AMD Instinct MI325X vs NVIDIA GeForce RTX 5050 Mobile Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the AMD Instinct MI325X and the NVIDIA GeForce RTX 5050 Mobile. The MI325X has no recorded benchmark scores, a percentile rank of 50 among all GPUs, and an average benchmark score of 0. The RTX 5050 Mobile, by contrast, has two recorded benchmark results: a 3DMark Steel Nomad DX12 score of 2365 and a Geekbench OpenCL score of 84171. Its average benchmark score is 43268, placing it in the 83rd percentile of all GPUs.

The RTX 5050 Mobile’s nearest rivals in the database illustrate its competitive position. The NVIDIA Quadro M6000 24 GB scores 43262, a delta of 0 percent. The NVIDIA Quadro M6000 scores 43301, a delta of -0.1 percent, meaning the RTX 5050 Mobile trails that card by one-tenth of a percent. The NVIDIA GeForce RTX 4070 SUPER scores 43223, a delta of 0.1 percent, so the RTX 5050 Mobile edges it out by one-tenth of a percent. The NVIDIA GeForce RTX 4090 Mobile scores 43667, a delta of -0.9 percent, indicating the RTX 5050 Mobile sits nearly a full percent behind that flagship mobile part.

Since the MI325X lacks any benchmark entries, the database cannot provide a numeric comparison of application performance. The wins count stands at 0 for each product. The data records no scenario where the MI325X delivers a measurable performance advantage in a benchmark test, nor does it record a scenario where the RTX 5050 Mobile outperforms the MI325X in a shared test. The absence of head-to-head data means any performance relationship between these two accelerators must be inferred from their architectural and specification differences rather than from direct measurements.

Architecture Differences

The AMD Instinct MI325X uses the Aqua Vanjaram chip built on the CDNA 3.0 architecture, fabricated on a 5 nm process at TSMC. It belongs to the Instinct (MIx) generation and the broader Instinct product line, with the Radeon Instinct as its predecessor. The NVIDIA GeForce RTX 5050 Mobile uses the GB207 chip built on the Blackwell 2.0 architecture, also fabricated on a 5 nm process at TSMC. It belongs to the GeForce 50-series and the GeForce 50 Mobile generation, with the GeForce 40 Mobile as its predecessor.

The transistor counts differ substantially. The MI325X contains 153,000 million transistors on a die size of 1017 mm², yielding a transistor density of 150.4 million transistors per square millimeter. The RTX 5050 Mobile contains 16,900 million transistors on a die size of 149 mm², yielding a transistor density of 113.4 million transistors per square millimeter. The MI325X therefore packs roughly nine times more transistors onto a die that is nearly seven times larger.

The memory subsystems diverge completely. The MI325X uses 256 GB of HBM3e memory with an 8192-bit bus and bandwidth of 6.14 TB/s. The RTX 5050 Mobile uses 8 GB of GDDR7 memory with a 128-bit bus and bandwidth of 384.0 GB/s. The MI325X’s memory bus width is 64 times wider, and its bandwidth is approximately 16 times higher. The RTX 5050 Mobile’s memory clock runs at 1500 MHz with 24 Gbps effective, while the MI325X’s memory clock runs at 1500 MHz with 6 Gbps effective; the GDDR7 implementation in the NVIDIA part achieves a higher effective data rate per pin.

The compute resources are similarly lopsided. The MI325X has 19,456 shading units, 1,216 texture mapping units, and 0 ROPs. The RTX 5050 Mobile has 2,560 shading units, 80 TMUs, and 32 ROPs. The MI325X has no ray tracing cores and no tensor cores listed, while the RTX 5050 Mobile includes 20 ray tracing cores and 80 tensor cores. The MI325X’s pixel rate is recorded as 0 MPixel/s, and its texture rate is 2,553.6 GTexel/s. The RTX 5050 Mobile’s pixel rate is 48.00 GPixel/s, and its texture rate is 120.0 GTexel/s.

