AMD Instinct MI300 vs NVIDIA GeForce RTX 3050 6 GB Comparison

Head-to-Head Benchmarks

The AMD Instinct MI300 and the NVIDIA GeForce RTX 3050 6 GB occupy vastly different segments of the GPU spectrum, and the benchmark data reflects this divide clearly. The MI300 is a compute-focused accelerator with no display outputs, while the RTX 3050 6 GB is a consumer graphics card with a full suite of display outputs. The recorded data shows zero head-to-head benchmark entries, meaning no direct comparative tests exist in the database. However, the available benchmark scores for the RTX 3050 6 GB and the architectural specifications of the MI300 allow for a meaningful comparison based on recorded measurements.

The RTX 3050 6 GB delivers an average benchmark score of 2329 across its tested workloads. Its nearest rivals in the database include the NVIDIA GeForce GT 640M with an average score of 2335 (a delta of -0.3%), the NVIDIA Quadro P620 at 2339 (delta -0.4%), the Intel HD Graphics 510 at 2305 (delta +1%), and the NVIDIA GeForce GT 550M at 2363 (delta -1.4%). This places the RTX 3050 6 GB in the 15th percentile of all GPUs in the database, indicating that it sits near the lower end of the performance distribution among recorded graphics cards.

The MI300 has no benchmark scores recorded in the database and therefore holds a 50th percentile ranking with an average benchmark score of zero. This absence of data does not indicate poor performance; rather, it reflects the accelerator's positioning outside the consumer benchmark suite used for the RTX 3050 6 GB. The MI300's raw compute figures, however, are recorded and provide a stark contrast. The MI300 achieves 47.87 TFLOPS of FP32 performance, while the RTX 3050 6 GB delivers 6.774 TFLOPS in the same precision. This represents a substantial gap in raw floating-point throughput, with the MI300 delivering roughly seven times the FP32 compute of the RTX 3050 6 GB based on the recorded specifications.

The texture rate data reinforces this divide. The MI300 posts a texture rate of 1,496.0 GTexel/s, whereas the RTX 3050 6 GB manages 105.8 GTexel/s. The MI300's advantage here is approximately 14 times the texture throughput of the RTX 3050 6 GB. Conversely, the pixel rate tells a different story: the MI300 records 0 MPixel/s because it lacks raster output units, while the RTX 3050 6 GB achieves 47.04 GPixel/s. This makes the RTX 3050 6 GB the only one of the two capable of pixel-based rendering, which is essential for traditional graphics workloads.

The memory subsystem further separates the two products. The MI300 carries 128 GB of HBM3 memory across an 8192-bit bus, yielding 5.32 TB/s of bandwidth. The RTX 3050 6 GB has 6 GB of GDDR6 memory on a 96-bit bus, providing 168.0 GB/s. The MI300's bandwidth advantage is roughly 31 times that of the RTX 3050 6 GB, based on the recorded figures. Memory clock rates also differ: the MI300 runs at 1300 MHz (5.2 Gbps effective), while the RTX 3050 6 GB operates at 1750 MHz (14 Gbps effective). The higher effective data rate of the RTX 3050 6 GB's GDDR6 memory does not compensate for the massively wider bus of the MI300's HBM3 stack.

Where Each One Wins

The MI300 wins decisively in compute-heavy scenarios. Its FP32 throughput of 47.87 TFLOPS and FP16 throughput of 47.87 TFLOPS (1:1 ratio) indicate that it is designed for high-precision scientific and AI workloads where massive parallel compute is the primary requirement. The texture rate of 1,496.0 GTexel/s suggests that texturing operations, if they were relevant to its intended use, would proceed at an extremely high rate. The 128 GB HBM3 memory pool with 5.32 TB/s bandwidth makes it suitable for large datasets that need to reside close to the compute units, such as in training large language models or processing massive simulation grids. The MI300's 153,000 million transistors on a 1017 mm² die, built on a 5 nm TSMC process, provide the physical resources for these workloads. The 14,080 shading units and 880 texture mapping units far exceed those of the RTX 3050 6 GB, which has 2,304 shading units and 72 texture mapping units.

The RTX 3050 6 GB wins in every scenario that requires rasterization and display output. Its 32 raster output units deliver 47.04 GPixel/s, enabling actual pixel generation that the MI300 cannot perform at all, given its 0 MPixel/s rate and lack of display outputs. The RTX 3050 6 GB supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the MI300 lists N/A for all three APIs. This makes the RTX 3050 6 GB the only viable option for gaming, desktop graphics, or any application that renders to a screen. The RTX 3050 6 GB also includes 18 ray tracing cores and 72 tensor cores, features that the MI300 does not list. These hardware units enable hardware-accelerated ray tracing and AI-assisted features like DLSS, which are absent from the MI300's specification sheet.

