AMD Radeon RX 5500M vs AMD Radeon RX 9070 XT Comparison

The AMD Radeon RX 9070 XT and AMD Radeon RX 5500M occupy opposite ends of the Radeon spectrum, separated by five years of architectural evolution and a gulf in raw capability. The data shows a decisive victory for the newer card, yet the single benchmark win for the older mobile part reveals an interesting quirk. This analysis dissects the head-to-head results, architectural chasm, and the specific workloads where each card retains a claim to relevance.

Head-to-Head Benchmarks

The head-to-head results are overwhelmingly one-sided. Across nine benchmark tests, the AMD Radeon RX 9070 XT claims eight wins, while the AMD Radeon RX 5500M manages a single, unexpected victory. The magnitude of the RX 9070 XT’s triumphs is staggering, particularly in legacy DirectX and compute workloads.

In Passmark DirectX 11, the RX 9070 XT scores 292 against the RX 5500M’s 35, a delta of 734.3%. This is the largest percentage gap in the entire comparison, underscoring how far the newer architecture has come in handling traditional rasterization APIs. Similarly, in Passmark GPU Compute, the RX 9070 XT posts 15,864 points versus 2,316, a 585% advantage. This reflects a fundamental difference in raw shader throughput and memory bandwidth.

The Passmark G3D test, a general indicator of 3D rendering performance, shows the RX 9070 XT at 26,795 points compared to the RX 5500M’s 5,848, a 358.2% lead. This is not a marginal improvement; it represents a generational leap that places the two cards in entirely different performance tiers. Even in DirectX 10, the older API, the RX 9070 XT leads by 294.9% (154 vs. 39), and in DirectX 9, it leads by 253% (353 vs. 100).

The 2D performance gap, while smaller in absolute terms, is still pronounced. The RX 9070 XT achieves a Passmark G2D score of 1,328 versus 414, a 220.8% difference. This suggests faster memory clocks and a more efficient memory subsystem.

The Vulkan results are closer in percentage terms but still decisive. The RX 9070 XT scores 65,879 against the RX 5500M’s 35,693, a 84.6% lead. This is notable because Vulkan is a modern, low-overhead API that tends to scale well across architectures; the fact that the newer card still nearly doubles the score highlights its superior compute and geometry throughput.

The sole win for the RX 5500M comes in Geekbench OpenCL, where it scores 38,725 versus the RX 9070 XT’s 17,428, a delta of -55% for the newer card. This is a significant anomaly. It suggests that the OpenCL workload in this specific test may favor the RX 5500M’s driver optimizations or its particular compute unit configuration, despite the RX 9070 XT having vastly more shading units and higher clock speeds.

Architecture Differences

The architectural divide between these two GPUs is as wide as the performance gap. The RX 9070 XT is built on the RDNA 4.0 architecture, utilizing the Navi 48 chip, while the RX 5500M uses the older RDNA 1.0 architecture with the Navi 14 chip. This represents a two-generation leap in design philosophy.

The manufacturing process is a critical differentiator. The RX 9070 XT is fabricated on a 4 nm process at TSMC, while the RX 5500M uses a 7 nm process. This allows the newer chip to pack 53,900 million transistors into a 357 mm² die, achieving a transistor density of 151.0M / mm². In contrast, the RX 5500M has only 6,400 million transistors on a 158 mm² die, with a density of 40.5M / mm². The RX 9070 XT has over eight times the transistor count, enabling far more complex execution units.

Core configs reflect this disparity. The RX 9070 XT features 4,096 shading units, 256 TMUs, and 128 ROPs, whereas the RX 5500M has 1,408 shading units, 88 TMUs, and 32 ROPs. The newer card also introduces 64 dedicated RT cores, a feature entirely absent from the RX 5500M, which lists no RT cores. This makes the RX 9070 XT capable of hardware-accelerated ray tracing, a major feature gap.

Clock speeds and memory systems further separate the two. The RX 9070 XT boosts to 2970 MHz with a game clock of 2400 MHz, while the RX 5500M boosts to a much lower 1645 MHz. Memory bandwidth is a stark contrast: the RX 9070 XT has 16 GB of GDDR6 on a 256-bit bus, delivering 644.6 GB/s, while the RX 5500M has 4 GB of GDDR6 on a 128-bit bus, yielding only 224.0 GB/s. The RX 9070 XT also supports PCIe 5.0 x16, while the RX 5500M is limited to PCIe 4.0 x8.

Power and connectivity also differ dramatically. The RX 9070 XT has a TDP of 304 W and requires 2x 8-pin power connectors with a suggested 700 W PSU, while the RX 5500M has a TDP of 85 W and uses no external power connectors. The RX 9070 XT offers modern display outputs (1x HDMI 2.1b, 3x DisplayPort 2.1a), whereas the RX 5500M is listed as "Portable Device Dependent." The RX 9070 XT supports DirectX 12 Ultimate (12_2), while the RX 5500M is limited to DirectX 12 (12_1).

The Verdict

The benchmark data is unambiguous. The AMD Radeon RX 9070 XT is the superior GPU in almost every measurable way. It delivers colossal wins in DirectX 9, 10, 11, and 12 tests, as well as in 3D and compute workloads, with deltas ranging from 84.6% to 734.3%. Its architecture is newer, denser, and more feature-rich, with dedicated ray tracing cores, double the memory capacity, and nearly three times the bandwidth.

The RX 9070 XT’s percentile ranking of 55 against all GPUs, despite its massive raw performance, indicates that its average benchmark score is skewed by the anomalous OpenCL result. Its average benchmark score of 13,543 is nearly identical to the RX 5500M’s 13,356, which is a statistical artifact of that single test. In reality, the RX 9070 XT is in a different league.

The RX 5500M’s only claim to fame is its Geekbench OpenCL score, where it leads by 55%. This is a niche victory, likely tied to specific driver or workload characteristics, and it does not translate to any other tested metric. For any modern gaming or compute task, the RX 9070 XT is the clear choice, provided the system can support its 304 W power draw and dual-slot footprint.

Where Each One Wins

The AMD Radeon RX 9070 XT is the definitive winner in nearly all scenarios. It dominates in legacy DirectX performance, taking massive leads in DirectX 9 (253%), DirectX 10 (294.9%), DirectX 11 (734.3%), and DirectX 12 (178.6%). Its 3D rendering capability is unmatched, as shown by a 358.2% lead in Passmark G3D. For compute-heavy tasks, it leads by 585% in Passmark GPU Compute. Its Vulkan performance is also superior, with an 84.6% advantage. The RX 9070 XT is the only choice for modern gaming, ray tracing workloads, and high-resolution texture rendering, given its 16 GB memory pool and 644.6 GB/s bandwidth. Its 2D performance is also superior, with a 220.8% lead in Passmark G2D.

The AMD Radeon RX 5500M has exactly one niche where it wins: the Geekbench OpenCL benchmark. The data shows it scores 38,725 points, which is 55% higher than the RX 9070 XT. This is a curious result, given the RX 9070 XT’s vastly superior specifications, but it suggests that in specific OpenCL compute tasks, the older card’s driver stack or compute unit scheduling may be more efficient. Outside of this single test, the RX 5500M is consistently and dramatically outperformed. Its only other advantage is practical: with an 85 W TDP and no external power connectors, it is suitable for portable devices, whereas the RX 9070 XT requires a substantial power supply and dual-slot chassis. For any user prioritizing raw performance, the RX 9070 XT is the overwhelming victor.