Floating-point throughput follows the same pattern. The MI325X delivers 81.72 TFLOPS of FP32 and 81.72 TFLOPS of FP16 with a 1:1 ratio. The RTX 5050 Mobile delivers 7.680 TFLOPS of FP32 and 7.680 TFLOPS of FP16 with a 1:1 ratio. The MI325X’s FP32 throughput is more than ten times higher. The RTX 5050 Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the MI325X lists N/A for all three APIs, reflecting its server-accelerator orientation with no display outputs.

Where Each One Wins

The RTX 5050 Mobile wins in any scenario involving standard graphics workloads, given its recorded benchmark scores and its support for modern graphics APIs. Its 3DMark Steel Nomad DX12 score of 2365 demonstrates real DirectX 12 gaming performance. Its Geekbench OpenCL score of 84171 indicates general-purpose compute capability that is measurable and competitive with its nearest rivals. The RTX 5050 Mobile also has ray tracing cores and tensor cores, which enable hardware-accelerated ray tracing and AI workloads, though the database records no benchmark numbers for those specific features.

The MI325X wins in raw compute density and memory capacity, based on specification data. Its 81.72 TFLOPS FP32 throughput and 6.14 TB/s memory bandwidth place it in a category of high-bandwidth accelerators intended for large-scale data processing. Its 256 GB HBM3e memory capacity exceeds the RTX 5050 Mobile’s 8 GB by a factor of 32. The MI325X’s 8192-bit memory bus allows data movement at a scale that the RTX 5050 Mobile’s 128-bit bus cannot approach. The MI325X also has a higher boost clock of 2100 MHz versus the RTX 5050 Mobile’s 1500 MHz.

The RTX 5050 Mobile wins in power efficiency and physical form. Its TDP is 50 W, while the MI325X has a TDP of 1000 W. The RTX 5050 Mobile is an IGP, meaning it is integrated into a portable device, while the MI325X is an OAM Module with no display outputs. The RTX 5050 Mobile draws one-twentieth the power and fits into mobile platforms, whereas the MI325X requires a server-style module and a suggested PSU of 1400 W.

The Verdict

The data splits clearly by use case. The NVIDIA GeForce RTX 5050 Mobile is the only one of the two with any recorded benchmark performance. Its 3DMark Steel Nomad DX12 score of 2365 and Geekbench OpenCL score of 84171 give it a measurable track record, and its 83rd percentile rank places it above the MI325X’s 50th percentile rank in the database’s global distribution. Its nearest rivals, including the Quadro M6000 24 GB, the Quadro M6000, the RTX 4070 SUPER, and the RTX 4090 Mobile, all sit within a 1 percent delta of its average score, indicating that the RTX 5050 Mobile occupies a well-populated performance tier. For any workload that relies on standard graphics APIs, ray tracing, tensor operations, or DirectX 12 Ultimate, the RTX 5050 Mobile is the functional choice.

The AMD Instinct MI325X is a different class of hardware. Its 256 GB HBM3e memory, 8192-bit bus, 6.14 TB/s bandwidth, and 81.72 TFLOPS FP32 throughput position it as a high-bandwidth compute accelerator with no display outputs and no graphics API support. Its 1000 W TDP and OAM Module form factor target server deployments, not portable devices. The RTX 5050 Mobile’s 50 W TDP and IGP form factor target laptops and mobile workstations. The MI325X’s boost clock of 2100 MHz exceeds the RTX 5050 Mobile’s 1500 MHz, and its texture rate of 2,553.6 GTexel/s dwarfs the RTX 5050 Mobile’s 120.0 GTexel/s, but those numbers only matter in workloads that can use them.

The RTX 5050 Mobile should be selected for graphics rendering, gaming, mobile computing, and any application that requires DirectX, OpenGL, or Vulkan support. The MI325X should be selected for large-scale memory-bound compute tasks that require massive bandwidth and capacity, provided the platform can supply 1400 W and accommodate an OAM Module. The database records no direct benchmark comparison, so the choice rests on the architectural fit: one part delivers measurable graphics performance in a power-efficient mobile package, the other delivers extreme compute resources with no graphics functionality.
