Q: Which card has higher clock speeds?

A: The RX 6550M boosts to 2840 MHz with a base clock of 2000 MHz and a game clock of 2560 MHz. The W5700X has a base clock of 1243 MHz and a boost of 2040 MHz, meaning the mobile chip runs significantly faster across all clock states.

Architecture Differences

The architectural divide between these two AMD GPUs is substantial, reflecting a generational leap in design philosophy. The W5700X is built on the Navi 10 chip using RDNA 1.0 architecture, manufactured on TSMC’s 7 nm process. It packs 10,300 million transistors into a 251 mm² die, yielding a transistor density of 41.0M per mm². In contrast, the RX 6550M uses the Navi 24 chip on RDNA 2.0, fabricated on a more advanced 6 nm process from the same foundry. This smaller chip contains 5,400 million transistors on a 107 mm² die, achieving a higher density of 50.5M per mm².

The computing resources differ dramatically. The W5700X fields 2,560 shading units, 160 texture mapping units, and 64 raster operation pipelines. The RX 6550M, despite its mobile positioning, offers 1,024 shading units, 64 TMUs, and 32 ROPs — exactly half the TMUs and ROPs of the larger card. Notably, the RX 6550M includes 16 ray tracing cores, a feature entirely absent from the W5700X’s specifications. This gives the mobile chip hardware acceleration for ray-traced workloads, something the older workstation card cannot claim.

Memory architecture is another point of divergence. The W5700X uses a 256-bit memory bus with 16 GB of GDDR6 running at 1750 MHz (14 Gbps effective), producing 448.0 GB/s of bandwidth. The RX 6550M operates on a 64-bit bus with 4 GB of GDDR6 at 2250 MHz (18 Gbps effective), delivering 144.0 GB/s. The 3x bandwidth advantage of the W5700X is a direct consequence of its wider bus, while the RX 6550M compensates with higher memory clock speeds.

Clock behavior also differs fundamentally. The RX 6550M has a base clock of 2000 MHz and a boost of 2840 MHz, with a game clock of 2560 MHz. The W5700X starts at 1243 MHz base but boosts to 2040 MHz. This means the mobile GPU runs at significantly higher frequencies across the board, a hallmark of the more efficient 6 nm RDNA 2.0 design. The power envelope tells the story: the W5700X consumes 205 W and requires a 550 W suggested PSU, while the RX 6550M draws just 80 W with no separate power connectors and no PSU recommendation listed.

Head-to-Head Benchmarks

The two shared benchmark results paint a picture of near parity in one API and clear separation in another. In Geekbench OpenCL, the W5700X scores 43,810 against the RX 6550M’s 42,536, a 3% advantage for the desktop workstation card. This is a surprisingly close result given the W5700X’s superior memory bandwidth (448.0 GB/s vs. 144.0 GB/s) and higher shading unit count (2,560 vs. 1,024). The difference suggests that OpenCL workloads on the RX 6550M are highly efficient per compute unit, likely benefiting from the RDNA 2.0 architecture’s improved instruction scheduling and the much higher boost clock of 2840 MHz versus 2040 MHz.

The Vulkan result flips the script decisively. The RX 6550M achieves 50,867, defeating the W5700X’s 45,246 by a substantial 11.1% margin. This is the single largest performance gap between the two cards, and it favors the mobile GPU despite its smaller memory footprint and narrower bus. Vulkan’s low-level nature likely allows the RX 6550M’s higher clock speeds and newer architecture to shine, while the W5700X’s RDNA 1.0 design struggles to leverage its wider memory interface as effectively in this API.

Looking at their nearest rivals provides additional context. The W5700X’s average score of 54,828 places it within 1.1% of the NVIDIA GeForce RTX 4080 (54,247) and RTX 4080 SUPER (54,209), while also trailing the AMD Radeon RX 6750 GRE 12 GB (55,698) by 1.6% and the AMD Radeon 8060S (55,757) by 1.7%. The RX 6550M’s average of 46,702 sits 0.2% above the Intel Arc A530M (46,614) and AMD Radeon RX 5600M (46,601), and 1.4% above the NVIDIA RTX A2000 (46,043). These proximity scores suggest that the W5700X competes at the high-end desktop tier, while the RX 6550M holds its own in the midrange mobile segment.

