AMD Radeon 860M vs AMD Ryzen Z1 GPU Comparison

Where Each One Wins

The benchmark data splits cleanly between these two AMD integrated graphics solutions, but only one of them has recorded measurements in the database. The AMD Radeon 860M carries two benchmark results: a Geekbench OpenCL score of 22,759 and a Geekbench Vulkan score of 30,043. Its average benchmark score sits at 26,401, placing it in the 72nd percentile among all GPUs tracked by the database. The AMD Ryzen Z1 GPU, by contrast, has no recorded benchmark scores, no average score, and no nearest rivals listed. Its percentile ranking is 50, which reflects a mid-pack position relative to the broader GPU pool, but without direct measurements, the data cannot confirm where it wins or loses in specific workloads.

What the data does show is that the Radeon 860M's Vulkan result (30,043) is substantially higher than its OpenCL result (22,759), a gap of roughly 7,284 points. That disparity suggests the RDNA 3.5 architecture in the 860M responds more favorably to Vulkan's lower-level API overhead. The OpenCL score, while lower, still lands near the average of 26,401, meaning the OpenCL workload pulls the average down from the Vulkan peak. For the Ryzen Z1 GPU, the absence of benchmark entries means no use-case split can be derived from measurements. The database records no wins for either part in the head-to-head section, so any comparison of workload-specific strengths must rely on architectural and specification differences rather than direct test results.

Architecture Differences

The two GPUs come from different AMD generations and use different RDNA revisions. The Radeon 860M is built on the Krackan Point chip, uses RDNA 3.5, and belongs to the Navi III IGP generation for Strix Point Mobile. It is fabricated on a 4 nm process at TSMC, though its transistor count, die size, and transistor density are listed as unknown. The Ryzen Z1 GPU uses the Phoenix chip with RDNA 3.0 and is categorized as a Console GPU. It is also fabricated on a 4 nm process at TSMC, but the database provides full silicon details: 25,390 million transistors on a 178 mm² die, for a transistor density of 142.6 million per mm².

The execution resources differ significantly. The Radeon 860M carries 512 shading units, 32 texture mapping units, 16 render output units, and 8 ray tracing cores. The Ryzen Z1 GPU has half of each: 256 shading units, 16 TMUs, 8 ROPs, and 4 ray tracing cores. These are direct halving relationships, which indicate the 860M has double the raw shader throughput and texture/ROP capability on paper. Clock behavior also diverges. The 860M runs a 600 MHz base clock and boosts to 3000 MHz. The Ryzen Z1 GPU starts at 1500 MHz base and boosts to 2500 MHz. The higher base clock on the Z1 GPU suggests better sustained low-load performance, while the 860M's higher boost ceiling provides more headroom under full load.

Memory architecture separates the two as well. The Radeon 860M uses system-shared memory with a system-dependent bandwidth and no dedicated VRAM allocation. The Ryzen Z1 GPU has a fixed 16 GB of LPDDR5 memory on a 64-bit bus, delivering 51.20 GB/s of bandwidth and running at 800 MHz with 6.4 Gbps effective speed. The Z1 GPU also lists physical dimensions (280 mm by 111 mm by 21 mm), whereas the 860M reports no dimensions. The 860M connects via PCIe 4.0 x8, while the Z1 GPU has no bus interface listed. Display outputs also differ: the 860M is portable-device dependent, while the Z1 GPU has no outputs at all.

Compute throughput numbers reflect the architectural split. The Radeon 860M reaches 3.072 TFLOPS FP32 and 3.072 TFLOPS FP16 at a 1:1 ratio. The Ryzen Z1 GPU delivers 2.560 TFLOPS FP32 but 5.120 TFLOPS FP16 at a 2:1 ratio. That FP16 advantage for the Z1 GPU is notable because it suggests the Phoenix chip processes half-precision math at twice the rate of single-precision, whereas the 860M treats both at the same rate. Pixel and texture rates follow the shader counts: the 860M produces 48.00 GPixel/s and 96.00 GTexel/s, while the Z1 GPU produces 20.00 GPixel/s and 40.00 GTexel/s.

Power targets also differ. The Radeon 860M has a 15 W TDP, while the Ryzen Z1 GPU has a 30 W TDP. Both use no power connectors. The 860M is an IGP with no slot width, while the Z1 GPU's slot width is not recorded. API support is identical: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The 860M was released on 2025-02-28, and the Z1 GPU on 2023-09-17. The 860M's predecessor is Navi II IGP, while the Z1 GPU has no predecessor listed. The 860M has an active production status, as does the Z1 GPU.

