AMD Instinct MI350P vs AMD Ryzen Z1 GPU Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark results for the AMD Instinct MI350P and the AMD Ryzen Z1 GPU. Both entries show an average benchmark score of 0 and an identical percentile rank of 50 against all GPUs. This absence of measured performance data means the comparison must rely entirely on architectural specifications and theoretical compute figures.

The raw compute numbers reveal a dramatic gap. The Instinct MI350P delivers 36.04 TFLOPS of FP32 performance, while the Ryzen Z1 GPU produces 2.560 TFLOPS. That places the MI350P at roughly 14 times the FP32 throughput of the Z1. In FP16, the MI350P again shows 36.04 TFLOPS with a 1:1 ratio, whereas the Z1 reaches 5.120 TFLOPS using a 2:1 ratio. The MI350P's FP16 output is about 7 times higher, but the ratio difference matters: the Z1 doubles its FP16 rate relative to FP32, while the MI350P maintains parity.

Texture throughput follows the same pattern. The MI350P achieves 1,126.4 GTexel/s, compared to 40.00 GTexel/s for the Z1, a factor of roughly 28. Pixel rate, however, inverts: the Z1 manages 20.00 GPixel/s, while the MI350P is recorded at 0 MPixel/s, because the Instinct card has no raster output units. This is a fundamental design split, not a performance deficiency.

Memory bandwidth reinforces the divide. The MI350P accesses 8.19 TB/s through an 8192-bit HBM3e interface, while the Z1 uses a 64-bit LPDDR5 bus for 51.20 GB/s. That is a 160-fold difference in bandwidth. Capacity also differs massively: 144 GB versus 16 GB.

The Z1 does support ray tracing with 4 dedicated cores, a feature entirely absent from the MI350P's specification sheet. The MI350P lists no RT cores and no tensor cores, while the Z1 also omits tensor cores but includes the RT hardware.

FAQ

Q: Why does the Instinct MI350P show a pixel rate of 0 MPixel/s?

A: The MI350P has 0 ROPs (raster output units) and no display outputs. Its architecture is compute-focused, not graphics-oriented, so it does not perform traditional pixel rasterization. The Ryzen Z1 GPU, by contrast, has 8 ROPs and a pixel rate of 20.00 GPixel/s.

Q: Which GPU has a higher boost clock?

A: The Ryzen Z1 GPU boosts to 2500 MHz, while the Instinct MI350P boosts to 2200 MHz. The Z1 also has a higher base clock at 1500 MHz versus 1000 MHz for the MI350P.

Q: What is the transistor density difference between the two chips?

A: The Ryzen Z1 GPU's Phoenix chip has a transistor density of 142.6M per mm², while the MI350P's MI350 128CU chip has 61.3M per mm². The Z1 packs more transistors per area despite using an older 4 nm process, because the MI350P's 1190 mm² die is much larger.

Q: Does the Instinct MI350P support DirectX or Vulkan?

A: No. The MI350P lists DirectX, OpenGL, and Vulkan APIs as "N/A". The Ryzen Z1 GPU supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Q: How much memory bandwidth does each GPU provide?

A: The Instinct MI350P provides 8.19 TB/s from 144 GB of HBM3e on an 8192-bit bus. The Ryzen Z1 GPU provides 51.20 GB/s from 16 GB of LPDDR5 on a 64-bit bus.

Q: What is the power connector requirement for each?

A: The Instinct MI350P uses a single 16-pin connector and has a TDP of 600 W with a suggested PSU of 1000 W. The Ryzen Z1 GPU has no power connectors and a TDP of 30 W, with no suggested PSU listed.

Architecture Differences

The two GPUs belong to completely different architectural families. The Instinct MI350P uses CDNA 4.0, AMD's compute-focused design, while the Ryzen Z1 GPU uses RDNA 3.0, AMD's graphics-oriented architecture. This single distinction explains most of the divergence in features.

The MI350P is built on a 3 nm process from TSMC, while the Z1 uses TSMC's 4 nm node. Despite the newer node, the MI350P has a transistor density of 61.3M per mm², far lower than the Z1's 142.6M per mm². The MI350P compensates with an enormous 1190 mm² die containing 73,000 million transistors, versus the Z1's 178 mm² die with 25,390 million transistors.

Shading resources differ by an order of magnitude. The MI350P contains 8192 shading units and 512 TMUs, while the Z1 has 256 shading units and 16 TMUs. The MI350P has zero ROPs, which aligns with its lack of display outputs. The Z1 includes 8 ROPs and 4 ray tracing cores, making it a complete graphics processor.