The Verdict

The data supports a straightforward recommendation based on workload and form factor. For users who need maximum compute throughput in OpenCL and can accommodate a quad-slot, 305 mm card with a 205 W TDP, the W5700X offers a modest 3% advantage in that specific API. Its 16 GB memory capacity and 448.0 GB/s bandwidth make it better suited for large datasets and memory-intensive tasks, even if the benchmark scores don’t reflect a huge performance lead.

However, for Vulkan-based applications and workloads, the RX 6550M is the clear winner, outperforming the W5700X by 11.1%. Its ray tracing support, DirectX 12 Ultimate compliance, and dramatically lower power draw of 80 W make it a more future-proof choice for modern graphics APIs. The mobile chip’s higher clocks (2840 MHz boost vs. 2040 MHz) and newer RDNA 2.0 architecture appear to deliver tangible benefits in low-level API scenarios.

The W5700X is end-of-life, released on December 10, 2019, with a launch MSRP of 999 USD. The RX 6550M is active, released on January 3, 2023, and follows the Polaris Mobile as its predecessor. For a builder assembling a new system today, the RX 6550M’s active production status and architectural advantages outweigh the W5700X’s memory and compute resource advantages, unless the specific OpenCL performance and 16 GB capacity are non-negotiable requirements.

Specification Differences

The two cards diverge on nearly every major specification field. The W5700X uses the Navi 10 chip on RDNA 1.0 at 7 nm, while the RX 6550M uses Navi 24 on RDNA 2.0 at 6 nm. Transistor counts are 10,300 million versus 5,400 million, with die sizes of 251 mm² and 107 mm² respectively. Clock speeds favor the RX 6550M: base 2000 MHz vs. 1243 MHz, boost 2840 MHz vs. 2040 MHz, with the mobile card also specifying a game clock of 2560 MHz.

Memory configuration shows the W5700X’s strength: 16 GB GDDR6 on a 256-bit bus at 1750 MHz (14 Gbps effective) delivering 448.0 GB/s, versus 4 GB GDDR6 on a 64-bit bus at 2250 MHz (18 Gbps effective) for 144.0 GB/s. Shading units are 2,560 vs. 1,024, TMUs are 160 vs. 64, and ROPs are 64 vs. 32. The RX 6550M uniquely has 16 ray tracing cores. Pixel rate is 130.6 GPixel/s for the W5700X versus 90.88 GPixel/s for the RX 6550M, and texture rate is 326.4 GTexel/s versus 181.8 GTexel/s.

Power and physical characteristics differ completely. The W5700X has a 205 W TDP, quad-slot width, 305 mm length, and uses an Apple MPX bus interface. The RX 6550M has an 80 W TDP, IGP slot width, no power connectors, and uses PCIe 4.0 x4. Display outputs are 1x HDMI 2.0b plus 4x Thunderbolt for the W5700X, while the RX 6550M is marked as portable device dependent. DirectX support is 12 (12_1) for the W5700X and 12 Ultimate (12_2) for the RX 6550M, with both supporting OpenGL 4.6 and Vulkan 1.4.

Where Each One Wins

The W5700X wins in scenarios that demand large memory capacity and high bandwidth. Its 16 GB GDDR6 frame buffer and 448.0 GB/s bandwidth are ideal for workloads like 4K texture-heavy rendering, large compute simulations, or multi-display professional setups — the 4x Thunderbolt outputs suggest a workstation-oriented design. Its 3% OpenCL advantage over the RX 6550M, combined with higher pixel rate (130.6 GPixel/s) and texture rate (326.4 GTexel/s), makes it the choice for compute-heavy tasks that leverage those resources.

The RX 6550M takes the crown in Vulkan-based applications, with an 11.1% lead that reflects its architectural efficiency and higher clock speeds. Its 16 ray tracing cores enable hardware-accelerated ray tracing, a feature entirely missing from the W5700X. The 80 W TDP and IGP form factor make it suitable for portable devices where power consumption and heat are critical constraints. Its DirectX 12 Ultimate support ensures compatibility with the latest gaming and graphics features.

For gaming, the RX 6550M’s Vulkan performance and RT cores give it a clear edge in modern titles that utilize those APIs. For professional visualization and memory-intensive compute, the W5700X’s larger frame buffer and bandwidth win out. The data does not support one card as universally superior — instead, it shows two GPUs optimized for different environments, with the mobile card surprisingly competitive in raw compute despite its much smaller physical footprint.
