AMD Radeon 860M vs AMD Ryzen Z2 A GPU Comparison

Where Each One Wins

The AMD Radeon 860M and the AMD Ryzen Z2 A GPU occupy different positions in the performance spectrum, and the recorded data shows a clear separation in capability. The Radeon 860M holds a decisive advantage in raw compute performance, with an average benchmark score of 26401 across its recorded tests, while the Ryzen Z2 A GPU has no recorded benchmark scores in the database, placing it at the 50th percentile of all GPUs. The Radeon 860M, by contrast, sits at the 72nd percentile, indicating that it outperforms a substantially larger share of the GPU population.

The Radeon 860M wins on every measurable compute metric. Its FP32 throughput is 3.072 TFLOPS, which is nearly double the 1.638 TFLOPS of the Ryzen Z2 A GPU. That gap translates directly into faster shader processing, higher pixel throughput, and higher texture throughput. The Radeon 860M delivers 48.00 GPixel/s of pixel fill rate versus 25.60 GPixel/s for the Ryzen Z2 A GPU, a margin of roughly 88%. Texture fill rate follows the same pattern: 96.00 GTexel/s versus 51.20 GTexel/s, again nearly double.

In actual recorded benchmarks, the Radeon 860M posts a Geekbench OpenCL score of 22759 and a Geekbench Vulkan score of 30043. The Ryzen Z2 A GPU has no entries in the benchmark database, meaning there is no directly recorded score to compare. The architecture gap is the primary reason: RDNA 3.5 on a 4 nm process versus RDNA 2.0 on a 7 nm process. The newer architecture and denser process node give the Radeon 860M a fundamental efficiency and throughput advantage.

Where the Ryzen Z2 A GPU does win is in memory capacity. It carries 16 GB of LPDDR5 memory on a 128 bit bus, with 102.4 GB/s of dedicated bandwidth and a fixed 800 MHz memory clock at 6.4 Gbps effective. The Radeon 860M uses system shared memory, meaning its bandwidth is system dependent and its memory size is whatever the host system allocates. For workloads that require large data sets resident in memory, the Ryzen Z2 A GPU has the advantage of a fixed, generous pool. The Radeon 860M must rely on the host system's memory configuration, which can vary.

The Ryzen Z2 A GPU also has a higher base clock, 1000 MHz versus 600 MHz, but its boost clock is far lower at 1600 MHz versus 3000 MHz. That clock profile suggests the Ryzen Z2 A GPU is tuned for sustained, lower-frequency operation, while the Radeon 860M is designed to scale much higher under load. In practice, the Radeon 860M's boost advantage of 1400 MHz explains much of its compute lead.

Architecture Differences

The two GPUs come from different architectural generations and different process nodes. The Radeon 860M is built on RDNA 3.5, uses the Krackan Point chip, and is fabricated on a 4 nm process at TSMC. The Ryzen Z2 A GPU uses RDNA 2.0, is based on the Van Gogh chip, and is fabricated on a 7 nm process, also at TSMC. The process node difference is significant: 4 nm versus 7 nm, which allows the Radeon 860M to pack more transistors per area and operate at higher clocks within the same power envelope.

Transistor data highlights the density difference. The Ryzen Z2 A GPU has 2,400 million transistors on a 163 mm² die, yielding a transistor density of 14.7 million transistors per mm². The Radeon 860M's transistor count and die size are listed as unknown in the database, so a direct density comparison is not possible. However, the process node advantage alone points to a materially denser design.

Both GPUs share the same shading unit count: 512 shading units, 32 texture mapping units, 16 render output units, and 8 ray tracing cores. The core configuration is identical. The difference lies in how those cores are clocked and how the architecture executes instructions. RDNA 3.5 delivers higher instruction-level efficiency per clock than RDNA 2.0, and the recorded FP16 behavior illustrates an architectural divergence. The Radeon 860M runs FP16 at 3.072 TFLOPS at a 1:1 ratio with FP32, meaning it does not double throughput for half-precision work. The Ryzen Z2 A GPU runs FP16 at 3.277 TFLOPS at a 2:1 ratio, meaning it processes half-precision at twice the rate of FP32. For workloads that use FP16 heavily, the Ryzen Z2 A GPU's FP16 throughput actually exceeds its FP32 throughput, while the Radeon 860M treats both equally.

