AMD Instinct MI300X vs NVIDIA GeForce RTX 3050 A Mobile Comparison

Head-to-Head Benchmarks

The recorded database contains a single shared benchmark between the AMD Instinct MI300X and the NVIDIA GeForce RTX 3050 A Mobile: Geekbench OpenCL. In this test, the AMD Instinct MI300X scores 317994 points against 52998 points for the NVIDIA part. The delta is 500%, meaning the AMD accelerator delivers six times the raw compute throughput of the mobile GPU in this workload. This is the only common test in the database, so the comparison rests entirely on this one measurement.

The AMD Instinct MI300X sits in the 100th percentile of all GPUs in the database. Its nearest rivals illustrate the scale of its performance tier. The NVIDIA H200 NVL scores 334891, which is 5% higher than the MI300X. The NVIDIA B200 scores 345482, an 8% advantage. On the other side, the NVIDIA L40S scores 295763, which is 7.5% lower, and the NVIDIA RTX 6000 Ada Generation scores 287237, which is 10.7% lower. The MI300X therefore occupies a position among the very top accelerators, slightly behind the flagship H200 NVL and B200 but comfortably ahead of the L40S and RTX 6000 Ada Generation.

The NVIDIA GeForce RTX 3050 A Mobile, by contrast, sits in the 44th percentile of all GPUs. Its average benchmark score across all recorded tests is 8746, while the MI300X has an average score of 317994 from its single OpenCL result. The mobile GPU's nearest rivals are far less exotic: the NVIDIA GeForce GTX 460 v2 scores 8743 (delta 0%), the NVIDIA Quadro P2200 scores 8686 (0.7% higher), the AMD Radeon R9 M265X scores 8851 (1.2% higher), and the AMD Radeon Pro WX 5100 scores 8863 (1.3% higher). These deltas show the RTX 3050 A Mobile clustering with mid-range desktop and mobile parts from a much older era, not with the accelerator class.

The sheer gap between the two products is unmatched in the database's head-to-head records. The MI300X's OpenCL score is 500% higher, and no other benchmark in the pair's records shows the NVIDIA part winning. The wins tally is 1 for the AMD product and 0 for the NVIDIA product. There is no counterbalancing result that favors the mobile GPU anywhere in the recorded data.

Architecture Differences

The two products come from fundamentally different design philosophies. The AMD Instinct MI300X uses the CDNA 3.0 architecture, built on the Aqua Vanjaram chip, fabricated on a 5 nm process at TSMC. The NVIDIA GeForce RTX 3050 A Mobile uses the Ampere architecture with the GA106 chip, fabricated on an 8 nm process at Samsung. The process node difference alone explains a large portion of the transistor density gap: the MI300X packs 153,000 million transistors into a 1017 mm² die, yielding 150.4 million transistors per square millimeter. The RTX 3050 A Mobile contains 12,000 million transistors on a 276 mm² die, for a density of 43.5 million per square millimeter. That is a 3.5x density advantage for the AMD part, enabled by the more advanced node.

Memory configurations are equally divergent. The MI300X carries 192 GB of HBM3 on an 8192-bit bus, with a bandwidth of 5.32 TB/s. The RTX 3050 A Mobile has 4 GB of GDDR6 on a 128-bit bus, delivering 192.0 GB/s. The bandwidth ratio is roughly 27.7 to 1 in favor of the AMD accelerator. Memory clock rates also differ: the MI300X runs at 1300 MHz with 5.2 Gbps effective, while the RTX 3050 A Mobile runs at 1500 MHz with 12 Gbps effective. The GDDR6 part uses a higher per-pin data rate, but the far wider HBM3 bus overwhelms it in total throughput.

Compute unit counts follow the same pattern. The MI300X has 19456 shading units, 1216 texture mapping units, and no ROPs (0). Its pixel rate is listed as 0 MPixel/s, which reflects its purpose as a compute accelerator without a rasterization output stage. The RTX 3050 A Mobile has 1792 shading units, 56 TMUs, and 32 ROPs, with a pixel rate of 42.98 GPixel/s and a texture rate of 75.21 GTexel/s. The MI300X's texture rate is 2,553.6 GTexel/s, which is roughly 34 times higher. Floating-point throughput shows the same story: the MI300X delivers 81.72 TFLOPS for both FP32 and FP16 (at a 1:1 ratio), while the RTX 3050 A Mobile delivers 4.813 TFLOPS for both FP32 and FP16 (also 1:1). That is a 17x difference in raw FP32 compute.

