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

Where Each One Wins

The recorded data splits these two integrated graphics solutions into very different performance classes. The AMD Ryzen Z2 A GPU, built on the Van Gogh chip with RDNA 2.0 architecture, sits at the 50th percentile among all GPUs in the database. The Intel Arc Graphics 64EU, based on Arrow Lake-S with Xe-LPG architecture, lands at just the 3rd percentile.

This percentile gap is stark. The AMD part is positioned in the middle of the field, while the Intel Arc Graphics 64EU sits near the very bottom. The only benchmark score recorded for the Intel part, 3DMark Steel Nomad DX12, is 733 points. The AMD Ryzen Z2 A GPU has no benchmark scores recorded in the database, so direct numerical comparison on identical tests is not possible. However, the percentile data provides context: a 50th percentile ranking versus a 3rd percentile ranking indicates the AMD solution occupies a fundamentally different performance tier.

For use cases, the AMD Ryzen Z2 A GPU with its 15 W TDP and 16 GB of dedicated LPDDR5 memory is suited to scenarios where sustained graphics workload and memory capacity matter. The Intel Arc Graphics 64EU, with a 65 W TDP and system-shared memory, targets a different deployment model entirely. The AMD part carries its own memory, which means it does not contend with the system for bandwidth. The Intel part relies on whatever the host platform provides, with bandwidth listed as "System Dependent."

The Intel part wins in raw clock speed. Its boost clock reaches 1900 MHz compared to the AMD's 1600 MHz. It also produces higher pixel and texture rates: 30.40 GPixel/s versus 25.60 GPixel/s, and 60.80 GTexel/s versus 51.20 GTexel/s. FP32 throughput favors Intel as well, at 1.946 TFLOPS against 1.638 TFLOPS. These are arithmetic wins for Intel on paper, but the percentile data suggests real-world results may not follow that pattern.

The AMD part wins on memory configuration. It has 16 GB of dedicated LPDDR5 with a 128-bit bus and 102.4 GB/s bandwidth. The Intel part has no dedicated memory, no fixed bus width, and no fixed bandwidth figure. For workloads sensitive to memory latency and capacity, the AMD configuration provides a concrete advantage.

Architecture Differences

The two parts come from different manufacturing generations. The AMD Ryzen Z2 A GPU uses a 7 nm process at TSMC, while the Intel Arc Graphics 64EU uses a 3 nm process, also at TSMC. The Intel chip, Arrow Lake-S, packs 17,800 million transistors on a 243 mm² die, yielding a transistor density of 73.3M per mm². The AMD Van Gogh chip contains 2,400 million transistors on a 163 mm² die, for a density of 14.7M per mm². The Intel die is larger, denser, and carries over seven times more transistors.

Both parts share identical shading unit counts at 512, TMU counts at 32, and ROP counts at 16. They also share the same API support: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The AMD part includes 8 ray tracing cores, while the Intel part lists no ray tracing core count. Neither part lists tensor cores.

Memory architecture diverges sharply. AMD uses 16 GB of LPDDR5 on a 128-bit interface with 102.4 GB/s bandwidth, clocked at 800 MHz with 6.4 Gbps effective. Intel uses system-shared memory with no fixed size, type, bus width, or bandwidth; all are listed as "System Shared" or "System Dependent." The AMD part has a fixed memory clock, the Intel part does not.

Clock behavior also differs. The AMD base clock is 1000 MHz, boosting to 1600 MHz. The Intel base clock is far lower at 300 MHz, but boosts to 1900 MHz. This suggests the Intel part relies heavily on boost behavior, while the AMD part runs at a higher sustained baseline. The TDP figures reflect this: AMD at 15 W, Intel at 65 W. The Intel part draws over four times the power budget.

Physical integration differs as well. The Intel Arc Graphics 64EU is an IGP, meaning it is built into the processor package. The AMD Ryzen Z2 A GPU is listed as a console GPU. The Intel part uses a Ring Bus interface, while the AMD part has no bus interface listed. Display outputs also differ: AMD provides 1x USB Type-C, while Intel's outputs are motherboard dependent.

Process node advantage belongs to Intel at 3 nm, but the AMD part consumes far less power. Transistor density favors Intel by a wide margin, but the AMD part achieves its performance class with a much smaller transistor budget.

The Verdict

The data presents a clear choice based on deployment context. The AMD Ryzen Z2 A GPU, with its 50th percentile ranking, dedicated 16 GB memory, and 15 W TDP, is the higher-performing option in the database's overall GPU hierarchy. The Intel Arc Graphics 64EU, at the 3rd percentile, sits near the bottom of that same hierarchy.

