AMD Ryzen AI Z2 Extreme GPU vs Intel Arc Pro B70 Comparison

Architecture Differences

The AMD Ryzen AI Z2 Extreme GPU and Intel Arc Pro B70 represent two fundamentally different design philosophies within the same performance percentile. The database places both parts at the 50th percentile among all GPUs, indicating they occupy similar overall standing despite their architectural divergence.

AMD's offering is built on the Strix Point chip using the RDNA 3.5 architecture, fabricated on TSMC's 4 nm process. The die measures 233 mm² and contains 34,000 million transistors, yielding a transistor density of 145.9M per mm². This is a console-oriented GPU generation design, and the compact footprint reflects its integration-focused purpose. The chip operates with a modest power envelope of 28 W, which aligns with its role in portable and embedded systems.

Intel's Arc Pro B70 uses the BMG-G31 chip based on the Xe2-HPG architecture, belonging to the Battlemage Pro Series. It is manufactured on TSMC's 5 nm process, with a larger die size of 368 mm². Transistor counts are not recorded in the database for this part. The power draw is substantially higher at 230 W, requiring a dual-slot cooler, a single 8-pin power connector, and a suggested 550 W power supply. The physical dimensions are listed at 267 mm in length, 110 mm in height, and 39 mm in width.

The compute configurations differ dramatically. The AMD GPU carries 1,024 shading units, 64 texture mapping units, and 48 render output units, along with 16 ray tracing cores. Intel's part scales this up considerably: 4,096 shading units, 256 TMUs, 128 ROPs, and 32 ray tracing cores. This 4x advantage in raw shader count and 2x advantage in RT cores sets the stage for the performance gap observed in the data.

Memory subsystems also diverge. AMD pairs its GPU with 16 GB of LPDDR5X memory on a 256-bit bus, running at an effective 8 Gbps with a memory clock of 1000 MHz. This yields 256.0 GB/s of bandwidth. Intel equips the Arc Pro B70 with 32 GB of GDDR6 memory, also on a 256-bit bus, but at an effective 19 Gbps with a 2375 MHz memory clock. The resulting bandwidth is 608.0 GB/s, which is 2.375 times higher than AMD's figure.

Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level feature parity exists. The display outputs differ: AMD provides a single USB Type-C connector, while Intel offers one HDMI 2.1a and three DisplayPort 2.1 outputs. The bus interface is PCIe 5.0 x16 for Intel, while AMD's bus interface is not recorded in the database.

Head-to-Head Benchmarks

The benchmark data shows a clear and consistent advantage for the Intel Arc Pro B70 across every recorded metric, though the scale of the advantage varies by workload type.

In raw pixel throughput, Intel's GPU delivers 358.4 GPixel/s compared to AMD's 129.6 GPixel/s. This represents a 2.77x advantage, driven by Intel's higher ROP count (128 versus 48) and its significantly higher boost clock of 2800 MHz versus 2700 MHz. The base clock difference is more pronounced: Intel runs at 2280 MHz while AMD sits at 800 MHz, a 2.85x gap that persists into the boost state.

Texture rate follows a similar pattern. Intel achieves 716.8 GTexel/s against AMD's 172.8 GTexel/s, a 4.15x advantage. This is a direct consequence of Intel's 256 TMUs versus AMD's 64, compounded by the clock speed differential.

The floating-point compute figures reveal the largest divergence. Intel's FP32 performance is 22.94 TFLOPS, while AMD manages 5.530 TFLOPS. This is a 4.15x gap, identical in ratio to the texture rate. AMD's FP16 throughput is listed at 5.530 TFLOPS with a 1:1 ratio, meaning it does not gain any advantage in half-precision workloads. Intel's FP16 figure is 45.88 TFLOPS at a 2:1 ratio, effectively doubling its FP32 throughput. This gives Intel an 8.30x advantage in FP16 compute, a critical metric for AI inference and certain content creation workloads.

Memory bandwidth shows Intel ahead at 608.0 GB/s versus 256.0 GB/s, a 2.375x advantage. The memory clock difference is notable: Intel's 2375 MHz GDDR6 operates at more than double AMD's 1000 MHz LPDDR5X, and the effective data rate of 19 Gbps versus 8 Gbps compounds this into a substantial bandwidth lead.

The pixel rate advantage of 2.77x is actually the smallest gap among the major metrics, suggesting that AMD's RDNA 3.5 architecture extracts relatively more efficiency from its smaller ROP pool than raw specifications would imply. However, the overall pattern is unambiguous: Intel leads in every computed metric, with advantages ranging from roughly 2.4x to over 8x depending on the workload.

Where Each One Wins

The Intel Arc Pro B70 dominates the entire recorded performance spectrum. Its 32 GB GDDR6 memory pool at 608.0 GB/s positions it for large dataset workloads, high-resolution rendering, and compute-heavy tasks that demand substantial memory capacity and bandwidth. The 22.94 TFLOPS FP32 throughput and 45.88 TFLOPS FP16 capability indicate strong suitability for professional rendering, simulation, and machine learning inference tasks. The PCIe 5.0 x16 interface provides high host bandwidth for data transfer, and the multiple display outputs (one HDMI 2.1a, three DisplayPort 2.1) support multi-monitor professional configurations.

The AMD Ryzen AI Z2 Extreme GPU, while trailing in every metric, offers a different value proposition based on its physical and electrical characteristics. At 28 W TDP with no power connectors required, it can operate in systems where power delivery and cooling are constrained. The single USB Type-C display output suggests a mobile or compact form factor focus. Its 16 GB LPDDR5X memory, while slower, still provides reasonable capacity for its class. The 233 mm² die size and 4 nm process indicate a design optimized for efficiency rather than absolute throughput.

The release dates in the database show Intel's part arriving later, which may reflect a newer design cycle. AMD's 5.530 TFLOPS FP32 and 5.530 TFLOPS FP16 (1:1) figures indicate a balanced compute profile, but one that is simply outclassed by Intel's raw hardware resources.

For workloads that prioritize power efficiency, compact integration, and minimal cooling requirements, AMD's design holds theoretical advantages. For workloads that prioritize raw compute throughput, memory bandwidth, and capacity, Intel's part is the only choice based on recorded data. The 4x shader count, 4x TMU count, and 2.67x ROP count advantages for Intel are decisive across all measured categories.
