AMD Ryzen Z2 GPU vs Intel Data Center GPU Max Subsystem Comparison

The Verdict

The database shows two fundamentally different products that happen to share a GPU label. The AMD Ryzen Z2 GPU is a compact, integrated-class part built for constrained systems, while the Intel Data Center GPU Max Subsystem is a massive accelerator designed for compute-heavy server workloads. Neither is a direct substitute for the other, and the data confirms they target separate markets entirely.

For power-constrained or mobile applications, the AMD Ryzen Z2 GPU is the only realistic option. Its 28 W TDP, lack of power connectors, and single USB Type-C display output indicate a part designed to fit inside a small chassis without external power delivery. The Intel part, by contrast, requires a 2400 W TDP, a 2800 W suggested power supply, and a 16-pin connector, making it unsuitable for anything outside a dedicated server rack.

For data center compute tasks, the Intel Data Center GPU Max Subsystem dominates in raw throughput. Its FP32 performance of 52.43 TFLOPS is more than six times the AMD part's 8.294 TFLOPS. Its memory bandwidth of 3.21 TB/s versus 119.9 GB/s represents a 26.8x advantage. Any workload that scales with compute or memory bandwidth will favor Intel overwhelmingly.

The percentile data places both parts at the 50th percentile against all GPUs, suggesting they serve distinct niches rather than competing head-to-head. The AMD Ryzen Z2 GPU achieves this percentile with a 178 mm² die and 25,390 million transistors, while Intel reaches the same percentile with a 1280 mm² die and 100,000 million transistors. The efficiency difference is stark: AMD packs 142.6 million transistors per mm² on a 4 nm TSMC process, while Intel manages 78.1 million per mm² on a 10 nm Intel process.

Architecture Differences

The two GPUs use entirely different architectures, process nodes, and memory technologies. The AMD Ryzen Z2 GPU is built on RDNA 3.0 architecture using the Hawk Point chip, fabricated on a 4 nm process at TSMC. The Intel Data Center GPU Max Subsystem uses Generation 12.5 architecture with the Ponte Vecchio chip, fabricated on a 10 nm process at Intel.

The transistor counts reflect the scale difference. AMD's chip contains 25,390 million transistors on a 178 mm² die, while Intel's chip contains 100,000 million transistors on a 1280 mm² die. The transistor density figures show AMD's process advantage: 142.6 million transistors per mm² versus Intel's 78.1 million per mm².

Memory architecture diverges completely. The AMD part uses 16 GB of LPDDR5X on a 128-bit bus, delivering 119.9 GB/s bandwidth. The Intel part uses 128 GB of HBM2e on an 8192-bit bus, delivering 3.21 TB/s. The memory clock rates also differ: AMD's memory runs at 937 MHz (7.5 Gbps effective), while Intel's runs at 1565 MHz (3.1 Gbps effective).

Compute resources scale accordingly. The AMD GPU has 768 shading units, 48 texture mapping units, 32 raster operations units, and 12 ray tracing cores. The Intel GPU has 16,384 shading units, 1,024 texture mapping units, zero raster operations units, and 128 ray tracing cores. The zero ROP count on Intel reflects its lack of display output capability, confirmed by the "No outputs" field for display connections.

API support differs slightly. AMD supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Intel supports DirectX 12 (12_1), OpenGL 4.6, and no Vulkan support listed. The DirectX version difference (12_2 versus 12_1) indicates AMD's architecture supports newer rendering features.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between these two GPUs, and both parts show zero recorded benchmark scores. However, the specification data provides clear quantitative comparisons for theoretical peak performance.

The largest single advantage belongs to Intel in memory bandwidth. The Intel Data Center GPU Max Subsystem delivers 3.21 TB/s against AMD's 119.9 GB/s, a 26.8x margin. This gap reflects the fundamental difference in memory architecture: HBM2e on an 8192-bit bus versus LPDDR5X on a 128-bit bus.

In raw compute, Intel leads by 6.3x in both FP32 and FP16, with 52.43 TFLOPS versus 8.294 TFLOPS. The texture rate shows a similar pattern: Intel's 1,638.4 GTexel/s versus AMD's 129.6 GTexel/s, a 12.6x difference. Intel's 1,024 TMUs dwarf AMD's 48, explaining the texture throughput gap.

The pixel rate comparison inverts the pattern. AMD's 86.40 GPixel/s versus Intel's 0 MPixel/s reflects the Intel part's lack of raster operations units. With zero ROPs and no display outputs, the Intel GPU cannot perform traditional pixel rasterization, while the AMD part's 32 ROPs enable this function.

Clock speeds show an interesting reversal. AMD's boost clock of 2700 MHz exceeds Intel's 1600 MHz by 68.75%. AMD's base clock of 800 MHz is lower than Intel's 900 MHz, but AMD's boost clock advantage suggests a more aggressive frequency scaling capability within its 28 W power envelope.

Shading unit counts favor Intel massively: 16,384 versus 768, a 21.3x difference. Ray tracing cores follow the same direction with 128 versus 12, a 10.7x margin. These resource counts align with Intel's data center positioning, where massive parallel throughput matters more than per-core efficiency.

The transistor density figures tell a process technology story. AMD's 142.6 million transistors per mm² on 4 nm TSMC exceeds Intel's 78.1 million per mm² on 10 nm Intel by 82.6%. Despite this density advantage, Intel's larger die (1280 mm² versus 178 mm²) accommodates nearly 4x more total transistors.

Where Each One Wins

The AMD Ryzen Z2 GPU wins in every metric related to power efficiency and physical integration. Its 28 W TDP compared to Intel's 2400 W represents an 85.7x reduction in power consumption. The lack of power connectors means the AMD part draws power directly from its host system, while Intel requires a dedicated 16-pin connection and a 2800 W suggested power supply. The single USB Type-C output gives AMD the only display capability between the two.

AMD also wins on process technology metrics. The 4 nm TSMC node versus Intel's 10 nm node, combined with 142.6 million transistors per mm² versus 78.1 million, shows AMD's manufacturing advantage. The higher boost clock of 2700 MHz versus 1600 MHz further indicates AMD's frequency headroom at low power.

The Intel Data Center GPU Max Subsystem wins in every throughput-oriented category. Its 16,384 shading units, 1,024 TMUs, and 128 ray tracing cores provide the compute resources for data center workloads. The 128 GB HBM2e memory with 3.21 TB/s bandwidth enables large dataset processing that would be impossible with AMD's 16 GB LPDDR5X at 119.9 GB/s.

The FP32 and FP16 figures of 52.43 TFLOPS position Intel for high-performance computing tasks, while AMD's 8.294 TFLOPS suits lighter graphics workloads. The texture rate of 1,638.4 GTexel/s versus 129.6 GTexel/s reinforces Intel's advantage in texture-heavy compute, even though its zero ROP count and zero pixel rate exclude it from traditional rasterization.

The release dates show Intel shipped first on 2023-01-09, with AMD following on 2024-12-31. Intel's successor is listed as H3C Graphics, while AMD has no successor listed. Both parts remain in active production according to the database.

The data indicates a clean split: AMD for integrated, power-efficient graphics with display output, Intel for massive parallel compute without any display functionality. The 50th percentile ranking for both against all GPUs suggests each part is average within its respective class, but the classes themselves could not be more different.