The memory subsystems reflect their intended workloads. HBM3e on the MI350P provides 144 GB at 8.19 TB/s, a configuration for massive data sets and high-bandwidth compute. LPDDR5 on the Z1 provides 16 GB at 51.20 GB/s, suitable for integrated graphics in a compact device. The MI350P's 8192-bit bus dwarfs the Z1's 64-bit bus.

Clock behavior also differs. The Z1 runs at a base of 1500 MHz and boosts to 2500 MHz, while the MI350P starts at 1000 MHz and boosts to 2200 MHz. The Z1's higher clocks reflect a power envelope of 30 W, while the MI350P operates at 600 W. The MI350P's memory clock is 2000 MHz with 8 Gbps effective, while the Z1's memory runs at 800 MHz with 6.4 Gbps effective.

API support splits them completely. The MI350P lists no graphics APIs, while the Z1 supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The MI350P has no display outputs, reinforcing its role as an accelerator rather than a graphics card.

Dimensions: the MI350P measures 267 mm long, 111 mm high, and 40 mm wide. The Z1 measures 280 mm long, 111 mm high, and 21 mm wide. The Z1 is longer but much thinner.

Release dates: the MI350P is dated 2026-05-06, while the Z1 is dated 2023-09-17. The Z1 has a production status of "Active" and a launch MSRP of 599 USD. The MI350P has no listed production status and no launch MSRP.

The Verdict

The data describes two devices with no functional overlap. The Instinct MI350P is a compute accelerator with no graphics output, no graphics API support, and no rasterization capability. The Ryzen Z1 GPU is a graphics processor with full DirectX 12 Ultimate support, ray tracing cores, and pixel rendering hardware.

For raw compute throughput, the MI350P dominates. Its FP32 figure of 36.04 TFLOPS is roughly 14 times the Z1's 2.560 TFLOPS. Its FP16 output is 36.04 TFLOPS versus 5.120 TFLOPS. Texture rate is 28 times higher. Memory bandwidth is 160 times higher. These are not incremental differences; they represent entirely different performance classes.

For graphics work, the Z1 is the only option. The MI350P cannot render pixels, output video, or run graphics APIs. The Z1's 20.00 GPixel/s pixel rate and 4 RT cores provide actual display capability, even if the raw numbers are modest.

The power and physical requirements confirm the split. The MI350P needs 600 W, a 1000 W PSU, a 16-pin connector, and a dual-slot chassis. The Z1 runs on 30 W with no external power. The MI350P is a data-center part; the Z1 is an embedded or mobile part.

The release timeline also matters. The Z1 launched in September 2023 and remains active. The MI350P is dated May 2026, indicating a future or planned product. The Z1 carries a launch MSRP of 599 USD; the MI350P has no price recorded.

Where Each One Wins

The Instinct MI350P wins in every compute-heavy category. Its FP32 and FP16 throughput of 36.04 TFLOPS each positions it for high-performance computing workloads. The 8.19 TB/s memory bandwidth and 144 GB capacity suit large-scale data processing. The 1,126.4 GTexel/s texture rate indicates strong shader throughput for non-raster tasks. The 8192 shading units and 512 TMUs provide massive parallel execution resources.

The Ryzen Z1 GPU wins in every graphics-related category. Its 20.00 GPixel/s pixel rate and 8 ROPs enable actual rasterization. The 4 ray tracing cores add hardware-accelerated ray tracing. DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support cover modern graphics APIs. The 2500 MHz boost clock and 1500 MHz base clock are higher than the MI350P's, which helps latency-sensitive rendering.

The Z1 also wins on efficiency metrics. Its 30 W TDP versus 600 W means the Z1 delivers graphics capability at a fraction of the power draw. The Z1's 142.6M per mm² transistor density versus 61.3M per mm² shows a more compact design. The Z1's 16 GB memory is sufficient for its graphics role, while the MI350P's 144 GB serves a different purpose.

Physical form favors the Z1 for compact integration. At 280 mm long and 21 mm wide, it fits into tighter spaces than the MI350P's 267 mm by 40 mm profile. The Z1 requires no power connector, simplifying installation. The MI350P's dual-slot width and 16-pin connector demand more infrastructure.

The production status and release dates also split the field. The Z1 is active and available since 2023. The MI350P is dated for 2026, with no production status. For immediate deployment, the Z1 is the only real option. For future high-performance compute, the MI350P's specifications point to a purpose-built accelerator with no graphics pretensions.
