AMD Radeon Pro 555X vs AMD Radeon RX 7700 Comparison

The AMD Radeon RX 7700 and the AMD Radeon Pro 555X occupy opposite ends of the performance spectrum, and the recorded data reflects a generational and architectural chasm between them. The RX 7700 is an active, high-throughput discrete solution built for modern workloads, while the Pro 555X is an end-of-life integrated part designed for portability in Apple laptops. Across the single head-to-head benchmark available in the database, the RX 7700 delivers a decisive victory, but the two cards diverge so sharply in every measurable category that they serve fundamentally different purposes. The following analysis breaks down where each unit wins, what separates their designs, and how the benchmark numbers quantify the gap.

Where Each One Wins

The AMD Radeon RX 7700 wins in every scenario where raw compute throughput and modern API support are the deciding factors. Its benchmark portfolio includes results from 3DMark, PassMark, and Geekbench, with an average score of 15852 across all recorded tests. The Pro 555X, by contrast, is only represented by three Geekbench entries (Metal, OpenCL, and Vulkan), and its average benchmark score sits at 13321. In the only direct comparison available, Geekbench OpenCL, the RX 7700 scores 106028 versus 12628 for the Pro 555X, a delta of 739.6%. This means the RX 7700 is roughly 8.4 times faster in that specific compute workload.

The Pro 555X does not win any head-to-head tests in the database. Its wins, if any, would come from qualitative advantages: it is an integrated part (IGP) with a 75 W TDP, requires no power connectors, and uses a PCIe 3.0 x8 interface, making it suitable for thin, power-constrained laptops. The RX 7700, with a 200 W TDP, dual-slot cooler, and two 8-pin power connectors, is not designed for such environments. The data shows the Pro 555X is positioned for compatibility and low power draw, while the RX 7700 is positioned for performance. In terms of production status, the Pro 555X is end-of-life, whereas the RX 7700 remains active, suggesting the latter is the forward-looking choice for new builds.

Architecture Differences

The two GPUs come from entirely different architectural eras. The RX 7700 uses the Navi 32 chip built on RDNA 3.0, fabricated on a 5 nm process at TSMC, with 28,100 million transistors on a 346 mm² die. The Pro 555X uses the Polaris 21 chip based on GCN 4.0, fabricated on a 14 nm process at GlobalFoundries, with only 3,000 million transistors on a 123 mm² die. The transistor density difference is stark: 81.2 million transistors per square millimeter for the RX 7700 versus 24.4 million for the Pro 555X, reflecting the massive leap in manufacturing technology.

Memory configurations reinforce the architectural split. The RX 7700 carries 16 GB of GDDR6 on a 256-bit bus, delivering 624.1 GB/s of bandwidth at 19.5 Gbps effective. The Pro 555X has 4 GB of GDDR5 on a 128-bit bus, yielding 94.08 GB/s at 5.9 Gbps effective. The RX 7700 also supports PCIe 4.0 x16, while the Pro 555X is limited to PCIe 3.0 x8. In terms of compute resources, the RX 7700 has 2560 shading units, 160 texture mapping units, 96 raster operation units, and 40 ray tracing cores. The Pro 555X has 768 shading units, 48 TMUs, and 16 ROPs, with no ray tracing cores at all. The RX 7700 supports DirectX 12 Ultimate (12_2), Vulkan 1.4, and OpenGL 4.6, while the Pro 555X is capped at DirectX 12 (12_0), Vulkan 1.3, and OpenGL 4.6.

Head-to-Head Benchmarks

The only direct benchmark in the database is Geekbench OpenCL, and the result is lopsided. The RX 7700 scores 106028, while the Pro 555X scores 12628, giving the RX 7700 a 739.6% advantage. To put that in context, the RX 7700's nearest rivals in the overall database include the AMD Radeon RX 9060 (average score 16014, delta of -1%), the NVIDIA GeForce RTX 3060 Ti (average score 16129, delta of -1.7%), and the AMD Radeon Pro W5500 (average score 15679, delta of 1.1%). The RX 7700 sits at the 58th percentile of all GPUs, while the Pro 555X sits at the 54th percentile, but those percentiles obscure the massive absolute difference: the RX 7700's average benchmark score of 15852 is roughly 19% higher than the Pro 555X's 13321.

