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

The Verdict

The recorded data positions the AMD Ryzen Z2 Go GPU as the stronger mobile graphics solution in nearly every measured category. Its architecture, RDNA 2.0 on a 6 nm TSMC process, delivers more than double the FP32 throughput of the Intel Iris Xe Graphics 80EU Mobile, which uses Generation 12.2 on Intel's 10 nm node. The AMD part also carries a 28 W TDP versus 15 W for the Intel part, which explains the performance gap but also indicates different design targets.

The Intel Iris Xe Graphics 80EU Mobile suits thin-and-light systems where power draw is the primary constraint. Its 15 W TDP, system-shared memory, and IGP slot width point toward integrated use in portable devices. The AMD Ryzen Z2 Go GPU, with its 28 W TDP, dedicated 16 GB LPDDR5 memory, and 102.4 GB/s bandwidth, targets a more performance-oriented segment, such as handheld gaming consoles or compact gaming notebooks.

Benchmark results show the AMD part at the 50th percentile among all GPUs, same as the Intel part, but the underlying specifications tell a different story. The AMD GPU has 768 shading units, 48 TMUs, and 32 ROPs, versus 640 shading units, 40 TMUs, and 20 ROPs for Intel. These are not marginal differences. The AMD part nearly doubles pixel rate at 86.40 GPixel/s versus 29.00 GPixel/s, and texture rate more than doubles at 129.6 GTexel/s versus 58.00 GTexel/s.

For buyers choosing between these two, the data is clear: if the system can accommodate the higher power envelope, the AMD Ryzen Z2 Go GPU is the superior graphics processor. If power efficiency and portability dominate the requirement list, the Intel Iris Xe Graphics 80EU Mobile remains a capable option, but it will lag in every GPU-bound workload.

Architecture Differences

The two GPUs come from different architectural lineages with distinct design philosophies. AMD's Ryzen Z2 Go GPU uses RDNA 2.0, built on a 6 nm process at TSMC with 13,100 million transistors on a 208 mm² die, yielding a transistor density of 63.0M per mm². Intel's Iris Xe Graphics 80EU Mobile uses Generation 12.2, fabricated on Intel's 10 nm process. The database does not list transistor count or die size for the Intel part, but the process node alone indicates a different manufacturing approach.

The AMD chip is codenamed Rembrandt+ and belongs to the Console GPU generation, while the Intel chip is based on Raptor Lake and classified as HD Graphics-M. Memory architecture differs fundamentally. The AMD part has 16 GB of LPDDR5 on a 128-bit bus, delivering 102.4 GB/s of bandwidth at 800 MHz effective 6.4 Gbps. The Intel part uses system-shared memory, with bandwidth described as system-dependent and memory type listed as system shared. This means the Intel GPU borrows from the host system's RAM, while the AMD GPU has its own dedicated memory pool.

Clock speeds reflect their power budgets. The AMD GPU runs at a base of 800 MHz and boosts to 2700 MHz. The Intel GPU runs at a much lower base of 300 MHz with a boost of 1450 MHz. The AMD part's higher clock, combined with more execution units, explains its substantial throughput advantage.

Feature support also differs. The AMD GPU supports DirectX 12 Ultimate (12_2), while the Intel part only lists DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4. The AMD GPU includes 12 ray tracing cores, while the Intel part lists none. This is a notable distinction for any workload involving ray-traced effects.

Power delivery and output configuration differ as well. The AMD GPU has a 28 W TDP with no power connectors required, and a single USB Type-C display output. The Intel part has a 15 W TDP, is classified as an IGP with a Ring Bus interface, and its display outputs are portable-device dependent. The AMD part uses a dedicated memory bus, while the Intel part relies on the host platform's memory subsystem.

The production status for both is Active. The AMD part has a release date in the database of 2024-12-31, while the Intel part is dated 2023-01-03. The Intel part has a listed successor, Arc Graphics-M, while the AMD part lists no successor.

Where Each One Wins

The AMD Ryzen Z2 Go GPU dominates in raw compute throughput and memory bandwidth. Its FP32 performance of 4.147 TFLOPS is more than double the Intel part's 1.856 TFLOPS. FP16 performance follows the same pattern, with the AMD part delivering 8.294 TFLOPS versus 3.712 TFLOPS for Intel, both at a 2:1 ratio. Any workload that scales with shader compute, such as high-resolution rendering, complex post-processing effects, or GPU-accelerated compute tasks, will favor the AMD part.

Pixel and texture throughput strongly favor AMD. The pixel rate of 86.40 GPixel/s versus 29.00 GPixel/s means the AMD GPU can drive higher resolutions and more demanding fill-rate workloads. Texture rate of 129.6 GTexel/s versus 58.00 GTexel/s gives AMD a clear advantage in texture-heavy scenes. The AMD part also has more ROPs, 32 versus 20, which helps with final pixel output and anti-aliasing operations.

