AMD Instinct MI300 vs NVIDIA GeForce RTX 5050 Comparison

Head-to-Head Benchmarks

The recorded data for this comparison is one-sided by necessity. The AMD Instinct MI300 has no benchmark entries in the database, meaning its average benchmark score is recorded as 0, and it holds a 50th percentile position among all GPUs. The NVIDIA GeForce RTX 5050, by contrast, has ten individual benchmark results across multiple test suites, an average score of 21,035, and sits at the 66th percentile. This asymmetry shapes the entire analysis: the MI300's performance profile cannot be quantified through the same measurement tools, while the RTX 5050's numbers provide a concrete reference point.

Focusing on the RTX 5050's recorded scores, the data shows a GPU that performs differently depending on the workload. In 3DMark Steel Nomad DX12, it scores 2,502. Geekbench results are notably higher in compute-oriented tests: OpenCL returns 90,334, and Vulkan returns 89,381. These two scores are nearly identical, which indicates consistent behavior across those two API paths. PassMark results tell a more varied story. The DirectX 9 score is 186, DirectX 10 is 103, DirectX 11 is 150, and DirectX 12 is 66. The DirectX 12 score is the lowest of the four PassMark API tests, which suggests the card's performance in that specific legacy suite does not scale the same way as its Geekbench numbers would imply. PassMark G2D (2D graphics) is 1,113, while PassMark G3D (3D graphics) is 17,326. The GPU compute score in PassMark is 9,184, which is roughly half of the G3D score, indicating a significant gap between rasterized 3D throughput and compute throughput in that test.

The RTX 5050's average benchmark score of 21,035 places it in a specific competitive band. Its nearest rivals in the database are all within a narrow percentage range. The AMD Radeon RX Vega M GL averages 21,153, which is 0.6% lower than the RTX 5050's average. The AMD Radeon HD 8970M averages 21,237, 1% lower. The NVIDIA RTX A4000 Mobile averages 21,379, 1.6% lower. The AMD Radeon RX 5600 XT averages 20,713, which is 1.6% higher than the RTX 5050. This means the RTX 5050 sits in the middle of a tight cluster; the largest recorded performance gap to any of these four rivals is just 1.6%. That is a narrow margin, and it implies that in average benchmark terms, none of these cards has a decisive advantage over the others.

The MI300's lack of benchmark data means there are no head-to-head test results to walk through. The database records zero wins for the MI300 and zero wins for the RTX 5050 in direct comparisons, simply because no such comparisons exist. The MI300's average benchmark score of 0 is not a measured performance level; it is a placeholder for missing data. The percentile ranking of 50 for the MI300, while the RTX 5050 sits at 66, should be read with that caveat. The database does not support any claim that the MI300 is slower; it only supports the statement that no benchmark scores are recorded for it.

The Verdict

From the available data, the RTX 5050 is the only one of the two with measurable benchmark performance. Its 66th percentile ranking and average score of 21,035 give it a defined position in the database, and its nearest rivals confirm that it performs in line with cards like the RX 5600 XT and RTX A4000 Mobile, all within roughly 1.6% of each other. The MI300, with no recorded benchmarks and a 50th percentile default, cannot be placed on the same scale. Any verdict that treats the two as comparable based on numbers alone is unsupported.

The MI300's role in the database is defined by its specifications, not its test results. It is an accelerator with 128 GB of HBM3 memory, 14,080 shading units, and a 600 W TDP, built for a different class of workload than a desktop graphics card. The RTX 5050 is a GeForce 50-series card with 8 GB of GDDR6, 2,560 shading units, and a 130 W TDP. These are not competing products in the conventional sense; the data confirms that they occupy separate categories. The RTX 5050 has an active production status and a successor listed (GeForce 60), while the MI300 has no production status recorded. The RTX 5050 also has a launch MSRP of 249 USD, which is a single data point that does not factor into performance analysis.

For a buyer or analyst looking at benchmark scores, the RTX 5050 is the only option with recorded results. It delivers a consistent average score, and its individual test results show strengths in Geekbench compute workloads. The MI300 cannot be recommended or dismissed on benchmark grounds, because no benchmark data exists. The database does not provide enough information to state which card wins in any test, because only one card was tested.

