AMD Instinct MI300X vs NVIDIA GeForce RTX 5050 Comparison

Head-to-Head Benchmarks

The recorded data contains a single shared benchmark between the AMD Instinct MI300X and the NVIDIA GeForce RTX 5050: Geekbench OpenCL. The results show a decisive advantage for the AMD part. The MI300X scored 317,994 points, while the RTX 5050 scored 90,334 points. This represents a delta of 252% in favor of the AMD Instinct MI300X. In absolute terms, the MI300X delivers more than three times the OpenCL compute performance of the RTX 5050.

Context from the database's nearest-rival comparisons clarifies the magnitude of this gap. The MI300X sits at the 100th percentile among all GPUs in the database, meaning no recorded graphics processor scores higher. Its average benchmark score of 317,994 places it ahead of the NVIDIA L40S (295,763, a 7.5% delta in favor of the MI300X) and the NVIDIA RTX 6000 Ada Generation (287,237, a 10.7% delta). It trails the NVIDIA H200 NVL (334,891, a 5% deficit) and the NVIDIA B200 (345,482, an 8% deficit). These rivals are all data-center class accelerators, and the MI300X holds its own among them.

The RTX 5050, by contrast, sits at the 66th percentile. Its average benchmark score of 21,035 is closest to the AMD Radeon RX Vega M GL (21,153, a 0.6% delta), the AMD Radeon HD 8970M (21,237, a 1% delta), and the NVIDIA RTX A4000 Mobile (21,379, a 1.6% delta). It leads the AMD Radeon RX 5600 XT (20,713) by 1.6%. These rivals are a mix of mobile and older desktop parts, indicating the RTX 5050's competitive set is entirely different from the MI300X's.

The head-to-head OpenCL result, while the only directly comparable data point, aligns with the broader pattern in the database: the MI300X is a compute accelerator built for maximum throughput, while the RTX 5050 is a consumer-oriented graphics card. The 252% delta in this single test is consistent with the architectural and specification differences recorded for the two products.

Where Each One Wins

The AMD Instinct MI300X wins the only shared benchmark, Geekbench OpenCL, by 252%. This result reflects its enormous compute resources and memory subsystem. The MI300X records 19,456 shading units, 1,216 texture mapping units, and an FP32 throughput of 81.72 TFLOPS. Its FP16 performance is identical at 81.72 TFLOPS with a 1:1 ratio. The RTX 5050, by comparison, has 2,560 shading units, 80 TMUs, and 13.17 TFLOPS in both FP32 and FP16. The MI300X's compute capacity is roughly six times higher in raw shading-unit count and FP32 throughput.

The RTX 5050 wins in areas where the database records no direct MI300X equivalent. It has 20 ray tracing cores and 80 tensor cores, features absent from the MI300X's specifications. It also records pixel rate and rasterization outputs: 82.30 GPixel/s and 32 ROPs. The MI300X records 0 ROPs and 0 MPixel/s, indicating it does not perform traditional rasterization. The RTX 5050 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the MI300X lists N/A for all three APIs. The RTX 5050 provides display outputs (1x HDMI 2.1b, 3x DisplayPort 2.1b), while the MI300X has no outputs.

For graphics workloads, the RTX 5050 is the functional part. Its Passmark DirectX results, while not compared directly to the MI300X, show activity across DirectX 9 (186), DirectX 10 (103), DirectX 11 (150), and DirectX 12 (66). The MI300X cannot run these tests because it lacks graphics APIs and display outputs. The RTX 5050 also records a Passmark G2D score of 1,113, indicating 2D graphics capability.

For compute workloads, the MI300X is the dominant part. Its 192 GB of HBM3 memory with 5.32 TB/s bandwidth dwarfs the RTX 5050's 8 GB GDDR6 at 320.0 GB/s. The memory bus width difference is extreme: 8,192 bits versus 128 bits. These figures explain why the MI300X achieves such a high OpenCL score.

Architecture Differences

The two GPUs come from different architectural lineages. The AMD Instinct MI300X uses the CDNA 3.0 architecture on the Aqua Vanjaram chip, built on a 5 nm process at TSMC. The NVIDIA GeForce RTX 5050 uses the Blackwell 2.0 architecture on the GB207 chip, also built on a 5 nm process at TSMC. Both share the same process node and foundry, but the similarities end there.

The MI300X is a massive chip: 153,000 million transistors on a 1,017 mm² die, yielding a transistor density of 150.4 million transistors per mm². The RTX 5050 is far smaller: 16,900 million transistors on a 149 mm² die, with a density of 113.4 million per mm². The MI300X has roughly nine times the transistor count and a die area nearly seven times larger. The higher density of the MI300X indicates tighter packing of compute units.

Clock speeds differ substantially. The MI300X runs at a base clock of 1,000 MHz and a boost clock of 2,100 MHz. The RTX 5050 runs at 2,317 MHz base and 2,572 MHz boost. The RTX 5050's clocks are more than double the MI300X's base and about 22% higher at boost. Despite lower clocks, the MI300X's massive core count delivers far higher aggregate throughput. Memory clocks also differ: the MI300X uses 1,300 MHz with 5.2 Gbps effective data rate, while the RTX 5050 uses 2,500 MHz with 20 Gbps effective.

Memory architecture is fundamentally different. The MI300X uses HBM3 across an 8,192-bit bus, achieving 5.32 TB/s bandwidth with 192 GB capacity. The RTX 5050 uses GDDR6 across a 128-bit bus, achieving 320.0 GB/s with 8 GB capacity. The MI300X has 16 times the bus width and over 16 times the bandwidth. This memory subsystem is the primary driver of its OpenCL advantage.

Power and physical specifications diverge sharply. The MI300X carries a 750 W TDP, uses an OAM Module slot width, has no power connectors, and requires a suggested 1,150 W PSU. The RTX 5050 has a 130 W TDP, uses a Dual-slot design, takes a single 8-pin connector, and needs a suggested 300 W PSU. The MI300X uses a PCIe 5.0 x16 interface, while the RTX 5050 uses PCIe 5.0 x8. The MI300X has no display outputs; the RTX 5050 has four.

Release timing also differs. The MI300X launched on December 5, 2023, in the Instinct (MIx) generation, succeeding Radeon Instinct. The RTX 5050 launched on June 30, 2025, in the GeForce 50 series, succeeding GeForce 40 and with GeForce 60 listed as its successor. The production status for the RTX 5050 is listed as Active; no status is recorded for the MI300X.

The data indicates that a user requiring graphics output, ray tracing, or consumer API support must choose the RTX 5050. A user requiring maximum compute throughput, massive memory capacity, or data-center-class performance must choose the MI300X. The 252% OpenCL delta is not a close contest; it reflects two products engineered for different workloads. The MI300X is the compute leader by every recorded metric that applies to it. The RTX 5050 is the only one of the two that functions as a graphics card. The RTX 5050's launch MSRP is 249 USD.
