AMD Instinct MI350P vs NVIDIA RTX A1000 Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark scores for the AMD Instinct MI350P and the NVIDIA RTX A1000. However, the available benchmark database entries provide a clear picture for the RTX A1000. Its average benchmark score of 34,207 places it in the 79th percentile among all GPUs, meaning it outperforms roughly four out of every five recorded graphics cards. The AMD Instinct MI350P, in contrast, has no recorded benchmark scores and sits at the 50th percentile with an average score of 0, indicating that no comparable workload measurements exist in the database for this accelerator.

For the RTX A1000, the strongest recorded result comes from the Geekbench OpenCL test, where it scored 52,078. The Vulkan result is close behind at 49,574, showing a 5.1% gap between the two API paths. The 3DMark Steel Nomad DX12 test returns a much lower score of 969, which reflects the demanding nature of that workload versus the A1000's workstation-oriented design. In relative terms, the RTX A1000's nearest rivals in the database are tightly clustered: the NVIDIA RTX A2000 12 GB scores 34,154 (0.2% behind), the AMD Radeon RX 560 XT scores 34,133 (0.2% behind), the NVIDIA TITAN V scores 34,355 (0.4% ahead), and the AMD Radeon RX 480 scores 33,997 (0.6% behind). The A1000 is effectively at parity with all four, with deltas under one percentage point in either direction.

Because the MI350P has no benchmark entries, the head-to-head comparison is limited to architectural and specification-level analysis rather than measured performance deltas. The absence of recorded scores for the MI350P means the database cannot currently quantify any performance advantage for either card in user-facing tests.

Architecture Differences

The architectural divide between these two accelerators is substantial. The AMD Instinct MI350P uses the CDNA 4.0 architecture built on a 3 nm process at TSMC, whereas the NVIDIA RTX A1000 uses the Ampere architecture on an 8 nm process at Samsung. The MI350P integrates 73,000 million transistors on a 1,190 mm² die, yielding a transistor density of 61.3 million per mm². The A1000 integrates 8,700 million transistors on a 200 mm² die, for a density of 43.5 million per mm². The MI350P's die is nearly six times larger and its transistor count is over eight times higher.

The MI350P's chip is designated as MI350 128CU, which aligns with its 8,192 shading units, 512 texture mapping units, and no raster operation pipelines (0 ROPs). It also reports no pixel rate (0 MPixel/s), indicating the card is not designed for traditional rasterized graphics output. The RTX A1000, by contrast, is built around the GA107 chip with 2,304 shading units, 72 TMUs, and 32 ROPs. It includes 18 ray tracing cores and 72 tensor cores, features absent from the MI350P's specification sheet. The A1000 also delivers a pixel rate of 46.78 GPixel/s and a texture rate of 105.3 GTexel/s, while the MI350P's texture rate is 1,126.4 GTexel/s.

API support differs sharply. The MI350P lists DirectX, OpenGL, and Vulkan as N/A, reflecting its compute-focused design with no display outputs. The RTX A1000 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, and provides four mini-DisplayPort 1.4a outputs. Memory technology also diverges: the MI350P uses HBM3e with a 8,192-bit bus and 8.19 TB/s bandwidth, while the A1000 uses GDDR6 with a 128-bit bus and 192.0 GB/s bandwidth. The MI350P's memory capacity is 144 GB versus 8 GB for the A1000.

Clock behavior differs as well. The MI350P has a 1000 MHz base clock and 2200 MHz boost clock, with memory running at 2000 MHz (8 Gbps effective). The A1000 runs at 727 MHz base and 1462 MHz boost, with memory at 1500 MHz (12 Gbps effective). Despite the A1000's higher effective memory data rate, its narrow bus and smaller capacity produce far lower total bandwidth.

The Verdict

The database makes the functional separation clear. The AMD Instinct MI350P is a high-density compute accelerator with 36.04 TFLOPS FP32, 144 GB of HBM3e memory, and 8.19 TB/s of bandwidth, but it has no display outputs and no graphics API support. The NVIDIA RTX A1000 is a workstation graphics card with 6.737 TFLOPS FP32, 8 GB of GDDR6, ray tracing and tensor cores, and full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support, plus four display outputs. The MI350P's transistor count of 73,000 million versus 8,700 million, its 3 nm process versus 8 nm, and its 600 W TDP versus 50 W all point to opposite design goals. The MI350P targets memory-bound compute workloads where capacity and bandwidth dominate, while the A1000 targets traditional workstation tasks requiring graphics output and API compatibility. Neither card substitutes for the other in the database's recorded feature set.

Where Each One Wins

The AMD Instinct MI350P wins on raw compute scale. Its FP32 output of 36.04 TFLOPS is over five times the A1000's, and its FP16 output matches at 36.04 TFLOPS versus 6.737 TFLOPS. Its memory capacity of 144 GB is 18 times larger, and its bandwidth of 8.19 TB/s is over 40 times higher. The card's 73,000 million transistors, 8,192 shading units, and 512 TMUs give it a structural advantage for large parallel workloads. Its 2200 MHz boost clock also exceeds the A1000's 1462 MHz boost. The MI350P's 3 nm process and 61.3M / mm² transistor density indicate a more advanced manufacturing node, and the PCIe 5.0 x16 interface doubles the A1000's PCIe 4.0 x8 link width.

The NVIDIA RTX A1000 wins on versatility and efficiency. It provides 4x mini-DisplayPort 1.4a outputs, DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4 support, enabling standard graphics workloads that the MI350P cannot handle. Its 50 W TDP is 12 times lower than the MI350P's 600 W, and its suggested PSU of 250 W is one quarter of the MI350P's 1000 W requirement. The A1000 is single-slot versus dual-slot, uses no power connectors, and is shorter (163 mm versus 267 mm). It also includes 18 ray tracing cores and 72 tensor cores, features missing from the MI350P's spec sheet. The A1000's 46.78 GPixel/s pixel rate confirms its rasterization capability, whereas the MI350P records 0 MPixel/s. The A1000 also holds a production status of Active, while the MI350P lists none. For any workload requiring display output, graphics APIs, or low power draw, the A1000 is the only option between the two.