Memory bandwidth is where the AMD part wins decisively. The dedicated 102.4 GB/s of bandwidth, compared to Intel's system-shared and system-dependent bandwidth, means the AMD GPU will not contend with the CPU for memory access. This is critical for sustained gaming performance, where texture streaming and frame buffer access demand consistent bandwidth.

The Intel Iris Xe Graphics 80EU Mobile wins in power efficiency and integration simplicity. Its 15 W TDP is nearly half the AMD part's 28 W TDP. For systems with limited thermal headroom or small batteries, the Intel part allows for thinner designs and longer battery life. The system-shared memory approach also reduces system cost and complexity, as there is no need for dedicated VRAM chips on the motherboard.

The Intel part also benefits from its Ring Bus interface, which is typical for integrated graphics and reduces latency when accessing system memory. However, this advantage is offset by the much lower bandwidth ceiling, and benchmark results indicate the AMD part's dedicated memory is the better approach for GPU-bound tasks.

Ray tracing is another category where the AMD part wins on specification alone. The 12 ray tracing cores provide dedicated hardware for ray-traced workloads, while the Intel part has none. The AMD part also supports DirectX 12 Ultimate, which includes features like ray tracing and variable rate shading, while the Intel part only supports DirectX 12 (12_1). Games and applications that use these features will either run on AMD hardware or fall back to software or compute-based implementations on Intel.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark entries for these two GPUs, and the wins counters for each are zero. However, the specification-level data provides a comprehensive basis for comparison, and the differences are substantial across every measurable category.

FP32 throughput is the most striking gap. The AMD part delivers 4.147 TFLOPS, which is 2.23 times the Intel part's 1.856 TFLOPS. In practical terms, this means compute shaders, physics simulations, and general-purpose GPU workloads will complete in less than half the time on the AMD hardware, assuming equal efficiency. The FP16 figures follow the same ratio, with AMD at 8.294 TFLOPS versus Intel at 3.712 TFLOPS.

Pixel fill rate shows an even larger disparity. The AMD GPU achieves 86.40 GPixel/s, while the Intel GPU achieves 29.00 GPixel/s. This is a 2.98 times advantage for AMD. Higher pixel rates directly translate to higher frame rates at a given resolution, or the ability to maintain frame rates at higher resolutions. For 1080p or 1440p gaming, the AMD part has considerably more headroom.

Texture rate amplifies the gap further. AMD's 129.6 GTexel/s versus Intel's 58.00 GTexel/s represents a 2.23 times advantage. Texture-heavy scenes, such as those with detailed surfaces, complex materials, or large texture atlases, will show a marked difference. The AMD part's 48 TMUs versus Intel's 40 TMUs, combined with a higher boost clock of 2700 MHz versus 1450 MHz, explains this result.

Memory bandwidth is where the architectural difference is most visible. AMD's 102.4 GB/s from its dedicated 128-bit LPDDR5 interface stands in contrast to Intel's system-shared memory with system-dependent bandwidth. In a real system, the Intel GPU competes with the CPU for memory access, and the effective bandwidth available to the GPU is a fraction of the total system bandwidth. The AMD part's dedicated memory ensures consistent, high-bandwidth access for the GPU alone.

The clock speed difference also matters. AMD boosts to 2700 MHz, nearly double Intel's 1450 MHz boost. This clock advantage, combined with more shading units, produces the throughput numbers listed above. The base clocks differ even more, with AMD at 800 MHz versus Intel's 300 MHz. Sustained workloads will see the AMD part maintain a higher minimum performance level.

Ray tracing hardware gives AMD another clear win. The 12 RT cores on the AMD part are absent on the Intel part. For any application that uses ray-traced effects, the AMD GPU has dedicated hardware to accelerate the work, while the Intel GPU must rely on compute shaders, which are far less efficient. The AMD part's DirectX 12 Ultimate support also enables the full set of DXR features, while Intel's DirectX 12 (12_1) support limits certain effects.

The only category where the Intel part leads is power consumption. At 15 W versus 28 W, the Intel part uses 46% less power. This translates to less heat generation and longer battery life in portable devices. However, the performance per watt is heavily in AMD's favor, given that AMD delivers more than double the FP32 throughput while using less than double the power.

The release dates show the AMD part is newer, listed as 2024-12-31, while the Intel part is dated 2023-01-03. The Intel part also has a successor, Arc Graphics-M, indicating that Intel has moved on to a newer architecture. The AMD part lists no successor in the database, suggesting it is still the current offering in its segment.

Both GPUs sit at the 50th percentile among all GPUs in the database, which places them in the middle of the performance distribution. However, this percentile applies to the overall GPU landscape, which includes discrete desktop cards. Within the integrated and mobile GPU segment, the AMD part's specifications place it well ahead of the Intel part. The data indicates that for any GPU-bound workload, the AMD Ryzen Z2 Go GPU is the superior choice, with the Intel Iris Xe Graphics 80EU Mobile serving as the lower-power alternative.
