AMD Ryzen Z1 Extreme GPU vs Intel Arc Graphics 1 Xe Mobile Comparison

The AMD Ryzen Z1 Extreme GPU and the Intel Arc Graphics 1 Xe Mobile occupy different tiers of the mobile graphics landscape. The data indicates a decisive performance advantage for the AMD part across nearly every measurable compute and rendering metric, while the Intel solution focuses on efficiency and integration. This analysis compares the recorded specifications and architectural data for both processors.

Head-to-Head Benchmarks

The raw compute data shows a substantial gap between the two processors. The AMD Ryzen Z1 Extreme GPU delivers 8.294 TFLOPS of FP32 performance, while the Intel Arc Graphics 1 Xe Mobile delivers 588.8 GFLOPS. This places the AMD part at roughly 14 times the raw shader throughput of the Intel solution. The difference is equally pronounced in FP16 compute, where AMD records 16.59 TFLOPS (2:1) against Intel's 1,177.6 GFLOPS (2:1).

Pixel and texture processing follow the same pattern. The AMD processor achieves a pixel rate of 86.40 GPixel/s, compared to the Intel part's 9.200 GPixel/s. The texture rate for AMD is 129.6 GTexel/s, while Intel manages 18.40 GTexel/s. These figures indicate that the AMD GPU can fill frames and apply textures at a rate approximately 9 times and 7 times faster, respectively, than the Intel solution.

Clock speeds partially explain the compute disparity, though not entirely. The AMD chip has a base clock of 800 MHz and a boost clock of 2700 MHz. The Intel chip operates at a 300 MHz base clock and a 2300 MHz boost. The higher clock ceiling on the AMD side is paired with a considerably larger execution resource pool, which drives the majority of the performance gap.

Memory bandwidth is another significant differentiator. The AMD Ryzen Z1 Extreme GPU uses 16 GB of LPDDR5 memory on a 64 bit bus, yielding 51.20 GB/s of bandwidth. The Intel Arc Graphics 1 Xe Mobile relies on System Shared memory, with bandwidth listed as System Dependent. The recorded data shows no fixed bandwidth figure for the Intel part, meaning its memory throughput is contingent on the host platform. The AMD solution has a dedicated, quantified memory configuration that avoids this dependency.

Where Each One Wins

The AMD Ryzen Z1 Extreme GPU wins in every category where both parts have recorded numeric data. It is faster in FP32 compute, FP16 compute, pixel fill rate, texture fill rate, and memory bandwidth. Its 768 shading units, 48 texture mapping units, 32 ROPs, and 12 ray tracing cores dwarf the Intel part's 128 shading units, 8 TMUs, 4 ROPs, and 1 ray tracing core. The AMD GPU also has a higher TDP at 30 W, which allows for the sustained operation of its larger silicon.

The Intel Arc Graphics 1 Xe Mobile wins in the areas of physical integration and power draw. Its TDP is 25 W, which is lower than the AMD's 30 W by a modest margin. The Intel chip is fabricated on a 3 nm process node at Intel's foundry, compared to the AMD's 4 nm node at TSMC. The Intel part is an IGP (integrated graphics processor) with no separate slot width, power connectors, or bus interface beyond IGP. This means it requires no additional board space or power delivery beyond what the host system provides. The AMD part, while also lacking power connectors, is a discrete-style component with physical dimensions of 280 mm in length, 111 mm in height, and 21 mm in width.

The Intel part also has a later release date of 2026-04-15, compared to the AMD's 2023-06-12. The Intel processor has a predecessor in the HD Graphics-M line, while the AMD part has no recorded predecessor or successor. Both processors are listed as Active in production status.

Architecture Differences

The two GPUs come from different architectural lineages. The AMD Ryzen Z1 Extreme GPU uses the Phoenix chip based on RDNA 3.0 architecture. The Intel Arc Graphics 1 Xe Mobile uses the Wildcat Lake chip based on Xe3-LPG architecture. These are fundamentally different designs with different priorities.

The process nodes differ. AMD uses a 4 nm process at TSMC, while Intel uses a 3 nm process at its own foundry. The AMD chip contains 25,390 million transistors on a 178 mm² die, resulting in a transistor density of 142.6M per mm². The Intel chip's transistor count and die size are listed as unknown, so no direct density comparison is possible.

The execution resources are heavily skewed toward AMD. The AMD GPU has 768 shading units, 48 TMUs, 32 ROPs, and 12 RT cores. The Intel GPU has 128 shading units, 8 TMUs, 4 ROPs, and 1 RT core. This is a 6:1 ratio in shading units, a 6:1 ratio in TMUs, an 8:1 ratio in ROPs, and a 12:1 ratio in RT cores.

Memory architecture is another major divergence. The AMD part uses dedicated 16 GB of LPDDR5 memory with a 64 bit bus and a fixed 51.20 GB/s bandwidth. The Intel part uses System Shared memory, meaning it draws from the host system's RAM. Its bus width, memory type, and bandwidth are all System Dependent or System Shared, making its performance variable based on the surrounding hardware.

API support is identical. Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. This means both are capable of running the same modern graphics workloads from a software compatibility standpoint, though the AMD part does so with considerably more hardware throughput.

The display outputs differ. The AMD part has 1x USB Type-C output. The Intel part's display outputs are listed as Portable Device Dependent, meaning they vary by the device in which the chip is installed.

The Verdict

The data is unambiguous. The AMD Ryzen Z1 Extreme GPU is the faster processor in every recorded benchmark metric. Its FP32 performance of 8.294 TFLOPS against 588.8 GFLOPS, its pixel rate of 86.40 GPixel/s against 9.200 GPixel/s, and its texture rate of 129.6 GTexel/s against 18.40 GTexel/s establish a dominant performance tier. Its 16 GB of dedicated LPDDR5 memory with 51.20 GB/s bandwidth provides a stable, quantified memory subsystem that the Intel part cannot match due to its System Shared configuration.

The Intel Arc Graphics 1 Xe Mobile is the more integrated solution. It is an IGP with a 25 W TDP, a 3 nm process node, and no physical dimensions, slot width, or power connectors. It is designed to disappear into a host system, relying on shared memory and portable device dependent outputs. The AMD part is a physically larger component at 280 mm by 111 mm by 21 mm, with a 30 W TDP and a dedicated memory pool.

The launch MSRP for the AMD Ryzen Z1 Extreme GPU is 699 USD. The Intel part has no recorded launch MSRP.

Users who need raw graphics throughput for demanding workloads should select the AMD part. Users who prioritize a low-power, fully integrated graphics solution that requires no additional board space should select the Intel part. The performance gap is too large for the Intel part to serve as a substitute in compute-heavy scenarios, and the AMD part's size and power draw make it unsuitable for ultra-compact integrated designs.