For scenarios requiring a self-contained graphics solution with dedicated memory and low power consumption, the AMD part is the stronger selection. Its 16 GB LPDDR5 configuration with 102.4 GB/s bandwidth provides a fixed memory subsystem that does not depend on host platform variables. The 15 W TDP makes it suitable for constrained power environments.

For scenarios requiring the graphics to be integrated into the processor with no separate memory allocation, the Intel part is the only option of the two. Its system-shared memory model means the host platform determines actual performance. The 65 W TDP indicates a higher power ceiling, but the recorded benchmark score of 733 in 3DMark Steel Nomad DX12 and the 3rd percentile ranking suggest that power budget does not translate into strong results.

The Intel part's nearest rivals in the database are telling. It scores identically to the Intel Arc Graphics 32EU and Intel Arc Graphics 24EU, both at 733 points with a 0% delta. It is 1.4% ahead of the AMD Radeon HD 6470M, which scores 723, and 2.4% behind the NVIDIA GeForce GT 415M, which scores 751. These are all low-end parts from previous generations. The AMD Ryzen Z2 A GPU has no rivals listed, but its 50th percentile placement puts it in a completely different performance bracket.

Users who prioritize raw performance, dedicated memory, and low power should select the AMD Ryzen Z2 A GPU. Users who require an integrated processor graphics solution with no dedicated memory and are willing to accept bottom-tier benchmark placement should select the Intel Arc Graphics 64EU.

Head-to-Head Benchmarks

The head-to-head benchmark table in the database is empty, so no direct comparison scores exist between these two parts. The only recorded benchmark belongs to the Intel Arc Graphics 64EU: 733 points in 3DMark Steel Nomad DX12. The AMD Ryzen Z2 A GPU has no individual benchmark entries.

Despite the absence of direct head-to-head tests, the surrounding data allows for meaningful comparison. The Intel part's 733-point score places it at the 3rd percentile. Its nearest rivals include the Intel Arc Graphics 32EU and Intel Arc Graphics 24EU, both scoring exactly 733 with a 0% delta. The AMD Radeon HD 6470M scores 723, which is 1.4% behind the Intel part. The NVIDIA GeForce GT 415M scores 751, which is 2.4% ahead.

The AMD Ryzen Z2 A GPU's 50th percentile placement means half of all GPUs in the database score below it, and half score above. The Intel part's 3rd percentile means 97% of GPUs score above it. This is the single largest differentiator in the entire comparison.

On theoretical throughput metrics, the Intel part wins several categories. FP32 performance is 1.946 TFLOPS versus 1.638 TFLOPS, a 18.8% advantage. Pixel rate is 30.40 GPixel/s versus 25.60 GPixel/s, a 18.75% advantage. Texture rate is 60.80 GTexel/s versus 51.20 GTexel/s, an 18.75% advantage. The Intel part also boosts 300 MHz higher.

On memory, the AMD part wins decisively. The 16 GB dedicated LPDDR5 with 102.4 GB/s bandwidth is a fixed, measurable configuration. The Intel part's system-shared memory has no fixed bandwidth, no fixed size, and no fixed bus width. In the database, its memory bandwidth is listed as "System Dependent," which means it cannot be compared as a standalone figure.

The power efficiency comparison favors AMD. At 15 W versus 65 W, the AMD part delivers its 50th percentile performance with less than a quarter of the power budget. The Intel part consumes 65 W to achieve a 3rd percentile score. Even if the Intel part's theoretical throughput numbers are higher, the recorded benchmark placement indicates those advantages do not translate into competitive real-world results.

The transistor and die data further contextualize the comparison. Intel uses 17,800 million transistors on 243 mm² with a density of 73.3M per mm². AMD uses 2,400 million transistors on 163 mm² with a density of 14.7M per mm². The Intel chip has substantially more silicon resources at its disposal, yet the benchmark percentile outcome does not reflect that investment.

The production status for both parts is listed as Active. The Intel release date is 2024-10-23, while the AMD release date is 2024-12-31. Neither part has a launch MSRP in the database, so no price comparison is available. The AMD part lists a predecessor of none, while the Intel part lists HD Graphics as its predecessor.

In summary, the AMD Ryzen Z2 A GPU wins on benchmark percentile, memory configuration, power efficiency, and ray tracing support. The Intel Arc Graphics 64EU wins on clock speed, pixel rate, texture rate, FP32 throughput, process node, and transistor density. The recorded benchmark data, however, places the AMD part in a substantially higher performance tier.
