AMD Instinct MI300A vs NVIDIA GeForce RTX 4050 Mobile Comparison

Head-to-Head Benchmarks

The recorded data for the AMD Instinct MI300A contains no benchmark scores, while the NVIDIA GeForce RTX 4050 Mobile has a full set of measurements. The MI300A shows an average benchmark score of 0 and a percentile ranking of 50 among all GPUs, but with no actual test results in the database, direct numerical comparisons are impossible. The RTX 4050 Mobile, by contrast, posts an average benchmark score of 19049 and sits at the 63rd percentile.

The RTX 4050 Mobile's Geekbench results show 74748 in OpenCL and 75235 in Vulkan. In PassMark testing, the GPU scores 184 in DirectX 9, 130 in DirectX 11, 79 in DirectX 10, and 61 in DirectX 12. Its PassMark G3D score is 14423, while the G2D score reaches 633. The GPU compute test produces a score of 5947.

The nearest rivals for the RTX 4050 Mobile bracket its performance closely. The AMD Radeon RX 6600 scores 19036, a delta of 0.1 percent. The NVIDIA Quadro K6000 also scores 19030, another 0.1 percent delta. The NVIDIA Tesla K20m scores 19089, which places it 0.2 percent higher. The NVIDIA RTX 2000 Ada Generation scores 18954, 0.5 percent lower. These margins are extremely tight, indicating the RTX 4050 Mobile performs within a single percentage point of all four comparable parts.

Architecture Differences

The two accelerators come from different design philosophies. The AMD Instinct MI300A uses the CDNA 3.0 architecture on a chip called Aqua Vanjaram, built on a 5 nm process at TSMC. The NVIDIA GeForce RTX 4050 Mobile uses the Ada Lovelace architecture on the AD107 chip, also fabricated on a 5 nm process at TSMC. Both share the same process node, but their scale diverges sharply.

The MI300A packs 153,000 million transistors onto a die of 1017 mm², yielding a transistor density of 150.4 million per mm². The RTX 4050 Mobile contains 18,900 million transistors on a 159 mm² die, for a density of 118.9 million per mm². The MI300A is a massive compute accelerator in an OAM Module form factor, while the RTX 4050 Mobile is an integrated graphics processor for laptops.

Memory configurations could hardly differ more. The MI300A carries 128 GB of HBM3 on an 8192-bit bus, delivering 5.32 TB/s of bandwidth. The RTX 4050 Mobile has 6 GB of GDDR6 on a 96-bit bus, with 192.0 GB/s of bandwidth. The MI300A's memory bandwidth is roughly 27.7 times higher, a direct consequence of its server-oriented HBM implementation versus the mobile GDDR6 design.

The compute resources follow the same pattern. The MI300A has 14592 shading units, 912 texture mapping units, and 0 ROPs. Its pixel rate is recorded as 0 MPixel/s because it has no display outputs. The texture rate reaches 1,915.2 GTexel/s, and FP32 performance is 61.29 TFLOPS. The RTX 4050 Mobile has 2560 shading units, 80 TMUs, and 48 ROPs. It delivers 84.24 GPixel/s, 140.4 GTexel/s, and 8.986 TFLOPS FP32. The MI300A leads in FP32 by a factor of roughly 6.8.

The RTX 4050 Mobile includes dedicated ray tracing cores (20) and tensor cores (80), with FP16 performance at 8.986 TFLOPS (1:1 with FP32). The MI300A lists no RT cores and no tensor cores in the database. The MI300A also reports no DirectX, OpenGL, or Vulkan API support, while the RTX 4050 Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The MI300A uses PCIe 5.0 x16, the RTX 4050 Mobile uses PCIe 4.0 x8.

Power draw reflects their different roles. The MI300A has a TDP of 750 W and a suggested PSU of 1150 W. The RTX 4050 Mobile has a TDP of 50 W, which is 700 W lower. The MI300A has no display outputs, while the RTX 4050 Mobile's outputs are portable device dependent.

The Verdict

The data indicates two products designed for entirely separate workloads. The MI300A is a 750 W OAM module with 128 GB of HBM3, 61.29 TFLOPS FP32, and no display outputs. It targets compute-heavy environments where massive memory bandwidth and raw throughput matter, and it carries no benchmark scores in the database to compare against consumer or workstation GPUs.

The RTX 4050 Mobile is a 50 W integrated laptop GPU with 6 GB of GDDR6, 20 RT cores, 80 tensor cores, and full API support including DirectX 12 Ultimate and Vulkan 1.4. Its benchmark results place it within 0.5 percent of four established GPUs, with the Tesla K20m slightly ahead at 0.2 percent and the RTX 2000 Ada Generation slightly behind at 0.5 percent.

A user needing a mobile GPU for graphics workloads, ray tracing, or general compute with standard API support would select the RTX 4050 Mobile. A user needing extreme memory capacity, raw FP32 throughput, and server-class bandwidth would select the MI300A, provided the workload does not require display outputs or consumer graphics APIs.

Where Each One Wins

The MI300A wins decisively in memory capacity, memory bandwidth, and raw FP32 throughput. Its 128 GB of HBM3 with 5.32 TB/s bandwidth dwarfs the RTX 4050 Mobile's 6 GB at 192.0 GB/s. The 6.8 times FP32 advantage and the 1,915.2 GTexel/s texture rate position it for large-scale compute tasks, though the absence of benchmark scores means no measured verification exists in the database.

The RTX 4050 Mobile wins in every measured benchmark category because it is the only one with recorded results. It also wins on power efficiency. Its 50 W TDP is 700 W lower than the MI300A's 750 W, making it suitable for laptops where the MI300A's OAM Module form factor cannot fit. The RTX 4050 Mobile provides ray tracing cores, tensor cores, display outputs, and full API support, none of which the MI300A offers. The RTX 4050 Mobile's benchmark performance matches its nearest rivals within 0.5 percent, confirming it sits in a competitive performance tier for its class.