Feature sets diverge sharply. The RTX 3050 A Mobile includes 14 ray tracing cores and 56 tensor cores, and supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The MI300X lists no ray tracing cores, no tensor cores, and no graphics API support (N/A for DirectX, OpenGL, and Vulkan). It also has no display outputs. The NVIDIA part is a full graphics processor with a complete rendering pipeline; the AMD part is a pure compute accelerator with no display path. The bus interfaces differ as well: the MI300X uses PCIe 5.0 x16, while the RTX 3050 A Mobile uses PCIe 4.0 x8. Power delivery is also on different scales, though the exact figures are recorded only for the AMD part (750 W TDP, 1150 W suggested PSU) and the NVIDIA part (45 W TDP, no suggested PSU listed). The RTX 3050 A Mobile is an IGP form factor with no power connectors; the MI300X is an OAM module with no power connectors listed.

Where Each One Wins

The data provides only one head-to-head test, so the win breakdown is necessarily lopsided. The AMD Instinct MI300X wins the Geekbench OpenCL test outright, and that is the only test where both products have recorded scores. The NVIDIA GeForce RTX 3050 A Mobile has additional benchmark entries in the database that the MI300X does not share: Passmark DirectX 10 (61), DirectX 11 (94), DirectX 12 (55), DirectX 9 (152), G2D (526), G3D (11664), and GPU Compute (4419). These tests measure graphics API performance and 2D/3D rasterization, areas where the MI300X has no recorded capability at all. The MI300X lists no DirectX support, no OpenGL support, no Vulkan support, and no display outputs, so it cannot participate in those workloads.

For compute-heavy tasks, the MI300X is the clear choice. Its OpenCL score of 317994 places it in the top 100th percentile, and its nearest rivals are all enterprise accelerators. The RTX 3050 A Mobile's OpenCL score of 52998 is 500% lower, and its average benchmark score of 8746 is dragged down by its graphics tests. For any application that relies on FP32 or FP16 throughput, large memory capacity, or memory bandwidth, the MI300X dominates. Its 192 GB HBM3 pool and 5.32 TB/s bandwidth target large model inference and training workloads, while its 81.72 TFLOPS FP32 rate provides the compute headroom for dense matrix operations.

The RTX 3050 A Mobile wins in the categories it was designed for, even though those categories are not represented in the shared benchmark set. It has 14 ray tracing cores and 56 tensor cores, which the MI300X lacks entirely. It supports the full DirectX 12 Ultimate feature set, OpenGL 4.6, and Vulkan 1.4, making it a functional graphics adapter for portable devices. Its 42.98 GPixel/s pixel rate and 75.21 GTexel/s texture rate indicate a working rasterization pipeline, and its 4 GB GDDR6 memory is sufficient for frame buffer duties. None of these attributes appear in the MI300X's specification sheet, because the accelerator has no graphics pipeline at all.

The use-case split is therefore clean. The MI300X is for compute acceleration, where it ranks among the top accelerators in the database. The RTX 3050 A Mobile is for graphics rendering and portable deployment, where its 44th percentile standing reflects a mid-tier mobile part. The two products do not compete in the same workloads, and the single shared benchmark confirms that whenever the workload is OpenCL compute, the AMD part wins by a wide margin.

The Verdict

The recorded data points to a simple conclusion. The AMD Instinct MI300X is a compute accelerator in the highest performance tier, with a 100th percentile ranking and an OpenCL score of 317994. Its nearest rivals are the NVIDIA H200 NVL (334891, 5% higher), the NVIDIA B200 (345482, 8% higher), the NVIDIA L40S (295763, 7.5% lower), and the NVIDIA RTX 6000 Ada Generation (287237, 10.7% lower). The NVIDIA GeForce RTX 3050 A Mobile is a mid-range mobile graphics processor, with a 44th percentile ranking and an average score of 8746. Its nearest rivals are the GeForce GTX 460 v2 (8743), the Quadro P2200 (8686), the Radeon R9 M265X (8851), and the Radeon Pro WX 5100 (8863), all within roughly 1.3% of its score.

No benchmark in the database shows the RTX 3050 A Mobile beating the MI300X. The only shared test, Geekbench OpenCL, shows a 500% advantage for the AMD part. The MI300X also leads in every relevant compute specification: 17x more FP32 throughput, 27.7x more memory bandwidth, 16x more memory capacity, and 3.5x higher transistor density. For compute workloads in the database's measurement scope, the MI300X is the clear winner.

The RTX 3050 A Mobile does have its own territory. It is the only one of the two with any graphics API support, any display outputs, any ray tracing cores, or any tensor cores. It also runs at 45 W TDP versus the MI300X's 750 W TDP, making it suitable for portable devices. The MI300X has no graphics capabilities at all, so any workload requiring DirectX, OpenGL, Vulkan, or a display path must use the NVIDIA part. The verdict from the data is straightforward: choose the MI300X for compute acceleration, choose the RTX 3050 A Mobile for graphics rendering, and understand that they are not interchangeable products.
