AMD Instinct MI350P vs AMD Radeon RX 7600 XT Comparison

Where Each One Wins

The AMD Instinct MI350P and the AMD Radeon RX 7600 XT occupy entirely different segments of the GPU market, and the recorded data reflects this split clearly. The Instinct MI350P is an accelerator built for compute throughput, with no display outputs and no graphics API support. The RX 7600 XT is a consumer graphics card with full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support, plus HDMI and DisplayPort outputs.

The Instinct MI350P wins on raw compute capacity. Its FP32 throughput is 36.04 TFLOPS, compared to 22.57 TFLOPS for the RX 7600 XT. That is a 59.7% advantage in single-precision floating-point work. The MI350P also delivers 1,126.4 GTexel/s of texture fill rate versus 352.6 GTexel/s for the RX 7600 XT, a 3.2x gap. Memory bandwidth is the largest differentiator: the MI350P provides 8.19 TB/s from 144 GB of HBM3e on a 8192-bit bus, while the RX 7600 XT has 288.0 GB/s from 16 GB of GDDR6 on a 128-bit bus.

The RX 7600 XT wins on graphics-specific workloads. It has a pixel rate of 176.3 GPixel/s; the MI350P has 0 MPixel/s because it lacks rasterization hardware (ROPs are listed as 0). The RX 7600 XT also has 32 ray tracing cores, whereas the MI350P lists no RT cores. For any display-driven task, gaming, or graphics API workload, the RX 7600 XT is the functional option. The MI350P cannot output video and has no DirectX, OpenGL, or Vulkan support, making it unsuitable for conventional graphics use.

The benchmark database shows a 50th percentile rank for the MI350P among all GPUs, but it has no recorded benchmark scores. The RX 7600 XT sits at the 60th percentile with an average benchmark score of 17,083. The absence of scores for the MI350P means its percentile is based on specifications alone, not measured performance.

Architecture Differences

The two GPUs use different architectures from AMD. The Instinct MI350P is built on CDNA 4.0, designed for compute acceleration, while the RX 7600 XT uses RDNA 3.0, optimized for graphics rendering. The codename for the RX 7600 XT is Hotpink Bonefish, and its chip is Navi 33. The MI350P uses the MI350 128CU chip.

Process technology differs substantially. The MI350P is manufactured on a 3 nm process at TSMC, while the RX 7600 XT uses a 6 nm process, also at TSMC. The MI350P has 73,000 million transistors on a 1190 mm² die, giving a transistor density of 61.3M / mm². The RX 7600 XT has 13,300 million transistors on a 204 mm² die, with a density of 65.2M / mm². Despite the larger node, the RX 7600 XT packs transistors slightly more densely.

The MI350P has 8192 shading units and 512 TMUs, but no ROPs. The RX 7600 XT has 2048 shading units, 128 TMUs, and 64 ROPs. The MI350P's architecture omits graphics-specific hardware entirely, which is consistent with its lack of display outputs and API support. The RX 7600 XT includes 32 ray tracing cores, a feature absent from the MI350P's specification list.

Memory architecture is fundamentally different. The MI350P uses HBM3e with a 8192-bit bus and 8.19 TB/s bandwidth. The RX 7600 XT uses GDDR6 with a 128-bit bus and 288.0 GB/s bandwidth. The MI350P's memory capacity of 144 GB is 9 times larger than the RX 7600 XT's 16 GB. The bus width difference (8192 bits versus 128 bits) explains the massive bandwidth gap.

Clock behavior differs as well. The MI350P has a base clock of 1000 MHz and a boost clock of 2200 MHz. The RX 7600 XT has a base clock of 1980 MHz, a game clock of 2470 MHz, and a boost clock of 2755 MHz. The RX 7600 XT runs at higher frequencies, but the MI350P compensates with far more compute units and memory bandwidth.

Head-to-Head Benchmarks

The head-to-head benchmark table in the database is empty, so no direct comparison scores exist between the MI350P and the RX 7600 XT. However, the RX 7600 XT has a full set of recorded benchmarks, and its nearest rivals provide context for its performance tier.

In 3DMark Steel Nomad DX12, the RX 7600 XT scores 2,348. In Geekbench OpenCL, it scores 92,426, and in Geekbench Vulkan, 48,366. Passmark results include DirectX 10 at 85, DirectX 11 at 167, DirectX 12 at 65, and DirectX 9 at 228. The Passmark G2D score is 1,030, G3D is 17,132, and GPU compute is 8,987.

The RX 7600 XT's nearest rivals show a tight cluster. The NVIDIA GeForce GTX 690 has an average score of 17,037, which is 0.3% below the RX 7600 XT. The AMD Radeon HD 7970M averages 17,019, 0.4% lower. The NVIDIA GeForce RTX 3070 averages 17,208, which is 0.7% higher than the RX 7600 XT. The NVIDIA Tesla M4 averages 16,932, 0.9% lower. These deltas indicate the RX 7600 XT performs within 1% of these four rivals, a remarkably narrow band.

The MI350P has no benchmark scores in the database, so its actual performance cannot be compared numerically to the RX 7600 XT. The specification comparison shows the MI350P should dominate compute-heavy workloads, but no measured data confirms this. The RX 7600 XT's measured results place it in a competitive position against mid-range and older high-end GPUs from NVIDIA.

Specification Differences

The two cards differ in nearly every specification category. The MI350P uses a 3 nm process; the RX 7600 XT uses 6 nm. Transistor count is 73,000 million versus 13,300 million. Die size is 1190 mm² versus 204 mm². The MI350P has a base clock of 1000 MHz and boost of 2200 MHz; the RX 7600 XT has base 1980 MHz, game 2470 MHz, and boost 2755 MHz. Memory clock is 2000 MHz (8 Gbps effective) for the MI350P versus 2250 MHz (18 Gbps effective) for the RX 7600 XT.

Memory capacity is 144 GB HBM3e versus 16 GB GDDR6. Bus width is 8192 bit versus 128 bit. Bandwidth is 8.19 TB/s versus 288.0 GB/s. Shading units are 8192 versus 2048. TMUs are 512 versus 128. ROPs are 0 versus 64. The RX 7600 XT has 32 RT cores; the MI350P has none listed. Pixel rate is 0 MPixel/s versus 176.3 GPixel/s. Texture rate is 1,126.4 GTexel/s versus 352.6 GTexel/s. FP32 is 36.04 TFLOPS versus 22.57 TFLOPS. FP16 is 36.04 TFLOPS (1:1) for both, though the MI350P's matching FP16 rate means it does not gain the 2x advantage some compute cards show.

Power and cooling differ sharply. The MI350P has a TDP of 600 W and requires a 1000 W PSU, with a 1x 16-pin power connector. The RX 7600 XT has a TDP of 190 W, a 450 W PSU recommendation, and a 1x 8-pin connector. Both are dual-slot cards, but dimensions differ: the MI350P is 267 mm long, 111 mm tall, and 40 mm wide; the RX 7600 XT is 204 mm long and 115 mm tall, with no width listed.

Bus interface differs: PCIe 5.0 x16 for the MI350P versus PCIe 4.0 x8 for the RX 7600 XT. Display outputs are absent on the MI350P, while the RX 7600 XT has 1x HDMI 2.1a and 3x DisplayPort 2.1. API support is entirely absent for the MI350P, while the RX 7600 XT supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Release dates differ: the MI350P is dated 2026-05-06, and the RX 7600 XT is dated 2024-01-23. The RX 7600 XT has a launch MSRP of 329 USD, stated once here. The MI350P has no launch MSRP listed.