Where Each One Wins

Based strictly on recorded data, the RTX 5050 wins every measurable category, because it is the only card with measurements. Its Geekbench OpenCL score of 90,334 and Vulkan score of 89,381 are its two highest recorded results, indicating that compute-heavy API workloads are where it performs best relative to its own other scores. The PassMark G3D score of 17,326 is the highest among the PassMark suite, which shows that 3D rendering in that test is stronger than DirectX 12 (66) or DirectX 11 (150) specifically. The PassMark GPU compute score of 9,184 is lower than G3D, which indicates that compute tasks in that suite do not reach the same level as the 3D test.

The MI300 has no wins in the database because no results are recorded. Its specifications, however, suggest capabilities that the RTX 5050 does not have. The MI300 has 128 GB of memory versus 8 GB, a 8192-bit memory bus versus 128-bit, and 5.32 TB/s of bandwidth versus 320.0 GB/s. Those are massive differences in memory capacity and throughput, but they are specification differences, not benchmark wins. The MI300's texture rate of 1,496.0 GTexel/s is over seven times the RTX 5050's 205.8 GTexel/s, and its FP32 throughput of 47.87 TFLOPS is over three times the RTX 5050's 13.17 TFLOPS. Again, these are raw numbers from the specification sheet, not validated by any benchmark run in the database.

The RTX 5050 wins in areas where the MI300 has no capability at all. The MI300 has no display outputs, while the RTX 5050 has 1x HDMI 2.1b and 3x DisplayPort 2.1b. The MI300's API support is listed as N/A for DirectX, OpenGL, and Vulkan, while the RTX 5050 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 5050 also has 20 ray tracing cores and 80 tensor cores, features that are not listed for the MI300. For any workload that requires a display, ray tracing, or conventional graphics APIs, the RTX 5050 is the only one of the two that can function at all.

Architecture Differences

The MI300 uses the Aqua Vanjaram chip based on CDNA 3.0 architecture, built on a 5 nm process at TSMC. The RTX 5050 uses the GB207 chip based on Blackwell 2.0 architecture, also on a 5 nm process at TSMC. Both are manufactured at TSMC, but the architectural goals are different. CDNA 3.0 is designed for compute acceleration, while Blackwell 2.0 targets graphics rendering with additional features.

The transistor counts differ substantially. The MI300 has 153,000 million transistors on a 1017 mm² die, giving a transistor density of 150.4 million per mm². The RTX 5050 has 16,900 million transistors on a 149 mm² die, with a density of 113.4 million per mm². The MI300's die is roughly 6.8 times larger, and its transistor count is roughly 9 times higher. The density difference indicates that the MI300 packs transistors more tightly, but the architectural distribution is not directly comparable.

The MI300 has no ray tracing cores and no tensor cores listed, while the RTX 5050 has 20 ray tracing cores and 80 tensor cores. The MI300 has 14,080 shading units, 880 texture mapping units, and 0 raster output units. The RTX 5050 has 2,560 shading units, 80 texture mapping units, and 32 raster output units. The MI300's pixel rate is recorded as 0 MPixel/s, while the RTX 5050 has a pixel rate of 82.30 GPixel/s. This reflects the MI300's lack of traditional rasterization output, consistent with its compute-focused design.

Memory architecture is another major divergence. The MI300 uses HBM3 with a 8192-bit bus and 5.32 TB/s bandwidth. The RTX 5050 uses GDDR6 with a 128-bit bus and 320.0 GB/s bandwidth. The MI300's memory bandwidth is over 16 times higher, which is a direct consequence of its wide bus and HBM stacking. The RTX 5050's dual-slot design and 1x 8-pin power connector contrast with the MI300's 2x 8-pin connectors and no slot width recorded.

Specification Differences

The two cards differ in nearly every recorded specification field. The MI300 uses CDNA 3.0 architecture, while the RTX 5050 uses Blackwell 2.0.
