AMD Radeon Pro 5500M vs AMD Radeon RX 6500 XT Comparison

The AMD Radeon RX 6500 XT and the AMD Radeon Pro 5500M are both end-of-life AMD GPUs, yet they target very different corners of the market. The data reveals a decisive performance hierarchy, with the RX 6500 XT winning all nine head-to-head benchmarks against the Pro 5500M. However, a closer look at their architecture and specifications reveals that the Pro 5500M is not without its own distinct advantages, making the choice between them far more nuanced than a simple score comparison.

Head-to-Head Benchmarks

The benchmark results are unambiguous: the RX 6500 XT dominates the Pro 5500M in every single recorded test. The largest margin is in the Passmark DirectX 11 test, where the RX 6500 XT scores 90 versus the Pro 5500M's 42, a massive 114.3% advantage. This near-doubling of performance in a legacy API suggests the RX 6500 XT's architecture handles older workloads with significantly greater efficiency.

The trend continues across other synthetic tests. In the Geekbench Vulkan test, the RX 6500 XT scores 54,724, which is 55.8% higher than the Pro 5500M's 35,134. Similarly, the Geekbench OpenCL test shows a 55.3% lead for the RX 6500 XT (48,289 vs. 31,088). These consistent double-digit percentage leads across different API and compute benchmarks indicate a fundamental performance gap rather than a workload-specific anomaly.

The gap narrows in some tests but remains firmly in the RX 6500 XT's favor. In the Passmark DirectX 9 test, the lead shrinks to 12.5% (108 vs. 96), and in DirectX 12, it is a 31% advantage (38 vs. 29). The Passmark G2D test, which measures 2D graphics performance, shows a 25.8% lead for the RX 6500 XT (815 vs. 648). Even in compute-heavy tasks like Passmark GPU Compute, the RX 6500 XT is ahead by 37.5% (4,456 vs. 3,240). The overall Passmark G3D score reinforces this, with the RX 6500 XT achieving 9,608 against the Pro 5500M's 6,732, a 42.7% difference.

Where Each One Wins

Based on the benchmark data, the RX 6500 XT is the clear winner for almost every use case. Its victories in DirectX 11 and DirectX 12 benchmarks suggest it is better suited for gaming, particularly with older or more modern titles respectively. Its substantial leads in OpenCL and Vulkan compute benchmarks also make it the stronger choice for general-purpose GPU computing tasks that leverage these APIs.

The Pro 5500M, while losing all benchmarks, does possess a specification that points to a specific advantage: it has 8 GB of memory compared to the RX 6500 XT's 4 GB. While the benchmark scores do not show a scenario where this capacity is the deciding factor, the data implies that for workloads that require large frame buffers—such as high-resolution texture sets or complex professional visualizations—the Pro 5500M could offer a smoother experience despite its lower raw compute power. Its lower TDP of 85 W versus the RX 6500 XT's 107 W also suggests it is a more power-efficient option, which is critical for mobile platforms where the Pro 5500M, being a "Pro" mobile chip, is likely to be found.

FAQ

Q: How do these GPUs compare to other mid-range cards?

A: The RX 6500 XT's average benchmark score of 11,842 puts it within 1% of the NVIDIA GeForce GTX 1080 (11,960) and 1.4% ahead of the GTX 1660 (11,680). The Pro 5500M's average score of 11,528 is 1.3% behind the GTX 1660 and 0.8% behind the AMD Radeon RX 7800 XT.

Q: Is the Pro 5500M competitive in any specific API?

A: Its closest performance in the head-to-head is in the Passmark DirectX 9 test, where it trails the RX 6500 XT by only 12.5% (96 vs. 108). This suggests it handles legacy DirectX 9 workloads comparatively better than other modern APIs.

Q: Which card has a higher memory capacity?

A: The AMD Radeon Pro 5500M has 8 GB of GDDR6 memory, which is double the 4 GB found on the AMD Radeon RX 6500 XT.

Q: What is the performance difference in DirectX 11?

A: The RX 6500 XT is over twice as fast. Its Passmark DirectX 11 score is 90, compared to 42 for the Pro 5500M, representing a 114.3% advantage.

Specification Differences

The two cards diverge significantly on core specifications. The RX 6500 XT features 1024 shading units, 64 texture mapping units (TMUs), and 32 render output units (ROPs). In contrast, the Pro 5500M has more of each of these: 1536 shading units, 96 TMUs, and 32 ROPs. Despite having fewer cores, the RX 6500 XT achieves higher performance due to its much higher clock speeds. The RX 6500 XT has a base clock of 2310 MHz and a boost clock of 2815 MHz, while the Pro 5500M is significantly slower, with a 1000 MHz base and 1450 MHz boost.

Memory configurations also differ. The RX 6500 XT uses a 64-bit memory bus with 4 GB of GDDR6, resulting in a bandwidth of 143.9 GB/s. The Pro 5500M uses a wider 128-bit bus with 8 GB of GDDR6, giving it a higher bandwidth of 192.0 GB/s. The power profiles are distinct as well, with the RX 6500 XT rated at 107 W TDP and requiring a 1x 6-pin power connector, while the Pro 5500M is rated at 85 W TDP and requires no power connectors. The RX 6500 XT is a dual-slot card with a PCIe 4.0 x4 interface, whereas the Pro 5500M has a PCIe 4.0 x8 interface.

Architecture Differences

These GPUs represent two different generations of AMD architecture. The RX 6500 XT is built on the RDNA 2.0 architecture, using the Navi 24 chip, while the Pro 5500M uses the older RDNA 1.0 architecture with the Navi 14 chip. This generational leap is reflected in the manufacturing process: the RX 6500 XT uses a more advanced 6 nm process at TSMC, while the Pro 5500M is built on a 7 nm process. The RDNA 2.0 chip also includes dedicated ray tracing cores (16 of them), a feature entirely absent from the RDNA 1.0-based Pro 5500M.

The architectural differences also manifest in feature support. The RX 6500 XT supports DirectX 12 Ultimate (12_2), while the Pro 5500M is limited to DirectX 12 (12_1). The RX 6500 XT's silicon is denser, with 5,400 million transistors on a 107 mm² die (50.5M / mm²), compared to the Pro 5500M's 6,400 million transistors on a larger 158 mm² die (40.5M / mm²). The RX 6500 XT is also a newer product, released on 2022-01-18, whereas the Pro 5500M launched earlier on 2019-11-12, and the RX 6500 XT has a launch MSRP of 199 USD.

The Verdict

The data is clear for gamers and general users: the AMD Radeon RX 6500 XT is the superior performer. Its wins in every benchmark, particularly its 42.7% lead in Passmark G3D and 55.8% lead in Vulkan, make it the definitive choice for gaming and compute tasks that rely on modern APIs. Its RDNA 2.0 architecture and support for DirectX 12 Ultimate ensure it is better equipped for current and future software. Anyone building a system focused on performance should select the RX 6500 XT.

The case for the AMD Radeon Pro 5500M is more specific. Its 8 GB of memory, double that of the RX 6500 XT, and its wider 128-bit memory bus offering 192.0 GB/s of bandwidth, suggest it is better suited for professional workloads that require large datasets or high-resolution buffers. Its lower 85 W TDP also makes it a more efficient option for slim or mobile chassis where power and thermal limits are strict. For users whose primary need is memory capacity and power efficiency over raw compute speed, the Pro 5500M remains a viable, albeit slower, option.
