AMD Ryzen Z2 GPU vs Intel Arc Graphics 128EU Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows no direct benchmark scores for either AMD Ryzen Z2 GPU or Intel Arc Graphics 128EU Mobile. Both entries list zero benchmark results, zero wins in head-to-head comparisons, and zero average benchmark scores. The absence of measured data means the comparison must rely entirely on architectural specifications and computed throughput rates.

The FP32 compute figures show a clear gap. AMD Ryzen Z2 GPU delivers 8.294 TFLOPS, while Intel Arc Graphics 128EU Mobile delivers 4.608 TFLOPS. That places the AMD part at roughly 80% higher raw single-precision throughput. FP16 shifts the picture: AMD lists 8.294 TFLOPS with a 1:1 ratio, while Intel lists 9.216 TFLOPS with a 2:1 ratio. The Intel part has a faster FP16 path, exceeding AMD by about 11%, but AMD matches its FP32 rate exactly in FP16, which suggests a unified shader approach without dedicated half-rate execution.

Texture throughput favors Intel. The Arc Graphics 128EU Mobile reaches 144.0 GTexel/s, versus 129.6 GTexel/s for the Ryzen Z2 GPU. That is an 11% advantage for Intel in texture fill. Pixel throughput favors AMD. The Ryzen Z2 GPU reaches 86.40 GPixel/s, versus 72.00 GPixel/s for the Intel part, a 20% advantage for AMD in raster fill.

Clock behavior differs substantially. The AMD part runs a base clock of 800 MHz and a boost clock of 2700 MHz. Intel runs a base clock of 300 MHz and a boost clock of 2250 MHz. The AMD boost clock is 20% higher, and the base clock is significantly higher. Memory bandwidth is not comparable because Intel uses system shared memory with system-dependent bandwidth. The AMD part has dedicated LPDDR5X memory at 119.9 GB/s.

Both parts occupy the same 28 W TDP envelope. That makes the performance differences purely architectural and efficiency driven, not power budget driven.

Architecture Differences

The AMD Ryzen Z2 GPU is built on the Hawk Point chip with RDNA 3.0 architecture. Intel Arc Graphics 128EU Mobile uses the Meteor Lake chip with Xe-LPG architecture. The process nodes diverge: AMD uses a 4 nm TSMC process, while Intel uses a 10 nm Intel process. AMD lists 25,390 million transistors on a 178 mm² die, giving a transistor density of 142.6M per mm². Intel does not list transistor count or die size in the database.

Shader resources differ. AMD has 768 shading units, 48 TMUs, and 32 ROPs. Intel has 1024 shading units, 64 TMUs, and 32 ROPs. Intel holds a 33% advantage in shading units and a 33% advantage in TMUs, while ROP counts match at 32. Despite fewer shading units, AMD achieves higher FP32 throughput because of the RDNA 3.0 architecture's execution efficiency and higher clocks. Ray tracing support differs: AMD lists 12 RT cores, while Intel lists no RT core count. Both support DirectX 12 Ultimate, but AMD lists 12 Ultimate (12_2) while Intel lists only 12 (12_1). Vulkan support matches at 1.4, OpenGL matches at 4.6.

Memory architecture is fundamentally different. AMD uses 16 GB of LPDDR5X on a 128 bit bus with 119.9 GB/s bandwidth and a memory clock of 937 MHz (7.5 Gbps effective). Intel uses system shared memory with system-dependent bandwidth and no dedicated VRAM. This affects both capacity and latency characteristics, though the database records no latency measurements.

Clock ratios matter. AMD runs FP16 at the same rate as FP32 (1:1), which is typical for RDNA 3.0. Intel runs FP16 at double the FP32 rate (2:1), which is typical for Xe-LPG. The result is that Intel's FP16 output exceeds AMD's despite lower FP32 output. The bus interface differs: Intel uses a Ring Bus, while AMD lists no bus interface. Display outputs differ: AMD lists 1x USB Type-C, while Intel lists portable device dependent outputs. Power connectors differ: AMD lists none, Intel lists none as well.

The Verdict

The data indicates two different design philosophies. AMD Ryzen Z2 GPU targets sustained compute throughput in a fixed power envelope, using a 4 nm process, dedicated memory, and fewer but faster shader units. Intel Arc Graphics 128EU Mobile targets flexibility through system shared memory, a larger shader array, and higher FP16 throughput.

For FP32 workloads, the AMD part is the stronger choice. It delivers 8.294 TFLOPS versus 4.608 TFLOPS, a 79.9% advantage. For FP16 workloads, Intel takes the lead at 9.216 TFLOPS versus 8.294 TFLOPS, an 11.1% advantage. For texture-heavy workloads, Intel leads with 144.0 GTexel/s versus 129.6 GTexel/s. For pixel-heavy workloads, AMD leads with 86.40 GPixel/s versus 72.00 GPixel/s.

The 28 W TDP is identical. Both parts are active in production. AMD released on 2024-12-31, Intel released on 2023-12-13. Intel has a predecessor listed (HD Graphics-M), AMD has none. Neither lists a successor.

The percentile versus all GPUs is 50 for both, which places both in the middle of the database distribution. No nearest rivals are listed for either part, so no external comparison points exist.
