AMD Instinct MI300X vs NVIDIA GeForce RTX 5050 Mobile Comparison

Head-to-Head Benchmarks

The only directly comparable benchmark between these two accelerators is the Geekbench OpenCL test, and the result is decisive. The AMD Instinct MI300X scores 317,994, while the NVIDIA GeForce RTX 5050 Mobile scores 84,171. That gives the AMD part a 277.8% advantage, meaning it delivers roughly 3.8 times the raw OpenCL performance of the mobile NVIDIA chip.

This gap is not subtle. The MI300X sits at the 100th percentile of all GPUs in the database, meaning no recorded GPU scores higher in aggregate benchmarks. Its average benchmark score is 317,994. The RTX 5050 Mobile, by contrast, sits at the 83rd percentile with an average score of 43,268, a figure pulled down by its second benchmark result, the 3DMark Steel Nomad DX12 test, where it scores 2,365. The MI300X has no recorded 3DMark result, so the database comparison relies on the shared OpenCL workload.

Looking at the MI300X's nearest rivals puts its OpenCL score into context. It trails the NVIDIA H200 NVL, which scores 334,891, by 5%. It trails the NVIDIA B200, which scores 345,482, by 8%. Against the NVIDIA L40S at 295,763, the MI300X is ahead by 7.5%. Against the NVIDIA RTX 6000 Ada Generation at 287,237, it leads by 10.7%. So the MI300X is competitive with NVIDIA's top data center parts, sometimes ahead, sometimes behind, but always in the same performance tier.

The RTX 5050 Mobile's nearest rivals tell a different story. Its average score of 43,268 is essentially identical to the NVIDIA Quadro M6000 24 GB at 43,262, a 0% delta. It trails the NVIDIA Quadro M6000 by 0.1%, which scores 43,301. It leads the NVIDIA GeForce RTX 4070 SUPER by 0.1%, which scores 43,223. It trails the NVIDIA GeForce RTX 4090 Mobile by 0.9%, which scores 43,667. The mobile chip's average performance is therefore indistinguishable from desktop workstation cards from an older generation, and it lands within a narrow band around the 43,000 to 43,700 score range.

The 3DMark Steel Nomad DX12 result of 2,365 is the only gaming-oriented measurement available for the RTX 5050 Mobile. The MI300X has no equivalent entry, and its API support is listed as N/A for DirectX, OpenGL, and Vulkan. That means the MI300X cannot run the same DirectX 12 workload at all, which is an architectural limitation rather than a performance deficit. The RTX 5050 Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so it is the only one of the two that can execute graphics workloads in those APIs.

The Verdict

The data separates these two products by intended role, not just by performance. The AMD Instinct MI300X is a data center accelerator with no display outputs, no graphics API support, and a 277.8% OpenCL lead over the RTX 5050 Mobile. The NVIDIA GeForce RTX 5050 Mobile is a laptop GPU with full graphics API support, portable-device-dependent display outputs, and a 3DMark Steel Nomad score of 2,365 that the MI300X cannot attempt.

The MI300X is the clear winner in raw compute. Its 317,994 OpenCL score places it at the 100th percentile, and its nearest rivals are NVIDIA's H200 NVL, B200, L40S, and RTX 6000 Ada Generation, all data center or professional workstation parts. The RTX 5050 Mobile's nearest rivals, by contrast, are the Quadro M6000 24 GB, the Quadro M6000, the RTX 4070 SUPER, and the RTX 4090 Mobile. The closest of these, the RTX 4090 Mobile, is only 0.9% faster on average. That places the 5050 Mobile firmly in laptop-class performance territory.

The RTX 5050 Mobile wins in every category related to graphics output and consumer software compatibility. It has 32 ROPs, a 48.00 GPixel/s pixel rate, 20 ray tracing cores, 80 tensor cores, and a 12 Ultimate (12_2) DirectX feature level. The MI300X has 0 ROPs, a 0 MPixel/s pixel rate, no ray tracing cores, no tensor core count listed, and no API support. For any workload that requires rasterization, ray tracing, or a display connection, the RTX 5050 Mobile is the only functional option in this comparison.

The verdict depends entirely on workload. For compute-heavy OpenCL tasks, high-performance computing, or AI training and inference, the MI300X is the superior part by a wide margin. For gaming, graphics rendering, or any portable use case, the RTX 5050 Mobile is the only viable choice. The two products do not compete for the same buyer.

Where Each One Wins

The AMD Instinct MI300X wins in raw compute throughput. Its 81.72 TFLOPS FP32 and 81.72 TFLOPS FP16 (1:1) figures dwarf the RTX 5050 Mobile's 7.680 TFLOPS in both formats. The MI300X also delivers 2,553.6 GTexel/s texture rate versus 120.0 GTexel/s for the mobile chip. Memory bandwidth is another decisive win: 5.32 TB/s against 384.0 GB/s, a difference enabled by the HBM3 memory type with an 8192-bit bus, versus GDDR7 on a 128-bit bus. The MI300X has 192 GB of memory versus 8 GB. The MI300X uses 19456 shading units, 1216 TMUs, and no ROPs; the RTX 5050 Mobile uses 2560 shading units, 80 TMUs, and 32 ROPs.

The NVIDIA GeForce RTX 5050 Mobile wins in graphics-specific capabilities. Its 48.00 GPixel/s pixel rate is a real number, while the MI300X records 0 MPixel/s. The RTX 5050 Mobile has 20 ray tracing cores and 80 tensor cores; the MI300X lists neither. The mobile chip supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the MI300X lists N/A for all three. The RTX 5050 Mobile also has display outputs described as portable device dependent, while the MI300X has no outputs at all. In the 3DMark Steel Nomad DX12 benchmark, the RTX 5050 Mobile scores 2,365; the MI300X has no score in that test.

Power consumption is another differentiator. The RTX 5050 Mobile has a 50 W TDP and is classified as an IGP. The MI300X has a 750 W TDP and is an OAM Module. The MI300X requires a 1150 W suggested PSU, while the RTX 5050 Mobile has no suggested PSU listed, reflecting its mobile integration. Neither product uses external power connectors.

Memory capacity and bandwidth strongly favor the MI300X. The 192 GB HBM3 pool with 5.32 TB/s bandwidth is an order of magnitude beyond the RTX 5050 Mobile's 8 GB GDDR7 with 384.0 GB/s. The MI300X's memory clock is listed as 1300 MHz with 5.2 Gbps effective, while the RTX 5050 Mobile runs at 1500 MHz with 24 Gbps effective. The effective data rate per pin is much higher on the NVIDIA part, but the MI300X's 8192-bit bus overwhelms that advantage.
