AMD Ryzen Z2 A GPU vs Intel Arc Graphics 64EU Mobile Comparison

The Verdict

The data compares two integrated graphics solutions, each built for different mobile design goals. The AMD Ryzen Z2 A GPU uses the RDNA 2.0 architecture on a 7 nm TSMC process, while the Intel Arc Graphics 64EU Mobile uses the Xe-LPG architecture on a 10 nm Intel process. Both parts are listed as Active production status and share the same 50th percentile ranking against all GPUs in the database.

The AMD Ryzen Z2 A GPU presents itself as the lower-power option, with a 15 W TDP compared to the Intel part's 65 W TDP. The Intel Arc Graphics 64EU Mobile offers higher raw compute figures: 1.792 TFLOPS FP32 versus 1.638 TFLOPS for the AMD, a 9.4% advantage. The Intel part also leads in pixel rate (28.00 GPixel/s versus 25.60 GPixel/s) and texture rate (56.00 GTexel/s versus 51.20 GTexel/s).

The AMD part counters with dedicated memory. It has 16 GB of LPDDR5 on a 128-bit bus with 102.4 GB/s of bandwidth. The Intel part relies on System Shared memory with System Dependent bandwidth, which means its memory performance is tied to the host system configuration. For scenarios where memory bandwidth is the limiting factor, the AMD part has a clear structural advantage.

Neither part has recorded benchmark scores in the database, so the verdict rests on architectural capabilities and measured specifications. The AMD Ryzen Z2 A GPU suits designs prioritizing power efficiency and predictable memory performance. The Intel Arc Graphics 64EU Mobile suits designs where raw compute throughput and the ability to draw on system memory capacity matter more than fixed power limits.

Architecture Differences

The AMD Ryzen Z2 A GPU is built on the Van Gogh chip using RDNA 2.0, fabricated on a 7 nm process at TSMC. The chip contains 2,400 million transistors on a 163 mm² die, resulting in a transistor density of 14.7M per mm². The Intel Arc Graphics 64EU Mobile uses the Meteor Lake chip with Xe-LPG architecture, fabricated on a 10 nm process at Intel. Transistor count and die size for the Intel part are not recorded in the database.

Both parts feature 512 shading units, 32 texture mapping units, and 16 raster operations pipelines. The AMD part includes 8 dedicated ray tracing cores, while the Intel part has no ray tracing core count listed. The AMD part supports DirectX 12 Ultimate (12_2), while the Intel part supports DirectX 12 (12_1), indicating a difference in feature level support. Both support OpenGL 4.6 and Vulkan 1.4.

The clock profiles differ substantially. The AMD part runs at a 1000 MHz base clock with a 1600 MHz boost clock. The Intel part runs at a 300 MHz base clock with a 1750 MHz boost clock. The Intel part's higher boost clock contributes to its compute advantage, but its lower base clock and higher 65 W TDP suggest a different power delivery profile. The AMD part's memory runs at 800 MHz with 6.4 Gbps effective speed.

Memory architecture is the most significant differentiator. The AMD part has 16 GB of dedicated LPDDR5 memory on a 128-bit bus, delivering 102.4 GB/s of bandwidth. The Intel part uses System Shared memory, meaning its capacity, bus width, and bandwidth are determined by the host system. The AMD part's dedicated memory ensures consistent bandwidth regardless of system configuration.

The display outputs also differ. The AMD part has a single USB Type-C output. The Intel part's display outputs are Portable Device Dependent, meaning they vary by the device it is integrated into. The Intel part uses a Ring Bus interface, while the AMD part has no bus interface listed. The Intel part is an IGP (integrated graphics processor) with a slot width of IGP, while the AMD part has no slot width listed.

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark results for these two parts, and neither part has individual benchmark scores. Wins are therefore determined by comparing the specification-derived performance metrics recorded in the database.

The Intel Arc Graphics 64EU Mobile holds the lead in raw compute throughput. Its FP32 figure of 1.792 TFLOPS exceeds the AMD part's 1.638 TFLOPS by 0.154 TFLOPS, a 9.4% advantage. The FP16 figures show the same ratio: the Intel part delivers 3.584 TFLOPS (2:1) versus the AMD part's 3.277 TFLOPS (2:1). This means for workloads that are shader-bound, the Intel part can complete more arithmetic operations per second.

The Intel part also leads in texture and pixel throughput. Its texture rate of 56.00 GTexel/s surpasses the AMD part's 51.20 GTexel/s by 4.80 GTexel/s, a 9.4% advantage. Its pixel rate of 28.00 GPixel/s surpasses the AMD part's 25.60 GPixel/s by 2.40 GPixel/s, also a 9.4% advantage. These figures scale directly with the FP32 advantage, confirming the Intel part's higher clock headroom at boost.

The AMD Ryzen Z2 A GPU does not lead in any of the recorded compute metrics. Its advantage lies in the memory subsystem. The 16 GB LPDDR5 configuration with 102.4 GB/s bandwidth is a fixed, dedicated resource. The Intel part's System Dependent bandwidth means its effective memory throughput is not guaranteed by the GPU specification alone; it depends on the host system's memory configuration. In practical terms, the AMD part offers deterministic memory performance, while the Intel part offers flexibility at the cost of predictability.

The power envelope also favors the AMD part. The 15 W TDP versus 65 W TDP is a 4.3x difference. This implies the AMD part can be deployed in thermally constrained designs where the Intel part would require more substantial cooling and power delivery. The AMD part's 7 nm process at TSMC, compared to Intel's 10 nm process, contributes to its lower power requirement.

Where Each One Wins

The AMD Ryzen Z2 A GPU wins in scenarios where power efficiency is the primary constraint. Its 15 W TDP allows deployment in thin-and-light devices, handheld consoles, or other battery-powered hardware where a 65 W component would be impractical. The dedicated 16 GB LPDDR5 memory with 102.4 GB/s bandwidth ensures that memory performance is consistent and not subject to system configuration. The 8 ray tracing cores provide hardware acceleration for ray-traced effects that the Intel part cannot offer at the hardware level. The DirectX 12 Ultimate support also enables the full feature set of modern graphics APIs, including features that require the 12_2 feature level.

The Intel Arc Graphics 64EU Mobile wins in scenarios where raw compute throughput is the priority. Its 1.792 TFLOPS FP32 performance, 56.00 GTexel/s texture rate, and 28.00 GPixel/s pixel rate are all 9.4% higher than the AMD part. This advantage applies to shader-heavy workloads, texture-bound rendering, and fill-rate-limited scenarios. The higher boost clock of 1750 MHz versus 1600 MHz provides the headroom for these gains. The System Shared memory model means the Intel part can draw on whatever memory capacity the host system provides, which could exceed the AMD part's fixed 16 GB in systems with larger memory pools. The Meteor Lake architecture with Xe-LPG is designed for integration into portable devices, as its Portable Device Dependent display outputs suggest.

The data shows that neither part is universally superior. The AMD Ryzen Z2 A GPU is the choice for power-limited, memory-sensitive designs that value dedicated bandwidth and ray tracing capability. The Intel Arc Graphics 64EU Mobile is the choice for compute-bound workloads where the additional 9.4% throughput in every measured rate metric matters more than power draw. The 50th percentile ranking for both parts indicates they occupy the same market tier, but their design philosophies lead to different application fits.
