AMD Radeon 550X vs AMD Radeon 880M Comparison

AMD Radeon 550X and AMD Radeon 880M are GPUs from different eras and market segments, and the benchmark data reflects a decisive generational gap. The 880M, an integrated processor from 2024, utterly dominates the 550X, a 2019 discrete part, in every comparable test, delivering over three times the OpenCL score and over four times the Vulkan score. Despite the 550X having a higher percentile ranking (45th vs 43rd), its average benchmark score of 8918 is only slightly ahead of the 880M's 8436, which is skewed by the 880M's inclusion of low-level synthetic tests. The verdict is clear: for any modern workload, the 880M is the superior choice, while the 550X only holds relevance in legacy systems.

FAQ

Q: Based on the benchmark data, which GPU has the higher Geekbench OpenCL score?

A: The AMD Radeon 880M wins decisively with a score of 31285, compared to the AMD Radeon 550X's 8866. This represents a 71.7% delta in favor of the 880M.

Q: How do the two GPUs compare in their average benchmark scores and overall percentile ranking?

A: The AMD Radeon 550X has a slightly higher average benchmark score of 8918 and a better percentile rank of 45. The AMD Radeon 880M has a lower average score of 8436 and a percentile rank of 43, despite winning the head-to-head tests.

Q: What is the architectural generation gap between the two processors?

A: The AMD Radeon 550X is built on the older GCN 4.0 architecture, part of the Polaris (RX 500X) generation, while the AMD Radeon 880M uses the modern RDNA 3.5 architecture from the Navi III IGP generation.

Q: What are the core differences in memory configuration?

Q: Are there any benchmarks where the AMD Radeon 550X wins?

A: No. In the head-to-head benchmarks provided, the AMD Radeon 880M wins both the Geekbench OpenCL and Geekbench Vulkan tests. The 550X has zero wins in this comparison.

The Verdict

The data is unambiguous: the AMD Radeon 880M is the far more capable GPU. For any user building a new system or seeking modern performance, the 880M is the only rational choice. Its victory in the Vulkan test is particularly stark, scoring 40006 versus the 550X's 8970, a 77.6% difference. This indicates a massive advantage in modern graphics APIs and gaming workloads.

The AMD Radeon 550X, an end-of-life product, is not competitive. While it holds a marginal edge in the aggregate average benchmark score (8918 vs 8436), this is misleading. The 550X's score is based on just two Geekbench tests, while the 880M's average includes several low-level Passmark tests (e.g., 31 in DirectX 10, 32 in DirectX 12) that drag its average down despite its high Geekbench performance. The 550X should only be considered for legacy systems where it is already installed or where specific driver support is required. For everything else, the 880M wins on raw performance, modern feature support, and efficiency.

Head-to-Head Benchmarks

The head-to-head data shows a total dominance by the AMD Radeon 880M, which wins both recorded tests. The most dramatic victory is in the Geekbench Vulkan test. Here, the 880M scores 40006, while the 550X manages only 8970. This is a delta of -77.6% from the perspective of the 550X, meaning the 880M is approximately 4.5 times faster. This is a clear indicator of the architectural leap from GCN 4.0 to RDNA 3.5, which offers far better performance in modern, low-level graphics APIs.

In the Geekbench OpenCL test, the 880M also wins decisively with a score of 31285 against the 550X's 8866. The delta is -71.7%, again in favor of the 880M. While OpenCL is a more general-purpose compute API, the result still shows a massive performance gap. The 550X's compute capabilities, pegged at 1,247.2 GFLOPS FP32, are simply outclassed by the 880M's 4.454 TFLOPS. The 550X has zero wins, while the 880M has two, painting a picture of total superiority in every measurable comparison.

Specification Differences

The specification sheets reveal fundamental differences beyond just performance. The AMD Radeon 880M is built on a 4 nm process at TSMC, a stark contrast to the 550X's 14 nm process at GlobalFoundries. This allows the 880M to pack 34,000 million transistors into a 233 mm² die, resulting in a transistor density of 145.9M / mm², compared to the 550X's 2,200 million transistors on a 103 mm² die (21.4M / mm²). This is a massive efficiency and density advantage for the 880M.

Clock speeds also differ hugely. The 550X has a base clock of 1082 MHz and a boost of 1218 MHz, while the 880M has a much lower base clock of 400 MHz but a much higher boost of 2900 MHz. The 880M also features 768 shading units, 48 TMUs, and 12 RT cores, versus the 550X's 512 shading units, 32 TMUs, and no RT cores. Both have 16 ROPs. The TDP is another major differentiator: the 550X is rated at 50 W, while the 880M is a 15 W IGP. The 880M also supports newer standards, including DirectX 12 Ultimate (12_2) and Vulkan 1.4, whereas the 550X is limited to DirectX 12 (12_0) and Vulkan 1.3.

Architecture Differences

The two GPUs are built on completely different architectural foundations. The AMD Radeon 550X uses the GCN 4.0 architecture on the "Lexa" chip, part of the Polaris (RX 500X) generation. This architecture, released in 2019, lacks dedicated ray tracing hardware. In contrast, the AMD Radeon 880M uses the RDNA 3.5 architecture on the "Strix Point" chip, from the Navi III IGP generation. This modern design includes 12 dedicated RT cores, enabling hardware-accelerated ray tracing, a feature entirely absent on the 550X.

The memory architecture also represents a fundamental difference. The 550X is a discrete GPU with its own 2 GB of GDDR5 memory, providing a fixed 112.0 GB/s of bandwidth. The 880M is an integrated graphics processor (IGP) that relies on System Shared memory, making its bandwidth and capacity dependent on the host system's RAM. This is a crucial distinction for performance scaling. The 880M's FP32 compute throughput of 4.454 TFLOPS is over 3.5 times higher than the 550X's 1,247.2 GFLOPS, a direct result of the newer architecture's efficiency and higher core count.

Where Each One Wins

The AMD Radeon 880M wins in nearly every conceivable scenario. Its dominant performance in both OpenCL and Vulkan makes it the clear choice for modern gaming, content creation, and any GPU-accelerated workload. The presence of 12 RT cores provides hardware ray tracing support, a feature that the 550X cannot offer. With a 15 W TDP and no power connectors, it is also dramatically more power-efficient than the 50 W 550X, making it ideal for thin-and-light laptops and compact systems. The 880M's support for DirectX 12 Ultimate and Vulkan 1.4 also ensures compatibility with future software titles.

The AMD Radeon 550X only "wins" in the narrow context of legacy compatibility. As a discrete card with its own dedicated 2 GB of GDDR5 memory, it offers a fixed memory pool that does not compete with system RAM. This could be a benefit in very old systems with limited RAM, or in scenarios where a user specifically requires the old GCN architecture for driver support in legacy applications. Its dual-slot form factor and standard display outputs (DVI, HDMI 2.0b, DisplayPort 1.4a) make it a plug-and-play option for older desktops. However, these are minor advantages that do not offset the massive performance deficit. In any modern context, the 880M is the definitive winner.
