AMD Radeon Pro 555X vs NVIDIA GeForce RTX 2060 Comparison

The Verdict

The NVIDIA GeForce RTX 2060 is the clear performance leader in this comparison. The data shows a decisive victory for the RTX 2060, which wins both head-to-head benchmarks by margins exceeding 400%. The AMD Radeon Pro 555X, by contrast, trails significantly in every measured metric, making it suitable only for workloads where the RTX 2060 is unavailable or where its integrated nature is a requirement.

The RTX 2060 should be the choice for anyone needing discrete graphics performance in a desktop context. Its average benchmark score of 15290 places it in the 58th percentile of all GPUs, while the Radeon Pro 555X sits at 13321 and the 54th percentile. The RTX 2060 also supports modern features like DirectX 12 Ultimate, hardware ray tracing cores, and tensor cores, none of which exist on the Radeon Pro 555X. The Radeon Pro 555X, with its IGP slot width and portable-device-dependent display outputs, is designed for Apple Mac systems and offers no upgrade path or desktop installation option.

Architecture Differences

The two GPUs come from fundamentally different architectural eras. The RTX 2060 uses the TU106 chip built on TSMC's 12 nm process, while the Radeon Pro 555X uses the Polaris 21 chip on GlobalFoundries' 14 nm node. The transistor counts reflect this gap: the RTX 2060 packs 10,800 million transistors on a 445 mm² die, whereas the Radeon Pro 555X has 3,000 million transistors on a 123 mm² die. Transistor density is nearly identical, 24.3M per mm² for the RTX 2060 versus 24.4M per mm² for the Radeon Pro 555X, meaning the performance difference comes from sheer scale rather than density efficiency.

The RTX 2060 is a Turing architecture part with 1920 shading units, 120 texture mapping units, 48 ROPs, 30 ray tracing cores, and 240 tensor cores. The Radeon Pro 555X uses GCN 4.0 with 768 shading units, 48 TMUs, and 16 ROPs, with no ray tracing or tensor core support. The Radeon Pro 555X does offer FP16 at a 1:1 ratio, matching its FP32 rate of 1,393.2 GFLOPS, while the RTX 2060 achieves FP16 at 12.90 TFLOPS through a 2:1 mechanism. The RTX 2060's FP32 throughput of 6.451 TFLOPS is more than 4.6 times the Radeon Pro 555X's 1,393.2 GFLOPS.

Memory configurations also diverge sharply. The RTX 2060 features 6 GB of GDDR6 on a 192-bit bus with 336.0 GB/s of bandwidth and 14 Gbps effective memory speed. The Radeon Pro 555X has 4 GB of GDDR5 on a 128-bit bus, delivering 94.08 GB/s at 5.9 Gbps effective. The RTX 2060's bandwidth advantage is roughly 3.6 times.

Head-to-Head Benchmarks

The head-to-head data contains two comparable tests, and the RTX 2060 wins both by staggering margins. In Geekbench OpenCL, the RTX 2060 scores 65014 against the Radeon Pro 555X's 12628, a delta of 414.8 percent. In Geekbench Vulkan, the RTX 2060 scores 65846 versus 12855, a delta of 412.2 percent. These are not incremental wins; they represent a completely different performance class.

The Radeon Pro 555X has one benchmark the RTX 2060 cannot match directly: Geekbench Metal, where it scores 14479. However, this is an Apple-specific API and does not factor into the cross-platform head-to-head comparison. The RTX 2060 also has a broader benchmark suite in the database, including PassMark scores across DirectX 9, 10, 11, 12, G2D, G3D, and GPU compute, plus a 3DMark Steel Nomad DX12 score of 1242. The Radeon Pro 555X only has Geekbench entries in the database, making its average benchmark score of 13321 based on a narrower set of measurements.

Context from the nearest rivals reinforces the gap. The RTX 2060's closest competitors are the GeForce GTX 580 (15283, 0 percent delta), AMD Radeon 680M (15270, 0.1 percent), GeForce RTX 3050 OEM (15199, 0.6 percent), and Radeon RX 7600 (15171, 0.8 percent). The Radeon Pro 555X sits near the GeForce GTX 480 (13300, 0.2 percent), AMD FirePro M6100 (13354, negative 0.2 percent), Radeon RX 5500M (13356, negative 0.3 percent), and Radeon HD 8950M (13376, negative 0.4 percent). In other words, the RTX 2060 competes with GPUs from the RTX 30-series and RX 7000-series generation, while the Radeon Pro 555X trades blows with hardware from the GTX 400-era and older mobile parts.

Where Each One Wins

The RTX 2060 wins in every scenario where performance matters. Its 6.451 TFLOPS FP32 throughput, 201.6 GTexel/s texture rate, and 80.64 GPixel/s pixel rate dwarf the Radeon Pro 555X's 1,393.2 GFLOPS, 43.54 GTexel/s, and 14.51 GPixel/s. In gaming, the RTX 2060's PassMark G3D score of 14111 and DirectX 11 score of 110 indicate strong legacy API performance, while its DirectX 12 score of 53 and 3DMark Steel Nomad score of 1242 show modern API readiness. The Radeon Pro 555X has no comparable gaming benchmark entries in the database.

The Radeon Pro 555X wins only in the context of its intended platform. As an IGP-class part with portable-device-dependent display outputs, it is designed for Mac laptops where the RTX 2060 cannot be installed. Its 75 W TDP and lack of power connectors make it suitable for systems with no discrete power delivery. Its Geekbench Metal score of 14479 is the only recorded benchmark where it has a unique result, reflecting Apple's Metal API support. For macOS-only workflows that rely on Metal, the Radeon Pro 555X is the only option in this pairing.

For compute workloads measured by OpenCL and Vulkan, the RTX 2060 is the only rational choice. The 414.8 percent OpenCL lead and 412.2 percent Vulkan lead are so large that any task using those APIs will complete more than five times faster on the RTX 2060. The RTX 2060's tensor cores also enable AI-adjacent workloads, and its 6 GB VRAM provides a 50 percent capacity advantage over the Radeon Pro 555X's 4 GB.
