AMD Ryzen Z2 GPU vs Intel Iris Xe Graphics 80EU Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark results between the AMD Ryzen Z2 GPU and the Intel Iris Xe Graphics 80EU Mobile. Both entries carry empty benchmark arrays, zero average benchmark scores, and identical percentile placements at the 50th percentile among all GPUs in the database. The absence of measured performance data means the comparison must be drawn from the architectural specifications and derived throughput figures available in the database.

The most decisive advantage for the AMD Ryzen Z2 GPU appears in raw compute throughput. The database records the AMD part at 8.294 TFLOPS FP32 performance, while the Intel Iris Xe Graphics 80EU Mobile delivers 1.856 TFLOPS FP32. That places the AMD GPU roughly 4.5 times ahead in single-precision floating-point work, a margin that dominates any workload relying on shader math. The FP16 comparison tells a different structural story: the AMD GPU maintains a 1:1 FP16 to FP32 ratio at 8.294 TFLOPS, whereas the Intel part runs FP16 at 3.712 TFLOPS via a 2:1 ratio. Even with Intel's doubled FP16 rate relative to its own FP32, the AMD GPU still leads by a factor of approximately 2.2 in half-precision throughput.

Texture and pixel fill rates follow the same pattern. The AMD Ryzen Z2 GPU records a texture rate of 129.6 GTexel/s against Intel's 58.00 GTexel/s, a lead of roughly 2.2 times. Pixel throughput shows an even wider gap: 86.40 GPixel/s for AMD versus 29.00 GPixel/s for Intel, a 3.0 times advantage. Those derived rates come from the respective shading unit, TMU, and ROP counts combined with clock speeds, so they reflect the hardware's designed capacity rather than any application-specific measurement.

Clock behavior also favors the AMD part. The Ryzen Z2 GPU runs a base clock of 800 MHz and a boost clock of 2700 MHz. The Intel Iris Xe Graphics 80EU Mobile starts at a 300 MHz base and boosts to 1450 MHz. The boost ceiling alone gives AMD a 1.86 times higher maximum clock. Memory configuration reinforces the gap: the AMD GPU accesses 16 GB of LPDDR5X over a 128 bit bus at 119.9 GB/s, while the Intel part uses System Shared memory with System Dependent bandwidth. The database does not quantify Intel's achievable bandwidth, but the fixed 119.9 GB/s figure for AMD provides a concrete reference point.

Where Each One Wins

The AMD Ryzen Z2 GPU wins in every category where the database provides a quantifiable specification. Its 768 shading units outnumber Intel's 640, its 48 TMUs exceed Intel's 40, and its 32 ROPs double Intel's 20. The AMD part also includes 12 ray tracing cores, a feature entirely absent from the Intel Iris Xe Graphics 80EU Mobile entry, which lists no RT core count. For workloads that use DirectX 12 Ultimate features, AMD supports the 12_2 feature level while Intel's entry stops at DirectX 12 (12_1). That difference matters for ray-traced effects and other advanced rendering paths that require the 12_2 feature set.

The Intel Iris Xe Graphics 80EU Mobile wins only in the narrow sense of power envelope and form factor. Its TDP is recorded at 15 W, compared to 28 W for the AMD Ryzen Z2 GPU. The Intel part is an IGP with a Ring Bus interface and display outputs described as Portable Device Dependent, meaning it is designed for integration into mobile systems where the host platform determines connectivity. The AMD GPU lists a single USB Type-C display output and no power connectors, but its higher TDP and separate chip designation suggest a different integration path.

FP16 workloads present the one area where Intel's architecture shows a relative strength, even though it still loses the absolute race. Intel's 2:1 FP16 to FP32 ratio means the Iris Xe can process half-precision data at double its FP32 rate, reaching 3.712 TFLOPS. The AMD GPU's 1:1 ratio means it treats FP16 and FP32 identically at 8.294 TFLOPS. Applications that can exploit FP16 acceleration would see Intel close the gap from 4.5 times behind to roughly 2.2 times behind, but AMD retains the outright lead.

Architecture Differences

The AMD Ryzen Z2 GPU uses the RDNA 3.0 architecture on a Hawk Point chip fabricated at TSMC on a 4 nm process. The database records 25,390 million transistors on a 178 mm² die, yielding a transistor density of 142.6 million transistors per square millimeter. The Intel Iris Xe Graphics 80EU Mobile belongs to the Generation 12.2 architecture, built on a Raptor Lake chip at Intel's 10 nm process. No transistor count, die size, or density figure is recorded for the Intel part, which prevents a direct manufacturing comparison.

Memory architecture differs fundamentally between the two. AMD pairs the Ryzen Z2 GPU with 16 GB of dedicated LPDDR5X memory on a 128 bit bus, delivering 119.9 GB/s of bandwidth at a memory clock of 937 MHz (7.5 Gbps effective). Intel's Iris Xe Graphics 80EU Mobile has no dedicated memory: all memory fields read System Shared, with bandwidth marked System Dependent. That means the Intel GPU's memory performance varies with the host system's RAM configuration, while the AMD GPU has a fixed, predictable memory subsystem.

The compute pipeline layouts diverge in both scale and capability. AMD fields 768 shading units, 48 TMUs, 32 ROPs, and 12 ray tracing cores. Intel fields 640 shading units, 40 TMUs, and 20 ROPs, with no ray tracing cores listed. The API support also differs: AMD lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while Intel lists DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. Both support the same OpenGL and Vulkan versions, but the DirectX feature level split is meaningful for modern game titles.

Power and integration design separate the two as well. The AMD Ryzen Z2 GPU carries a 28 W TDP and no power connectors, while the Intel Iris Xe Graphics 80EU Mobile carries a 15 W TDP and is explicitly marked as an IGP with a Ring Bus interface. The Intel part's successor is listed as Arc Graphics-M, indicating the product line's direction. The AMD part has no listed predecessor or successor. Release timing differs by roughly one year: Intel's entry is dated January 2024, while AMD's is dated December 2024 (the database records Intel's release date as 2023-01-03 and AMD's as 2024-12-31 in UTC terms). Both are marked Active in production status.

The Verdict

The data points to a clear segmentation rather than a direct competition. The AMD Ryzen Z2 GPU delivers roughly 4.5 times the FP32 throughput, 2.2 times the texture rate, and 3.0 times the pixel rate of the Intel Iris Xe Graphics 80EU Mobile, with dedicated 16 GB LPDDR5X memory at 119.9 GB/s and 12 ray tracing cores. Any user whose workload depends on shader compute, texture filtering, pixel fill, or ray tracing should select the AMD part based on these recorded specifications.

The Intel Iris Xe Graphics 80EU Mobile occupies the low-power integrated segment. Its 15 W TDP, IGP classification, Ring Bus interface, and system-shared memory make it appropriate for compact portable systems where the 28 W AMD GPU would require more thermal and power headroom. The Intel part also benefits from its FP16 2:1 ratio, which allows half-precision work at double its FP32 rate, though it still trails AMD's absolute FP16 output.

The percentile ranking provides no differentiation: both GPUs sit at the 50th percentile among all GPUs in the database, and both carry an average benchmark score of zero. The recorded data therefore cannot support a performance ranking from real-world tests. The verdict rests entirely on the architectural specifications, which favor AMD decisively in throughput and features, and favor Intel only in power draw and integration flexibility.