Looking at the RX 7700's individual results, it posts 2865 in 3DMark Steel Nomad DX12, 20974 in PassMark G3D, 10963 in PassMark GPU Compute, and 106028 in Geekbench OpenCL. The Pro 555X, meanwhile, has no scores in those tests, only its Geekbench trio: 14479 in Metal, 12628 in OpenCL, and 12855 in Vulkan. Even the Pro 555X's best recorded result (14479 in Metal) is less than 15% of the RX 7700's OpenCL score. The data indicates the RX 7700 is not just faster; it is in a different performance class entirely, outpacing its own nearest rivals by single-digit percentages while leaving the Pro 555X far behind.

The Verdict

The data points to a clear verdict for different audiences. The AMD Radeon RX 7700 is the choice for anyone building a desktop system that demands high compute throughput, modern API support, and future-proofing. Its 739.6% lead over the Pro 555X in Geekbench OpenCL, combined with its active production status and support for DirectX 12 Ultimate, makes it suitable for gaming, content creation, and other GPU-intensive tasks. Its nearest rivals, such as the RTX 3060 Ti (delta of -1.7%) and the RX 9060 (delta of -1%), show that it competes in the upper midrange tier of current GPUs.

The AMD Radeon Pro 555X, by contrast, is a legacy part for legacy systems. Its 75 W TDP, integrated form factor, and PCIe 3.0 x8 interface indicate it was designed for compact laptops where power efficiency and space are paramount, not for raw performance. Its 54th percentile ranking, while not far below the RX 7700's 58th percentile, is misleading because the absolute scores are drastically lower. For users with a machine already containing a Pro 555X, the data shows it can still handle basic compute tasks via OpenCL, Metal, and Vulkan, but it is not a viable option for modern high-end workloads. In short, the RX 7700 wins on every metric that matters for performance, while the Pro 555X wins only on portability and power draw, which are not benchmark categories.

Specification Differences

The two cards differ in nearly every specification field. The RX 7700 uses a 5 nm process at TSMC with 28,100 million transistors on a 346 mm² die, while the Pro 555X uses a 14 nm process at GlobalFoundries with 3,000 million transistors on a 123 mm² die. The RX 7700 has a base clock of 1900 MHz, a boost clock of 2459 MHz, and a game clock of 2041 MHz, plus memory at 2438 MHz (19.5 Gbps effective). The Pro 555X has no listed base, boost, or game clocks, only a memory clock of 1470 MHz (5.9 Gbps effective). Memory capacity is 16 GB of GDDR6 versus 4 GB of GDDR5, with bus widths of 256-bit versus 128-bit, and bandwidths of 624.1 GB/s versus 94.08 GB/s.

Compute resources differ as well: the RX 7700 has 2560 shading units, 160 TMUs, 96 ROPs, and 40 RT cores; the Pro 555X has 768 shading units, 48 TMUs, and 16 ROPs. Pixel rates are 236.1 GPixel/s versus 14.51 GPixel/s, texture rates are 393.4 GTexel/s versus 43.54 GTexel/s, and FP32 performance is 25.18 TFLOPS versus 1,393.2 GFLOPS. The RX 7700 has a 200 W TDP, dual-slot cooler, 2x 8-pin power connectors, and a suggested 550 W PSU, while the Pro 555X has a 75 W TDP, is an IGP, and requires no power connectors. Bus interfaces are PCIe 4.0 x16 versus PCIe 3.0 x8. Display outputs are 1x HDMI 2.1a, 2x DisplayPort 2.1, and 1x USB Type-C for the RX 7700, versus "Portable Device Dependent" for the Pro 555X. Finally, the RX 7700 supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the Pro 555X supports DirectX 12 (12_0) and Vulkan 1.3; both support OpenGL 4.6.