The Verdict

The recorded data favors the AMD Radeon 860M in raw measured performance. Its average benchmark score of 26,401 places it at the 72nd percentile, and its nearest rivals cluster tightly around that average: the NVIDIA GeForce MX550 averages 26,421 (0.1% below the 860M), the AMD Radeon RX 5700 XT 50th Anniversary averages 26,553 (0.6% below), and the NVIDIA RTX A4000 averages 26,683 (1.1% below). The only rival with a higher average is the NVIDIA GeForce RTX 5060 at 26,331, which sits 0.3% above the 860M, a marginal edge within noise. The 860M's Vulkan score of 30,043 is particularly strong, indicating the part performs well above its average in Vulkan-heavy workloads.

The Ryzen Z1 GPU cannot be assessed on measured performance because the database contains no benchmark entries for it. Its 50th percentile ranking is a positional marker, not a test result. The architectural data shows the Z1 GPU has half the shading units, TMUs, ROPs, and ray tracing cores of the 860M, along with lower FP32 throughput (2.560 TFLOPS vs. 3.072 TFLOPS) and lower pixel/texture rates. It compensates with a higher base clock (1500 MHz vs. 600 MHz), dedicated 16 GB of LPDDR5 memory with 51.20 GB/s bandwidth, and a doubled FP16 rate (5.120 TFLOPS at 2:1). The Z1 GPU also carries a 30 W TDP versus 15 W for the 860M.

From the data alone, the Radeon 860M is the stronger measured performer with a higher average score, higher percentile, and more favorable nearest-rival positioning. The Ryzen Z1 GPU's advantages are structural: fixed memory, higher base clock, and a 2:1 FP16 ratio. The Z1 GPU also has a recorded launch MSRP of 599 USD, which the 860M does not have. For users prioritizing measured compute results, the 860M is the clear choice. For users needing a fixed 16 GB memory pool and half-precision throughput, the Z1 GPU offers those specific characteristics, but no benchmark data confirms its real-world standing.

Head-to-Head Benchmarks

The head-to-head benchmark section in the database is empty, with zero wins recorded for either GPU and no individual test entries. Direct comparisons on identical workloads are therefore not available. The closest proxy for the Radeon 860M's standing comes from its nearest rivals. The 860M's average score of 26,401 sits within a tight band of competitor averages: the NVIDIA GeForce MX550 at 26,421 (0.1% higher), the AMD Radeon RX 5700 XT 50th Anniversary at 26,553 (0.6% higher), and the NVIDIA RTX A4000 at 26,683 (1.1% higher). The NVIDIA GeForce RTX 5060 averages 26,331, which is 0.3% lower than the 860M. These deltas are all under 1.2%, indicating the 860M performs in a narrow competitive cluster rather than decisively above or below any single rival.

Within the 860M's own benchmark results, the Vulkan score of 30,043 exceeds the OpenCL score of 22,759 by 7,284 points, a 32% margin relative to the OpenCL result. That internal gap is larger than any inter-GPU delta in its rival list, which suggests the 860M's architecture has a pronounced API sensitivity. The OpenCL score of 22,759 falls below the database average of 26,401, while the Vulkan score rises above it. This means the 860M's average is pulled down by the OpenCL result and supported by the Vulkan result.

For the Ryzen Z1 GPU, no benchmark scores exist, so no head-to-head walkthrough is possible from measurements. The specification data offers the only comparative frame. The Z1 GPU's FP32 throughput of 2.560 TFLOPS is 0.512 TFLOPS lower than the 860M's 3.072 TFLOPS, a 16.7% deficit. Its pixel rate of 20.00 GPixel/s is 28.00 GPixel/s lower than the 860M's 48.00 GPixel/s, a 58.3% deficit. Its texture rate of 40.00 GTexel/s is 56.00 GTexel/s lower than the 860M's 96.00 GTexel/s, a 58.3% deficit. These are large gaps in the 860M's favor.

The Z1 GPU's counterpoints are its FP16 rate and memory configuration. Its 5.120 TFLOPS FP16 output is 2.048 TFLOPS higher than the 860M's 3.072 TFLOPS, a 66.7% advantage. Its fixed 16 GB LPDDR5 memory with 51.20 GB/s bandwidth is a defined specification, whereas the 860M's system-shared memory bandwidth is system dependent. The Z1 GPU's base clock of 1500 MHz is 900 MHz higher than the 860M's 600 MHz base, though its 2500 MHz boost is 500 MHz lower. These factors do not translate into measured wins because no tests were recorded, but they represent the only quantitative comparison points available.
