AMD Instinct MI350P vs AMD Radeon RX 7700 Comparison

Where Each One Wins

The recorded data separates these two AMD accelerators by intended workload rather than by direct competition. The AMD Instinct MI350P is a compute-oriented accelerator with no display outputs and no graphics API support, which places it firmly in data center and scientific computing territory. The AMD Radeon RX 7700 is a consumer graphics card with full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support, plus three display outputs, which makes it suitable for rendering, gaming, and general desktop use.

The Radeon RX 7700 holds a percentile rank of 58 among all GPUs in the database, while the Instinct MI350P sits at percentile 50. The RX 7700 also carries a full set of benchmark scores, including a 3DMark Steel Nomad DX12 score of 2865, a Geekbench OpenCL score of 106028, and a Passmark G3D score of 20974. The MI350P has no recorded benchmark scores in the database, so its wins are defined by architectural capacity rather than measured tests.

The use-case split is clear. The MI350P wins in memory capacity, memory bandwidth, compute unit count, and FP32 throughput. The RX 7700 wins in rasterization features, pixel throughput, graphics API coverage, and measured benchmark results. For workloads that require large model residency, such as AI inference or simulation, the MI350P provides 144 GB of HBM3e memory with 8.19 TB/s bandwidth. For workloads that require rendering frames to a display, the RX 7700 provides ROPs, ray accelerators, and a 236.1 GPixel/s pixel rate.

The RX 7700 also wins in transistor density. Its 5 nm TSMC process packs 28,100 million transistors into a 346 mm² die, yielding 81.2 million transistors per mm². The MI350P uses a 3 nm process with 73,000 million transistors on a 1190 mm² die, which yields 61.3 million transistors per mm². The smaller process node does not translate to higher density because the MI350P die is substantially larger and includes HBM3e memory interfaces.

Architecture Differences

The two cards use different architectures from different generations. The MI350P uses CDNA 4.0, AMD's compute-focused architecture, built on a 3 nm TSMC process. The RX 7700 uses RDNA 3.0, AMD's graphics-focused architecture, built on a 5 nm TSMC process. The MI350P belongs to the Instinct (MIx) generation, while the RX 7700 belongs to the Radeon RX 7000 series and the Navi III (RX 7000) generation.

The chip designs differ fundamentally. The MI350P uses the MI350 128CU chip with 8192 shading units, 512 texture mapping units, and zero ROPs. The RX 7700 uses the Navi 32 chip with 2560 shading units, 160 TMUs, 96 ROPs, and 40 ray tracing cores. The MI350P has no pixel rate because it lacks ROPs entirely, recording 0 MPixel/s. The RX 7700 delivers 236.1 GPixel/s.

Memory architecture separates the two products even further. The MI350P uses 144 GB of HBM3e on an 8192-bit bus, producing 8.19 TB/s of bandwidth. The RX 7700 uses 16 GB of GDDR6 on a 256-bit bus, producing 624.1 GB/s of bandwidth. The MI350P memory clock is 2000 MHz with 8 Gbps effective transfer, while the RX 7700 memory clock is 2438 MHz with 19.5 Gbps effective transfer. The MI350P trades the higher per-pin transfer rate of GDDR6 for the massive bus width and capacity of HBM3e.

Clock behavior also differs. The MI350P runs a 1000 MHz base clock and 2200 MHz boost clock. The RX 7700 runs a 1900 MHz base clock, 2041 MHz game clock, and 2459 MHz boost clock. The RX 7700 operates at higher frequencies across the board, which helps its rasterization throughput despite having fewer shading units.

The power and interface profiles reflect their different deployment environments. The MI350P draws a 600 W TDP with a single 16-pin connector and requires a 1000 W suggested PSU. The RX 7700 draws a 200 W TDP with two 8-pin connectors and requires a 550 W suggested PSU. The MI350P uses PCIe 5.0 x16, while the RX 7700 uses PCIe 4.0 x16. The MI350P has no display outputs; the RX 7700 has 1x HDMI 2.1a, 2x DisplayPort 2.1, and 1x USB Type-C.

Physical dimensions are similar in length but differ in height and width. Both cards are 267 mm long. The MI350P is 111 mm tall and 40 mm wide. The RX 7700 is 135 mm tall and 50 mm wide. The RX 7700 is bulkier in both dimensions.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between these two products. The MI350P has no benchmark scores recorded, and the headToHeadBenchmarks array is empty. The comparison therefore relies on the RX 7700's measured scores and the MI350P's architectural specifications.

The RX 7700 delivers a Passmark G3D score of 20974, a Passmark GPU Compute score of 10963, and a Geekbench OpenCL score of 106028. Its 3DMark Steel Nomad DX12 score is 2865. These measurements place it at percentile 58 with an average benchmark score of 15852. Its nearest rivals in the database are the AMD Radeon R9 370X at 15862 average score and a delta of -0.1%, the AMD Radeon RX 9060 at 16014 with a delta of -1%, the AMD Radeon Pro W5500 at 15679 with a delta of 1.1%, and the NVIDIA GeForce RTX 3060 Ti at 16129 with a delta of -1.7%. The RX 7700 trails the R9 370X and RX 9060 by fractions of a percent, leads the Pro W5500 by 1.1%, and trails the RTX 3060 Ti by 1.7%.

The MI350P has an average benchmark score of 0 and no nearest rivals listed. Its FP32 throughput of 36.04 TFLOPS exceeds the RX 7700's 25.18 TFLOPS by roughly 43%. Its texture rate of 1,126.4 GTexel/s exceeds the RX 7700's 393.4 GTexel/s by a factor of 2.86. Its memory bandwidth of 8.19 TB/s exceeds the RX 7700's 624.1 GB/s by more than 13 times.

The RX 7700 counters in pixel throughput with 236.1 GPixel/s versus the MI350P's 0 MPixel/s. It also supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the MI350P reports N/A for all three APIs. The RX 7700 has 96 ROPs and 40 ray tracing cores; the MI350P has no ROPs and no ray tracing cores listed.

The FP16 figures mirror the FP32 figures for both cards. The MI350P delivers 36.04 TFLOPS FP16 at a 1:1 ratio, and the RX 7700 delivers 25.18 TFLOPS FP16 at a 1:1 ratio. Neither card uses a separate FP16 acceleration path.