Clock behavior also differs sharply. The Radeon 860M has a base clock of 600 MHz and a boost clock of 3000 MHz, a 5x scaling range. The Ryzen Z2 A GPU has a base clock of 1000 MHz and a boost clock of 1600 MHz, a much narrower range. The higher boost clock on the Radeon 860M is the single largest contributor to its performance lead in the recorded benchmarks.

Memory architecture is another major differentiator. The Radeon 860M relies on system shared memory with system dependent bandwidth, while the Ryzen Z2 A GPU has dedicated 16 GB of LPDDR5 on a 128 bit bus with 102.4 GB/s bandwidth. The Ryzen Z2 A GPU also lists a fixed memory clock of 800 MHz with 6.4 Gbps effective, while the Radeon 860M's memory clock is simply listed as system shared.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API feature coverage is identical. The Radeon 860M uses a PCIe 4.0 x8 bus interface, while the Ryzen Z2 A GPU lists no bus interface data. Display output differs as well: the Radeon 860M is portable device dependent, while the Ryzen Z2 A GPU lists a single USB Type-C output.

Power characteristics are listed identically at 15 W TDP for both, though the Radeon 860M is an integrated graphics processor with no power connectors, while the Ryzen Z2 A GPU has no slot width, power connector, or suggested PSU data recorded. The Radeon 860M also carries a release date of 2025-02-28, while the Ryzen Z2 A GPU was released on 2024-12-31, roughly two months earlier. The Radeon 860M belongs to the Navi III IGP (Strix Point Mobile) generation, while the Ryzen Z2 A GPU is classified as a Console GPU (AMD) generation.

The Ryzen Z2 A GPU sits at the 50th percentile with no recorded scores, so any direct comparison relies on the Radeon 860M's measured results and the architectural specifications of both parts.

The nearest rivals to the Radeon 860M provide context for its position. The NVIDIA GeForce MX550 has an average score of 26421, a delta of -0.1% relative to the Radeon 860M, meaning the two are effectively tied. The NVIDIA GeForce RTX 5060 scores 26331, a delta of 0.3%, also effectively tied. The AMD Radeon RX 5700 XT 50th Anniversary scores 26553, a delta of -0.6%. The NVIDIA RTX A4000 scores 26683, a delta of -1.1%. The Radeon 860M sits within a narrow band of roughly 1% of these four rivals, indicating that its compute performance is competitive with a range of discrete and professional GPUs despite being an integrated part.

The biggest wins for the Radeon 860M come in raw throughput metrics. Its FP32 throughput of 3.072 TFLOPS is 1.434 TFLOPS higher than the Ryzen Z2 A GPU's 1.638 TFLOPS, a lead of roughly 88%. Pixel rate is 22.40 GPixel/s higher, and texture rate is 44.80 GTexel/s higher. The boost clock advantage is 1400 MHz, and the Radeon 860M's 3000 MHz boost is nearly double the Ryzen Z2 A GPU's 1600 MHz boost. The combination of a newer architecture and a smaller process node explains why the Radeon 860M achieves these results within the same 15 W TDP.

The Ryzen Z2 A GPU's wins are narrower but real. Its FP16 throughput of 3.277 TFLOPS exceeds the Radeon 860M's 3.072 TFLOPS, a 0.205 TFLOPS advantage, because it runs FP16 at a 2:1 ratio while the Radeon 860M runs it at 1:1. Its 16 GB of LPDDR5 memory with 102.4 GB/s bandwidth is a fixed allocation, whereas the Radeon 860M's memory capacity and bandwidth depend entirely on the host system. Its base clock of 1000 MHz is 400 MHz higher than the Radeon 860M's 600 MHz base, though that advantage disappears under boost. The Ryzen Z2 A GPU also has a higher transistor count on record, 2,400 million versus unknown for the Radeon 860M, and a known die size of 163 mm².

The overall picture from the recorded data is one-sided on compute. The Radeon 860M leads in every recorded benchmark and most throughput metrics, while the Ryzen Z2 A GPU offers a larger fixed memory pool and higher FP16 throughput. The Radeon 860M's 72nd percentile ranking versus the Ryzen Z2 A GPU's 50th percentile ranking confirms that the former is the stronger performer in the database's overall GPU distribution. The Ryzen Z2 A GPU's lack of recorded benchmark scores means its real-world performance cannot be validated against the Radeon 860M's measured results.
