story. The RX Vega 11 achieves a pixel rate of 11.20 GPixel/s and a texture rate of 61.60 GTexel/s. The Pro 555 posts 13.60 GPixel/s and 40.80 GTexel/s. So the Pro 555 wins on pixel fill rate, but the RX Vega 11 dominates texture fill. In floating-point compute, the RX Vega 11 delivers 1.971 TFLOPS (FP32) and 3.942 TFLOPS (FP16 at 2:1 ratio). The Pro 555 delivers 1,305.6 GFLOPS (FP32) and the same 1,305.6 GFLOPS for FP16 (1:1 ratio). The RX Vega 11’s FP32 output is roughly 51% higher, and its FP16 capability is three times greater thanks to the 2:1 ratio.

Power consumption differs dramatically. The RX Vega 11 is rated at 15 W TDP, while the Pro 555 draws 75 W. The RX Vega 11 is an IGP with no power connectors and a motherboard-dependent display output, whereas the Pro 555 is also listed as IGP slot width but uses a PCIe 3.0 x8 bus interface and portable-device-dependent outputs. Both are end-of-life products, with the RX Vega 11 released in July 2019 and the Pro 555 in June 2017.

API support is nearly identical: both support DirectX 12 (12_1 for the RX Vega 11, 12_0 for the Pro 555), OpenGL 4.6, and Vulkan 1.3. The DirectX feature level difference is minor but notable — 12_1 versus 12_0 — implying the RX Vega 11 has slightly newer feature support.

The Verdict

The data is unequivocal. The AMD Radeon RX Vega 11 wins all three head-to-head benchmarks, with deltas ranging from 5.2% to 10.1%. Its average benchmark score of 14385 is 7.3% higher than the Pro 555’s 13407. Its percentile ranking is higher (56th versus 54th). For any user choosing strictly on measured performance, the RX Vega 11 is the superior part.

The Pro 555 does have redeeming qualities in the data. It features dedicated 2 GB GDDR5 memory with 81.60 GB/s bandwidth, which is a more predictable memory subsystem than the RX Vega 11’s system-shared, system-dependent approach. It also has more shading units (768 versus 704), more TMUs (48 versus 44), more ROPs (16 versus 8), and a higher pixel rate (13.60 versus 11.20 GPixel/s). These specs suggest the Pro 555 could be preferable in memory-bandwidth-sensitive or pixel-heavy tasks, but no benchmark in this dataset confirms that.

The RX Vega 11 wins on texture rate (61.60 versus 40.80 GTexel/s), FP32 compute (1.971 TFLOPS versus 1,305.6 GFLOPS), and FP16 compute (3.942 versus 1,305.6 GFLOPS). It also does so at a fraction of the power: 15 W versus 75 W. On a per-watt basis, the RX Vega 11 is dramatically more efficient in this dataset.

Who should pick which? If the choice is based purely on the benchmark results presented here, the RX Vega 11 is the clear winner. It is faster in every recorded test, uses far less power, and achieves a higher percentile standing. The Pro 555 might be the only option in a specific laptop or Mac configuration, but from a pure performance standpoint, the data does not favor it. Users needing a GPU for Vulkan-heavy workloads should especially favor the RX Vega 11, given its 10.1% lead in that test. Users constrained to a system that only supports the Pro 555 will find it adequate but measurably slower than the RX Vega 11 in all recorded benchmarks.
