AMD Ryzen Z1 GPU vs Intel Arc Graphics 4 Xe Mobile Comparison

Head-to-Head Benchmarks

The recorded data for both the AMD Ryzen Z1 GPU and the Intel Arc Graphics 4 Xe Mobile contains no benchmark scores, no win counts, and no comparison metrics. The database shows an empty head-to-head benchmark table, with zero wins for either part. The average benchmark score for each is listed as 0, and both hold a 50th percentile position among all GPUs. Without measured performance data, a direct numerical comparison of frame rates, compute workloads, or synthetic tests is not possible from the available records.

What can be established from the database is the theoretical peak throughput, which is derived from clock speeds and core counts. The AMD Ryzen Z1 GPU delivers 2.560 TFLOPS of FP32 compute, while the Intel Arc Graphics 4 Xe Mobile provides 2.355 TFLOPS. This puts the AMD part roughly 8.7% ahead in raw single-precision floating-point throughput. In FP16, the AMD GPU reaches 5.120 TFLOPS versus 4.710 TFLOPS for the Intel part, again a modest advantage for AMD.

Texture and pixel fill rates tell a different story. The Intel Arc Graphics 4 Xe Mobile records a texture rate of 73.60 GTexel/s, which is 84% higher than the AMD Ryzen Z1 GPU's 40.00 GTexel/s. Pixel throughput similarly favors Intel: 36.80 GPixel/s versus 20.00 GPixel/s, a 84% lead. These figures indicate that the Intel part has a substantially higher capacity for texture-heavy and fill-limited workloads, despite its lower FP32 peak.

Clock behavior also differs. The AMD Ryzen Z1 GPU runs at a base clock of 1500 MHz and boosts to 2500 MHz. The Intel Arc Graphics 4 Xe Mobile has a much lower base of 300 MHz but a boost of 2300 MHz. The AMD part holds a 200 MHz advantage at boost, but the Intel part's core count compensates in throughput metrics.

Memory bandwidth is firmly in AMD's favor. The Ryzen Z1 GPU uses 16 GB of LPDDR5 on a 64-bit bus, yielding 51.20 GB/s. The Intel Arc Graphics 4 Xe Mobile relies on system shared memory with system dependent bandwidth, so no fixed number exists for comparison. The database records the Intel memory bandwidth as "System Dependent", which means it cannot be directly compared to the AMD figure.

Architecture Differences

The AMD Ryzen Z1 GPU is built on the Phoenix chip using the RDNA 3.0 architecture, fabricated on a 4 nm process at TSMC. The Intel Arc Graphics 4 Xe Mobile uses the Panther Lake chip with the Xe3-LPG architecture, fabricated on a 3 nm process at Intel. The process node difference gives Intel a smaller geometry, but the database does not provide transistor counts or die size for the Intel part, so density comparisons are impossible.

Core configuration diverges sharply. The AMD part has 256 shading units, 16 texture mapping units, 8 render output units, and 4 ray tracing cores. The Intel part doubles the shading units to 512, doubles TMUs to 32, doubles ROPs to 16, and also has 4 ray tracing cores. The Intel architecture thus allocates more execution resources to texture and pixel processing, which matches its higher fill rates.

Memory architecture is another fundamental difference. The AMD Ryzen Z1 GPU uses dedicated 16 GB of LPDDR5 memory with a 64-bit bus and fixed 51.20 GB/s bandwidth. The Intel Arc Graphics 4 Xe Mobile uses system shared memory, with type, bus width, and bandwidth all listed as system dependent. This means the Intel part's memory performance varies with the host system configuration, while AMD's is fixed.

Power consumption differs as well. The AMD Ryzen Z1 GPU has a TDP of 30 W, while the Intel Arc Graphics 4 Xe Mobile has a TDP of 25 W. The Intel part uses 5 W less, which may be relevant for thermally constrained mobile designs.

Form factor and outputs also distinguish the two. The AMD Ryzen Z1 GPU is a discrete-style component with dimensions of 280 mm length, 111 mm height, and 21 mm width, and it has no display outputs. The Intel Arc Graphics 4 Xe Mobile is an integrated graphics processor (IGP) with no listed dimensions and display outputs that are portable device dependent. Neither uses external power connectors.

Release timing is notably different. The AMD Ryzen Z1 GPU launched on September 17, 2023, with a launch MSRP of 599 USD. The Intel Arc Graphics 4 Xe Mobile has a release date of January 26, 2026, and no launch MSRP is recorded.

The Verdict

The data presents two different design philosophies. The AMD Ryzen Z1 GPU prioritizes higher FP32 compute, dedicated memory bandwidth, and a higher boost clock. The Intel Arc Graphics 4 Xe Mobile prioritizes core count, texture throughput, pixel fill rates, and lower power draw.

For compute-bound workloads that rely on raw floating-point performance, the AMD part holds a measurable lead: 2.560 TFLOPS versus 2.355 TFLOPS in FP32, and 5.120 versus 4.710 TFLOPS in FP16. The dedicated 51.20 GB/s of LPDDR5 bandwidth also gives AMD a fixed memory advantage over Intel's system dependent shared memory.

For graphics workloads that are heavy on texturing and pixel shading, the Intel part is clearly superior on paper. Its 84% advantage in both texture rate and pixel rate, combined with double the shading units, TMUs, and ROPs, indicates stronger throughput for fill-limited scenes. The lower 25 W TDP also makes it more power-efficient in absolute terms.

The lack of any benchmark scores means these theoretical metrics cannot be confirmed in real-world performance. The database records no wins for either side. What is certain is that the AMD Ryzen Z1 GPU is a discrete component with a fixed memory subsystem and a specific launch MSRP of 599 USD. The Intel Arc Graphics 4 Xe Mobile is an integrated solution whose performance depends on the host system's memory.

Architecturally, the AMD part uses RDNA 3.0 on a 4 nm TSMC process, while the Intel part uses Xe3-LPG on a 3 nm Intel process. The Intel part is newer by release date, but the database does not indicate whether that translates into a performance advantage.

Selection between these two depends on workload priorities. For FP32 compute and fixed memory bandwidth, the AMD Ryzen Z1 GPU is the data-supported choice. For texture and pixel throughput with lower power consumption, the Intel Arc Graphics 4 Xe Mobile is the data-supported choice. Without benchmark results, neither can be declared an overall winner.
