Architecture Differences

The AMD Instinct MI355X and NVIDIA GeForce RTX 3050 6 GB represent opposite ends of the GPU design spectrum. The MI355X uses a 3 nm TSMC process and contains 185,000 million transistors on a 2380 mm² die, yielding a density of 77.7 million transistors per mm². The RTX 3050 6 GB uses an 8 nm Samsung process with 8,700 million transistors on a 200 mm² die, yielding 43.5 million transistors per mm². The density gap reflects the different foundry nodes and design goals.

The MI355X is built on CDNA 4.0, an architecture aimed at compute acceleration with no display outputs and no graphics API support. The RTX 3050 6 GB uses Ampere, a consumer architecture supporting DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, with display outputs including 1x HDMI 2.1 and 3x DisplayPort 1.4a.

The compute resources differ dramatically. The MI355X has 16,384 shading units, 1,024 TMUs, and 0 ROPs. The RTX 3050 6 GB has 2,304 shading units, 72 TMUs, and 32 ROPs. The MI355X also includes 18 RT cores and 72 tensor cores, features absent from the MI355X's specification list. The MI355X reports a pixel rate of 0 MPixel/s and a texture rate of 2,457.6 GTexel/s, while the RTX 3050 6 GB reports 47.04 GPixel/s and 105.8 GTexel/s.

Memory architecture follows the same divide. The MI355X uses HBM3e with 288 GB capacity and 8.19 TB/s bandwidth. The RTX 3050 6 GB uses GDDR6 with 6 GB capacity and 168.0 GB/s bandwidth. The MI355X's memory clock is 2000 MHz (8 Gbps effective), while the RTX 3050 6 GB runs at 1750 MHz (14 Gbps effective). The MI355X uses a PCIe 5.0 x16 interface, whereas the RTX 3050 6 GB uses PCIe 4.0 x8.

Physical design also diverges. The MI355X comes as an OAM module measuring 102 mm by 165 mm with no power connectors, requiring an 1800 W PSU. The RTX 3050 6 GB is a dual-slot card measuring 242 mm by 112 mm, also with no power connectors, but only requiring a 250 W PSU. The MI355X has a base clock of 1000 MHz and boost clock of 2400 MHz, versus 1042 MHz base and 1470 MHz boost for the RTX 3050 6 GB.

Head-to-Head Benchmarks

Direct head-to-head benchmark data does not exist in the database. The MI355X has no recorded benchmark entries, while the RTX 3050 6 GB has eight individual test scores. This absence of overlapping measurements means comparisons must rely on architectural specifications and the RTX 3050's recorded performance profile.

The RTX 3050 6 GB's strongest recorded result is in Passmark G3D with a score of 10,738. Its Passmark G2D score is 882, and its Passmark GPU Compute score is 5,192. In DirectX-specific tests, the card scores 124 in Passmark DirectX 9, 72 in DirectX 11, 59 in DirectX 10, and 53 in DirectX 12. Its 3DMark Steel Nomad DX12 score is 1,515.

The RTX 3050 6 GB's average benchmark score is 2,329, which places it at the 15th percentile of all GPUs in the database. Its nearest rivals show a tight cluster: the NVIDIA GeForce GT 640M averages 2,335 (0.3% higher), the NVIDIA Quadro P620 averages 2,339 (0.4% higher), the Intel HD Graphics 510 averages 2,305 (1% lower), and the NVIDIA GeForce GT 550M averages 2,363 (1.4% higher). This indicates the RTX 3050 6 GB sits in a performance band where small percentage differences separate it from older mobile and entry-level parts.

For the MI355X, the only available metric is its 50th percentile ranking across all GPUs, with an average benchmark score of 0. This percentile value suggests the database classifies it as a mid-pack performer overall, but the absence of actual benchmark scores prevents any direct numeric comparison against the RTX 3050 6 GB.

The FP32 compute figures provide the clearest differentiation. The MI355X's 78.64 TFLOPS is 11.6 times the RTX 3050 6 GB's 6.774 TFLOPS. Texture rate shows a similar gap: 2,457.6 GTexel/s versus 105.8 GTexel/s, a factor of about 23. These specification-level comparisons indicate that in pure compute throughput, the MI355X operates in a different performance class entirely.

The Verdict

The data supports a straightforward conclusion: these two products serve completely different purposes and should not be considered direct competitors. The MI355X is a compute accelerator with no display outputs, no graphics API support, and a 1400 W TDP, built for server or datacenter workloads. The RTX 3050 6 GB is an entry-level consumer graphics card with full DirectX 12 Ultimate support, display outputs, and a 70 W TDP.

The RTX 3050 6 GB is the only one with any recorded benchmark scores, and its 15th percentile ranking places it among lower-tier GPUs. Its nearest rivals include mobile GPUs like the GT 640M and GT 550M, plus the Quadro P620 and Intel HD Graphics 510. The MI355X's 50th percentile ranking, despite having no benchmark scores, indicates the database treats it as an average performer among all recorded GPUs, but this is based on its specification profile rather than measured results.

For users needing graphics output, gaming features, or general desktop acceleration, the RTX 3050 6 GB is the only viable option between the two, as the MI355X has no display outputs and no API support. For users needing massive memory capacity, extreme bandwidth, or high-density compute, the MI355X's 288 GB HBM3e and 8.19 TB/s bandwidth are in a completely different category.

The launch MSRP of the RTX 3050 6 GB is 179 USD, which the database records, but the MI355X has no launch MSRP listed. The RTX 3050 6 GB is marked end-of-life, while the MI355X's production status is not specified.

Where Each One Wins

The MI355X wins decisively in compute-heavy, datacenter-oriented specifications. Its 78.64 TFLOPS FP32 and FP16 performance, 2,457.6 GTexel/s texture rate, and 8.19 TB/s memory bandwidth are all far beyond the RTX 3050 6 GB's capabilities. The 288 GB HBM3e memory capacity is 48 times the RTX 3050 6 GB's 6 GB GDDR6. The PCIe 5.0 x16 interface doubles the bus bandwidth potential of the RTX 3050 6 GB's PCIe 4.0 x8 connection. The 3 nm TSMC process and 185,000 million transistors indicate a chip designed for maximum compute density.

The RTX 3050 6 GB wins in every consumer-facing category. It has display outputs, full DirectX 12 Ultimate support, OpenGL 4.6, and Vulkan 1.4. It has 18 RT cores and 72 tensor cores, enabling ray tracing and AI-accelerated workloads. Its 70 W TDP and 250 W suggested PSU make it practical for standard desktop systems, whereas the MI355X requires 1400 W and an 1800 W PSU. The RTX 3050 6 GB also has a 32 ROPs count, giving it a pixel rate of 47.04 GPixel/s, while the MI355X reports 0 ROPs and 0 MPixel/s.

The RTX 3050 6 GB is the only one of the two with recorded benchmark scores. Its Passmark G3D score of 10,738 and 3DMark Steel Nomad DX12 score of 1,515 provide concrete performance data, while the MI355X has no measured results in the database. The RTX 3050 6 GB also has a launch MSRP of 179 USD, giving it a defined market position, while the MI355X has no listed launch price.

For gaming, desktop graphics, video output, or any workload requiring graphics API support, the RTX 3050 6 GB is the clear choice based on the data. For massive parallel compute, large memory footprints, or high-bandwidth data processing without display requirements, the MI355X's specifications dominate. The production status of the RTX 3050 6 GB is end-of-life, meaning it is no longer manufactured, while the MI355X's production status is not recorded, and its release date of 2025-06-11 makes it the newer product by over a year.
