AMD Instinct MI350X vs AMD Radeon RX 9070 GRE Comparison

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark comparisons between the AMD Instinct MI350X and the AMD Radeon RX 9070 GRE. The Instinct MI350X has no benchmark entries in the database, resulting in an average benchmark score of zero and a percentile ranking of 50 among all GPUs. The Radeon RX 9070 GRE, by contrast, has two recorded benchmarks: a 3DMark Steel Nomad DX12 score of 5424 and a Geekbench OpenCL score of 109309. Its average benchmark score stands at 57367, placing it in the 87th percentile of all GPUs.

The absence of benchmark data for the Instinct MI350X means the database cannot quantify its real-world performance against the RX 9070 GRE. However, the theoretical specifications reveal a massive computational disparity. The Instinct MI350X delivers 72.09 TFLOPS of FP32 compute, more than double the 34.28 TFLOPS of the RX 9070 GRE. Its texture rate reaches 2,252.8 GTexel/s, compared to 535.7 GTexel/s for the Radeon. The Instinct card also has 16,384 shading units versus 3,072, and 1,024 texture mapping units versus 192.

The RX 9070 GRE counters in pixel throughput. It achieves 267.8 GPixel/s, while the Instinct MI350X is recorded at 0 MPixel/s. This indicates the Instinct card is not designed for rasterized pixel output, consistent with its lack of display outputs. The Radeon also has 96 ROPs, while the Instinct has zero. These differences confirm they target entirely separate workloads.

Architecture Differences

The Instinct MI350X uses the CDNA 4.0 architecture on the MI350 256CU chip, fabricated on a 3 nm process at TSMC. The RX 9070 GRE uses RDNA 4.0 on the Navi 48 chip, built on a 4 nm process, also at TSMC. The process node difference gives the Instinct a manufacturing advantage, though the Radeon compensates with a higher transistor density: 151.0M per mm² versus 77.7M per mm² for the Instinct. The Instinct die measures 2380 mm² and contains 185,000 million transistors, while the Radeon die is 357 mm² with 53,900 million transistors.

Memory architecture separates the two decisively. The Instinct MI350X carries 288 GB of HBM3e memory on a 8192-bit bus, delivering 8.19 TB/s of bandwidth. The RX 9070 GRE has 12 GB of GDDR6 on a 192-bit bus, achieving 432.0 GB/s. The Instinct's memory bandwidth is roughly 19 times higher, a critical factor for large-scale compute workloads that the database data supports. The Radeon uses a smaller but faster-clocked memory subsystem: 2250 MHz with 18 Gbps effective transfer, versus 2000 MHz with 8 Gbps effective for the Instinct.

Clock speeds favor the Radeon in raw frequency. The RX 9070 GRE has a base clock of 1420 MHz and a boost of 2790 MHz, with a game clock of 2220 MHz. The Instinct MI350X runs at 1000 MHz base and 2200 MHz boost. The Radeon's boost clock is 590 MHz higher, reflecting its consumer-oriented design. The Instinct compensates with far more compute units and memory parallelism.

The Instinct MI350X includes no RT cores, no display outputs, and no API support for DirectX, OpenGL, or Vulkan. The RX 9070 GRE includes 48 RT cores, supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, and offers 1x HDMI 2.1b plus 3x DisplayPort 2.1a outputs. The Instinct uses an OAM module slot width with no power connectors and a suggested PSU of 1400 W. The Radeon is a dual-slot card with 2x 8-pin power connectors and a 550 W suggested PSU. The TDP difference is substantial: 1000 W for the Instinct versus 220 W for the Radeon.

The Verdict

The data indicates the AMD Instinct MI350X is built for compute density, not graphics output. Its 288 GB HBM3e memory, 8192-bit bus, and 72.09 TFLOPS FP32 performance position it for server-side acceleration, AI training, and scientific simulation. The lack of any display outputs, API support, or pixel rate confirms it cannot function as a traditional graphics card. The Radeon RX 9070 GRE, with its 12 GB GDDR6, 48 RT cores, and full graphics API stack, is a consumer GPU for gaming and workstation graphics.

The RX 9070 GRE's nearest rivals in the database provide context for its performance tier. It sits 0.7% below the Intel Arc A580 in average benchmark score, 1.2% below the AMD Radeon RX 5600 OEM, 1.5% below the Intel Arc A570M, and 1.8% below the AMD Radeon RX 6950 XT. These deltas are small, indicating the RX 9070 GRE performs within a tight band of mid-range to upper-mid-range GPUs. Its 87th percentile ranking among all GPUs reflects solid overall capability.

For the Instinct MI350X, the database records no benchmark scores, so no percentile-based verdict is possible. Its 50th percentile ranking is a placeholder, not a performance measure. The theoretical specifications, however, show a compute device that outclasses the Radeon in shading units, texture rate, FP32 throughput, and memory bandwidth by wide margins. Any user selecting between these two cards would choose based on workload: the Instinct for datacenter compute, the Radeon for graphics rendering.

Where Each One Wins

The AMD Instinct MI350X wins decisively in compute-heavy scenarios. Its 16,384 shading units and 1,024 TMUs provide massive parallel throughput for AI training, deep learning inference, and scientific simulation. The 288 GB HBM3e memory with 8.19 TB/s bandwidth supports datasets far larger than any consumer GPU can hold, and the 3 nm process node with 185,000 million transistors indicates a chip designed for sustained datacenter workloads. The 1000 W TDP and OAM module form factor confirm it belongs in server racks, not desktop towers. Its FP32 and FP16 performance are identical at 72.09 TFLOPS, simplifying mixed-precision workflows.

The AMD Radeon RX 9070 GRE wins in every graphics-oriented category. Its 267.8 GPixel/s pixel rate, 96 ROPs, and 48 RT cores enable rasterized rendering and ray-traced effects. The 12 GB GDDR6 memory, while smaller, operates at 18 Gbps effective with a 2790 MHz boost clock, suitable for high-refresh gaming at standard resolutions. The dual-slot design, 2x 8-pin power connectors, and 550 W suggested PSU make it installable in conventional systems. Full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support ensure broad software compatibility. Its 87th percentile ranking and proximity to rivals like the Intel Arc A580 (0.7% lower) and AMD Radeon RX 6950 XT (1.8% lower) place it in a competitive mid-range segment.

The data supports a clear division: the Instinct MI350X for compute density and memory capacity, the Radeon RX 9070 GRE for graphics output and consumer accessibility. Neither card can substitute for the other in its primary role. The Instinct lacks display outputs and API support, and the Radeon lacks the memory bandwidth and compute unit count for large-scale parallel processing. Users with compute needs should consider the Instinct MI350X; users with graphics needs should consider the Radeon RX 9070 GRE.
