AMD Radeon RX 6550M vs AMD Radeon RX 9070 GRE Comparison

Where Each One Wins

The benchmark data splits this comparison cleanly into two very different performance classes. The AMD Radeon RX 9070 GRE is a desktop-focused part built on the Radeon RX 9000 series, while the AMD Radeon RX 6550M is a mobile-oriented GPU from the Radeon RX 6000 series. Their recorded workloads barely overlap, which makes the use-case split unusually stark.

The RX 9070 GRE wins the only shared test category outright. In Geekbench OpenCL, it records a score of 109,309 against the RX 6550M's 42,536, a 157% advantage. That is not a marginal lead; it is a decisive gap that places the two cards in entirely different performance strata. The RX 9070 GRE also has a DirectX 12 benchmark result (3DMark Steel Nomad, 5,424), a test the RX 6550M does not appear in at all.

The RX 6550M, however, has its own exclusive result: Geekbench Vulkan, where it scores 50,867. No comparable Vulkan score exists for the RX 9070 GRE in the recorded data, so the mobile card can claim a win in that specific API workload by default, though the score itself is lower than the RX 9070 GRE's OpenCL figure. The RX 6550M is also the only one of the two with a portable device dependent display output set, reinforcing its intended role in laptops and compact systems.

For desktop gamers and compute-heavy workloads, the RX 9070 GRE is the clear choice. The RX 6550M serves a different audience: those needing a low-power, mobile-friendly GPU with modest memory requirements. The 4 GB memory capacity and 80 W power envelope of the RX 6550M suggest it is built for thin-and-light systems, not high-end desktop towers. The RX 9070 GRE, with its 220 W power draw, dual-slot cooler, and two 8-pin power connectors, is designed for full-size desktop builds.

Architecture Differences

The two GPUs come from different architectural generations and manufacturing processes. The RX 9070 GRE uses the Navi 48 chip on RDNA 4.0 architecture, fabricated on TSMC's 4 nm process. The RX 6550M uses the Navi 24 chip on RDNA 2.0 architecture, built on TSMC's 6 nm process. The node difference is significant: 4 nm versus 6 nm, and the transistor counts reflect the scale gap. The RX 9070 GRE packs 53,900 million transistors on a 357 mm² die, while the RX 6550M has 5,400 million transistors on a 107 mm² die. Transistor density tells the same story: 151.0 million transistors per square millimeter for the RX 9070 GRE, versus 50.5 million for the RX 6550M.

Compute resources differ massively. The RX 9070 GRE has 3,072 shading units, 192 texture mapping units, 96 raster operation units, and 48 ray tracing cores. The RX 6550M has 1,024 shading units, 64 TMUs, 32 ROPs, and 16 ray tracing cores. The RX 9070 GRE has exactly three times the shading units, three times the TMUs, and three times the ROPs of the RX 6550M. Ray tracing cores follow the same 3:1 ratio.

Clock speeds tell a more nuanced story. The RX 6550M has a higher base clock at 2000 MHz versus 1420 MHz, and a higher boost clock at 2840 MHz versus 2790 MHz. Its game clock is also higher at 2560 MHz versus 2220 MHz. Despite the higher clocks, the RX 6550M cannot overcome its smaller hardware configuration. The RX 9070 GRE delivers 34.28 TFLOPS of FP32 performance, while the RX 6550M manages 5.816 TFLOPS. That is roughly a 5.9x difference in raw floating-point throughput.

Memory architecture is another major divergence. The RX 9070 GRE has 12 GB of GDDR6 on a 192-bit bus, yielding 432.0 GB/s of bandwidth. The RX 6550M has 4 GB of GDDR6 on a 64-bit bus, yielding 144.0 GB/s. Both run memory at 2250 MHz with 18 Gbps effective data rate, but the wider bus of the RX 9070 GRE gives it three times the bandwidth. The RX 9070 GRE also uses a PCIe 5.0 x16 interface, while the RX 6550M uses PCIe 4.0 x4.

Feature support is nearly identical at the API level. Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Neither has tensor cores. The RX 9070 GRE outputs via 1x HDMI 2.1b and 3x DisplayPort 2.1a, while the RX 6550M's outputs are portable device dependent.

Head-to-Head Benchmarks

The only directly comparable benchmark in the database is Geekbench OpenCL, and the result is unambiguous. The RX 9070 GRE scores 109,309, while the RX 6550M scores 42,536. The delta is 157%, meaning the RX 9070 GRE is more than two and a half times faster in this compute workload. For context, the RX 9070 GRE's nearest rivals in the database are the Intel Arc A580 (57,756 average, 0.7% behind), the AMD Radeon RX 5600 OEM (58,085, 1.2% behind), the Intel Arc A570M (58,239, 1.5% behind), and the AMD Radeon RX 6950 XT (58,392, 1.8% behind). The RX 9070 GRE's average benchmark score of 57,367 puts it right in that cluster, and its 87th percentile among all GPUs confirms it sits near the top of the distribution.

The RX 6550M, by contrast, has an average benchmark score of 46,702 and sits at the 85th percentile. Its nearest rivals include the Intel Arc A530M (46,614, 0.2% ahead), the AMD Radeon RX 5600M (46,601, 0.2% ahead), the NVIDIA RTX A2000 (46,043, 1.4% ahead), and the NVIDIA RTX 5880 Ada Generation (45,972, 1.6% ahead). The RX 6550M leads these rivals by very narrow margins, suggesting it is well positioned within its own performance class but nowhere near the RX 9070 GRE's tier.

The RX 9070 GRE also has a 3DMark Steel Nomad DX12 score of 5,424, a result that has no counterpart for the RX 6550M in the recorded data. The RX 6550M's Geekbench Vulkan score of 50,867 similarly lacks a counterpart for the RX 9070 GRE. These exclusive results prevent a full apples-to-apples comparison across every workload, but the one shared test is enough to establish the hierarchy.

The Verdict

The data points to a simple conclusion: the AMD Radeon RX 9070 GRE is the substantially faster GPU. Its 157% lead in the shared OpenCL benchmark is the defining statistic of this comparison. It has three times the shading units, three times the TMUs, three times the ROPs, three times the ray tracing cores, and three times the memory bandwidth of the RX 6550M. Its 34.28 TFLOPS of FP32 performance dwarfs the RX 6550M's 5.816 TFLOPS. The RX 9070 GRE also has more memory (12 GB versus 4 GB), a wider bus (192-bit versus 64-bit), and a newer architecture (RDNA 4.0 versus RDNA 2.0).

The RX 6550M is not without merit. Its higher clock speeds (2000 MHz base, 2840 MHz boost, 2560 MHz game) show that AMD tuned it for efficiency within a mobile power envelope. Its 80 W TDP and lack of external power connectors make it suitable for portable systems. Its Geekbench Vulkan score of 50,867, while lower than the RX 9070 GRE's OpenCL score, demonstrates it can handle compute workloads reasonably well for its class. Its narrow leads over rivals like the Intel Arc A530M and AMD Radeon RX 5600M show it competes effectively in the mobile segment.

Who should pick which? Desktop users with room for a dual-slot, 220 W card should choose the RX 9070 GRE. Its launch MSRP is 549 USD. It delivers top-tier performance, ranking at the 87th percentile among all GPUs, and its 12 GB memory capacity is suited for modern titles and compute tasks. The RX 6550M is for portable systems where power draw and physical size matter more than raw throughput. Its 85th percentile ranking is respectable, but it sits in a different performance class entirely. The recorded data gives no scenario where the RX 6550M outperforms the RX 9070 GRE in a shared workload.
