AMD Ryzen AI Z2 Extreme GPU vs Intel Arc B770 Comparison

The Verdict

The data in this comparison is unambiguous. The Intel Arc B770 is the substantially stronger graphics processor across nearly every measurable hardware metric, while the AMD Ryzen AI Z2 Extreme GPU is a low-power, integrated-class solution designed for a fundamentally different role. The Arc B770 delivers roughly 3.6 times the FP32 compute of the AMD part (19.66 TFLOPS versus 5.530 TFLOPS), more than double the texture rate (614.4 GTexel/s versus 172.8 GTexel/s), and more than double the pixel rate (307.2 GPixel/s versus 129.6 GPixel/s). The AMD part counters with dramatically lower power draw at 28 W versus 225 W, making it the appropriate choice for compact, power-constrained systems. The recorded data shows no benchmark scores for either product, so the hardware specification comparison stands as the primary evidence. Buyers seeking maximum rendering performance should choose the Intel Arc B770; buyers prioritizing minimum power consumption in a small form factor should choose the AMD Ryzen AI Z2 Extreme GPU.

Architecture Differences

The two processors come from different architectural lineages. The AMD Ryzen AI Z2 Extreme GPU uses the RDNA 3.5 architecture on a Strix Point chip, fabricated on TSMC's 4 nm process. The Intel Arc B770 uses the Xe2-HPG architecture on the BMG-G31 chip, belonging to the Battlemage (Arc 7) generation, fabricated on TSMC's 5 nm process. Both processors support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so the API feature set is identical.

The transistor counts tell a revealing story. AMD lists 34,000 million transistors on a 233 mm² die, giving a density of 145.9M / mm². Intel does not disclose the transistor count for the BMG-G31 chip but uses a larger 368 mm² die. The Intel die is approximately 58% larger in area than the AMD die, which aligns with its far greater resource allocation.

Shader resources differ enormously. The AMD part has 1024 shading units, 64 texture mapping units, 48 render output units, and 16 ray tracing cores. The Intel part has 4096 shading units, exactly four times the AMD count, along with 256 TMUs, 128 ROPs, and 32 ray tracing cores. The Intel GPU doubles the ray tracing core count and quadruples the fixed-function throughput resources.

Clock behavior also differs. The AMD chip runs a base clock of 800 MHz and boosts to 2700 MHz, a wide frequency range that reflects its power-conscious design. The Intel chip runs a base clock of 2100 MHz and boosts to 2400 MHz, a much narrower range with a higher floor. The AMD part achieves its peak boost at a lower thermal envelope, while Intel runs closer to its maximum frequency continuously.

Where Each One Wins

The AMD Ryzen AI Z2 Extreme GPU wins in power efficiency and physical integration. Its 28 W TDP is a fraction of the Intel part's 225 W TDP, and it requires no power connectors at all, drawing everything from its slot or system integration. The display output is a single USB Type-C port, which suits ultra-compact or embedded designs. Its 4 nm process node from TSMC provides a density advantage, fitting 34,000 million transistors into 233 mm² compared to Intel's larger 368 mm² die with an undisclosed transistor count.

The Intel Arc B770 wins in raw performance capacity. Its FP32 throughput of 19.66 TFLOPS is more than triple the AMD figure, and its FP16 throughput of 39.32 TFLOPS (2:1 ratio) is more than seven times the AMD FP16 figure of 5.530 TFLOPS (1:1 ratio). Memory bandwidth is exactly double: 512.0 GB/s versus 256.0 GB/s. The Intel card uses GDDR6 memory at 16 Gbps effective, while AMD uses LPDDR5X at 8 Gbps effective. The Intel card provides a PCIe 4.0 x16 bus interface, whereas the AMD part lists no bus interface, and offers a broader display output set with 1x HDMI 2.1a and 3x DisplayPort 2.1. The Intel card also requires a 550 W suggested PSU and uses a dual-slot cooler with 1x 6-pin plus 1x 8-pin power connectors.

Head-to-Head Benchmarks

No head-to-head benchmark results are recorded in the database for this pairing, so the comparison rests entirely on the specification data. The largest single delta is in FP16 throughput. The Intel Arc B770 delivers 39.32 TFLOPS with a 2:1 FP16 to FP32 ratio, while the AMD part delivers 5.530 TFLOPS with a 1:1 ratio. That is a 7.1 times advantage for Intel in half-precision workloads, which matters for compute tasks that use FP16 accumulation.

In FP32, the Intel Arc B770 delivers 19.66 TFLOPS versus 5.530 TFLOPS, a 3.6 times advantage. Texture fill rate follows the same pattern: 614.4 GTexel/s versus 172.8 GTexel/s, a 3.6 times advantage. Pixel fill rate shows a 2.4 times advantage for Intel at 307.2 GPixel/s versus 129.6 GPixel/s. The shading unit count scales identically to the FP32 ratio, with 4096 units versus 1024 units.

Memory bandwidth is the other major differentiator. The Intel card's 512.0 GB/s is exactly twice the AMD card's 256.0 GB/s. The memory clock difference is also exactly double: 2000 MHz (16 Gbps effective) versus 1000 MHz (8 Gbps effective). Both cards carry 16 GB of memory on a 256 bit bus, so the bandwidth gap comes entirely from memory type and clock speed.

Clock behavior complicates the raw comparison. The AMD chip has a lower base clock of 800 MHz but a higher boost clock of 2700 MHz, while the Intel chip runs 2100 MHz base and 2400 MHz boost. The AMD boost clock is 300 MHz higher than Intel's boost clock, but the resource disparity is so large that this frequency advantage does not close the performance gap in any throughput metric.

The pixel rate gap deserves attention. The AMD card achieves 129.6 GPixel/s from 48 ROPs at its boost clock. The Intel card achieves 307.2 GPixel/s from 128 ROPs. The ROP count ratio is 2.67, and the pixel rate ratio is 2.37, so the AMD part narrows the gap slightly through its higher boost clock. The texture rate ratio is exactly 4.0, matching the TMU count ratio of 256 to 64, which shows that texture throughput scales purely with resource count.

The die size difference also matters for thermal and physical design. The Intel die measures 368 mm², which is 135 mm² larger than the AMD die at 233 mm². The AMD die achieves a transistor density of 145.9M / mm², while Intel does not disclose its density. The AMD design packs 34,000 million transistors into a smaller area on a smaller process node, which explains its ability to operate at 28 W with no power connectors.