The RTX 3050 6 GB also wins on power efficiency in the traditional sense. Its TDP is 70 W with a suggested power supply of 250 W, while the MI300 draws 600 W and requires a 1000 W power supply. The RTX 3050 6 GB requires no power connectors, drawing entirely from the PCIe slot, whereas the MI300 needs 2x 8-pin connectors. For systems constrained by power delivery or thermal capacity, the RTX 3050 6 GB presents a far less demanding installation profile. The RTX 3050 6 GB measures 242 mm in length, while the MI300 is 267 mm, both fitting in most standard chassis, but the power requirements differ drastically.

Architecture Differences

The architectural split between the MI300 and the RTX 3050 6 GB is fundamental. The MI300 uses AMD's CDNA 3.0 architecture on the Aqua Vanjaram chip, manufactured on a 5 nm TSMC process. The RTX 3050 6 GB uses NVIDIA's Ampere architecture on the GA107 chip, fabricated on an 8 nm Samsung process. The process node difference gives the MI300 a transistor density of 150.4 million transistors per mm², while the RTX 3050 6 GB achieves 43.5 million per mm². The MI300 packs 153,000 million transistors onto a 1017 mm² die, compared to the RTX 3050 6 GB's 8,700 million transistors on a 200 mm² die. This represents a massive difference in both total transistor count and die area, with the MI300's die being more than five times larger and containing over 17 times the transistors.

The memory architecture also diverges completely. The MI300 uses HBM3 memory with an 8192-bit bus width, a configuration optimized for maximum bandwidth at the expense of capacity per stack. The RTX 3050 6 GB uses GDDR6 with a 96-bit bus, a design chosen for cost-effectiveness and adequate bandwidth for consumer workloads. The MI300's memory clock is 1300 MHz (5.2 Gbps effective), while the RTX 3050 6 GB runs at 1750 MHz (14 Gbps effective). Despite the RTX 3050 6 GB's higher effective memory clock, the MI300's 8192-bit bus provides over 30 times the bandwidth.

The compute unit configurations reflect their different purposes. The MI300 has 14,080 shading units and 880 TMUs, but zero ROPs. The RTX 3050 6 GB has 2,304 shading units, 72 TMUs, and 32 ROPs. The MI300's lack of ROPs means it cannot perform pixel output, confirming its role as a pure compute accelerator. The RTX 3050 6 GB includes 18 RT cores and 72 tensor cores, enabling hardware ray tracing and tensor operations. The MI300 does not list RT cores or tensor cores, indicating that any such functionality, if present, is not exposed through the same mechanisms.

The interface and connectivity also differ. The MI300 uses PCIe 5.0 x16, while the RTX 3050 6 GB uses PCIe 4.0 x8. The MI300 has no display outputs, while the RTX 3050 6 GB provides 1x HDMI 2.1 and 3x DisplayPort 1.4a. The MI300 supports no graphics APIs, while the RTX 3050 6 GB supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 3050 6 GB is dual-slot, while the MI300's slot width is not recorded. The MI300 requires 2x 8-pin power connectors, whereas the RTX 3050 6 GB draws power without any external connectors.

The Verdict

The recorded data indicates that the AMD Instinct MI300 and NVIDIA GeForce RTX 3050 6 GB are not competitors in any meaningful sense. The MI300 is a compute accelerator designed for massive parallel workloads, evidenced by its 47.87 TFLOPS FP32 throughput, 128 GB HBM3 memory with 5.32 TB/s bandwidth, and 600 W power draw. It has no display outputs, no graphics API support, and no rasterization capability, with a pixel rate of 0 MPixel/s. The RTX 3050 6 GB is a consumer graphics card with 6.774 TFLOPS FP32, 6 GB GDDR6 memory at 168.0 GB/s, 70 W power draw, full display outputs, and support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4.

For compute-intensive tasks such as large-scale simulation, AI training, or data processing where graphics output is irrelevant, the MI300's specifications provide an overwhelming advantage in raw throughput and memory capacity. The 14,080 shading units and 880 TMUs dwarf the RTX 3050 6 GB's 2,304 shading units and 72 TMUs. The MI300's 153,000 million transistors provide the physical foundation for these workloads. However, the MI300 requires a 1000 W power supply and 2x 8-pin connectors, a substantial infrastructure commitment.

For any workload that requires rendering to a display, gaming, or desktop graphics, the RTX 3050 6 GB is the only option between the two. Its 47.04 GPixel/s pixel rate, 32 ROPs, and 18 RT cores enable actual graphics output that the MI300 cannot perform. The RTX 3050 6 GB's position in the 15th percentile of all GPUs indicates modest performance relative to the broader database, but it remains fully functional for consumer graphics tasks. Its 70 W TDP and lack of external power connectors make installation straightforward in most systems.

The database shows no direct head-to-head benchmarks between these two products, which is consistent with their divergent market positioning. The MI300's absence from the benchmark suite and its zero average benchmark score reflect its compute-oriented design rather than a performance deficiency. Users requiring a graphics card for visual output should select the RTX 3050 6 GB. Users requiring a compute accelerator for non-graphical workloads should consider the MI300 based on its recorded specifications. The data supports no other conclusion.
