Architecture Differences

The AMD Radeon RX 7700 is built on the Navi 32 chip using RDNA 3.0 architecture, fabricated on a 5 nm process at TSMC. The AMD Radeon Pro 555 uses the Polaris 21 chip with GCN 4.0 architecture on a 14 nm process at GlobalFoundries. This generational process difference is substantial: the RX 7700 packs 28,100 million transistors into a 346 mm² die, achieving a transistor density of 81.2M per mm². The Pro 555 contains 3,000 million transistors on a 123 mm² die, with a density of 24.4M per mm². The newer RDNA 3.0 design allows for nearly 11.4 times the transistor count in roughly 2.8 times the die area.

The RX 7700 is part of the Radeon RX 7000 series and the Navi III (RX 7000) generation, with the codename Wheat Nas. It has a predecessor in Navi II and a successor in Navi IV. The Pro 555 belongs to the Radeon Pro Mac (500 Series) generation with no recorded codename, predecessor, or successor. The RX 7700's bus interface is PCIe 4.0 x16, while the Pro 555 uses PCIe 3.0 x8.

Feature support diverges sharply. The RX 7700 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Pro 555 supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3. The RX 7700 includes 40 ray tracing cores, while the Pro 555 has none recorded. Neither card lists tensor cores.

The RX 7700 has a dual-slot form factor with 2x 8-pin power connectors and a suggested PSU of 550 W. The Pro 555 is an IGP (integrated graphics processor) with no power connectors and no suggested PSU. Display outputs also differ: the RX 7700 offers 1x HDMI 2.1a, 2x DisplayPort 2.1, and 1x USB Type-C, while the Pro 555 is described as portable device dependent.

Physical dimensions are only recorded for the RX 7700: 267 mm length, 135 mm height, and 50 mm width. The Pro 555 has no recorded dimensions.

The Verdict

The recorded data shows a decisive performance hierarchy. The RX 7700 wins the only shared head-to-head benchmark, Geekbench OpenCL, with a 807.6% advantage. It also holds a higher average benchmark score, 15852 versus 13407, and a higher percentile ranking, 58 versus 54. For any workload captured by these metrics, the RX 7700 is the clear choice.

The Pro 555 is an end-of-life mobile IGP from 2017 with 2 GB of GDDR5 memory and GCN 4.0 architecture. Its nearest rivals in the database, the AMD Radeon HD 8950M (13376), AMD Radeon RX 5500M (13356), and AMD FirePro M6100 (13354), all score within 0.4% of it, placing it in a performance tier roughly 18% below the RX 7700's average. The RX 7700, by contrast, trades within 1.7% of the NVIDIA GeForce RTX 3060 Ti and 1.1% of the AMD Radeon Pro W5500 (15679).

The RX 7700 is suited to desktop systems with a 550 W suggested PSU, while the Pro 555 is a portable device dependent IGP. Users requiring ray tracing hardware will find it only in the RX 7700, as the Pro 555 has no RT cores recorded. Those on a PCIe 3.0 x8 platform with legacy GCN 4.0 needs might consider the Pro 555, but benchmark results indicate it trails the RX 7700 by a wide margin in every measured category.

Specification Differences

The RX 7700 and Pro 555 differ in nearly every recorded specification. The RX 7700 has 2560 shading units, 160 TMUs, and 96 ROPs, compared to 768 shading units, 48 TMUs, and 16 ROPs on the Pro 555. The RX 7700 also has 40 RT cores; the Pro 555 has none.

Memory configuration is a major divider. The RX 7700 uses 16 GB of GDDR6 on a 256-bit bus with 624.1 GB/s bandwidth. The Pro 555 uses 2 GB of GDDR5 on a 128-bit bus with 81.60 GB/s bandwidth. Memory clocks are 2438 MHz (19.5 Gbps effective) for the RX 7700 versus 1275 MHz (5.1 Gbps effective) for the Pro 555.

Compute throughput differs by an order of magnitude. The RX 7700 delivers 25.18 TFLOPS FP32 and 25.18 TFLOPS FP16 (1:1). The Pro 555 delivers 1,305.6 GFLOPS FP32 and 1,305.6 GFLOPS FP16 (1:1). Pixel rate is 236.1 GPixel/s versus 13.60 GPixel/s, and texture rate is 393.4 GTexel/s versus 40.80 GTexel/s.

Power and physical specifications diverge as well. The RX 7700 has a TDP of 200 W, a dual-slot width, and 2x 8-pin power connectors. The Pro 555 has a TDP of 75 W, an IGP slot width, and no power connectors. The RX 7700 uses PCIe 4.0 x16; the Pro 555 uses PCIe 3.0 x8.

Process and manufacturing details differ: 5 nm TSMC versus 14 nm GlobalFoundries. Transistor counts are 28,100 million versus 3,000 million, and die sizes are 346 mm² versus 123 mm². Transistor density is 81.2M per mm² versus 24.4M per mm².

API support shows the RX 7700 with DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the Pro 555 has DirectX 12 (12_0) and Vulkan 1.3. Both support OpenGL 4.6. The RX 7700 has a base clock of 1900 MHz, boost clock of 2459 MHz, and game clock of 2041 MHz; the Pro 555 has no recorded clocks for base, boost, or game.

Head-to-Head Benchmarks

The database contains one direct comparison between the two GPUs: Geekbench OpenCL. The RX 7700 scores 106028, while the RX 555 scores 11682. This is a 807.6% delta in favor of the RX 7700, the largest recorded single-test advantage for either card.

Beyond the head-to-head, the broader benchmark suite for the RX 7700 provides context. Its best result is the Geekbench OpenCL score of 106028, followed by the 3DMark Steel Nomad DX12 score of 2865. Passmark results include G3D at 20974, GPU Compute at 10963, DirectX 11 at 186, DirectX 9 at 261, DirectX 10 at 92, DirectX 12 at 96, and G2D at 1206. The RX 7700's average benchmark score of 15852 places it in the same neighborhood as its nearest rivals, with the AMD Radeon R9 370X at 15862 (0.1% higher) and the Radeon Pro W5500 at 15679 (1.1% lower).

The Pro 555 has three recorded benchmarks: Geekbench OpenCL at 11682, Geekbench Vulkan at 12303, and Geekbench Metal at 16236. Its average score of 13407 sits just above the AMD Radeon HD 8950M at 13376 (0.2% lower) and just below the NVIDIA P106-090 at 13470 (0.5% higher).

The data shows the RX 7700 is not merely faster in raw compute; it also demonstrates a stronger performance headroom in modern API support. DirectX 12 Ultimate and Vulkan 1.4 on the RX 7700 versus DirectX 12 (12_0) and Vulkan 1.3 on the Pro 555 align with its newer architecture. The RX 7700 wins the sole head-to-head test decisively, and its higher average score, higher percentile, and superior specifications across every measured dimension confirm a clear performance ordering in the database. The Pro 555, while functional for its era, is end-of-life and operates in a different performance class.
